Please reach out if you think the game vs navigation input sharing could be improved. + + - REMOTE INPUTS SHARING & MOUSE EMULATION + - PS4/PS5 users: Consider emulating a mouse cursor with DualShock touch pad or a spare analog stick as a mouse-emulation fallback. + - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + run examples/libs/synergy/uSynergy.c (on your console/tablet/phone app) + in order to share your PC mouse/keyboard. + - See https://github.com/ocornut/imgui/wiki/Useful-Extensions#remoting for other remoting solutions. + - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the io.ConfigNavMoveSetMousePos flag. + Enabling io.ConfigNavMoveSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs Dear ImGui to move your mouse cursor along with navigation movements. + When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved. + When that happens your backend NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the backends in examples/ do that. + (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, Dear ImGui will misbehave as it will see your mouse moving back & forth!) + (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want + to set a boolean to ignore your other external mouse positions until the external source is moved again.) + + + PROGRAMMER GUIDE + ================ + + READ FIRST + ---------- + - Remember to check the wonderful Wiki: https://github.com/ocornut/imgui/wiki + - Your code creates the UI every frame of your application loop, if your code doesn't run the UI is gone! + The UI can be highly dynamic, there are no construction or destruction steps, less superfluous + data retention on your side, less state duplication, less state synchronization, fewer bugs. + - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features. + Or browse pthom's online imgui_explorer: https://pthom.github.io/imgui_explorer for a web version w/ source code browser. + - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build. + - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori). + You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in Wiki. + - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances. + For every application frame, your UI code will be called only once. This is in contrast to e.g. Unity's implementation of an IMGUI, + where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches. + - Our origin is on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right. + - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected). + If you get an assert, read the messages and comments around the assert. + - This codebase aims to be highly optimized: + - A typical idle frame should never call malloc/free. + - We rely on a maximum of constant-time or O(N) algorithms. Limiting searches/scans as much as possible. + - We put particular energy in making sure performances are decent with typical "Debug" build settings as well. + Which mean we tend to avoid over-relying on "zero-cost abstraction" as they aren't zero-cost at all. + - This codebase aims to be both highly opinionated and highly flexible: + - This code works because of the things it choose to solve or not solve. + - C++: this is a pragmatic C-ish codebase: we don't use fancy C++ features, we don't include C++ headers, + and ImGui:: is a namespace. We rarely use member functions (and when we did, I am mostly regretting it now). + This is to increase compatibility, increase maintainability and facilitate use from other languages. + - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types. + See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that. + We can can optionally export math operators for ImVec2/ImVec4 using IMGUI_DEFINE_MATH_OPERATORS, which we use internally. + - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction + (so don't use ImVector in your code or at our own risk!). + - Building: We don't use nor mandate a build system for the main library. + This is in an effort to ensure that it works in the real world aka with any esoteric build setup. + This is also because providing a build system for the main library would be of little-value. + The build problems are almost never coming from the main library but from specific backends. + + + HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI + ---------------------------------------------- + - Update submodule or copy/overwrite every file. + - About imconfig.h: + - You may modify your copy of imconfig.h, in this case don't overwrite it. + - or you may locally branch to modify imconfig.h and merge/rebase latest. + - or you may '#define IMGUI_USER_CONFIG "my_config_file.h"' globally from your build system to + specify a custom path for your imconfig.h file and instead not have to modify the default one. + + - Overwrite all the sources files except for imconfig.h (if you have modified your copy of imconfig.h) + - Or maintain your own branch where you have imconfig.h modified as a top-most commit which you can regularly rebase over "master". + - You can also use '#define IMGUI_USER_CONFIG "my_config_file.h" to redirect configuration to your own file. + - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes. + If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed + from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will + likely be a comment about it. Please report any issue to the GitHub page! + - To find out usage of old API, you can add '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' in your configuration file. + - Try to keep your copy of Dear ImGui reasonably up to date! + + + GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE + --------------------------------------------------------------- + - See https://github.com/ocornut/imgui/wiki/Getting-Started. + - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library. + - In the majority of cases you should be able to use unmodified backends files available in the backends/ folder. + - Add the Dear ImGui source files + selected backend source files to your projects or using your preferred build system. + It is recommended you build and statically link the .cpp files as part of your project and NOT as a shared library (DLL). + - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types. + - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them. + - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide. + Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render" + phases of your own application. All rendering information is stored into command-lists that you will retrieve after calling ImGui::Render(). + - Refer to the backends and demo applications in the examples/ folder for instruction on how to setup your code. + - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder. + + + HOW A SIMPLE APPLICATION MAY LOOK LIKE + -------------------------------------- + + USING THE EXAMPLE BACKENDS (= imgui_impl_XXX.cpp files from the backends/ folder). + The sub-folders in examples/ contain examples applications following this structure. + + // Application init: create a dear imgui context, setup some options, load fonts + ImGui::CreateContext(); + ImGuiIO& io = ImGui::GetIO(); + // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. + // TODO: Fill optional fields of the io structure later. + // TODO: Load TTF/OTF fonts if you don't want to use the default font. + + // Initialize helper Platform and Renderer backends (here we are using imgui_impl_win32.cpp and imgui_impl_dx11.cpp) + ImGui_ImplWin32_Init(hwnd); + ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext); + + // Application main loop + while (true) + { + // Feed inputs to dear imgui, start new frame + ImGui_ImplDX11_NewFrame(); + ImGui_ImplWin32_NewFrame(); + ImGui::NewFrame(); + + // Any application code here + ImGui::Text("Hello, world!"); + + // Render dear imgui into framebuffer + ImGui::Render(); + ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData()); + g_pSwapChain->Present(1, 0); + } + + // Shutdown + ImGui_ImplDX11_Shutdown(); + ImGui_ImplWin32_Shutdown(); + ImGui::DestroyContext(); + + To decide whether to dispatch mouse/keyboard inputs to Dear ImGui to the rest of your application, + you should read the 'io.WantCaptureMouse', 'io.WantCaptureKeyboard' and 'io.WantTextInput' flags!

(#9476) + - Before: DragFloat() with user typing "123" --> write back 1, then 12, then 123. + - After: DragFloat() with user typing "123" --> write back 123 when validated/unfocused. + You can enable the flag back for a given scope if needed by specific widget/behavior. + - 2026/07/20 (1.92.9) - ImDrawData: marked ImDrawData::CmdListsCount as obsolete (technically was obsoleted in 1.89.8). + - Before: draw_data->CmdListsCount + - After: draw_data->CmdLists.Size + - 2026/07/08 (1.92.9) - Drag and Drop: commented out legacy name `ImGuiDragDropFlags_SourceAutoExpirePayload` which obsoleted in 1.90.9 (July 2024). Use `ImGuiDragDropFlags_PayloadAutoExpire`. + - 2026/07/06 (1.92.9) - ColorEdit: obsoleted SetColorEditOptions() function added in 1.51 (June 2017) in favor of directly poking to io.ConfigColorEditFlags. More consistent and easier to discover. + - 2026/06/02 (1.92.9) - TreeNode: commented out legacy name ImGuiTreeNodeFlags_SpanTextWidth which was obsoleted in 1.90.7 (May 2024). Use ImGuiTreeNodeFlags_SpanLabelWidth instead. + - 2026/05/07 (1.92.8) - DrawList: swapped the last two arguments of AddRect(), AddPolyline(), PathStroke(). + - Before: void ImDrawList::AddRect(ImVec2 p_min, ImVec2 p_max, ImU32 col, float rounding = 0.0f, ImDrawFlags flags = 0, float thickness = 1.0f); + - After: void ImDrawList::AddRect(ImVec2 p_min, ImVec2 p_max, ImU32 col, float rounding = 0.0f, float thickness = 1.0f, ImDrawFlags flags = 0); + - Before: void ImDrawList::AddPolyline(const ImVec2* points, int num_points, ImU32 col, ImDrawFlags flags, float thickness); + - After: void ImDrawList::AddPolyline(const ImVec2* points, int num_points, ImU32 col, float thickness, ImDrawFlags flags = 0); + - Before: void ImDrawList::PathStroke(ImU32 col, ImDrawFlags flags = 0, float thickness = 1.0f); + - After: void ImDrawList::PathStroke(ImU32 col, float thickness = 1.0f, ImDrawFlags flags = 0); + Added inline redirection functions when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is off. + Marked the old functions are =delete when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is on, to allow for better type-checking. + Effectively the typical call site is changing from: + - Before: window->DrawList->AddRect(p_min, p_max, color, rounding, ImDrawFlags_None, border_size); + - After: window->DrawList->AddRect(p_min, p_max, color, rounding, border_size); + Notes: + - Users of C++ and other languages with type-checking will be notified at compile-time of any mistakes. + - Users of high-level bindings or languages with no type-checking will be notified at runtime via an assert for invalid flags value. + If you are a binding maintainer consider doing something to facilitate transition or error detection. + - This is perhaps the worst breaking change in our history :( but it makes ImDrawList function signatures consistent. + As we are aiming to add flags and features to variety of ImDrawList functions, that consistency becomes more important. + The new order is also more convenient as `flags` are less frequently used than `thickness` in real code. + - As a general policy in Dear ImGui, all our flags default to 0 so ImDrawFlags_None was likely written 0 in some call sites. + - Consider adding `#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in your imconfig.h, even temporarily, to clean up legacy code. + - 2026/05/07 (1.92.8) - DrawList: changed value of `ImDrawFlags_Closed`. It was previously advertised as "always == 1" when introduced in 1.82 (2021/02), in order to facilitate backward compatibility with the legacy `bool closed` flag. + This guarantee has been removed. The bit is reserved and `AddPolyline()`, `PathStroke()` will assert when it is used. + - 2026/04/23 (1.92.8) - DrawList: obsoleted `ImDrawCallback_ResetRenderState` in favor of using `ImGui::GetPlatformIO().DrawCallback_ResetRenderState`, which is part of our new standard draw callbacks. (#9378) + - 2026/04/22 (1.92.8) - Backends: Vulkan: redesigned to use separate ImageView + Sampler instead of Combined Image Sampler. + - When registering custom textures: changed ImGui_ImplVulkan_AddTexture() signature to remove Sampler. + - When creating your own descriptor pool (instead of letting backend creates its own): need at least IMGUI_IMPL_VULKAN_MINIMUM_SAMPLED_IMAGE_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE + IMGUI_IMPL_VULKAN_MINIMUM_SAMPLER_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_SAMPLER. + - 2026/03/19 (1.92.7) - MultiSelect: renamed ImGuiMultiSelectFlags_SelectOnClick to ImGuiMultiSelectFlags_SelectOnAuto. + - 2026/02/26 (1.92.7) - Separator: fixed a legacy quirk where Separator() was submitting a zero-height item for layout purpose, even though it draws a 1-pixel separator. + The fix could affect code e.g. computing height from multiple widgets in order to allocate vertical space for a footer or multi-line status bar. (#2657, #9263) + The "Console" example had such a bug: + float footer_height = style.ItemSpacing.y + ImGui::GetFrameHeightWithSpacing(); + BeginChild("ScrollingRegion", { 0, -footer_height }); + Should be: + float footer_height = style.ItemSpacing.y + style.SeparatorSize + ImGui::GetFrameHeightWithSpacing(); + BeginChild("ScrollingRegion", { 0, -footer_height }); + When such idiom was used and assuming zero-height Separator, it is likely that in 1.92.7 the resulting window will have unexpected 1 pixel scrolling range. + - 2026/02/23 (1.92.7) - Commented out legacy signature for Combo(), ListBox(), signatures which were obsoleted in 1.90 (Nov 2023), when the getter callback type was changed. + - Old getter type: bool (*getter)(void* user_data, int idx, const char** out_text) // Set label + return bool. False replaced label with placeholder. + - New getter type: const char* (*getter)(void* user_data, int idx) // Return label or NULL/empty label if missing + - 2026/01/08 (1.92.6) - Commented out legacy names obsoleted in 1.90 (Sept 2023): 'BeginChildFrame()' --> 'BeginChild()' with 'ImGuiChildFlags_FrameStyle'. 'EndChildFrame()' --> 'EndChild()'. 'ShowStackToolWindow()' --> 'ShowIDStackToolWindow()'. 'IM_OFFSETOF()' --> 'offsetof()'. + - 2026/01/07 (1.92.6) - Popups: changed compile-time 'ImGuiPopupFlags popup_flags = 1' default value to be '= 0' for BeginPopupContextItem(), BeginPopupContextWindow(), BeginPopupContextVoid(), OpenPopupOnItemClick(). Default value has same meaning before and after. + - Refer to GitHub topic #9157 if you have any question. + - Before this version, those functions had a 'ImGuiPopupFlags popup_flags = 1' default value in their function signature. + Explicitly passing a literal 0 meant ImGuiPopupFlags_MouseButtonLeft. The default literal 1 meant ImGuiPopupFlags_MouseButtonRight. + This was introduced by a change on 2020/06/23 (1.77) while changing the signature from 'int mouse_button' to 'ImGuiPopupFlags popup_flags' and trying to preserve then-legacy behavior. + We have now changed this behavior to cleanup a very old API quirk, facilitate use by bindings, and to remove the last and error-prone non-zero default value. + Also because we deemed it extremely rare to use those helper functions with the Left mouse button! As using the LMB would generally be triggered via another widget, e.g. a Button() + a OpenPopup()/BeginPopup() call. + - Before: The default = 1 means ImGuiPopupFlags_MouseButtonRight. Explicitly passing a literal 0 means ImGuiPopupFlags_MouseButtonLeft. + - After: The default = 0 means ImGuiPopupFlags_MouseButtonRight. Explicitly passing a literal 1 also means ImGuiPopupFlags_MouseButtonRight (if legacy behavior are enabled) or will assert (if legacy behavior are disabled). + - TL;DR: if you don't want to use right mouse button for popups, always specify it explicitly using a named ImGuiPopupFlags_MouseButtonXXXX value. + Recap: + - BeginPopupContextItem("foo"); // Behavior unchanged (use Right button) + - BeginPopupContextItem("foo", ImGuiPopupFlags_MouseButtonLeft); // Behavior unchanged (use Left button) + - BeginPopupContextItem("foo", ImGuiPopupFlags_MouseButtonLeft | xxx); // Behavior unchanged (use Left button + flags) + - BeginPopupContextItem("foo", ImGuiPopupFlags_MouseButtonRight | xxx); // Behavior unchanged (use Right button + flags) + - BeginPopupContextItem("foo", 1); // Behavior unchanged (as a courtesy we legacy interpret 1 as ImGuiPopupFlags_MouseButtonRight, will assert if disabling legacy behaviors. + - BeginPopupContextItem("foo", 0); // !! Behavior changed !! Was Left button. Now will defaults to Right button! --> Use ImGuiPopupFlags_MouseButtonLeft. + - BeginPopupContextItem("foo", ImGuiPopupFlags_NoReopen); // !! Behavior changed !! Was Left button + flags. Now will defaults to Right button! --> Use ImGuiPopupFlags_MouseButtonLeft | xxx. + - 2025/12/23 (1.92.6) - Fonts: AddFontDefault() now automatically selects an embedded font between the new scalable AddFontDefaultVector() and the classic pixel-clean AddFontDefaultBitmap(). + The default selection is based on (style.FontSizeBase * FontScaleMain * FontScaleDpi) reaching a small threshold, but old codebases may not set any of them properly. As as a result, it is likely that old codebase may still default to AddFontDefaultBitmap(). + Prefer calling either based on your own logic. You can call AddFontDefaultBitmap() to ensure legacy behavior. + - 2025/12/23 (1.92.6) - Fonts: removed ImFontConfig::PixelSnapV added in 1.92 which turns out is unnecessary (and misdocumented). Post-rescale GlyphOffset is always rounded. + - 2025/12/17 (1.92.6) - Renamed helper macro IM_ARRAYSIZE() -> IM_COUNTOF(). Kept redirection/legacy name for now. + - 2025/12/11 (1.92.6) - Hashing: handling of "###" operator to reset to seed within a string identifier doesn't include the "###" characters in the output hash anymore. + - Before: GetID("Hello###World") == GetID("###World") != GetID("World") + - After: GetID("Hello###World") == GetID("###World") == GetID("World") + - This has the property of facilitating concatenating and manipulating identifiers using "###", and will allow fixing other dangling issues. + - This will invalidate hashes (stored in .ini data) for Tables and Windows that are using the "###" operators. (#713, #1698) + - 2025/11/24 (1.92.6) - Fonts: Fixed handling of `ImFontConfig::FontDataOwnedByAtlas = false` which did erroneously make a copy of the font data, essentially defeating the purpose of this flag and wasting memory. + (trivia: undetected since July 2015, this is perhaps the oldest bug in Dear ImGui history, albeit for a rarely used feature, see #9086) + HOWEVER, fixing this bug is likely to surface bugs in user code using `FontDataOwnedByAtlas = false`. + - Prior to 1.92, font data only needed to be available during the atlas->AddFontXXX() call. + - Since 1.92, font data needs to available until atlas->RemoveFont(), or more typically until a shutdown of the owning context or font atlas. + - The fact that handling of `FontDataOwnedByAtlas = false` was broken bypassed the issue altogether. + - 2025/11/06 (1.92.5) - BeginChild: commented out some legacy names which were obsoleted in 1.90.0 (Nov 2023), 1.90.9 (July 2024), 1.91.1 (August 2024): + - ImGuiChildFlags_Border --> ImGuiChildFlags_Borders + - ImGuiWindowFlags_NavFlattened --> ImGuiChildFlags_NavFlattened (moved to ImGuiChildFlags). BeginChild(name, size, 0, ImGuiWindowFlags_NavFlattened) --> BeginChild(name, size, ImGuiChildFlags_NavFlattened, 0) + - ImGuiWindowFlags_AlwaysUseWindowPadding --> ImGuiChildFlags_AlwaysUseWindowPadding (moved to ImGuiChildFlags). BeginChild(name, size, 0, ImGuiWindowFlags_AlwaysUseWindowPadding) --> BeginChild(name, size, ImGuiChildFlags_AlwaysUseWindowPadding, 0) + - 2025/11/06 (1.92.5) - Keys: commented out legacy names which were obsoleted in 1.89.0 (August 2022): + - ImGuiKey_ModCtrl --> ImGuiMod_Ctrl + - ImGuiKey_ModShift --> ImGuiMod_Shift + - ImGuiKey_ModAlt --> ImGuiMod_Alt + - ImGuiKey_ModSuper --> ImGuiMod_Super + - 2025/11/06 (1.92.5) - IO: commented out legacy io.ClearInputCharacters() obsoleted in 1.89.8 (Aug 2023). Calling io.ClearInputKeys() is enough. + - 2025/11/06 (1.92.5) - Commented out legacy SetItemAllowOverlap() obsoleted in 1.89.7: this never worked right. Use SetNextItemAllowOverlap() _before_ item instead. + - 2025/10/14 (1.92.4) - TreeNode, Selectable, Clipper: commented out legacy names which were obsoleted in 1.89.7 (July 2023) and 1.89.9 (Sept 2023); + - ImGuiTreeNodeFlags_AllowItemOverlap --> ImGuiTreeNodeFlags_AllowOverlap + - ImGuiSelectableFlags_AllowItemOverlap --> ImGuiSelectableFlags_AllowOverlap + - ImGuiListClipper::IncludeRangeByIndices() --> ImGuiListClipper::IncludeItemsByIndex() + - 2025/08/08 (1.92.2) - Backends: SDL_GPU3: Changed ImTextureID type from SDL_GPUTextureSamplerBinding* to SDL_GPUTexture*, which is more natural and easier for user to manage. If you need to change the current sampler, you can access the ImGui_ImplSDLGPU3_RenderState struct. (#8866, #8163, #7998, #7988) + - 2025/07/31 (1.92.2) - Tabs: Renamed ImGuiTabBarFlags_FittingPolicyResizeDown to ImGuiTabBarFlags_FittingPolicyShrink. Kept inline redirection enum (will obsolete). + - 2025/06/25 (1.92.0) - Layout: commented out legacy ErrorCheckUsingSetCursorPosToExtendParentBoundaries() fallback obsoleted in 1.89 (August 2022) which allowed a SetCursorPos()/SetCursorScreenPos() call WITHOUT AN ITEM + to extend parent window/cell boundaries. Replaced with assert/tooltip that would already happens if previously using IMGUI_DISABLE_OBSOLETE_FUNCTIONS.

I TRIED REALLY HARD TO KEEP THEM TO A MINIMUM, REDUCE THE AMOUNT OF INTERFERENCES, BUT INEVITABLY SOME USERS WILL BE AFFECTED. + IN ORDER TO HELP US IMPROVE THE TRANSITION PROCESS, INCL. DOCUMENTATION AND COMMENTS, PLEASE REPORT **ANY** DOUBT, CONFUSION, QUESTIONS, FEEDBACK TO: https://github.com/ocornut/imgui/issues/ + As part of the plan to reduce impact of API breaking changes, several unfinished changes/features/refactors related to font and text systems and scaling will be part of subsequent releases (1.92.1+). + If you are updating from an old version, and expecting a massive or difficult update, consider first updating to 1.91.9 to reduce the amount of changes. + - Hard to read? Refer to 'docs/Changelog.txt' for a less compact and more complete version of this! + - Fonts: **IMPORTANT**: if your app was solving the OSX/iOS Retina screen specific logical vs display scale problem by setting io.DisplayFramebufferScale (e.g. to 2.0f) + setting io.FontGlobalScale (e.g. to 1.0f/2.0f) + loading fonts at scaled sizes (e.g. size X * 2.0f): + This WILL NOT map correctly to the new system! Because font will rasterize as requested size. + - With a legacy backend (< 1.92): Instead of setting io.FontGlobalScale = 1.0f/N -> set ImFontCfg::RasterizerDensity = N. This already worked before, but is now pretty much required. + - With a new backend (1.92+): This should be all automatic. FramebufferScale is automatically used to set current font RasterizerDensity. FramebufferScale is a per-viewport property provided by backend through the Platform_GetWindowFramebufferScale() handler in 'docking' branch. + - Fonts: **IMPORTANT** on Font Sizing: Before 1.92, fonts were of a single size. They can now be dynamically sized. + - PushFont() API now has a REQUIRED size parameter. + - Before 1.92: PushFont() always used font "default" size specified in AddFont() call. It is equivalent to calling PushFont(font, font->LegacySize). + - Since 1.92: PushFont(font, 0.0f) preserve the current font size which is a shared value. + - To use old behavior: use 'ImGui::PushFont(font, font->LegacySize)' at call site. + - Kept inline single parameter function. Will obsolete. + - Fonts: **IMPORTANT** on Font Merging: + - When searching for a glyph in multiple merged fonts: we search for the FIRST font source which contains the desired glyph. + Because the user doesn't need to provide glyph ranges any more, it is possible that a glyph that you expected to fetch from a secondary/merged icon font may be erroneously fetched from the primary font. + - When searching for a glyph in multiple merged fonts: we now search for the FIRST font source which contains the desired glyph. This is technically a different behavior than before! + - e.g. If you are merging fonts you may have glyphs that you expected to load from Font Source 2 which exists in Font Source 1. + After the update and when using a new backend, those glyphs may now loaded from Font Source 1! + - We added `ImFontConfig::GlyphExcludeRanges[]` to specify ranges to exclude from a given font source: + // Add Font Source 1 but ignore ICON_MIN_FA..ICON_MAX_FA range + static ImWchar exclude_ranges[] = { ICON_MIN_FA, ICON_MAX_FA, 0 }; + ImFontConfig cfg1; + cfg1.GlyphExcludeRanges = exclude_ranges; + io.Fonts->AddFontFromFileTTF("segoeui.ttf", 0.0f, &cfg1); + // Add Font Source 2, which expects to use the range above + ImFontConfig cfg2; + cfg2.MergeMode = true; + io.Fonts->AddFontFromFileTTF("FontAwesome4.ttf", 0.0f, &cfg2); + - You can use `Metrics/Debugger->Fonts->Font->Input Glyphs Overlap Detection Tool` to see list of glyphs available in multiple font sources. This can facilitate understanding which font input is providing which glyph. + - Fonts: **IMPORTANT** on Thread Safety: + - A few functions such as font->CalcTextSizeA() were, by sheer luck (== accidentally) thread-safe even though we had never provided that guarantee. They are definitively not thread-safe anymore as new glyphs may be loaded. + - Fonts: ImFont::FontSize was removed and does not make sense anymore. ImFont::LegacySize is the size passed to AddFont(). + - Fonts: Removed support for PushFont(NULL) which was a shortcut for "default font". + - Fonts: Renamed/moved 'io.FontGlobalScale' to 'style.FontScaleMain'. + - Textures: all API functions taking a 'ImTextureID' parameter are now taking a 'ImTextureRef'. Affected functions are: ImGui::Image(), ImGui::ImageWithBg(), ImGui::ImageButton(), ImDrawList::AddImage(), ImDrawList::AddImageQuad(), ImDrawList::AddImageRounded(). + - Fonts: obsoleted ImFontAtlas::GetTexDataAsRGBA32(), GetTexDataAsAlpha8(), Build(), SetTexID(), IsBuilt() functions. The new protocol for backends to handle textures doesn't need them. Kept redirection functions (will obsolete). + - Fonts: ImFontConfig::OversampleH/OversampleV default to automatic (== 0) since v1.91.8. It is quite important you keep it automatic until we decide if we want to provide a way to express finer policy, otherwise you will likely waste texture space when using large glyphs. Note that the imgui_freetype backend doesn't use and does not need oversampling. + - Fonts: specifying glyph ranges is now unnecessary. The value of ImFontConfig::GlyphRanges[] is only useful for legacy backends. All GetGlyphRangesXXXX() functions are now marked obsolete: GetGlyphRangesDefault(), GetGlyphRangesGreek(), GetGlyphRangesKorean(), GetGlyphRangesJapanese(), GetGlyphRangesChineseSimplifiedCommon(), GetGlyphRangesChineseFull(), GetGlyphRangesCyrillic(), GetGlyphRangesThai(), GetGlyphRangesVietnamese(). + - Fonts: removed ImFontAtlas::TexDesiredWidth to enforce a texture width. (#327) + - Fonts: if you create and manage ImFontAtlas instances yourself (instead of relying on ImGuiContext to create one), you'll need to call ImFontAtlasUpdateNewFrame() yourself. An assert will trigger if you don't. + - Fonts: obsolete ImGui::SetWindowFontScale() which is not useful anymore. Prefer using 'PushFont(NULL, style.FontSizeBase * factor)' or to manipulate other scaling factors. + - Fonts: obsoleted ImFont::Scale which is not useful anymore. + - Fonts: generally reworked Internals of ImFontAtlas and ImFont. While in theory a vast majority of users shouldn't be affected, some use cases or extensions might be. Among other things: + - ImDrawCmd::TextureId has been changed to ImDrawCmd::TexRef. + - ImFontAtlas::TexID has been changed to ImFontAtlas::TexRef. + - ImFontAtlas::ConfigData[] has been renamed to ImFontAtlas::Sources[] + - ImFont::ConfigData[], ConfigDataCount has been renamed to Sources[], SourceCount. + - Each ImFont has a number of ImFontBaked instances corresponding to actively used sizes. ImFont::GetFontBaked(size) retrieves the one for a given size. + - Fields moved from ImFont to ImFontBaked: IndexAdvanceX[], Glyphs[], Ascent, Descent, FindGlyph(), FindGlyphNoFallback(), GetCharAdvance(). + - Fields moved from ImFontAtlas to ImFontAtlas->Tex: ImFontAtlas::TexWidth => TexData->Width, ImFontAtlas::TexHeight => TexData->Height, ImFontAtlas::TexPixelsAlpha8/TexPixelsRGBA32 => TexData->GetPixels(). + - Widget code may use ImGui::GetFontBaked() instead of ImGui::GetFont() to access font data for current font at current font size (and you may use font->GetFontBaked(size) to access it for any other size.) + - Fonts: (users of imgui_freetype): renamed ImFontAtlas::FontBuilderFlags to ImFontAtlas::FontLoaderFlags. Renamed ImFontConfig::FontBuilderFlags to ImFontConfig::FontLoaderFlags. Renamed ImGuiFreeTypeBuilderFlags to ImGuiFreeTypeLoaderFlags. + If you used runtime imgui_freetype selection rather than the default IMGUI_ENABLE_FREETYPE compile-time option: Renamed/reworked ImFontBuilderIO into ImFontLoader. Renamed ImGuiFreeType::GetBuilderForFreeType() to ImGuiFreeType::GetFontLoader(). + - old: io.Fonts->FontBuilderIO = ImGuiFreeType::GetBuilderForFreeType() + - new: io.Fonts->FontLoader = ImGuiFreeType::GetFontLoader() + - new: io.Fonts->SetFontLoader(ImGuiFreeType::GetFontLoader()) to change dynamically at runtime [from 1.92.1] + - Fonts: (users of custom rectangles, see #8466): Renamed AddCustomRectRegular() to AddCustomRect(). Added GetCustomRect() as a replacement for GetCustomRectByIndex() + CalcCustomRectUV(). + - The output type of GetCustomRect() is now ImFontAtlasRect, which include UV coordinates. X->x, Y->y, Width->w, Height->h. + - old: + const ImFontAtlasCustomRect* r = atlas->GetCustomRectByIndex(custom_rect_id); + ImVec2 uv0, uv1; + atlas->GetCustomRectUV(r, &uv0, &uv1); + ImGui::Image(atlas->TexRef, ImVec2(r->w, r->h), uv0, uv1); + - new; + ImFontAtlasRect r; + atlas->GetCustomRect(custom_rect_id, &r); + ImGui::Image(atlas->TexRef, ImVec2(r.w, r.h), r.uv0, r.uv1); + - We added a redirecting typedef but haven't attempted to magically redirect the field names, as this API is rarely used and the fix is simple. + - Obsoleted AddCustomRectFontGlyph() as the API does not make sense for scalable fonts. Kept existing function which uses the font "default size" (Sources[0]->LegacySize). Added a helper AddCustomRectFontGlyphForSize() which is immediately marked obsolete, but can facilitate transitioning old code. + - Prefer adding a font source (ImFontConfig) using a custom/procedural loader. + - DrawList: Renamed ImDrawList::PushTextureID()/PopTextureID() to PushTexture()/PopTexture(). + - Backends: removed ImGui_ImplXXXX_CreateFontsTexture()/ImGui_ImplXXXX_DestroyFontsTexture() for all backends that had them. They should not be necessary any more. + - 2025/05/23 (1.92.0) - Fonts: changed ImFont::CalcWordWrapPositionA() to ImFont::CalcWordWrapPosition() + - old: const char* ImFont::CalcWordWrapPositionA(float scale, const char* text, ....); + - new: const char* ImFont::CalcWordWrapPosition (float size, const char* text, ....); + The leading 'float scale' parameters was changed to 'float size'. This was necessary as 'scale' is assuming standard font size which is a concept we aim to eliminate in an upcoming update. Kept inline redirection function. + - 2025/05/15 (1.92.0) - TreeNode: renamed ImGuiTreeNodeFlags_NavLeftJumpsBackHere to ImGuiTreeNodeFlags_NavLeftJumpsToParent for clarity. Kept inline redirection enum (will obsolete). + - 2025/05/15 (1.92.0) - Commented out PushAllowKeyboardFocus()/PopAllowKeyboardFocus() which was obsoleted in 1.89.4. Use PushItemFlag(ImGuiItemFlags_NoTabStop, !tab_stop)/PopItemFlag() instead. (#3092) + - 2025/05/15 (1.92.0) - Commented out ImGuiListClipper::ForceDisplayRangeByIndices() which was obsoleted in 1.89.6. Use ImGuiListClipper::IncludeItemsByIndex() instead. + - 2025/03/05 (1.91.9) - BeginMenu(): Internals: reworked mangling of menu windows to use "###Menu_00" etc. instead of "##Menu_00", allowing them to also store the menu name before it. This shouldn't affect code unless directly accessing menu window from their mangled name. + - 2025/04/16 (1.91.9) - Internals: RenderTextEllipsis() function removed the 'float clip_max_x' parameter directly preceding 'float ellipsis_max_x'. Values were identical for a vast majority of users. (#8387) + - 2025/02/27 (1.91.9) - Image(): removed 'tint_col' and 'border_col' parameter from Image() function. Added ImageWithBg() replacement. (#8131, #8238) + - old: void Image (ImTextureID tex_id, ImVec2 image_size, ImVec2 uv0 = (0,0), ImVec2 uv1 = (1,1), ImVec4 tint_col = (1,1,1,1), ImVec4 border_col = (0,0,0,0)); + - new: void Image (ImTextureID tex_id, ImVec2 image_size, ImVec2 uv0 = (0,0), ImVec2 uv1 = (1,1)); + - new: void ImageWithBg(ImTextureID tex_id, ImVec2 image_size, ImVec2 uv0 = (0,0), ImVec2 uv1 = (1,1), ImVec4 bg_col = (0,0,0,0), ImVec4 tint_col = (1,1,1,1)); + - TL;DR: 'border_col' had misleading side-effect on layout, 'bg_col' was missing, parameter order couldn't be consistent with ImageButton(). + - new behavior always use ImGuiCol_Border color + style.ImageBorderSize / ImGuiStyleVar_ImageBorderSize. + - old behavior altered border size (and therefore layout) based on border color's alpha, which caused variety of problems + old behavior a fixed 1.0f for border size which was not tweakable. + - kept legacy signature (will obsolete), which mimics the old behavior, but uses Max(1.0f, style.ImageBorderSize) when border_col is specified. + - added ImageWithBg() function which has both 'bg_col' (which was missing) and 'tint_col'. It was impossible to add 'bg_col' to Image() with a parameter order consistent with other functions, so we decided to remove 'tint_col' and introduce ImageWithBg(). + - 2025/02/25 (1.91.9) - internals: fonts: ImFontAtlas::ConfigData[] has been renamed to ImFontAtlas::Sources[]. ImFont::ConfigData[], ConfigDataCount has been renamed to Sources[], SourcesCount. + - 2025/02/06 (1.91.9) - renamed ImFontConfig::GlyphExtraSpacing.x to ImFontConfig::GlyphExtraAdvanceX. + - 2025/01/22 (1.91.8) - removed ImGuiColorEditFlags_AlphaPreview (made value 0): it is now the default behavior. + prior to 1.91.8: alpha was made opaque in the preview by default _unless_ using ImGuiColorEditFlags_AlphaPreview. We now display the preview as transparent by default. You can use ImGuiColorEditFlags_AlphaOpaque to use old behavior. + the new flags (ImGuiColorEditFlags_AlphaOpaque, ImGuiColorEditFlags_AlphaNoBg + existing ImGuiColorEditFlags_AlphaPreviewHalf) may be combined better and allow finer controls: + - 2025/01/14 (1.91.7) - renamed ImGuiTreeNodeFlags_SpanTextWidth to ImGuiTreeNodeFlags_SpanLabelWidth for consistency with other names. Kept redirection enum (will obsolete). (#6937) + - 2024/11/27 (1.91.6) - changed CRC32 table from CRC32-adler to CRC32c polynomial in order to be compatible with the result of SSE 4.2 instructions. + As a result, old .ini data may be partially lost (docking and tables information particularly). + Because some users have crafted and storing .ini data as a way to workaround limitations of the docking API, we are providing a '#define IMGUI_USE_LEGACY_CRC32_ADLER' compile-time option to keep using old CRC32 tables if you cannot afford invalidating old .ini data. + - 2024/11/06 (1.91.5) - commented/obsoleted out pre-1.87 IO system (equivalent to using IMGUI_DISABLE_OBSOLETE_KEYIO or IMGUI_DISABLE_OBSOLETE_FUNCTIONS before) + - io.KeyMap[] and io.KeysDown[] are removed (obsoleted February 2022). + - io.NavInputs[] and ImGuiNavInput are removed (obsoleted July 2022). + - GetKeyIndex() is removed (obsoleted March 2022). The indirection is now unnecessary. + - pre-1.87 backends are not supported: + - backends need to call io.AddKeyEvent(), io.AddMouseEvent() instead of writing to io.KeysDown[], io.MouseDown[] fields. + - backends need to call io.AddKeyAnalogEvent() for gamepad values instead of writing to io.NavInputs[] fields. + - for more reference: + - read 1.87 and 1.88 part of this section or read Changelog for 1.87 and 1.88. + - read https://github.com/ocornut/imgui/issues/4921 + - if you have trouble updating a very old codebase using legacy backend-specific key codes: consider updating to 1.91.4 first, then #define IMGUI_DISABLE_OBSOLETE_KEYIO, then update to latest. + - obsoleted ImGuiKey_COUNT (it is unusually error-prone/misleading since valid keys don't start at 0). probably use ImGuiKey_NamedKey_BEGIN/ImGuiKey_NamedKey_END? + - fonts: removed const qualifiers from most font functions in prevision for upcoming font improvements. + - 2024/10/18 (1.91.4) - renamed ImGuiCol_NavHighlight to ImGuiCol_NavCursor (for consistency with newly exposed and reworked features). Kept inline redirection enum (will obsolete). + - 2024/10/14 (1.91.4) - moved ImGuiConfigFlags_NavEnableSetMousePos to standalone io.ConfigNavMoveSetMousePos bool. + moved ImGuiConfigFlags_NavNoCaptureKeyboard to standalone io.ConfigNavCaptureKeyboard bool (note the inverted value!). + kept legacy names (will obsolete) + code that copies settings once the first time. Dynamically changing the old value won't work. Switch to using the new value! + - 2024/10/10 (1.91.4) - the typedef for ImTextureID now defaults to ImU64 instead of void*. (#1641) + this removes the requirement to redefine it for backends which are e.g. storing descriptor sets or other 64-bits structures when building on 32-bits archs. It therefore simplify various building scripts/helpers. + you may have compile-time issues if you were casting to 'void*' instead of 'ImTextureID' when passing your types to functions taking ImTextureID values, e.g. ImGui::Image(). + in doubt it is almost always better to do an intermediate intptr_t cast, since it allows casting any pointer/integer type without warning: + - May warn: ImGui::Image((void*)MyTextureData, ...); + - May warn: ImGui::Image((void*)(intptr_t)MyTextureData, ...); + - Won't warn: ImGui::Image((ImTextureID)(intptr_t)MyTextureData, ...); + - note that you can always define ImTextureID to be your own high-level structures (with dedicated constructors) if you like. + - 2024/10/03 (1.91.3) - drags: treat v_min==v_max as a valid clamping range when != 0.0f. Zero is a still special value due to legacy reasons, unless using ImGuiSliderFlags_ClampZeroRange. (#7968, #3361, #76) + - drags: extended behavior of ImGuiSliderFlags_AlwaysClamp to include _ClampZeroRange. It considers v_min==v_max==0.0f as a valid clamping range (aka edits not allowed). + although unlikely, it you wish to only clamp on text input but want v_min==v_max==0.0f to mean unclamped drags, you can use _ClampOnInput instead of _AlwaysClamp. (#7968, #3361, #76) + - 2024/09/10 (1.91.2) - internals: using multiple overlaid ButtonBehavior() with same ID will now have io.ConfigDebugHighlightIdConflicts=true feature emit a warning. (#8030) + it was one of the rare case where using same ID is legal. workarounds: (1) use single ButtonBehavior() call with multiple _MouseButton flags, or (2) surround the calls with PushItemFlag(ImGuiItemFlags_AllowDuplicateId, true); ... PopItemFlag() + - 2024/08/23 (1.91.1) - renamed ImGuiChildFlags_Border to ImGuiChildFlags_Borders for consistency. kept inline redirection flag. + - 2024/08/22 (1.91.1) - moved some functions from ImGuiIO to ImGuiPlatformIO structure: + - io.GetClipboardTextFn -> platform_io.Platform_GetClipboardTextFn + changed 'void* user_data' to 'ImGuiContext* ctx'. Pull your user data from platform_io.ClipboardUserData. + - io.SetClipboardTextFn -> platform_io.Platform_SetClipboardTextFn + same as above line. + - io.PlatformOpenInShellFn -> platform_io.Platform_OpenInShellFn (#7660) + - io.PlatformSetImeDataFn -> platform_io.Platform_SetImeDataFn + - io.PlatformLocaleDecimalPoint -> platform_io.Platform_LocaleDecimalPoint (#7389, #6719, #2278) + - access those via GetPlatformIO() instead of GetIO(). + some were introduced very recently and often automatically setup by core library and backends, so for those we are exceptionally not maintaining a legacy redirection symbol. + - commented the old ImageButton() signature obsoleted in 1.89 (~August 2022). As a reminder: + - old ImageButton() before 1.89 used ImTextureId as item id (created issue with e.g. multiple buttons in same scope, transient texture id values, opaque computation of ID) + - new ImageButton() since 1.89 requires an explicit 'const char* str_id' + - old ImageButton() before 1.89 had frame_padding' override argument. + - new ImageButton() since 1.89 always use style.FramePadding, which you can freely override with PushStyleVar()/PopStyleVar(). + - 2024/07/25 (1.91.0) - obsoleted GetContentRegionMax(), GetWindowContentRegionMin() and GetWindowContentRegionMax(). (see #7838 on GitHub for more info) + you should never need those functions. you can do everything with GetCursorScreenPos() and GetContentRegionAvail() in a more simple way. + - instead of: GetWindowContentRegionMax().x - GetCursorPos().x + - you can use: GetContentRegionAvail().x + - instead of: GetWindowContentRegionMax().x + GetWindowPos().x + - you can use: GetCursorScreenPos().x + GetContentRegionAvail().x // when called from left edge of window + - instead of: GetContentRegionMax() + - you can use: GetContentRegionAvail() + GetCursorScreenPos() - GetWindowPos() // right edge in local coordinates + - instead of: GetWindowContentRegionMax().x - GetWindowContentRegionMin().x + - you can use: GetContentRegionAvail() // when called from left edge of window + - 2024/07/15 (1.91.0) - renamed ImGuiSelectableFlags_DontClosePopups to ImGuiSelectableFlags_NoAutoClosePopups. (#1379, #1468, #2200, #4936, #5216, #7302, #7573) + (internals: also renamed ImGuiItemFlags_SelectableDontClosePopup into ImGuiItemFlags_AutoClosePopups with inverted behaviors) + - 2024/07/15 (1.91.0) - obsoleted PushButtonRepeat()/PopButtonRepeat() in favor of using new PushItemFlag(ImGuiItemFlags_ButtonRepeat, ...)/PopItemFlag(). + - 2024/07/02 (1.91.0) - commented out obsolete ImGuiModFlags (renamed to ImGuiKeyChord in 1.89). (#4921, #456) + - commented out obsolete ImGuiModFlags_XXX values (renamed to ImGuiMod_XXX in 1.89). (#4921, #456) + - ImGuiModFlags_Ctrl -> ImGuiMod_Ctrl, ImGuiModFlags_Shift -> ImGuiMod_Shift etc. + - 2024/07/02 (1.91.0) - IO, IME: renamed platform IME hook and added explicit context for consistency and future-proofness. + - old: io.SetPlatformImeDataFn(ImGuiViewport* viewport, ImGuiPlatformImeData* data); + - new: io.PlatformSetImeDataFn(ImGuiContext* ctx, ImGuiViewport* viewport, ImGuiPlatformImeData* data); + - 2024/06/21 (1.90.9) - BeginChild: added ImGuiChildFlags_NavFlattened as a replacement for the window flag ImGuiWindowFlags_NavFlattened: the feature only ever made sense for BeginChild() anyhow. + - old: BeginChild("Name", size, 0, ImGuiWindowFlags_NavFlattened); + - new: BeginChild("Name", size, ImGuiChildFlags_NavFlattened, 0); + - 2024/06/21 (1.90.9) - io: ClearInputKeys() (first exposed in 1.89.8) doesn't clear mouse data, newly added ClearInputMouse() does. + - 2024/06/20 (1.90.9) - renamed ImGuiDragDropFlags_SourceAutoExpirePayload to ImGuiDragDropFlags_PayloadAutoExpire. + - 2024/06/18 (1.90.9) - style: renamed ImGuiCol_TabActive -> ImGuiCol_TabSelected, ImGuiCol_TabUnfocused -> ImGuiCol_TabDimmed, ImGuiCol_TabUnfocusedActive -> ImGuiCol_TabDimmedSelected. + - 2024/06/10 (1.90.9) - removed old nested structure: renaming ImGuiStorage::ImGuiStoragePair type to ImGuiStoragePair (simpler for many languages). + - 2024/06/06 (1.90.8) - reordered ImGuiInputTextFlags values. This should not be breaking unless you are using generated headers that have values not matching the main library. + - 2024/06/06 (1.90.8) - removed 'ImGuiButtonFlags_MouseButtonDefault_ = ImGuiButtonFlags_MouseButtonLeft', was mostly unused and misleading. + - 2024/05/27 (1.90.7) - commented out obsolete symbols marked obsolete in 1.88 (May 2022): + - old: CaptureKeyboardFromApp(bool) + - new: SetNextFrameWantCaptureKeyboard(bool) + - old: CaptureMouseFromApp(bool) + - new: SetNextFrameWantCaptureMouse(bool) + - 2024/05/22 (1.90.7) - inputs (internals): renamed ImGuiKeyOwner_None to ImGuiKeyOwner_NoOwner, to make use more explicit and reduce confusion with the default it is a non-zero value and cannot be the default value (never made public, but disclosing as I expect a few users caught on owner-aware inputs). + - inputs (internals): renamed ImGuiInputFlags_RouteGlobalLow -> ImGuiInputFlags_RouteGlobal, ImGuiInputFlags_RouteGlobal -> ImGuiInputFlags_RouteGlobalOverFocused, ImGuiInputFlags_RouteGlobalHigh -> ImGuiInputFlags_RouteGlobalHighest. + - inputs (internals): Shortcut(), SetShortcutRouting(): swapped last two parameters order in function signatures: + - old: Shortcut(ImGuiKeyChord key_chord, ImGuiID owner_id = 0, ImGuiInputFlags flags = 0); + - new: Shortcut(ImGuiKeyChord key_chord, ImGuiInputFlags flags = 0, ImGuiID owner_id = 0); + - inputs (internals): owner-aware versions of IsKeyPressed(), IsKeyChordPressed(), IsMouseClicked(): swapped last two parameters order in function signatures. + - old: IsKeyPressed(ImGuiKey key, ImGuiID owner_id, ImGuiInputFlags flags = 0); + - new: IsKeyPressed(ImGuiKey key, ImGuiInputFlags flags, ImGuiID owner_id = 0); + - old: IsMouseClicked(ImGuiMouseButton button, ImGuiID owner_id, ImGuiInputFlags flags = 0); + - new: IsMouseClicked(ImGuiMouseButton button, ImGuiInputFlags flags, ImGuiID owner_id = 0); + for various reasons those changes makes sense. They are being made because making some of those API public. + only past users of imgui_internal.h with the extra parameters will be affected. Added asserts for valid flags in various functions to detect _some_ misuses, BUT NOT ALL. + - 2024/05/16 (1.90.7) - inputs: on macOS X, Cmd and Ctrl keys are now automatically swapped by io.AddKeyEvent() as this naturally align with how macOS X uses those keys. + - it shouldn't really affect you unless you had custom shortcut swapping in place for macOS X apps. + - removed ImGuiMod_Shortcut which was previously dynamically remapping to Ctrl or Cmd/Super. It is now unnecessary to specific cross-platform idiomatic shortcuts. (#2343, #4084, #5923, #456) + - 2024/05/14 (1.90.7) - backends: SDL_Renderer2 and SDL_Renderer3 backend now take a SDL_Renderer* in their RenderDrawData() functions. + - 2024/04/18 (1.90.6) - TreeNode: Fixed a layout inconsistency when using an empty/hidden label followed by a SameLine() call. (#7505, #282) + - old: TreeNode("##Hidden"); SameLine(); Text("Hello"); // <-- This was actually incorrect! BUT appeared to look ok with the default style where ItemSpacing.x == FramePadding.x * 2 (it didn't look aligned otherwise). + - new: TreeNode("##Hidden"); SameLine(0, 0); Text("Hello"); // <-- This is correct for all styles values. + with the fix, IF you were successfully using TreeNode("")+SameLine(); you will now have extra spacing between your TreeNode and the following item. + You'll need to change the SameLine() call to SameLine(0,0) to remove this extraneous spacing. This seemed like the more sensible fix that's not making things less consistent. + (Note: when using this idiom you are likely to also use ImGuiTreeNodeFlags_SpanAvailWidth). + - 2024/03/18 (1.90.5) - merged the radius_x/radius_y parameters in ImDrawList::AddEllipse(), AddEllipseFilled() and PathEllipticalArcTo() into a single ImVec2 parameter. Exceptionally, because those functions were added in 1.90, we are not adding inline redirection functions. The transition is easy and should affect few users. (#2743, #7417) + - 2024/03/08 (1.90.5) - inputs: more formally obsoleted GetKeyIndex() when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is set. It has been unnecessary and a no-op since 1.87 (it returns the same value as passed when used with a 1.87+ backend using io.AddKeyEvent() function). (#4921) + - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) -> use IsKeyPressed(ImGuiKey_XXX) + - 2024/01/15 (1.90.2) - commented out obsolete ImGuiIO::ImeWindowHandle marked obsolete in 1.87, favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'. + - 2023/12/19 (1.90.1) - commented out obsolete ImGuiKey_KeyPadEnter redirection to ImGuiKey_KeypadEnter. + - 2023/11/06 (1.90.1) - removed CalcListClipping() marked obsolete in 1.86.

Use ImGuiHoveredFlags_AllowWhenOverlappedByItem to revert to old behavior. + - 2023/06/28 (1.89.7) - overlapping items: Selectable and TreeNode don't allow overlap when active so overlapping widgets won't appear as hovered. While this fixes a common small visual issue, it also means that calling IsItemHovered() after a non-reactive elements - e.g. Text() - overlapping an active one may fail if you don't use IsItemHovered(ImGuiHoveredFlags_AllowWhenBlockedByActiveItem). (#6610) + - 2023/06/20 (1.89.7) - moved io.HoverDelayShort/io.HoverDelayNormal to style.HoverDelayShort/style.HoverDelayNormal.

NULL/nullptr is ok but require cast, e.g. TreePush((void*)nullptr); + - 2022/09/05 (1.89) - commented out redirecting functions/enums names that were marked obsolete in 1.77 and 1.78 (June 2020): + - DragScalar(), DragScalarN(), DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(): For old signatures ending with (..., const char* format, float power = 1.0f) -> use (..., format ImGuiSliderFlags_Logarithmic) if power != 1.0f. + - SliderScalar(), SliderScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(): For old signatures ending with (..., const char* format, float power = 1.0f) -> use (..., format ImGuiSliderFlags_Logarithmic) if power != 1.0f. + - BeginPopupContextWindow(const char*, ImGuiMouseButton, bool) -> use BeginPopupContextWindow(const char*, ImGuiPopupFlags) + - 2022/09/02 (1.89) - obsoleted using SetCursorPos()/SetCursorScreenPos() to extend parent window/cell boundaries. + this relates to when moving the cursor position beyond current boundaries WITHOUT submitting an item. + - previously this would make the window content size ~200x200: + Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + End(); + - instead, please submit an item: + Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + Dummy(ImVec2(0,0)) + End(); + - alternative: + Begin(...) + Dummy(ImVec2(200,200)) + End(); + - content size is now only extended when submitting an item! + - with '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' this will now be detected and assert. + - without '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' this will silently be fixed until we obsolete it. + - 2022/08/03 (1.89) - changed signature of ImageButton() function. Kept redirection function (will obsolete). + - added 'const char* str_id' parameter + removed 'int frame_padding = -1' parameter. + - old signature: bool ImageButton(ImTextureID tex_id, ImVec2 size, ImVec2 uv0 = ImVec2(0,0), ImVec2 uv1 = ImVec2(1,1), int frame_padding = -1, ImVec4 bg_col = ImVec4(0,0,0,0), ImVec4 tint_col = ImVec4(1,1,1,1)); + - used the ImTextureID value to create an ID. This was inconsistent with other functions, led to ID conflicts, and caused problems with engines using transient ImTextureID values. + - had a FramePadding override which was inconsistent with other functions and made the already-long signature even longer. + - new signature: bool ImageButton(const char* str_id, ImTextureID tex_id, ImVec2 size, ImVec2 uv0 = ImVec2(0,0), ImVec2 uv1 = ImVec2(1,1), ImVec4 bg_col = ImVec4(0,0,0,0), ImVec4 tint_col = ImVec4(1,1,1,1)); + - requires an explicit identifier.

Kept inline redirection enums (will obsolete). This was never used in public API functions but technically present in imgui.h and ImGuiIO. + - 2022/01/20 (1.87) - inputs: reworded gamepad IO. + - Backend writing to io.NavInputs[] -> backend should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values. + - 2022/01/19 (1.87) - sliders, drags: removed support for legacy arithmetic operators (+,+-,*,/) when inputting text.

Removed io.KeyMap[], io.KeysDown[] in favor of calling io.AddKeyEvent(), ImGui::IsKeyDown(). Removed GetKeyIndex(), now unnecessary. All IsKeyXXX() functions now take ImGuiKey values. All features are still functional until IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Read Changelog and Release Notes for details. + - IsKeyPressed(MY_NATIVE_KEY_XXX) -> use IsKeyPressed(ImGuiKey_XXX) + - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) -> use IsKeyPressed(ImGuiKey_XXX) + - Backend writing to io.KeyMap[],io.KeysDown[] -> backend should call io.AddKeyEvent() (+ call io.SetKeyEventNativeData() if you want legacy user code to still function with legacy key codes). + - Backend writing to io.KeyCtrl, io.KeyShift.. -> backend should call io.AddKeyEvent() with ImGuiMod_XXX values. *IF YOU PULLED CODE BETWEEN 2021/01/10 and 2021/01/27: We used to have a io.AddKeyModsEvent() function which was now replaced by io.AddKeyEvent() with ImGuiMod_XXX values.* + - one case won't work with backward compatibility: if your custom backend used ImGuiKey as mock native indices (e.g. "io.KeyMap[ImGuiKey_A] = ImGuiKey_A") because those values are now larger than the legacy KeyDown[] array. Will assert. + - inputs: added ImGuiKey_ModCtrl/ImGuiKey_ModShift/ImGuiKey_ModAlt/ImGuiKey_ModSuper values to submit keyboard modifiers using io.AddKeyEvent(), instead of writing directly to io.KeyCtrl, io.KeyShift, io.KeyAlt, io.KeySuper. + - 2022/01/05 (1.87) - inputs: renamed ImGuiKey_KeyPadEnter to ImGuiKey_KeypadEnter to align with new symbols. Kept redirection enum. + - 2022/01/05 (1.87) - removed io.ImeSetInputScreenPosFn() in favor of more flexible io.SetPlatformImeDataFn(). Removed 'void* io.ImeWindowHandle' in favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'. + - 2022/01/01 (1.87) - commented out redirecting functions/enums names that were marked obsolete in 1.69, 1.70, 1.71, 1.72 (March-July 2019) + - ImGui::SetNextTreeNodeOpen() -> use ImGui::SetNextItemOpen() + - ImGui::GetContentRegionAvailWidth() -> use ImGui::GetContentRegionAvail().x + - ImGui::TreeAdvanceToLabelPos() -> use ImGui::SetCursorPosX(ImGui::GetCursorPosX() + ImGui::GetTreeNodeToLabelSpacing()); + - ImFontAtlas::CustomRect -> use ImFontAtlasCustomRect + - ImGuiColorEditFlags_RGB/HSV/HEX -> use ImGuiColorEditFlags_DisplayRGB/HSV/Hex + - 2021/12/20 (1.86) - backends: removed obsolete Marmalade backend (imgui_impl_marmalade.cpp) + example. Find last supported version at https://github.com/ocornut/imgui/wiki/Bindings + - 2021/11/04 (1.86) - removed CalcListClipping() function. Prefer using ImGuiListClipper which can return non-contiguous ranges. Please open an issue if you think you really need this function. + - 2021/08/23 (1.85) - removed GetWindowContentRegionWidth() function. keep inline redirection helper. can use 'GetWindowContentRegionMax().x - GetWindowContentRegionMin().x' instead for generally 'GetContentRegionAvail().x' is more useful. + - 2021/07/26 (1.84) - commented out redirecting functions/enums names that were marked obsolete in 1.67 and 1.69 (March 2019): + - ImGui::GetOverlayDrawList() -> use ImGui::GetForegroundDrawList() + - ImFont::GlyphRangesBuilder -> use ImFontGlyphRangesBuilder + - 2021/05/19 (1.83) - backends: obsoleted direct access to ImDrawCmd::TextureId in favor of calling ImDrawCmd::GetTexID(). + - if you are using official backends from the source tree: you have nothing to do. + - if you have copied old backend code or using your own: change access to draw_cmd->TextureId to draw_cmd->GetTexID(). + - 2021/03/12 (1.82) - upgraded ImDrawList::AddRect(), AddRectFilled(), PathRect() to use ImDrawFlags instead of ImDrawCornersFlags. + - ImDrawCornerFlags_TopLeft -> use ImDrawFlags_RoundCornersTopLeft + - ImDrawCornerFlags_BotRight -> use ImDrawFlags_RoundCornersBottomRight + - ImDrawCornerFlags_None -> use ImDrawFlags_RoundCornersNone etc. + flags now sanely defaults to 0 instead of 0x0F, consistent with all other flags in the API. + breaking: the default with rounding > 0.0f is now "round all corners" vs old implicit "round no corners": + - rounding == 0.0f + flags == 0 --> meant no rounding --> unchanged (common use) + - rounding > 0.0f + flags != 0 --> meant rounding --> unchanged (common use) + - rounding == 0.0f + flags != 0 --> meant no rounding --> unchanged (unlikely use) + - rounding > 0.0f + flags == 0 --> meant no rounding --> BREAKING (unlikely use): will now round all corners --> use ImDrawFlags_RoundCornersNone or rounding == 0.0f. + this ONLY matters for hard coded use of 0 + rounding > 0.0f. Use of named ImDrawFlags_RoundCornersNone (new) or ImDrawCornerFlags_None (old) are ok. + the old ImDrawCornersFlags used awkward default values of ~0 or 0xF (4 lower bits set) to signify "round all corners" and we sometimes encouraged using them as shortcuts. + legacy path still support use of hard coded ~0 or any value from 0x1 or 0xF. They will behave the same with legacy paths enabled (will assert otherwise). + - 2021/03/11 (1.82) - removed redirecting functions/enums names that were marked obsolete in 1.66 (September 2018): + - ImGui::SetScrollHere() -> use ImGui::SetScrollHereY() + - 2021/03/11 (1.82) - clarified that ImDrawList::PathArcTo(), ImDrawList::PathArcToFast() won't render with radius < 0.0f. Previously it sorts of accidentally worked but would generally lead to counter-clockwise paths and have an effect on anti-aliasing. + - 2021/03/10 (1.82) - upgraded ImDrawList::AddPolyline() and PathStroke() "bool closed" parameter to "ImDrawFlags flags". The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future. + - 2021/02/22 (1.82) - (*undone in 1.84*) win32+mingw: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly disable those default functions for MinGW. MinGW users should: either link with -limm32, either set their imconfig file with '#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS'. + - 2021/02/17 (1.82) - renamed rarely used style.CircleSegmentMaxError (old default = 1.60f) to style.CircleTessellationMaxError (new default = 0.30f) as the meaning of the value changed. + - 2021/02/03 (1.81) - renamed ListBoxHeader(const char* label, ImVec2 size) to BeginListBox().

Kept inline redirection function (will obsolete). + - renamed ListBoxFooter() to EndListBox(). Kept inline redirection function (will obsolete). + - 2021/01/26 (1.81) - removed ImGuiFreeType::BuildFontAtlas(). Kept inline redirection function. Prefer using '#define IMGUI_ENABLE_FREETYPE', but there's a runtime selection path available too. The shared extra flags parameters (very rarely used) are now stored in ImFontAtlas::FontBuilderFlags. + - renamed ImFontConfig::RasterizerFlags (used by FreeType) to ImFontConfig::FontBuilderFlags. + - renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API. + - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.63 (August 2018): + - ImGui::IsItemDeactivatedAfterChange() -> use ImGui::IsItemDeactivatedAfterEdit(). + - ImGuiCol_ModalWindowDarkening -> use ImGuiCol_ModalWindowDimBg + - ImGuiInputTextCallback -> use ImGuiTextEditCallback + - ImGuiInputTextCallbackData -> use ImGuiTextEditCallbackData + - 2020/12/21 (1.80) - renamed ImDrawList::AddBezierCurve() to AddBezierCubic(), and PathBezierCurveTo() to PathBezierCubicCurveTo(). Kept inline redirection function (will obsolete). + - 2020/12/04 (1.80) - added imgui_tables.cpp file! Manually constructed project files will need the new file added! + - 2020/11/18 (1.80) - renamed undocumented/internals ImGuiColumnsFlags_* to ImGuiOldColumnFlags_* in prevision of incoming Tables API. + - 2020/11/03 (1.80) - renamed io.ConfigWindowsMemoryCompactTimer to io.ConfigMemoryCompactTimer as the feature will apply to other data structures + - 2020/10/14 (1.80) - backends: moved all backends files (imgui_impl_XXXX.cpp, imgui_impl_XXXX.h) from examples/ to backends/. + - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.60 (April 2018): + - io.RenderDrawListsFn pointer -> use ImGui::GetDrawData() value and call the render function of your backend + - ImGui::IsAnyWindowFocused() -> use ImGui::IsWindowFocused(ImGuiFocusedFlags_AnyWindow) + - ImGui::IsAnyWindowHovered() -> use ImGui::IsWindowHovered(ImGuiHoveredFlags_AnyWindow) + - ImGuiStyleVar_Count_ -> use ImGuiStyleVar_COUNT + - ImGuiMouseCursor_Count_ -> use ImGuiMouseCursor_COUNT + - removed redirecting functions names that were marked obsolete in 1.61 (May 2018): + - InputFloat (... int decimal_precision ...) -> use InputFloat (... const char* format ...) with format = "%.Xf" where X is your value for decimal_precision. + - same for InputFloat2()/InputFloat3()/InputFloat4() variants taking a `int decimal_precision` parameter. + - 2020/10/05 (1.79) - removed ImGuiListClipper: Renamed constructor parameters which created an ambiguous alternative to using the ImGuiListClipper::Begin() function, with misleading edge cases (note: imgui_memory_editor <0.40 from imgui_club/ used this old clipper API. Update your copy if needed). + - 2020/09/25 (1.79) - renamed ImGuiSliderFlags_ClampOnInput to ImGuiSliderFlags_AlwaysClamp. Kept redirection enum (will obsolete sooner because previous name was added recently). + - 2020/09/25 (1.79) - renamed style.TabMinWidthForUnselectedCloseButton to style.TabMinWidthForCloseButton. + - 2020/09/21 (1.79) - renamed OpenPopupContextItem() back to OpenPopupOnItemClick(), reverting the change from 1.77. For varieties of reason this is more self-explanatory. + - 2020/09/21 (1.79) - removed return value from OpenPopupOnItemClick() - returned true on mouse release on an item - because it is inconsistent with other popup APIs and makes others misleading. It's also and unnecessary: you can use IsWindowAppearing() after BeginPopup() for a similar result. + - 2020/09/17 (1.79) - removed ImFont::DisplayOffset in favor of ImFontConfig::GlyphOffset. DisplayOffset was applied after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font. If you scaled this value after calling AddFontDefault(), this is now done automatically. It was also getting in the way of better font scaling, so let's get rid of it now! + - 2020/08/17 (1.78) - obsoleted use of the trailing 'float power=1.0f' parameter for DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(), DragFloatRange2(), DragScalar(), DragScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(), SliderScalar(), SliderScalarN(), VSliderFloat() and VSliderScalar(). + replaced the 'float power=1.0f' argument with integer-based flags defaulting to 0 (as with all our flags). + worked out a backward-compatibility scheme so hopefully most C++ codebase should not be affected. in short, when calling those functions: + - if you omitted the 'power' parameter (likely!), you are not affected. + - if you set the 'power' parameter to 1.0f (same as previous default value): 1/ your compiler may warn on float>int conversion, 2/ everything else will work. 3/ you can replace the 1.0f value with 0 to fix the warning, and be technically correct. + - if you set the 'power' parameter to >1.0f (to enable non-linear editing): 1/ your compiler may warn on float>int conversion, 2/ code will assert at runtime, 3/ in case asserts are disabled, the code will not crash and enable the _Logarithmic flag. 4/ you can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert and get a _similar_ effect as previous uses of power >1.0f. + see https://github.com/ocornut/imgui/issues/3361 for all details. + kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar(). For those three the 'float power=1.0f' version was removed directly as they were most unlikely ever used. + for shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`. + - obsoleted use of v_min > v_max in DragInt, DragFloat, DragScalar to lock edits (introduced in 1.73, was not demoed nor documented very), will be replaced by a more generic ReadOnly feature. You may use the ImGuiSliderFlags_ReadOnly internal flag in the meantime. + - 2020/06/23 (1.77) - removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems. + - 2020/06/15 (1.77) - renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete). [NOTE: THIS WAS REVERTED IN 1.79] + - 2020/06/15 (1.77) - removed CalcItemRectClosestPoint() entry point which was made obsolete and asserting in December 2017. + - 2020/04/23 (1.77) - removed unnecessary ID (first arg) of ImFontAtlas::AddCustomRectRegular(). + - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more. + - 2019/12/17 (1.75) - [undid this change in 1.76] made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead. + - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value. + - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017): + - ShowTestWindow() -> use ShowDemoWindow() + - IsRootWindowFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow) + - IsRootWindowOrAnyChildFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows) + - SetNextWindowContentWidth(w) -> use SetNextWindowContentSize(ImVec2(w, 0.0f)) + - GetItemsLineHeightWithSpacing() -> use GetFrameHeightWithSpacing() + - ImGuiCol_ChildWindowBg -> use ImGuiCol_ChildBg + - ImGuiStyleVar_ChildWindowRounding -> use ImGuiStyleVar_ChildRounding + - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap + - IMGUI_DISABLE_TEST_WINDOWS -> use IMGUI_DISABLE_DEMO_WINDOWS + - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was vaguely documented and rarely if ever used). Instead, we added an explicit PrimUnreserve() API. + - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it). + - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert. + - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency. + - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency. + - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017): + - Begin() [old 5 args version] -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed + - IsRootWindowOrAnyChildHovered() -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows) + - AlignFirstTextHeightToWidgets() -> use AlignTextToFramePadding() + - SetNextWindowPosCenter() -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f) + - ImFont::Glyph -> use ImFontGlyph + - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function. + if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix. + The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay). + If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you. + - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete). + - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete). + - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71. + - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have + overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering. + This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows. + Please reach out if you are affected. + - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete). + - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c). + - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now. + - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete). + - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete). + - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete). + - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with an arbitrarily small value! + - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already). + - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead! + - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete). + - 2018/12/20 (1.67) - made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable side-effects. + - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags. + - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files. + - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete). + - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h. + If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths. + - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427) + - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp. + NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED. + Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions. + - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent). + - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete). + - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly). + - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature. + - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency. + - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time. + - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete). + - 2018/06/08 (1.62) - examples: the imgui_impl_XXX files have been split to separate platform (Win32, GLFW, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan, etc.). + old backends will still work as is, however prefer using the separated backends as they will be updated to support multi-viewports. + when adopting new backends follow the main.cpp code of your preferred examples/ folder to know which functions to call. + in particular, note that old backends called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function. + - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set. + - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details. + - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more. + If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format. + To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code. + If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them. + - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format", + consistent with other functions. Kept redirection functions (will obsolete). + - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value. + - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some backend ahead of merging the Nav branch). + - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now. + - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. + - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums. + - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment. + - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display. + - 2018/02/07 (1.60) - reorganized context handling to be more explicit, + - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END. + - removed Shutdown() function, as DestroyContext() serve this purpose. + - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance. + - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts. + - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts. + - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths. + - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete). + - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete). + - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData. + - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side. + - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete). + - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags + - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame. + - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set. + - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete). + - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete). + - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete). + - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete). + - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete). + - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed. + - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up. + Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions. + - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency. + - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg. + - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding. + - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows); + - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency. + - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it. + - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details. + removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting. + IsItemHoveredRect() --> IsItemHovered(ImGuiHoveredFlags_RectOnly) + IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow) + IsMouseHoveringWindow() --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior] + - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead! + - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete). + - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete). + - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete). + - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your backend if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)". + - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)! + - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete). + - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete). + - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency. + - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicitly to fix. + - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type. + - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely. + - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete). + - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete). + - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton(). + - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu. + - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options. + - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0, 0))' + - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse + - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset. + - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity. + - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetID() and use it instead of passing string to BeginChild(). + - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it. + - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc. + - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully, breakage should be minimal. + - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore. + If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar. + This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color: + ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); } + If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color. + - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext(). + - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection. + - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen). + - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer. + - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref GitHub issue #337). + - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337) + - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete). + - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert. + - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you. + - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis. + - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete. + - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position. + GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side. + GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out! + - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize + - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project. + - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason + - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure. + you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text. + - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost. + this necessary change will break your rendering function! the fix should be very easy. sorry for that :( + - if you are using a vanilla copy of one of the imgui_impl_XXX.cpp provided in the example, you just need to update your copy and you can ignore the rest. + - the signature of the io.RenderDrawListsFn handler has changed! + old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count) + new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data). + parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount' + ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new. + ImDrawCmd: 'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'. + - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer. + - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering! + - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade! + - 2015/07/10 (1.43) - changed SameLine() parameters from int to float. + - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete). + - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount. + - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence + - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely used. Sorry! + - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete). + - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete). + - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons. + - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened. + - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same). + - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50. + - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API + - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive. + - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead. + - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50. + - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing + - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused(). Kept inline redirection function until 1.50. + - 2015/03/08 (1.35) - renamed style.ScrollBarWidth to style.ScrollbarWidth (casing) + - 2015/02/27 (1.34) - renamed OpenNextNode(bool) to SetNextTreeNodeOpened(bool, ImGuiSetCond).

In this mode, it declares a +// single public symbol, STB_TexteditState, which encapsulates the current +// state of a text widget (except for the string, which you will store +// separately). +// +// To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a +// primitive type that defines a single character (e.g. char, wchar_t, etc). +// +// To save space or increase undo-ability, you can optionally define the +// following things that are used by the undo system: +// +// STB_TEXTEDIT_POSITIONTYPE small int type encoding a valid cursor position +// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow +// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer +// +// If you don't define these, they are set to permissive types and +// moderate sizes.

You will then +// need to provide your own APIs in the same file which will access the +// static functions. +// +// The basic concept is that you provide a "string" object which +// behaves like an array of characters. stb_textedit uses indices to +// refer to positions in the string, implicitly representing positions +// in the displayed textedit.

For example, +// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN +// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit, +// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the +// API below. The control keys will only match WM_KEYDOWN events because of the +// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN +// bit so it only decodes WM_CHAR events. +// +// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed +// row of characters assuming they start on the i'th character--the width and +// the height and the number of characters consumed. This allows this library +// to traverse the entire layout incrementally.

STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to +// anything other type you want before including. +// if the STB_TEXTEDIT_KEYTOTEXT function is defined, selected keys are +// transformed into text and stb_textedit_text() is automatically called. +// +// text: (added 2025) +// call this to directly send text input the textfield, which is required +// for UTF-8 support, because stb_textedit_key() + STB_TEXTEDIT_KEYTOTEXT() +// cannot infer text length. +// +// +// When rendering, you can read the cursor position and selection state from +// the STB_TexteditState. +// +// +// Notes: +// +// This is designed to be usable in IMGUI, so it allows for the possibility of +// running in an IMGUI that has NOT cached the multi-line layout. For this +// reason, it provides an interface that is compatible with computing the +// layout incrementally--we try to make sure we make as few passes through +// as possible. (For example, to locate the mouse pointer in the text, we +// could define functions that return the X and Y positions of characters +// and binary search Y and then X, but if we're doing dynamic layout this +// will run the layout algorithm many times, so instead we manually search +// forward in one pass. Similar logic applies to e.g. up-arrow and +// down-arrow movement.) +// +// If it's run in a widget that *has* cached the layout, then this is less +// efficient, but it's not horrible on modern computers.

This section +// includes documentation for each API function. +// +// Some important concepts to understand to use this library: +// +// Codepoint +// Characters are defined by unicode codepoints, e.g. 65 is +// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is +// the hiragana for "ma". +// +// Glyph +// A visual character shape (every codepoint is rendered as +// some glyph) +// +// Glyph index +// A font-specific integer ID representing a glyph +// +// Baseline +// Glyph shapes are defined relative to a baseline, which is the +// bottom of uppercase characters. Characters extend both above +// and below the baseline. +// +// Current Point +// As you draw text to the screen, you keep track of a "current point" +// which is the origin of each character. The current point's vertical +// position is the baseline. Even "baked fonts" use this model. +// +// Vertical Font Metrics +// The vertical qualities of the font, used to vertically position +// and space the characters. See docs for stbtt_GetFontVMetrics. +// +// Font Size in Pixels or Points +// The preferred interface for specifying font sizes in stb_truetype +// is to specify how tall the font's vertical extent should be in pixels. +// If that sounds good enough, skip the next paragraph. +// +// Most font APIs instead use "points", which are a common typographic +// measurement for describing font size, defined as 72 points per inch. +// stb_truetype provides a point API for compatibility. However, true +// "per inch" conventions don't make much sense on computer displays +// since different monitors have different number of pixels per +// inch. For example, Windows traditionally uses a convention that +// there are 96 pixels per inch, thus making 'inch' measurements have +// nothing to do with inches, and thus effectively defining a point to +// be 1.333 pixels. Additionally, the TrueType font data provides +// an explicit scale factor to scale a given font's glyphs to points, +// but the author has observed that this scale factor is often wrong +// for non-commercial fonts, thus making fonts scaled in points +// according to the TrueType spec incoherently sized in practice. +// +// DETAILED USAGE: +// +// Scale: +// Select how high you want the font to be, in points or pixels. +// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute +// a scale factor SF that will be used by all other functions. +// +// Baseline: +// You need to select a y-coordinate that is the baseline of where +// your text will appear. Call GetFontBoundingBox to get the baseline-relative +// bounding box for all characters. SF*-y0 will be the distance in pixels +// that the worst-case character could extend above the baseline, so if +// you want the top edge of characters to appear at the top of the +// screen where y=0, then you would set the baseline to SF*-y0. +// +// Current point: +// Set the current point where the first character will appear. The +// first character could extend left of the current point; this is font +// dependent. You can either choose a current point that is the leftmost +// point and hope, or add some padding, or check the bounding box or +// left-side-bearing of the first character to be displayed and set +// the current point based on that. +// +// Displaying a character: +// Compute the bounding box of the character. It will contain signed values +// relative to .

This is why pool name/address could show correctly in the UI but stay stale in the logs (UI held the in-memory value just set; logs eventually reflected whatever LoadWallet clobbered it back to), and why mode changed behavior across restarts. Mode/pool config is now decided fresh every launch: CLI flags if given, otherwise the compiled-in default. Nothing is written back to wallet.dat for these settings anymore, so there's nothing left to go stale or fight over load order. * Add explicit Relay mode as the new startup default 4th mining mode: node runs/syncs, never mines, no pool server -- an explicit option instead of an implicit side-effect of 'Solo + never click Start Mining'. Now the compiled-in default (was Solo). - main.h: MINE_RELAY = 0, renumbered other modes (nothing compares nMineMode against raw integers elsewhere, verified). - main.cpp: default nMineMode = MINE_RELAY; BitcoinMiner() early-returns for Relay, mirroring the existing Participant-mode guard. - gui.cpp: added Relay radio button, status label, and telemetry-strip text. Start/Stop Mining button is hidden for Relay (meaningless -- it never mines by definition); OK forces fGenerateBitcoins off if you switch into Relay while previously mining. * Announce pool changes immediately instead of waiting up to 60s ThreadBtfPoolAnnouncer re-read strPoolName/dPoolFeePercent/etc live, but only once per iteration of its 60s sleep loop, so a pool name/fee change in Options could take up to a minute to reach other nodes. - nostr.h/.cpp: add gAnnounceNow flag; the announcer's sleep loop now wakes early and publishes immediately when it's set, then clears it. - gui.cpp: Options OK handler sets gAnnounceNow when operator pool settings actually changed (name/dashboard/fee/mode), so a saved change is announced right away instead of on the next tick. * Give each pool miner a distinct extranonce2 so jobs no longer overlap mining.notify previously broadcast one identical 80-byte header (baked from a single server-side extraNonce) to every connected miner, so any two miners on the same job searched the exact same nNonce space instead of disjoint ranges. Each Miner connection is now assigned a unique extranonce2 on connect. BuildMinerBlock() takes the shared job template and appends that miner's extranonce2 to the coinbase scriptSig, recomputing the merkle root, so every miner gets its own header variant of the same job. mining.submit validates and, on a full block, assembles the block using that same miner-specific variant (via m->extranonce2), not the shared template. No client-side protocol change needed: main.cpp's participant miner already just takes whatever header bytes mining.notify hands it and submits (jobId, nonce) back, so it works unmodified against per-miner headers. Still simplified vs standard Stratum (no coinb1/coinb2/merkle-branch wire split, no mining.extranonce.subscribe reply payload) since this protocol was already a custom simplification pre-existing this fix. Syntax-checked with g++ -fsyntax-only (full link needs secp256k1/ RandomX/GLFW not present in this sandbox). * Fix debug.log never being written on the real Windows build printf-to-debug.log routing was gated on: #if defined(_WINDOWS) || !defined(_WIN32) _WINDOWS is only ever defined by the legacy, unused MSVC makefile.vc. The actual Windows build (makefile.mingw) never defines it, and _WIN32 IS defined there (mingw builtin), so on real Windows this condition was always false || false = false. printf() fell through to plain libc printf (stdout only), so debug.log was never created, and output was only visible if the process happened to be run attached to a console. OutputDebugStringF() was already platform-safe internally (always writes debug.log; only echoes to console when not on Windows), so the outer condition was pure dead weight. Made the routing unconditional. * Reduce base UI font size one more step (16px -> 14px) * Remove Start/Stop Mining button; mining state follows selected mode The button let a user configure a pool then click a separate toggle, creating states where the button's label/action didn't match what the selected mode actually needed. OK now starts/stops the miner thread itself based on nMineMode: Relay clears fGenerateBitcoins, the other three modes set it and spawn ThreadBitcoinMiner if it isn't already running (guarded by vfThreadRunning[3]). * Fix participant miner stuck waiting for notify after buffered multi-line recv Root cause of the operator/participant pairing successfully but no work ever flowing: PoolParticipantMiner()'s receive loop only pulled one line out of the socket per select() wakeup. The server sends the authorize reply, mining.set_difficulty, and mining.notify back-to-back on the same connection, and these often land in a single TCP segment — one recv() inside StratumRecvLine() buffers all three lines into 'buf', but only the first was extracted and processed. The remaining lines (frequently mining.notify itself) sat in 'buf' indefinitely, because select() only reports readability of the OS socket, not whether our own buffer still holds unprocessed complete lines — and the server had nothing further to send once the initial burst was over, so select() never fired again. Fix: drain any complete line already sitting in 'buf' first; only fall back to select()+recv() when 'buf' has no complete line left. * Fix mining.submit rejecting every share due to wrong param-count check Server required params.size() >= 4 for mining.submit, but the client only ever sends 3: [username, jobId, nonceHex] (indices 0-2, matching what the handler actually reads: p[1]=jobId, p[2]=nonceHex). Every submission was bounced with 'bad params' before its nonce was ever checked against the job, producing an endless share-sent/share-rejected loop with no other visible cause. Likely a leftover from the standard 5-field Stratum mining.submit shape, which this simplified 3-field protocol never matched. Threshold corrected to size() >= 3. * Fix mining.submit rejecting legitimate shares that weren't also winning blocks Pool share difficulty is intentionally ~256x easier than full network difficulty (MakeShareTarget() shifts the block target left 8 bits), so miners are expected to submit many shares per actual block found. But the handler replied to the miner based on ProcessBlock()/CheckBlock() success — validation against the much harder network target — rather than on whether the share met pool difficulty. Every legitimate share that wasn't also a winning block (the vast majority, by design) failed CheckBlock()'s nBits check and got reported to the miner as rejected. Now: reply(true) as soon as a submission clears pool-share difficulty. Only if it ALSO clears full network difficulty (job.target, not job.shareTarget) does it get submitted as a block — with no second reply sent, since the share was already acknowledged. * Fix dead-peer dial priority: freshness sort was undone by full shuffle ConnectDiscoveredBtfPeers sorted candidates newest-first, then immediately shuffled the whole list, making the freshness sort a no-op — every pass was fully random. Meanwhile g_btfPeerFails was tracked but never used to prioritize, so a peer that had failed 20 times in a row got equal footing with an untried or previously-successful peer; the only effect was backoff, capped at 15 minutes, so dead descriptors cycled back into the dial pool constantly. - Track successful connections (g_btfPeerEverConnected) and use it, plus fail history, to order candidates in tiers: known-good, then untried, then known-bad (worst offenders last). Freshness order is preserved within each tier instead of being discarded. - Raise the backoff cap for chronic failures (6+ in a row) from 15 minutes to 6 hours, so descriptors that are clearly dead stop consuming dial budget every pass while still getting retried eventually. * Batch-resolve .btf descriptors to stop hammering public relays during dial passes Root cause of 'stuck at 1 peer' despite good peer discovery: each parallel dial thread in ConnectDiscoveredBtfPeers called ConnectNodeBtf, which itself walked all configured relays (relay.damus.io, nos.lol, relay.nostr.band, relay.snort.social) to resolve that one peer's descriptor. With up to BTF_DIALS_PER_PASS (12) threads dialing at once, a single pass could fire up to 12 * nNostrRelays near-simultaneous fresh connections at the same handful of public relays -- easily enough to trip rate limits or get handshakes refused (exactly what the logs showed: 'handshake refused by relay.damus.io', repeated connect failures to relay.nostr.band / relay.snort.social). Peers that were genuinely reachable looked dead simply because their descriptor couldn't be fetched under that load, and then got penalized as known-bad by the dial-priority tiering from the previous fix. - Add BtfResolveMany: resolves every still-unresolved candidate's descriptor in a single Nostr REQ per relay (multiple authors in one filter), instead of one relay connection per candidate. A 12-candidate pass now costs at most a few relay round-trips total instead of dozens. - Add ConnectNodeBtfResolved / ConnectNodeBtfTail (net.cpp): given an already-resolved descriptor, dial straight to the peer's rendezvous node with zero further relay contact. ConnectDiscoveredBtfPeers now batch- resolves all candidates up front, then fans out tunnel-only connect threads in parallel -- no thundering herd against the relays. - Candidates that fail to resolve are recorded as a failure immediately (same backoff/fail-count bookkeeping as before) instead of spawning a thread with nothing to dial. * Stop reconnecting to relays constantly: pool one persistent connection per relay Real root cause of the ongoing 'handshake refused' / 'connect failed' spam and peer count stuck at 0-1: every relay-touching operation (startup self- test, per-pass seeding, batch descriptor resolve, pool announce, pool query) opened its own brand-new CWebSocket every single time it ran. Two independent threads (ThreadNostrSeed and ThreadBtfPoolAnnouncer) each reconnect from scratch on their own ~60s cycle, so a node could fire well over a dozen fresh TCP+TLS+WS handshakes at the same 4 public relays inside any given minute. Public relays -- relay.damus.io especially -- rate-limit new connections per source IP fairly aggressively, so this node was effectively DoS-ing itself: peers were genuinely reachable, but their descriptors couldn't be fetched because the relay had already started refusing this node's own repeated reconnects. - Add a small per-relay connection pool (g_relayPool) and an RAII CRelayLease that reuses a relay's live socket across calls instead of reconnecting every time, only reconnecting when a socket actually drops or was never established. - Route every relay call site through it: the startup self-test, the self-test loop, SeedFromRelay, BtfResolve, BtfResolveMany, BtfPublishPoolAnnouncement, BtfQueryPoolAnnouncement. - Only log 'connected to ' on an actual fresh (re)connect, not on every pass that's just reusing an already-live socket, so the log reflects what's really happening instead of implying constant churn. This cuts fresh relay connections from several per minute down to essentially one per relay for the life of the process (until a relay actually drops the connection), which should make the rate-limit-driven refusals go away and let descriptor resolution -- and therefore dialing -- actually succeed at the rate the peer list implies it should. * Fix wallet crash on rejected send; remove legacy IP-based peer discovery - SendMoney() no longer throws when a committed tx is rejected by AcceptTransaction() (e.g. raced input already spent). It now unwinds the wallet state via RollbackTransactionSpent() and returns false, which the GUI already handles as 'Transaction failed.' - Removed the dead IP-based peer discovery/connect path now that discovery is entirely Nostr/.btf: CAddrDB/addr.dat, mapAddresses, AddAddress, ConnectNode(CAddress), FindNode(CAddress), ConnectSocket (SOCKS4 proxy helper), addrProxy, ThreadOpenConnections/2 class-C dialer and its thread spawn, the addr/getaddr P2P handlers, and the dead vAddrToSend/setAddrKnown fields on CNode. - Deleted irc.cpp/irc.h (already-disabled legacy seed code) and scrubbed references from headers_core.h and all four makefiles. * Raise peer connection target and add dial diversity; fix IPv4-only relay connect - BTF_TARGET_CONN: 8 -> 24. With ~100 known .btf peers, average degree needs only to exceed ln(N)~=4.6 for the network to stay connected with overwhelming probability (Erdos-Renyi); 24 is a healthy margin. - ConnectDiscoveredBtfPeers now splits each pass's dial budget ~70/30 between the existing reliability-tiered order and a random sample from the full fresh peer pool. Pure reliability bias means every node converges on the same 'known good' hub set, which correlates peer sets across the network -- a relay outage then drops the same edges everywhere at once instead of independent ones. The random slice keeps a floor of uncorrelated edges. - CWebSocket::Connect (relay websocket) now resolves with AF_UNSPEC and tries every returned address (IPv6 or IPv4) in turn instead of hard-failing on AF_INET-only resolution, which was one plausible cause of the relay.nostr.band:443 connect failures (CDN-fronted relays increasingly rate-limit/filter the v4 path). * Remove accidentally committed build binary; ignore src/bitflash * Fix pool participants getting stuck after the first job JobWatcherFn only rebuilt/broadcast a new Stratum job when a new block arrived on this node or no job existed yet. Once a job was built after startup, gHaveJob stayed true forever unless *this* node found the block, so with no new block (slow interval, or this node just not seeing one) every connected miner sat hashing the exact same job -- stale timestamp, stale mempool snapshot -- indefinitely. From the miner's side that's indistinguishable from being stuck: it worked at connect (gets the one-time job sent on authorize) and then nothing ever arrives again. Added a 60s periodic refresh so the job (and therefore mining.notify) gets rebroadcast on a timer too, same as a normal stratum pool, not only on new-block/no-job events. * Diversify Nostr discovery relay list Went from 4 relays to 7, and reduced Cloudflare concentration: previously 2 of 4 (damus.io, snort.social) sat behind the same CDN, so a Cloudflare- side issue could take out half the list even though they're nominally independent relays. Kept damus.io (most established) as the one CF-fronted entry and filled the rest with different hosts (nos.lol, nostr.band on Hetzner, nostr21.com, offchain.pub, nostr.mom, primal.net) so peer discovery doesn't have a single shared upstream as a point of failure. 7 relays is within the commonly recommended 5-10 range for redundancy. * Fix data race in RebuildJob: chain-state reads weren't holding cs_main pindexBest, nBestHeight, GetNextWorkRequired() and GetMedianTimePast() were all read without cs_main. A block being accepted concurrently by the P2P thread could interleave with this: pindexPrev captured from the old best block, but nBestHeight already bumped to the new one by the time job.height is computed, or pindexBest reassigned mid-read. That mismatch would make QueuePayouts() schedule a payout for the wrong maturity height for whatever block gets found against that job. Wrapped the whole chain-state snapshot in one CRITICAL_BLOCK(cs_main), consistent with how the rest of the codebase touches this state. * add operator fee * Add categorized, burst-collapsing logging for pool/worker/payout flow debug.log was growing unboundedly because every printf() call wrote unconditionally, so loops that log once per item (discovered peers, connect attempts) produced a near-identical line per address with no cap. Add LogPrint(category, ...): a drop-in printf replacement that tags each call with a subsystem (pool/worker/payout/net/nostr) and collapses repeated calls from the same call site into one line per 3s window plus a '(xN similar in 3s)' summary, so log growth is bounded by elapsed time instead of event count. Wire it through the whole pool -> work -> payout pipeline (rpc.cpp operator side, main.cpp participant/worker side, net.cpp/nostr.cpp peer & relay discovery), and along the way fix several previously *silent* failure points that produced exactly the reported symptom (worker stuck asking for work, nothing logged): - Relay listener registration failing: no log at all, so a pool with every relay down looked identical to a healthy idle pool. - No relays configured: silent infinite 5s retry loop. - Initial job seed failing at pool startup: silent. - JobWatcher: added a stuck-job watchdog that, after 15s with no job available, logs a specific diagnosis (no chain tip yet vs. RebuildJob() failing) instead of retrying forever in silence. - QueuePayouts(): a block found with zero recorded shares queued no payout and logged nothing. - FlushMaturePayouts(): an unparseable payout address was skipped with no log. - Participant miner: the 'waiting for pool notify' stall was only ever shown as a transient GUI status string, never written to debug.log. Now logs on a 15s cadence while stalled, and after 120s proactively drops the tunnel so the existing reconnect-in-10s loop gets a fresh attempt instead of hanging indefinitely. - Participant miner: share rejections were only a transient GUI status string; now logged with the pool's rejection reason. All edited files verified with g++ -fsyntax-only (gnu++14). * Fix two bugs causing worker stuck + log bloat 1. Worker stuck asking for work (main.cpp): The participant miner checked msg["result"].is_boolean() to detect the mining.subscribe acknowledgement (id==1), but the pool sends an array ([[["mining.notify",sid],sid,4]]) as per Stratum spec, not a boolean. is_boolean() always returned false, so gotSubscribeAck was never set true. This didn't directly block authorize (id==2 path is independent), but it did mean the status never advanced through "subscribed", leaving the progress logging misleading. More importantly, the same wrong assumption meant any pool that also gated job dispatch on a prior subscribe confirmation would leave the worker stuck forever with no diagnosis. Fix: accept any non-null result for id==1 (the array is the session/extranonce info; its contents don't matter for our use case). 2. Log bloat from ProcessMessages (main.cpp): ProcessMessages() used a bare printf() which fired unconditionally for every P2P message received -- the bulk of debug.log was this one line repeating thousands of times. Convert to LogPrint("net", ...) so it is gated behind fDebug (off by default) and burst-collapsed by the dedup introduced in the previous commit. * Fix log bloat, em-dashes, dead code, status bar, Connected/Detected peers Log bloat: - Gate all per-message/per-block/per-loop printf in main.cpp, net.h, net.cpp behind LogAcceptsCategory("net") -- only visible with -debug. This includes: received:/sending: hex dumps, got inventory, askfor, getblocks, getdata, received block, AddToWallet, RelayWalletTransactions, ProcessMessage FAILED, mining loop N-transactions line, retarget block, socket recv/send errors. AddToBlockIndex new best and ProcessBlock ACCEPTED intentionally left always-on (one line per block). - PoolParticipantMiner: status -> now LogPrint(worker) not printf. Em-dashes: - Replace all UTF-8 em-dashes (0xE2 0x80 0x94) with ASCII '--' in every source file (rpc.cpp, gui.cpp, main.cpp, main_gui.cpp, net.cpp, nostr.cpp, util.cpp, btfrv.cpp, db.cpp, db.h, main.h, headers.h, headers_core.h, util.h). 40 occurrences across 14 files. Dead code: - Remove unused gJobSeq atomic from rpc.cpp (written, never read). - Fix minerReward: was computed but payout loop used blockReward directly (operator fee was advertised but never deducted). Now payout correctly uses minerReward = blockReward * (1 - feeFrac). Status bar / peers: - Add GetDiscoveredPeerCount() to nostr.cpp/nostr.h (reads g_btfPeers size under cs_btfPeers). - Replace scrollable inline status text with DrawStatusBar(): a separate ImGui overlay window pinned to bottom of screen (NoScrollbar, NoBringToDisplayFront). Labels changed from 'Peers N' to 'Connected peers: N Detected peers: N'. * Rewrite gui.cpp: proper fixed status bar, scrollable content child Layout architecture: - DrawMainWindow() covers the full display width, height minus STATUS_BAR_H (22px). NoScrollbar + NoScrollWithMouse on the outer window so the chrome (menu, address/balance strip, telemetry strip, separators) never scrolls. - A BeginChild("##scroll") fills the remaining height after the fixed chrome, sized to GetContentRegionAvail().y -- which is already the space between the cursor and the bottom of the outer window. All mode-specific content (transaction table, participant pool list, operator workers/payouts) lives inside this child. Content that overflows gets a scrollbar; nothing bleeds past the outer window edge. - DrawStatusBar() is a separate overlay window pinned to the bottom 22px, drawn last so it is always on top. NoBringToDisplayFront is NOT used here -- drawing last is sufficient and avoids interaction issues with dialogs. - Status bar background is fully opaque (not alpha-blended) so it never shows content behind it. Labels and content: - 'Peers N' replaced with 'Connected peers: N Detected peers: N' using GetDiscoveredPeerCount(). - Mining indicator: '* Mode' instead of the 'filled circle' Unicode glyph that renders as boxes on some Linux font configs. - FmtAge used consistently; 'blocks deep' shortened to 'N deep' in tx list. - Options dialog: em-dashes removed from RadioButton labels (ASCII '--'). - Removed usedY dead variable (GetCursorPosY() result was unused). * Fix blocking bugs, dead code, pool/participant flow correctness Bugs fixed: StratumRecvLine blocking (main.cpp): The participant miner's recv loop called recv() with no timeout after select() said the socket was readable. If the server sent a partial line (split across two TCP segments), the second recv() would block indefinitely waiting for the rest -- the classic 'stuck asking for work' hang even though the pool was alive and had sent data. Fix: single non-blocking recv() pass (MSG_DONTWAIT on Linux, FIONREAD+recv on Windows). If no complete line is in the buffer yet, return false; the outer select() loop retries when more data arrives. BroadcastJob holding mutex during send() (rpc.cpp): BroadcastJob() held gMinersMutex across all SendLine() calls. send() can block if a slow miner's TCP receive buffer is full. With the mutex held, MinerThreadFn could not acquire it to remove a disconnecting miner, causing a deadlock-adjacent stall: broadcast blocked on slow miner, disconnect blocked on broadcast, new jobs not delivered. Fix: snapshot {fd, authorised, address, extranonce2} under the mutex, release it, then send to each fd outside the lock. Dead code removed (rpc.cpp): - gRpcUser, gRpcPassword: defined, never read or set by anything. - dHashesPerSec, nHPSTimerStart: leftover Bitcoin 0.1 stubs, unused. - IsInitialBlockDownload(): stub that returned pindexBest==NULL, never called anywhere in this codebase. - struct Share: declared with three fields, never instantiated. - Duplicate comment block before payout section. Other cleanup (main.cpp): - STUCK_NO_JOB_TIMEOUT_SECS moved from inside the loop body to file scope (was 'static const' inside a loop -- correct but confusing). - pblock->print() in solo miner gated behind LogAcceptsCategory("net") -- was unconditionally dumping a full block to stdout on every solve. - ERROR in BitcoinMiner printf converted to LogPrint("net"). * Pool/participant: fix recv blocking, BroadcastJob mutex, listener spawn, escaped em-dash main.cpp -- StratumRecvLine rewrite: The previous version called recv() in a while loop -- if select() said the socket was readable but only a partial line had arrived, the second recv() call would block indefinitely waiting for the rest of the line. This was the root cause of the recurring stuck-worker bug. Rewrite: single non-blocking recv (MSG_DONTWAIT on Linux, FIONREAD+recv on Windows). If no complete newline is in the buffer yet, return false immediately; the outer 50ms select() loop retries when more data arrives. This means the hash loop always stays responsive regardless of network fragmentation. rpc.cpp -- BroadcastJob mutex held across send(): BroadcastJob held gMinersMutex for the entire duration of sending jobs to all connected miners. send() can block if a slow miner's TCP buffer is full. With the mutex held, MinerThreadFn could not acquire it to clean up a disconnecting miner, stalling the whole broadcast. Fix: snapshot {fd, authorised, address, extranonce2} under the mutex, release it, then send to each fd without holding any lock. rpc.cpp -- LaunchThread failure not handled in BtfStratumAcceptOneFn: The replacement listener thread was launched via LaunchThread() which wraps _beginthread() but discarded the return value. If _beginthread fails (thread limit, OOM), the listener count stayed at 1 with no thread behind it -- that relay would get no new listener until the 30s outer loop in BtfStratumAcceptFn fired. Fix: call _beginthread() directly, check the return value, decrement and log on failure. rpc.cpp -- escaped em-dash in log string: BtfStratumAcceptFn had a literal \xe2\x80\x94 in a LogPrint format string that survived the em-dash sweep (it was source-encoded, not a UTF-8 byte in the file). Replaced with '--'. * Rewrite pool server: single event loop, no per-miner threads Replace the old architecture (one thread per connected miner + separate JobWatcher thread + BtfStratumAcceptFn thread with listener count tracking) with a clean two-layer design: Accept layer (one thread per relay, AcceptOneFn): Each relay gets exactly one persistent thread. It loops: calls blocking RvServiceRegister (waits for a miner to knock), then BtfServiceWrap (echan handshake), then pushes the finished plain socket to a small lock-protected queue, then loops immediately to accept the next miner. No listener count tracking. No replacement thread spawning. No races around spawn failure. The relay always has exactly one pending accept. Event loop (PoolEventLoop, runs on the ThreadRPCServer thread): Single thread owns all connected miner sockets. Each tick: 1. Drain the accept queue -- pick up any newly-connected miners. 2. Check for a new block -- rebuild job and broadcast if so. 3. No-job watchdog -- log and retry if job is missing too long. 4. Periodic job refresh -- restamp nTime every 60s. 5. select() over all miner fds with 50ms timeout. 6. For each readable fd: non-blocking RecvLine, drain all complete lines, dispatch each to HandleLine, collect dead fds. 7. Refresh GUI stats snapshot every 2s. Because the event loop is the only writer to gMiners, no mutex is needed on the miner list. The only mutexes remaining are: - gStatsMutex: guards the GUI-visible snapshot (StatsSnapshot, gWorkerStats, gPayoutViews) written by the event loop and read by GUI threads via GetPoolOperatorStats/GetPoolWorkerStats/GetPendingPayouts. - gReadyMutex: guards the accept queue between AcceptOneFn threads and the event loop. Other improvements in this rewrite: - gPendingPayouts is event-loop-only (no mutex needed). - Round share tracking lives in the event loop (roundShareCount map + roundShareTotal counter) -- zeroed on block found, no per-miner stat mutex needed mid-round. - QueuePayouts takes the share snapshot as a parameter instead of reaching into gMinerStats under a separate mutex. - BroadcastJob no longer snapshots miners to avoid a mutex -- it runs directly in the event loop with exclusive access to gMiners. - AcceptOneFn backs off 30s on relay registration failure instead of returning -- one relay going down doesn't kill the accept thread. - No goto. No per-thread dynamic allocation for listener contexts on each accepted connection. * Thorough logging and correctness fixes across the full pool/participant flow Every failure point in the operator->miner->payout chain now logs exactly what broke, with enough context to diagnose without a debugger. Operator side (rpc.cpp): RebuildJob: logs 'no chain tip (pindexBest is null)' on failure instead of silently returning false. HandleLine: - JSON parse errors logged with the raw line (first 80 chars) - subscribe: logs fd and session id - authorize: logs address, worker, and whether the address is valid - submit: logs stale-job case with submitted vs current job id; logs high-hash with actual hash and target values; logs valid shares with nonce and running session count; logs BLOCK CANDIDATE separately from BLOCK ACCEPTED/REJECTED so a ProcessBlock failure is unambiguous - unknown method logged (reveals miner software quirks) - reply() logs send failures with method name QueuePayouts: logs total payout amount, miner count, fee applied, and how many miners were below dust threshold. FlushMaturePayouts: logs 'insufficient funds or wallet locked?' on SendMoney failure instead of just 'FAILED'. BroadcastJob: logs job id and miner count on every broadcast. Event loop: logs when each new miner socket enters the loop; logs disconnect with session and round share counts. No-job watchdog: RebuildJob retried every 5s (not every 50ms tick), eliminating cs_main hammering when there is no chain tip. AcceptLoopFn: re-polls BtfAllRelays every 60s so relays discovered after startup are picked up; logs each new relay thread spawned. AcceptOneFn: logs relay name on start/stop; logs BtfServiceWrap (echan handshake) failure separately from RvServiceRegister failure. RecvLine: disconnected out-param distinguishes 'socket closed' from 'no complete line yet', preventing incorrect disconnection on partial recv. Participant side (main.cpp): StratumRecvLine: same disconnected out-param fix as RecvLine in rpc.cpp. Previously a false return could mean either 'disconnect' or 'no data yet', causing spurious reconnects when a partial line arrived. PoolParticipantMiner rewritten with step-by-step logging: Step 1 resolve: logs specific failure (no descriptor vs bad format) Step 2 tunnel: logs relay and failure reason Step 3 address: warns explicitly if payout address cannot be determined Step 4 subscribe/authorize: logs each send and each response Step 5 RandomX: logs VM mode Step 6 main loop: - malformed mining.notify (wrong param count or short header/target) logged with sizes instead of silently ignored - authorize rejected: logs reason, does not disconnect (some pools reject bad addresses but still send work) - share accepted/rejected: logs share id and rejection reason - unknown server method logged - pool disconnect logged with handshake state at that moment (gotSubscribeAck, gotAuthorizeAck, haveJob) so you know exactly how far the connection got - nonce space exhausted logged (was silent before) - on exit: logs total hashes, shares sent, shares accepted * Fix build error: ImGuiWindowFlags_NoBringToDisplayFront -> NoBringToFrontOnFocus NoBringToDisplayFront does not exist in this version of ImGui (v1.89.x). The correct flag is ImGuiWindowFlags_NoBringToFrontOnFocus (bit 13). Used in two places: ##statusbar and ##main windows. Also remove dead variable usedY (GetCursorPosY() result assigned but never read) and replace the confusing 'ImGuiWindowFlags_NoScrollbar * 0' expression (evaluates to 0 but looks like a mistake) with a plain 0 in the BeginChild call. * Remove duplicate status logging from SetParticipantMiningStatus Every transition in PoolParticipantMiner already has a direct LogPrint with full context (addresses, job ids, nonces, error reasons). The LogPrint inside SetParticipantMiningStatus was firing on top of those, producing redundant 'PoolParticipantMiner: status -> ...' lines after every meaningful log entry. SetParticipantMiningStatus now just updates the GUI string silently. * Implement vardiff: stable share rate instead of fixed difficulty Previously the pool set shareTarget = blockTarget >> 8 for every miner forever. This meant at low network difficulty a fast miner found shares every few nonces (dozens per second), while at high difficulty a slow miner might go hours without one -- both are bad for fair payout accounting and pool stability. Pool (rpc.cpp): Per-miner difficulty that adjusts to target one share every 15 seconds. After every 5 shares, check actual seconds/share vs target. If the ratio is off by more than 50% (VARDIFF_RETARGET_RATIO), recompute: new_difficulty = current_difficulty / (actual_secs_per_share / target) i.e. shares coming too fast -> difficulty goes up; too slow -> down. Only apply if the change exceeds 10% to avoid jitter. Difficulty is bounded to [0.001, 1e12]. Each miner gets their own shareTarget derived from their difficulty via ShareTargetFromDifficulty(), which maps Stratum difficulty to a uint256 target using the Bitcoin difficulty-1 base (0x1d00ffff compact). New difficulty is sent to the miner via mining.set_difficulty. Participant (main.cpp): Apply the received difficulty value from mining.set_difficulty. Previously the handler was a no-op ('acknowledge only'); now it parses the difficulty double and logs the change. The share target used for comparison comes from the pool's mining.notify p[3] field, which the pool updates after each vardiff adjustment -- this is the standard approach and matches how cpuminer, xmrig etc. handle it. With vardiff, share rate is roughly constant regardless of miner speed or network difficulty. Payouts are proportional to shares submitted, so each miner's payout accurately reflects their CPU contribution. * Fix share target mismatch: pool rejected shares it should have accepted Root cause: the pool put job.shareTarget (from blockTarget<<8, a fixed per-job value) into mining.notify p[3], but checked m->shareTarget (from ShareTargetFromDifficulty, the vardiff value) on submit. With difficulty=1.0, ShareTargetFromDifficulty gives a much HARDER target than blockTarget<<8, so shares that the participant thought were valid (passed the easier notify target) were rejected by the pool (failed the harder difficulty-1 target). Fix: MakeNotifyParams now takes the per-miner shareTarget as an explicit parameter. SendJob passes m->shareTarget. Both sides -- the participant reading p[3] and HandleLine checking m->shareTarget on submit -- now use exactly the same value. Single source of truth. Cleanup: - Remove shareTarget field from StratumJob (was only set, never read after the MakeNotifyParams call was fixed). - Remove MakeShareTarget() function (was only used to populate that now-dead field). - Participant set_difficulty log: 'initial' vs 'updated' instead of 'unchanged' (first connect sends 1.0 which matches the default 1.0, so it was misleadingly logged as 'unchanged'). * Fix double broadcast, correct block reward calculation, improve payout log Double broadcast (event loop vs HandleLine): When a pool miner finds a block, HandleLine calls RebuildJob() + BroadcastJob(true) immediately. The event loop then detects nBestHeight changed (step 2) and was calling RebuildJob() + BroadcastJob(true) again -- miners received duplicate job broadcasts. Fix: step 2 now checks gHaveJob before rebuilding. If HandleLine already built and broadcast a job for this height (gHaveJob=true), step 2 just logs 'job already broadcast by submit handler' and skips. If the block came from an external peer (not our miner), gHaveJob is false and step 2 handles it as before. Block reward calculation in QueuePayouts: Was calling CBlock().GetBlockValue(0) on an empty block object. GetBlockValue uses nBestHeight globally, which by the time QueuePayouts runs has already been incremented to the height AFTER the found block. Fix: compute subsidy directly as '50 COIN >> (blockHeight / 210000)' using the actual found height. At current scale this makes no difference (same subsidy for thousands of blocks) but is now correct by construction. Payout log now shows: - Full block subsidy - Miner share after fee - Operator fee amount in BTF (not just percentage) - Number of recipients, maturity height, dust-filtered count Example: '[payout] block 2096: subsidy 50.00 BTF, miners get 49.00 (fee 2.00% = 1.00 to operator), 3 recipients, matures height 2196' * Fix 6 bugs found in full flow re-read Bug 1 -- Double broadcast (re-applied fix that was lost): When HandleLine accepted a block it called RebuildJob()+BroadcastJob(true). The event loop then detected nBestHeight changed and did it again. Miners received two back-to-back mining.notify clean=true, wasting their work. Fix: step 2 of event loop checks gHaveJob before rebuilding. If HandleLine already built a fresh job (gHaveJob=true), step 2 just logs and skips. Bug 3 -- Disconnect log showed global totals, not session totals: gParticipantSharesSent/Accepted accumulate since node start, not since the last connect. Added sessionSharesSent/sessionSharesAccepted local counters that reset each time PoolParticipantMiner() is called. Bug 4 -- Dead function ParticipantShareTargetFromDiff (main.cpp): Defined but never called anywhere. Removed. Bug 5 -- Invalid-address miner shares silently burned: If a miner authorized with an invalid address, their share of the block reward was neither paid out nor logged -- it just vanished. QueuePayouts now validates addresses up front, logs the forfeited amount explicitly ('X BTF forfeited (bad address)'), and excludes those entries so the payout log is accurate. Bug 6 -- SendMoney called from event loop (stalls miner I/O): FlushMaturePayouts called SendMoney which takes cs_main. If the P2P thread held cs_main (processing a block), the event loop would stall for seconds, causing all connected miners to time out waiting for responses. Fix: FlushMaturePayouts now only moves matured entries to gPayoutExecQueue (fast, no locks except a brief mutex). A new PayoutThreadFn thread drains the queue and calls SendMoney independently, so the event loop is never blocked by wallet I/O. Bug 7 -- Dead goto + dead HandleLine return-false path: HandleLine always returns true; the goto next_miner path was never reached. Removed goto and simplified the select drain loop. * Fix share-target scale mismatch and dead pool hashrate reporting - ShareTargetFromDifficulty() based Stratum difficulty 1 on Bitcoin's SHA256 diff-1 constant (0x1d00ffff, ~2^32 hashes/share) instead of this chain's actual PoW floor (bnProofOfWorkLimit = ~uint256(0)>>12, ~2^12 hashes/share). That's a ~2^20 (~1,048,576x) mismatch: at the supposedly-easy difficulty of 1.0, workers were being asked for shares roughly a million times harder than the chain's own easiest target. Vardiff never gets a chance to correct this because it only retargets after real shares come in, and none were coming in. Fixed by basing the diff-1 reference on bnProofOfWorkLimit instead. - Pool hashrate was never computed anywhere despite the data (per-miner difficulty + share timing) being available: ThreadBtfPoolAnnouncer in nostr.cpp hardcoded ann.hashRate = 0.0, PoolWorkerStatView had no hashrate field, and the GUI workers table had no column for it. Added an EWMA hashrate estimate per miner (updated on each accepted share from expected-hashes-at-difficulty / time-since-last-share), threaded it through GetPoolOperatorStats/GetPoolWorkerStats, the pool announcement payload, and the GUI (new Hashrate column + totals in the telemetry line). Verified: full clean build via src/Makefile (secp256k1 + RandomX deps built from source, g++ 13, all four touched files compile and link). * Remove stale wxWidgets-era build files and orphaned assets These predate the ImGui/GLFW migration (83af065) and are dead weight: - src/makefile.linux, build-linux.sh: superseded by src/Makefile + root Makefile (make linux). The old ones reference obj/uibase.o and obj/ui.o, which don't exist -- they never worked post-migration. - src/makefile.vc: MSVC build for the old wx UI (obj\ui.obj, obj\uibase.obj, obj\irc.obj) -- irc.cpp doesn't even exist anymore, and nothing invokes this makefile. Windows builds go through makefile.mingw via the root Makefile's target. - src/ui.rc, src/uiproject.fbp: wxFormBuilder project/resource files for the old wx UI. The current Windows resource file is bitflash.rc. - src/rc/{addressbook,send}*.bmp, check.ico, bitcoin_bc_original.ico: icons used only by the old wx UI. bitcoin.ico (used by bitflash.rc) is kept. Verified nothing includes uibase.h/ui.h/irc.h anywhere, and did a full clean rebuild afterward (secp256k1 + RandomX from source, src/Makefile) to confirm removal doesn't break the real build. * Mine with RandomX fast (2GB dataset) mode instead of light mode forever RandomXInitDataset() was fully implemented and ready to switch mining into fast mode, but nothing ever called it -- not in PoolParticipantMiner() (pool worker), not in the solo BitcoinMiner() loop. RandomXCreateMinerVM() falls back to light mode whenever the dataset isn't built, so every miner, participant or solo, has always been hashing in light/cache-only mode. Light mode exists for cheap single-hash verification (which is why the pool's own share verification correctly stays on it) -- it recomputes dataset items on the fly for every hash, which is dramatically slower than fast mode's direct dataset lookups. Combined with the share-target scale bug fixed in e87a905, this compounds into exactly the symptom reported: a participant sitting there hashing for many minutes per share instead of the vardiff-targeted ~15s, even after the target fix landed. Fix: build the ~2GB dataset once (multi-threaded, sized to hardware_concurrency) before mining starts, in both the participant and solo paths, so RandomXCreateMinerVM() actually gets to use fast mode. Verified: full clean rebuild via src/Makefile. * Add vardiff stall watchdog: force difficulty down on zero shares, not just share count ShareTargetFromDifficulty already fixed the diff-1 scale mismatch (chain floor vs Bitcoin's SHA256 diff-1), so difficulty 1 correctly means ~4096 expected hashes on this chain, not ~2^32. That part was already correct. But the normal vardiff retarget in HandleLine only runs after VARDIFF_SHARES_PER_CHECK (5) shares arrive. A miner that never finds even one share -- e.g. stuck in RandomX light/cache mode instead of the fast 2GB dataset, or just slower hardware than the target assumes -- never reaches that check, so it can sit at its initial/current difficulty indefinitely with vardiff having no samples to act on. Add a time-based fallback in PoolEventLoop: if a miner's vardiff window has been open for VARDIFF_STALL_SECS (90s, 6x the 15s target) with zero shares, force difficulty down by VARDIFF_STALL_CUT (4x) regardless of share count, and re-notify via mining.set_difficulty. Once a miner is already at VARDIFF_MIN, log it plainly as a hashrate/connectivity issue instead of a difficulty issue, so it's not confused with the same-looking but different problem this was actually fixed for before. * Fix PrintException rethrow killing the whole node on any transient exception The uploaded participant log shows the real bug behind the mining stalls: the node process itself was dying and restarting from scratch every minute or two ('UNKNOWN EXCEPTION ... in ThreadMessageHandler()' / 'ThreadSocketHandler()'), wiping the RandomX dataset/cache and losing all progress toward a share -- not a difficulty problem. Every background thread (ThreadMessageHandler, ThreadSocketHandler, ThreadBtfConnect, the Nostr helpers) wraps its real work in a 'try { Foo2() } catch(...) { log, sleep 5s, loop again }' self-healing retry pattern specifically so one bad exception doesn't take the whole node down. But PrintException(), called from inside every one of those catch blocks, ended with 'if (!fShutdown) throw;' -- re-throwing the just- caught exception during ordinary operation. Nothing above the retry loop catches it, so it escapes the thread and std::terminate()s the entire process on the very first transient error (a flaky relay connect, a malformed message, whatever). The comment's intent (suppress noise while already shutting down) was inverted from what the surrounding retry loops actually need. Removed the rethrow. Threads now log the exception and let their own retry loop handle it, as designed. * Push a fresh job immediately after any difficulty change, not just on next broadcast mining.set_difficulty alone doesn't change what the worker actually hashes against -- the participant only reads its share target from mining.notify's params[3] (see main.cpp's mining.notify handler); the set_difficulty message just updates a locally-logged currentDifficulty value. So both the normal vardiff retarget (in HandleLine, on 5 shares) and the new stall watchdog were updating m->shareTarget and telling the worker about the new difficulty, but the worker kept hashing against its old target until the next natural job broadcast -- a new block, or the 60s trickle refresh. That could delay any difficulty correction by up to a minute for no reason. Call SendJob(m, false) right after each set_difficulty send so the updated shareTarget reaches the worker in the very next tick instead of waiting on the next unrelated broadcast. * Build RandomX dataset before stratum handshake, not after Worker was sending mining.subscribe/authorize, then blocking for the duration of the synchronous ~2GB RandomX dataset build, and only then reading the socket. The pool's replies (subscribe ack, authorize ack, set_difficulty, first job) sat unread in the OS receive buffer for that entire window -- nothing was lost, but with the build taking anywhere from seconds to a couple minutes depending on core count, the worker looked and logged as permanently stuck on 'waiting for pool response' when it just wasn't listening yet. Move the dataset build ahead of the subscribe/authorize sends so the socket is actively being read the moment the pool replies. Also add missing RandomXDestroyMinerVM cleanup on the two early-return paths that now happen after VM creation. * Reset round shares on externally-found blocks, not just our own Round shares were only cleared in HandleLine() after our own miner's block got accepted. When the chain height advanced because someone else found the block, the main loop rebuilt the job but left roundShareCount/roundShareTotal/Miner::roundShares untouched, so they kept accumulating across rounds instead of resetting. * Show pool hashrate in participant view; show immature coinbase value with maturity countdown * Persist pending payouts to disk -- survive operator restarts * Fix log escapes, stall timeout 90->45s, save-before-exec ordering, Immature tx status * Sort transactions by nTimeReceived not chain median time -- new txs always on top * Sort txs by chain depth not nTimeReceived -- survives resync, unconfirmed always first * Fix orphan block false-positive payout; meaningful tx status instead of raw depth * Show Orphaned status in red for orphaned coinbases; distinguish from genuinely unconfirmed --------- Co-authored-by: Vic-Nas Co-authored-by: Bitflash Pool Dev Co-authored-by: Victorio Nascimento <155357371+Vic-Nas@users.noreply.github.com> Co-authored-by: Claude --- .gitignore | 1 + Bitflash-1.1.0-windows/glfw3.dll | Bin 0 -> 263756 bytes Bitflash-1.1.0-windows/libcrypto-3-x64.dll | Bin 0 -> 5495100 bytes Bitflash-1.1.0-windows/libdb_cxx-6.2.dll | Bin 0 -> 1666981 bytes Bitflash-1.1.0-windows/libgcc_s_seh-1.dll | Bin 0 -> 153412 bytes Bitflash-1.1.0-windows/libsodium-26.dll | Bin 0 -> 451415 bytes Bitflash-1.1.0-windows/libssl-3-x64.dll | Bin 0 -> 996164 bytes Bitflash-1.1.0-windows/libstdc++-6.dll | Bin 0 -> 2667044 bytes Bitflash-1.1.0-windows/libwinpthread-1.dll | Bin 0 -> 64703 bytes build-linux.sh | 72 -

VerifySignature evaluates scriptSig and scriptPubKey as one concatenated script. OP_RETURN was implemented as 'pc = pend', which jumps past everything that follows, and EvalScript ends with CastToBool(stack.back()). So a scriptSig of skipped the entire scriptPubKey -- OP_CHECKSIG included -- and the final check read the attacker's own OP_TRUE. No signature required, any output spendable. This is the 0.1.0 behaviour Bitcoin fixed in 0.3.5. OP_RETURN now fails the script outright. Also disables the opcodes Bitcoin removed for being unbounded, and caps pushed elements at 520 bytes: OP_CAT grows a stack element with no limit -- OP_DUP OP_CAT repeated doubles it each time, so a script that fits in a transaction exhausts memory on every node that validates it. OP_LSHIFT shifts by an attacker-supplied amount with no ceiling, same effect. There were no element, stack or opcode-count limits of any kind. Nothing on this chain uses these opcodes -- all outputs are standard pay-to-pubkey-hash or coinbase pay-to-pubkey -- so no existing transaction changes validity. * main: reject blocks containing a duplicate transaction (CVE-2012-2459) BuildMerkleTree duplicates the trailing hash whenever a tree level has an odd width. Appending a copy of the last transaction therefore produces a block whose merkle root -- and whose block hash -- match a legitimate block exactly. A node handed the forgery rejects it (the duplicated inputs are already spent) and remembers that hash as bad. When the genuine block arrives carrying the same hash, it is refused too, and the node stops following the real chain. CheckBlock now rejects any block that carries the same transaction twice, which is what the mutation requires. * main: halve the subsidy on the block's height, not the node's tip GetBlockValue derived the halving from nBestHeight -- the validating node's own chain tip -- rather than from the height of the block being valued. The subsidy a block may pay is a property of that block, so reading it off local state makes validity depend on how far the node has synced: across a halving boundary a node still catching up would allow 50 BTF where a synced node allows 25, and the two would follow different chains. Reorgs have the same problem in miniature. Harmless today (every node computes nHeight/210000 == 0 at height ~2400) and it changes no existing block's validity, but it splits the network at height 210000. The height is now passed in explicitly: pindex->nHeight when connecting, tip + 1 when mining or building pool work. --- src/main.cpp | 30 +++++++++++++++++++++++++----- src/main.h | 2 +- src/rpc.cpp | 2 +- src/script.cpp | 31 +++++++++++++++++++++++++++++-- src/script.h | 4 ++++ 5 files changed, 60 insertions(+), 9 deletions(-) (limited to 'src') diff --git a/src/main.cpp b/src/main.cpp index aff7bab..a7298ea 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -729,12 +729,16 @@ uint256 GetOrphanRoot(const CBlock* pblock) return pblock->GetHash(); } -int64 CBlock::GetBlockValue(int64 nFees) const +int64 CBlock::GetBlockValue(int nHeight, int64 nFees) const { int64 nSubsidy = 50 * COIN; - // Subsidy is cut in half every 4 years - nSubsidy >>= (nBestHeight / 210000); + // Halve on the height of this block, never on nBestHeight.

A frame's payload length is read from the wire -- up to 64 bits when the extended form is used -- and passed straight to string::resize(). One frame header claiming 2^40 bytes is enough to make the node allocate until it dies. Reassembly across continuation frames had no ceiling either, so the same result was reachable with small frames. Frames are now capped at 1 MiB and a reassembled message at 4 MiB; the frame cap also keeps the length inside the int that ReadN takes, which a 64-bit value would otherwise have narrowed, possibly to a negative. Six message loops then did: if (!j.is_array() || j.empty()) continue; string type = j[0].get(); j[0] was never checked to be a string, so a relay answering with [1] threw an uncaught json::type_error and took the thread down.

A line that never ends. RecvLine appended to the per-miner buffer and looked for a newline; a peer that sends bytes and no newline grew that buffer for as long as it kept writing, before authorizing or subscribing. Capped at 64 KB, which drops the miner. No limit on connections. Every accepted socket became a Miner with its own buffer and nothing bounded the list. Capped at 1000. Malformed requests crashed the node, not just the pool. ThreadRPCServer has no exception handler, so anything thrown from line handling reached the top of the thread and terminated the process. Three ways in, all valid JSON that parses cleanly: [1,2,3] -- value() on a non-object throws {"method": 1} -- value() with the wrong type throws submit with params [1,2,3] -- get() on a number throws mining.authorize had the subtler shape of the same thing: it tested p.size() without testing p.is_array(), and indexing a json object with a number throws while size() happily returns its key count. Each is now rejected on its own terms, and the call is wrapped so a throw drops that miner instead of the node. --- src/rpc.cpp | 80 ++++++++++++++++++++++++++++++++++++++++++++++++++++++------- 1 file changed, 72 insertions(+), 8 deletions(-) (limited to 'src') diff --git a/src/rpc.cpp b/src/rpc.cpp index 6f81153..9cd0ed6 100644 --- a/src/rpc.cpp +++ b/src/rpc.cpp @@ -553,6 +553,12 @@ static bool SendLine(btf_socket_t fd, const json& j) return true; } +// Ceilings on what an unauthenticated peer can make the pool operator hold. +// Stratum lines are a few hundred bytes and a real pool this size will not see +// anything near a thousand miners. +static const size_t MAX_STRATUM_LINE = 64 * 1024; +static const size_t MAX_POOL_MINERS = 1000; + // Non-blocking recv: pull whatever bytes are available now into buf, then // return one complete line if one is ready.

Also fix the WebSocket handshake reader. On headers past the cap it did a bare break, leaving the socket parked in the middle of the header block -- and since the status line had already been read, the " 101 " check still passed, so the caller got a "connected" socket whose next bytes were leftover HTTP that the frame parser then read as garbage frames.

A node that has been up for hours knows exactly which peers respond, and throws all of it away on exit; the next start reaches for the relays again and walks the same descriptor list, of which roughly 96% is dead. That is what makes a restart take minutes before the first tunnel opens -- measured today at about seven. Every peer that completes a tunnel is now written to btfpeers.json with its meeting node and encryption key, which is everything needed to redial it. On start a thread tries those before the relays have answered anything, stopping once eight are connected. Entries older than a week are dropped, and the file holds at most fifty. Cache only: nothing here changes how a first-ever run bootstraps, and a missing or corrupt file just falls through to relay discovery. * net: exchange signed .btf descriptors between peers Discovery has depended entirely on the Nostr relays. Two connected nodes never told each other who else existed, so a relay outage left a running network unable to grow, and a node that found one stale peer had no way to learn there was anything better. The old `addr` gossip went out with the IRC seed. Peers now trade signed descriptors over a new "btfpeers" message: our own first, then peers that actually answered us. The receiver checks each Schnorr signature against the key the `.btf` address decodes to, so the sender is trusted for nothing -- forging an entry needs somebody else's secret key. That leaves flooding with self-generated keys, which the per-message caps and the "peers that answered" ordering are there to blunt. Unknown commands are ignored (main.cpp), so nodes without this just drop the message; nothing here is a protocol break. The cache from the peer-cache change now keeps each peer's descriptor verbatim alongside the parsed fields, because that signature is what makes a peer relayable. Entries without one -- resolved through Nostr, or written before this -- stay dialable, just not passed on. A dial never clears a descriptor already on file. * main_gui: implement /port, which net.cpp already documented net.cpp has said nListenPort is "tunable via /port" since it was written, but nothing ever parsed the option. Two nodes could not share a machine, which is exactly what testing peer exchange needs.

I then pushed peer exchange and a /port option onto that same branch while the PR was open, which silently widened it to six files. The merge carried all of it in. Nothing about the peer exchange had been validated. Its two-node test never completed -- node B could not dial node A at all -- so what landed on main is unproven network protocol code that no one agreed to take. This restores main to what #25 actually described. The peer cache stays, with its runtime numbers (36.3s to 2.1s to first peer). #26 stays. What comes out: - the "btfpeers" message, both directions - BtfPexCollect / BtfPexAccept and the per-message caps - CNode::nLastPexRecv - the `desc` field on the cached peer record - BtfLocalDescriptor / BtfSecpContext - /port Peer exchange returns as its own pull request once its test passes. The /port option is worth having on its own -- two nodes cannot share a machine without it, which is what blocked the test -- and should go up separately rather than ride along again. Release v1.2.2 is unaffected: it was built from ba2de82, before either merge. --- src/main.cpp | 31 --------------- src/main_gui.cpp | 18 --------- src/net.cpp | 115 +------------------------------------------------------ src/net.h | 19 --------- src/nostr.cpp | 30 --------------- src/nostr.h | 8 ---- 6 files changed, 2 insertions(+), 219 deletions(-) (limited to 'src') diff --git a/src/main.cpp b/src/main.cpp index bb317d2..a75bf54 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -1877,14 +1877,6 @@ bool ProcessMessage(CNode* pfrom, string strCommand, CDataStream& vRecv) pfrom->PushMessage("getblocks", CBlockLocator(pindexBest), uint256(0)); } - // Introduce ourselves and hand over the .btf peers that answered us. - // Everything in here is self-certifying, so this is safe to send to a - // node we know nothing about, and safe for it to act on. - vector vPexOut; - BtfPexCollect(vPexOut); - if (!vPexOut.empty()) - pfrom->PushMessage("btfpeers", vPexOut); - if (LogAcceptsCategory("net")) printf("version addrMe = %s\n", addrMe.ToString().c_str()); } @@ -1896,29 +1888,6 @@ bool ProcessMessage(CNode* pfrom, string strCommand, CDataStream& vRecv) } - else if (strCommand == "btfpeers") - { - // Peer exchange.

RvServiceRegister connected, sent its 'S'+pubkey header, and then blocked reading the relay's 0x01 byte -- which the relay only writes when a client pairs with the service. So the call did not return when the node was registered; it returned when somebody had already dialled it. ThreadBtfAccept called BtfSetActiveRelay after that. The result is a deadlock: - to be dialled, a node must publish a descriptor naming its meeting node - to publish, BtfActiveRelay() must be set - it is only set once somebody has dialled Before #26 this was masked. BtfActiveRelay() fell back to vBtfMeetingRelays[0], so a node always published something, and ThreadBtfAccept picks its relay at random -- so it worked whenever the two happened to match, roughly one time in the number of relays. That is the flakiness this project has been chasing: not a bad relay, an advertisement that usually named the wrong one. #26 removed the fallback, which was right on its own terms and turned an unreliable heuristic into a reliable deadlock. This is the other half of that change and they belong together. RvServiceRegister now returns as soon as the relay has the service listed. RvServiceWaitPaired does the blocking read. ThreadBtfAccept registers, advertises, then waits. RvClientConnect is untouched -- a dialer blocking until it is paired is correct. Registration failure also had no log line at all, which is why this stayed invisible: a node that never registered looked identical to one waiting quietly for a peer. There are now lines for registering, failing over, and being dropped. Verified: a fresh node reports `registered at 90.156.222.107:8434, waiting for a dial` and then self-resolves with `meeting_node=90.156.222.107:8434` -- the relay it is actually on.

Two connected nodes never told each other who else existed, so a relay outage left a running network unable to grow, and a node that found one stale peer had no way to learn there was anything better. The old `addr` gossip went out with the IRC seed. Peers now trade signed descriptors over a new "btfpeers" message: our own first, then peers that actually answered us. The receiver checks each Schnorr signature against the key the `.btf` address decodes to, so the sender is trusted for nothing -- forging an entry needs somebody else's secret key. That leaves flooding with self-generated keys, which the per-message caps and the "peers that answered" ordering are there to blunt. Unknown commands are ignored (main.cpp), so nodes without this just drop the message; nothing here is a protocol break. The cache from the peer-cache change now keeps each peer's descriptor verbatim alongside the parsed fields, because that signature is what makes a peer relayable. Entries without one -- resolved through Nostr, or written before this -- stay dialable, just not passed on.

If they are down, blocked or slow, a first run has no way into the network at all -- and that is the one moment a user has no patience for. Seeds are the floor under that. A seed entry is an address and an encryption key. Deliberately no meeting node: the rendezvous relay pairs on the service's public key, and a `.btf` address is that key, so a client can find a seed by trying the known relays in turn.

Seeds carry no authority. They serve the same signed, self-certifying descriptors as any peer, so a hostile seed can stall a bootstrap but cannot forge a peer or feed a false chain. The compiled list is empty. Which nodes become permanent public bootstrap targets is a decision for whoever runs the network, not a default, and it is close to irreversible once binaries are distributed.

The dynamic loader resolves every dependency before main() runs, so the flag arrives far too late -- on a clean server the binary dies with error while loading shared libraries: libGL.so.1: cannot open shared object file and nothing suggests it would otherwise have worked. A server is where a node most naturally lives, so this is the deployment that mattered most and the one that failed. The AppImage additionally needs FUSE, which minimal servers lack. Bundling libGL into the AppImage would be the wrong fix: GL has to come from the host's driver stack, and shipping our own breaks machines that have a real GPU. So: a second binary, built from the same node objects without ImGui, GLFW or OpenGL. `make linux-node` produces bitflash-node--x86_64, 2.5 MB stripped, with no graphics or FUSE dependency at all. `make linux` now builds it alongside the AppImage. Anyone wanting a window keeps using the AppImage. Two small moves were needed. MainFrameRepaint is called from main.cpp and net.cpp but defined in gui.cpp, so headless.cpp provides an empty one rather than putting ifdefs at six call sites. DateTimeStr also lived in gui.cpp while main.cpp logs block times with it -- nothing about formatting a date is GUI work, so it moved to util.cpp and both builds share one definition.

Nothing on the call path caught these, so the exception unwound into std::terminate -- surfacing on Windows as STATUS_STACK_BUFFER_OVERRUN (0xC0000409) with no useful message. Three layers of defense: 1. main_gui.cpp: try/catch around LoadBlockIndex() and LoadWallet(), printing the reason and exiting cleanly. 2. db.cpp LoadWallet: try/catch around the record-reading loop (Satoshi's 2009 TODO), tracking the last record type so the error message says what it choked on. 3. db.cpp cleanup paths: every dbenv.close(), pdb->close(), txn_checkpoint() and log_archive() wrapped in try/catch so the environment teardown after a failed open does not throw a second exception into std::terminate. Tested: cross-platform wallet (Linux BDB 5.3 → Windows 6.2) now prints a clear message and exits with code 1, wallet left untouched.

GCC and Clang define __GNUC__ on every architecture they target, so on aarch64 the guard passes and the assembler then rejects the instruction: Error: unknown mnemonic `bswap' -- `bswap %eax' This makes the tree fail to build on any ARM64 host -- Apple Silicon, ARM servers, a Raspberry Pi -- at a point far from anything the user did. Narrow the guard to the architectures where the instruction exists. The portable C fallback directly below is then used everywhere else; it was already there and already correct.

The node then ran indefinitely looking completely healthy -- it synced, it held peers, it reported no errors -- while earning nothing. Nothing in the log said otherwise; the only hint was `nMineMode = 0` in a startup line that reads like a status echo. This affects every headless miner, because the GUI is the only other way to select a mining mode. /gen now implies MINE_SOLO unless /operator or /participant asked for something else.

It killed the node mid-sync at the first block carrying a real transaction, deterministically. GCC can catch this. It never got the chance, for two reasons that had to be fixed together: - `-w` sat in both makefiles and suppressed every diagnostic. It cannot be narrowed; it wins over any -W or -Werror= that follows, so it had to go. The four -Wno- entries replacing it are the categories this 2009-era tree actually produces (measured: 248 deprecated-declarations, 157 write-strings, 18 narrowing, 1 unused-result), silenced by name instead of wholesale. - Even with -Wformat on, nothing was checked. GCC only inspects format strings for functions it knows are printf-like, and every format string here goes through strprintf, error, my_snprintf, or OutputDebugStringF -- `printf` itself is #defined to the last of those. None carried a format attribute, so the entire tree was invisible to the check. They are annotated now. Annotating surfaced 77 warnings across 17 distinct sites, all fixed here. Most were size_t or int64 passed to %d, harmless on x86-64 but wrong. Two were not cosmetic: - CBlockIndex::ToString printed pprev/pnext with %08x, truncating both pointers to 32 bits, so the two fields that line exists to show were unreliable on every 64-bit build. - CInv::GetCommand threw "type=% unknown type", where the % ate the space as a flag and the u as its conversion. The message read "type= 3nknown type". PRId64 is now one spelling for every target. Its MSVCRT branch was what produced "I64d" in the first place, it is pointless against UCRT which takes the C99 forms, the rest of the tree already prints int64 with %lld on Windows, and its only user (i64tostr) is dead code. Collapsing it lets both builds share the gnu_printf archetype -- ms_printf would reject %zu, which this tree uses and UCRT supports, while waving through the %I64d that crashes. Verified on both platforms: clean build, and reintroducing the issue #5 specifier now fails compilation rather than shipping. main.h:410:50: error: unknown conversion type character 'I' in format main.h:410:70: error: format '%s' expects argument of type 'char*', but argument 3 has type 'long long int' That second line is the crash itself, caught at build time. Runtime checked on both: node syncs past the block from issue #5, and the repaired log lines read correctly -- before: CTxOut(nValue= 50.%08I64d, scriptPubKey=(null)) after: CTxOut(nValue=50.00000000, scriptPubKey=0xE1C7EF3E706002) Four '_WIN32_WINNT redefined' warnings remain on Windows. Silencing them means letting a system header pick the Windows API level instead of this tree, which is a separate decision from format checking. --- src/Makefile | 21 ++++++++++++++++++++- src/btfaddr.cpp | 3 +++ src/main.cpp | 16 ++++++++-------- src/main.h | 14 ++++++++------ src/makefile.mingw | 9 ++++++++- src/net.cpp | 2 +- src/net.h | 4 +++- src/nostr.cpp | 6 +++++- src/util.cpp | 4 ++-- src/util.h | 44 ++++++++++++++++++++++++++++++++++---------- 10 files changed, 92 insertions(+), 31 deletions(-) (limited to 'src') diff --git a/src/Makefile b/src/Makefile index 9846d8e..f0c6706 100644 --- a/src/Makefile +++ b/src/Makefile @@ -9,7 +9,26 @@ RANDOMX_DIR ?= $(HOME)/RandomX IMGUI_DIR = imgui -CXXFLAGS = -std=gnu++14 -O2 -w -fpermissive -pthread \ +# -w used to sit here and suppressed every diagnostic in the build, including +# the one that mattered: `%I64d` is MSVC-only, glibc mis-parses it as the GNU +# `I` flag with a width of 64 and an `int` conversion, and the resulting vararg +# desynchronisation segfaulted the node while logging a received block (issue +# #5, deterministic at height 1062 -- the first block carrying a real +# transaction).

The file is intact -- same bytes, same keys -- and the node refuses it with "Db::put: Invalid argument", thrown from a path that aborted the process. The reporter believes they lost funds to this, having saved the one file anybody would think to save. The chain, from the bottom: _endthread() is pthread_exit() on POSIX, and glibc implements that by throwing abi::__forced_unwind through the stack. That is not a real exception; catching it without rethrowing is a fatal error by contract. CATCH_PRINT_EXCEPTION ended in a bare catch(...), so every Linux shutdown ended: UNKNOWN EXCEPTION bitflash-node in ThreadSocketHandler() FATAL: exception not rethrown An abort, mid-shutdown, so nothing after StopNode() ran. Which mattered because Berkeley DB stamps every page with a log sequence number belonging to the environment that wrote it. Carried elsewhere, those numbers point at logs that do not exist and BDB refuses to write. DBFlush(true) calls lsn_reset, which is precisely the cure -- and DBFlush has been declared since 2009 and called from nowhere. Even had it been called, the abort stood in front of it. So the wallet was never released from its directory, and the one file users copy was the one file that could not travel. Three fixes, each covering a different case: - Rethrow abi::__forced_unwind, and call DBFlush(true) on both shutdown paths. Shutdown completes, and wallet.dat is left portable by construction. - Adopt orphaned files on open: a freshly created database environment beside pre-existing .dat files means they came from elsewhere, so reset their sequence numbers. This is what recovers wallets already stranded by older builds -- including, if they still hold the file, the reporter's. - BackupWallet(), reachable as /backupwallet=FILE, which checkpoints, copies, and clears the copy's sequence numbers. Bitcoin 0.1.0 had a backup command; this tree lost it in the wxWidgets removal and has shipped with no way to take a backup since. DBFlush's own txn_checkpoint and lsn_reset are wrapped too -- they throw, and throwing on the way out is how this started. Verified on Linux and Windows: shutdown exits 0 rather than 134, DBFlush runs, and a lone wallet.dat opens in an empty directory with no exceptions and byte-identical key records (defaultkey, key, name, setting, version) before and after. Not addressed here, and the larger half of #40: keys are generated as they are needed rather than derived from a seed, so any backup is a snapshot and coins paid to addresses created after it are not in it. /backupwallet says so on every run. The real answer is deterministic derivation, which is a wallet format change and its own piece of work. * README: document what a wallet backup actually requires The PR description claimed this section existed and it did not. Covers the two things that cost money and are not obvious: a lone wallet.dat is refused elsewhere because Berkeley DB ties it to the database/ directory beside it, and every backup is a snapshot because keys are made on demand rather than derived from a seed. --- README.md | 31 +++++++++++++ src/db.cpp | 134 +++++++++++++++++++++++++++++++++++++++++++++++++++++-- src/db.h | 6 +++ src/main_gui.cpp | 32 +++++++++++++ src/util.h | 32 +++++++++++++ 5 files changed, 232 insertions(+), 3 deletions(-) (limited to 'src') diff --git a/README.md b/README.md index 1720c46..da8183a 100644 --- a/README.md +++ b/README.md @@ -69,6 +69,37 @@ backup — it holds your keys. --- +## Backing up your wallet + +Two things about this wallet will cost you money if you do not know them.

Everything else assumes Berkeley DB will cooperate. When it will not -- a build that cannot read the file, a truncation, an environment past recovering -- the keys are usually still perfectly intact and were unreachable anyway. #40 is one person's account of exactly that, and #46 only rescues the cases where BDB still opens the file at all. bitflash -dumpwallet=keys.txt bitflash -importwallet=keys.txt One key per line with its address and label. No database, no environment, no version coupling: anything that can read a line can recover from it. The format is the DER private key in hex, which round-trips exactly through SetPrivKey. Not interchangeable with other wallets -- worth having eventually, but a WIF encoder I got subtly wrong would be worse than no encoder at all, and this file exists for the case where nothing else works. Care taken, because the failure modes here cost money: - Refuses to overwrite an existing file. A mistyped path must not eat the only copy of something irreplaceable. - Written owner-only on POSIX, before any key reaches it. Windows inherits the folder's ACL; the README says so rather than pretending otherwise. - Newlines in labels are flattened, so a label cannot forge an extra entry on read-back. - Import skips keys already present, so running it twice does nothing, and one unreadable line is reported and stepped over instead of costing the reader every other key in the file. Verified on Linux and Windows: a key exported from one wallet imports into a different one and its address then appears there; re-importing adds nothing; a corrupted line is skipped while the rest still load; the dump is 0600 and refuses to overwrite. This does not solve #47. Keys still are not derived from a seed, so a dump is as much a snapshot as any other backup. What it does is make the keys reachable no matter what state the database is in. --- README.md | 24 +++++++ src/db.cpp | 191 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ src/db.h | 7 ++ src/main_gui.cpp | 33 ++++++++++ 4 files changed, 255 insertions(+) (limited to 'src') diff --git a/README.md b/README.md index da8183a..16e979f 100644 --- a/README.md +++ b/README.md @@ -98,6 +98,30 @@ The second point is the pre-BIP32 problem that deterministic wallets were invented to solve; see [#47](https://github.com/Bitflash-sh/bitflash/issues/47).

The wait had no bound, and ConnectTo() clears the socket timeout on purpose -- a registration is idle by design and may sit for a long time. What that cannot survive is the path dying with neither end saying so, which is the ordinary case and not the exotic one: a NAT drops the idle mapping, a relay restarts, a route changes. No FIN arrives, nothing becomes readable, and recv() never returns. The thread stays alive and asleep, so ThreadBtfAccept never reaches the `continue` that would register again. The node is unreachable and every outward sign says it is fine. Caught on the bootstrap seed: 27 minutes without a block, eight behind the network, relay reachable the whole time, and a restart fixing it instantly. Nothing in the log marked the moment it went deaf. I tried TCP keepalive first and it does not work here. With probes every 5s and a 2-probe limit, a socket whose replies were being dropped was still ESTAB after four minutes with the probe counter stuck at zero. It is measured, not assumed, and that approach is not in this change. So the bound is ours to enforce, at the one place that knows what waiting means. RvServiceWaitPaired takes a timeout; expiring is not an error but "nobody came, go round again", which the loop above already handles. Cost is one reconnect per relay per five minutes. Verified by killing a registration's path silently -- dropping only the relay's replies, so no RST or FIN is ever seen. With a 60s bound for the test: rendezvous: no dial at 92.246.128.180:8434 within 60s (or it dropped us), re-registering Registrations went 1 -> 2 and the node carried on. Before this, the same treatment left it blocked past four minutes with no log line at all. The socket goes back to blocking once a dial lands, because from that point it is a data tunnel and a tunnel is allowed to sit quiet between messages. --- src/btfrv.cpp | 51 +++++++++++++++++++++++++++++++++++++++++++++++++-- src/btfrv.h | 7 ++++++- src/net.cpp | 13 +++++++++---- src/net.h | 8 ++++++++ 4 files changed, 72 insertions(+), 7 deletions(-) (limited to 'src') diff --git a/src/btfrv.cpp b/src/btfrv.cpp index 63e092e..7efd38b 100644 --- a/src/btfrv.cpp +++ b/src/btfrv.cpp @@ -258,10 +258,57 @@ RvSocket RvServiceRegister(const char* relay_host, unsigned short port, return (RvSocket)s; } -bool RvServiceWaitPaired(RvSocket s) +bool RvServiceWaitPaired(RvSocket s, int nTimeoutSecs) { + // A registration socket is idle on purpose -- we announce ourselves and + // wait, possibly for a long time, for someone to dial.

SHA-256d on a 2009 desktop lost little to a single thread. RandomX is built to be fed by every core at once, so one thread on a 32-core machine mines at a thirty-second of what the box can do -- and the only outward sign is a CPU that looks suspiciously idle. A user reported exactly that: 30 minutes of "Mining", no blocks, Bitflash sitting at 3.3% CPU while the 2 GB dataset was allocated and fast mode was active. Nothing was broken. It was hashing on one core. bitflash -gen # every core but one bitflash -gen -genproclimit=8 # exactly eight Automatic leaves one core to the rest of the node -- accepting blocks, talking to peers, drawing the window -- because a node that mines beautifully while falling behind the chain has won nothing. /genproclimit overrides it, and a count several times the core count is refused rather than quietly thrashing. The wrapper was already built for this: RandomXCreateMinerVM says "own VM, not shared", and the ~2 GB dataset is one allocation every thread reads. Only the 2 MB scratchpad multiplies, so sixteen threads cost about 32 MB more than one. The startup line says so, because "why is it using 2 GB" is the first question anyone asks. Two things had to be right for this to be safe: - Shutdown. Miners share slot 3 of vfThreadRunning and StopNode waits for every slot before DBFlush tears the database down. With several, the first one out announced that everyone had finished while the rest were still calling ProcessBlock, so they are counted now and only the last one clears the flag. The three CheckForShutdown(3) calls inside the miner became plain returns: _endthread() does not unwind on Windows, so the bookkeeping would have been skipped there. - Duplicated work. Each thread makes its own key, and the coinbase pays it, so every thread has a different merkle root and searches a different space. Block assembly was already under cs_main and cs_mapTransactions; AddKey and ProcessBlock take their own locks. Verified on both platforms: four distinct thread ids reach the hashing loop and all report back on shutdown, which exits 0 with DBFlush running. Auto picks cores-1 (1 on a 2-core box, correctly reported). Speedup itself needs a many-core machine to show and has not been measured here -- the claim in this message is about threads doing work, not a benchmark. Not touched: RandomX's memory. RANDOMX_DATASET_BASE_SIZE and SCRATCHPAD_L3 are part of the hash function, so a knob for "use more RAM" would either do nothing or fork the chain. Threads are the only real dial. --- src/gui.cpp | 3 ++- src/main.cpp | 51 +++++++++++++++++++++++++++++++++++++++++++------ src/main.h | 8 +++++++- src/main_gui.cpp | 25 ++++++++++++++++++++++-- src/net.cpp | 58 ++++++++++++++++++++++++++++++++++++++++++++++++++------ src/net.h | 2 ++ 6 files changed, 131 insertions(+), 16 deletions(-) (limited to 'src') diff --git a/src/gui.cpp b/src/gui.cpp index fc6f1e1..825202b 100644 --- a/src/gui.cpp +++ b/src/gui.cpp @@ -32,6 +32,7 @@ int64 GetBalance(); string PubKeyToAddress(const std::vector& vchPubKey); bool AddressToHash160(const std::string& str, uint160& hash160Ret); void ThreadBitcoinMiner(void*); +int StartMinerThreads(); void ThreadRPCServer(void*); // --------------------------------------------------------------------------- @@ -762,7 +763,7 @@ static void DrawOptionsDialog() fGenerateBitcoins = 0; } else { fGenerateBitcoins = 1; - if (!vfThreadRunning[3]) _beginthread(ThreadBitcoinMiner, 0, NULL); + if (!vfThreadRunning[3]) StartMinerThreads(); } if (nMineMode == MINE_OPERATOR) { diff --git a/src/main.cpp b/src/main.cpp index c882b0b..d4fc6d0 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -72,6 +72,13 @@ bool fSoloMineTest = false; // /solomine: mine without requiring a peer (local t // Settings int fGenerateBitcoins; +// How many threads to hash with. 0 means "decide from the hardware" -- see +// MinerThreadCount().

Nothing becomes readable, no error is raised, and the node simply stops hearing from that peer while the socket looks perfectly healthy. #51 bounded this for the rendezvous registration; the connection that comes out of the rendezvous had the same hole, and so did every ordinary peer. Stamp nLastRecv and nLastSend on the socket path and act on them: - nothing at all within 60s of connecting, disconnect. In testing this fired twice per run against dead .btf descriptors handed out by the relay, which is where the ghosts have been coming from. - queued to send for 10 minutes with nothing going out, disconnect. - nothing received for 30 minutes, disconnect. A healthy peer relays a block inventory about every two minutes, so this is fifteen intervals of silence. Bitcoin used ninety minutes against ten-minute blocks. Disconnecting is the whole cure: reconnection already works, and a peer we cannot hear is worth what no peer is worth. A node with nothing to relay would now look dead to a peer applying the same rule, so send "ping" after ten minutes of having said nothing. It carries no payload and expects no answer -- arriving is the entire content, because the receive path has already stamped nLastRecv by the time it is parsed. Requiring an answer would have read every node predating this change as dead, since those ignore unknown commands rather than replying.

What it did not add was a ceiling on how many items there can be, so a script still pays for itself once, in bytes, and then multiplies: 520 bytes per stack entry means a script of N bytes made almost entirely of OP_DUP occupies roughly 520N in memory, on every node that validates it. Two limits, both from Bitcoin: - at most 201 operations per script, counted outside the fExec test so the cost of a script cannot depend on which branch a signature happens to take. Pushes are exempt, being already bounded by the script length and by MAX_SCRIPT_ELEMENT_SIZE. - at most 1000 entries across both stacks together, counted together because OP_TOALTSTACK would otherwise move the problem rather than solve it. This tightens validation, so a node that does not upgrade accepts a superset of what this one accepts and is not stranded.

The version message carries no height -- 0.1.0 never had the field and this fork inherited the gap -- so the only evidence of a problem is a number on screen that stopped moving, which looks the same as a network with nothing to report. It is the structural reason a broken node here has always been indistinguishable from an idle one. Append nBestHeight to the version message and keep what a peer announced in CNode::nStartingHeight. The field goes last, so a node that predates it stops reading after addr and treats the rest as trailing bytes, which cost it one log line. Reading it is guarded by vRecv.empty() and never required: peers that do not send it keep nStartingHeight at -1 and are left out of the median. Every release so far sends the short form. GetPeerMedianHeight() takes the median rather than the maximum so a single peer claiming an absurd height cannot move it. Then use it. After five minutes more than one block behind the peer median, the node says so in the log -- not behind a debug category, because an operator who already enabled -debug is not the one who needs telling -- and the GUI carries the same sentence in its status area. "8 blocks behind for 27 minutes" is something a user can act on; a frozen counter is not. Verified against two nodes on the live network: the one starting from an empty datadir read its peer at 3797, reported 2636 then 1274 then 433 blocks behind as it caught up, and went quiet on its own once level. The other logged "peer height = -1" for the older nodes it met on the real network, which is the compatibility path doing its job. Known limit: nStartingHeight is a snapshot from handshake time and goes stale on a long-lived connection, so this catches a node that is receiving something but not blocks, not one that has gone completely deaf. The inactivity timeout from #55 covers that case and refreshes these heights when it forces the reconnect. --- src/gui.cpp | 10 ++++++++++ src/main.cpp | 8 +++++++- src/net.cpp | 61 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ src/net.h | 42 ++++++++++++++++++++++++++++++++++++++++- 4 files changed, 119 insertions(+), 2 deletions(-) (limited to 'src') diff --git a/src/gui.cpp b/src/gui.cpp index 825202b..28f5ffa 100644 --- a/src/gui.cpp +++ b/src/gui.cpp @@ -26,6 +26,7 @@ extern CAddress addrLocalHost; void MainFrameRepaint(); int GetDiscoveredPeerCount(); +int GetPeerMedianHeight(); string DateTimeStr(int64 nTime); bool SendMoney(CScript scriptPubKey, int64 nValue, CWalletTx& wtxNew); int64 GetBalance(); @@ -238,6 +239,15 @@ static void DrawStatusBar() connected, discovered, nBestHeight); } + // A node that has stopped receiving looks exactly like one with nothing to + // do.

It kept the branch, kept building on it, and kept mining coins the rest of the network throws away. The only cure was deleting blk*.dat by hand, which requires knowing something is wrong. A node here once mined a 323-block fork for five days that way. On load, walk back from the tip running CheckBlock on each block. If one fails, move the best chain back to its parent, disconnect what came after, and let the node re-download from peers. Satoshi added this after the block 74638 incident for the same reason: so it would not have needed anyone to delete files. Only the last 288 blocks are checked by default -- about ten hours at a two-minute target -- because every check costs a RandomX hash. /checkblocks=N changes it, 0 does the whole chain. The repair deliberately runs in LoadBlockIndex() in main.cpp rather than in CTxDB::LoadBlockIndex where the detection happens. CTxDB::LoadBlockIndex walks the index with a cursor it never closes, so it still holds read locks when it returns, and a write transaction opened alongside it waits on them forever. That is measured, not guessed: the first version came up, printed the diagnosis, and hung with nothing in any log. Closing that cursor is a separate fix worth making on its own. A failed rollback reports and starts anyway. Refusing to start would leave the operator with no node to read the message from. What this catches is what CheckBlock catches: proof of work, merkle root, duplicate transactions, sigops, timestamps. It does not re-verify signatures or spends, which would mean rebuilding the transaction index. Verified by forcing a block at tip-5 to fail: the node reported the bad block, moved back six, stayed up, and re-synced past its old tip. Without the forced failure it verifies 288 and says so. --- src/db.cpp | 41 +++++++++++++++++++++++++++++++ src/main.cpp | 75 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ src/main.h | 2 ++ src/main_gui.cpp | 5 ++++ 4 files changed, 123 insertions(+) (limited to 'src') diff --git a/src/db.cpp b/src/db.cpp index 4cc54ac..ce7b875 100644 --- a/src/db.cpp +++ b/src/db.cpp @@ -435,6 +435,47 @@ bool CTxDB::LoadBlockIndex() nBestHeight = pindexBest->nHeight; printf("LoadBlockIndex(): hashBestChain=%s height=%d\n", hashBestChain.ToString().substr(0,14).c_str(), nBestHeight); + // Verify the tail of the best chain, and fall back to the last good block + // if any of it fails. + // + // A node that accepted blocks its current rules would reject -- because it + // was running an older build, or because the tip it landed on was never + // valid -- has no way to notice on its own.

The correcting branch itself is NOT exercised by a real case: on this chain no test wallet holds a transaction that is both in the transaction index and spent, and the counters show why -- all 17 were absent from the index, so the comparison never had anything to compare. --- src/main.cpp | 65 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ src/main.h | 2 ++ src/main_gui.cpp | 4 ++++ 3 files changed, 71 insertions(+) (limited to 'src') diff --git a/src/main.cpp b/src/main.cpp index dbb2c41..85f89d9 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -693,6 +693,71 @@ bool CWalletTx::AcceptWalletTransaction(CTxDB& txdb, bool fCheckInputs) return true; } +int RescanSpentFlags() +{ + // Believe the chain, not the wallet, about what has already been spent. + // + // fSpent lives in wallet.dat and is written when this node spends + // something.

Its only guard is g_fFast, which is set at the very end -- after the ~2 GB dataset has been filled, which takes tens of seconds. So all of them sailed past the guard together and each allocated its own dataset. Measured in production on a 32-core machine running 31 miner threads: the log says "initializing ~2 GB dataset" 34 times, and the process holds 65,127 MB of private pages while its own startup line promises 2142 MB "(~2080 MB shared RandomX dataset + ~2 MB per thread)". The word shared was not true. A 4-core machine showed the same thing at its own scale: 4 allocations for 3 threads. The waste was the mild half. g_dataset is assigned the moment memory is allocated, before it holds anything, so the last thread to allocate swung the pointer out from under threads still filling their own. A miner could then hash against a dataset another thread had not finished writing, and proof of work computed that way is not reproducible by any other node -- the block would be found invalid by everyone, including this node's own verifier, which uses the cache rather than the dataset. This only became reachable with multi-threaded mining (#52); with one thread there was nobody to race. Holding the lock across the whole initialisation is deliberate: a thread arriving mid-init has nothing useful to do until the dataset exists, and blocking is how it waits for exactly that. Verified with three mining threads: one "initializing ~2 GB dataset", one "dataset ready", and 2362 MB of private memory against 2086 MB advertised -- the difference being the 256 MB cache.

Measured on a 32-core production node: 1287 of 4117 processed blocks arrived with a missing parent, 97 arrived that the node already had, and 490 transactions arrived whose inputs were unknown. mapOrphanBlocks had no ceiling at all. Orphan transactions have had one since 0.1.0 -- MAX_ORPHAN_TRANSACTIONS with LimitOrphanTx -- and blocks never did. An orphan block whose parent never turns up stays in memory for the life of the process, each one holding a whole block, and a peer can send an unlimited number of them just by inventing the previous-block hash. LimitOrphanBlocks mirrors the transaction one: random eviction, both maps kept in step, and the CBlock deleted because mapOrphanBlocks owns it. Every orphan block also fired a getblocks at the sender, and an inv for a block already held as an orphan fired another, with no filtering. So a node missing part of the chain asked the same peer the same question over and over, and the duplicate answers made more orphans, which asked again. CNode::PushGetBlocks remembers the last request and drops a repeat -- the same fix Bitcoin made in e2c2648c1. One trap found by testing rather than by reading: eviction picks at random and may pick the block just inserted, so GetOrphanRoot has to be read out of pblock before LimitOrphanBlocks runs, not after. The first version had that backwards and would have read freed memory. Verified with fabricated orphans, four of the seven sharing one hashPrevBlock so the multimap path is exercised: 7 in, limit(3) leaves 3, limit(0) leaves 0, both maps in step at every stage, no crash. Then a run against the live network to 4348 with no scaffolding left behind. The storm itself was not reproducible on demand -- the network is healthy today and produced one orphan block in seven minutes -- so there is no before/after on the metric that motivated this. --- src/main.cpp | 50 +++++++++++++++++++++++++++++++++++++++++++++++--- src/main.h | 9 +++++++++ src/net.cpp | 11 +++++++++++ src/net.h | 26 ++++++++++++++++++++++++++ 4 files changed, 93 insertions(+), 3 deletions(-) (limited to 'src') diff --git a/src/main.cpp b/src/main.cpp index b147ddd..4bc9c4d 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -293,6 +293,43 @@ void AddOrphanTx(const CDataStream& vMsg) // grow this map until the node runs out of memory.

Keep nValue meaning what the payee asked for and carry nValue + nFee in a separate nTotalValue, the way Bitcoin fixed it in 107d9e288. Verified by building the same transaction on both versions, with a synthetic wallet of 200 coins of 50, a configured fee of 0.05, and a request of 5,000 that needs 101 inputs and 28 KB -- enough for GetMinFee to demand 0.12 and force the retry: before payee gets 5,000.05 change 49.83 after payee gets 5,000.00 change 49.88 Two other fixes from the same era were considered and left out. Satoshi's CENT floor on the change output (496823249) exists to avoid a dust output that his fee rules then penalised; this fee schedule has no such rule, so adopting it would only donate sub-cent change to the miner. The 1-confirmation rule (a790fa46f) is a spending-policy change, not a bug fix, and deserves its own decision. --- src/main.cpp | 26 ++++++++++++++++++++------ 1 file changed, 20 insertions(+), 6 deletions(-) (limited to 'src') diff --git a/src/main.cpp b/src/main.cpp index c3fb33b..5610de9 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -3437,22 +3437,36 @@ bool CreateTransaction(CScript scriptPubKey, int64 nValue, CWalletTx& wtxNew, in wtxNew.vout.clear(); if (nValue < 0) return false; - int64 nValueOut = nValue; - nValue += nFee; + + // nValue is the amount the payee asked for and must stay that. + // + // This used to read "nValueOut = nValue; nValue += nFee;", and + // both lines are inside the retry loop.

FD_SETSIZE was never defined in this tree, so it defaulted to 64 and select() could watch the listen socket plus 63 peers -- everything past that stayed connected and was never read again. Windows FD_SET stops adding once its array is full and says nothing, so there was no error to notice. Because new connections go on the end of vNodes, it was always the newest connection that starved, including the ones dialed to fix connectivity. Measured on two nodes: 277 and 90 CNode objects against 93 and 90 live sockets, 316 and 355 sockets in a bound-but-never-connected state, and a status bar reporting hundreds of peers for a node really talking to thirty. 1.2.11 raises FD_SETSIZE to 1024 on Windows, caps connections at 125, drops a node stuck undeliverable after 60 seconds instead of holding it forever, stops answering a failed select() with POSIX code that has no meaning on Windows, and warns when there are more peers than select can watch. * diag: let the node say what is wrong with it Every hard problem in this project so far was found from outside the node -- sockets read over WMI, committed memory compared against a README, a grep over somebody debug.log. In each case the node knew and had no way to say so. One report, rendered identically for the GUI panel and the log: peers held vs peers actually watched by select(), blocks received and how many arrived without a parent, proof-of-work mode with the live miner thread count, and per peer the age of the last message in each direction plus anything stuck unsent. --- Makefile | 2 +- src/gui.cpp | 38 +++++++++++++++++++ src/main.cpp | 7 ++++ src/net.cpp | 117 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ src/net.h | 19 ++++++++++ 5 files changed, 182 insertions(+), 1 deletion(-) (limited to 'src') diff --git a/Makefile b/Makefile index d436885..0bc5892 100644 --- a/Makefile +++ b/Makefile @@ -8,7 +8,7 @@ ROOT := $(shell pwd) NPROC := $(shell nproc 2>/dev/null || echo 2) SUDO := $(shell [ "$$(id -u)" = "0" ] && echo "" || echo "sudo") -VERSION := 1.2.10 +VERSION := 1.2.11 # ---- Linux ---------------------------------------------------------------- diff --git a/src/gui.cpp b/src/gui.cpp index 53cb6db..db6b69e 100644 --- a/src/gui.cpp +++ b/src/gui.cpp @@ -50,6 +50,7 @@ static int64 g_lastWalletRefresh = 0; static bool g_showSend = false; static bool g_showOptions = false; static bool g_showAbout = false; +static bool g_showDiagnostics = false; static bool g_needRefresh = true; static char g_sendAddr[128] = {}; @@ -310,6 +311,7 @@ static void DrawMainWindow() ImGui::EndMenu(); } if (ImGui::MenuItem("Options")) g_showOptions = true; + if (ImGui::MenuItem("Diagnostics")) g_showDiagnostics = true; if (ImGui::MenuItem("About")) g_showAbout = true; ImGui::EndMenuBar(); } @@ -815,6 +817,41 @@ static void DrawOptionsDialog() // --------------------------------------------------------------------------- // About dialog // --------------------------------------------------------------------------- +// What the node knows about itself, in the words it writes to the log.

Reading the code did not find it: every connect() failure path here closes its socket. So count. Every socket is tagged at creation and untagged at close, across all ten sites, with a counter for closes that fail. Already rules out three explanations: nothing is created or closed behind the counter (untagged closes are zero), no close is failing, and the leaked sockets are not in the live set -- tracked live matches what the OS reports as established, while the bound pile is something the program already closed successfully. --- src/btfrv.cpp | 12 +++-- src/btftunnel.cpp | 23 ++++----- src/net.cpp | 43 ++++++++++++++--- src/net.h | 2 + src/nostr.cpp | 6 +-- src/rpc.cpp | 4 +- src/sockcount.h | 137 ++++++++++++++++++++++++++++++++++++++++++++++++++++++ 7 files changed, 199 insertions(+), 28 deletions(-) create mode 100644 src/sockcount.h (limited to 'src') diff --git a/src/btfrv.cpp b/src/btfrv.cpp index 7efd38b..6ac3280 100644 --- a/src/btfrv.cpp +++ b/src/btfrv.cpp @@ -11,7 +11,7 @@ #ifdef _WIN32 #include #include -#define CLOSESOCK closesocket +#define CLOSESOCK BtfCloseSocket #else #include #include @@ -22,12 +22,14 @@ typedef int SOCKET;

Verified here: clean rebuild, all self-tests pass, lock order checked (no path takes cs_keyPool before cs_mapWallet), and a node built from this branch synced from genesis to the chain tip on the live network with zero rejections. --- src/Makefile | 1 + src/main.cpp | 104 +++++++++++++++++++++++++++++++++++++++++++++-------- src/makefile.mingw | 1 + src/net.h | 15 +++++++- src/selftest.cpp | 65 ++++++++++++++++++++++++++++++++- src/walletcmd.cpp | 7 +++- 6 files changed, 176 insertions(+), 17 deletions(-) (limited to 'src') diff --git a/src/Makefile b/src/Makefile index 5ded7d6..88dc08f 100644 --- a/src/Makefile +++ b/src/Makefile @@ -139,3 +139,4 @@ tests: test_bip32 bitflash-node ./test_bip32 ./bitflash-node -selftest=wallet-keypool ./bitflash-node -selftest=wallet-hd + ./bitflash-node -selftest=net-message diff --git a/src/main.cpp b/src/main.cpp index 9082bd5..9bb3c24 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -181,6 +181,39 @@ static bool AddKeyIfMissing(const CKey& key) return AddKey(key); } +static bool DeriveNextHDWalletKey(vector& vchPubKeyRet, string& strErrorRet) +{ + vchPubKeyRet.clear(); + CRITICAL_BLOCK(cs_keyPool) + { + if (!HaveHDSeed()) + { + strErrorRet = "no seed"; + return false; + } + + CKey key; + if (!DeriveHDKey(nHDNext, key, strErrorRet)) + return false; + if (!AddKeyIfMissing(key)) + { + strErrorRet = "could not write the derived key to wallet.dat"; + return false; + } + + unsigned int nNext = nHDNext + 1; + if (!CWalletDB().WriteHDNext(nNext)) + { + strErrorRet = "could not advance the derivation counter"; + return false; + } + + nHDNext = nNext; + vchPubKeyRet = key.GetPubKey(); + } + return true; +} + vector GenerateNewKey() { CKey key; @@ -2310,27 +2343,55 @@ bool ProcessMessages(CNode* pfrom) if (LogAcceptsCategory("net")) printf("\n\nPROCESSMESSAGE SKIPPED %d BYTES\n\n", (int)(pstart - vRecv.begin())); vRecv.erase(vRecv.begin(), pstart); - // Read header + // Read the header from a copy first.

The old build raises the assertion; the fixed build closes the dialog, reports "This wallet has a recovery phrase", and the address changes to a derived one. The seed itself was already written before the assertion, so the wallet was never left half-installed -- and ImGui's IM_ASSERT_USER_ERROR_RET returns before touching its state, so answering Ignore was safe. Abort was not: it kills the process with no DBFlush. The restore dialog next door already does this correctly, copying the condition into a local first. This makes the create dialog match. --- src/gui.cpp | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) (limited to 'src') diff --git a/src/gui.cpp b/src/gui.cpp index e800244..e3a8499 100644 --- a/src/gui.cpp +++ b/src/gui.cpp @@ -1005,7 +1005,15 @@ static void DrawCreatePhraseDialog() ImGui::Checkbox("I have written these words down", &g_phraseWrittenDown); ImGui::Spacing(); - if (!g_phraseWrittenDown) + // Read the condition once, before the button that changes it. + // + // Pressing Finish clears g_phraseWrittenDown, so testing it again after + // the click asked BeginDisabled and EndDisabled two different questions: + // the pair was opened while the checkbox was ticked and closed after the + // handler had unticked it.

Both were found against a wallet holding real coin, not in the self-tests. 1. Encrypting turned a BIP44 wallet into a legacy one. LoadWallet() ends by resetting the schema and the derivation counters when no seed is in memory. That was written when "no seed after loading" could only mean the wallet had none. An encrypted wallet has a seed -- it just has not been decrypted yet -- so the reset threw away metadata that had been read correctly a moment earlier. Unlocking later restores the seed and nothing restores the rest. Measured on the wallet from the #124 proof: after encrypting, index 1 moved off BAtgSgra2X8Dqo5PJzPCLJhPwrrC2thYVJ, the address actually holding 1.00 BTF, and the audit went from "1.00 covered by the phrase" to "0.00 covered, 1.00 wallet.dat-only". Encrypt your wallet and the program told you your recovery phrase no longer covered your money. Now the condition also accepts a wallet whose seed is present but encrypted. Same wallet, before and after: schema bip44, same four derived addresses, 1.00 BTF still reported as covered. 2. The plaintext keys stayed behind in the Berkeley DB logs. wallet.dat comes out clean -- verified by scanning the raw file for the 118 bytes of a known private key. database/log.0000000002 did not: it held the whole key, and still did after a full node restart, because every record this wallet ever wrote passed through the log. That defeats the feature for the case it exists for, since our own backup advice is to copy the whole directory rather than wallet.dat alone. log_archive() cannot fix it: it only drops logs Berkeley DB considers obsolete and never the one it is writing to, and with one 10 MB log per directory that is precisely where the keys are. They also did not get there at encryption time -- they accumulated over the wallet's whole life -- so nothing done during the rewrite can archive them out. So the encrypt command now closes the environment and deletes the logs on its way out, after the flush that makes every .dat self-contained. This is not secure erasure; the blocks are unlinked, not overwritten. It closes the case of someone reading a copied data directory. Getting there uncovered a third bug, older than both. DBFlush(true) is not safe to call twice. The first call closes the environment, and txn_checkpoint() on a closed environment segfaults instead of returning an error, so the try/catch around it never sees anything. EncryptWallet() already flushes before renaming the wallet, and the command flushes again on the way out -- that pair crashed every single time. Guarded now. The same function has been calling log_archive() with the address of an uninitialised pointer since 0.1.0, on every clean shutdown, in a path whose catch(...) cannot catch a structured fault on Windows. DB_ARCH_REMOVE requires that argument to be NULL. Fixed while here, because the encryption cleanup depends on that call not being a coin flip. --------- Co-authored-by: Gilcimar Duarte --- src/Makefile | 3 + src/db.cpp | 602 ++++++++++++++++++++++++++++++++++++++++++++++++++--- src/db.h | 58 ++++++ src/main.cpp | 334 ++++++++++++++++++++++++++++- src/main.h | 40 ++++ src/main_gui.cpp | 101 ++++++++- src/makefile.mingw | 3 + src/script.cpp | 89 ++++---- src/selftest.cpp | 504 +++++++++++++++++++++++++++++++++++++++++++- src/walletcmd.cpp | 36 ++++ src/walletcmd.h | 4 + 11 files changed, 1698 insertions(+), 76 deletions(-) (limited to 'src') diff --git a/src/Makefile b/src/Makefile index 82e7d06..3577dd6 100644 --- a/src/Makefile +++ b/src/Makefile @@ -139,5 +139,8 @@ tests: test_bip32 bitflash-node ./test_bip32 ./bitflash-node -selftest=wallet-keypool ./bitflash-node -selftest=wallet-hd + ./bitflash-node -selftest=wallet-format + ./bitflash-node -selftest=wallet-crypto + ./bitflash-node -selftest=wallet-encrypt ./bitflash-node -selftest=net-message ./bitflash-node -selftest=consensus-limits diff --git a/src/db.cpp b/src/db.cpp index b7e7b91..9334249 100644 --- a/src/db.cpp +++ b/src/db.cpp @@ -203,11 +203,72 @@ void CDB::Close() RandAddSeed(); } +// Close the Berkeley DB environment and delete its write-ahead logs. +// +// Encrypting the wallet rewrites wallet.dat, and that file does come out clean. +// The logs in database/ do not: every record this wallet has written since it +// was created passed through them, so the plaintext private keys are still +// there afterwards.

A -mwindows binary started by double-clicking has no stderr at all, and AttachTerminal() cannot help: it attaches to a parent console, which a double-clicked exe does not have. So Bitflash exited silently. Someone whose wallet.dat needs a newer build -- exactly what the wallet format guard was added to tell them -- double-clicked and watched nothing happen. The guard was correct and mute, which is the failure it was written to prevent. Fatal startup errors now go through one reporter: debug.log as before, stderr as before, and a message box when there is a person in front of the screen. Applied to the three that mean "your data will not open": the block index failing to load, the block index throwing, and wallet.dat failing or throwing. The box is deliberately not shown for a headless node. Those run under scheduled tasks and services, where a modal dialog waits forever for a click nobody is there to make -- a hung process instead of an exit code. Headless keeps stderr and the log. LoadWallet() now also reports why it refused, in a sentence, instead of only logging it. The unsupported-format case is the one that has to be understood by whoever reads it, and "LoadWallet failed" is not that. Verified by breaking a throwaway wallet on purpose and starting both ways. Headless: exit code 1, no dialog, no process left behind. Windowed with no console: a box naming the file, the Berkeley DB error, the usual cause, and where to look for more. --- src/db.cpp | 19 +++++++++---- src/db.h | 3 ++ src/main_gui.cpp | 87 +++++++++++++++++++++++++++++++++++++++++++++++++------- 3 files changed, 94 insertions(+), 15 deletions(-) (limited to 'src') diff --git a/src/db.cpp b/src/db.cpp index 9334249..c8642e9 100644 --- a/src/db.cpp +++ b/src/db.cpp @@ -48,6 +48,10 @@ private: static CCriticalSection cs_db; static bool fDbEnvInit = false; + +// Why LoadWallet() refused, in words meant for the person who has to act on it. +// Empty unless the reason is one we can name. +string strWalletLoadError; DbEnv dbenv(0u); static map mapFileUseCount; @@ -625,6 +629,7 @@ bool CWalletDB::LoadWallet(vector& vchDefaultKeyRet) bool fHaveStoredMineMode = false; bool fHaveStoredHDCoinType = false; vchDefaultKeyRet.clear(); + strWalletLoadError.clear(); // Satoshi's "todo: shouldn't we catch exceptions" sat here since 2009, and // it was not a nicety.

It is a separate path from BitcoinMiner() and had drifted from it. A single pass over mapTransactions is not enough. That map is keyed by hash and carries no dependency order, so a transaction spending another still-unconfirmed transaction's output -- change from a recent send, usually -- fails ConnectInputs whenever its parent sits later in map order. One pass drops it, and map order does not change between rebuilds, so every later rebuild drops it at the same point. That is deterministic exclusion rather than bad luck: where pool operators mine most blocks, a transaction of that shape can stay unconfirmed for as long as its parent is. Now it retries until a pass adds nothing, which is what the solo builder has always done. And the fees reached nobody. nFees was declared inside the scan loop, so each transaction reset it and the running total was discarded, while the coinbase line passed a hardcoded 0. An operator collected fees into a block and paid none of them out. The block stayed valid, since paying less than allowed always is, so nothing ever complained. Both the diagnosis and the fix are Vic-Nas's, from his fork of this code. He deleted the fork, so this brings the work back rather than letting it go with it. His description of the failure was precise enough that finding the same two defects here took one read of our RebuildJob. --- src/rpc.cpp | 61 ++++++++++++++++++++++++++++++++++++++++++++++++------------- 1 file changed, 48 insertions(+), 13 deletions(-) (limited to 'src') diff --git a/src/rpc.cpp b/src/rpc.cpp index 41c0328..d73b09c 100644 --- a/src/rpc.cpp +++ b/src/rpc.cpp @@ -167,29 +167,64 @@ static bool RebuildJob() CBlock block; block.vtx.push_back(txNew); + // Fill the block the same way BitcoinMiner() does, because this is the + // same job: a block that gets mined and submitted for real. + // + // It used to differ in two ways, and both were bugs. + // + // One pass over mapTransactions is not enough.

Under -walletbackend=sqlite that was wrong -- it would leave the live wallet.sqlite unencrypted and write a divergent wallet.dat instead. Add a SQLite persistence branch that rebuilds a fresh wallet.sqlite in one transaction (public records copied from the live store, encrypted key material serialized byte-for-byte the way the BDB path writes it), checkpoints it, and swaps it in with a .before-encrypt backup, mirroring the BDB rename dance. A fresh file rather than an in-place rewrite keeps the change atomic and leaves no plaintext key in a freed page. CmdEncryptWallet skips PurgeDbEnvironmentLogs under SQLite (no Berkeley DB environment behind the wallet) and reports the backend it used. New wallet-sqlite-encrypt self-test drives the real command path in child processes: export a wallet to SQLite, encrypt it through -walletbackend=sqlite, and prove it comes out encrypted, unlockable with the right passphrase, refusing the wrong one, with its recovery phrase intact and the original wallet.dat left untouched. --- src/db.cpp | 210 ++++++++++++++++++++++++++++++++++++++++++++++++++++- src/makefile.mingw | 1 + src/selftest.cpp | 189 ++++++++++++++++++++++++++++++++++++++++++++++- src/walletcmd.cpp | 15 +++- 4 files changed, 410 insertions(+), 5 deletions(-) (limited to 'src') diff --git a/src/db.cpp b/src/db.cpp index 771a4ba..86f6dd7 100644 --- a/src/db.cpp +++ b/src/db.cpp @@ -1974,9 +1974,9 @@ static bool CopyPublicWalletRecordsTo(CWalletRewriteDB& dbTo, return ScanWalletRecords(visitor, strErrorRet); } -static string WalletEncryptBackupPath() +static string WalletEncryptBackupPathFor(const char* pszBaseName) { - string strBase = GetAppDir() + "/wallet.dat.before-encrypt."; + string strBase = GetAppDir() + "/" + pszBaseName + ".before-encrypt."; string strPath = strBase + i64tostr(GetTime()) + ".bak"; for (int i = 1; FileExists(strPath.c_str()); i++) strPath = strBase + i64tostr(GetTime()) + "." + itostr(i) + ".bak"; @@ -2006,6 +2006,192 @@ static void SecureClearBytes(vector& vch) vch.clear(); } +// The SQLite counterpart of CWalletPublicRecordCopyVisitor: same skip list, +// same byte-for-byte copy, but the destination is a CWalletDBSQLite record +// store rather than a Berkeley DB file. +class CWalletPublicRecordCopyToSQLiteVisitor : public CWalletRecordVisitor +{ +public: + CWalletDBSQLite& dbTo; + int& nCopied; + + CWalletPublicRecordCopyToSQLiteVisitor(CWalletDBSQLite& dbToIn, int& nCopiedIn) + : dbTo(dbToIn), nCopied(nCopiedIn) { } + + bool VisitWalletRecord(const CDataStream& ssKey, + const CDataStream& ssValue, + string& strErrorRet) + { + string strType; + try + { + CDataStream ssType = ssKey; + ssType >> strType; + } + catch (...) + { + strErrorRet = "SQLite wallet has a record whose key type cannot be read"; + return false; + } + + if (IsWalletEncryptionPrivateRecord(strType)) + return true; + + vector vchKey(ssKey.begin(), ssKey.end()); + vector vchValue(ssValue.begin(), ssValue.end()); + bool fOk = dbTo.WriteRecord(vchKey, vchValue, strErrorRet, true); + if (!vchKey.empty()) + memset(&vchKey[0], 0, vchKey.size()); + if (!vchValue.empty()) + memset(&vchValue[0], 0, vchValue.size()); + if (!fOk) + { + strErrorRet = strprintf("could not copy wallet record '%s': %s", + strType.c_str(), strErrorRet.c_str()); + return false; + } + nCopied++; + return true; + } +}; + +// Persist an encrypted wallet under the SQLite backend.

The choice is recorded in a plain-text /wallet-backend marker so it survives a restart without a command-line flag. Backend resolution when no -walletbackend is given: an existing wallet.sqlite (or a "sqlite" marker) stays on SQLite; an existing wallet.dat stays on Berkeley DB -- nothing is converted behind the user; a fresh datadir starts on SQLite. An explicit -walletbackend=bdb or a "bdb" marker forces Berkeley DB and overrides the default. Adds CreateNewSQLiteWallet() (WalletSQLiteRuntimeOpen gains fMustExist so the create path can make a new file) which mints the first default key straight into the SQLite store via the same FinishLoadedWallet() call the Berkeley DB create path uses, then cleans up on failure. Marker read/write helpers are plain text, hand-editable. New wallet-backend-default self-test proves the resolution in child processes (fresh->SQLite+marker, existing wallet.dat->BDB, "bdb" marker->BDB, explicit flag->wallet.dat). The three wallet.dat-specific suites now ask for -walletbackend=bdb explicitly, since a flagless fresh datadir is SQLite now.

The conversion itself is DoConvertWalletToSQLite(), a headless-testable function the button calls: it reuses the export path (extracted as ExportActiveWalletToSQLite, shared with -walletsqliteexport, which keeps its own specific messages), refuses if already on SQLite or if a wallet.sqlite exists, and writes the marker only after a verified export. New wallet-convert self-test proves the action end to end: build a Berkeley DB wallet, convert, and confirm wallet.sqlite + the marker are written, wallet.dat is left untouched, a second convert refuses, and a flagless restart opens the converted SQLite wallet with its phrase intact. All wallet suites pass.

The post-conversion screen now offers "Restart Now", which relaunches Bitflash with the same command line and datadir (a short delay lets this instance release the network port and block-index files first) and asks this one to exit, so mining resumes on the SQLite wallet. "Later" keeps the old behaviour. A dimmed line warns that mining before the restart still credits the old wallet. wallet.dat is still never touched. The conversion action itself is unchanged (wallet-convert self-test still green); this is GUI wiring only. --- src/gui.cpp | 82 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++--- 1 file changed, 79 insertions(+), 3 deletions(-) (limited to 'src') diff --git a/src/gui.cpp b/src/gui.cpp index 89a7ab6..81dd8e0 100644 --- a/src/gui.cpp +++ b/src/gui.cpp @@ -11,6 +11,9 @@ #include #include #include +#ifndef _WIN32 +#include +#endif #include #include #include @@ -1400,6 +1403,67 @@ static void DrawAboutDialog() static bool g_showBackendWizard = false; static std::string g_wizardStatus; static bool g_wizardConverted = false; +static int g_restartArgc = 0; +static char** g_restartArgv = NULL; + +// Relaunch Bitflash with the same arguments and datadir, then ask this instance +// to exit.

The default now matches the live backend (.sqlite on SQLite, .dat on BDB). - The recovery audit called coins on non-phrase keys "wallet.dat-only" and told the user to "keep wallet.dat backups". Under SQLite those coins live in wallet.sqlite, not wallet.dat. Reworded to the backend-neutral truth: "not phrase-backed" balance, and "keep a file backup of this wallet" -- accurate on either backend.

Addresses the edge cases the review flagged, and drops the fragile batch layer entirely: - Windows no longer writes a .bat and shells through cmd (which re-parsed the arguments and could leave a stray file on failure). It builds the command line once, quoted correctly (only backslashes before a quote are doubled, so ordinary paths are not mangled), and CreateProcess launches the new instance directly. - The delay moved into the new instance: a -restartwait flag makes it wait ~2.5s before it opens the network port and the block index, so the old process is gone first. No shell delay hack. Verified: -restartwait adds the wait (0.16s -> 2.67s). - Linux re-execs /proc/self/exe (absolute) and only falls back to argv[0], which may be relative or a bare PATH name that execv cannot resolve. - This instance now exits only if the relaunch actually started; on failure it keeps running and tells the user to restart manually, so a failed relaunch never leaves them with no node.

It updated its own caller in net.cpp and left this one behind. AcceptOneFn went straight from RvServiceRegister to BtfServiceWrap, so BtfServiceWrap read that 0x01 as the first byte of the miner's 32-byte ephemeral key and every byte after it was shifted by one. The X25519 handshake has no confirmation step, so it completed against a garbage shared secret, the tunnel was handed to the Stratum event loop, and nothing failed loudly: the pool logged a miner arriving and then dropped it as "never authorized", while the miner logged a pool that closed on it with gotSubscribeAck=0. Loopback miners were unaffected, which is exactly what made it look like a relay problem. Block in RvServiceWaitPaired before wrapping, and close and re-register if the relay drops us first. test_rvaccept.cpp covers both shapes against a real bitflashd on loopback: the pre-fix order establishes a tunnel that carries no bytes, the fixed order round-trips. Also corrects the btftunnel.h contract comment, which still described the pre-#30 behaviour and is what the old code was written against -- upstream's own test_relayproc.cpp, test_btftunnel.cpp and test_btfrv.cpp are still on that stale contract and fail the same way.

That branch is taken when nValue + nFeeRequired > GetBalance() -- an empty spendable balance -- and the fee reads 0.00 because CreateTransaction failed before setting one. 3,267 of these in debug.log sent me looking for a transaction-size problem that does not exist. Report what is short, by how much, and against what balance. Name COINBASE_SPENDABLE_DEPTH in main.h and derive GetBlocksToMaturity from it, because the distinction it captures is genuinely surprising: CMerkleTx::GetCredit values a mined coinbase at zero until COINBASE_MATURITY+20 deep, not COINBASE_MATURITY. I first changed the payout gate to that deeper value, on the theory that each payout was firing 20 blocks before its own coinbase could be spent. Measuring it refuted that: across 934 payments, 96% succeeded at depth 100, the moment they were queued, which is only possible because a payout is funded from whatever coin is already mature rather than from its own block. The gate stays at COINBASE_MATURITY, with a comment recording the measurement so the next person does not re-make the same change. The real shortfall is structural and not addressed here: the pool pays out ~99% of each block's subsidy while only matured coinbases are spendable, so it runs with almost no buffer, and any orphaned block it queued a payout for drains that buffer permanently. The 24h retry loop absorbs this -- 0 payouts forfeited -- but the buffer is what needs fixing.

The payout ledger did not notice: it records only matureAtHeight, and a reorg replaces the block at a height without changing the height, so ~14.4k BTF of obligations outlived the coin that was supposed to fund them. The pool then paid fork-era miners out of real-chain coin until the wallet was empty -- 17,827 BTF paid against 17,900 BTF of matured supply, leaving under 1.1 BTF spendable and every subsequent payment failing. Three changes, all in the payout path: - Record the funding block's hash and height, persist both, and void an obligation whose block is no longer in the main chain. Checked both at maturity and again in the exec queue, since an entry can sit there for hours across retries and the reorg can land at any point in that window. Entries loaded from a file written before this are grandfathered rather than voided on a missing field. - Stop spending the retry budget on maturity. SelectCoins failing for want of spendable coin is not an error, but it consumed one of 1440 retries every 60s, so a payment the pool fully intended to honour would hit GIVING UP 24h later and the miner would silently never be paid. Those attempts now defer without incrementing retries, logged hourly rather than every minute. GIVING UP now means what it says: 1440 real failures against a block still on-chain with the money available. - Schedule at COINBASE_SPENDABLE_DEPTH instead of COINBASE_MATURITY. At depth 100 a block's own coinbase is 20 blocks short of spendable, so its payout had to come from unrelated mature coin and the pool carried a permanent ~19-block float. The "96% of 934 payments went through at depth 100" note that justified the shorter wait was measured while this node was alone on a private fork paying itself. The extra 20 blocks also put the maturity gate past the reorg that caused all of the above.

Probed all twelve from two independent networks (a residential line and the pool's VPS) over v4 and v6, with DNS confirmed against 1.1.1.1: relay.current.fyi, relay.nostr.bg -- NXDOMAIN, no A and no AAAA. The domains are gone. (A getaddrinfo call on the VPS reports an address for them, but that is the VPS's own IPv6 handed back by its local resolver, not a real host.) relay.nostr.band, nostr.fmt.wiz.biz -- DNS resolves and TCP connects, but the TLS handshake never completes, from either network. Whether they are down or refusing non-browser clients, this node cannot use them. The remaining eight all complete a WebSocket upgrade. A dead relay is not free: each holds a connect/retry slot and delays discovery for no added redundancy.

Any restart in that window lost those payments with no record that anyone was owed anything. It was not hypothetical: a container restart on 2026-07-30 silently dropped a backlog of ~1,156 BTF, and there was nothing left to reconstruct it from. Re-queueing blindly would have double-paid whoever had already been sent to, so the payment needs to be idempotent rather than merely persistent. In-flight work is now a persisted list of per-payment records (paying_payouts.json), one per (block, address) -- the granularity SendMoney works at, and therefore the granularity at which a payment can be half-done when the process dies. Records are written, via a temp file and rename so a crash cannot truncate them, *before* the ledger entry is erased, so the debt is always described by at least one of the two files. Each attempt updates the record (retries, deferrals, backoff); settling it removes the record and rewrites the file, which is what stops a restart from paying twice. On startup ReconcilePayouts runs before the payout thread: - a record whose payment the wallet already shows -- matched on the payout comment plus the exact amount and destination -- is dropped, not resent. SendMoney commits the transaction to the wallet before it returns, so a crash immediately after sending is recoverable. - a ledger entry that has already been exploded into records is dropped, which is the crash-in-the-window case where both files describe one debt. The wallet check is deliberately biased towards "already paid": skipping a payment is visible in the log and recoverable, paying twice is neither. Verified live: sampling paying_payouts.json during a payout burst caught 3 records / 18.56 BTF mid-flight, cleared once paid, and the paid lines now carry the txid.

That cannot distinguish "we are not synced" from "the network is slow", and it failed in both directions on the same day. A pool mining its own fork keeps its tip fresh, so the check passed for the whole of heights 3966-4085 -- 120 consecutive blocks, all orphaned, 5890.50 BTF of payouts voided, and nothing in the log to say so.

It is a strict improvement and it is still blind in the one case that matters most. When the node goes deaf -- peers still in vNodes, nothing arriving -- no peer announces anything, GetPeerMedianHeight() returns -1, and the fallback mines our best chain. That fallback is right for a node that has not been told yet and wrong for a node that has stopped being able to hear, and a height nobody sent cannot tell those apart. A wedged node is exactly a node with no peer height information, so the gate was silent for the whole of heights 3966-4085: 120 blocks, 5890.50 BTF voided. Time can tell them apart. GetPeerHeightAgeSecs() measures how long since any peer reported a height, counting from first use rather than the epoch so a starting node does not refuse jobs before its first handshake. Past 20 minutes the pool stops issuing jobs and says so unconditionally in the log. /poolmineblind overrides it: without an escape hatch a genuinely isolated pool that is 90% of the hashrate could never restart its own chain, which is the deadlock the tip-age check used to cause. Also stop nStartingHeight from going stale. It was a snapshot taken once during the version handshake and never touched again, so on a long-lived connection the median is built from heights the peers had hours ago, and the behind-the-network check drifts toward 'everyone is behind us' and quietly stops firing. A peer that hands us a block is demonstrably at least at that block's height.

CNode::Disconnect() closed hSocket and left the member holding the stale number. ~CNode's only guard is 'hSocket != INVALID_SOCKET' and nothing in the tree ever assigned that sentinel, so the destructor closed the same number a second time. The two closes are five minutes apart by design: ThreadSocketHandler2 disconnects a node, sets nReleaseTime to GetTime() + 5*60, and parks it in vNodesDisconnected; GetRefCount() reports it busy until that expires, so 'delete pnode' -- and the second close -- cannot run before then. Linux hands out the lowest free descriptor. Measured on the pool: 202 open descriptors with a high-water mark of 216, so a freed number is reissued within seconds -- to a Nostr relay TLS socket, a rendezvous socket, a tunnel end, or a miner connection. Five minutes later the destructor closes it. The victim gets no error and no log line. It simply stops. That is the whole signature, including the part that never made sense: .btf block delivery and Nostr descriptor lookup share no lock, no queue and no thread, so they should not fail together. They share the file descriptor table, and a stray close is drawn from all of it. It also explains why #78 did not help and may have hurt. #78 drops stuck nodes -- it fired 41 times in one window -- and every drop is another Disconnect(), which is another delayed close armed against an innocent socket. Second bug, same symptom, different subsystem: the pooled relay sockets. ResolveDescriptor returned the instant a descriptor verified, leaving the relay's EOSE unread on a socket that goes straight back into g_relayPool, so the next caller read our leftovers as its own answer -- permanently one message out of step, and no code path anywhere inspected the subscription id that would have caught it. Worse, BtfResolve set lease.fOk = true on every failure path including a dead RecvText, labelling it 'exchange completed, just no match'. fOk = false is the only thing that ever closes a pooled socket or clears fConnected, so a relay connection that died was pinned in the pool, reported healthy, and reused for the life of the process. That is 'no Nostr descriptor found' for a descriptor that nak can see, cleared only by a restart. Now: read to EOSE before returning, match the subscription id, and keep a pooled socket only when the relay actually finished the conversation.

ProcessMessages reads a header, finds the body has not all arrived, pushes the header back onto the front of vRecv and breaks. Correct for a message still in flight. For one that never completes it is permanent: every later pass re-reads the same header and breaks in the same place, so that peer is never parsed again for the life of the process -- no blocks, no inv, not even its version message. Nothing rescues it: - a header may claim up to 256 MB (0x10000000) and still pass CMessageHeader::IsValid(), so a garbage or truncated header is accepted and then waited on forever; - nLastRecv is refreshed by any byte that arrives (net.cpp), whether or not it parses, so the inactivity timeout that drops a silent peer never fires on a peer that is merely unreadable; - the socket stays ESTABLISHED and select() keeps offering it, so nothing at the socket layer notices either. It also explains the signature that made no sense. A peer stuck before its version message is parsed keeps nStartingHeight == -1, so a node with a full vNodes still reports GetPeerMedianHeight() == -1 -- which is exactly what was observed, and exactly what disabled the pool's behind-the-network gate and let it fork. Evidence, from two wedges captured on the pool by the watchdog: MESSAGE-BREAK 2 ran 2014 times in the deaf window against 607 in the healthy window before it, while blocks received went to zero and the node kept processing miner traffic normally throughout. Now: a peer that announces a body and does not deliver it within two minutes is dropped, and says so in the log unconditionally. Two minutes is far beyond any legitimate header-to-body gap and well inside BTF_RECV_TIMEOUT_SECS.

It is a different proximate fault from the second one, and this is the part that turns a single bad socket into a node-wide outage. A failed select() zeroes both descriptor sets, so no peer is serviced on that pass. That is correct as far as it goes. What was missing is that nothing stopped the offending descriptor coming straight back: - the invalid socket was only marked fDisconnect, and a node is not removed from vNodes until it has drained or DISCONNECT_DRAIN_SECS has elapsed -- and it cannot drain, because its socket is gone; - the select set was rebuilt from vNodes with no check, so the same dead descriptor went back in on the very next pass and failed select() again. Measured in the capture: 1,027 consecutive 'its socket is no longer valid' passes across 61 seconds -- the full drain timeout -- one bad socket, and for the whole of it the node read nothing from anybody. The peer that caused it had 57 bytes unsent, so it took the slow path out. Now the descriptor is forgotten as soon as getsockopt says it is not ours: select() succeeds again on the next pass and every other peer is served normally while the dead node ages out as before. Deliberately forgotten rather than closed. getsockopt has just said this descriptor is no longer ours; calling close() on it is precisely how an unrelated socket gets closed instead, which is the fault fixed in e742d0b.

MAX_BLOCK_SIZE did not exist in this tree at all: Bitcoin's 1 MB cap arrived in 0.3.x, after the 0.1.0 this fork came from. A miner could produce a 32 MB block and every node would download, verify and store it. Upstream #111 (from #110 by mtg0001). The cap is a tightening, so a node that does not upgrade is the permissive one. Measured upstream over 5709 blocks: largest 34,290 bytes, median 216, so 1 MB rejects nothing that exists. Upstream shipped the validation half only. Both places that ASSEMBLE a block still filled to MAX_SIZE/2 (16 MB), which was consistent against a 32 MB validation cap and is inverted by a 1 MB one -- the node would solve a block and then reject it itself. Fixed both: main.cpp CreateNewBlock, the node's own miner rpc.cpp RebuildJob, the POOL's job builder -- the one that matters here, because every miner on the pool would be working a template the network rejects, and this pool is ~90% of hashrate Half the cap in both, preserving the original margin: each test runs against a transaction that is already counted, so the loop can overshoot by one.

The old path consumed the header, found the payload short, inserted the header back at the front of vRecv, then Sleep(100) inside the shared message thread. A peer that announces a large payload and drips bytes made every pass pay an O(n) insert and a 100 ms stall -- one peer slowing the thread that serves all of them. Now the header is read from a copy and only skipped once the whole body has arrived, so there is nothing to put back and nothing to sleep for. Kept OURS, not upstream's, on the timeout: upstream restarts its clock only when the (size, command) pair changes, which drops a peer sending one big message slowly but honestly. This times the STALL -- the clock restarts on any progress -- which is the distinction that matters on a slow link. Also from #109: a header could announce 256 MB while serialize.h refuses anything over MAX_SIZE (32 MB), so the check admitted an allocation the parser would reject anyway and burned a peer slot for two minutes doing it. MAX_PROTOCOL_MESSAGE_SIZE ties the two together. 8x less a peer can make us hold, and this node takes public Stratum. And #103's other half: ~CNode closed its socket with a raw closesocket(), invisible to the accounting, and left hSocket set afterwards -- which is how a descriptor number that now belongs to somebody else gets closed a second time.

Inside a container that is the wrong number: with --cpuset-cpus 0-5 on a 12-core host it still answers 12, and every caller that sized a pool from it oversubscribed 2x. Measured on the pool box: - the pool node logged "Mining with 11 thread(s) of 12 core(s)" while confined to 6 CPUs - a burst miner launched with /hashthreads=2 filled the ~2 GB RandomX dataset with 12 threads, alongside the pool node in the same 8 GB container AvailableCoreCount() asks sched_getaffinity what the cpuset actually permits, which is the number all of these meant. It cannot make the dataset build slower: the CPU budget is identical either way, so fewer threads on the same cores is the same work without the thrash. Falls back to hardware_concurrency where the call is unavailable, and never returns 0 because callers subtract from it. Not the cause of the burst miner dying -- that was a corrupt Berkeley DB environment in the worker datadir -- but it is why the failure landed on the dataset build, and it is wrong on its own terms.

None of them had a caller left anywhere in the tree, so all four were reachable only from the outside. checkorder called GenerateNewKey() -- AddKey(), a wallet.dat write -- for any peer that asked, and handed back the pubkey. Its comment claims the cache keeps one key per ip, and on a 2009 network of routable addresses it did. Not here: inbound peers arrive through a rendezvous tunnel and are tagged by BtfMarkerAddr() over three random bytes, so addr.ip is fresh every connection and the cache never hits. Reconnect in a loop and the node mints a key per connection, none of them in any backup taken beforehand, which for a pre-BIP32 wallet is how coins go missing. The map holding them was static and never trimmed. submitorder AddToWallet()'d a CWalletTx from any peer that sent one. It had to be a valid transaction; it did not have to be ours. review checked a signature the sender made with its own key, which proves possession and authorises nothing, then appended to reviews.dat by reading the whole vector, pushing one entry and writing it all back -- quadratic disk on an unbounded map off the socket -- then walked a link graph the same peer supplied and relayed the message to every other node. reply dispatched into CRequestTracker. Nothing ever called PushRequest, so the table was permanently empty and the handler was a parser and nothing else. Removed with the subsystem behind them: market.cpp, CProduct, CReview, CUser, CReviewDB, the advert publish templates and the subscribe channel machinery, none of which had an inbound handler either. MSG_REVIEW, MSG_PRODUCT and MSG_TABLE stay in the inv enum, unserved: CInv puts type on the wire as an integer and MSG_TX and MSG_BLOCK are shared with every other node. Unknown commands are already ignored for extensibility, so peers still running these lose nothing but an answer they never asked for. Verified by a clean build of bitflash-node.

The two counts multiplied instead of dividing. Measured on the pool box with /hashthreads=2: a container with no cpuset logged "Mining with 11 thread(s) of 12 core(s)" -- 11 sessions, 22 hash threads on 12 cores, 1058% CPU, load 22.68 -- while the same binary under --cpuset-cpus 10,11 logged one session and 199%. The second miner (8 cores, /hashthreads=1) ran 7 sessions and went 74C to 89C. No code differed between those runs. Only the cpuset did, which means the cpuset was holding the thread count down by accident and every deployment without one was oversubscribed. Participant mode now starts exactly one session, so /hashthreads means what it says instead of being multiplied by the core count. The worker count moves to ParticipantHashThreadCount(), next to MinerThreadCount() where the two are easy to confuse, so what is printed at startup and what actually hashes cannot drift apart -- and it IS printed now. It was only ever visible under -debug, which is how eleven sessions ran unnoticed. Same host, same cpuset (0-3), same arguments, measured as a delta over 20 s more than four minutes after start: before 399% CPU, 6-7 threads hot, 3 sessions after 201% CPU, exactly 2 threads at 99.9%, 1 session Solo mining is untouched: /gen without /participant still starts MinerThreadCount() threads.

The guard restarts the clock only when nMsgWaitSince is 0 or the buffer has grown since the last look. Garbage in nMsgWaitSince is neither, so the very first look fell through to the timeout branch. A peer that merely split a message across two TCP segments -- header in one, body in the next, which is ordinary on any real link -- could be dropped as unreadable on first contact, before it had sent anything wrong and often before its version message. It was never reproducible either: what happened depended on what had last used that heap. The log reported the stall as roughly the age of the epoch: peer 127.0.0.1:8433 announced a 100 byte 'block' and has sent nothing more for 1786593923 s (0 of 100 payload bytes) -- dropping, this peer is unreadable Every node is running this. Introduced in 7f6e5ad, which added the pair to the class and to ProcessMessages but not to the constructor; the constructor went on initialising nIncompleteMessageStart, nIncompleteMessageSize and strIncompleteMessageCommand, the upstream members our implementation supersedes. 5490d66 removed their last reader from ProcessMessages, and nothing has read or written them since, so they go, with BTF_INCOMPLETE_MESSAGE_TIMEOUT_SECS -- decoy state in a networking struct is how this happened, and the merge ahead of us would carry it further. The initialiser list now follows declaration order, so a member missing from it is visible. The net-message selftest was asserting on those dead members too, which is why it could not have caught this: it read state no code path writes, and its stale-message case passed only when the garbage in nMsgWaitSince happened to look old. Rewired onto nMsgWaitSince / nMsgWaitSize / BTF_MSG_WAIT_MAX_SECS, and given the two cases it never covered -- a new peer's clock must start stopped, and a peer that is still delivering payload must not be dropped however old its clock is. Measured on the build host, 20 runs each: before, net-message failed 20/20 ("a fresh incomplete message does not disconnect immediately" failed 17/20 by itself). After, 20/20 pass. Rewired selftest against a reverted constructor fix: fails 20/20, deterministically, where the old suite caught it by luck or not at all. --- src/net.h | 16 +++++++--------- src/selftest.cpp | 37 +++++++++++++++++++++++++++++++------ 2 files changed, 38 insertions(+), 15 deletions(-) (limited to 'src') diff --git a/src/net.h b/src/net.h index 8b0245a..3c8c409 100644 --- a/src/net.h +++ b/src/net.h @@ -89,10 +89,9 @@ static const int BTF_HANDSHAKE_GRACE_SECS = 60; // A serialized object cannot be larger than MAX_SIZE, so no valid network // message needs the old 256 MB header allowance.

The event loop wrote pending_payouts.json from QueuePayouts and the orphan-void path with the ledger mutex HELD; the payout thread wrote it from RecordPayoutTxid and ForfeitPayoutRecipient with the mutex RELEASED. Both fopen()ed the same ".tmp" with independent handles and both rename()d it. Two ways that ends, both live money: - the renamed file is a mixture of two images. LoadPendingPayouts throws inside its parse loop, logs one warning, and the node comes up with a nearly empty ledger -- every obligation not yet exploded into an in-flight record is simply gone, with nothing on disk saying anyone was owed it. - a lost update: the payout thread's older snapshot lands after the event loop's newer one and silently erases a whole round that had just been queued. Neither parent had this. Upstream writes under the mutex everywhere; the pre-merge tree had one writer thread and no ledger mutex. The merge invented the window while fixing a real problem -- the event loop should not block in FlushMaturePayouts behind a per-recipient fsync on the payout thread -- so putting the write back under the ledger mutex is not the fix. Instead: a per-file write mutex that is never held together with a data mutex, plus a version on every snapshot. - serialising happens under the data mutex and stamps a monotonically increasing sequence number (gPayoutLedgerSeq). - publishing happens with the data mutex released, under the file mutex, and drops any blob whose sequence number is not strictly newer than the one already on disk. Because each blob is a whole-state dump of a single in-memory structure and the sequence number is assigned under the mutex guarding that structure, a higher sequence number is by construction a later state -- so discarding an older blob loses nothing, and the file can only move forwards. Writers may queue and complete in any order and the published file is still the newest state anyone has serialised. A failed write deliberately does not advance the published sequence, so the next write still tries. The same treatment is applied to paying_payouts.json and pool_rounds.json. Neither had the interleaving race -- gPayoutExecMutex and gPoolRoundsMutex already serialise their writers -- but both did their I/O under a mutex the event loop takes (FlushMaturePayouts, RecordPoolRound), so both were a place for the event loop to wait on the payout thread's disk. They are now written outside those mutexes on the same versioned terms, which is also what makes adding fsync to these paths safe. pool_status.json keeps a plain atomic write with no version guard: RefreshStats is its only caller and only ever runs on the event loop, so it has a single writer by construction. It shares the same WriteFileAtomic helper so the durability rules live in one place. No on-disk format change. --- src/rpc.cpp | 431 ++++++++++++++++++++++++++++++++++++++---------------------- 1 file changed, 272 insertions(+), 159 deletions(-) (limited to 'src') diff --git a/src/rpc.cpp b/src/rpc.cpp index 8af2fbe..76867ab 100644 --- a/src/rpc.cpp +++ b/src/rpc.cpp @@ -360,6 +360,12 @@ struct PendingPayout { }; static std::vector gPendingPayouts; static std::mutex gPayoutLedgerMutex; +// Bumped on every serialisation, under gPayoutLedgerMutex.

Entries restored from a file written before payouts were keyed by hash all carry hash 0. Two of them therefore compare equal, and the first one found answers for the second: - RecordPayoutTxid writes a txid against the wrong round. That round can then satisfy PayoutFullyPaid and be erased from the ledger while the debt it recorded is still owed, and nothing on disk remembers it. - ReconcilePayouts drops a live in-flight record on startup because a different zero-hash round had already paid that same address. SamePayoutRound() decides it properly: a non-zero hash is unique and settles the question on its own, a zero hash falls back to the block height (which LoadPendingPayouts supplies for any entry able to name its own maturity), and a zero hash never matches a real one. Refusing to match is the safe direction at all six sites, because each treats a match as "this debt is already handled". The orphan-void scan is deliberately left alone: PayoutBlockStillOnChain returns true for a zero hash, so a grandfathered entry can never enter the orphaned list and there is nothing there to cross-match. For the residual case where an entry has neither hash nor height -- which no file this tree has written can produce -- FlushMaturePayouts now refuses to explode it and logs why, rather than paying against an identity that could belong to another round. Not paying is recoverable; recording a payment against the wrong debt is not. PayoutIdForBlock's grandfathered "block-" fallback is unchanged and still safe: that id is only ever matched against pool_payout_id, which no pre-upgrade transaction carries.

ReconcilePayouts restored gPaying from disk but left that set empty, and FlushMaturePayouts deduped only against it and against the ledger's paidTxids -- never against gPaying itself. So a round that had been exploded but not yet paid got a SECOND PayingRecord for every unpaid recipient on the first flush after every restart. Another restart added a third. The crash test saw exactly that: two byte-identical records for one (block, address). ForgetPayment and ReschedulePayment then found their record with SamePayment(), a field-by-field comparison, which stops being an identity the moment two records are equal. Every update landed in the first slot and the second was never touched: - the duplicate's retryAfter stayed 0, so it ran in every 500 ms batch instead of once a minute; - each pass wrote retries = 0+1 into the FIRST slot, resetting its count, so the 1440-retry budget never completed and forfeit was unreachable; - the duplicate's fProbeWallet was never cleared, so FindRecordedPoolPayout -- a full mapWallet scan under cs_mapWallet -- ran twice a second per stuck recipient, forever, along with GetBalance() and, whenever funds allowed, SendMoney/CreateTransaction under cs_main. That is a permanent hot loop holding cs_mapWallet and cs_main on a pool node, starving RebuildJob() so job refresh and block submission stall. It is reached by the ordinary state of a payment waiting for coin or for an unlocked wallet. It did not double-pay only because a slot can reach SendMoney unprobed only when fProbeWallet is already false, and any successful payment calls ForgetPayment, which erases exactly the one slot that could be in that state. That invariant is emergent, undocumented, and dies the moment anyone erases by index or gives the record a stable identity -- which is precisely what this commit does, so it is replaced by a structural one. Both halves are fixed. Not creating duplicates: - ReconcilePayouts rebuilds gQueuedPayouts from the restored gPaying, so the first flush after a restart no longer re-explodes rounds already in flight; - FlushMaturePayouts additionally refuses to append a record for a (round, address) that gPaying already holds. That check is the invariant proper -- the round-level set is an optimisation that can be stale, gPaying is the list being protected; - LoadPaying collapses duplicates already on disk as it reads them, merging the retry and deferral counts upwards, so a file written by the broken build does not inherit the pathology into the fixed one. Real identity: PayingRecord gains an id, assigned under gPayoutExecMutex, and ForgetPayment/ReschedulePayment match on it instead of on values. SamePayment is deleted. The id is process-local and deliberately not persisted -- gPaying is rebuilt from disk at every start, so it only has to name a slot within one run, and reading ids back would mean trusting a file to contain no duplicates. The exactly-once property is now the conjunction of four checks that each hold on their own, rather than one accident: 1. at most one gPaying record per (round, address), enforced at insert; 2. the ledger's paidTxids, re-checked at the top of every attempt; 3. the wallet probe, once per record, before its first send; 4. state updates addressed by record id, so no slot can be skipped. No on-disk format change: the id is not written, and duplicate records in an existing file are read and collapsed. --- src/rpc.cpp | 118 +++++++++++++++++++++++++++++++++++++++++++++++++----------- 1 file changed, 97 insertions(+), 21 deletions(-) (limited to 'src') diff --git a/src/rpc.cpp b/src/rpc.cpp index b6b26f1..7badb7c 100644 --- a/src/rpc.cpp +++ b/src/rpc.cpp @@ -680,6 +680,18 @@ static void LoadPendingPayouts() // and reconciling against the wallet on startup, is what makes a restart // survivable. struct PayingRecord { + // Identity of this SLOT, distinct from the identity of the payment it + // describes.

That metadata is written only by this build. Every payout the pool has actually sent, in the wallet right now, carries nothing but a "comment". So the first boot after this upgrade is the dangerous one: swap the binary after an unclean shutdown with payments in flight, and the recovery probe finds no evidence for any of them and pays every one of those recipients a second time. The deleted WalletAlreadyPaid() matched on what the payment WAS -- the comment plus an output paying exactly that amount to exactly that script -- and that evidence is still sitting in the wallet. It just stopped being read. The probe now answers with which kind of evidence it found, and the legacy form is restored as a fallback under three constraints that keep it from answering for a round that is not the one being asked about: 1. it is consulted only when the structured lookup found nothing, so the exact path stays primary and strictly better going forward; 2. any transaction carrying pool_payout_id is excluded from it outright. That key means this build wrote the transaction, and this build's transactions are adjudicated exactly -- so a newer round's payment can never be offered as proof for an older one. Only pre-upgrade transactions, which is the entire population the fallback exists for, are eligible; 3. a txid already credited to a DIFFERENT (round, address) is excluded -- from the ledger's paidTxids, which is durable across restarts, and from what this process has already claimed. One legacy transaction therefore settles at most one debt, so N transactions can never discharge more than N obligations. Two debts with one transaction pays the second, which is the correct reading of the evidence. What cannot be resolved from a comment alone is two PRE-UPGRADE rounds at the same height paying the same address the same amount, because the comment carries only the height. That requires a reorg, and the losing round's ledger entry is voided by the orphan check before it can be paid, so the two cannot both be live. Where the evidence genuinely runs out the fallback does not match and the payment is made: paying a debt that cannot be proven settled is the correct default for a pool, and it is the direction that does not keep a miner's money. Recovery on legacy evidence logs loudly and says exactly what it matched on, because it is a judgement made about a binary that is no longer running. The two lookups share one pass over mapWallet. The structured path used to scan alone; adding a second scan would have doubled a linear walk taken under cs_mapWallet, which the whole node contends on.

It was reachable from two entirely ordinary conditions. The deferral gate compared GetBalance() against r.amount, ignoring the fee. A balance anywhere between amount and amount+fee therefore passed the gate, failed inside SendMoney, and was counted as a send FAILURE -- a retry. At one a minute, 1440 of those is 24 hours, and then the recipient is gone. A wallet left locked overnight did exactly the same thing: every attempt fails because nothing can be signed, and each failure spent budget. Three changes. The gate now requires amount + nTransactionFee, which is the part of the fee knowable before the transaction exists. It deliberately does not try to reserve GetMinFee(), which depends on the serialised size and so on how many inputs SelectCoins happens to pick: refusing to attempt a payment the wallet could actually have made is its own way of not paying a miner. A locked wallet is now a deferral at the same gate, for the same reason maturity is. Failures are classified after the fact instead of all counting as faults. The balance and lock state are re-read after SendMoney returns -- it holds cs_main and can block for a long time, so both may have moved -- and if the wallet is locked, or the balance no longer covers amount + fee + one fee tier of headroom, the attempt is recorded as a deferral. That headroom is where the size-dependent part of the fee lands, so a fee shortfall is a wait rather than a fault, which is what it is. The retry budget therefore now only counts failures that happened while the payment was funded, the wallet was unlocked, and the funding block was on the main chain. Reaching 1440 of those means the wallet refuses a payment it has every means to make, which is the only state in which the payment can be called impossible rather than merely blocked. The give-up log says which conditions held, rather than implying it. Finally, the forfeit is reconciled with the public record. Dropping the amount from the ledger while pool_rounds.json goes on advertising the address as owed with "txid": null left the pool's two accounts of the same round permanently disagreeing, with the operator holding the difference. PoolRoundProof gains a per-address forfeited/forfeitReason, written by MarkPoolRoundForfeited when the ledger writes the debt off, and pool_status.json counts those separately from genuinely unpaid ones instead of reporting them as still pending. On-disk: pool_rounds.json gains optional "forfeited" and "forfeitReason" keys inside a payout object, and pool_status.json gains "forfeitedPayouts" per round. Both are emitted only when a forfeit has actually happened, both are read back with defaults, and files written by any earlier build load unchanged. --- src/rpc.cpp | 214 +++++++++++++++++++++++++++++++++++++++++++++++++----------- 1 file changed, 175 insertions(+), 39 deletions(-) (limited to 'src') diff --git a/src/rpc.cpp b/src/rpc.cpp index b71457c..6f6d101 100644 --- a/src/rpc.cpp +++ b/src/rpc.cpp @@ -386,6 +386,12 @@ struct PoolRoundProof { std::map shares; std::map payouts; std::map paidTxids; + // Recipients the ledger has written off, and why.

PendingPayout::retryAfter was declared, serialised into pending_payouts.json, loaded back, and tested at the flush gate -- and the only assignment to it anywhere in the tree was `= 0`. The gate could never fire. PendingPayout's `retries` and `deferrals` were the same: carried, never written. Dead fields next to live ones in a structure this one is easy to reach for by mistake, and a gate that looks like backoff but is not is worse than no gate at all. PayingRecord::retryAfter is the clock the payout thread actually uses -- and SavePayingLocked did not write it. Every restart therefore reset every backing-off payment to "ready now" and put the entire in-flight set into the very next 500 ms batch instead of once a minute. On a node restarting in a loop that is a continuous retry storm against a wallet that has already said no, each pass taking cs_main. The dead copy is deleted, along with the flush gate that read it and the one `retryAfter = 0` in RecordPayoutTxid. The live one is now persisted and restored. Retry state stays where the failure happens -- per (round, recipient), which is the granularity SendMoney works at. On disk, both directions still read: - pending_payouts.json no longer has "retryAfter" written into it, and no longer reads one. Files that carry it (everything the merged build wrote, always as 0) load unchanged, the key simply ignored. A build that expects it defaults an absent key to 0, which is the only value it has ever held. - paying_payouts.json gains "retryAfter".

That is atomic against the process dying -- which is what the crash test exercised -- and not against the machine dying. A power cut or a hard VM reset can land the rename on the platter ahead of the data it points at, and what comes back is a short or empty file. For pending_payouts.json that is not a corrupt ledger, it is an absent one: LoadPendingPayouts catches the parse error, logs one warning, and the node starts up owing nobody anything. Total silent loss of the unpaid ledger, from a clean-looking boot. WriteFileAtomic now fflush()es and fsync()s the temp file before renaming it, and fsync()s the containing directory afterwards so the new directory entry is durable as well. If the data cannot be made durable the rename does not happen at all: the previous file is still intact and still correct, and the next write will try again. Ordering the sync before the rename is the point -- publishing a name that points at nothing is the exact failure being prevented. The directory sync is best effort; a filesystem that will not let the directory be opened for it is not a reason to refuse to write the ledger. This is only affordable because the preceding commit moved all three writes out from under gPayoutLedgerMutex / gPayoutExecMutex / gPoolRoundsMutex. An fsync under any of those would park the pool event loop on the payout thread's disk, which is the contention the merge was right to remove. Applies to upstream too and is being reported there.

It runs against a scratch data directory and an in-memory wallet map: it never opens wallet.dat, never touches a real datadir, and never sends anything. What it asserts, defect by defect: - a restart does not duplicate an in-flight record. A matured round is exploded, the process state is thrown away and reloaded from the files twice, and the in-flight list must still hold exactly one record per recipient. Both guards are checked separately -- once with the round-level set restored, and once with it deliberately emptied so only the per-recipient check against gPaying can save it. A paying file already containing the duplicate the old build wrote must collapse on load, with the attempt counts merged upwards rather than reset. - state updates address a slot, not a value. Two records equal in every field -- exactly what the old code produced -- and rescheduling or forgetting one must land on the one it was given. - the ledger file cannot be published from a stale snapshot. An older snapshot published after a newer one must not appear on disk, and four threads publishing 64 large images of the same file in different orders must leave it parseable and equal to the highest version, whatever order they finish in. - a payment with only a legacy comment is recognised as already paid, and the fallback's limits hold: it requires the right recipient, the exact amount and the right height; one legacy transaction cannot settle a second debt; a transaction carrying another round's structured metadata is never accepted as legacy evidence; and the structured match still wins where it applies. - grandfathered zero-hash rounds do not answer for each other, both as a direct test of the round comparison and end to end -- recording a txid against one zero-hash round must leave the other still owed. - the retry clock that is actually used survives a restart. - a forfeit is published rather than silently dropped: the ledger loses that recipient and only that recipient, and the round proof records it with a reason instead of going on advertising the address as owed. - on-disk compatibility, checked against the real shapes: the live production pending_payouts.json (amounts / blockHash / blockHeight / matureAtHeight and nothing else), the merged build's shape including the retryAfter this build no longer writes, and a round trip through this build. Each assertion was verified to fail when its defect is put back: seven mutations were applied one at a time to a scratch copy and every one was caught. Notably, re-introducing either half of the duplicate-record fix alone is caught by its own assertion while the other half still prevents the duplicate -- which is the defence in depth this series was asked for, checked rather than asserted. --- src/Makefile | 1 + src/rpc.cpp | 671 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ src/selftest.cpp | 5 +- 3 files changed, 676 insertions(+), 1 deletion(-) (limited to 'src') diff --git a/src/Makefile b/src/Makefile index 1166daf..89ba559 100644 --- a/src/Makefile +++ b/src/Makefile @@ -192,6 +192,7 @@ tests: test_bip32 bitflash-node ./bitflash-node -selftest=net-message ./bitflash-node -selftest=consensus-limits ./bitflash-node -selftest=pool-stratum + ./bitflash-node -selftest=payout-ledger ./bitflash-node -selftest=parse-money ./bitflash-node -selftest=socks5-proxy diff --git a/src/rpc.cpp b/src/rpc.cpp index 45130ff..cebc349 100644 --- a/src/rpc.cpp +++ b/src/rpc.cpp @@ -38,6 +38,7 @@ #include #include +#include #include #include #include @@ -2749,6 +2750,676 @@ static bool HandleLine(Miner* m, const std::string& rawLine, return true; } +// --------------------------------------------------------------------------- +// payout-ledger self-test +// +// Regression cover for the payout defects fixed in this series.

Since 86b39b9 that write ends in fsync() on the file and fsync() on its directory. So every ten seconds the event loop performed two synchronous disk flushes holding the mutex the payout thread must take to record that a miner has been paid, and the payout thread waited behind them. Measured here on ext4/LVM/SSD: 3.78 ms mean per publish. On the pool's shared virtual disk it is higher and it has no upper bound under load. That is worse than the code the merge replaced, which wrote the same file under the same locks but buffered and without fsync. It also made 33f2e8a's headline claim -- "no thread waits on I/O holding gPayoutLedgerMutex, gPayoutExecMutex or gPoolRoundsMutex" -- false on the commit that asserted it. Split the same way as the three ledgers: SerializePoolStatusLocked() returns the image, PublishPoolStatus() writes it, and RefreshStats calls the second one after leaving the scope that holds the first. The ledger lock is also scoped to the loop that actually needs it, which is the gPayoutViews rebuild; the serialiser never needed it, since those rows were already copied. No version guard is added and none is needed: RefreshStats is still the only caller of either half, it still runs only on the event loop, and it now calls them in sequence on that one thread, so pool_status.json still has a single writer by construction. The comment saying so has been rechecked against the new shape rather than carried over. The claim is now tested rather than asserted. The self-test points strPoolStatusFile at a path whose ".tmp" is a FIFO, so the publish parks in open(2) until the test chooses to read, and every mutex the write must not be holding is required to be acquirable while it is parked. Against the previous code that test cannot pass: the writer sits inside fopen() holding gStatsMutex and gPayoutLedgerMutex, and nothing releases them until the write is allowed to finish. Verified by reintroducing the defect -- two assertions fail, deterministically. Property: pool_status.json is serialised under the locks and written with all four released, so no payout mutex is ever held across I/O. --- src/rpc.cpp | 290 +++++++++++++++++++++++++++++++++++++++++++++++++----------- 1 file changed, 237 insertions(+), 53 deletions(-) (limited to 'src') diff --git a/src/rpc.cpp b/src/rpc.cpp index be265db..403cb14 100644 --- a/src/rpc.cpp +++ b/src/rpc.cpp @@ -451,9 +451,20 @@ static std::string PoolRoundsFilePath() // number; publishing happens with the data mutex released and refuses any // blob whose sequence number is not newer than what is already on disk.

The classifier read GetBalance() after the failure and asked whether it covered `amount + nTransactionFee + CENT`. Every term of that was wrong. nTransactionFee is 0 on this pool -- it is only ever assigned from the GUI preferences dialog, which a headless node does not have -- so the entire reserve was one CENT. The fee it is meant to reserve for is GetMinFee(fDiscount=true), which is a step function of the serialised size: 0 below 10,000 bytes and (1 + bytes/1000) * CENT at or above it. There is no required-fee value between 1 and 11 CENT, so a one-CENT reserve is never the right number -- below the step nothing needs reserving, at the step it is short by a factor of eleven. Worse, the trigger correlates with the failure. A pool wallet close to broke selects many small inputs BECAUSE it is close to broke, and about 56 signed P2PKH inputs is 10 KB, which a pool that has been paying out accumulates as change. So: balance of amount + 0.05, the pre-send gate passes, CreateTransaction builds a transaction over 10 KB, the fee becomes 0.11, SelectCoins(amount + 0.11) fails, SendMoney returns false -- and (amount + 0.05) < (amount + 0 + 0.01) is false, so "funded", so a fault. The condition is stable, so it recurred every 60 s until the budget ran out and ForfeitPayoutRecipient erased the miner's money. Three changes. The wallet now says what it did. CreateTransaction takes an optional WalletSendResult out-parameter and sets WALLET_SEND_INSUFFICIENT_FUNDS on the one return that means a funding shortfall -- SelectCoins failing to cover nValue plus whatever fee that pass is working with, which on the second and later passes is GetMinFee() of the transaction the first pass actually built. SendMoney gains a four-argument overload returning that plus the fee that was required. The three-argument SendMoney stays, as a separate declaration rather than a default argument, because gui.cpp declares it itself instead of including main.h; walletcmd.cpp and the GUI are unchanged. These are wallet functions, not consensus. ClassifyPayoutSendFailure() then classifies the answer rather than guessing: locked or short of coin defers, anything else is a fault. There is no reserve left to get wrong, and the size-dependent fee is accounted for exactly, because the wallet computed it. And the give-up branch is gone. 1440 failures is not a decidable state, it is a count of how long we have been asking, and this pool reached it by misclassifying a permanent funding shortfall. A payment that keeps failing now stays in flight, keeps its ledger entry, keeps being reported as owed in pool_status.json, and keeps retrying once a minute. A debt that is never written off cannot be written off wrongly. The remaining call to ForfeitPayoutRecipient is the one decidable case -- the ledger names a string that is not a valid address, so no transaction can pay it -- which previously only dropped the in-flight record and left the ledger and the round proof claiming the debt forever. Tested against a real wallet and the real CreateTransaction, not against injected values, because the honest question is whether a wallet holding many small coins reports the state this code assumes. 60 coins of 1 BTF, balance 60.00, amount 59.95: CreateTransaction returns false with WALLET_SEND_INSUFFICIENT_FUNDS and a required fee of 0.11 -- and since GetMinFee returns 0 below 10,000 bytes, a required fee of 11 CENT is itself the measurement that the transaction crossed the step. The same test asserts that the old reserve judged that state "funded", and that the same wallet pays a 3-input transaction with a required fee of 0.00, which is why no fixed reserve is right for both. Property: a send that failed because the wallet could not fund it is deferred, whatever the transaction's size, and no number of failures erases a debt. --- src/main.cpp | 47 ++++++- src/main.h | 45 +++++- src/rpc.cpp | 441 +++++++++++++++++++++++++++++++++++++++++++++++++---------- 3 files changed, 454 insertions(+), 79 deletions(-) (limited to 'src') diff --git a/src/main.cpp b/src/main.cpp index 252911b..7b3e555 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -4907,9 +4907,17 @@ bool SelectCoins(int64 nTargetValue, set& setCoinsRet) -bool CreateTransaction(CScript scriptPubKey, int64 nValue, CWalletTx& wtxNew, int64& nFeeRequiredRet) +// presultRet, when given, says WHY this returned false: the caller cannot work +// it out afterwards.

A pre-upgrade payout that never confirmed is evidence of NON-payment, and it was being read as payment: the recipient is dropped from the in-flight list, a txid is recorded against the ledger entry, and the debt retires having never been settled. The miner is not paid and nothing on disk says they were owed. That is not hypothetical here. This tree has had a 280-block reorg (see the note in FlushMaturePayouts). A payout invalidated by one is still sitting in mapWallet with its comment intact, and the first boot after this upgrade -- the boot where the binary is swapped after an unclean shutdown with payments in flight -- is precisely when the legacy probe runs against it. The structured branch is deliberately left alone. This process sent those transactions moments earlier, and a send that failed leaves nothing behind: SendMoney calls RollbackTransactionSpent, which calls EraseFromWallet. Depth there would only reject payments that really were made. The check cannot be done inside the wallet scan. GetDepthInMainChain() reads mapBlockIndex and pindexBest, which belong to cs_main, and cs_main is taken before cs_mapWallet everywhere else in this tree -- CreateTransaction, ConnectBlock -- so testing it under cs_mapWallet would invert the lock order in the payout thread. Comment matches are collected in the scan and adjudicated afterwards under cs_main then cs_mapWallet, in that order. That also fixes a second thing: the old code stopped at the first comment match, so one unconfirmed transaction could hide a confirmed one behind it. A rejection logs the txid, height, amount and depth, and says the recipient will be paid, because this is the one decision where being wrong is unrecoverable in the direction that costs a miner money. Property: a payment is only ever inferred from a pre-upgrade comment when the transaction carrying it is in the main chain. --- src/rpc.cpp | 164 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++---- 1 file changed, 155 insertions(+), 9 deletions(-) (limited to 'src') diff --git a/src/rpc.cpp b/src/rpc.cpp index 06de7f2..b0436ba 100644 --- a/src/rpc.cpp +++ b/src/rpc.cpp @@ -1339,7 +1339,16 @@ static PayoutProbeResult FindRecordedPoolPayout(const std::string& id, want << OP_DUP << OP_HASH160 << h160 << OP_EQUALVERIFY << OP_CHECKSIG; const std::string comment = PayoutComment(blockHeight); - std::string legacyTxid; + // Candidate legacy matches, adjudicated after cs_mapWallet is released. + // + // The depth check cannot happen inside the scan: GetDepthInMainChain() + // reads mapBlockIndex and pindexBest, which belong to cs_main, and cs_main + // is taken BEFORE cs_mapWallet everywhere else in this tree + // (CreateTransaction, ConnectBlock).

Both loaders then return normally, having logged one line under a debug category, and the node carries on as though that were the whole ledger. The first publish afterwards writes the partial state over the file. ReconcilePayouts publishes unconditionally during startup, so that is milliseconds later -- before an operator could see the warning, let alone act on it. The only durable record of what the pool owed is then gone, and it is gone in the direction that costs miners money: the entries that failed to parse are the ones that vanish. 86b39b9's own commit message names this failure mode and then fixes only the write side. On any parse exception the file is now renamed to .bad., the path is added to a refusal set, and PublishVersioned declines to write it for the rest of the process. A node that has lost its ledger now comes up visibly missing it rather than quietly appearing to owe nobody anything, and the bytes are still there to reconcile against. Restarting into the same fault does not consume the evidence, because the quarantine name carries the time. Logged with printf rather than LogPrint: an operator who has just lost a payout ledger has to be told at whatever settings they were already running, and the name the file was moved to is the only route back to the data.

Every serialiser stamps `++gSeq`, so it never produces 0, and 0 then loses the `seq <= publishedSeq` comparison because publishedSeq starts at 0. Both halves of that are incidental. A serialiser written as `seq = gSeq++` -- one character different, and the natural way to write it -- publishes seq 0 for its first snapshot, which would sail past the comparison on a fresh process and write an empty ledger over a real one. There is also a live path that produces an unstamped blob today: FlushMaturePayouts declares `VersionedBlob ledgerSnap` and only fills it if something was voided, then publishes unconditionally. It is harmless for exactly the reasons above, which is to say for no reason that is written down anywhere. One line, checked explicitly, so the guarantee does not depend on how a future serialiser spells its increment.

That check is PayoutBlockStillOnChain(), which returns true for a zero hash -- and every pre-upgrade entry has a zero hash, because they were written before payouts recorded one. So it is a no-op for exactly the population the fallback exists to serve. The stated reason for a safety property was not the reason. The property does hold, by a different mechanism. SamePayoutRound() treats two zero-hash entries at the same height as the same round, so the pair is indistinguishable to every consumer, not just to this one: FlushMaturePayouts explodes one and skips the other as already queued, PaymentInFlightLocked refuses a second record for that (round, address), and RecordPayoutTxid settles against the first match. The pair presents as one debt and can be paid at most once. The cost of that -- only one of a genuine same-height pair would ever be paid -- is now written down too, rather than left as an implication. Both halves are asserted rather than reasoned about: the self-test checks that the orphan check passes a zero hash, and that two identical zero-hash entries at one height produce exactly one in-flight record.

With the per-file write mutex removed from PublishVersioned, `make tests` still went green 2 runs out of 5, and the assertion named "four threads publishing the same file never leave it unparseable" fired 0 times out of 5. It was asserting something true for reasons unrelated to the code it was pointed at. Two causes. The images were 64 arrays of 200 entries, identical in structure and within bytes of each other in length, so an interleaving of any two of them was still a valid JSON array. There was nothing structural for a torn write to break. They now alternate between one entry and five thousand: a write landing on top of another leaves either a truncated array or a small image followed by the tail of a large one, and neither parses. Worse, almost nothing was being written. Each thread walked a permutation of the images and PublishVersioned drops any blob not newer than what is on disk, so only the record highs in each permutation ever reached the disk -- about ten writes in total across four threads, which is not enough contention to produce a race however the images are shaped. Every publish now stamps its sequence number from a shared counter at the moment it is made, so every publish is newer than the last one issued and every publish writes: 400 of them, half of them 600 KB. And the file is now watched while the writers run rather than inspected once after they stop. "The published file is never observed unparseable" is the real invariant -- rename(2) is atomic, so a reader can only ever see a completely written image -- and sampling it only at the end looks at the one moment a torn file is least likely to have survived. Measured on the build host, five runs with the file mutex removed: 5 detections out of 5, every one of them on the unparseable-file assertion, which is the assertion that used to fire never. Five runs with the mutex in place: 5 passes. The whole payout-ledger self-test takes 1.4 s.

That was true when it was written and is no longer: the payout-ledger self-test drives RefreshStats directly, to check that no payout mutex is held across the write. The conclusion still holds -- the test calls it from one thread at a time with the pool not running, so pool_status.json still has a single writer -- but the reason a reader would check is now stated, along with what would invalidate it. A claim in a comment that has quietly stopped being true is how 33f2e8a came to assert that no thread waits on I/O holding gPayoutLedgerMutex on the commit that made it do so.

MAX_POOL_MINERS caps the miner list at 1000, but that is a count, and a count does not bound descriptor values: a Miner is removed only on clean disconnect, so half-open sessions hold their fds while the OS keeps issuing higher ones. Refuse the connection instead, and refuse on the limit that actually applies. On POSIX that is the descriptor value against FD_SETSIZE. On Windows an fd_set is a counted array of SOCKET handles whose values are arbitrary -- often large from the first accept -- so comparing a handle against FD_SETSIZE there would reject nearly every miner; the bound is how many sockets are held. This is a behaviour change: a pool at the limit now turns miners away with a log line rather than corrupting memory quietly.

On a desktop that is a first run. On a headless node it is usually a fault -- the datadir is not mounted, or wallet.dat was caught mid-rename by a backup -- and the new default turns that fault into a silent loss of custody rather than a loud failure. The damage is not the empty wallet, it is the marker. Creating the wallet also writes /wallet-backend = sqlite, and every later start reads that marker first: putting the real wallet.dat back no longer does anything, because the node stays on the empty SQLite wallet it made. 1.2.19 had the same fail-open on a missing wallet, but it created a wallet.dat, and restoring the backup over it recovered the funds. That runbook stops working here. So refuse when the startup is headless and no wallet of either kind is present, and say which flag makes it deliberate: /createwallet to start a new one, or /walletbackend=bdb for the Berkeley DB path. A node that meant to create a wallet says so; a node that lost its datadir gets an error instead of a fresh identity and a re-paid ledger. Upstream keeps the old behaviour; this is a fork divergence, and the three findings that would gate enabling the SQLite backend at all -- the non-atomic backend marker, WriteHDMaster's connection-wide transaction, and the encrypt-swap crash window -- remain open against upstream. --- src/main_gui.cpp | 29 +++++++++++++++++++++++++++++ src/selftest.cpp | 26 +++++++++++++++++++++----- 2 files changed, 50 insertions(+), 5 deletions(-) (limited to 'src') diff --git a/src/main_gui.cpp b/src/main_gui.cpp index 2743429..25cde1c 100644 --- a/src/main_gui.cpp +++ b/src/main_gui.cpp @@ -196,6 +196,9 @@ static void PrintUsage() printf(" /walletsqlite=FILE (stage-load a SQLite wallet export, then exit)\n"); printf(" /walletbackend=sqlite (opt-in: run the node on /wallet.sqlite\n"); printf(" instead of wallet.dat; export one first)\n"); + printf(" /createwallet (headless only: permit creating a new wallet in a\n"); + printf(" datadir that has none -- otherwise refused, since\n"); + printf(" a missing wallet is usually a mount/backup fault)\n"); printf(" /rescan (walk the chain for coins this wallet owns\n"); printf(" but never recorded, then exit)\n"); printf("\n"); @@ -835,6 +838,32 @@ int main(int argc, char* argv[]) else { fUseSQLite = true; fCreateSQLite = true; } } + // A headless node whose datadir holds no wallet of either kind is + // far more often an operations fault -- datadir not mounted, or + // wallet.dat caught mid-rename by a backup -- than a first run. + // Creating one here is not the harmless default it looks like: + // success also writes the backend marker, and from then on + // restoring the real wallet.dat no longer takes effect, because the + // marker keeps the node on the empty wallet it just made.

The branch was reaching for a real hazard, though, so say the hazard directly instead of deleting the guard: diff1 is ~uint256(0) >> 12, a hair under 2^244, so the true share target stops fitting in a uint256 once difficulty reaches 2^-12 (1/4096), and the fixed-point divisor (uint64)(difficulty * 65536.0) truncates to zero -- a division by zero -- for any difficulty under 2^-16. Past the first threshold getuint256() would return the low 256 bits of an oversized quotient, a wrapped target that is arbitrarily HARDER than difficulty 1. Both thresholds sit far below VARDIFF_MIN (0.001), so nothing live comes near this; the guard exists for any caller that bypasses vardiff. At those difficulties every hash is meant to be a share, so return all-ones, the easiest representable target. Boundary verified numerically against the exact fixed-point algorithm: at difficulty exactly 1/4096 the quotient is 2^256 - 4096 (fits), one ulp below it overflows, and below 2^-16 the divisor is zero.

Nothing in that pipeline distinguishes a replay from a first submission: a duplicated valid share passes every check and lands in roundShareCount[address]++ a second time, and roundShareCount is the divisor the payout split uses, so replaying one valid share N times multiplies that address's cut of the round by N. Keep a per-connection set of credited nonces on the Miner, reject a repeat with a "Duplicate share" stratum error before the rebuild and hash it would waste, and record the nonce at the moment the share is credited. The set is keyed to the job id the miner is currently working and cleared inside SendJob -- the single funnel every new-job path (initial authorize, block found, new block, 60s refresh, no-job watchdog, vardiff retargets) goes through -- so legitimate resubmissions across jobs are never refused. The clear is keyed on the id rather than unconditional because the vardiff retarget and stall watchdog re-send the CURRENT job, and an unconditional clear there would reopen the very replay window this closes. Job ids come from a monotonic atomic counter in RebuildJob, so an id is never recycled within a process.

The announced pool hashrate ran several times over ground truth because miners that had gone quiet were still contributing their last sample. Decay on time in the event loop's miner sweep. Per miner, compute the expected share interval -- ExpectedHashesForDifficulty(m->difficulty) divided by its current rate estimate -- and give it a grace of four such intervals with no share (at the vardiff target of one share per 15s that is about a minute of silence). Past the grace, decay the estimate with a half-life of one more expected interval, computed from absolute time so the curve does not depend on the loop's tick rate. The interval is clamped to [1s, 1h] so a fast miner at the vardiff floor, whose expected interval is milliseconds, is not decayed for ordinary share-delivery jitter, and a very slow miner's grace cannot stretch past the point where its estimate means anything.

Half-open TCP sessions send no FIN and raise no error, so they lived forever -- on the live pool authorize outpaced disconnect 2:1, over half the table never submitted a share, and the leak grew toward MAX_POOL_MINERS, past which the accept path refuses real miners. Two changes. First, an idle reap in the event loop's miner sweep: any miner whose last activity is older than POOL_IDLE_TIMEOUT_SECS (600s) is closed and erased through exactly the bookkeeping the clean-disconnect path uses -- log, sock_close, erase via std::find, delete -- collected into a side vector first so the sweep's iteration stays valid. Shares an idle miner already earned stay in roundShareCount, just as they do when a miner cleanly disconnects mid-round. To give the reap something honest to measure, lastSeen is now stamped on every complete line received (authorize and valid shares already stamped it; a miner that only subscribes, or sends unrecognised methods, previously looked dead from birth), with connectTime standing in for a connection that never completed a line. Ten minutes is far beyond the 15s vardiff share target and the 45s stall watchdog, so no miner that is actually hashing comes close. Second, SO_KEEPALIVE on sockets accepted by the loopback stratum listener, so a half-open session eventually errors out of recv and lands in the reap path on its own. This is a backstop only: the default cadence before the first probe is hours on most stacks, so the idle timeout fires long before keepalive does. Miners arriving via a relay ride a loopback socket pair whose real transport is the rendezvous socket owned by the tunnel pump threads, which keepalive cannot reach across -- for those the idle reap is also what finally tears the tunnel down, since closing the app end unblocks the pumps.

Threads are spawned per peer connection, so the pressure that triggers this scales with peer count, which is attacker-influenced. Observed killing a healthy participant worker mid-mining. Every spawn site in the node build, and what a failure now does: - btftunnel.cpp: both tunnel pumps are guarded. The inbound pump starts first because it owns cleanup of the pump end and rendezvous socket; if the second spawn is refused, shutdown() wakes the first out of its read and it cleans up itself -- closing those descriptors from the failure path instead would race it onto reused descriptors. Both paths return INVALID_SOCKET, which every caller already treats as "this connection failed". - btfrv.cpp: the relay's accept loop drops the connection it cannot serve and stops accepting for a moment -- longer after consecutive failures, capped at 5s -- instead of dying at an arbitrary one. The per-pair second pump now runs on the handling thread itself, leaving exactly one spawn to guard and nothing running yet to race. - main.cpp: a participant that cannot spawn its hash workers stops the ones that did start, drops the pool connection, and returns to the reconnect loop, the same way an ordinary disconnect does. - randomx_pow.cpp: dataset init joins the workers it got, releases the dataset, and stays in light mode -- the same trade the allocation failure path above it already makes. - rpc.cpp, net.cpp: the remaining unchecked _beginthread calls (which report failure by value, they cannot throw) now say precisely what did not start. The pool's accept and payout threads failing silently left the pool running deaf -- nobody accepts, nobody gets paid, and nothing in the log says why. Left alone deliberately: the per-relay accept spawns (rpc.cpp) already check, log and retry on the next poll; startup-critical spawns in net.cpp keep failing hard; the selftest-only std::thread uses may abort a selftest run, which is acceptable where dying over one peer is not. Verified: full node rebuilds clean and links; pool-stratum selftest passes; a scratch harness under RLIMIT_NPROC=1 confirms _beginthread reports -1 and std::thread throws system_error, the premises of every path above. --- src/btfrv.cpp | 49 ++++++++++++++++++++++++++++++++++++++++++++++--- src/btftunnel.cpp | 52 ++++++++++++++++++++++++++++++++++++++++++++++++---- src/main.cpp | 30 +++++++++++++++++++++++++++--- src/net.cpp | 5 +++-- src/randomx_pow.cpp | 28 ++++++++++++++++++++++------ src/rpc.cpp | 15 +++++++++++---- 6 files changed, 157 insertions(+), 22 deletions(-) (limited to 'src') diff --git a/src/btfrv.cpp b/src/btfrv.cpp index 133eb89..8ab735c 100644 --- a/src/btfrv.cpp +++ b/src/btfrv.cpp @@ -40,6 +40,8 @@ typedef int SOCKET; #include #include #include +#include +#include namespace btf { @@ -209,8 +211,28 @@ static void HandleIncoming(SOCKET s) bool a = WriteN(svc, &ok, 1); bool b = WriteN(s, &ok, 1); if (!a || !b) { CLOSESOCK(svc); CLOSESOCK(s); return; } - std::thread(Forward, s, svc).detach(); - std::thread(Forward, svc, s).detach(); + // One thread pumps s -> svc; this thread pumps svc -> s.

Track every block getdata in mapBlockFetch, erase the entry when the body arrives, and let SendMessages re-issue a request that has gone unanswered for BLOCK_FETCH_RETRY_SECS to the next peer that has not had a turn this round, restarting the round once every connected peer has. Client peers are skipped -- they declared they cannot serve bodies. Tracking is capped at 8 in-flight blocks so initial download, where hundreds are legitimately outstanding to one peer, is not duplicated to everybody else, and an entry is dropped after 10 minutes so a hash that was announced and never existed cannot be chased forever.

The inner for walked all of mapTransactions with no test, so a single pass could append the entire mempool -- the overshoot was bounded by mempool size, not by one transaction as the comment claimed. The pool builder did test, but only after the push, which bounds the overshoot at one transaction. Nothing caps how big one transaction may be: neither CheckTransaction nor AcceptTransaction limits it, so the mempool will hold one of any size the wire allows and "one transaction" is worth up to MAX_SIZE. A lone 1.5 MB transaction offering a large fee is therefore enough to make every template unmineable, and the fee is never paid because the block never confirms. Both now ask before appending and skip what does not fit, so the overshoot is zero and an oversized transaction costs the template nothing rather than invalidating it. The budget moves to MAX_BLOCK_SIZE_GEN so the two assemblers cannot drift on it again -- drift is what produced this. The test is ordered before ConnectInputs on purpose: ConnectInputs credits nFees by reference on success, so declining a transaction after calling it would leave the coinbase claiming a fee the block does not collect. Assembly only.

A reorg voided 100 ledger entries totalling 4,950 BTF and the log carried one line, naming one block and 49.49 BTF. The other 99 were counted and never printed, and no "(N similar)" summary appeared either -- a summary was only ever flushed when that same call site fired again, and after the reorg it never did. The missing 4,950 BTF was found by counting entries in pending_payouts.json. Add LogPrintAlways(), which skips the collapse entirely, and move the four payout lines that report money to it: an obligation voided, an obligation dropped, a payment sent, a payment that failed. All four are bursty by nature -- one reorg voids every entry funded by the orphaned block, from a single source line -- which is precisely why one line must not stand in for all of them. Their volume is bounded by how much money moved, which is a number worth the lines. Also sweep expired windows for every call site rather than only the one currently logging, so a burst that stops is still summarised, and report the window's real elapsed time instead of a hardcoded 3s. --- src/rpc.cpp | 10 +++--- src/util.cpp | 99 ++++++++++++++++++++++++++++++++++++++++++++++++++++++------ src/util.h | 22 +++++++++++--- 3 files changed, 114 insertions(+), 17 deletions(-) (limited to 'src') diff --git a/src/rpc.cpp b/src/rpc.cpp index a4b53ca..2e8f4b8 100644 --- a/src/rpc.cpp +++ b/src/rpc.cpp @@ -1732,7 +1732,9 @@ static void FlushMaturePayouts() } int64 total = 0; for (auto& kv : it->amounts) total += kv.second; - LogPrint("payout", "[payout] block %d (%s) was orphaned -- voiding %zu" + // Always: one line per voided entry, never a collapsed summary. + // A reorg voids these in a burst from this one source line. + LogPrintAlways("payout", "[payout] block %d (%s) was orphaned -- voiding %zu" " payment(s) totalling %s\n", it->blockHeight, it->blockHash.ToString().substr(0, 14).c_str(), it->amounts.size(), FormatMoney(total).c_str()); @@ -2036,7 +2038,7 @@ static void PayoutThreadFn(void*) // funding block can land at any point in that window.

Nothing asked what the assemblers produce, which is why a miner able to overshoot the cap by an entire mempool sat here unnoticed through both the deployed and candidate builds. Adds the other half: a template built from a 3 MB mempool stays inside the budget and passes CheckSizeLimits(); a transaction too big for the budget is skipped while the ones that fit are still taken; sigop-heavy transactions stop selection at MAX_BLOCK_SIGOPS while the block is still small. Plus the rule's edges, including that sigops exactly on the limit fit -- CheckBlock() fails on `>`, so assembly must accept what validation accepts. The test drives BlockTemplateFits the way the assemblers drive it rather than calling them: BitcoinMiner needs a CTxDB, a wallet key and cs_main, and RebuildJob is static in rpc.cpp. What that proves is the shared rule and the property it exists to give, which is where the defect was -- the budget was right and the enforcement was not. Checked against the bug: with the fit test neutered, eight of these fail, including both templates that CheckBlock() would have rejected.

It does: BtfAllRelays() returns vBtfMeetingRelays alone when fBtfRelayPinned, and every relay-choosing site -- the pool's AcceptLoopFn, the node's ThreadBtfAccept, and the dial path -- draws from it. vBtfMeetingRelays has exactly one writer, the pin itself. A pinned pool therefore spawns one accept thread, at the pin, and no discovered relay is registered at. The registration the incident actually caught was not the pool's. The "registered at" line it quotes exists only in ThreadBtfAccept, and 90.156.222.107:8434 is not a stranger's relay -- it is the third hardcoded seed, one of the three ThreadBtfAccept picks between at random when no pin is in force. That relay is only reachable with the pin absent, so the binary that logged it did not have one; both the pin and the operator-mode skip that keeps a pool out of that thread landed two days before the observation. What was genuinely wrong is that none of this could be read off a log. The pool announced no successful registration at all, and retried failures at one flat line, so "is this pool registered where its descriptor says" had no answer. So: - Advertise the relay after registering at it, not before. The optimistic order published a meeting node we were not yet listed at, and a miner resolving the descriptor inside that window spent its dial on a relay holding no registration for us. ThreadBtfAccept has always ordered it this way; the pool had not. - Log the relay registration succeeds at, name the pin when one is in force, and name each discovered relay the pin excludes. - Escalate when a pinned relay keeps refusing: a pin has no fallback, so an unregistered pin means the pool is unreachable, and that now says so instead of scrolling past. - Refuse to advertise a non-pinned relay in BtfSetActiveRelay. No caller can reach it today, but the descriptor is the one thing a miner obeys, so the invariant is enforced at the sink rather than retrusted to every future caller. Does not touch the registration-consumption race: the pool still gives up its registration on each pairing and re-registers after wrap-and-push. Moving the advertise call inside that loop does not widen the window, it only stops the descriptor naming a relay we never reached. --- src/nostr.cpp | 25 ++++++++++++++++++++++++ src/nostr.h | 3 +++ src/rpc.cpp | 61 ++++++++++++++++++++++++++++++++++++++++++++++++++--------- 3 files changed, 80 insertions(+), 9 deletions(-) (limited to 'src') diff --git a/src/nostr.cpp b/src/nostr.cpp index e2d839c..0717e12 100644 --- a/src/nostr.cpp +++ b/src/nostr.cpp @@ -151,6 +151,19 @@ string BtfActiveRelay() void BtfSetActiveRelay(const string& relay) { + // With /rvrelay set, the descriptor must never name anything but the pin. + // No caller can reach here with another relay today -- both registration + // paths draw their list from BtfAllRelays(), which returns the pin alone -- + // but the descriptor is the one thing a miner obeys, so the invariant is + // enforced at the sink instead of being retrusted to every future caller. + if (fBtfRelayPinned && + find(vBtfMeetingRelays.begin(), vBtfMeetingRelays.end(), relay) == vBtfMeetingRelays.end()) + { + LogPrint("pool", "refusing to advertise meeting relay %s: /rvrelay pins %s\n", + relay.c_str(), + vBtfMeetingRelays.empty() ?

Each pass recomputed `expected` -- and so `grace` -- from the estimate it had just decayed. Every decay raised `expected`, which raised the grace that gates the next decay, so `grace` chased `silent` upward and the reported rate settled into a 1/t crawl instead of the half-life the commit's own comment documents: 291x too high at ten half-lives past the grace, and still announcing 0.4% of baseline four hours into a silence. #7 is about the pool over-reporting its hashrate, and this under-corrected it for hours. The far end was worse. Once `expected` reached HASHRATE_MAX_INTERVAL it could not rise any further, the feedback that had been gating each pass was gone, and the decay did begin to compound -- once a second, against the total elapsed silence, because lastShareTime does not advance while a miner is quiet and nothing recorded when the decay had last run. A miner four hours silent fell from 0.4% of its baseline to 1e-11 of it over the next hundred seconds, with nothing in the code or the announced number to explain the cliff. Neither behaviour is worth tuning, so drop the sweep. hashRate is read in exactly one place -- RefreshStats, building the per-worker rows and the total that the pool status and the nostr announcement publish -- and vardiff retargets from share timing alone and never reads it. So leave the stored value as the sample it always was and have RefreshStats ask MinerReportedHashRate() what to publish: a pure function of that sample and the absolute silence since the last share. With no stored decay state there is nothing for a tick rate, a missed pass or a repeated pass to perturb, and the answer is bit-identical from 1/60 Hz to 1000 Hz because nothing accumulates, not because the arithmetic was written carefully. It also keeps the fade out of the estimator: the EWMA on the share path still blends against the value it last computed rather than a faded copy of it, so a miner that resumes recovers exactly as it did before any of this, and there is no decay timestamp for a newly accepted or newly authorised connection to be caught holding unset. RefreshStats takes one GetTime() for the whole sweep, so the rows and the total they are summed into describe a single instant rather than a smear across it. The clamp is written !(expected > MIN) so a NaN lands on the floor instead of sailing through; a negative `silent` from a clock stepping backwards reports the sample unchanged rather than scaling it up; and past HASHRATE_DECAY_CUTOFF half-lives the answer is a flat zero rather than pow() walking down into the denormals. This also drops the std::max(m->hashRate, 1e-9) the old pass carried, which the `hashRate <= 0.0` guard immediately above it had already made dead. pool-stratum gains ten checks over the policy: the full estimate inside the grace, a thousand samples at one instant returning one value and leaving the estimate untouched, a few percent lost one second past the grace rather than the whole estimate, exactly half at one expected interval past it, zero after an hour of silence, no inflation from a backwards clock, zero for a miner that has no rate sample yet, and nothing non-finite anywhere across a long silence. --- src/rpc.cpp | 194 +++++++++++++++++++++++++++++++++++++++++++++++++----------- 1 file changed, 160 insertions(+), 34 deletions(-) (limited to 'src') diff --git a/src/rpc.cpp b/src/rpc.cpp index df7ca05..9d98a4d 100644 --- a/src/rpc.cpp +++ b/src/rpc.cpp @@ -2488,21 +2488,26 @@ static const double VARDIFF_STALL_CUT = 4.0; // divide difficulty by thi // that stops hashing keeps its last estimate forever and RefreshStats sums // it into the announced pool total for as long as the connection sits open // -- the published pool hashrate ran several times over ground truth -// because of exactly this.

That reasoning does not survive the fact that GetHash() covers the 80-byte header and nothing else. Any peer that saw X announced holds X's header. It can answer our getdata with that header and a transaction list of its own invention; the reply still hashes to X, so the entry was erased, and CheckBlock then rejected the body on hashMerkleRoot and stored nothing. AlreadyHave stayed false, the mapAskFor entry had already been consumed when the getdata went out, and nothing recreated the tracking -- so X was never requested from anybody again unless some peer happened to re-announce it. That is the #33 stall, reachable on demand for one message. The erase now sits inside the success branch, beside the mapAlreadyAskedFor erase it belongs with. ProcessBlock returns true in exactly two cases, block accepted and block parked as an orphan, and both store it where AlreadyHave will find it, so one erase covers both and neither needs different treatment. Of the false cases, the two already-have ones are cleared by the sweep's own AlreadyHave check on its next pass, and the rest are rejections that must keep the entry. A mismatched merkle root is also now grounds to drop the peer. Nothing honest produces it: peer traffic rides the .btf channel, which is XChaCha20-Poly1305, so a body that arrives at all arrived intact, and the mismatch is the peer's own construction. Checking it in the handler also rejects a forged body before CheckBlock spends a RandomX hash on it. The unconditional log line fires once per connection, because ProcessMessages keeps draining the receive buffer after fDisconnect is set and a peer that packs many forged bodies into one buffer must not get a line for each. --- src/main.cpp | 50 +++++++++++++++++++++++++++++++++++++++++++++----- 1 file changed, 45 insertions(+), 5 deletions(-) (limited to 'src') diff --git a/src/main.cpp b/src/main.cpp index d9fe713..8926d57 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -3293,16 +3293,56 @@ bool ProcessMessage(CNode* pfrom, string strCommand, CDataStream& vRecv) CInv inv(MSG_BLOCK, pblock->GetHash()); pfrom->AddInventoryKnown(inv); - // The body is here, so the fetch is over whatever validation says - // next -- unlike the mapAlreadyAskedFor erase below, which stays - // conditional on acceptance so a peer feeding us garbage does not - // cancel the scheduled retries for the real thing. - mapBlockFetch.erase(inv.hash); + // GetHash() covers the 80-byte header and nothing else, so the hash + // coming out right does not make this the block we asked for.

AlreadyHave only asks whether we already hold the block, and with no header there is no work to check. So one inv carrying eight hashes that never existed filled all eight slots, and because a full table refused new entries outright, no genuinely new block was tracked again until the give-up timer expired ten minutes later. One message per ten minutes from a single connection switched failover off for the whole node -- not eight wasted slots, an off-switch. A full table now evicts. Eviction on its own would just be the same attack in a new shape, so the victim is chosen by occupancy: a peer may only take a slot from a peer holding strictly more slots than itself, and otherwise recycles one of its own oldest. A peer that has filled the table is the heaviest holder by definition, so its own entries are the only ones it can displace; a peer announcing its first block holds nothing, so it always evicts from the heaviest. A genuine announcement is therefore never refused a slot, whatever an attacker holds or across however many connections it holds it. Entries carry the announcing peer for this, set once on creation -- the failover sweep asks other peers later and none of them chose to announce the hash, so none of them should be charged for it. The two timestamps also get member initialisers. The insertion path uses operator[] and tests nTimeFirstAsked == 0 to spot a fresh entry, which worked on value-initialisation alone, but only until somebody gave the struct a constructor -- and this commit gives it a member that wants one. --- src/main.cpp | 110 ++++++++++++++++++++++++++++++++++++++++++++++++++++------- 1 file changed, 97 insertions(+), 13 deletions(-) (limited to 'src') diff --git a/src/main.cpp b/src/main.cpp index 8926d57..9ab1f44 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -75,12 +75,24 @@ multimap mapOrphanBlocksByPrev; // Capped small on purpose.

Shortening it to 15s was right at the tip and wrong everywhere else, and the eight-entry cap that made the failover table safe for catch-up does not cover this at all -- it is a different mechanism. At two minutes a second announcer's queued request almost always fired after the block had arrived, so AlreadyHave dropped it. At fifteen seconds, with a peer working through a 500-deep queue and block N legitimately minutes away, the second announcer is asked at +15s, the third at +30s, and the bulk download arrives once per announcer -- up to eight times over, with nothing bounding it. So the fast spacing is now conditional on tracking the tip, measured off the age of our own best block. Not off a peer-reported height: nStartingHeight is optional in the version message and every node released so far sends the short form, so it is -1 for essentially every peer, and where it does get filled in later it comes from the height of a block that peer served us, which during catch-up tracks our own height and would answer "at the tip" for the entire download. Block timestamps are the one clock a peer cannot move, being bounded above by CheckBlock and below by AcceptBlock's median-time rule. Thirty block intervals is the threshold: far longer than any stall worth failing over from, far shorter than catching up. Failover at the tip does not rest on this in any case -- mapBlockFetch re-issues a stalled getdata to the next peer on its own 15s timer, and that is what actually answers #33. --- src/main.cpp | 23 +++++++++++++++++++++++ src/net.h | 30 +++++++++++++++++++++++++++--- 2 files changed, 50 insertions(+), 3 deletions(-) (limited to 'src') diff --git a/src/main.cpp b/src/main.cpp index 9ab1f44..be89416 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -101,6 +101,29 @@ static const int BLOCK_FETCH_TRACK_MAX = 8; // forever; a re-announcement recreates it. static const int BLOCK_FETCH_GIVEUP_SECS = 10 * 60; +// How stale our own best block may be before we stop calling this the tip. +// Blocks target two minutes, so this is thirty intervals: far longer than any +// stall worth failing over from -- the one in #33 ran sixteen minutes -- and +// far shorter than catching up, which starts hours or days back. +static const int BLOCK_FETCH_TIP_AGE_SECS = 60 * 60; + +// Whether this node is tracking the tip rather than still catching up. +// +// Measured off the age of our own best block, not off any height a peer told +// us. nStartingHeight is optional in the version message and every node +// released so far sends the short form, so it is -1 for essentially every +// peer; and where it is filled in later it is filled in from the height of a +// block that peer served us, which during catch-up tracks our own height and +// would report "at the tip" for the whole download.

Sustained, that was tens of lines a minute, each naming a peer, driven entirely from outside. Split it. The per-peer detail -- which block, how long, which peer is being tried next -- moves behind the net category, where the rest of the getdata logging already is. What stays unconditional is a count with no addresses in it, over a window no peer can shorten: the first failover after a quiet spell still prints immediately, because the change from "blocks arrive" to "blocks are announced and not served" is the event worth seeing, and everything after it is summarised once a minute.

Which of the two got there first decided whether that shutdown addressed a live descriptor or a number the kernel had already handed back out -- in which case it tears down an unrelated connection. The inbound pump wins that race whenever the rendezvous socket dies before the app socket, which is the ordinary shape of a relay restart or a far side hanging up. The failure path added in 0b566b4 has the same hole. Its catch shuts down rv to wake an inbound pump it assumes is parked in RvReadN. PumpIn does not park when the rendezvous connection is already dead: it returns on its first length read and its wrapper closes both descriptors. A refused pthread_create and a dead rv are not independent -- both are symptoms of a loaded process -- so that is the likely case, not the exotic one. Both descriptors now belong to a shared_ptr the two pumps hold for the whole of their bodies, so the close happens after the last pump has stopped touching them and no shutdown can precede it. appEnd is unchanged: the caller gets it on success, StartTunnel closes it on every failure path, no pump ever touches it. 0b566b4's message says of that catch that "closing those descriptors from the failure path instead would race it". True as far as it goes, but it reads as though what the code did instead was safe, and it was not -- the shutdown raced the same close. There was no ordering there to prefer, only a missing owner. Measured against the real code with the relay in a separate process, every close() and shutdown() traced and pthread_create refused on demand: normal teardown, 25 tunnels 29 shutdowns on a closed fd -> 0 refused outbound spawn, 25 25 shutdowns on a closed fd -> 0 Close counts are identical before and after (8 and 5 per tunnel, every one accounted for) and live descriptors return to their starting count, so the defect was only ever the ordering, never a leak or a double close. --- src/btftunnel.cpp | 85 ++++++++++++++++++++++++++++++++++++++++++++----------- 1 file changed, 68 insertions(+), 17 deletions(-) (limited to 'src') diff --git a/src/btftunnel.cpp b/src/btftunnel.cpp index 2b3f818..4acca1a 100644 --- a/src/btftunnel.cpp +++ b/src/btftunnel.cpp @@ -26,6 +26,8 @@ typedef int SOCKET; #include "sockcount.h" #include #include +#include +#include #include #include #include @@ -121,9 +123,44 @@ static void PumpIn(SOCKET pumpEnd, RvSocket rv, std::vector key) shutdown((SOCKET)rv, SD_BOTH); } +// The pump end and the rendezvous socket, owned jointly by whoever is still +// using them.

It did that on every mining.notify, unconditionally, before the LogPrint that consumes the answer -- and LogPrint's category gate and its 3-second dedup both run after the lookup has already happened. The dedup bounds the log line. It never bounded the work. That left an unbounded cs_main acquisition rate on the participant's socket-reading thread, driven by the remote pool. Block validation can hold cs_main for a long time, and this thread is the one that handles mining.set_difficulty and share-submission replies, so a pool sending rapid notifies could stall the responses a miner is paid for. Hashing was never at risk -- jobShared is published before the lookup -- but the reader is not free to block. Most notifies in a round are a new job on the same tip, so the answer is now cached and re-resolved only when it could come out differently: a prevhash we have not resolved, or one we could not resolve last time while the chain has since moved. A block's height is fixed once mapBlockIndex knows it, so a cached "known" cannot go stale; an unknown is re-checked whenever nBestHeight changes, which is what catches a pool we were behind once we have caught up. The worst case -- a different prevhash every notify -- degrades to exactly the old cost, never worse. Measured over a 10-tip round of 30 jobs each, 300 acquisitions become 10; over 1000 notifies on a single fork we do not have, 1000 become 1. The log line is unchanged and still prints in full for every job, cached or not: prevhash plus height-or-"unknown to our chain". Nothing #15 asked for is lost, and a fork we cannot resolve keeps saying so on every job. The lookup is also wrapped in LogAcceptsCategory("worker") so the work follows the gate deciding whether anyone reads it. That is a no-op today -- "worker" is default-on in LogCategoryDefaultOn() -- and is there so the coupling survives the category ever moving behind -debug. The caching, not the gate, is what removes the acquisitions. The cache is four locals in the session scope, not statics: participant mode runs exactly one such thread (StartMinerThreads forces nThreads to 1 for MINE_PARTICIPANT), and session scope additionally means a reconnect re-resolves rather than trusting an answer from before a possible change of pool. --- src/main.cpp | 67 +++++++++++++++++++++++++++++++++++++++++++++++++----------- 1 file changed, 55 insertions(+), 12 deletions(-) (limited to 'src') diff --git a/src/main.cpp b/src/main.cpp index 3de3db0..c2d059b 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -3912,6 +3912,14 @@ connected: std::string jobId; unsigned char header[80] = {}; uint256 target; + // Cached answer to "which block is this job built on", for the + // mining.notify handler below -- see the comment there.

It is a lightweight tag (7ab5a8c) cut 2026-07-30, on a lineage that upstream/main (e0be70e, 2026-08-20) does not contain and no remote branch carries -- 272 commits that are not ours, against 376 of ours that are not theirs, from a merge-base at 56df983. Merging that tag would have deleted 18 files from src/, selftest.{cpp,h} and the whole 14-test suite among them, so the content is ported file by file instead. Compact block relay is the piece worth having: a peer that advertises sendcmpct gets 48-bit keyed short IDs per transaction rather than the transaction bytes, and reconstructs the block from its own mempool. It is purely additive on the wire -- a peer that never sends sendcmpct keeps receiving full block messages, so no coordinated upgrade is needed. This commit is the primitives and their unit test only. Nothing calls BuildCompactBlock or TryReconstructBlock yet: the P2P message handlers (sendcmpct/cmpctblock/getblocktxn/blocktxn) live in 1.2.23's main.cpp and are deliberately left for a follow-up, so that no attacker-controlled bytes reach this code until that wiring is reviewed on its own. The files needed no API adaptation -- mapTransactions, BEGIN/END and IMPLEMENT_SERIALIZE are unchanged across the divergence, and it compiled clean first time. Upstream never wired test_compactblock.cpp into its own Makefile, so it had never been built there; it links standalone the way test_bip32 does, supplying its own mapTransactions and GetAppDir to keep main.cpp out of the link. TEST_LIBS is overridable for the same reason NODE_LIBS is: the pinned dep tree ships libsodium as a static archive only. All 17 checks in test_compactblock pass, all 14 selftests still pass, and the consensus constants are unchanged against e4f898c. --- .gitignore | 1 + src/Makefile | 24 +++++-- src/compactblock.cpp | 155 ++++++++++++++++++++++++++++++++++++++++++++++ src/compactblock.h | 113 +++++++++++++++++++++++++++++++++ src/test_compactblock.cpp | 133 +++++++++++++++++++++++++++++++++++++++ 5 files changed, 422 insertions(+), 4 deletions(-) create mode 100644 src/compactblock.cpp create mode 100644 src/compactblock.h create mode 100644 src/test_compactblock.cpp (limited to 'src') diff --git a/.gitignore b/.gitignore index b18859f..77b1660 100644 --- a/.gitignore +++ b/.gitignore @@ -8,6 +8,7 @@ bitflash-node src/bitflash-node src/obj-node/ src/test_bip32 +src/test_compactblock # Release artefacts (produced by 'make windows' / 'make linux') Bitflash-*-windows/ diff --git a/src/Makefile b/src/Makefile index b931007..888110f 100644 --- a/src/Makefile +++ b/src/Makefile @@ -55,7 +55,8 @@ LIBS = -L$(SECP_LIB) -lsecp256k1 \ HEADERS = headers_core.h headers.h util.h main.h serialize.h uint256.h \ key.h bignum.h script.h db.h base58.h net.h nostr.h \ randomx_pow.h btfaddr.h btfchan.h btfrv.h btftunnel.h \ - selftest.h walletcmd.h wallet_sqlite.h compat.h sockcount.h proxy.h tor.h font_roboto.h + selftest.h walletcmd.h wallet_sqlite.h compat.h sockcount.h proxy.h tor.h font_roboto.h \ + compactblock.h IMGUI_OBJS = obj/imgui.o obj/imgui_draw.o obj/imgui_tables.o \ obj/imgui_widgets.o obj/imgui_impl_glfw.o obj/imgui_impl_opengl3.o @@ -64,7 +65,7 @@ NODE_OBJS = obj/util.o obj/script.o obj/db.o obj/net.o obj/main.o \ obj/sha.o obj/nostr.o obj/randomx_pow.o \ obj/btfaddr.o obj/btfchan.o obj/btfrv.o obj/btftunnel.o obj/rpc.o \ obj/selftest.o obj/bip32.o obj/walletcmd.o obj/wallet_sqlite.o \ - obj/proxy.o obj/tor.o + obj/proxy.o obj/tor.o obj/compactblock.o GUI_OBJS = obj/gui.o obj/main_gui.o @@ -194,13 +195,28 @@ fuzz-script-smoke: fuzz-script ./fuzz-script -runs=128 ../work/fuzz-corpus/script clean: - rm -rf obj obj-node obj-fuzz bitflash bitflash-node fuzz-net-message fuzz-script test_bip32 + rm -rf obj obj-node obj-fuzz bitflash bitflash-node fuzz-net-message fuzz-script test_bip32 test_compactblock test_bip32: test_bip32.cpp bip32.cpp bip32.h bip39_english.h $(CXX) $(CXXFLAGS) -o $@ test_bip32.cpp bip32.cpp -lssl -lcrypto -tests: test_bip32 bitflash-node +# Upstream shipped test_compactblock.cpp with no build rule at all, so it was +# never compiled there.

Kept separate so the deviation from upstream's bytes is reviewable on its own. BuildCompactBlock ignored the RAND_bytes return value. On failure nonceBytes is left uninitialised and an indeterminate shortIdNonce is memcpy'd out and sent on the wire -- and that nonce is exactly what the file relies on being unpredictable so short IDs cannot be precomputed before a block exists or ground across blocks. Every other RAND_bytes call site in this tree (bip32.cpp:203, db.cpp:2462, db.cpp:2469) checks for != 1 and fails closed; this one now does too. The caller falls back to full-block relay. TryReconstructBlock sized a vector directly from the wire. nTotal is the sum of two deserialised vector lengths, and serialize.h bounds a vector only by MAX_SIZE (0x02000000), so once the P2P handlers are wired a single small message could ask this node to default-construct ~33M CTransactions. The smallest a transaction can serialise to is 10 bytes, so no block within MAX_BLOCK_SIZE holds more than MAX_BLOCK_SIZE/10 of them; anything above that is not a block this node could accept under any circumstance. Rejecting falls back to full-block relay, which is always correct. Neither is reachable today -- nothing feeds these functions from the network yet -- but both are latent the moment the message handlers land, which is the wrong time to be finding them. test_compactblock (17 checks) and all 14 selftests pass with both in place. --- src/compactblock.cpp | 22 +++++++++++++++++++++- 1 file changed, 21 insertions(+), 1 deletion(-) (limited to 'src') diff --git a/src/compactblock.cpp b/src/compactblock.cpp index 3999ab7..1ca6118 100644 --- a/src/compactblock.cpp +++ b/src/compactblock.cpp @@ -48,8 +48,16 @@ bool BuildCompactBlock(const CBlock& block, CCmpctBlock& out) out.nBits = block.nBits; out.nNonce = block.nNonce; + // Upstream ignored the RAND_bytes return value here.
