2026-09-05Merge upstream/main into the forkbitflash-maintainer
Brings the nine commits that are actually the latest on our lineage: isolated testnet parameters and genesis, optional 2 MB large pages for RandomX, and five README changes. This is what "up to date" means here -- not the 1.2.2x tags, which carry higher version numbers but were cut 2026-07-30, three weeks before the line we ship, and which upstream/main does not contain. Three conflicts, all resolved toward upstream's structure while keeping what this fork knows: main.cpp -- upstream moved genesis construction into BuildGenesisBlock() so mainnet and the new testnet can share it. Verified byte-for-byte before taking it: MAINNET_GENESIS_TIMESTAMP, _TIME (1753315200), _NONCE (3141), _HASH, _MERKLE, the scriptPubKey, nBits and nVersion all equal what this tree built inline. The mainnet genesis hash is unchanged and the asserts still guard it. Kept our warning about never editing those inputs, and kept our note that 1753315200 is 2025-07-24, not 2026 -- upstream's comment on that constant states the wrong year. net.h -- DEFAULT_PORT = htons(8433) becomes MAINNET_PORT/TESTNET_PORT in host order. Nothing is lost: net.cpp's GetDefaultPort() applies htons() itself and is what every caller uses, so the value reaching a sockaddr is unchanged and mainnet stays on 8433. selftest.cpp -- the known-tests string had diverged in both directions. Took the union: upstream's network-params alongside our payout-ledger, rather than dropping either. Gates: 15/15 selftests (our 14 plus upstream's network-params), consensus constants unchanged against e4f898c except the pre-existing MAX_BLOCK_SIZE_GEN, mainnet genesis intact, compactblock's 17 checks still pass, money-log check ok, GNU_STACK RW.

2026-09-02log: reject a -maxdebugfilesize that is not a plain count of MBbitflash-maintainer
atoi64() is strtoll() with the endptr discarded, so it yields 0 for anything it cannot read. -maxdebugfilesize=1G and -maxdebugfilesize=1024MB both parsed as 0, which the roll reads as "never roll" -- indistinguishable from requesting that deliberately, and silent. An operator who wrote a unit suffix got no rotation and no warning. Only a negative value said anything. The multiplication was unchecked as well: a large enough N made nMB * 1024 * 1024 overflow to a negative cap, which disables the roll too. Parse with strtoll() and its endptr, and reject trailing characters, ERANGE, negatives, and any value that would overflow the byte cap -- each reported with the reason and the cap being kept. 0 still means never roll and is still accepted without comment.
2026-09-02log: demote the four lines that were 90% of debug.log behind /debugrelaybitflash-maintainer
A 13-hour production capture was ~71% "sending: tx", ~16% "Nostr: discovered .btf peer", ~5% "Relaying wtx", and ~43% of raw lines were CBlock/CTransaction dumps -- all already under -debug, which operators run permanently, so -debug was useless as a filter. The category mechanism gains a verbose tier: "relay" and "nostrdiscovery" are accepted only with the new /debugrelay flag (which implies /debug); everything else keeps its current gate. Demoted, with message text unchanged for anyone grepping it: net.h "sending: tx (N bytes)" (BeginMessage/EndMessage/ AbortMessage all pick the category from the command, so no orphaned "(N bytes)" fragments leak into a plain -debug log) main.cpp "Relaying wtx", "received block:" + CBlock::print, and the BitcoinMiner block dump nostr.cpp "Nostr: discovered .btf peer" -> "nostrdiscovery" Pool/worker/payout, [payout], BLOCK ORPHANED/ACCEPTED and share flow lines are untouched. Because LogPrint dedup keys on category, demoted lines also keep their burst collapse under /debugrelay. Closes #35
2026-09-02log: cap debug.log in-process, and ship a logrotate policybitflash-maintainer
debug.log grew without bound (production: 1.95 GiB, 51-129 MB/day). Nothing shrank it once the process was up -- there is no ShrinkDebugFile in this tree, and upstream's only ran at startup. OutputDebugStringF now rolls the file to debug.log.old when it passes -maxdebugfilesize (MB, default 1024, 0 disables). The write path already opens and closes the file per line under one lock, so the rename-and-reopen is a few lines inside that lock and no fd can be stranded mid-roll. contrib/logrotate/bitflash-debug.logrotate is the longer-term policy (size 1G, rotate 4, compress, missingok, notifempty, copytruncate); copytruncate keeps the writer's append handle valid across rotation. Closes #34
2026-09-01wallet: refuse to mint a wallet a headless node never asked forbitflash-maintainer
v1.2.20 makes SQLite the default backend for a datadir that holds no wallet. 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 <datadir>/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.
2026-09-01Merge upstream v1.2.20 into the forkbitflash-maintainer
Merges upstream tag v1.2.20 (6aa3dade) into our 1.2.19+sec tree. The merge base is bc3de30's descendant 9e39a50 -- upstream's own v1.2.19 -- so this is an ordinary three-way merge, not a replay. Five conflict blocks in four files, all resolved below. No consensus change. CheckBlock, ConnectBlock, DisconnectBlock, ConnectInputs, AcceptBlock, AcceptTransaction, GetNextWorkRequired and GetBlockValue hash identical to v1.2.19; script.cpp and script.h are byte-identical on both sides. main.cpp is +3 lines and main.h +2, all wallet-backend plumbing. rpc.cpp is untouched, so the payout ledger arrives unchanged. Makefile, VERSION. OURS, renumbered. 1.2.20+sec, for the same reason 1.2.19 carried +sec: this tree is not the upstream release of that number and the string names every release artifact. Makefile, AppImage recipe. OURS for the AppDir path, THEIRS for the bundled library. Upstream's hunk reverts the icon paths to a hardcoded /tmp/bitflash.AppDir, which is the local-user pre-placement hazard the fork moved out of /tmp in the first place; taking their side wholesale would have reintroduced it silently, inside a conflict about something else. The AppDir stays $(APPDIR), and libsqlite3.so.0 joins the bundled list, which the new backend genuinely needs. src/Makefile, src/makefile.mingw, HEADERS. BOTH. Ours drops market.h, theirs adds wallet_sqlite.h; the resolution does both. NODE_OBJS auto-merged correctly in both files -- obj/wallet_sqlite.o present, obj/market.o still gone -- and was verified rather than assumed, because that line has trapped this fork before. src/selftest.cpp, known-tests list. BOTH, union. Upstream adds eight wallet-storage tests, we keep payout-ledger. The dispatch chain itself auto-merged and still routes payout-ledger to RunPayoutLedgerSelfTest. Hardening verified intact after merge: the TLS 1.2 floor in nostr.cpp, the /rvrelay pin, opt-in managed Tor, strict sig3-on-onion descriptor verification, and the marketplace removal. Upstream shipped no build logs or __pycache__ this time; the three added files are docs/storage.md and src/wallet_sqlite.{cpp,h}. The SQLite backend this release introduces is NOT enabled here. An existing wallet.dat resolves to Berkeley DB on every branch of the new selection logic, and the conversion wizard is GUI-only and not compiled into the headless node. The review findings that gate ever turning it on -- the non-atomic backend marker, the connection-wide WriteHDMaster transaction, and the encrypt-swap crash window -- are recorded on the tracker, not fixed here.
2026-08-26build: make managed Tor opt-in, and ignore upstream's committed build artifactsbitflash-maintainer
Upstream 1.2.19 auto-starts a bundled tor whenever one sits next to the executable: silent transport change, a spawned process, a new hidden service, and descriptors going out with meeting_node="rendezvous-pending" -- on nodes that never asked, against this fork's pinned-relay posture. The behavior moves behind the explicit /automanagedtor; /managedtor stays as before. Also ignore build-*.log, __pycache__/ and *.pyc so the five artifacts stripped from the release merge cannot come back.
2026-08-26Merge upstream v1.2.19 into the forkbitflash-maintainer
Merges upstream tag v1.2.19 (9e39a50) into merge/upstream-1.2.18 (991853f). Unlike the 1.2.15->1.2.18 replay, bc3de30 is a true ancestor of our branch via a9b4f89, so this is an ordinary three-way merge with merge-base bc3de30. Delta: 36 files, +3265/-163, the Tor onion transport (managed Tor, signed direct onion endpoints, onion-only dial mode) and the nHDNext restore fix. src/main.cpp, main.h, script.cpp/h and db.cpp/h are byte-identical between the two tags, and the poll() socket loop carries no diff hunks, so the merge is consensus-neutral and the soak-tested socket paths are unchanged. relay/ is untouched; the payout ledger (rpc.cpp) is untouched. 7 conflict blocks in 6 files, resolved as follows. Makefile -- VERSION. Ours: stays 1.2.19+sec with the naming comment updated, so artifacts from this tree cannot be mistaken for the upstream release. src/Makefile, src/makefile.mingw -- HEADERS list. Ours (no market.h) plus their tor.h. NODE_OBJS auto-merged correctly: no market.o, tor.o present. src/selftest.cpp -- known-tests list. Union: payout-ledger (ours) and managed-tor (theirs). src/main_gui.cpp -- one block. Our /dumpaddresses kept; their BtfStopManagedTor() on the StartNode failure path taken. The /rvrelay pin, /noannounce and the marketplace removal auto-merged and were verified intact. src/nostr.cpp -- two blocks in ResolveDescriptor. Signature takes both out-params (our fExchangeOk, their rawOut). The body keeps our drain-to-EOSE read -- returning early poisons the pooled socket for the next caller -- and adds their rawOut capture. Our TLS 1.2 floor (SSL_CTX_set_min_proto_version) is untouched by this merge; upstream 1.2.19 still has no floor of its own. Upstream's release commit also added four build logs and a compiled Python cache (build-1219.log, build-17.log, build-appimage.log, build-node.log, scripts/__pycache__/bitflash_chain.cpython-313.pyc). Removed here; they are build output, not source.
2026-08-23Merge upstream v1.2.18 into the forkbitflash-maintainer
Merges upstream tag v1.2.18 (bc3de30) into our 24 commits. The merge base is a259215, upstream's own commit, whose src/ tree is byte-identical to 68de575 -- our commits were replayed onto a259215 first so that git had a real base to work from. That produced 28 conflict hunks in 9 files instead of the 21 conflict events / 51 hunks a direct cherry-pick onto the tag would have forced, most of which were artifacts of lifting our commits away from their own predecessors. No consensus change. main.cpp's GetBlockValue, GetNextWorkRequired, ConnectInputs, ConnectBlock, CheckBlock, AcceptBlock and AcceptTransaction are untouched by this merge; script.cpp, serialize.h and randomx_pow.h are identical on both sides. The frozen-chain oracle reproduces the pinned UTXO root 116a2b6b... byte for byte, and the merged binary loads the same 12,586-block chain to the same tip aac622f0a3b2f8... with all blocks re-verified and none rejected. Which side won, per file and per hunk. src/rpc.cpp -- 15 hunks. 1. RebuildJob transaction selection. THEIRS for the multi-pass loop and the nFees fix, OURS for the cap. Their vfAlreadyAdded/fFoundSomething loop lands dependent transactions that our single pass dropped deterministically, and their nFees is accumulated across the scan instead of being redeclared inside it -- ours passed a hardcoded 0 to GetBlockValue, so every pool block built here discarded its fees. But their bound is MAX_SIZE/2 = 16 MB, and MAX_BLOCK_SIZE is 1 MB, so their template can exceed what their own CheckBlock accepts. Cap kept at MAX_BLOCK_SIZE/2, with our inner break so a single pass cannot overshoot by more than one transaction. Our RebuildJob sync gating and deaf-node detection are kept; upstream has none. 2. struct PendingPayout. OURS for the key, THEIRS for paidTxids. Their id is the string "block-<height>", which is height keying -- the exact bug 44849e6 fixed after a 280-block reorg left ~14.4k BTF owed against blocks that no longer existed. Height keying also lets the crash-recovery probe match the previous round's transaction after a reorg and silently skip a miner, so their id is dropped entirely and blockHash stays the key. paidTxids is taken because it is what makes an entry survivable. Their nextAttempt and our retryAfter are the same concept under two names; ours is kept and theirs dropped. matureAtHeight gained an explicit = 0, which neither side had in our style of initialiser. 3./4. Ledger writer and loader. Mechanical follow-ons of 2. The loader keeps ours and takes their tolerance for an entry with no usable height, guarded so it cannot fire on a well-formed entry. One redundancy was removed rather than merged: their unguarded `if (obj.contains("blockHeight")) get<int>()` sat two lines above our is_number-guarded version, and an unguarded get<int>() on a malformed value throws out of the whole loop, losing every entry in the file. Verified against the live production pending_payouts.json (2 entries, keys amounts/blockHash/blockHeight/matureAtHeight): loads both. A file in the new shape, with retryAfter and paidTxids, also loads. 5. Insertion point after the loader. BOTH. Our PayingRecord/gPaying in-flight ledger and their PoolRoundProof/PoolRoundToJson are disjoint features that landed at the same offset. Both kept, in full. 6. Writer tail. THEIRS, copied into our writer. Checking fclose() matters here because fclose is where the buffered write actually reaches the OS: renaming a short .tmp over a good file is precisely the truncation the atomic write exists to prevent. The Windows remove()-before-rename() is required because rename() there will not replace an existing file. 7. Loader bodies. BOTH -- LoadPaying and LoadPoolRounds are different functions that happened to share a common tail. 8. Function block, 111 vs 36 lines. BOTH, with one deliberate deletion. PayoutBlockStillOnChain, PayoutComment, RecordPoolRound, MarkPoolRoundPaid all kept. WalletAlreadyPaid is DELETED and ReconcilePayouts rewritten, because our reconciliation and their FindRecordedPoolPayout are two answers to the same crash-recovery question and running both would give the same debt two authorities. Their wallet probe wins: it matches structured metadata rather than a comment string, so it can tell two rounds paying the same address the same amount apart. ReconcilePayouts keeps only the job that is still real -- dropping in-flight records the ledger already shows paid, and arming each restored record for its one wallet probe. It no longer touches gPendingPayouts at all; under the new model dropping ledger entries there would reintroduce the loss this merge adopts their model to prevent. Their gPayoutExecMutex/gPayoutThreadRunning re-declarations were dropped as duplicates of ours, and gPayoutExecQueue was not taken: gPaying is the exec queue in this tree, at finer granularity. 9. QueuePayouts signature. THEIRS for the round-proof arguments, OURS for the type of blockHash. It stays a uint256 and is converted to hex only where the round proof needs text -- a ledger key that has been through ToString() is a key that can be compared wrong. 10. Maturity policy. OURS. matureAtHeight = blockHeight + COINBASE_SPENDABLE_DEPTH (120), not + COINBASE_MATURITY (100). At depth 100 the block's own coinbase is still 20 blocks short of spendable, so the payment must come from unrelated mature coin and the pool runs a permanent float. Our own history contradicts itself here -- d6972a0 argued for COINBASE_MATURITY citing "96% of 934 payments", 44849e6 reversed it on the grounds that the measurement was taken while the node was alone on a private fork paying itself. HEAD's position is kept. This is a considered disagreement with upstream, not an oversight. The live production ledger confirms it: both entries have matureAtHeight - blockHeight = 120. 11. Comment above FlushMaturePayouts. Rewritten to describe the merged design. 12. FlushMaturePayouts, the central difference. THEIRS for the model. The ledger entry now survives on disk until every recipient has a txid, instead of being erased as soon as its payments were handed off -- the old ordering left a window where the debt was described by nothing at all, and a container restart on 2026-07-30 silently dropped ~1,156 BTF through it. Our gPaying is kept on top as the in-flight working set, because it carries the per-recipient retry and deferral state a per-round nextAttempt cannot express. It is explicitly a cache derived from the ledger, not a second record of debt: if it were lost the next flush would rebuild it. 13. PayoutThreadFn, 79 vs 70 lines. OURS for the loop and the reorg re-check, THEIRS for the per-recipient dedupe. The re-check on every attempt is load-bearing and upstream has no equivalent -- it decides once, at maturity, and a payment can sit through hours of retries during which the reorg that kills its funding block can land. Their paidTxids check is taken, against the ledger rather than against the batch. Our deferral policy is kept: waiting for coin is not a failure and must not consume the retry budget. Two fixes upstream does not have are folded in here rather than deferred to a follow-up commit: - FindRecordedPoolPayout runs once per record, on its first attempt, not on every attempt. It is a linear scan of mapWallet under cs_mapWallet, per recipient; upstream repeats it for every retry, which with 2000 rotating payout addresses and a budget of 1440 retries is a full wallet scan per address per minute for a day. The question it answers can only change across a restart, and every restart re-arms the flag. - The ledger file write no longer happens under gPayoutLedgerMutex in the per-recipient loop. SavePendingPayoutsLocked was split into a serialise step that needs the lock and a write step that does not, so the mutex is held only long enough to read the structure. The orphan scan in FlushMaturePayouts was likewise restructured so the ledger mutex is not held across PayoutBlockStillOnChain's cs_main acquisition. One case the merged model created and neither side handled: under survives-until-fully-paid, our GIVING UP path dropped the in-flight record but left the recipient owed in the ledger forever, so every later flush would explode it again -- a forfeit that silently becomes an infinite retry. ForfeitPayoutRecipient writes the amount off so the entry can retire. 14. QueuePayouts call site. Follow-on of 9. 15. ThreadRPCServer startup. BOTH. LoadPoolRounds added; LoadPaying and ReconcilePayouts stay, and stay before the payout thread starts. Crash safety, stated as the property that must hold: after kill -9 at any point, restart pays each recipient exactly once. Before SendMoney, the ledger has no txid and the payment is retried. Between SendMoney and the ledger write, the wallet holds the transaction and the first-attempt probe finds it. After the ledger write, paidTxids suppresses it. If the in-flight file is lost entirely, the ledger rebuilds it and the probe still covers the middle window. src/nostr.cpp -- 3 hunks. THEIRS as the base, with two things restored from ours. Theirs loads the Windows ROOT certificate store, which ours lacks and genuinely needs, since OpenSSL's default verify paths are usually empty there and our version would fail closed. But the plan's claim that theirs is a superset of our 06bceb4 is FALSE: upstream's nostr.cpp contains no min_proto_version, no TLS1_2, no SSL_OP_NO_*, and no set_options anywhere, so taking it wholesale would have removed the TLS-version floor outright. Restored. Second, their SSL_get_verify_result check sits after a successful handshake, where with SSL_VERIFY_PEER set it is nearly dead code -- a bad certificate aborts inside SSL_connect. The reporting belongs in the failure branch, which is where the merge put it; their post-handshake duplicate was dropped. Our relay-list and socket-pooling hunks auto-merged and were verified intact. src/net.cpp -- 1 hunk. THEIRS. Their guard, hSocket == INVALID_SOCKET || pnode->hSocket != hSocket, subsumes ours and additionally catches descriptor recycling, which ours did not; our version also referenced a pnode that only existed in the select() loop. Our other db34011 hunk, nulling pnode->hSocket in the poll-failure branch, auto-merged and was NOT re-applied -- plan section 7 Batch D says to re-apply it, and that instruction is stale. Two pieces of residue the merge left behind were cleaned up: a comment still describing select() semantics, and a pnode->hSocket != INVALID_SOCKET guard made redundant by a continue two lines above it. src/main.cpp -- 2 hunks. h1 BOTH, pure add/add adjacency between our ParticipantHashThreadCount and their SecureClear forward declarations. h2 OURS, and their handler discarded: 44004e3 no-ops checkorder/submitorder but keeps market.cpp and market.h, whereas 11766be deletes the marketplace outright including CRequestTracker, subscribe/publish and mapProducts. Ours is strictly more. src/main_gui.cpp -- 2 hunks. BOTH, additive on both sides. Our /payoutaddr, /payoutfile and /hashthreads alongside their /stratumbridge and /stratumbridgeport. src/btfrv.cpp -- 1 hunk, not predicted by the plan. False adjacency: our INVALID_SOCKET check and their #endif landed at the same offset. Ordering is load-bearing -- our check goes inside the #else arm, before the #endif, or the non-proxy build silently loses it. The BITFLASH_NODE_BUILD arm already returns early, so both paths now have the check. Makefile -- 2 hunks plus a hazard with no conflict marker. THEIRS for both dependency-fetch recipes: checkout --detach FETCH_HEAD followed by test "$(git rev-parse HEAD)" = "$(..._COMMIT)" asserts the pin actually landed, where ours only checked it out. Everything of ours that they lack is kept: the appimagetool 1.9.1 release pin with a sha256 check, where upstream fetches the mutable "continuous" tag and executes it undigested, and the move of both the tool and the AppDir out of /tmp, where any local user could pre-place an executable and have it run as whoever runs make. The hazard: both sides added a pin block in a different place, so git merged both, outside any conflict region. SECP256K1_COMMIT and RANDOMX_COMMIT ended up assigned twice, near L16 and near L44, and GNU Make takes the last := -- a naive resolution would have silently built against our old secp256k1 pin while appearing to adopt upstream's. The duplicate block was deleted by hand. Each of the four variables is now assigned exactly once, and make -n resolves SECP256K1_COMMIT to 7fecac74 with 6e2c8bc4 appearing nowhere. Also applied here, from plan phase 4: SECP256K1_COMMIT moved to upstream's 7fecac74aed8e1fd9078380d67dd04663705c989 so signature validation matches the binaries the rest of the network runs. secp256k1 was rebuilt from scratch against the new pin on the build host and the checked-out dependency commit verified. RANDOMX_COMMIT already matched at 1e9d4b2d and is unchanged. src/Makefile, src/makefile.mingw -- 1 hunk each, both the HEADERS list. Ours drops market.h, theirs adds proxy.h; the resolution does both. Taking theirs wholesale would have left the Makefiles referencing a header git had already deleted in our favour, silently, without a conflict. Files the plan predicted would conflict and did not: net.h, main.h and db.cpp auto-merged. Verified rather than assumed. net.h carries both our BTF_MSG_WAIT_MAX_SECS work, including the constructor fix from 2d84982 that starts nMsgWaitSince and nMsgWaitSize at 0, and their comment rewrite with extern int nPeersWatched. The dead members that fix removed are gone from every file. Deviations from MERGE-1.2.18-PLAN.md. - Section 6's mechanism was not used. Replayed onto the real merge base and merged, rather than cherry-picking onto the tag. Same result, 28 hunks instead of 51. - Section 2 calls 09ff575 a superset of our 06bceb4. It is not; upstream has no TLS-version floor at all. Ours restored on top of theirs. - Section 7 Batch D says to re-apply our db34011 line into their poll-failure branch. It auto-merged; re-applying would have duplicated it. - Section 2 says do not take the stratum bridge. It is taken, and left off. fStratumBridge defaults false in main.cpp, the thread is only spawned when /stratumbridge is passed, and the listener binds 127.0.0.1 only. Excising it would cost real divergence and future conflict for no gain while it is disabled. Its defects -- select()/FD_SET on a node that can hold more than 1024 descriptors, and an uncapped thread per connection -- are real only when it is enabled and are being reported upstream separately. - Section 7's staged batches were not run as separate gated commits. The conflict surface is interleaved within single functions, chiefly the payout ledger, and splitting it would have meant committing states that do not build. The merge is one commit, as briefed. - Batch F's two fixes are folded into hunk 13 rather than deferred, because they change the same lines the resolution rewrites. - The plan did not anticipate the btfrv.cpp conflict, the duplicate pin block, the market.h trap in the two Makefiles, or the give-up/infinite-retry interaction created by adopting upstream's ledger model.
2026-08-23size thread pools by the cores we are allowed, not the ones the host hasbitflash-maintainer
std::thread::hardware_concurrency() reports the MACHINE's core count. 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. (cherry picked from commit b3bee16f3eef8982bff1174bd9d0a9c21473732c)
2026-08-23pool: refuse jobs when no peer has reported a height for 20 minutesbitflash-maintainer
The peer-height gate replaced a tip-age check that was wrong in both directions. 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. (cherry picked from commit 0800c18faf703b4acde1b131d0b742d37a86d92b)

A pool started with /rvrelay=ONE still spawned an accept thread for every Nostr-discovered relay (BtfAllRelays always merged g_discoveredRelays), and each thread optimistically overwrote the advertised meeting node before registering -- so a discovered Tailscale-only relay (a mesh host) flapped the published .btf descriptor and public miners could not connect. fBtfRelayPinned (set only when /rvrelay parses) makes BtfAllRelays return exactly the pinned list. Also validate the /rvrelay value at parse time: with the pin in place no discovered relay can mask a typo. (cherry picked from commit 0a4d2b02fa5382c5e788b5f0e2f8a844695dec47)

2026-08-20randomx: optional 2 MB large pages for the cache, dataset and scratchpadsmischief
RandomX reads its 256 MB cache, 2 GB dataset and per-VM scratchpads at random, so most accesses miss the TLB on 4 KB pages. Requesting 2 MB pages recovers roughly a tenth of the hash rate. Each allocation tries large pages first and falls back to normal pages when the pool is not reserved, so nothing regresses when hugepages are unavailable. -nolargepages opts out, and the diagnostics report which allocations got large pages.

2026-08-19wallet/docs: SQLite is the default backend, not experimentalbitflash
Drop the "experimental" label from the wallet code and docs now that SQLite is the default backend for new wallets, is coin-proven, and carries encrypt, backup, atomic seed writes, and the storage diagnostics. - main_gui.cpp: -help text, the unknown-backend error (SQLite is no longer "experimental" and Berkeley DB is no longer "the default"), and the startup banner ("Wallet backend: SQLite"). - walletcmd.h: the export command comment. - docs/storage.md: rewrite the SQLite section from staging-only ("runtime still opens Berkeley DB", "no runtime backend flag exists yet") to the shipped state -- default backend, conversion wizard, per-backend ops -- and reframe the migration order as shipped in v1.2.20.
2026-08-19gui: harden the restart relaunch (ultra edge cases)bitflash
Follow-up to the Restart Now button. 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. GUI/process wiring only; wallet code unchanged, suites still green.
2026-08-18wallet: make SQLite the default backend for new walletsbitflash
A fresh install with no wallet.dat now starts on the SQLite backend and creates wallet.sqlite, instead of a Berkeley DB wallet.dat. The choice is recorded in a plain-text <datadir>/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. All wallet suites pass.
2026-08-18wallet: one-shot storage commands honour -walletbackend=sqlitebitflash
-walletstorageaudit, -walletstoragecheck and -backupwallet all read wallet.dat regardless of the selected backend. Under -walletbackend=sqlite that is wrong, and for backup it is dangerous: it silently backs up the stale plaintext wallet.dat instead of the live wallet.sqlite. - ScanWalletRecords() routes to the active SQLite store instead of a Berkeley DB cursor (it returned an error under the runtime before). This is the single choke point audit and check scan through. - WalletSQLiteRuntimeOpenReadOnly() opens wallet.sqlite for scanning without loading or validating records, so the pre-load diagnostics can inspect a wallet the loader would refuse. main_gui opens it for audit/check when the SQLite backend is selected (and rejects an unknown backend value there too). - BackupWallet() copies wallet.sqlite (checkpoint, then the temp/old/rename dance; a checkpointed SQLite file is self-contained, no lsn_reset). wallet-sqlite-encrypt self-test proves routing on a datadir where the SQLite wallet is encrypted and wallet.dat beside it is still plaintext: audit with the flag reports the encrypted seed, without it reports the plaintext one; the SQLite backup carries no plaintext key and loadchecks as a standalone wallet.
2026-08-18wallet: clearer refusal for an empty or misnamed SQLite backendbitflash
Review follow-up on the SQLite activation. Two guards, both fail-closed; neither is a correctness fix -- FinishLoadedWallet already refuses a missing default key -- but they make the refusal say what happened: - an empty or non-wallet wallet.sqlite is refused with "no default key record; it may be empty or not a wallet export", instead of the generic "no usable default public key" that reads as corruption; - a misspelled -walletbackend value (e.g. sqlit) is refused instead of silently falling through to Berkeley DB; -walletbackend=bdb is accepted as the explicit default.
2026-08-17wallet: run the node on a SQLite backend (opt-in)bitflash
Adds -walletbackend=sqlite: an opt-in flag that runs the node on <datadir>/wallet.sqlite instead of wallet.dat. It requires an export to exist first (no silent migration) and prints a step-by-step guide when one does not; wallet.dat is never opened or touched, so a plain restart goes back to Berkeley DB. - LoadWalletFromSQLiteRuntime opens the export read-write, keeps the handle open as the active backend, loads records into memory through the same visitor/reconcile/finish path as the read-only staging load, and never fabricates a default key. - Shutdown checkpoints and closes the SQLite backend; a kill before that loses nothing because WAL + synchronous=FULL already made every committed write durable. - Self-test proves runtime writes persist across a close and reopen. BDB stays the default: nothing activates the SQLite runtime unless the flag is given. One-shot audit/recovery commands still use Berkeley DB.

2026-08-07shutdown: flush wallet.dat on Windows headless stopBitflash
The headless loop installed SIGINT/SIGTERM handlers only under #ifndef _WIN32, so a headless node on Windows never reached the clean StopNode()+DBFlush() path: Ctrl-C, closing the console window, a service stop and OS shutdown all killed it mid-write, and a Berkeley DB wallet.dat left unflushed will not reopen. Install a SetConsoleCtrlHandler that mirrors the POSIX path: set fShutdown and, because the OS terminates us shortly after the handler returns on CLOSE/LOGOFF/SHUTDOWN, block until the main loop signals the flush is done. A 'taskkill /F' is still an uncatchable hard kill by design. Closes #16.

2026-08-04gui: say why the wallet would not open, where the user can see it (#136)Bitflash
Every fatal startup path wrote to stderr and to printf, and on Windows neither reaches anybody. printf is remapped to OutputDebugStringF, so it lands in debug.log inside the data directory. 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.
2026-08-04wallet encryption: the stack from #130–#133, with the two blockers fixed ↵Bitflash
(#134) * wallet: refuse future encrypted wallet formats * wallet: add encrypted key unlock core * wallet: add encryptwallet rewrite command * wallet: read passphrases from stdin or files * wallet: keep the derivation across encryption, and take the logs with it Two things stopped the encryption stack from being safe to merge. 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 <ti@gpm.infra>
2026-08-03wallet: wire -sendto into main(), where it never was (#119)Bitflash
CmdSendTo() has been in walletcmd.cpp since #115 and nothing declared it or called it. The flag was dead: `bitflash -sendto=ADDRESS,AMOUNT` started a node and said nothing, because an unrecognised argument is not an error here. The v1.2.14 notes announce it under "A headless node can finally spend", and the headless Linux binary is exactly the one that does not have it -- `-help` there lists /newaddress and stops. The published Windows binary does have it, because it was built from a working tree that carried these two files uncommitted. So the artifacts disagree with each other and neither matches the tag. This adds only what was missing: the declaration in walletcmd.h, the dispatch in main(), and the -help line. No behaviour change to CmdSendTo itself. Checked on a build of this branch, against a throwaway data directory: -help lists /sendto=ADDRESS,AMOUNT -sendto=NOTANADDRESS,1 "Not a valid address", exit 1 -sendto=<valid>,-5 "Not a valid amount", exit 1 -sendto=<valid>,999 refused on an empty wallet, exit 1 All five self-tests still pass.

2026-08-01docs: bring the README up to the wallet that exists, and make -help print (#106)Bitflash
The README still said deterministic restore was an open issue, told people the mining mode was not remembered between restarts, and wrote every flag in the slash form that MSYS2 turns into a path before the node sees it. Rewritten around the phrase and the file as two backups covering different keys, the -restorephrase note for anyone who made a phrase on 1.2.12, -rescan, the diagnostics report, and the two upgrade reasons measured this week. Also: -help printed nothing at all. This tree remaps printf to OutputDebugStringF, so the usage page went into debug.log, and a -mwindows binary has no console to write to either way -- the one command whose job is to tell you something returned 0 and said nothing. It now takes the real printf and attaches the terminal. The help text was missing -restoredepth, -showderived and the wallet-hd self-test.
2026-08-01wallet: create and restore a recovery phrase (#96)Bitflash
Adds -newphrase, -restorephrase, -restoredepth, -newaddress and -showderived, plus the window buttons that reach the same code. Restore derives forward in batches of 100 and rescans after each, stopping when a whole batch turns up nothing; the phrase is shown on the terminal only, never in debug.log. Proved end to end on a live wallet: paid a derived address, deleted wallet.dat, restored from the twelve words and recovered the coin. Coins on the pre-seed default address do not come back, and the command says so.
2026-08-01wallet: derive the key pool from a seed, so a phrase could bring it back (#93)Bitflash
Adds BIP32 derivation behind the wallet key pool, with no user-facing way to create a seed yet. wallet.dat gains hdmaster/hdchaincode/hdnext; the mnemonic is never stored. TopUpKeyPool derives m/n' when a seed exists and falls back to a random key, with a log line, if derivation fails. New -selftest=wallet-hd, wired into make tests on both platforms.

2026-08-01wallet: walk the chain for coins a key owns but the wallet never saw (#88)Bitflash
A transaction only entered the wallet when its block arrived over the network, so a key added afterwards was invisible: coins on the chain, private key in wallet.dat, balance zero. /importwallet has always ended that way -- it writes the keys and the money never shows up, which looks exactly like a failed import. ScanForWalletTransactions walks the main chain and hands every transaction that IsMine() to AddToWalletIfMine, the same two primitives the live path uses. Wired into /importwallet, and offered as /rescan. It is also the half that any recovery-phrase feature has to stand on: deriving keys from twelve words is easy, and without this a restore restores nothing.
2026-08-01mine: remember whether this node was mining, with the command line winning (#84)Bitflash
2026-07-31wallet: believe the chain about what has already been spent (#62)Bitflash
fSpent lives in wallet.dat and is written when this node spends something. A wallet.dat restored from backup, or copied and used on another machine, carries whatever that flag was when the copy was taken -- so it can say "unspent" about coins the chain shows as gone. The balance reads high and nothing contradicts it until a send is attempted against coins that do not exist. #47 is about this shape of problem and #40 is someone living through it; Bitcoin fixed the same thing in 53d508072. On startup, after the block index is loaded and before anything reports a balance, walk the wallet and mark spent whatever the transaction index says is spent. One direction only. Marking spent when the chain says spent is safe; clearing the flag because the chain has not caught up would offer up coins already on their way out. fSpent is one flag per transaction rather than per output, which is how 0.1.0 has always worked -- CommitTransactionSpent already marks a whole previous transaction when it spends any part of it -- so this matches rather than changing the model. It reports every run, including the runs where it finds nothing, with a breakdown of why: RescanSpentFlags() : examined 17, already-spent 0, not-indexed 17, corrected 0 A check that speaks only when it finds something is indistinguishable from one that never ran, and that confusion has cost this project real time. The breakdown earned its place immediately: it is how the test below turned from a guess into an answer. Verified running against a wallet with 17 transactions and against an empty one, with no false corrections in either. 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.
2026-07-31db: verify the tail of the chain on startup and back out of a bad tip (#61)Bitflash
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 -- had no way to notice. 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.
2026-07-30mine: hash on every core instead of one (#52)Bitflash
Satoshi left a note above ThreadBitcoinMiner in 2009: //// todo: start one thread per processor, //// use getenv("NUMBER_OF_PROCESSORS") Nobody did, and it stopped being a nicety when the proof of work became RandomX. 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.
2026-07-30wallet: export and import keys as text (#49)Bitflash
The last door out. 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.
2026-07-30wallet: make wallet.dat a file you can actually back up (#46)Bitflash
* wallet: make wallet.dat a file you can actually back up Issue #40: a wallet.dat copied out on its own will not open anywhere else. 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.
2026-07-30main: make /gen actually mine (#42)Eric
nMineMode defaults to MINE_RELAY (0) and ParseStartupArguments() never changed it, so a node started with /gen would spawn ThreadBitcoinMiner, enter BitcoinMiner(), hit if (nMineMode == MINE_RELAY) return true; and return before doing any work. 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. Verify with `nMineMode = 1` at startup. Co-authored-by: Claude Opus 5 <noreply@anthropic.com>
2026-07-29db: catch BDB exceptions so unreadable files fail cleanly (#34) (#38)Bitflash
Berkeley DB throws when it cannot open a file written by another platform's build (e.g. BDB 5.3 wallet read by 6.2). 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. Closes #34 Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
2026-07-29build: headless Linux node that does not need libGL (#37)Bitflash
The GUI build requires libGL at load time even when started with -nogui. 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-<version>-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. Verified on Debian 13: ldd bitflash-node | grep -iE 'libGL|glfw|X11' -> nothing ldd bitflash | grep -iE 'libGL|glfw' -> libglfw.so.3, libGL.so.1, libGLdispatch.so.0 and at runtime, from an empty datadir: btfseed: reached ygffz37...btf via 90.156.222.107:8434 rendezvous: registered at 90.156.222.107:8434, waiting for a dial self-resolve OK (meeting_node=90.156.222.107:8434) btfpeers: kept 15 of 15 descriptor(s) first block at ~30s, 3182 blocks accepted, synced to the tip The GUI builds on Linux and Windows were rebuilt and are unaffected.
2026-07-29net: compiled-in bootstrap seeds, so a first run does not need a relay (#36)Bitflash
* net: compiled-in bootstrap seeds, so a first run does not need a relay A node with no cache has only the Nostr relays. 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. Recording which relay a seed was on would rot the moment it failed over, which is exactly the failure this project spent weeks chasing -- advertising a rendezvous somebody is not registered at. 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. Empty is valid: discovery falls back to Nostr exactly as before. /btfseed=ADDRESS:ENCHEX (repeatable) appends at runtime, for testing and for private networks. Tested against the live network, clean datadir, no cache, three seeds carrying no meeting node: btfpeers: no cache yet, falling back to seeds btfseed: trying 3 seed(s) across 3 relay(s) btfseed: reached q5jxyzn...btf via 90.156.222.107:8434 btfseed: 3 seed(s) answered * net: add the Almaty bootstrap node to the seed list Dedicated node, no wallet balance, no mining, running beside the rendezvous relay on the same host. It exists only to answer a first dial. Fresh datadir, no flags, compiled list only: btfpeers: no cache yet, falling back to seeds btfseed: trying 1 seed(s) across 3 relay(s) btfseed: reached ygffz37...btf via 90.156.222.107:8434 btfseed: 1 seed(s) answered btfpeers: kept 2 of 2 descriptor(s) 5.2 seconds from nothing to a peer, against 36s for a cold start that had to go through the relays. The seed then handed over two more peers by exchange, which the cache keeps for next time.
2026-07-29main_gui: implement /port, which net.cpp already documented (#28)Bitflash
net.cpp has described nListenPort as "tunable via /port" since it was written: unsigned short nListenPort = DEFAULT_PORT; // local P2P port (tunable via /port) Nothing ever parsed the option. The port was fixed at 8433, so a second node could not start on a machine already running one -- StartNode fails the bind and the node comes up with no networking at all. That makes local multi-node testing impossible, which is how this was found: a two-node test could not be run. Sets addrLocalHost.port alongside nListenPort, or the node announces a port it never bound. An out-of-range value is rejected with a message and the default kept, rather than silently wrapping through the unsigned short cast.
2026-07-29Remove peer exchange from main; it was merged unreviewed (#27)Bitflash
PR #25 was opened, reviewed and approved as a single-file change to net.cpp: the .btf peer cache, +169/-0. 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.
2026-07-29Remember .btf peers that answered, and dial them first on start (#25)Bitflash
* net: remember .btf peers that answered, and dial them first on start Discovery depends entirely on the Nostr relays. 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. Sets addrLocalHost.port too, so we do not advertise a port we never bound.

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 <relay>' 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 <nasci.victorio@gmail.com> Co-authored-by: Bitflash Pool Dev <pool@bitflash> Co-authored-by: Victorio Nascimento <155357371+Vic-Nas@users.noreply.github.com> Co-authored-by: Claude <claude@anthropic.com>
