Issue being fixed or feature implemented

Merges the v24.0.0 release back into develop, as the release process asks once master is fast-forwarded. master, v24.0.x and the signed v24.0.0 tag all point to the same commit (938fba5).

What was done?

One merge commit of master into develop.

v24.0.x was cut from develop, so all of its code is already here. Every commit on it that develop lacks by patch is one of these:

a cherry-pick -x of a develop commit;
covered by a develop PR: the index fixes by backport: bitcoin#30221, #32069, #32580, #32875, #32878, #32882, #33212, #34897, #36150 (index unify + relevant fixes) #8042, the mainnet V24 schedule by feat(consensus): activate V24 on mainnet, signaling from November 9, 2026 #7973, the cppcheck CI move by ci: build cppcheck optimised, move it off the test critical path, and cache it for PRs #7966;
release bookkeeping.

Git reports conflicts in many files, because v24.0.x carries adapted copies of develop's changes. All of them resolve to develop's side, which keeps develop's code, translations and version (configure.ac stays at 24.1.0, CLIENT_VERSION_IS_RELEASE false).

Taken from v24.0.0:

doc/release-notes.md: the v24.0.0 release notes. The v23.1.10 notes move to doc/release-notes/dash/.
The man pages regenerated for v24.0.0, replacing develop's older v24.0.0 pages. A few entries (-prune, -par, -parbls, -maxconnections) still trail develop's help text, as they did before, until the next regeneration.
feature_addressindex.py: the v24.0.x test that blocks orphaned while the address index is disabled are removed from it once it is re-enabled.

Release notes:

Individual doc/release-notes-*.md files whose content is in the v24.0.0 notes are removed. This includes release-notes-8018.md, release-notes-8029.md and release-notes-27114.md, whose changes shipped in v24.0.0 without the files.
release-notes-28113.md and release-notes-28414.md also covered descriptorprocesspsbt, which only develop has. They are trimmed to that RPC instead of removed.
Notes for changes v24.0.0 doesn't include stay: fix(rpc): derive active DKG count from membership #7812, fix: sign sporks over their serialized fields and stop using sporks on mainnet #7847, feat: run governance on pruned nodes #7860, backport: bitcoin#28565, bitcoin#28199 #7862, rpc: Add a parameter to sendrawtransaction which sets a maximum value for unspendable outputs. bitcoin/bitcoin#25943, RPC: Accept options as named-only parameters bitcoin/bitcoin#26485 and mempool / rpc: add getprioritisedtransactions, delete a mapDeltas entry when delta==0 bitcoin/bitcoin#27501.

How Has This Been Tested?

macOS arm64 against depends, --enable-debug --enable-werror --disable-hardening --without-gui. dashd, dash-cli and test_dash build cleanly.

src/ is byte-identical to develop's. The only non-doc change is the new feature_addressindex.py case.
Functional tests, all passing: feature_addressindex.py (with the new case) and feature_spentindex.py.
Unit suites, all passing: txindex_tests, blockfilter_index_tests, coinstatsindex_tests, index_migration_tests, baseindex_tests.
lint-python.py, lint-whitespace.py, lint-includes.py and lint-circular-dependencies.py pass.
An independent review checked every non-merge commit in develop..master against develop (by patch, by cherry-pick source, and line by line for the rest), re-merged each v24.0.x merge commit to look for content added in a merge, and checked each release-note file decision.

I did not run the full functional suite locally; CI covers it.

Breaking Changes

None. Develop's code is unchanged; the only non-doc change is the new functional test case.

…Max peers aaa5301 fix(governance): request object votes from nPeersPerHashMax peers (pasta) Pull request description: ## Issue being fixed or feature implemented `SyncManager::RequestGovernanceObjectVotes` is meant to ask up to `nPeersPerHashMax` distinct peers (3 on real networks, unlimited on regtest) for the votes of each governance object, at most once per peer per hour. When the per-object filter was moved into `CGovernanceManager::FetchGovernanceObjectVotes` (77faacc, first released in v23.1.0), the caller started passing `nMaxObjRequestsPerNode` as the helper's `nPeersPerHashMax` argument. The two values are unrelated: one is how many objects to request from a single peer per call, the other is how many peers to ask about a single object. On mainnet `nMaxObjRequestsPerNode` is hard-coded to 1. So after one peer has been asked for an object's votes, the object is dropped from the candidate list for every other peer until the 1 hour `mapAskedRecently` entry expires. During initial governance sync each object's votes are therefore requested from exactly one peer instead of up to three. On testnet and devnets the bound becomes `2000 / enabled masternodes`, which can be larger than 3. Objects that already have 3 asked peers are then re-selected, and that only costs some extra requests. ### Why this is a real problem Code path at c14104b: - [`src/node/sync_manager.cpp#L55`](https://github.com/dashpay/dash/blob/c14104b172a2/src/node/sync_manager.cpp#L55) and [`#L66`](https://github.com/dashpay/dash/blob/c14104b172a2/src/node/sync_manager.cpp#L66): `nPeersPerHashMax` is 3 on real networks. - [`src/node/sync_manager.cpp#L74`](https://github.com/dashpay/dash/blob/c14104b172a2/src/node/sync_manager.cpp#L74): `nMaxObjRequestsPerNode` is 1 on mainnet. - [`src/node/sync_manager.cpp#L86`](https://github.com/dashpay/dash/blob/c14104b172a2/src/node/sync_manager.cpp#L86): `FetchGovernanceObjectVotes(nMaxObjRequestsPerNode, nNow, mapAskedRecently)`. - [`src/governance/governance.cpp#L942`](https://github.com/dashpay/dash/blob/c14104b172a2/src/governance/governance.cpp#L942) and [`#L954`](https://github.com/dashpay/dash/blob/c14104b172a2/src/governance/governance.cpp#L954): the parameter is named `nPeersPerHashMax`, and an object is skipped when `asked_peers.size() >= nPeersPerHashMax`. - [`src/node/sync_manager.cpp#L122`](https://github.com/dashpay/dash/blob/c14104b172a2/src/node/sync_manager.cpp#L122): the inner loop still stops at `nPeersPerHashMax`, but it never gets the chance on mainnet, because the outer filter has already removed the object. - [`src/node/sync_manager.cpp#L297-L298`](https://github.com/dashpay/dash/blob/c14104b172a2/src/node/sync_manager.cpp#L297-L298): initial sync calls `RequestGovernanceObjectVotes` with one peer at a time, so the per-object filter is what decides whether a second and third peer are asked. Before 77faacc the inline loop compared against `nPeersPerHashMax`. The refactor passed the other variable. To show the behaviour directly, I injected a temporary, uncommitted test case into `src/test/governance_inv_tests.cpp`. It uses the existing mainnet `GovernanceInvSetup` fixture, adds one governance object and four connected peers, and calls the real `SyncManager::RequestGovernanceObjectVotes` once per peer, the same way the initial-sync loop does. It then counts the `MNGOVERNANCESYNC` per-object vote requests queued to each peer. The expected result is one request each to peers 1 to 3 and none to peer 4. <details><summary>Unfixed (c14104b): only the first peer is ever asked</summary> ``` $ src/test/test_dash --run_test=governance_inv_tests/object_votes_requested_from_up_to_three_peers --log_level=message Running 1 test case... peer=1 RequestGovernanceObjectVotes returned 0, MNGOVERNANCESYNC (per-object vote request) messages queued=1 peer=2 RequestGovernanceObjectVotes returned -2, MNGOVERNANCESYNC (per-object vote request) messages queued=0 test/governance_inv_tests.cpp:599: error: in "governance_inv_tests/object_votes_requested_from_up_to_three_peers": peer=2 was asked for the object's votes 0 time(s), expected 1 peer=3 RequestGovernanceObjectVotes returned -2, MNGOVERNANCESYNC (per-object vote request) messages queued=0 test/governance_inv_tests.cpp:599: error: in "governance_inv_tests/object_votes_requested_from_up_to_three_peers": peer=3 was asked for the object's votes 0 time(s), expected 1 peer=4 RequestGovernanceObjectVotes returned -2, MNGOVERNANCESYNC (per-object vote request) messages queued=0 *** 2 failures are detected in the test module "Dash Core Test Suite" exit=201 ``` </details> <details><summary>With this PR: three peers are asked, the fourth is not</summary> ``` $ src/test/test_dash --run_test=governance_inv_tests/object_votes_requested_from_up_to_three_peers --log_level=message Running 1 test case... peer=1 RequestGovernanceObjectVotes returned 0, MNGOVERNANCESYNC (per-object vote request) messages queued=1 peer=2 RequestGovernanceObjectVotes returned 0, MNGOVERNANCESYNC (per-object vote request) messages queued=1 peer=3 RequestGovernanceObjectVotes returned 0, MNGOVERNANCESYNC (per-object vote request) messages queued=1 peer=4 RequestGovernanceObjectVotes returned -2, MNGOVERNANCESYNC (per-object vote request) messages queued=0 *** No errors detected exit=0 ``` </details> ### Why it matters On mainnet the vote sync for each governance object has no redundancy. If the single peer picked for an object is slow, lagging or does not answer, the node's vote tally for that object stays incomplete. It stays that way until the hourly re-request after sync, or until the missing votes arrive through normal inventory relay. This affects nodes doing initial governance sync, such as fresh nodes and nodes restarting after a long sleep. There is no consensus or funds impact. The effect is slower and less reliable convergence of governance vote tallies. The regression has shipped since v23.1.0. ## What was done? Pass `nPeersPerHashMax` instead of `nMaxObjRequestsPerNode` as the first argument of `FetchGovernanceObjectVotes` in `SyncManager::RequestGovernanceObjectVotes`. ### Why this is the correct minimal fix The callee's parameter is the per-object peer cap, and the caller already computes the correct value (`nPeersPerHashMax`) and uses it for the matching inner-loop break. Passing it restores the pre-77faacce semantics exactly: an object stays a candidate until 3 distinct peers (unlimited on regtest) have been asked within the last hour. `nMaxObjRequestsPerNode` keeps its own role as the bound of the per-call object loop, so the number of objects requested from each peer per call does not change. No other caller of `FetchGovernanceObjectVotes` exists. A strong type for the argument, or a rename, would stop this kind of mix-up in the future, but both are refactors beyond restoring the intended behaviour. ## How Has This Been Tested? - Reproduction above: a temporary test case in `src/test/governance_inv_tests.cpp` that calls `SyncManager::RequestGovernanceObjectVotes` per peer on the mainnet fixture. It fails on the unfixed tree (peers 2 and 3 never asked) and passes with this change (peers 1 to 3 asked once, peer 4 not asked). It is not part of this PR. `RequestGovernanceObjectVotes` is a private member, and the harness reached it with an explicit-instantiation access trick, which is not acceptable in a committed test. The regtest functional tests cannot observe the bug, because on mockable chains the cap is effectively unlimited both before and after the fix (2000 / MN count vs `SIZE_MAX`). - Unit tests, all passing: `src/test/test_dash --run_test=<suite>` for `governance_inv_tests`, `governance_vote_sync_tests`, `governance_vote_processing_tests`, `governance_vote_wire_tests`, `governance_superblock_tests`, `governance_validators_tests`. - Functional tests, all passing: `test/functional/test_runner.py feature_governance.py feature_governance_cl.py feature_governance_objects.py p2p_govsync_bloom.py`. In the first parallel run, `feature_governance.py` hit an RPC timeout while the host load average was about 100. It passed when rerun on its own. - `clang-format` on the changed lines produces no changes; `test/lint/lint-whitespace.py` passes. Environment: macOS arm64, debug build (`--enable-debug --enable-werror`). ## Breaking Changes None. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

…kgstatus 9581df5 fix(rpc): use a consistent tip height in quorum dkgstatus (pasta) Pull request description: ## Issue being fixed or feature implemented `quorum dkgstatus` can abort `dashd` if the chain tip is disconnected while the RPC is running. The RPC reads the tip once under `cs_main` and drops the lock ([quorums.cpp#L371](https://github.com/dashpay/dash/blob/c14104b172a2/src/rpc/quorums.cpp#L371), [#L373](https://github.com/dashpay/dash/blob/c14104b172a2/src/rpc/quorums.cpp#L373)). For each quorum type it then takes `cs_main` again and calls `GetMineableCommitments(llmq_params, tipHeight + 1)` with that earlier height ([#L429-L430](https://github.com/dashpay/dash/blob/c14104b172a2/src/rpc/quorums.cpp#L429-L430)). `GetMineableCommitments` → `GetNumCommitmentsRequired` → `IsMiningPhase` starts with `assert(nHeight <= active_chain.Height() + 1)` ([blockprocessor.cpp#L889](https://github.com/dashpay/dash/blob/c14104b172a2/src/llmq/blockprocessor.cpp#L889), [#L610](https://github.com/dashpay/dash/blob/c14104b172a2/src/llmq/blockprocessor.cpp#L610), [#L317](https://github.com/dashpay/dash/blob/c14104b172a2/src/llmq/blockprocessor.cpp#L317)). That assert runs on every call, not only inside the mining window. If even one block is disconnected between the two lock scopes, `tipHeight + 1` is greater than `Height() + 1` and the process aborts. The chain can shrink while `cs_main` is released: `invalidateblock`, a reorg that disconnects before it connects, or ChainLock enforcement, which disconnects the conflicting blocks in `EnforceBlock` and reconnects later in a separate `ActivateBestChain` call. Before dashpay#7770 the RPC passed `tipHeight`, so it took a two-block rollback to hit the assert. dashpay#7770 changed it to `tipHeight + 1`, and now a one-block rollback is enough. A related problem sits in the same function, on the masternode-only path: `WITH_LOCK(cs_main, return chainman.ActiveChain()[quorumHeight])` re-reads the active chain ([#L390](https://github.com/dashpay/dash/blob/c14104b172a2/src/rpc/quorums.cpp#L390)). That returns `nullptr` if the chain has dropped below `quorumHeight`, and the result is dereferenced on the next line. ### Why this is a real problem I reproduced the abort on an unmodified `c14104b172a2` debug build with a functional-test-style script. It starts one regtest node with 200 blocks. Six RPC threads call `quorum dkgstatus` in a loop while one thread runs `invalidateblock <tip>` / `reconsiderblock <tip>`. No masternode is needed: the `GetMineableCommitments` call runs on every node. The node aborts within 0.2 s every time (4 of 4 runs). With this PR, the same script runs for 120 s (816,452 `dkgstatus` calls against 44,361 rollbacks) and the node stays up. <details><summary>Reproduction script and output</summary> ```python #!/usr/bin/env python3 import os, sys, threading, time sys.path.insert(0, os.path.join(os.environ["DASH_WORKTREE"], "test", "functional")) from test_framework.test_framework import BitcoinTestFramework from test_framework.util import get_rpc_proxy DURATION = int(os.environ.get("REPRO_SECONDS", "120")) class DkgStatusRollbackRace(BitcoinTestFramework): def set_test_params(self): self.num_nodes = 1 self.setup_clean_chain = True self.extra_args = [["-rpcthreads=16", "-rpcworkqueue=64"]] def run_test(self): node = self.nodes[0] self.generate(node, 200, sync_fun=self.no_op) stop = threading.Event() counts = {"dkgstatus": 0, "rollbacks": 0} errors = [] def dkg_worker(): rpc = get_rpc_proxy(node.url, 0, timeout=30) while not stop.is_set(): try: rpc.quorum("dkgstatus"); counts["dkgstatus"] += 1 except Exception as e: errors.append(repr(e)); stop.set() def rollback_worker(): rpc = get_rpc_proxy(node.url, 0, timeout=30) while not stop.is_set(): try: tip = rpc.getbestblockhash() rpc.invalidateblock(tip); rpc.reconsiderblock(tip) counts["rollbacks"] += 1 except Exception as e: errors.append(repr(e)); stop.set() threads = [threading.Thread(target=dkg_worker) for _ in range(6)] + [threading.Thread(target=rollback_worker)] start = time.time() for t in threads: t.start() while not stop.is_set() and time.time() - start < DURATION and node.process.poll() is None: time.sleep(0.2) stop.set() for t in threads: t.join() self.log.info("ran %.1fs: %d dkgstatus calls, %d invalidate/reconsider rounds", time.time() - start, counts["dkgstatus"], counts["rollbacks"]) # (the full script also reports dashd's exit code and stderr, then fails if dashd exited) ... if __name__ == "__main__": DkgStatusRollbackRace().main() ``` Unfixed (`c14104b172a2`): ``` $ DASH_WORKTREE=$PWD REPRO_SECONDS=120 python3 repro_dkgstatus_rollback.py --configfile=test/config.ini --portseed=3303 TestFramework (INFO): tip height 200, enabled dkgstatus types: 4 TestFramework (INFO): ran 0.2s: 177 dkgstatus calls, 8 invalidate/reconsider rounds TestFramework (ERROR): RESULT: dashd EXITED with code -6 after 0.2s TestFramework (ERROR): dashd stderr: Assertion failure: TestFramework (ERROR): dashd stderr: assertion: nHeight <= active_chain.Height() + 1 TestFramework (ERROR): dashd stderr: Assertion failed: (nHeight <= active_chain.Height() + 1), function IsMiningPhase, file blockprocessor.cpp, line 317.

If a poll happens to overlap a tip disconnect, the node aborts. A crashed masternode can then collect PoSe penalties. The trigger needs RPC access plus a rollback at the wrong moment, so this is a local reliability bug, not something a remote peer can trigger on demand. Funds and consensus are not affected. ## What was done? Two changes in `quorum_dkgstatus` in `src/rpc/quorums.cpp`: - The height passed to `GetMineableCommitments` is now `chainman.ActiveChain().Height() + 1`, read inside the same `LOCK(cs_main)` as the call. This keeps the "next block after the tip" meaning from dashpay#7770 and guarantees `nHeight <= Height() + 1` when `IsMiningPhase` checks it. - The quorum base block is now found with `pindexTip->GetAncestor(quorumHeight)` instead of `ActiveChain()[quorumHeight]`. Since `quorumHeight <= tipHeight`, this never returns `nullptr`. It also matches the tip the rest of the loop already uses for `GetEnabledQuorumTypes` / `IsQuorumRotationEnabled`, and it removes one `cs_main` acquisition. ### Why this is the correct minimal fix The root cause is that the RPC mixes a height read under one `cs_main` scope with a chain read under another. Both changes make each lookup consistent with the chain state it is checked against, and nothing else changes. Holding `cs_main` across the whole RPC would also work, but `GetQuorumConnections` and `connman.ForEachNode` run in that loop, and holding the lock across them is unnecessary. Clamping or skipping in the RPC would leave the stale height in place. The asserts in `IsMiningPhase` / `GetNumCommitmentsRequired` / `GetMineableCommitments` are deliberately left alone: they protect block creation and validation, where the height always comes from the chain under the same lock. Output is unchanged when the chain does not move during the call. If the chain grows during the call, `minableCommitments` now describes the block after the current tip instead of the one after the earlier sample. That is what the field is documented to mean. This fixes a regression from dashpay#7770, which shipped in v24.0.0-rc.2, so it should also go to the v24.0.x branch before the final release. ## How Has This Been Tested? macOS arm64, debug build (`--enable-debug`, assertions on). - Ran the reproduction script above against unfixed `c14104b172a2`: dashd aborted on the `IsMiningPhase` assert within 0.2 s in 4 of 4 runs. - Ran the same script with this PR: 120 s, 816,452 calls, 44,361 rollbacks, no abort. A second 30 s run after clang-format: 208,389 calls, 11,386 rollbacks, no abort. - `test/functional/test_runner.py feature_llmq_simplepose.py feature_llmq_rotation.py feature_llmq_connections.py`: all passed, including `feature_llmq_simplepose.py --disable-spork23`. These tests call `quorum dkgstatus` on masternodes through the framework's quorum-connection and probe helpers, so they exercise the `GetAncestor` path and the `minableCommitments` path. - `clang-format-diff.py` on the change is clean. No regression test is added. The bug is a race between two RPC threads, and catching it needs a multi-threaded stress loop. Such a test can only show the bug on a lucky interleaving, and it would add run time to the suite for a two-line change. The script above is how the fix was verified. ## Breaking Changes None. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

…ead of aborting at startup cdeadac fix(qt): report malformed lang/font settings instead of aborting at startup (pasta) Pull request description: ## Issue being fixed or feature implemented If `settings.json` contains a `"lang"`, `"font-family"`, `"font-scale"`, `"font-weight-normal"` or `"font-weight-bold"` value of an unexpected JSON type (an object or an array, e.g. after a hand edit or a bad merge of the file), dash-qt is terminated at startup by an uncaught exception (`std::terminate`, exit 134). It should instead show the existing "Could not read setting ... Settings file ... might be corrupt or invalid." error, which is what already happens for the same mistake in `prune`, `proxy`, `onion`, `dbcache` and the other settings handled by the `getOption()` loop in `OptionsModel::Init`. The conversion helpers (`SettingToString` / `SettingToInt`) fall back to `UniValue::get_str()` for anything that is not null, a bool or a number, so an object or array throws `UniValue::type_error`. `OptionsModel::Init` already catches that for the settings read in its `getOption()` loop (added with bitcoin-core/gui#602), but a few reads happen outside that loop: - `"lang"`, read at the top of `OptionsModel::Init` (same as upstream), and also read earlier through `gArgs.GetArg("-lang")` in `GetLangTerritory()`, which is called again right after `common::InitConfig` has loaded `settings.json`. - The Dash font settings (`font-family`, `font-scale`, `font-weight-normal`, `font-weight-bold`), read before the loop once fonts are loaded. - When `-font-family` is given on the command line and the weight is not, `Init` does not read the stored `font-weight-normal` / `font-weight-bold` at all. A malformed weight then gets through `Init`, and `GuiMain` throws on it a moment later from `gArgs.IsArgSet("-font-weight-normal")` / `gArgs.GetIntArg(...)`, which also see `settings.json`. None of these call sites is inside a `try` block. The only `catch` in `GuiMain` starts after the options model has been created, so the exception ends in `std::terminate`. ### Why this is a real problem Code path at c14104b: - `SettingToString` / `SettingToInt` fall back to `get_str()`: [src/util/system.cpp#L529-L536](https://github.com/dashpay/dash/blob/c14104b172a2/src/util/system.cpp#L529-L536), [#L554-L561](https://github.com/dashpay/dash/blob/c14104b172a2/src/util/system.cpp#L554-L561) - Unprotected `"lang"` read: [src/qt/optionsmodel.cpp#L208](https://github.com/dashpay/dash/blob/c14104b172a2/src/qt/optionsmodel.cpp#L208) - Unprotected font reads: [src/qt/optionsmodel.cpp#L258-L302](https://github.com/dashpay/dash/blob/c14104b172a2/src/qt/optionsmodel.cpp#L258-L302); the stored weights are skipped when only `-font-family` is overridden: [#L281-L282](https://github.com/dashpay/dash/blob/c14104b172a2/src/qt/optionsmodel.cpp#L281-L282), [#L297-L298](https://github.com/dashpay/dash/blob/c14104b172a2/src/qt/optionsmodel.cpp#L297-L298) - `GuiMain` reading the weights through `gArgs` after `Init`: [src/qt/bitcoin.cpp#L700-L701](https://github.com/dashpay/dash/blob/c14104b172a2/src/qt/bitcoin.cpp#L700-L701), [#L709-L710](https://github.com/dashpay/dash/blob/c14104b172a2/src/qt/bitcoin.cpp#L709-L710) - The loop that does handle type errors: [src/qt/optionsmodel.cpp#L355-L370](https://github.com/dashpay/dash/blob/c14104b172a2/src/qt/optionsmodel.cpp#L355-L370) - `GetLangTerritory()` reading `-lang` through `gArgs`: [src/qt/bitcoin.cpp#L122](https://github.com/dashpay/dash/blob/c14104b172a2/src/qt/bitcoin.cpp#L122), called again after `InitConfig` at [#L621](https://github.com/dashpay/dash/blob/c14104b172a2/src/qt/bitcoin.cpp#L621) / [#L644](https://github.com/dashpay/dash/blob/c14104b172a2/src/qt/bitcoin.cpp#L644) - `createOptionsModel` only handles a `false` return, not an exception: [src/qt/bitcoin.cpp#L248-L265](https://github.com/dashpay/dash/blob/c14104b172a2/src/qt/bitcoin.cpp#L248-L265), called at [#L687](https://github.com/dashpay/dash/blob/c14104b172a2/src/qt/bitcoin.cpp#L687), before the `try` at [#L777](https://github.com/dashpay/dash/blob/c14104b172a2/src/qt/bitcoin.cpp#L777) Reproduction with dash-qt built from unmodified c14104b (macOS, `--with-gui`, debug build): <details> <summary>dash-qt with <code>{"lang": {}}</code> in settings.json (unfixed)</summary> ``` $ cat $DATADIR/regtest/settings.json {"lang": {}} $ timeout 60 src/qt/dash-qt -regtest -datadir=$DATADIR -nosplash std::terminate() called due to unhandled exception Exception: type=UniValue::type_error, what="JSON value of type object is not of expected type string" exit status: 134 ``` No `debug.log` is created: the abort happens in the second `initTranslations()` call, before the node is created. </details> <details> <summary>dash-qt with <code>{"font-weight-normal": []}</code> in settings.json and <code>-font-family</code> on the command line (unfixed)</summary> ``` $ cat $DATADIR/regtest/settings.json {"font-weight-normal": []} $ timeout 20 src/qt/dash-qt -regtest -datadir=$DATADIR -nosplash -font-family=Montserrat std::terminate() called due to unhandled exception Exception: type=UniValue::type_error, what="JSON value of type array is not of expected type string" exit status: 134 ``` </details> The new `OptionTests` cases, run against the unfixed `OptionsModel::Init`: <details> <summary>test_dash-qt (unfixed), default <code>minimal</code> platform</summary> ``` $ src/qt/test/test_dash-qt ********* Start testing of OptionTests ********* PASS : OptionTests::initTestCase() PASS : OptionTests::migrateSettings() PASS : OptionTests::integerGetArgBug() SKIP : OptionTests::invalidFontSetting() AppTests cannot initialize fonts with the 'minimal' platform plugin.

The way out (start with `-nosettings` or fix `settings.json` by hand) is not discoverable from an abort. It only affects startup of dash-qt with a malformed local `settings.json`; dashd is not affected and nothing reaches this path from the network. ## What was done? - `OptionsModel::Init`: the `"lang"` read and the four font reads are wrapped in `try`/`catch` and report the error the same way as the existing `getOption()` loop. The error formatting is moved into a small local lambda (`setting_error`) so the loop and the new call sites share one message; the translatable string is unchanged. - `OptionsModel::Init`: the stored font weights are now always read (and so checked), and the existing condition then picks either that value or the font's default weight as before. This closes the `-font-family` path above. - `GetLangTerritory()`: if reading `-lang` throws, keep the language picked from QSettings / the system locale. Startup then continues to `OptionsModel::Init`, which reports the bad `"lang"` value through the normal error dialog. - `OptionTests`: `invalidLangSetting` and `invalidFontSetting` put an object/array into the persistent settings and check that `Init` returns `false` with the expected error. `invalidFontSetting` also covers the weights with `-font-family` set on the command line. The font case needs loaded fonts, so like `updateFontsWithPixelSizedWidget` it is skipped on the `minimal` platform. ### Why this is the correct minimal fix The root cause is that these reads sit outside the error handling that bitcoin-core/gui#602 added for exactly this kind of type error, so the fix puts them under the same handling and reuses the same message. For the font weights only the `SettingToInt` read is inside the `try`. The font settings are not simply added to the `getOption()` loop: that loop also calls `addOverriddenOption()`, which the font blocks already do, so the overridden-options list would get duplicate entries. Reading the stored weights unconditionally does not change which weight is applied; it only makes sure that a value `GuiMain` will read through `gArgs` anyway has been checked first. Fixing only `OptionsModel::Init` is not enough for `"lang"`: `GetLangTerritory()` reads the same value first and would still abort before `Init` runs. A type check there would need to duplicate which `UniValue` types `SettingToString` accepts, while catching the conversion error keeps the existing `-lang` behaviour (strings, `-nolang`, numbers) unchanged. Making the conversion helpers non-throwing or widening `GuiMain`'s `try` would be larger changes; the latter would also only swap the abort for a generic "runaway exception" message. Behaviour for valid settings is unchanged. If the bold weight is malformed after the normal weight has been reset via `forceSetting`, that partial state is not undone; `Init` returns `false` and startup stops anyway. The `"lang"` handling exists the same way in Bitcoin Core and could also be sent upstream. ## How Has This Been Tested? macOS arm64, `--with-gui --enable-debug --enable-werror`, depends Qt 5. - Before the fix: the two dash-qt reproductions and the two `test_dash-qt` runs above (abort, exit 134). - With the `try`/`catch` changes but without always reading the stored weights, the `-font-family` cases of `invalidFontSetting` fail (cocoa): ``` FAIL! : OptionTests::invalidFontSetting() '!OptionsModel{m_node}.Init(error)' returned FALSE. () Loc: [qt/test/optiontests.cpp(135)] ``` - After the fix, `src/qt/test/test_dash-qt` (default `minimal` platform): all suites pass; in `OptionTests`, `invalidLangSetting` passes and `invalidFontSetting` is skipped as expected. ``` SKIP : OptionTests::invalidFontSetting() AppTests cannot initialize fonts with the 'minimal' platform plugin. PASS : OptionTests::invalidLangSetting() ... Totals: 8 passed, 0 failed, 2 skipped, 0 blacklisted, 11ms ``` - After the fix, `QT_QPA_PLATFORM=cocoa src/qt/test/test_dash-qt`: all `OptionTests` pass, including both new cases. ``` PASS : OptionTests::invalidFontSetting() PASS : OptionTests::invalidLangSetting() ... Totals: 10 passed, 0 failed, 0 skipped, 0 blacklisted, 15ms ``` - After the fix, dash-qt with `{"lang": {}}`: no abort; it reports the error and shows the dialog (the process was then killed by `timeout` while the modal dialog was open): ``` $ timeout 20 src/qt/dash-qt -regtest -datadir=$DATADIR -nosplash Error: Could not read setting "lang", JSON value of type object is not of expected type string. Settings file "<datadir>/regtest/settings.json" might be corrupt or invalid. exit status: 124 ``` - After the fix, dash-qt with `{"font-weight-normal": []}` and `-font-family=Montserrat`: same, no abort: ``` $ timeout 20 src/qt/dash-qt -regtest -datadir=$DATADIR -nosplash -font-family=Montserrat Error: Could not read setting "font-weight-normal", JSON value of type array is not of expected type string. Settings file "<datadir>/regtest/settings.json" might be corrupt or invalid. exit status: 124 ``` - `contrib/devtools/clang-format-diff.py` only suggests reflowing the moved `tr()` line and the test lambdas/strings, which follow the style of the surrounding code; `test/lint/lint-whitespace.py` is clean. ## Breaking Changes None. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

For an evonode on legacy (pre-extended) addresses, the full masternode state (`protx info`, `protx list`, `addedMNs` in `protx listdiff`, ...) reports `addresses.platform_p2p` / `addresses.platform_https` as the core P2P address paired with the legacy `platformP2PPort` / `platformHTTPPort` (`GetNetInfoWithLegacyFields()`). The state diffs in `protx listdiff`'s `updatedMNs` only reported them when the ports themselves changed. A diff that changed only the core P2P address carried `core_p2p` alone. So a client that follows `protx listdiff` and reads only `addresses` never learns the Platform ports of a legacy evonode that it first saw without an address, if the evonode later gets an address with unchanged ports. An evonode has no address when it is registered without one (allowed; it starts PoSe-banned) or after its operator fields are reset (revocation or operator key change), and a ProUpServTx later revives it, typically with the same ports. This happened on testnet: evonode `b2626fdf98bc671ccf7711bb2dacaed615b98c4092f527a0bacd1519a408c2ae` was registered at 1394574, had its operator key changed at 1394576 and was revived at 1394577 with ports 36656/1443 unchanged. Its ports were then only visible through the deprecated fields. Extended-address evonodes don't have this problem, since their diffs carry the whole netInfo object, Platform entries included. ### Why Dash Platform needs this Dash Platform's Drive follows `protx listdiff` to maintain its masternode list and build its validator sets, and validator-set membership is consensus-relevant for Platform. Drive currently reads the flat `platformP2PPort` / `platformHTTPPort`, so every Platform node has to run Core with `-deprecatedrpc=service`. To read only `addresses` and drop that flag, Drive must be able to learn every evonode's Platform ports from `addresses`, which it can't in the case above. `protx listdiff` is computed from stored states when it is called, so with this change historical windows are covered as well. ## What was done? The change is confined to `protx listdiff` in `src/rpc/evo.cpp`: - Each updated masternode is looked up in the target list instead of the base list. `updatedMNs` is keyed by the target entry's internal id, and `proTxHash` and type are the same in both lists; the target entry gives the masternode's state at the diff's target block. - When a diff changes the masternode's address and the new address is not empty, `addresses` in the diff output is replaced with `GetNetInfoWithLegacyFields()` of the target state. This is the helper the full-state outputs use, so the diff reports exactly what the full state does. For regular masternodes and extended-address evonodes the helper returns what the diff already reported, so only legacy evonodes see a difference. `CDeterministicMNStateDiff::ToJson()` and `evo/dmnstate.*` are not changed. The target state is only known to the RPC, and `GetNetInfoWithLegacyFields()` lives outside `libdashkernel`, so the completion is done in the RPC layer. Unchanged, on purpose: - A diff that changes only the Platform ports still pairs them with the `255.255.255.255` placeholder, as documented in the 23.0 release notes. - A diff that clears a masternode's address still omits `addresses`. If the ports change in the same diff window, they are still reported as `[::]:<port>`. - `protx diff`, the full-state outputs and what `-deprecatedrpc=service` gates are unchanged. There are no consensus, serialization, evodb or P2P changes. ## How Has This Been Tested? `rpc_netinfo.py`, in the existing `test_deprecation()` step (legacy evonode, queried on a node without `-deprecatedrpc=service`): - Address-only diff: the first and the third ProUpServTx of that step set the same Platform ports, so `protx listdiff` between their heights changes only the core P2P address. The test checks that its `addresses` holds `core_p2p`, `platform_p2p` and `platform_https` on the new address with the unchanged ports. This is the case being fixed. - Cleared address: the operator is revoked, which clears the address and keeps the legacy ports. The test checks that the full state's `addresses` is empty and that the diff has no `addresses` key. Already covered by existing assertions: - `test_deprecation()`: a legacy evonode whose address and ports change together, and the placeholder for a port-only change. - `test_shims()`: the exact `addresses` of an extended-address evonode's diff. ## Breaking Changes `protx listdiff`: for an evonode on legacy addresses, an `updatedMNs` entry whose diff changes the core P2P address now includes `platform_p2p` and `platform_https` in `addresses`, where it previously carried `core_p2p` alone. Both keys were already possible there, with the same format. ## Checklist: - [x] I have performed a self-review of my own code - [x] I have made corresponding changes to the documentation - [x] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) ACKs for top commit: knst: self-ACK 18c08a6 kwvg: utACK 18c08a6 Tree-SHA512: 9e9007b75aed678112026d8a0b1257c136294fff7973816cc9f5ce58b4e72f21d580e629ab86da16acd061ae98a346740325c31d25b8bfa326ca8b33dffa9ada (cherry picked from commit 0021b20)

…ass PSBT by const reference in PSBTInputSignedAndVerified) 4b94367 partial Merge bitcoin#31650: refactor: Avoid copies by using const references or by move-construction (pasta) 2cb6f5a Merge bitcoin#34272: psbt: Fix `PSBTInputSignedAndVerified` bounds `assert` (pasta) Pull request description: ## Issue being fixed or feature implemented `PSBTInputSignedAndVerified()` takes its `PartiallySignedTransaction` by value (`const PartiallySignedTransaction psbt`, missing the `&`). Each call therefore copies the whole PSBT: the unsigned transaction with all its inputs and outputs, and every `PSBTInput`/`PSBTOutput` with its scripts, keypath maps and unknown fields. The function is called once per input. `SignPSBTInput()` calls it first thing, `FinalizePSBT()` calls `SignPSBTInput()` for every input, and `AnalyzePSBT()` calls it directly and then again through `SignPSBTInput()`. So `finalizepsbt`, `analyzepsbt`, `walletprocesspsbt` and the other PSBT paths do work proportional to (number of inputs) × (PSBT size), which is quadratic in the input count. The copy happens before any check, so inputs with no UTXO data pay for it too. This came in with the partial backport of bitcoin#25595 (2aa0e7b), so it affects the v24.0.0 release candidates. v23.2 used `PSBTInputSigned(const PSBTInput&)` on these paths and was linear. Upstream fixed the signature in bitcoin#31650. The same function also has an off-by-one debug assertion, `assert(psbt.inputs.size() >= input_index)`, which accepts `input_index == psbt.inputs.size()` even though the next line indexes `psbt.inputs[input_index]`. Upstream fixed this in bitcoin#34272. No current caller passes an out-of-range index: every caller loops over `i < tx->vin.size()`, and decoding requires `inputs.size() == vin.size()`. So this part only restores the intended guard. ### Why this is a real problem Code path at c14104b: - By-value declaration and definition: [src/psbt.h#L872](https://github.com/dashpay/dash/blob/c14104b172a2/src/psbt.h#L872), [src/psbt.cpp#L184-L187](https://github.com/dashpay/dash/blob/c14104b172a2/src/psbt.cpp#L184-L187) - Called unconditionally from `SignPSBTInput()`: [src/psbt.cpp#L269](https://github.com/dashpay/dash/blob/c14104b172a2/src/psbt.cpp#L269) - `FinalizePSBT()` calls `SignPSBTInput()` once per input: [src/psbt.cpp#L333](https://github.com/dashpay/dash/blob/c14104b172a2/src/psbt.cpp#L333) - `AnalyzePSBT()` makes two calls per non-final input: [src/node/psbt.cpp#L61](https://github.com/dashpay/dash/blob/c14104b172a2/src/node/psbt.cpp#L61), [src/node/psbt.cpp#L66](https://github.com/dashpay/dash/blob/c14104b172a2/src/node/psbt.cpp#L66) Measured on regtest with a functional-test-style script. It builds a PSBT with N inputs using `createpsbt` (inputs without UTXO data, one `data` output), then times one `finalizepsbt` and one `analyzepsbt` call. Both builds use the same configuration (`--enable-debug`, so absolute times are higher than in a release build; the growth ratio is the point). <details><summary>Script</summary> ```python class PSBTCopyScaling(BitcoinTestFramework): def set_test_params(self): self.num_nodes = 1 self.setup_clean_chain = True self.rpc_timeout = 600 def run_test(self): node = self.nodes[0] for n in (2000, 4000, 8000, 16000): inputs = [{"txid": "%064x" % (i + 1), "vout": 0} for i in range(n)] psbt = node.createpsbt(inputs, [{"data": "00"}]) t0 = time.perf_counter(); res = node.finalizepsbt(psbt); t_fin = time.perf_counter() - t0 assert not res["complete"] t0 = time.perf_counter(); res = node.analyzepsbt(psbt); t_ana = time.perf_counter() - t0 assert len(res["inputs"]) == n self.log.info(...) ``` </details> <details><summary>Unfixed (c14104b): each doubling of the input count costs 4x</summary> ``` TestFramework (INFO): inputs= 2000 psbt_bytes= 84039 finalizepsbt= 0.092s analyzepsbt= 0.183s TestFramework (INFO): inputs= 4000 psbt_bytes= 168039 finalizepsbt= 0.361s analyzepsbt= 0.730s (x3.9 / x4.0 vs previous) TestFramework (INFO): inputs= 8000 psbt_bytes= 336039 finalizepsbt= 1.436s analyzepsbt= 2.862s (x4.0 / x3.9 vs previous) TestFramework (INFO): inputs= 16000 psbt_bytes= 672039 finalizepsbt= 5.735s analyzepsbt= 11.462s (x4.0 / x4.0 vs previous) ``` </details> <details><summary>With this PR: linear, over 250x faster at 16000 inputs</summary> ``` TestFramework (INFO): inputs= 2000 psbt_bytes= 84039 finalizepsbt= 0.016s analyzepsbt= 0.008s TestFramework (INFO): inputs= 4000 psbt_bytes= 168039 finalizepsbt= 0.016s analyzepsbt= 0.012s (x1.0 / x1.5 vs previous) TestFramework (INFO): inputs= 8000 psbt_bytes= 336039 finalizepsbt= 0.014s analyzepsbt= 0.021s (x0.9 / x1.8 vs previous) TestFramework (INFO): inputs= 16000 psbt_bytes= 672039 finalizepsbt= 0.021s analyzepsbt= 0.040s (x1.6 / x1.9 vs previous) ``` </details> ### Why it matters A PSBT with several thousand inputs (for example, a large consolidation) makes `analyzepsbt`/`finalizepsbt` take seconds instead of milliseconds. A 670 kB PSBT already ties up an RPC worker thread for over 11 seconds, and the cost keeps growing quadratically with larger PSBTs. Only the RPC interface and local tooling reach these paths, so the impact is wasted CPU and allocation work plus slow RPC responses. There is no network-facing or consensus effect. ## What was done? Two backport commits: - bitcoin#34272 (full, 2f5b1c5): changes the bounds assertion in `PSBTInputSignedAndVerified()` to `assert(input_index < psbt.inputs.size())`. - bitcoin#31650 (partial): only the `src/psbt.{h,cpp}` hunk of faf0c2d, which changes the parameter to `const PartiallySignedTransaction& psbt`. Omitted from bitcoin#31650: - The rest of faf0c2d: `src/external_signer.{h,cpp}` (move-construct the `ExternalSigner` strings, `const std::string&` chain in `Enumerate`), `src/netbase.h` (move-construct the `Proxy` unix socket path), `src/test/argsman_tests.cpp`, `src/wallet/rpc/util.{h,cpp}` (`HandleWalletError` takes `const std::shared_ptr<CWallet>&`) and `src/wallet/wallet.{h,cpp}` (`GetNewDestination` label by `const std::string&`). These are small copy cleanups unrelated to PSBT handling. They can come with a full backport of the PR. - All of fa64d84 (enable clang-tidy `readability-avoid-const-params-in-decls`). It needs a tree-wide sweep of Dash-specific declarations first. ### Why this is the correct minimal fix The function only reads the PSBT, and no caller relies on getting a private copy. `SignPSBTInput()` mutates its own `psbt` only after the helper returns. Passing by const reference removes the per-call copy and so removes the quadratic term, without changing any result. This is exactly the upstream change. Smaller alternatives do not exist, and restructuring the callers is unnecessary. The assertion change follows upstream bitcoin#34272, which was raised in review of bitcoin#31650. It touches the same function and makes the existing guard match the index it protects. Behavior for all valid inputs is unchanged. This should also go to the v24.0.x release branch: the by-value copy is new in the v24.0.0 release candidates (v23.2 was linear on these paths). ## How Has This Been Tested? - Built `dashd`, `dash-cli` and `test_dash` (macOS arm64, depends prefix, `--enable-debug --enable-werror --without-gui`) before and after the change. - Ran the scaling script above against both builds (output shown above): quadratic before, linear after. - `src/test/test_dash --run_test=psbt_wallet_tests`: no errors. - `test/functional/test_runner.py rpc_psbt.py`: `--descriptors` and `--legacy-wallet` both passed. - `test/lint/lint-whitespace.py`: clean. No regression test was added. The change is a missing `&` and an assertion bound that no caller can reach, and the effect is purely on performance, which cannot be asserted deterministically in the test suite.

…ed dash-cli command 5339d4f refactor(contrib): match dash-cli connection options by prefix in fish completion (pasta) ff98899 fix(contrib): stop fish completion from re-running the typed dash-cli command (pasta) Pull request description: ## Issue being fixed or feature implemented The fish completion for `dash-cli` (`contrib/completions/fish/dash-cli.fish`, imported from bitcoin#24611) builds its suggestions by running the command line the user has typed so far, with `help` or `-help` appended. Once an RPC command has been typed, everything after it is passed to the node as RPC parameters, so the appended `help` does not ask for help: it becomes one more parameter of the typed command, and the command runs. For anyone who has installed this completion, pressing Tab after a complete line such as `dash-cli sendtoaddress <address> 1 ` sends the coins before Enter is pressed, with `help` as the wallet comment. Each Tab runs the line several times, because every `complete` rule's `--condition` calls the helper again. Pressing Enter afterwards sends once more. The same applies to any RPC that accepts a trailing string parameter. A leading `-generate` reserves a new wallet address on each Tab. ### Why this is a real problem Code path at c14104b: - [`dash-cli.fish#L5`](https://github.com/dashpay/dash/blob/c14104b172a2/contrib/completions/fish/dash-cli.fish#L5) takes every completed token with `commandline -oc`. [L13-L16](https://github.com/dashpay/dash/blob/c14104b172a2/contrib/completions/fish/dash-cli.fish#L13-L16) strip only a bare `help` and `-stdin*`, and [L19](https://github.com/dashpay/dash/blob/c14104b172a2/contrib/completions/fish/dash-cli.fish#L19) runs `$cmd help`. [L63](https://github.com/dashpay/dash/blob/c14104b172a2/contrib/completions/fish/dash-cli.fish#L63) and [L65](https://github.com/dashpay/dash/blob/c14104b172a2/contrib/completions/fish/dash-cli.fish#L65) run `$cmd -help` the same way. - All three rules ([L75-L99](https://github.com/dashpay/dash/blob/c14104b172a2/contrib/completions/fish/dash-cli.fish#L75-L99)) call the helper from `--condition`, which fish evaluates on every Tab. - [`src/util/system.cpp#L262-L276`](https://github.com/dashpay/dash/blob/c14104b172a2/src/util/system.cpp#L262-L276): the first non-dash argument is the command. All later argv entries, including `help` and `-help`, are copied into the command arguments without being parsed. [`src/bitcoin-cli.cpp#L1207-L1212`](https://github.com/dashpay/dash/blob/c14104b172a2/src/bitcoin-cli.cpp#L1207-L1212) sends `args[0]` as the method. - [`src/wallet/rpc/spend.cpp#L238`](https://github.com/dashpay/dash/blob/c14104b172a2/src/wallet/rpc/spend.cpp#L238): the third `sendtoaddress` parameter is an optional string `comment`, so `help` is accepted and the send goes ahead. Reproduction against the unfixed tree. A fresh regtest `dashd` is built from this branch, wallet `w1` is funded, and `w2` provides the destination address. One Tab is simulated with fish 4.9.3 `complete -C '<line>'`, which evaluates the completion rules exactly as an interactive Tab does. Enter is never pressed.

With this completion installed, Tab can broadcast a payment the user has not confirmed. It does so several times per keypress, so a later Enter produces a duplicate payment. Any other state-changing RPC that tolerates the extra parameter runs early in the same way. The scope is limited: the completion is opt-in and not installed by the build, it needs working RPC credentials and an unlocked wallet, and the user must already have typed the full command. Nothing is reachable remotely. The effect is still an unintended spend of the user's own funds. ## What was done? Only `contrib/completions/fish/dash-cli.fish` changes. The first commit is the fix; the second replaces the explicit option list with prefix matching. - `__fish_dash_cli_get_commands_helper` now runs `help` with only the executable and the connection options typed before the RPC command, matched by prefix: `-conf`, `-datadir`, `-testnet`, `-regtest`, `-devnet`, `-chain`, and every `-rpc*` option except `-rpcwait*` (which would make Tab hang while the node is down). This is the same prefix approach as the dash-cli bash completion, so new `-rpc*` connection options need no edits here. It stops at the first non-dash token, so the RPC command and its arguments are never passed on. Other leading options are dropped, including `-generate`, `-getinfo`, `-netinfo`, `-addrinfo`, `-named`, `-rpcwait*` and `-stdin*`. This replaces the old ad hoc stripping of `help` and `-stdin*`, which the allowlist covers. - `__fish_dash_cli_get_options` runs `-help` on the bare executable (`$cmd[1]`). The option list does not depend on the rest of the line, and the other Dash completion scripts (`dash-tx.fish`, `dash-wallet.fish`, `dash-util.fish`, `dashd.fish`) already do this. ### Why this is the correct minimal fix The root cause is that the completion re-executes user input. The fix stops passing that input on, and keeps only what is needed to reach the same node and wallet (datadir, conf, network, RPC endpoint and credentials, wallet). An allowlist is used because a denylist would have to keep up with every dash-cli option that changes what gets executed. Some leading options are themselves commands: `-generate` calls `getnewaddress` before it validates its arguments. Stripping only `help` would not help, because any typed RPC still runs. Excluding specific RPCs would always miss some. Left unchanged on purpose: the completion rules, the output parsing, and the `-help`/`-?` early returns. The helper is still called once per rule on each Tab, which now only issues the read-only `help` RPC. Caching it, or adding a default client timeout, would be separate improvements. Bitcoin Core's `bitcoin-cli.fish` has the same pattern. ## How Has This Been Tested? No automated test was added. The repository has no harness for shell completion scripts, and the behaviour was checked end to end against a real node instead. Environment: macOS arm64, `dashd`/`dash-cli` built from this branch, fish 4.9.3. - `regtest-repro.sh` before the fix: one Tab after `sendtoaddress <w2 address> 1 ` produced 5 sends from `w1` (5 DASH received by `w2`, 5 transactions in the mempool, comments `help` ×3 and `-help` ×2). The `-generate ` Tab reduced the keypool from 1000 to 999. Output is above. - `regtest-repro.sh` after the fix: no sends, `w2` balance 0, empty mempool, keypool unchanged. Command, `help <command>` and option completion return the same suggestions as before. <details><summary>Fixed: same script</summary> ``` $ git diff --stat contrib/completions/fish/dash-cli.fish | 21 +++++++++++++-------- 1 file changed, 13 insertions(+), 8 deletions(-) $ regtest-repro.sh $PWD == completion output == Tab after 'dash-cli -regtest -datadir=DATADIR -rpcport=19876 getblockc': getblockchaininfo getblockcount Tab after 'dash-cli -regtest -datadir=DATADIR -rpcport=19876 -rpcwallet=w1 sendtoa': sendtoaddress "address" amount ( "comment" "comment_to" subt Tab after 'dash-cli -regtest -datadir=DATADIR -rpcport=19876 -rpcwallet=w1 -rpcw': -rpcwait -rpcwaittimeout= -rpcwallet= Tab after 'dash-cli -regtest -datadir=DATADIR -rpcport=19876 help getblockc': getblockchaininfo getblockcount == sendtoaddress == w1 txs before Tab: 0 sends w2 balance before Tab (minconf 0): 0.00000000 $ fish -c "source dash-cli.fish; complete -C 'dash-cli -regtest -datadir=DATADIR -rpcport=19876 -rpcwallet=w1 sendtoaddress ya4Gcphm7nFvTRuHjLqnmqh6W6tkhjmvfL 1 '" # one Tab press, Enter never pressed w1 txs after Tab: 0 sends w2 balance after Tab (minconf 0): 0.00000000 mempool size: "size": 0, comments on the w1 sends: == -generate == w1 before Tab: "keypoolsize": 1000,, blocks: 110 $ fish -c "source dash-cli.fish; complete -C 'dash-cli -regtest -datadir=DATADIR -rpcport=19876 -rpcwallet=w1 -generate '" # one Tab press, Enter never pressed w1 after Tab: "keypoolsize": 1000,, blocks: 110 ``` </details> <details><summary>Fixed: commands run by the completion for one Tab (logging stand-in)</summary> ``` $ git diff --stat contrib/completions/fish/dash-cli.fish | 21 +++++++++++++-------- 1 file changed, 13 insertions(+), 8 deletions(-) $ stub-repro.sh $PWD ### Tab after: 'dash-cli -regtest ' ran: dash-cli -regtest help ran: dash-cli -regtest help ran: dash-cli -regtest help ran: dash-cli -help ran: dash-cli -help ### Tab after: 'dash-cli -regtest -rpcwallet=w1 sendtoaddress yNmxLr8sgqWjj8qEcvH7bD3b4G4Bu4PZpq 1 ' ran: dash-cli -regtest -rpcwallet=w1 help ran: dash-cli -regtest -rpcwallet=w1 help ### Tab after: 'dash-cli -regtest -generate ' ran: dash-cli -regtest help ran: dash-cli -regtest help ran: dash-cli -regtest help ran: dash-cli -help ran: dash-cli -help ### Tab after: 'dash-cli -regtest -stdin ' ran: dash-cli -regtest help ran: dash-cli -regtest help ran: dash-cli -regtest help ran: dash-cli -help ran: dash-cli -help ``` </details> - After switching to prefix matching (second commit), the regtest check was repeated: command, `help <command>`, option and `-rpcwait` line completions return the expected suggestions; Tab after the `sendtoaddress` line and after `-generate ` leaves w1 with 0 sends, keypool 1000 and an empty mempool; with the node stopped, Tab after `-rpcwait getblockc` returns immediately.

… so rebalancing cannot oscillate 076b093 fix(coinjoin): floor the denomination gap threshold so rebalancing cannot oscillate (pasta) Pull request description: ## Issue being fixed or feature implemented CoinJoin promotion and demotion use a gap threshold so that converting coins between two adjacent denominations does not flip back and forth. Since the threshold was scaled with the goal (`GetGapThreshold(nGoal) = max(nGoal / 5, 1)`), any `-coinjoindenomsgoal` below 25 gets a gap of 4 or less. That is too small to absorb the 10:1 asymmetry of a conversion: a promotion moves the smaller denomination's deficit by up to +10 and the larger one's by -1, so with a gap of `g` an immediate reversal is possible whenever `2g + 1 <= PROMOTION_RATIO`, i.e. `g <= 4`. Example at the minimum goal of 10 (gap 2), all coins fully mixed: - 10 smaller / 7 larger: deficits 0 vs 3, `3 > 0 + 2`, so the wallet promotes. - Result 0 smaller / 8 larger: deficits 10 vs 2, `10 > 2 + 2`, so the wallet demotes back to 10 / 7. - Once the 10 demoted outputs are mixed again, the promotion fires again, and so on. Only wallets that set the goal below 25 are affected; the default of 50 (gap 10) is not. ### Why this is a real problem The decision functions fire on a one-sided deficit comparison with no other hysteresis: - [`GetGapThreshold`](https://github.com/dashpay/dash/blob/c14104b172a2/src/coinjoin/common.h#L131) - [`ShouldPromoteDenoms`](https://github.com/dashpay/dash/blob/c14104b172a2/src/coinjoin/common.h#L224-L233) and [`ShouldDemoteDenoms`](https://github.com/dashpay/dash/blob/c14104b172a2/src/coinjoin/common.h#L242-L251) - The client passes wallet totals and `GetDenomsGoal()` straight through ([client.cpp](https://github.com/dashpay/dash/blob/c14104b172a2/src/coinjoin/client.cpp#L2494-L2520)), and the goal can be set as low as [`MIN_COINJOIN_DENOMS_GOAL = 10`](https://github.com/dashpay/dash/blob/c14104b172a2/src/coinjoin/options.h#L19) ([clamp](https://github.com/dashpay/dash/blob/c14104b172a2/src/coinjoin/options.cpp#L72)). The new regression test `rebalance_never_immediately_reverses` checks every goal from 10 to 200 and every pair of counts from 0 to twice the goal: after any promotion the matching demotion must not fire, and the reverse. Run against unfixed develop (c14104b) with only the test added, it fails 710 times, at exactly goals 10 through 24, and the 10/7 example above is among the failures: <details><summary>Unfixed run (abridged)</summary> ``` $ src/test/test_dash --color_output=false --run_test=coinjoin_inouts_tests/rebalance_never_immediately_reverses Running 1 test case... test/coinjoin_inouts_tests.cpp:1386: error: in "coinjoin_inouts_tests/rebalance_never_immediately_reverses": goal 10: demoting 5/0 is undone by a promotion test/coinjoin_inouts_tests.cpp:1386: error: in "coinjoin_inouts_tests/rebalance_never_immediately_reverses": goal 10: demoting 6/0 is undone by a promotion ... test/coinjoin_inouts_tests.cpp:1383: error: in "coinjoin_inouts_tests/rebalance_never_immediately_reverses": goal 10: promoting 10/7 is undone by a demotion ... test/coinjoin_inouts_tests.cpp:1383: error: in "coinjoin_inouts_tests/rebalance_never_immediately_reverses": goal 24: promoting 25/19 is undone by a demotion *** 710 failures are detected in the test module "Dash Core Test Suite" exit=201 ``` Goals with failures: 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24. </details> ### Why it matters A wallet with a low goal can keep promoting and demoting the same value indefinitely. Each round pays mixing fees and puts another 10-input promotion and 1:10 demotion on-chain, which works against the privacy that rebalancing is meant to protect. The cycle is slow, because demoted outputs have to be remixed before they can be promoted again, and it only affects the wallet owner: no funds are lost and nothing outside the wallet changes. ## What was done? - Added `MIN_GAP_THRESHOLD = (PROMOTION_RATIO + 1) / 2` (5) in `src/coinjoin/common.h`, with the `2 * gap + 1 > PROMOTION_RATIO` derivation in its comment. - `GetGapThreshold` now returns `std::max(nGoal / GAP_DIVISOR, MIN_GAP_THRESHOLD)`. - Added the `rebalance_never_immediately_reverses` test to `src/test/coinjoin_inouts_tests.cpp`, next to the existing gap-threshold tests. ### Why this is the correct minimal fix A promotion needs `Dl > Ds + g`. Afterwards `Dl` drops by 1 and `Ds` rises by at most `PROMOTION_RATIO`. Capping deficits at the goal only shrinks these changes. A demotion right after would need `Ds' > Dl' + g`, so `Ds' >= Ds + 2g + 1`, which is impossible once `2g + 1 > PROMOTION_RATIO`. Demote-then-promote is symmetric. Five is the smallest gap that satisfies this, and it only changes goals 10 to 24. Goals of 25 and above, including the default of 50, keep their current threshold. The floor stays below the goal, so conversion is still reachable at the minimum goal: at goal 10 the extreme 10-vs-0 imbalance (gap 10 > 5) still promotes and demotes. The existing `gap_threshold_reachable_at_every_goal` test, which guards against the threshold disabling the feature, still passes unchanged. Adding a cooldown or remembering past conversions would also stop the loop, but it would need new wallet state when the threshold alone is the root cause. The deficit logic and the fully-mixed gates are unchanged. ## How Has This Been Tested? Built `src/test/test_dash` on macOS arm64 (`--enable-debug --enable-werror`). - Before the fix (develop c14104b + new test only): `src/test/test_dash --run_test=coinjoin_inouts_tests/rebalance_never_immediately_reverses` fails with 710 failures, all at goals 10 to 24 (see above). - After the fix: - `src/test/test_dash --run_test=coinjoin_inouts_tests/rebalance_never_immediately_reverses`: no errors. - `src/test/test_dash --run_test=coinjoin_inouts_tests`: 52 test cases, no errors. This includes `gap_threshold_reachable_at_every_goal` and the other promote/demote decision tests. - `coinjoin_tests` (14 cases), `coinjoin_queue_tests` (11), `coinjoin_dstxmanager_tests` (5): no errors. - `contrib/devtools/clang-format-diff.py` on the diff reports no changes. `test/lint/lint-whitespace.py`, `lint-includes.py`, `lint-format-strings.py`, `lint-tests.py` and `lint-circular-dependencies.py` pass. ## Breaking Changes None. With `-coinjoindenomsgoal` between 10 and 24, the deficit gap a conversion needs rises from 2–4 to 5. No other behavior changes. This fixes a regression introduced in the v24.0.0 release candidates and should also go to the v24.0.x branch. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

…nce validation is enabled d77f357 fix(init): restore the txindex requirement when governance validation is enabled (pasta) Pull request description: ## Issue being fixed or feature implemented Governance validation looks up each proposal's collateral transaction through the transaction index. Without `-txindex`, every proposal fails validation with "Invalid proposal collateral". Until v23.1.0 `dashd` refused to start with governance enabled and `-txindex=0` outside regtest: > Transaction index can't be disabled with governance validation enabled. Either start with -disablegovernance command line switch or enable transaction index. Commit 91129d4 ("refactor: drop dead code with ERROR_TXINDEX_DISABLED_WHEN_GOV_ENABLED", merged in dashpay#7008) removed this check from `LoadChainstate`. Its commit message says governance is now force-disabled in this case and the "governance validation disabled" warning is shown instead. That is not the case: only `-prune` soft-sets `-disablegovernance`. An explicit `-txindex=0` on a non-pruned mainnet, testnet or devnet node that is not a masternode now starts quietly with governance enabled and no transaction index. That node then rejects every proposal it is asked to submit or receives from peers, and adds misbehavior score to each peer that relays one. ### Why this is a real problem Code path at c14104b: - The only parameter interaction that turns governance off is the `-prune` one: [src/init.cpp#L1083-L1091](https://github.com/dashpay/dash/blob/c14104b172a2/src/init.cpp#L1083-L1091). The txindex requirement applies only to masternodes ([src/init.cpp#L1398-L1400](https://github.com/dashpay/dash/blob/c14104b172a2/src/init.cpp#L1398-L1400)), the warning fires only when `-disablegovernance` is set ([src/init.cpp#L1442-L1447](https://github.com/dashpay/dash/blob/c14104b172a2/src/init.cpp#L1442-L1447)), and governance is enabled based solely on `-disablegovernance` ([src/init.cpp#L1732](https://github.com/dashpay/dash/blob/c14104b172a2/src/init.cpp#L1732)). - `CGovernanceObject::IsCollateralValid` finds the collateral only through `g_txindex` and fails with "Can't find collateral tx" when it is null: [src/governance/object.cpp#L796-L806](https://github.com/dashpay/dash/blob/c14104b172a2/src/governance/object.cpp#L796-L806). Proposals then fail `IsValidLocally` ([src/governance/object.cpp#L738-L741](https://github.com/dashpay/dash/blob/c14104b172a2/src/governance/object.cpp#L738-L741)), and `ProcessObject` returns false ([src/governance/governance.cpp#L266-L269](https://github.com/dashpay/dash/blob/c14104b172a2/src/governance/governance.cpp#L266-L269)). - For a proposal received from a peer, a false return from `ProcessObject` adds 20 misbehavior points to that peer: [src/governance/net_governance.cpp#L193-L198](https://github.com/dashpay/dash/blob/c14104b172a2/src/governance/net_governance.cpp#L193-L198). After five proposals the peer reaches the discouragement threshold and, unless it is a manual or `noban` connection, is disconnected and its address discouraged: [src/net_processing.cpp#L5833-L5869](https://github.com/dashpay/dash/blob/c14104b172a2/src/net_processing.cpp#L5833-L5869). The reproductions below ran against an unfixed `dashd`: Parts A and B against c14104b, Part C against the branch rebased on 8819507 with the `src/init.cpp` hunk reversed (nothing between those two commits touches C++). They are small `BitcoinTestFramework` scripts. Part A uses devnet because regtest is exempt from the check. The framework cannot mine the devnet genesis block, so Parts B and C show the effects on regtest, where `-txindex=0` with governance is allowed on every revision. The collateral lookup and peer scoring are the same on every network. <details> <summary>Part A (devnet): a node with <code>-txindex=0</code> starts with governance enabled and no warning</summary> ``` $ DASH_WORKTREE=<worktree> python3 repro_a_devnet_startup.py --configfile=<worktree>/test/config.ini TestFramework (INFO): Start a devnet node with -txindex=0 (governance not disabled) TestFramework (INFO): RESULT: dashd started; stderr: '' TestFramework (INFO): getindexinfo: {} TestFramework (INFO): debug.log: ...

Nothing at startup tells them anything is wrong, and: - `gobject list`/`count`, the governance view in the GUI and proposal vote tracking stay empty or incomplete, and `gobject submit` fails with an unhelpful collateral error. - The node does not relay proposals. - Every honest peer that relays five or more proposals to it, which on mainnet includes any peer it syncs governance objects from, reaches the discouragement threshold and is disconnected; non-local peers are also discouraged. This applies to its outbound peers as well as inbound ones, so the misconfigured node keeps losing its own connections. Trigger and superblock validation do not use the transaction index, so block validation is not affected. The regression was introduced in v23.1.0. It is not a v24.0.0 release-candidate regression. ## What was done? Restored the check in `AppInitParameterInteraction`, next to the other governance and masternode parameter checks. Outside regtest, if governance validation is enabled and `-txindex` is disabled, `dashd` now fails to start with the original error message. Added `feature_governance_txindex_devnet.py`. It runs on devnet, because regtest is exempt, and checks two things: `-txindex=0` alone is refused with that error, and `-txindex=0 -disablegovernance` still starts with the governance-disabled warning. ### Why this is the correct minimal fix - It brings back the behavior from before 91129d4: the same condition, the same translatable message and the same regtest exemption. It is a parameter check, so it lives with the other parameter checks instead of going back into `LoadChainstate`. That needs no changes to the `LoadChainstate` signature or to `ChainstateLoadingError`, and it fails before the block index is loaded. - The regtest exemption is kept on purpose. Many regtest functional tests run with `-txindex=0` and governance enabled (`feature_reindex.py`, `rpc_blockchain.py`, `rpc_misc.py`, `feature_unsupported_utxo_db.py`), as they did before the check was removed. - The alternative is to do what the 91129d4 commit message describes: soft-set `-disablegovernance` when `-txindex=0`. That would change behavior instead of restoring it, and it would quietly turn governance off for an operator who may simply have forgotten the index. A clear startup error matches how the neighbouring incompatible combinations are handled, such as `-prune` with `-disablegovernance=false`. If reviewers prefer the soft-set, it is an equally small change. - Unchanged: `-prune` still soft-sets `-disablegovernance`/`-txindex=0` and keeps its own error for `-disablegovernance=false`. A masternode with `-txindex=0` still gets the existing "Masternode must have transaction index enabled" error first, because the masternode block runs before the new check. The peer scoring in `net_governance.cpp` is left as is; with the check restored, a node that would score honest peers for valid proposals can no longer start outside regtest. ## How Has This Been Tested? Built on macOS arm64 (`--enable-debug --without-gui --enable-werror`). - New regression test against the unfixed `dashd`: `test/functional/test_runner.py feature_governance_txindex_devnet.py` fails. The node does not exit and keeps running with `-txindex=0`: `dashd should have exited within 60s with expected error Error: Transaction index can't be disabled with governance validation enabled. ...`. - The same test with the fix: passes (2-3 s), before and after rebasing onto 8819507. - Reproduction Part A with the fix: `dashd refused to start (exit 1); stderr: Error: Transaction index can't be disabled with governance validation enabled. Either start with -disablegovernance command line switch or enable transaction index.` `-txindex=0 -disablegovernance` still starts with the warning. Parts B and C are regtest-only and are unaffected by the fix, as intended. - Related existing functional tests with the fix, all passed: `feature_config_args.py`, `feature_governance_objects.py`, `feature_masternode_params_devnet.py`, `p2p_connect_to_devnet.py`, `feature_reindex.py`, `rpc_blockchain.py` (v1 and v2 transport), `rpc_misc.py`, `wallet_import_rescan.py --legacy-wallet`. `feature_unsupported_utxo_db.py` was skipped locally (it needs previous-release binaries and Linux). - Lint: `lint-whitespace.py`, `lint-python.py`, `lint-files.py`, `lint-tests.py`, `lint-format-strings.py`, `lint-python-dead-code.py`, `lint-qt-translation.py` are clean. The C++ hunk is formatted with `contrib/devtools/clang-format-diff.py`. ## Breaking Changes Outside regtest, a node started with `-txindex=0` and without `-disablegovernance` now refuses to start, as it did before v23.1.0. Such a node could not validate proposals anyway. To keep running without the index, operators add `-disablegovernance`. The same applies to `-reindex-chainstate` runs, which already require `-txindex=0`. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) ACKs for top commit: knst: utACK d77f357 Tree-SHA512: 55ca460164adbe6e77ec7ba926e9d07516c20ee0162a86c2d98551ca47712090e03b08948929f40c7221ab9741b4ce8a6369b80a6800e4526f0efeaad147443c (cherry picked from commit 248a9d9)

…s start/timeout window dcff069 fix: only sign EHF signals inside the deployment's start/timeout window (pasta) Pull request description: ## Issue being fixed or feature implemented Masternodes create and mine MnEHF (DIP-0023) signals for deployments whose start/timeout window is not open, including deployments that are `NEVER_ACTIVE`. `CEHFSignalsHandler::UpdatedBlockTip()` asks the mnhf quorum to sign a signal for every `useEHF` deployment whose bit has not been mined yet, as long as `CChainParams::IsValidMNActivation()` returns true. That function is the validation check, and it is deliberately permissive: - A `NEVER_ACTIVE` start time is `-2`, so `timePast < nStartTime` is never true and the deployment counts as in range. - A deployment outside of its window is skipped with `continue`, and then the "unknown MnEHF fork bit" fallback returns true. Validation needs that fallback so that old signals on a reused bit stay valid on reindex (`mnhf_bit_reuse_reindex_tests`). So the producer signs regardless of the window. On mainnet today V24 is on bit 13 with `nStartTime = NEVER_ACTIVE`, so as soon as enough mainnet masternodes run this code they will sign and mine a bit-13 signal. Setting a future mainnet start time would not help either: that case goes through the fallback and is signed too. This has happened before. 1be3ac2 ("fix: move DEPLOYMENT_V24 to a fresh version bit") moved V24 off bit 12 because bit 12 "already has mined MNHF signals on mainnet and testnet from before V24 had a start time". That commit moved the bit but left the producer unchanged, so bit 13 would go the same way. ### Why this is a real problem Code path at c14104b (unchanged on current develop): - The producer only checks that the signal is missing and `IsValidMNActivation()`: [src/llmq/ehf_signals.cpp#L45](https://github.com/dashpay/dash/blob/c14104b172a2/src/llmq/ehf_signals.cpp#L45) - `IsValidMNActivation()` skips out-of-window deployments and then accepts unknown bits: [src/chainparams.cpp#L109-L131](https://github.com/dashpay/dash/blob/c14104b172a2/src/chainparams.cpp#L109-L131) - Mainnet V24 is bit 13, `NEVER_ACTIVE`: [src/chainparams.cpp#L212-L213](https://github.com/dashpay/dash/blob/c14104b172a2/src/chainparams.cpp#L212-L213) - Validation uses the same check, so the signal is accepted into the mempool and blocks: [src/evo/mnhftx.cpp#L124-L126](https://github.com/dashpay/dash/blob/c14104b172a2/src/evo/mnhftx.cpp#L124-L126), [src/evo/mnhftx.cpp#L237-L240](https://github.com/dashpay/dash/blob/c14104b172a2/src/evo/mnhftx.cpp#L237-L240) - A mined signal only expires if its MTP is below a positive `nStartTime`, so nodes with `NEVER_ACTIVE` keep it forever and reject any later signal for that bit as `bad-mnhf-duplicate`: [src/evo/mnhftx.cpp#L80](https://github.com/dashpay/dash/blob/c14104b172a2/src/evo/mnhftx.cpp#L80), [src/evo/mnhftx.cpp#L232-L235](https://github.com/dashpay/dash/blob/c14104b172a2/src/evo/mnhftx.cpp#L232-L235) Reproduction: the updated `feature_mnehf.py` from this PR, run against a `dashd` without the `src/llmq/ehf_signals.cpp` change. The test starts the `testdummy` deployment (bit 28) as `NEVER_ACTIVE` (`-vbparams=testdummy:-2:...`), mines two blocks and checks the masternode's log. The unpatched masternode tries to sign it on every new tip: <details> <summary>feature_mnehf.py against unpatched dashd</summary> ``` TestFramework (INFO): Check that masternodes do not sign testdummy while it is NEVER_ACTIVE AssertionError: [node 1] Unexpected message "bit=28 at height" partially matches log: - ... [trySignEHFSignal] [ehf] CEHFSignalsHandler::trySignEHFSignal: already signed bit=28 at height=175 id=a0eee872d7d3170dd20d5c5e8380c92b3aa887da5f63d8033289fafa35a90691 ``` </details> ### Why it matters If v24.0.0 ships like this, upgraded mainnet masternodes will mine a bit-13 signal long before V24 has a start time. Nodes whose V24 start time is still `NEVER_ACTIVE` (v24.0.0 itself) never expire that signal, so when the real signal is mined after a later release sets the start time, those nodes reject that block as `bad-mnhf-duplicate`. If the start time were instead set at or before the early signal, the early signal would count toward activation. In both cases the bit cannot be used cleanly any more, which is what already happened to bit 12. Nothing outside the masternode set can trigger this. It happens on its own once the quorum runs the code. This should also go to v24.0.x: v24.0.0-rc.1 and rc.2 carry V24 on bit 13 with mainnet `NEVER_ACTIVE` and the same producer code. ## What was done? In `CEHFSignalsHandler::UpdatedBlockTip()`, a deployment is now skipped unless its own signalling window is open at the tip MTP: `nStartTime != NEVER_ACTIVE && nStartTime <= MTP && MTP <= nTimeout`. The existing "not mined yet" and `IsValidMNActivation()` conditions are kept as they were. `feature_mnehf.py` gets a new first step, `test_no_signing_outside_window()`, which runs right after the first quorum is mined and before the existing testdummy activation flow: - `testdummy` starts as `NEVER_ACTIVE`, then the nodes are restarted with a window that has already timed out (`0:1`) and one that starts 10 minutes in the future. In each case two blocks are mined and the test checks that the masternode logged no signing attempt for bit 28 and that its mempool has no bit-28 signal. - Mocktime is then moved past the start time and the test waits until the masternode signs `testdummy`, so the negative checks are not passing just because the masternode cannot sign. - The rest of the test is unchanged. It uses `testdummy` rather than `v24`, so it keeps working after v24 is buried. ### Why this is the correct minimal fix The wrong decision is made in the producer, so the fix goes there. `IsValidMNActivation()` cannot be tightened instead. It is the validation check, and its fallback for out-of-window and unknown bits is what keeps old signals valid on reindex after a bit is reused (`mnhf_bit_reuse_reindex_tests`). Changing it would make nodes disagree about blocks they already accepted. `CheckMNHFTx()` and `CMNHFManager::ProcessBlock()` are not touched, so consensus is unchanged: a signal mined by an old node is still accepted exactly as before. The `NEVER_ACTIVE` check has to be explicit. It is the mainnet case, and the plain range check treats `-2` as an already-passed start time. Deployments with `ALWAYS_ACTIVE` (`-1`) or a past start and `NO_TIMEOUT` still pass, so regtest/devnet deployments (start 0) and testnet V24 (its window opened 2026-09-24) are signed as before. Checking the tip MTP is enough. The signal is judged later by the MTP of the block that includes it, and that MTP is greater than or equal to the tip's. I did not add a re-check in `HandleNewRecoveredSig()`. It only submits signals for request ids that `trySignEHFSignal()` registered, and those are only registered while the window is open. ## How Has This Been Tested? macOS arm64, `--enable-debug` build. - `test/functional/feature_mnehf.py` against a `dashd` without the `src/llmq/ehf_signals.cpp` change: fails at the NEVER_ACTIVE check (output above). - `test/functional/feature_mnehf.py` with this PR: passes. - Each condition of the new check was removed in turn, and every variant fails in the step meant to catch it: - Without the `NEVER_ACTIVE` check, the "while it is NEVER_ACTIVE" step fails. - Without `MTP <= nTimeout`, the "after its timeout" step fails. - Without `nStartTime <= MTP`, the "before its start time" step fails. - `test/functional/feature_asset_locks.py` with this PR: passes. It activates regtest v24 (start 0) through masternode-signed EHF. - `src/test/test_dash --run_test=evo_mnhf_tests` (includes `mnhf_bit_reuse_reindex_tests`): passes. - `test/lint/lint-python.py`, `test/lint/lint-whitespace.py` and `contrib/devtools/clang-format-diff.py` on the diff: clean. ## Breaking Changes None. Consensus validation is unchanged. Masternodes no longer create signals for deployments whose window is not open. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) ACKs for top commit: knst: utACK dcff069 Tree-SHA512: 627f886a0b45e5ce807e7f306fa39606dd30bd24eb119479f9810929f3dad1c06005eeb237f5c0096d7d8835d35e0017f79fa831f800c22f5f63d8ba1b19d508 (cherry picked from commit 3a22d16)

…e object lock 96767a4 fix: read deletion flags before deletion time in CheckAndRemove (pasta) ebb27a3 fix: guard cached governance object flags with the object lock (pasta) 94df4f1 refactor: give CGovernanceObjectVoteFile a copy assignment operator (pasta) 059bf00 refactor: require cs in CGovernanceObject::CountMatchingVotes (pasta) Pull request description: ## Issue being fixed or feature implemented `gobject get` can report wrong values for `fCachedFunding`, `fCachedValid` and `fCachedEndorsed` while the node is recomputing them. For example, a proposal that has reached the funding threshold can come back as `fCachedFunding: false`, and a proposal the network voted invalid can come back as `fCachedValid: true`. The reads are also a data race on plain `bool` members. That is undefined behavior, and ThreadSanitizer reports it (see below). There are two causes: 1. The cached flags (`fCachedFunding`, `fCachedValid`, `fCachedDelete`, `fCachedEndorsed`, `fDirtyCache`) have no lock. Readers take no lock: - `CGovernanceObject::GetStateJson()`, used by `gobject get`. - The copy constructor, used by `gobject list`, `gobject diff` and the Qt proposal list through `GetAllNewerThan()`. No single outer lock covers the writers either: - `CGovernanceManager::CheckAndRemove()` holds `cs_main` + `cs_store`. - `SuperblockManager::IsSuperblockTriggered()` holds only `cs_sb`. It is called from block-template creation and block validation, and also from the `masternode winners` RPC without `cs_main`. - The vote path writes `fDirtyCache` while holding the object's own `cs`. 2. `CGovernanceObject::UpdateSentinelVariables()` first resets `fCachedFunding`/`fCachedEndorsed` to `false` and `fCachedValid` to `true`. It then counts votes, and only after that writes the real values. A reader that runs during this window sees the defaults instead of the old or the new result. There is also a related ordering bug. `fCachedDelete` was set before the lock that sets `nDeletionTime`. `CheckAndRemove()` reads `GetDeletionTime()` and then `IsSetCachedDelete()` in separate calls. If `IsSuperblockTriggered()` marks a trigger for deletion in between, `CheckAndRemove()` sees a set delete flag with a zero deletion time, computes `now - 0`, and erases the object immediately instead of after `GOVERNANCE_DELETION_DELAY`. Block validation itself is not affected. Its `IsSuperblockTriggered()` call holds `cs_main` and `cs_sb`, which already serializes it against the other writers. The visible impact is on RPC/GUI output, plus undefined behavior under the C++ memory model. ### Reproduction A throwaway test case (not part of this PR) in `governance_vote_processing_tests` reuses its single-masternode fixture. The masternode votes YES on funding and NO on validity, so with `nGovernanceMinQuorum=1` the correct state never changes: `fCachedFunding=true`, `fCachedValid=false`.

The flags are now protected by the object's existing `cs` mutex, the same lock that already guards `fExpired`, `nDeletionTime` and the vote maps. Clang's thread-safety analysis enforces it. 1. **`refactor: require cs in CGovernanceObject::CountMatchingVotes`.** `CountMatchingVotes()` becomes a private helper with `EXCLUSIVE_LOCKS_REQUIRED(cs)`. The public `Get{Yes,No,Abstain}Count()` wrappers take the lock. No behavior change. This lets one critical section count several signals. 2. **`refactor: give CGovernanceObjectVoteFile a copy assignment operator`.** `CGovernanceObjectVoteFile` has a copy constructor that rebuilds `mapVoteIndex` (list iterators) against its own list, but no copy assignment. The implicit one can't be instantiated because `CGovernanceVote` is not assignable. This commit adds one with the same rebuild semantics, so the copy constructor in commit 3 can copy the vote file while holding the source's lock. A unit test checks that a copy-assigned file is still usable after its source is destroyed. 3. **`fix: guard cached governance object flags with the object lock`.** - The five flags are `GUARDED_BY(cs)`, and the `IsSetCached*()`/`IsSetDirtyCache()` getters take the lock, like `IsSetExpired()`. - `UpdateSentinelVariables()` counts the votes and writes every flag inside one `LOCK(cs)`. Each flag is assigned its computed value directly, with no reset to a default first. This means: - readers see either the previous result or the new one; - two recomputes running at the same time can't interleave flag by flag; - `fDirtyCache = false` is ordered with the vote counts under the same lock that vote writers already hold, so a vote arriving during a recompute still marks the object dirty. - `PrepareDeletion()` and `UpdateSentinelVariables()` share a private `MarkForDeletion()` helper that sets `fCachedDelete` and `nDeletionTime` together, so `fCachedDelete` implies a non-zero deletion time. - `GetStateJson()` reads all four flags under one lock, so `gobject get` returns a consistent snapshot. - The copy constructor copies all `cs`-guarded state while holding `other.cs`. - The computed values are the same as before. 4. **`fix: read deletion flags before deletion time in CheckAndRemove`.** `CheckAndRemove()` now reads `IsSetCachedDelete()`/`IsSetExpired()` before `GetDeletionTime()`. - `fCachedDelete` is never cleared, and it now changes together with `nDeletionTime`, so a set delete flag is always paired with its deletion time. - `fExpired` is only set by `SuperblockManager::Clean()`. That runs from `CheckAndRemove()` itself and stamps the deletion time before this loop. ### Locking notes - No code holds a governance object's `cs` while calling the getters, `UpdateSentinelVariables()`, `PrepareDeletion()`, `GetStateJson()`, or the copy constructor. The external `cs` holders only touch the vote file. - `UpdateSentinelVariables()` and `GetStateJson()` take no other lock while holding `cs`. - The `cs_main`/`cs_store`/`cs_sb` → `obj.cs` edges already existed through `GetYesCount()` and the old `UpdateSentinelVariables()`. No new lock-order edges are introduced. ### Intentionally left unchanged `fCachedLocalValidity`, `strLocalValidityError` and `fUnparsable` follow the same unguarded pattern. However, `GetStateJson()` recomputes local validity instead of reading the cache, and I found no concurrent reader of those fields, so they are out of scope here. ## How Has This Been Tested? macOS arm64, Apple clang. Built with depends using `--disable-hardening --enable-debug --enable-crash-hooks --enable-stacktraces --enable-suppress-external-warnings --without-gui --enable-tests --disable-bench --disable-fuzz-binary --enable-werror`. This enables `-Wthread-safety` as an error. - **Each commit builds on its own.** - **Thread-safety annotations are enforced.** As a mutation check, I removed the `LOCK(cs)` in `GetStateJson()`. The build then fails with `passing variable 'fCachedValid' by reference requires holding mutex 'cs' [-Werror,-Wthread-safety-reference]`. - **Reproduction above with this PR:** 0 wrong reads across three runs (148887, 155774 and 184427 reads). - **ThreadSanitizer build (`--with-sanitizers=thread`) with this PR.** The reproduction ran with a second reader added that also copy-constructs the object each iteration (the `gobject list` path). Result: no ThreadSanitizer warnings and 0 wrong reads. The same binary built from the unfixed tree reports the data race shown above. - **Regression test status.** The reproduction is not included as a regression test. It is a timing-dependent multithreaded test that runs for several seconds, and this race can't be checked deterministically in a unit test. The `CheckAndRemove()` ordering fix has the same limitation; I verified it by reviewing every writer of `fCachedDelete`, `fExpired` and `nDeletionTime`. - **New unit test:** `governance_vote_sync_tests/copy_assigned_vote_file_indexes_its_own_votes`. - `src/test/test_dash --run_test='governance*'`: `*** No errors detected`. - `test/functional/test_runner.py feature_governance.py feature_governance_cl.py feature_governance_objects.py`: all passed. - `git diff -U0 develop | contrib/devtools/clang-format-diff.py -p1` is clean except for the `LogPrint` in `CheckAndRemove()`. That call keeps its existing layout because `test/lint/lint-logs.py` needs the format string's `\n"` on the same line as `LogPrint(`. `lint-logs`, `lint-format-strings`, `lint-includes`, `lint-whitespace`, `lint-assertions`, `lint-include-guards`, `lint-locale-dependence` and `lint-circular-dependencies` pass locally. ## Breaking Changes None. RPC output fields and values are unchanged. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

…allet if migration exited early, keep mixed watchonly txs) 17b0589 test: test migration of tx with both spendable and watchonly (pasta) 03821b7 fix(wallet): keep txs that belong to both watchonly and migrated wallets (pasta) c305aab test: make sure that migration test does not rescan on reloading (pasta) 1f9bf08 fix(wallet): reload the wallet if migration exited early (pasta) Pull request description: ## Issue being fixed or feature implemented `migratewallet` (and the GUI "Migrate wallet" action, which calls the same `MigrateLegacyToDescriptor()`) has two bugs that upstream fixed in bitcoin#28868. That PR is listed as outstanding in the "next batch" section of dashpay#7277. 1. **A failed migration leaves the wallet unloaded.** If the wallet is loaded, `MigrateLegacyToDescriptor()` unloads it first and then runs its checks. Several of those checks return early without loading it again: the wallet is already a descriptor wallet, the backup could not be written, or the passphrase is missing or wrong. After any of these errors the wallet is gone from `listwallets`, and RPC calls to it fail with `Requested wallet does not exist or is not loaded` until the user runs `loadwallet` manually. Mistyping the passphrase once on an encrypted legacy wallet is enough to trigger this. 2. **A transaction with outputs in both resulting wallets only stays in the migrated wallet.** During migration, `ApplyMigrationData()` only offers a transaction to the new `<name>_watchonly` wallet when the migrated wallet does *not* claim it. If one output pays a spendable address and another pays an imported watch-only address, the transaction stays in the migrated wallet and is never copied to `<name>_watchonly`. That wallet is created at the chain tip, so it does not rescan, and its history and balance silently omit that transaction. This is the watch-only bug mentioned in dashpay#7275. ### Why this is a real problem Code path at c14104b: - The loaded wallet is unloaded before any validation: [wallet.cpp#L5006-L5012](https://github.com/dashpay/dash/blob/c14104b172a2/src/wallet/wallet.cpp#L5006-L5012) - These early returns do not reload it: "already a descriptor wallet" [#L5033-L5035](https://github.com/dashpay/dash/blob/c14104b172a2/src/wallet/wallet.cpp#L5033-L5035), backup failure [#L5055-L5057](https://github.com/dashpay/dash/blob/c14104b172a2/src/wallet/wallet.cpp#L5055-L5057), missing or wrong passphrase [#L5062-L5075](https://github.com/dashpay/dash/blob/c14104b172a2/src/wallet/wallet.cpp#L5062-L5075) - Watch-only copying only runs when `!IsMine(tx) && !IsFromMe(tx)`: [wallet.cpp#L4759-L4781](https://github.com/dashpay/dash/blob/c14104b172a2/src/wallet/wallet.cpp#L4759-L4781) I reproduced all three cases against an unfixed `dashd` built from c14104b, using a functional-test-style script on regtest: <details><summary>Reproduction on c14104b (unfixed)</summary> Steps: 1. `createwallet desc` (descriptor), then `migratewallet desc`, then `listwallets` 2. `createwallet enc descriptors=false`, then `encryptwallet pass`, then `migratewallet enc badpass`, then `listwallets` and `getwalletinfo` on `enc` 3. `createwallet imports descriptors=false`, then `importaddress <addr from default wallet>`. From the default wallet, `send` one output to an `imports` address and one to the imported address, then mine a block. Then `migratewallet` and `gettransaction <txid>` on `imports_watchonly` ``` TestFramework (INFO): Case 1: migratewallet on a loaded descriptor wallet TestFramework (INFO): listwallets before: ['default_wallet', 'desc'] TestFramework (INFO): listwallets after: ['default_wallet'] TestFramework (INFO): Case 2: migratewallet on a loaded encrypted legacy wallet with a wrong passphrase TestFramework (INFO): listwallets before: ['default_wallet', 'enc'] TestFramework (INFO): listwallets after: ['default_wallet'] TestFramework (INFO): getwalletinfo on 'enc' -> RPC error -18 (wallet not loaded) TestFramework (INFO): Case 3: tx with a spendable output and a watch-only output TestFramework (INFO): imports_watchonly.gettransaction(cfbc39814ffc474a35bae511c660de7a759653f3a362639f08e38fe2bd6382ef) -> Invalid or non-wallet transaction id (-5) TestFramework (INFO): RESULT descriptor wallet still loaded: False TestFramework (INFO): RESULT encrypted wallet still loaded: False TestFramework (INFO): RESULT mixed tx present in watchonly wallet: False ``` With this branch, the same script reports `listwallets after: ['default_wallet', 'desc']` and `['default_wallet', 'desc', 'enc']`, and all three results are `True`. </details> The upstream tests backported here also fail on the unfixed code (see "How Has This Been Tested?"). ### Why it matters Neither bug loses funds or keys. The first one is a usability trap in a v24 feature: a typo in the passphrase makes the wallet disappear from the node, the GUI and RPC clients, with no hint that a `loadwallet` is needed. The second one leaves the post-migration watch-only wallet with incomplete history and balance, and nothing reports it. Users migrating real wallets have already hit it (see dashpay#7275). ## What was done? Backport of bitcoin#28868, minus one commit: - bitcoin/bitcoin commit `78ba0e6748d2` "wallet: Reload the wallet if migration exited early": remember whether the wallet was loaded (`was_loaded`), define the `reload_wallet` helper before the early exits, and reload the wallet on the descriptor-wallet, backup-failure and passphrase-failure exits. As upstream does, the passphrase unlock moves out of the `LOCK(cs_wallet)` scope so the reload does not happen while the wallet lock is held. - bitcoin/bitcoin commit `71cb28ea8cb5` "test: Make sure that migration test does not rescan on reloading": adds the `migrate_wallet()` helper, which reloads the wallet before migrating and checks that migration does not log `Rescanning`. Because the helper calls `getwalletinfo` on the wallet first, it fails if an earlier failed `migratewallet` left the wallet unloaded. The Dash-only `test_wallet_name_with_slashes` case also goes through the helper. - bitcoin/bitcoin commit `c62a8d03a862` "wallet: Keep txs that belong to both watchonly and migrated wallets": every transaction is offered to the watch-only wallet. It is removed from the migrated wallet only if the migrated wallet does not also own it. - bitcoin/bitcoin commit `4da76ca24725` "test: Test migration of tx with both spendable and watchonly" Dash adaptations and omitted hunks: - **Omitted bitcoin/bitcoin commit `9332c7edda79`** "wallet: Write bestblock to watchonly and solvable wallets". Upstream needs it because, after bitcoin#28609, the watch-only and solvable wallets are created in an empty context and reloaded at the end of migration, and without a best block record they rescan on that reload. Dash has not backported bitcoin#28609. Here those wallets are created with `CreateWallet(context, ...)`, which already writes the chain tip as their best block on first run, and they are not reloaded during migration. The commit fixes nothing on Dash today and belongs with a bitcoin#28609 backport. - 78ba0e6: Dash's "already a descriptor wallet" check (`!GetLegacyScriptPubKeyMan()`) and Dash's backup filename logic are kept as they are. The upstream hunk that moves `reload_wallet` out of the success branch does not apply, because that helper came from bitcoin#28609. The success path keeps its existing direct reload. - c62a8d0: the watch-only copy still uses `AddToWallet()`, because bitcoin#28125 (`LoadToWallet()`/`CopyFrom()` and the shared watch-only `WalletBatch`) is not backported. Only the ownership logic changes, exactly as upstream. - 71cb28e: the upstream hunk that routes `test_addressbook` through `self.migrate_wallet()` is not carried over. That scenario was added by bitcoin#28038, which Dash has not backported, so there is no `test_addressbook` to change. Every other scenario that upstream routes through the helper does so here as well. - 4da76ca: applied to Dash's existing `test_other_watchonly`. The upstream context lines that check copied tx metadata come from bitcoin#28125 and are not part of this change. ### Why this is the correct minimal fix The wallet goes missing because the unload happens before the checks, while only the success path reloads it. Reloading on each early exit is the upstream fix, and every exit taken after the unload but before any database change is covered. Moving the checks ahead of the unload would mean running the backup and the passphrase check against the loaded instance, which is a larger restructuring than this fix needs. As upstream does, no reload is attempted when `MakeWalletDatabase()`/`CWallet::Create()` fail (the same open would fail again) or when `MigrateToSQLite()` fails (by then the original BDB file may already have been removed, and the failed-migration restore path does not run). The `.legacy.bak` file written before a wrong-passphrase exit is also kept, as upstream does. The watch-only change is the upstream one-condition fix, and the rest of bitcoin#28609/bitcoin#28125 is not needed for either bug. The `migratewallet` RPC first shipped in v24.0.0-rc.1 (dashpay#7275/dashpay#7277 are on v24.0.x), so this is a candidate for v24.0.x. ## How Has This Been Tested? macOS arm64, `--enable-debug --enable-werror`, built `dashd`/`dash-cli`/`dash-wallet` at each step. - Reproduction script above: on c14104b it fails with all three bugs present. With this branch it passes. - `test/functional/wallet_migration.py` with only the 71cb28e test change, against the unfixed c14104b binary: **fails** in `test_encrypted`. After the expected wrong-passphrase errors, `migrate_wallet()` → `getwalletinfo` raises `Requested wallet does not exist or is not loaded (-18)`. All earlier migrations pass the no-`Rescanning` check. - Same test after 78ba0e6: passes. - `wallet_migration.py` with the 4da76ca test change, against a binary that has 78ba0e6 but not c62a8d0: **fails** at `watchonly.gettransaction(watchonly_spendable_txid)` with `Invalid or non-wallet transaction id (-5)`. The new listtransactions counts before migration (6) and in the migrated wallet (2) already pass at that point. - Full branch: `test/functional/test_runner.py wallet_migration.py` passes. - `test/lint/lint-python.py` and `test/lint/lint-whitespace.py`: clean. `clang-format-diff` only suggests re-wrapping the passphrase error strings. They keep upstream's layout to stay 1:1, and `wallet.cpp` is not in `non-backported.txt`. ## Breaking Changes None. After a failed `migratewallet`, a wallet that was loaded beforehand is now loaded again, as it was before the call. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) ACKs for top commit: knst: utACK 17b0589 Tree-SHA512: c245f96c7a9a5922ae1ffad9e5c0a3a6eab3494949239cc1d94fab5cdab090239cc13fa4ea3d0a4cd017ef36657aac834d6dd0f84d2bbfd482430ed639e8b1c0 (cherry picked from commit 233aefd) Conflict in test/functional/wallet_migration.py: test_conflict_txs() comes from bitcoin#28542 (dashpay#7762), which v24.0.x does not have, so it is left out along with its migratewallet() -> migrate_wallet() change.

…ind is given and correct the bind release note 5f40d56 partial Merge bitcoin#36170: net: require a dedicated bind for automatic Tor (Konstantin Akimov) 72b3c71 docs: correct when the implicit onion bind is added in release notes (pasta) 5bb8eb3 fix(net): keep a dedicated onion listener when -bind is given (pasta) Pull request description: ## Issue being fixed or feature implemented The backport of bitcoin#22729 (dashpay#7300) changed what happens when a node is started with an explicit `-bind=<addr>` but no `-bind=...=onion`. Before, Dash Core always added the dedicated onion listener `127.0.0.1:9996` (`19996` testnet, `19896` regtest) and pointed the automatically created Tor onion service (`-listenonion`, on by default) at it. Now it binds no onion listener and points the onion service at the first `-bind` address. That listener is not in `onion_binds`, so every peer Tor forwards to it is classified by its source address: Tor's loopback address, or the node's own IP when `-bind` is a routable address. It is not classified as an onion peer. As a result, a node that runs an onion service next to a clearnet address (`-externalip`, or a discovered/bound routable address) advertises its clearnet address to peers that reached it through its `.onion` address. That links the two identities, which the privacy-network check in `GetLocal()` is meant to prevent. Those peers also lose the rest of the onion-specific handling, such as `getpeerinfo` `network` and eviction protection for onion peers. The release note added for dashpay#7300 has a related problem. It says `-listenonion=0` drops the implicit onion bind, but it never did: the bind is added before `-listenonion` is looked at. An operator whose `127.0.0.1:9996` is taken who follows the note still gets a node that refuses to start. Both changes are only in v24.0.0-rc.1 and rc.2. ### Why this is a real problem Code path at c14104b: - [`src/init.cpp#L2678-L2695`](https://github.com/dashpay/dash/blob/c14104b172a2/src/init.cpp#L2678-L2695): with `vBinds` non-empty and no `=onion` bind, `onion_service_target = connOptions.vBinds.front()` ([L2682](https://github.com/dashpay/dash/blob/c14104b172a2/src/init.cpp#L2682)). It is not pushed into `onion_binds`, and `StartTorControl(onion_service_target)` still runs ([L2694](https://github.com/dashpay/dash/blob/c14104b172a2/src/init.cpp#L2694)). - [`src/net.h#L1291`](https://github.com/dashpay/dash/blob/c14104b172a2/src/net.h#L1291) copies only `onion_binds` into `m_onion_binds`. [`src/net.cpp#L1977`](https://github.com/dashpay/dash/blob/c14104b172a2/src/net.cpp#L1977) sets `inbound_onion` only for listeners in `m_onion_binds`. - [`src/net.cpp#L584-L592`](https://github.com/dashpay/dash/blob/c14104b172a2/src/net.cpp#L584-L592): without `m_inbound_onion`, `ConnectedThroughNetwork()` and `IsConnectedThroughPrivacyNet()` fall back to the peer's source address. The privacy filter in `GetLocal()` ([L186-L193](https://github.com/dashpay/dash/blob/c14104b172a2/src/net.cpp#L186-L193)) then skips the node's own onion address for that peer and lets the clearnet one through. I reproduced this on the unfixed build with a small functional-test-style script. A minimal fake Tor control port accepts `PROTOCOLINFO`/`AUTHENTICATE`/`ADD_ONION` and records the target dashd asks Tor to forward to. A P2P peer then connects to exactly that target, as Tor does for every inbound onion connection, and sends `getaddr`. The node runs with `-bind=127.0.0.1:<port> -listenonion=1 -externalip=1.2.3.4`. Unfixed (c14104b): ``` Tor control commands received: ['PROTOCOLINFO 1', 'AUTHENTICATE', 'GETINFO net/listeners/socks', 'ADD_ONION NEW:ED25519-V3 Port=19899,127.0.0.1:17626'] onion-service target handed to Tor: 127.0.0.1:17626 getnetworkinfo localaddresses: [{'address': '1.2.3.4', 'port': 17626, 'score': 4}, {'address': 'pg6mmjiyjmcrsslvykfwnntlaru7p5svn6y2ymmju6nubxndf4pscryd.onion', 'port': 19899, 'score': 4}] Connecting a peer to 127.0.0.1:17626, as Tor would for an inbound onion connection getpeerinfo: addr=127.0.0.1:63442 addrbind=127.0.0.1:17626 network=not_publicly_routable addresses self-advertised to this peer: ['1.2.3.4:17626'] ``` The onion service forwards to the clearnet listener, the forwarded peer is `not_publicly_routable` instead of `onion`, and it is sent the node's clearnet address `1.2.3.4`. In the fixed run the list is empty for two reasons. The privacy filter withholds `1.2.3.4` from an onion peer, and the test `P2PInterface` never sends `sendaddrv2`, so the node cannot send it the v3 onion address either. The fixed run also prints a `wait_until() failed` line after the 10 s wait for addresses; that line is left out of the excerpt above.

Dash Core is probably already running. Error: Failed to listen on any port. Use -listen=0 if you want this. exit=1 ``` ### Why it matters Running an onion service alongside a clearnet address is a supported setup. Operators who also pass an explicit `-bind`, which is common on servers and masternodes, would silently lose the separation between the two once v24.0.0 ships: any peer that connects to the `.onion` address can learn the node's clearnet IP from self-advertisement. Exposure needs a working Tor control connection and a routable local address (`-externalip`, or discovery or a routable `-bind`), so it does not affect every node. Nodes with `-bind` that do not use Tor are unaffected either way. The release-note error is only an operational trap, but it would ship in the v24.0.0 notes. ## What was done? - `src/init.cpp`: drop the branch that used `vBinds.front()` as the onion-service target, so the target is always the first `onion_binds` entry. Without a `-bind=...=onion`, the default onion target is now added to `onion_binds` and used as the Tor target unless `-bind` is given **and** `-listenonion` is disabled. In that one case no onion bind is added and Tor control is not started. `-listenonion` is read after parameter interaction, so `-listen=0` (which soft-sets `-listenonion=0`) is handled as before. The `-bind` help text now mentions the exception. - `doc/release-notes-7300.md`: describe the actual rule. The implicit bind is added unless `-bind` is given together with `-listenonion=0`. `-bind=...=onion` moves it, `-listenonion=0` alone or `-whitebind` alone keeps it, and `-listen=0` disables all binds. - `test/functional/feature_bind_extra.py`: node 2 (explicit `-bind`, no extra port) now says `-listenonion=0` explicitly. Before, it relied on the framework's config default. A new node 3 with explicit `-bind` and `-listenonion=1` must listen on both its `-bind` port and `127.0.0.1:19896`, and a peer connecting to `19896` must show up with `network` `onion`. Node 3's `-torcontrol` points at an unused port so the test never creates an onion service through a Tor instance running on the test host. - `test/functional/feature_proxy.py`: one step starts node 1 with `-listenonion=1` on top of the framework's `bind=127.0.0.1`. With this PR that node would also bind the fixed regtest onion target `127.0.0.1:19896`, which is the port `feature_bind_extra.py` node 3 holds, and since dashpay#7300 a failed bind stops startup. Under `test_runner.py -jN` the two tests could then collide. The step now passes `-bind=127.0.0.1:<tor_port(1)>=onion`, the same per-node port the framework uses when it adds the binds itself. I kept this local to the one test rather than teaching `TestNode.start()` a new rule, because it is the only test that enables `-listenonion` together with an explicit bind. ### Why this is the correct minimal fix The root cause is that the onion service can be pointed at a listener that is not tagged as onion. The only listener that can be both the Tor target and correctly tagged is one in `onion_binds`, so the target must always come from `onion_binds`. The alternative of adding `vBinds.front()` to `onion_binds` would tag every clearnet peer on that port as onion, which leaks the onion address to clearnet peers and distorts eviction, so it is not an option. Two other designs would avoid the multi-instance cost described under Breaking Changes. Both are reasonable, and the choice is up to maintainers: - When `-bind` is given without `=onion` and `-listenonion` is not set explicitly, soft-set `-listenonion=0` during parameter interaction. This keeps rc.1's "respect `-bind`" behavior and avoids the extra bind. The cost is that nodes upgrading from v23 with `-bind` and an automatic onion service would silently lose that onion service. - Keep the default onion bind, but treat a failure to bind it as non-fatal and skip Tor control in that case. This brings back v23's tolerance for this one bind and gives up part of dashpay#7300's "fail on any bind error" rule. This PR does neither. It keeps v23's behavior for the onion service, plus the stricter bind handling from dashpay#7300. bitcoin#22729's goal was to let users avoid the extra `127.0.0.1:9996` bind. This PR keeps that, but only when the user also says they don't want an onion service (`-listenonion=0`). Without an onion service there is nothing to tag. Nothing changes for nodes without `-bind`, with `-bind=...=onion`, or with `-listen=0`. The stricter "fail startup if any bind fails" part of bitcoin#22729 is unchanged too. ### Relation to upstream Bitcoin Core has the same bug. The open upstream fix, bitcoin#36170 ("net: require a dedicated bind for automatic Tor"), has an Approach ACK. It also removes the `vBinds.front()` fallback, but handles the `-bind` + `-listenonion` case differently: instead of adding the default onion bind, it refuses to start until the operator adds `-bind=<addr>=onion` or `-listenonion=0`. That turns every existing `-bind` setup with the default `-listenonion=1` into a startup error, including many masternodes, so this PR keeps v23's default onion bind for that case. The `src/init.cpp` block uses the same layout as bitcoin#36170: the default bind is added up front under one condition, and the Tor target is always `onion_binds[0]` inside the `-listenonion` branch. Backporting bitcoin#36170 later then only changes that condition and adds its errors. bitcoin#36170 also rejects a wildcard `=onion` bind. That is left to the backport, since it is a separate new startup error. This should also go to the v24.0.x release branch, since the behavior was introduced in v24.0.0-rc.1. ## How Has This Been Tested? macOS arm64, `--enable-debug` build, functional tests run outside any sandbox. - Reproduction script above: unfixed build shows the onion target `127.0.0.1:<bind port>`, peer `network=not_publicly_routable`, and the peer is sent `1.2.3.4`. Fixed build shows target `127.0.0.1:19896`, peer `network=onion`, and no clearnet address is sent. - `feature_bind_extra.py` with the new cases. The test is Linux-only (it reads `/proc/net/tcp`), so I ran it locally through a wrapper that swaps `get_bind_addrs()` for an `lsof`-based equivalent and lifts the platform skip. The test itself is unchanged. Nodes 0–2 pass on both builds. - Unfixed (only the `src/init.cpp` hunks reverted): fails at node 3 with `AssertionError: not({('7f000001', 17013)} == {('7f000001', 17013), ('7f000001', 19896)})`. - Fixed: passes, including the `network == "onion"` check. - `feature_proxy.py` with `--nocleanup`, checking the `Bound to` lines in node 1's `debug.log`: - Fixed build without the `feature_proxy.py` change: node 1 binds `127.0.0.1:19896`. This is the collision described above. - Fixed build with the change: node 1 binds only its p2p port and its `tor_port()`, and nothing on `19896`. The test passes. - Unfixed build with the change: same binds, and the test passes. - Release-note cases on the fixed build, with `127.0.0.1:19896` held by another process: `-listenonion=0` alone still fails with `Unable to bind to 127.0.0.1:19896`, as the corrected note says. `-bind=127.0.0.1:18555 -listenonion=0` starts. - `test/functional/test_runner.py feature_proxy.py p2p_eviction.py rpc_net.py` (after the test changes) and earlier `feature_config_args.py`: all passed. `feature_config_args.py` failed once in a `-j4` run with `Unable to start HTTP server` (an RPC port collision with another run on the same host) and passed on rerun. `feature_bind_extra.py`, `feature_bind_port_*.py` and `rpc_bind.py` are skipped on macOS by the runner. CI covers them on Linux. - `test/lint/lint-whitespace.py` and flake8 with the codes enabled in `test/lint/lint-python.py` pass. The `-bind` help line keeps the single-line `AddArg` style of its neighbours rather than the clang-format suggestion. ## Breaking Changes Compared with v24.0.0-rc.1/rc.2 only: a node started with an explicit `-bind` and `-listenonion` enabled (the default) binds `127.0.0.1:9996` (`19996` testnet) again, as v23 did. With the stricter bind handling from dashpay#7300, it fails to start if that port is unavailable. This breaks one setup that works on rc.1/rc.2: several `dashd` instances on one host and one chain, each with its own explicit `-bind`, and `-listenonion` left at its default. For example, several masternodes on separate IPs on one server. On rc.1/rc.2 each instance binds only its own `-bind` address. With this PR every instance also tries to bind `127.0.0.1:9996`; the first one gets it and every later one fails to start. v23 started all of them because a failed bind was only a warning there, and avoiding this extra bind was the reason for bitcoin#22729. Operators with that setup need one of these per instance: - `-listenonion=0`, if the instance does not need an automatic onion service; or - a distinct `-bind=127.0.0.1:<port>=onion` for each instance. Maintainers should weigh this cost against the self-advertisement problem above before merging. The alternatives listed under "Why this is the correct minimal fix" avoid this cost but make other trade-offs. ## Checklist: - [x] I have performed a self-review of my own code - [x] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) ACKs for top commit: knst: self-ACK 5f40d56 Tree-SHA512: 049a3879405756f81ac5fd5a7f1322cc56a1e78d705dd7774e6e0a144fd6a0da0439d9dd106901c91fb3c9dd8395c0143bfa58c363f0b2ec80ffe43ee123312c (cherry picked from commit d721bef)

…oin#29523: weight-check the knapsack exact-match selection d279879 backport: bitcoin#26720: remaining ChooseSelectionResult changes (pasta) 12f213f backport: partial bitcoin#29523: weight-check the knapsack exact-match selection (pasta) Pull request description: ## Issue being fixed or feature implemented When the wallet's small coins add up exactly to the selection target, `KnapsackSolver` returns all of them without checking the max allowed weight. If that set is too heavy for a standard transaction, `ChooseSelectionResult` drops it and the send fails with "The inputs size exceeds the maximum weight. Please try sending a smaller amount or manually consolidating your wallet's UTXOs". This happens even when the wallet has a single larger coin (other than a CoinJoin denomination, see below) that could pay on its own. The knapsack's stochastic path already falls back to that larger coin when its result is too heavy. The exact-match shortcut never got the same check. This affects wallets with many small UTXOs (for example from mining payouts or many small incoming payments) when the fee-adjusted target happens to equal the sum of the coins below it. That is uncommon, but when it happens the send fails with a misleading message. The same send would succeed if the target were slightly different. A second gap comes from the order of earlier backports. The bitcoin#26720 backport (5288a4a) landed before bitcoin#25729 and bitcoin#26661. Because of that, its `ChooseSelectionResult` changes were never applied: the post-selection weight filter is still there, and the specific errors returned by the selection algorithms are discarded. For example, when the knapsack's stochastic path returns its own max-weight error, the user sees a generic "Insufficient funds" instead. ### Why this is a real problem Code path at c14104b: - The exact-match shortcut returns every applicable group without a weight check: [coinselection.cpp#L401-L406](https://github.com/dashpay/dash/blob/c14104b172a2/src/wallet/coinselection.cpp#L401-L406) - The stochastic path does check the weight and falls back to `lowest_larger`: [coinselection.cpp#L453-L458](https://github.com/dashpay/dash/blob/c14104b172a2/src/wallet/coinselection.cpp#L453-L458) - `ChooseSelectionResult` filters the overweight result out and returns the max-weight error: [spend.cpp#L563-L572](https://github.com/dashpay/dash/blob/c14104b172a2/src/wallet/spend.cpp#L563-L572) - Specific knapsack errors are ignored, so a failed knapsack ends as a plain `util::Error()`: [spend.cpp#L544-L561](https://github.com/dashpay/dash/blob/c14104b172a2/src/wallet/spend.cpp#L544-L561) I added a case to `coinselector_tests/check_max_weight` and ran it against the unfixed code. The wallet holds 1500 coins of 0.033 (summing exactly to the 49.5 target, 1500 x 68 bytes = 102,000 bytes, over the limit) plus one 50 coin. Selection should pick the 50 coin, but it fails: <details> <summary>Unfixed code (c14104b + new test case)</summary> ``` $ src/test/test_dash --run_test=coinselector_tests/check_max_weight Running 1 test case... wallet/test/coinselector_tests.cpp:1206: fatal error: in "coinselector_tests/check_max_weight": critical check result has failed *** 1 failure is detected in the test module "Dash Core Test Suite" exit=201 ``` Printing the returned error (temporary `BOOST_REQUIRE_MESSAGE`): ``` wallet/test/coinselector_tests.cpp:1206: fatal error: in "coinselector_tests/check_max_weight": selection error: The inputs size exceeds the maximum weight. Please try sending a smaller amount or manually consolidating your wallet's UTXOs ``` </details> ### Why it matters A user with enough funds, including a single coin that covers the payment, cannot send a specific amount. The error tells them to send less or consolidate, which is wrong advice in this case. Funds are never at risk. Coin control or consolidation works around it, but the user has no reason to know that. ## What was done? Two commits: 1. **partial bitcoin#29523** ([734076c](bitcoin@734076c), knapsack exact-match hunk only). If the exact-match selection is over `max_weight`, the result is cleared and selection falls through to the existing stochastic path. Since the applicable coins sum exactly to the target, that path ends at the existing weight check, which returns the closest larger coin or `ErrorMaxWeightExceeded()` when there is none. The check sits inside Dash's `tryDenom` loop, so the CoinJoin denomination ordering and the `fFullyMixedOnly` / `maxTxFee` check at the end are unchanged. Adds the regression case to `check_max_weight`. 2. **bitcoin#26720, remaining hunks** (`ChooseSelectionResult` part of [1284223](bitcoin@1284223) and [5a2bc45](bitcoin@5a2bc45)). Each algorithm's specific error is collected with `append_error`, and the first one is returned when no algorithm found a solution. The post-selection weight filter is removed, because every algorithm now enforces the max weight itself. The existing overweight case in `check_max_weight` (1515 small coins, no larger coin) now also checks that the max-weight error is reported. ### Why this is the correct minimal fix The root cause is the missing weight check on the exact-match shortcut. The upstream fix for that path is a 3-line hunk, and it is taken as is, using Dash's existing `GetSelectionWeight` helper, which the stochastic path in the same function already uses. Commit 1 on its own would turn the max-weight message into "Insufficient funds" for an overweight exact sum with no larger coin, because `ChooseSelectionResult` discards specific knapsack errors (the knapsack's stochastic path already loses its max-weight error the same way on develop). I confirmed this by running the new assertion with only commit 1 applied. Commit 2 closes that gap with the upstream bitcoin#26720 code. With the knapsack fixed, the post-selection filter can no longer trigger for multi-group results, so removing it, as upstream did, is safe. Intentionally not taken from bitcoin#29523: the `max_tx_weight` RPC funding option, the per-group weight skip, and the weight tracking inside `ApproximateBestSubset`. None of these is needed for this fix. Without the per-group skip, a single `OutputGroup` returned by the knapsack's exact-group or `lowest_larger` paths is not weight-checked during coin selection once the post-selection filter is gone. That needs `avoid_partial_spends` and close to 100 large (e.g. multisig) inputs to one address, and is still rejected later by the "Transaction too large" check in `CreateTransactionInternal`, so only the error message differs. Upstream was in the same state between bitcoin#26720 and bitcoin#29523. Behavior intentionally left unchanged: when only non-denominated coins are considered first (`tryDenom == 0`) and they sum exactly to the target but are overweight, selection falls through to the stochastic path, which at that stage only sees non-denominated coins. If none of them is larger than the target, the knapsack returns the max-weight error without trying a larger CoinJoin-denominated coin. This is how the existing `nTotalLower > target` case already behaves, and it failed before this change too, so it is left for a separate change if needed. User-visible message change: overweight knapsack failures that used to end as "Insufficient funds." or, for CoinJoin sends, "Unable to locate enough mixed funds for this transaction..." now report the max-weight message, as upstream does. Not taken from bitcoin#26720: the test-only commits [ba9431c](bitcoin@ba9431c) (BnB max weight coverage) and [25ab147](bitcoin@25ab147) (test wallet-creation refactor). They are unrelated to this fix, and Dash's `ChooseSelectionResult` passes BnB an empty pool. `AttemptSelection` still returns early on a specific error, the same as upstream. ## How Has This Been Tested? macOS arm64, `--enable-debug --enable-tests --without-gui`. - Unfixed code plus the new exact-sum case: `src/test/test_dash --run_test=coinselector_tests/check_max_weight` fails (output above). - Commit 1 only, with commit 2's new assertion: the exact-sum case passes. The max-weight message assertion on the existing 1515-coin case fails (`coinselector_tests.cpp:1192: error: ... check util::ErrorString(result).original.find("The inputs size exceeds the maximum weight") != std::string::npos has failed`), because the knapsack's error is replaced by a generic one. - Both commits: `src/test/test_dash --run_test=coinselector_tests` passes (10 test cases). `check_max_weight` passed 3 further runs out of 3. `--run_test=spend_tests,wallet_tests` also passes. - Functional: `test/functional/test_runner.py wallet_basic.py wallet_create_tx.py wallet_fundrawtransaction.py wallet_send.py wallet_sendall.py rpc_coinjoin.py` all passed (run before the test-only rework of commit 2; the non-test code is unchanged since). `wallet_sendall.py --descriptors` failed after 1 s in the first parallel run and passed on a standalone rerun. - `test/lint/lint-whitespace.py` passes. The upstream lines in `spend.cpp` are kept verbatim rather than clang-formatted. ## Breaking Changes None. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

…hdseed 409b033 fix: return non-zero amount of accounts after sethdseed (pasta) Pull request description: ## Issue being fixed or feature implemented `migratewallet` fails on a legacy HD wallet whose seed has not derived any key yet: ``` MigrateToDescriptor: legacy HD chain has 0 accounts; migration only supports wallets with a single BIP44 account ``` `sethdseed` with an explicit seed and the `-hdseed` startup path both write the HD chain with `AddHDChainSingle()` first and call `newHdChain.AddAccount()` afterwards, on a local copy that is never read again. The call has been dead code since 266aefc. The chain on disk therefore has an empty account map until `DeriveNewChildKey()` derives the first key and `SetAccount()` creates account 0 as a side effect. `CHDChain::GetAccount()` and `SetAccount()` already treat an empty map as "account 0 with zeroed counters", but `CountAccounts()` reports 0 for the same chain, and `MigrateToDescriptor()` rejects anything but 1. Normally the keypool top-up hides this right away. It does not happen when `sethdseed` is called with `newkeypool=false` and no key is derived before migration. The clearest case is an encrypted wallet: `migratewallet` reloads it locked, so the top-up on load derives nothing, and `MigrateToDescriptor()` then sees a chain with no stored accounts. `getwalletinfo` reports `hdaccountcount: 0` for such a wallet, although the next key will be derived from account 0. The owner of such a wallet cannot migrate it to a descriptor wallet. Migration fails closed and no keys or funds are lost, but the error suggests an unsupported account layout and the workaround (unlock and derive a key before migrating) is not obvious. ## What was done? A seeded chain is one account, whether or not a key has been derived from it yet. That is also how Bitcoin Core's `CHDChain` behaves: `SetHDSeed()` writes a complete chain with zeroed counters in one step, and `MigrateToDescriptor()` reads those counters with no account guard. Commit 1: `CHDChain::CountAccounts()` returns 0 for a null chain and otherwise at least 1. This makes it consistent with `GetAccount()`/`SetAccount()` and fixes all three callers at once: the migration guard, `getwalletinfo` and `dumpwallet`. The guard in `MigrateToDescriptor()` stays `!= 1`, so chains with more than one account are still rejected and the backported file is untouched. Wallets already on disk with an empty account map migrate without any repair step. Commit 2: `sethdseed` and the `-hdseed` path call `AddAccount()` before the chain is encrypted and written, the same order `GenerateNewHDChain()` has always used for mnemonic-based chains. The chain record written for a seed-based wallet is now identical in shape to the one written for every mnemonic-based wallet. Nothing reads the local copy after the write, so removing the old call changes no behavior; the only visible difference is that `getwalletinfo` reports `hdaccountcount: 1` immediately after `sethdseed`. Test: `wallet_hd.py` already builds exactly this state. `wallet_imported_seed` is a blank wallet that receives `sethdseed(False, seed)` and is inspected with `getwalletinfo` before any key is derived. One assertion there checks `hdaccountcount == 1`. On the unfixed tree it reports 0, which is the value the migration guard rejects; either commit alone makes it pass. ## How Has This Been Tested? Run unit & functional tests. ## Breaking Changes None. `getwalletinfo` and `dumpwallet` report one account instead of zero for a seeded legacy chain that has not derived a key yet, which is the account the next derivation uses. The on-disk chain record written by `sethdseed` and `-hdseed` now carries account 0 from the start, which is the same record every mnemonic-based legacy wallet already has, so older binaries read it unchanged. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [x] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ Top commit has no ACKs.

It decides this by comparing each pending update's `validForProTxKey` with the new key. `addUncheckedProTx()` sets that field for ProUpRegTx and ProUpRevTx but not for ProUpServTx, so it stays null and never matches. As a result, every confirmed ProUpRegTx of a masternode evicts all its pending ProUpServTxs, even when the operator key does not change, for example a payout or voting key update. A ProUpServTx is signed by the operator key and is still valid in that case. Evicting it drops a valid transaction together with its InstantSend lock, and the operator has to resubmit it. The mempool's eviction paths for pending updates of a registered masternode also had little test coverage. ## What was done? - `addUncheckedProTx()` records `validForProTxKey` for a ProUpServTx from the operator key at the tip, as it already does for ProUpRegTx and ProUpRevTx. A confirmed ProUpRegTx then evicts the ProUpServTx only if it changes the operator key. If the masternode is not in the tip list, the field stays null and any registrar update still evicts the ProUpServTx, as before. - New coverage for eviction paths that were not tested: - `test_mempool_proreg_replacement_update_conflict`: - a confirmed ProUpRegTx that keeps the operator key, together with a spend of an unrelated output, leaves pending ProUpServTx and ProUpRevTx in place; - one that changes the key evicts them; - a spend of the masternode collateral evicts pending ProUpServTx, ProUpRegTx and ProUpRevTx. - `feature_masternode_shares.py`: in the dissolution reorg scenario, a ProUpSharedRegTx and a ProUpShareTx submitted while the dissolution block is disconnected are gone from the mempool once the block is reconnected. The branch history also contains an eviction of a pending ProRegTx whose external collateral is spent, a follow-up exemption for a ProRegTx whose own collateral output is spent, and a commit reverting both. That change needs to be coordinated with a related InstantSend policy change and will be proposed again separately. The net diff of this PR does not touch `removeProTxSpentCollateralConflicts()`. Known limitation: while a reorg returns disconnected transactions to the mempool, the masternode list tip has not been moved yet. A ProUpServTx re-added at that point can record the operator key from the pre-reorg list. ProUpRegTx and ProUpRevTx entries already take their key the same way. dashpay#7728 moves the list tip before transactions are re-added, which covers all three. Related: dashpay#7728 keeps an operator key change and a ProUpServTx signed with the old key out of the mempool together. It does not change what happens when a ProUpRegTx that keeps the key is confirmed, so the two PRs complement each other. ## How Has This Been Tested? Built on macOS arm64 with `--enable-debug --enable-werror --enable-crash-hooks`. - Removing the `validForProTxKey` assignment makes `test_mempool_proreg_replacement_update_conflict` fail at the check that the ProUpServTx survives a ProUpRegTx that keeps the key. - Disabling the registered-masternode branch of `removeProTxSpentCollateralConflicts()` makes `test_mempool_proreg_replacement_update_conflict` fail at the collateral-spend check, and `feature_masternode_shares.py` fail at the dissolution check. - These mutation checks were run on an earlier head of this branch. The tests and the ProUpServTx fix have not changed since. Run at the current head: - All unit tests: `test_dash`, 1056 cases. - Functional: `feature_masternode_shares.py`, `feature_dip3_deterministicmns.py --descriptors`, `rpc_masternode.py`, `mempool_reorg.py`. - `test/lint/all-lint.py`: the only failure is an existing cppcheck warning in `src/governance/object.cpp`, which this PR does not touch. Python lint was skipped locally because flake8 is not installed; `pyflakes` is clean on the changed functional test. ## Breaking Changes None. Consensus is unchanged and this only affects mempool policy: a pending ProUpServTx is no longer evicted by a confirmed ProUpRegTx that keeps the operator key. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [x] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

… payouts behind a new evo_shares deployment 787ad82 refactor: share platformNodeID handling between provider transactions (pasta) 8edce1f doc: add release notes for the evo_shares deployment (pasta) d42644f test: cover evo_shares signing and EvoNode owner payouts (pasta) b3e6f5e feat(rpc): prepare shared EvoNode registrations (pasta) 9deae1f feat: restrict EvoNode shares and multiple payouts until evo_shares (pasta) 68a9144 feat: add the evo_shares deployment, not signed in v24 (pasta) e4428b7 refactor: pass special transaction deployment rules as a struct (pasta) Pull request description: ## Issue being fixed or feature implemented Platform does not support EvoNodes with shared collateral or with more than one owner payout yet, and asked that v24 not allow them. v24 introduces both (shared masternode collateral and the version 3 payout list), and today an EvoNode can already register or update with several owner payouts; only shared EvoNode registration is rejected, statelessly. This PR keeps both disabled for EvoNodes in v24 and adds a deployment, `evo_shares`, that lifts the restriction later (planned for v24.1, once Platform supports it) without a chain split between v24 and v24.1 nodes. > [!IMPORTANT] > Mainnet `v24` and `evo_shares` start times are both still `TODO`. They must be set to the same value before release. A new unit test (`evo_shares_follows_v24`) fails if `evo_shares`' parameters ever differ from `v24`'s on any network, so the mainnet start time cannot be filled in for only one of them. ### Why v24 does not sign it instead of using a later start time The new deployment's consensus parameters ship in v24 and must be identical in v24.1: `nStartTime` is consensus (it gates versionbits `STARTED`, and an MNHF signal mined before it is treated as expired), so v24.1 cannot move it, and a start time could not express "once enough of the network runs v24.1" anyway. Instead v24 masternodes simply do not sign the `evo_shares` MNHF signal. A masternode-activated deployment cannot start until its signal is mined, so `evo_shares` stays inactive until masternodes running v24.1 sign it; v24 nodes follow it from then on like any other deployment. ## What was done? 1. **refactor:** `SpecialTxRules` (filled by `GetSpecialTxRules()`) replaces the `bool is_v24_active` parameter of `CheckSpecialTx`, `ProcessSpecialTxsInBlock` and their callers, so another deployment can be passed without touching every caller again. No behaviour change. 2. **`DEPLOYMENT_EVO_SHARES`** (`evo_shares`, bit 14, masternode-activated) with `v24`'s window, thresholds and start times on every network. The MNHF signer skips it; v24.1 drops that skip. 3. **Rules**, until `evo_shares` is active: - an EvoNode ProRegTx with a share table is rejected with `bad-protx-shares-evo`. The rule moves from the stateless `CProRegTx::IsTriviallyValid()` into `CheckProRegTx()`; - an EvoNode ProRegTx or ProUpRegTx with more than one owner payout is rejected with the new `bad-protx-payouts-evo`. The ProUpRegTx check also covers operator key rotation; - neither rule needs a v24 gate: share tables and payout lists only exist in version 3 payloads, which need v24. - The shared registration consent digest also covers an EvoNode's `platformNodeID`. Only the digest of EvoNode registrations changes, and those were invalid until now; the digest of a regular shared registration is unchanged. 4. **RPC:** `protx shared_register_prepare_evo` takes the arguments of `protx shared_register_prepare` followed by `platformNodeID`, `platformP2PAddrs` and `platformHTTPSAddrs`. Preparing a shared EvoNode registration fails until `evo_shares` is active. Dash Qt still prepares regular shared registrations only; EvoNode support there is left for v24.1. 5. **Tests and release notes** (below), and a small follow-up refactor that moves `register_evo` / `update_service_evo` onto the `platformNodeID` helpers added for the new RPC. ## How Has This Been Tested? macOS arm64, debug build (`--enable-debug --enable-werror`). - `make check`-equivalent: the full `test_dash` suite passes. - Every commit builds and passes `evo_*`, `versionbits_tests` and `miner_tests` on its own. - New unit tests: - `evonode_registration_needs_evo_shares` / `evonode_payout_update_needs_evo_shares`: table-driven `CheckProRegTx` / `CheckProUpRegTx` cases (EvoNode vs regular masternode, one vs two payouts, shared, operator key rotation, `evo_shares` on/off); - `shared_reg_consent_hash`: `platformNodeID` is covered for EvoNodes and not for regular masternodes; - `evo_shares_follows_v24`. - New functional test `feature_evo_shares_activation.py`: a masternode signs another masternode-activated deployment (`testdummy`) but never `evo_shares`, which stays `defined`; an EvoNode keeps one owner payout until `evo_shares` is active (registration, registrar update, update with operator key rotation). It then lets miners activate `evo_shares` (`-vbparams` with EHF disabled) and checks EvoNodes can update and register with several owner payouts. - `feature_masternode_shares.py`: shared EvoNode preparation fails before activation; the same signed registration is rejected with `bad-protx-shares-evo` in a block below the activation height; after activation it registers, is paid split by shares, updates its Platform service, a share reward and its voting key, and dissolves with a refund to every share. - Mutation checks, run locally: disabling either consensus rule fails exactly the restricted cases of the new unit tests; letting the signer sign `evo_shares` fails `feature_evo_shares_activation.py`. - Also run: `rpc_blockchain.py`, `rpc_help.py`, `feature_mnehf.py`, `feature_versionbits_warning.py`, `mining_basic.py`, `feature_protx_version.py`, `feature_dip3_deterministicmns.py`, `rpc_netinfo.py`, `feature_asset_locks.py`, `wallet_dash_rpcs.py`; Python, whitespace, file, include, assertion and format-string lints. ## Breaking Changes Consensus change to rules that are not active on mainnet or testnet yet: - Testnet: `v24` is not active yet (the tip coinbase is still CbTx version 3), so no historical block is affected. Testnet masternodes should run a build with this change before `v24` activates there, otherwise an EvoNode registered or updated with several owner payouts after activation would split them from upgraded nodes. - Devnets where `v24` is already active (its devnet start time is July 2025): any EvoNode registered or updated there with more than one owner payout makes those blocks invalid for this build, so such devnets need to check (`protx list registered 1`) or be reset. - New RPC `protx shared_register_prepare_evo`. Follow-up outside this repo: the shared masternode DIP should describe the `platformNodeID` field in the EvoNode consent digest. ## Checklist: - [x] I have performed a self-review of my own code - [x] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

Cherry-picked (`git cherry-pick -m1 -x`) every develop merge since rc.2 that carries `backport-candidate-24.0.x`, plus dashpay#7778, which dashpay#7807's test needs.

Needed because dashpay#7807's `feature_evo_shares_activation.py` depends on its `mine_quorum_single_member()` fix and fails without it.) - dashpay#7791 fix(net): request object votes from nPeersPerHashMax peers - dashpay#7781 fix(rpc): use a consistent tip height in quorum dkgstatus - dashpay#7789 fix(qt): report malformed lang/font settings instead of aborting at startup - dashpay#7779 fix!: report legacy evonode Platform addresses when listdiff changes its address - dashpay#7795 backport: bitcoin#34272, partial bitcoin#31650 (pass PSBT by const reference in PSBTInputSignedAndVerified) - dashpay#7783 fix: stop fish completion from re-running the typed dash-cli command - dashpay#7794 fix(wallet): floor the denomination gap threshold so rebalancing cannot oscillate - dashpay#7785 fix: restore the txindex requirement when governance validation is enabled - dashpay#7787 fix: only sign EHF signals inside the deployment's start/timeout window - dashpay#7790 fix: guard cached governance object flags with the object lock - dashpay#7793 backport: partial bitcoin#28868 (wallet: reload wallet if migration exited early, keep mixed watchonly txs) - dashpay#7786 fix(net): keep a dedicated onion listener when -bind is given and correct the bind release note. Includes partial bitcoin#36170 (5f40d56). Upstream's dedicated-onion-bind changes to `feature_torcontrol.py` and `p2p_private_broadcast.py` are not included, because those tests depend on upstream commits (5693833, e74d54e) that Dash does not have. - dashpay#7796 backport: bitcoin#26720 (remaining), partial bitcoin#29523: weight-check the knapsack exact-match selection - dashpay#7803 fix: return non-zero amount of accounts after sethdseed - dashpay#7776 fix: keep a pending ProUpServTx across a registrar update that keeps the operator key - dashpay#7807 feat(consensus): hold EvoNode shares and multiple payouts behind a new evo_shares deployment One pick needed conflict resolution, in a test only, described in its commit message: dashpay#7793, `test/functional/wallet_migration.py`. `test_conflict_txs()` comes from bitcoin#28542 (dashpay#7762), which is not on this branch, so it is left out. The C++ part of dashpay#7793 is identical to develop. Merged since rc.2 but intentionally not included: dashpay#7775 (24.1 version bump), dashpay#7260 and dashpay#7804 (new Qt feature and its CI fix), dashpay#7584 (refactor), routine upstream backports dashpay#7257, dashpay#7759, dashpay#7762, dashpay#7768, dashpay#7788, dashpay#7801, and test/CI-only changes dashpay#7777 and dashpay#7797. No version change is needed. `configure.ac` is already 24.0.0 with `CLIENT_VERSION_IS_RELEASE` false, so the build takes its version string from the `v24.0.0-rc.3` tag, as it did for rc.2. ## How Has This Been Tested? Built on macOS arm64 against depends with `--enable-debug --enable-werror` (dashd, dash-qt, tests). - `make check`: all unit test suites pass, including `test_dash-qt`. - Functional tests, all passing: `feature_evo_shares_activation.py`, `feature_masternode_shares.py`, `feature_mnehf.py`, `feature_governance.py --descriptors`, `feature_governance_objects.py`, `feature_governance_txindex_devnet.py`, `feature_proxy.py`, `feature_notifications.py`, `feature_llmq_connections.py`, `feature_llmq_chainlocks_automatic.py`, `feature_llmq_singlenode.py`, `p2p_instantsend.py`, `rpc_blockchain.py` (v1 and v2 transport), `rpc_netinfo.py`, `rpc_quorum.py`, `rpc_verifychainlock.py`, `wallet_hd.py` (legacy and descriptors), `wallet_migration.py`. - `feature_bind_extra.py` (from dashpay#7786) only runs on Linux and was skipped locally, so CI covers it. Every touched file was diffed against develop. The remaining differences come only from develop PRs that are not part of this backport. ## Breaking Changes Carried over from the picked PRs: - dashpay#7807: consensus change behind the new `evo_shares` deployment (bit 14). Mainnet and testnet are unaffected until it activates. Devnets with `v24` already active and an EvoNode carrying several owner payouts need to check or reset. New RPC `protx shared_register_prepare_evo`. - dashpay#7785: outside regtest, a node with `-txindex=0` and without `-disablegovernance` refuses to start again, as before v23.1.0. - dashpay#7786: carries a partial bitcoin#36170. A node started with `-bind` but no specific `-bind=<addr:port>=onion` now refuses to start while `-listenonion` is enabled. That is the default when listening, even without Tor configured. A wildcard onion bind is also refused. Such nodes need `-bind=127.0.0.1:<port>=onion` or `-listenonion=0`. Nodes without `-bind`, including those using only `-whitebind`, keep the default `127.0.0.1:9996` (`19996` testnet) onion target. See `doc/release-notes-7300.md`. - dashpay#7779: `protx listdiff` now includes `platform_p2p` and `platform_https` for a legacy-address evonode whose core P2P address changes. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

…on recipients b0f8630 fix: restore HTML escaping of send confirmation recipients (Konstantin Akimov) Pull request description: ## Issue being fixed or feature implemented A payment URI can supply a label containing HTML. The send confirmation inserts that label, along with the amount, wallet name and address, into rich text, so tags such as `<br>` change what the user sees while reviewing the recipient. Dash used to escape the label and wallet name here. [Bitcoin Core bitcoin#16826](bitcoin#16826) was already backported as d7281c8 (2021), but that merge did not take the `sendcoinsdialog.cpp` hunks, because Dash's older escaping was still in place at the time. The [bitcoin#15886](bitcoin#15886) backport, a081afd (2022), then rewrote the confirmation text and dropped both `GUIUtil::HtmlEscape(rcp.label)` and `GUIUtil::HtmlEscape(model->getWalletName())`. Since then neither has been escaped. ## What was done? This is a fix that restores the lost escaping. It is not a new backport of bitcoin#16826. Each recipient line is HTML-escaped just before it is joined into the rich-text confirmation. That covers the `sendcoinsdialog.cpp` hunks of both upstream commits from bitcoin#16826: the label escape from [2c530ea](bitcoin@2c530ea) and the wallet-name escape from [1770a97](bitcoin@1770a972d471). The plain-text "Show Details" view is built from the same list before escaping and stays unchanged, so labels with ampersands, angle brackets, quotes or entity text still show literally there. A regression was added to the existing funded-wallet GUI test. It drives labels, including the URI-supplied label `<br>Forged recipient`, through the real send dialog, checks the rendered confirmation text, and cancels the confirmation before the existing send and transaction-list checks run. ## How Has This Been Tested? On macOS arm64 with prebuilt depends and Qt 5.15: - Built `qt/dash-qt` and `qt/test/test_dash-qt`. - `QT_QPA_PLATFORM=cocoa src/qt/test/test_dash-qt` passed in full, exit status 0, including `WalletTests`. The `minimal` platform skips `WalletTests` on macOS. - With the new regression and the `sendcoinsdialog.cpp` change reverted, `WalletTests::walletTests()` failed. The rendered-text check fails for the markup label, and the test then hangs until the Qt test timeout. ## Breaking Changes None. Labels and wallet names now display literally in the rich-text confirmation, as before the bitcoin#15886 backport. Stored labels, transaction recipients, amounts and send behavior are unchanged. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation (not applicable to this display fix) - [ ] I have assigned this pull request to a milestone (maintainer decision) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

…level service field 2fb1e39 fix(rpc): correct masternode status help for top-level service field (thephez) Pull request description: ## Issue being fixed or feature implemented The `masternode status` help says the top-level `service` field is deprecated, optional, and only returned when `-deprecatedrpc=service` is passed. In fact the RPC returns it every time. This key reports the host node's own address, so it was deliberately left out of the `service` deprecation (see `rpc_netinfo.py`). The help text was taken from the shared deprecated entry, which only applies to the nested `dmnState.service` key. ## What was done? - Replaced the shared `GetRpcResult("service", /*optional=*/true)` lookup in `masternode status` with a dedicated, non-optional result entry: "IP address and port of this masternode". - The nested `dmnState.service` key and the shared help entry used by other RPCs are unchanged and still gated by `-deprecatedrpc=service`. ## How Has This Been Tested? Help-text-only change. `rpc_netinfo.py` already asserts that the top-level `service` key is always present in `masternode status` output, which matches the field now being non-optional. ## Breaking Changes None. RPC output is unchanged; only the help text differs. ## Checklist: - [ ] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ Top commit has no ACKs.

3ef0555 fix(evo): check credit pool amount accumulation (pasta) Pull request description: ## Issue being fixed or feature implemented Credit-pool deposit accounting uses unchecked signed addition. `ConnectBlock` runs `ProcessSpecialTxsInBlock` (and with it the credit-pool diff) before `CheckTxInputs`, so asset-lock amounts are accumulated before their funding is checked. A block that stacks enough unfunded `MAX_MONEY` asset locks overflows `sessionLocked`, which is signed-overflow undefined behaviour and terminates trapping builds. Checking representability before mutation turns this into a normal validation failure and keeps correct accounting for representable deposit/withdrawal flows. ## What was done? Use the existing `CheckedAdd` helper for session deposit and withdrawal amounts and the withdrawal output sum. Assign session amounts only after the candidate sum passes. Calculate the final balance with checked arithmetic, subtracting withdrawals before adding deposits and the Platform reward. An unrepresentable final balance throws through the existing validation/mining error paths. The `CAmount` getter API, withdrawal limits and atomic package rollback remain intact. No aggregate or final `MAX_MONEY` rule was added, and the final net balance is checked after processing rather than after each deposit. ## How Has This Been Tested? - Local arm64 macOS build using prebuilt depends: `make -C src dashd test/test_dash` passed. - `./src/test/test_dash --run_test=evo_assetlocks_tests` passed. The new `credit_pool_lock_arithmetic` case accumulates individually in-range deposits to the `CAmount` boundary through the public `ProcessLockUnlockTransaction` API and checks that the next deposit is rejected and leaves the diff unchanged. The existing suite still covers ordinary asset locks and package rollback. The fixture exercises the public bookkeeping interface; it is not a funded-block proof, and full-node exploitability was not reproduced. ## Breaking Changes Successful representable accounting retains its mathematical result. Unrepresentable sums now report an error. No monetary cap or activation rule was added. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone ACKs for top commit: knst: utACK 3ef0555 Tree-SHA512: 461cbd9f11ea078159b1e8166fcb511920b937590dcc83c8b4ccc48db009a34cc975b3fd431920038561cc793242756f9d93dc20ab60c3be079e7f7ceb58947c (cherry picked from commit 21ea7ba)

…rors e5fe71d fix: omit recovery words from invalid mnemonic errors (pasta) Pull request description: ## Issue being fixed or feature implemented Invalid-mnemonic errors included the submitted recovery words. The legacy wallet startup path forwards those errors to stderr and debug.log, exposing recovery material in diagnostics. ## What was done? Remove the words from the two existing error messages. Mnemonic validation, seed derivation and error propagation are unchanged. ## How Has This Been Tested? `make -j1`, the existing `bip39_tests` and `wallet_crypto_tests`, and diff, whitespace and include checks pass. The production edits are identical to the previously validated version: a standalone before/after check with a synthetic public mnemonic confirmed redaction in legacy startup stderr/debug.log and descriptor RPC errors. No test is added by this PR. ## Breaking Changes Invalid-mnemonic errors no longer echo recovery words. ## Checklist: - [x] I have performed a self-review of my own code - [x] Documentation is not needed for this diagnostic change - [ ] I have assigned this pull request to a milestone This pull request was created by Codex.

7a9d1b0 fix: reject malformed detached quorum share batches (pasta) Pull request description: ## Issue being fixed or feature implemented When a detached sig share's lazy BLS signature fails to deserialize, `NetSigning::ProcessPendingSigShares` bans the source and stops collecting its shares, but never adds it to `batchVerifier.badSources`. The dispatch loop then passes that source's whole vector to `CSigSharesManager::ProcessPendingSigShares`, including the malformed share and every unverified share after it. That method assumes its input is already verified, so unverified shares can reach the local share manager and interfere with recovery. ## What was done? In the malformed-signature branch, replace `BanNode(nodeId)` with `batchVerifier.badSources.emplace(nodeId)`. The existing dispatch loop already bans every node in `badSources` once (which also re-requests its shares) and skips its vector, so the malformed source's shares are no longer dispatched. Valid sources go through the same verification path as before. dashpay#7840 changes the same `ProcessPendingSigShares` block (per-signature BLS authentication) and should be rebased over whichever of the two merges first. ## How Has This Been Tested? Verified by inspection and build. No regression test is added, because the one-line change is self-evident from the diff: `badSources` now drives the existing ban-and-skip dispatch loop, and `CBLSBatchVerifier::Verify()` only adds to `badSources` and never clears it. - macOS arm64: `make -C src dashd test/test_dash dash-cli` built cleanly. - `./src/test/test_dash --run_test=llmq_utils_tests` passed. - `test/functional/test_runner.py feature_llmq_signing.py "feature_llmq_signing.py --spork21"` passed. ## Breaking Changes None to consensus rules, historical commitment validation, wire formats, or valid signatures. Detached batches from a source with a malformed share are now dropped instead of dispatched. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone No user-facing documentation change is needed for this internal validation repair. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

…nputs 696c0c0 fix(rpc): handle unavailable masternode payment inputs (pasta) Pull request description: ## Issue being fixed or feature implemented Source inspection shows that `masternode payments` dereferences a nullable previous-transaction lookup while calculating historical block fees. Querying a spending block when historical input data is unavailable can terminate the node. Returning a normal RPC error before the dereference preserves node availability and successful fee calculations. ## What was done? Check the transaction lookup and output index before reading the input amount. Missing transaction data returns `RPC_MISC_ERROR`; an unavailable referenced output returns `RPC_INTERNAL_ERROR`. Queries that do not need historical inputs continue to work without the index, and indexed fee and payment calculations remain unchanged. ## How Has This Been Tested? - `test/functional/test_runner.py rpc_masternode.py` passed on arm64 macOS. It restarts a node with `-txindex=0` and queries `masternode payments` for a block that spends a non-coinbase input; the RPC returns error -1 (`previous transaction not found`) and the node stays responsive. - The pre-fix crash was not reproduced; the out-of-range output check is covered by review only. ## Breaking Changes No changes to successful RPC results or consensus behavior. Missing input data now returns a normal RPC error. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone Top commit has no ACKs.

86ba039 fix(wallet): authenticate unlock deadline extensions (pasta) Pull request description: ## Issue being fixed or feature implemented `CWallet::Unlock(SecureString)` returned `true` without checking the passphrase whenever the encrypted wallet was already fully unlocked. `walletpassphrase` treats that result as authentication and replaces the relock deadline and timer. So while a wallet is fully unlocked, a caller allowed to use `walletpassphrase` could keep it unlocked past the owner's deadline with any nonempty wrong passphrase. Spending or exporting keys after the original deadline still needs those RPC permissions too. A locked or mixing-only wallet cannot be unlocked this way, and RPC authentication is not bypassed. The early return is Dash-specific (added in 78c5ca5, blocked in 0.12.1, reintroduced by ff5540b in 0.16.0.0). Bitcoin Core decrypts the master key on every `Unlock`. ## What was done? - Removed the early return. Every request on an encrypted wallet now derives the key from the passphrase and decrypts the master key, as Bitcoin Core does. - When a master key is already held (full or mixing-only unlock), the decrypted candidate must match it, compared with `TimingResistantEqual`. A mismatch moves on to the next master-key entry. - This matters because the already-unlocked path skips `CheckDecryptionKey`, and a blank wallet passes that check trivially. Without the comparison, a wrong passphrase that happens to produce valid padding would still be accepted. - An authenticated request on a fully unlocked wallet is a no-op success. The metadata and descriptor-cache upgrades are not repeated. - The mixing-only → full upgrade path is unchanged, and so are the RPC timer logic, full → mixing rejection and the unencrypted-wallet result. ## How Has This Been Tested? macOS arm64, depends build. - **Regression test.** `wallet_encryption.py` now ends with one deterministic check under the mocktime the test already sets: with the wallet fully unlocked for 100 seconds, `walletpassphrase` with a wrong passphrase and a 1000-second timeout fails with `-14`, and `unlocked_until` does not change. Against an unpatched `wallet.cpp` the check fails ("No exception raised"). With the fix it passes. - `wallet_encryption.py --legacy-wallet` and `wallet_encryption.py --descriptors` both pass. - `test_dash --run_test=bip39_tests,wallet_crypto_tests` passes, and `lint-python.py` is clean. - All `Unlock(SecureString)` callers were checked: Qt unlock dialog and wallet controller, createwallet, EncryptWallet, migration and upgradetohd. Limits: - The valid-padding mismatch guard was reviewed in the source, not fault-injected. A wrong passphrase gets past decrypt padding only about 1 in 256 times, so a functional test cannot exercise the guard deterministically. - A *locked* blank encrypted wallet still accepts about 1 in 256 wrong passphrases. That gap already existed and Bitcoin Core has it too. Closing it needs a stored key check, so it is out of scope here. ## Breaking Changes None. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

…as repair errors 581a219 fix(evo): treat missing snapshots during evodb repair as repair errors (pasta) Pull request description: ## Issue being fixed or feature implemented When the evodb is missing a masternode list snapshot record, the automatic evodb verify/repair at startup (added in dashpay#6999) does not fail. It logs a warning, reports success and marks the database as repaired, so the check never runs again. `RecalculateAndRepairDiffs` treats a missing snapshot as unrecoverable. It stops processing and emits `CRITICAL: Snapshot missing at height N. This cannot be repaired by this tool - full reindex required.` That message goes into `verification_errors`, not `repair_errors`. The startup caller only treats `repair_errors` as fatal, so for a missing snapshot it: - prints `WARNING: Verification errors:` and then `Successfully repaired 0 masternode list diffs`; - calls `CompleteRepair()`, which sets `DB_LIST_REPAIRED`, so every later start logs `Masternode list diffs are already repaired` and skips the check, unless the debug-only `-forceevodbrepair` is passed; - discards any diffs it already recalculated for earlier snapshot pairs, because of the early return, and never checks the pairs after the missing snapshot. The `evodb repair` RPC has the same problem. It returns an empty `repairErrors` array, although the help text defines a non-empty `repairErrors` as "full reindex required". This only affects nodes whose own evodb is already missing a snapshot record. ### Why this is a real problem Code path at c14104b: - A missing `from` snapshot (except the initial DIP0003 one) and a missing `to` snapshot are both pushed to `verification_errors`, followed by `return result;` before `WriteRepairedDiffs`: [deterministicmns.cpp#L1245-L1266](https://github.com/dashpay/dash/blob/c14104b172a2/src/evo/deterministicmns.cpp#L1245-L1266), [#L1290-L1293](https://github.com/dashpay/dash/blob/c14104b172a2/src/evo/deterministicmns.cpp#L1290-L1293) - Startup only logs `verification_errors`, shuts down only on `repair_errors`, and otherwise calls `CompleteRepair()`: [init.cpp#L2517-L2533](https://github.com/dashpay/dash/blob/c14104b172a2/src/init.cpp#L2517-L2533) - `CompleteRepair()` persists `DB_LIST_REPAIRED`, and once it is set startup skips the check: [deterministicmns.cpp#L1298-L1310](https://github.com/dashpay/dash/blob/c14104b172a2/src/evo/deterministicmns.cpp#L1298-L1310), [init.cpp#L2491](https://github.com/dashpay/dash/blob/c14104b172a2/src/init.cpp#L2491) - RPC contract for `repairErrors`: [rpc/evo.cpp#L2132](https://github.com/dashpay/dash/blob/c14104b172a2/src/rpc/evo.cpp#L2132) End-to-end reproduction on regtest. I mined 1200 blocks, so snapshots exist at heights 432, 576 and 1152. I stopped the node, deleted the `("dmn_S3", <hash of block 576>)` record from `evodb` with a small leveldb tool, then restarted twice. <details> <summary>Reproduction with a <code>dashd</code> built from c14104b (unfixed)</summary> ``` == [unfixed] mine 1200 regtest blocks (snapshots at DIP0003 height 432, 576 and 1152) tip height: 1200 block 576: 0aa9baa5c36d2f2f357c320bc33c7893677b60681fc2d3dae17faa0705bbc917 == [unfixed] remove the masternode list snapshot record at height 576 from evodb snapshot record existed=1 (41 bytes), delete=OK == [unfixed] restart #1 (startup evodb verify/repair runs) node state after restart #1: RUNNING Verifying and repairing masternode list diffs...

When it hits a missing snapshot, the operator is told the repair succeeded, the database is marked as repaired, and the check is turned off for later starts. Diffs before the missing snapshot that the repair already found to be bad stay bad on disk, and nothing after it is checked. The node keeps running on evodb data the repair itself rated "full reindex required". Other nodes are not affected. ## What was done? In `RecalculateAndRepairDiffs`, both missing-snapshot errors go into `repair_errors` when `repair` is true, and into `verification_errors` as before when `repair` is false. The message text is unchanged. The existing startup path then does what it already does for other unrecoverable repair failures. It logs `Failed to repair masternode list diffs. Database corruption detected. Please restart with -reindex to rebuild the database.` with the error, calls `StartShutdown()`, and returns without calling `CompleteRepair()`. `evodb repair` reports the error under `repairErrors`, and `evodb verify` still reports it under `verificationErrors`. Added a regression test, `evodb_repair_missing_snapshot_is_repair_error`, to `src/test/evo_deterministicmns_tests.cpp`. It mines past two snapshot periods and first checks that the intact range verifies without errors. It then erases the snapshot record at height 576 and checks that repair mode reports it in `repair_errors`, both when the missing snapshot ends a pair and when it starts one. Finally it checks that verify-only mode still reports it in `verification_errors`. ### Why this is the correct minimal fix The root cause is that this condition was put in the wrong error category. Everywhere else in this function, an error that means "cannot repair, full reindex required" goes into `repair_errors`, which is what both callers act on. Moving the error there reuses the existing startup handling and the documented RPC contract, so `init.cpp`, the RPC code and `RecalcDiffsResult` need no change. Alternatives considered: - Skipping `CompleteRepair()` while letting the node keep running would also need a separate signal, either a new result field or a check in init. It would also rerun a check that cannot succeed on every start without telling the operator what to do. - Writing the diffs already recalculated before returning would not help. The snapshot still can't be rebuilt, and the operator still has to reindex. Intentionally unchanged: - The other early returns (`Stop height ... below DIP0003`, `Could not find starting snapshot`, `Need at least 2 snapshots`) stay in `verification_errors`. They are normal on short chains. - A missing initial snapshot at the DIP0003 height is still replaced by an empty list, as before. ## How Has This Been Tested? macOS arm64, `--enable-debug --enable-werror`, depends build. - `src/test/test_dash --run_test=evo_dip3_activation_tests/evodb_repair_missing_snapshot_is_repair_error`: fails without the fix (output above) and passes with it. - `src/test/test_dash --run_test=evo_dip3_activation_tests`: all 41 test cases pass with the fix. - I re-ran the regtest reproduction above with a `dashd` built with this change. <details> <summary>Same reproduction with this change</summary> ``` == [fixed] restart #1 (startup evodb verify/repair runs) node state after restart #1: NOT RUNNING Verifying and repairing masternode list diffs...

Previously it kept running and marked the evodb as repaired. `evodb repair` now reports this condition in `repairErrors` instead of `verificationErrors`. Healthy nodes are unaffected. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

…ilures 973f59e fix: relock encrypted wallets after HD upgrade failures (pasta) Pull request description: ## Issue being fixed or feature implemented An encrypted wallet temporarily unlocked by `upgradetohd` remained fully unlocked when mnemonic validation or later HD setup threw. An already authenticated caller with signing/spending permissions could then use existing keys until another lock event. This does not bypass RPC authentication. ## What was done? Install the existing cleanup handler before the temporary unlock and relock on every subsequent exit, including success, while the wallet locks are still held. Keep early validation behavior and relock before any rescan. ## How Has This Been Tested? On macOS arm64 with prebuilt depends, built baseline and candidate with `make -j1`. The added regression fails on the baseline in both legacy and descriptor modes because signing succeeds after a rejected upgrade. Full `wallet_upgradetohd.py --legacy-wallet` and `--descriptors` pass with the fix, covering signing denial after invalid mnemonic, legacy overlength passphrase and successful upgrade, plus verified signatures after explicit unlock. Existing recovery/rescan tests remain covered by those full runs. Ran `test_dash --run_test=bip39_tests,wallet_crypto_tests`, changed-file Python lint using the repository's enabled rules, and `git diff --check`. An independent four-pass review approved the final source and inspected the reproduced baseline evidence; its remaining cache/test suggestions were resolved by the complete reruns. No fund movement or RPC authentication bypass was demonstrated. ## Breaking Changes None. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone This pull request was created by Codex.

9178483 fix: validate Electrum import input boundaries (pasta) Pull request description: ## Issue being fixed or feature implemented `importelectrumwallet` reads an exact-sized JSON file allocation through UniValue's pointer-only parser, which determines length using `strlen`. A full read supplies no terminator. It also accepts negative rescan indices, imports keys and then passes the negative height to an exact chain lookup that aborts the node. Both paths require an authorized RPC caller, a readable local export and an unlocked legacy wallet. Method-limited deployments make the negative-index abort relevant beyond an administrator's existing ability to stop a node. ## What was done? Use a binary, length-managed string for JSON input, validate file size/read errors, resize to the actual byte count and invoke the bounded parser overload. The string also supplies the parser's sentinel. Reject a negative rescan index before processing the export or installing keys; preserve the existing clamp for indices above the tip and document the non-negative argument. Extend `wallet_dump.py` to reject a valid JSON prefix followed by embedded NUL/trailing bytes, check negative indices for JSON and CSV without importing keys, and retain valid bare/p2pkh-prefixed WIF imports at zero, tip and above-tip indices. Verify the imported private keys through dump/sign/verify RPCs and unload the temporary wallets before the existing dumpwallet scenarios. ## How Has This Been Tested? On macOS arm64 with BDB and SQLite enabled: full `make -j1`, the complete `wallet_dump.py --legacy-wallet --portseed=1`, a separate negative-index node-liveness regression (both serially at TEST_RUNNER_PORT_MIN=12000), 31 wallet/walletdb unit cases, and both UniValue object/data test executables passed. Python lint with the repository selection, assertion/include/whitespace lints and `git diff --check` passed. The UniValue data executable requires `src` as its working directory; an initial root-directory invocation failed to find its fixtures and the corrected invocation passed. Independent four-pass review found no blocking source defects; the final transferred patch exactly matches the reviewed file/diff hashes. Baseline defensive RPC regressions accepted the embedded-NUL JSON prefix, and a separate disposable regtest negative-index RPC terminated the node at the production `getBlockHash` assertion. The earlier isolated actual-UniValue ASan proof demonstrates the allocation/parser primitive, not a full-daemon disclosure or code-execution outcome. No deployed restricted account or production crash probability was measured. Stream-error injection, concurrent file modification and exact rescan-start observation were not tested. ## Breaking Changes Negative rescan indices now return RPC_INVALID_PARAMETER before import. JSON bytes after an embedded NUL are parsed and rejected instead of silently ignored. Valid export formats and the above-tip clamp remain supported. ## Checklist: - [x] I have performed a self-review of my own code - [x] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone This pull request was created by Codex.

…t data 2226682 fix: return REST errors for unavailable deployment data (pasta) Pull request description: ## Issue being fixed or feature implemented REST deployment queries call the deployment RPC directly. When EHF reconstruction needs an unavailable block body, its exception can escape the HTTP worker. This requires REST to be enabled and the client to pass the HTTP address ACL; REST is disabled by default. ## What was done? Translate deployment RPC exceptions into a plain-text HTTP 500 response before writing successful response headers. Valid requests retain the existing JSON response. The change leaves deployment rules and reconstruction unchanged. ## How Has This Been Tested? On macOS arm64 with prebuilt depends: `make -j1`, `test_dash --run_test=rpc_tests`, `interface_rest.py` with an isolated port range, selected Python lint, whitespace lint, circular-dependency lint, and `git diff --check` passed. The functional test requests a known post-V20 header without its body, checks the error and continued RPC/REST responses, then supplies the body and checks the successful response. The first runner attempt failed during cache startup because an HTTP port was occupied; the isolated retry passed. Independent final four-pass review completed. No pre-fix daemon termination or external exposure demonstration was performed, and the test is not claimed as a before/after crash reproduction. ## Breaking Changes Unavailable deployment reconstruction returns HTTP 500 instead of allowing an exception to escape the callback. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone This pull request was created by Codex.

…ssphrases 6861fa5 fix: preserve wallet permissions when changing passphrases (pasta) Pull request description: ## Issue being fixed or feature implemented A successful `walletpassphrasechange` during a CoinJoin mixing-only unlock silently left the wallet fully unlocked. An already authenticated caller with signing/spending/export permission could use keys beyond the owner's prior mixing restriction. This does not bypass RPC authentication, and the existing unlock timer still bounds the interval. ## What was done? Capture the original locked/mixing mode under the wallet's existing locks. Unlock a mixing-only wallet as mixing-only so it stays that way, and relock wallets that started locked on every exit path via a cleanup handler. Successful maintenance preserves full unlock where it was already allowed; incorrect-old-passphrase behavior, encryption format and unlock timers remain unchanged. ## How Has This Been Tested? Built on macOS arm64 with prebuilt depends. The added regression fails against baseline in both wallet backends because signing succeeds after changing a mixing-only wallet's passphrase. `wallet_encryption.py --legacy-wallet` and `--descriptors` pass with the fix. The regression runs a locked/mixing/full input table: after `walletpassphrasechange`, it checks `signmessage` (with signature verification) and `coinjoin start`/`stop` authorization for each mode.

…ed chainstate BACKPORT NOTE: - The last flushed block is recorded right after the coins flush; Dash then commits EvoDB in the same flush before ChainStateFlushed is sent. - The skip message gets Dash's explicit trailing newline; Commit() keeps Dash's LogError form. - src/test/chainstate_write_tests.cpp does not exist in Dash, so its two assertions are not applied. - baseindex_tests: Init() and Sync() are not callable on their own in Dash (bitcoin#27607, bitcoin#28955 are not backported), so the test starts the index and holds back the sync thread with g_indexes_ready_to_sync to read the committed best block. ---- e9ed898 validation: Don't use m_chain.Tip() in FlushStateToDisk (Martin Zumsande) 3679f1e index: Don't commit ahead of the flushed chainstate (Martin Zumsande) 6573572 index: Remove return value from Commit() (Martin Zumsande) 09c0696 validation: track last flushed block (Martin Zumsande) 13c02b5 test: add test for index commits ahead of the last flushed block (Martin Zumsande) Pull request description: If indexes commit their data ahead of the flushed chainstate, and there is an unclean shutdown, the index will be corrupted. This is especially the case for the coinstatsindex, which has state (the muhash) which can't easily be rolled back without access to the blocks. This was only partly fixed in bitcoin#33212 (for reorg scenarios) but could still happen during initial sync. Fix this more thoroughly by having the node keep track of the last flushed block, and skipping index commits if the current block of the index is not an ancestor of the node's last flushed block (similar to the suggestion by stickies-v in bitcoin#33212 (review).

…block BACKPORT NOTE: - feature_pruning.py on v24.0.x syncs node 5 inside wallet_test(); the new pruned restart of node 0 would leave node 5 with only a limited peer, so node 5 is synced to node 0 before it, as on develop. - Pruned v24.0.x nodes disable governance and log a warning on stderr, so test_rescan_blockchain() now expects it when it restarts the already pruned node 0. 9b22995 indexes: set prune lock to genesis before first block (Andrew Toth) 0ae3b40 test: characterize startup with newly added prune and index (Andrew Toth) Pull request description: When setting both a new index and prune size and restarting an unpruned node, the node will prune the block store first and then the index will fail to start syncing. Fix this by setting the prune lock to 0 if the index does not yet have a best block.

BACKPORT NOTE: - v24.0.x has no GovCollateralIndex, so its CustomRewind hunk is not applied. The address, spent, timestamp and governance collateral indexes erase the entries of rewound blocks in CustomRewind. Upstream indexes keep nothing a rewind has to undo, so bitcoin#33212 could stop committing in Rewind and bitcoin#34897 could leave the locator where it is until the chainstate has flushed past the new tip. With erasures persisted right away, a locator that stays above them is wrong after an unclean restart: if the rewound branch wins again, Init() resumes from the old locator and the erased blocks are never indexed again. The governance collateral index used to write the rewound locator unconditionally, which keeps bitcoin#33208 (a locator naming a block that is not in the on-disk block index) for an index that is always on. When the committed locator is above the new tip on the same branch, move it to the new tip in the rewind's own batch. The committed tip was an ancestor of a flushed block when it was written, so the new tip below it is in the on-disk block index after a restart. A committed locator at or below the new tip needs no change: a restart re-appends from it. The new baseindex_tests scenario uses a test index that erases on rewind the way the Dash indexes do: it rewinds past the last flush, restarts and must index the erased blocks again. It fails with WriteRewindLocator as a no-op. Co-authored-by: pasta <pasta@dashboost.org>

…cator The address and spent indexes wrote each rewound block's erasures in a batch of their own, and the timestamp index erased entry by entry, before the rewind's locator went out in a final, separate batch. A node that stops between those writes keeps a locator naming a block whose entries are gone. Its next start resumes past that block and never indexes it again. BaseIndex::RewindBlockByBlock() now walks the rewound blocks and writes each block's erasures in the same batch as the locator moved to its parent, so an interrupted rewind leaves the locator at the highest block still indexed. The address and spent indexes use it. The timestamp index needs no block reads, so it erases everything and moves the locator in one batch, like the governance collateral index already did. The new baseindex_tests scenario stops a rewind after its first block and restarts: the locator must name the block below and the erased block must be indexed again. With the erasures and the locator in separate batches it fails both checks. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

BACKPORT NOTE: - v24.0.x has no GovCollateralIndex, so its WritesEagerly() override is not applied. Dash's address, spent, timestamp and governance collateral indexes write a block's entries as soon as they append it. Since bitcoin#34897, Commit() skips the locator for a tip above the last flushed block, so a sync that ends above the flush leaves entries on disk for blocks the locator doesn't cover. If the node stops uncleanly and those blocks, already durable in the block index, are reorged away before the index syncs again, Init() resumes from the older locator and never rewinds them: the address index keeps the orphaned payment in the history and the unspent outputs. Before bitcoin#34897 the end-of-sync commit wrote the tip and the restart rewound it. For these indexes a skipped commit now records the index tip under its own key, and a successful commit erases it in the same batch as the locator. Rewinds move it down with the locator. Init() resumes from it when the block index has it above the locator, so the sync rewinds it if it left the active chain, and drops it otherwise. The locator keeps the upstream meaning, so a locator naming a block the block index lost is still a startup error, and a recorded tip the block index lost falls back to the locator as before. Blocks appended through BlockConnected after the sync are not covered: their locator also waits for the next flush, as it did before bitcoin#34897.

BACKPORT NOTE: - v24.0.x has no GovCollateralIndex, so the CanSync() change and its governance_collateral_tests case are not applied. The base.{h,cpp} part (ResumeBlock(), used by Init()) is kept so that Init() has develop's shape; on v24.0.x it changes no behavior beyond dropping an uncommitted tip equal to the locator, from which Init() resumes the same way. GovCollateralIndex::CanSync() decides at startup whether the always-on governance collateral index can sync, by checking block data from the active-chain fork of its committed locator up to the tip. BaseIndex::Init() now resumes from the uncommitted tip when the block index has it above the locator. Pruning follows the index's in-memory tip, so blocks between the two can be gone after an unclean stop, and the check then disabled governance even though the index could resume. BaseIndex::ResumeBlock() now picks the block Init() resumes from, and CanSync() checks only the blocks above its active-chain fork. When the block index lacks the locator's block, Init() fails before looking at the uncommitted tip, so CanSync() keeps checking from the locator then. Init() now also drops an uncommitted tip equal to the locator, which it used to keep; it resumes from the same block either way. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

An eager index persists each block's entries as it appends it, and a Commit() skipped above the last flush records the index tip instead of the locator. An unclean stop can then lose the blocks above the flush from the block index while their entries stay on disk. Init() dropped the unknown tip and resumed from the older locator, so the index reported itself synced with entries for blocks the node no longer knows, which it can neither check against the active chain nor rewind. Fail with a rebuild instruction instead, as startup did before the commit guard, when the end-of-sync locator named the lost block. An uncommitted tip the block index has but that isn't above the locator is still dropped. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…egacy data On a datadir upgraded from v23, the legacy "addressindex", "spentindex" and "timestampindex" flags in the block index database stay set after the first v24 start has moved the legacy entries into indexes/. If the index directories are later deleted to rebuild them, the next start finds nothing to migrate, but MigrateOldIndexData() still finalizes the empty database with the chainstate tip. The index then reports itself synced while every query returns nothing (zero balances, no txids, no block hashes), and the same would happen to a rebuild that was interrupted before its first commit. Only finalize a target that actually holds migrated entries, and clear each enabled index's legacy flag once its migration step has run, since the legacy entries no longer exist. A deleted or partially rebuilt index is now rebuilt from genesis. Older versions see the cleared flag and ask for the -reindex that the release notes already require after a downgrade, instead of serving the erased synchronous index.

… from it A node that runs without -addressindex across a reorg and then enables it again must rewind the index past the orphaned blocks instead of keeping their entries. Before bitcoin#25193 (8588588) the index resumed from the fork point of its locator and never removed them. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

bitcoin#25193 lets -reindex-chainstate run with optional indexes enabled and removed "Deactivate all optional indexes before running this." from the option's help text. Update the dashd and dash-qt man pages to match. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…se notes Fold doc/release-notes-8018.md and doc/release-notes-8029.md into the consolidated release notes and remove them: - dashpay#8018: the IPv4-primary and mainnet standard-port rules go under Extended addresses, with a pointer from the masternode upgrade notes. Mainnet keeps requiring them; testnet and devnets allow other primaries from height 0. - dashpay#8029: dashd no longer creates an empty dash.conf, under Updated settings. This also settles the pending note on starting without an existing default data directory, so that TODO is removed. Describe the index fixes carried from dashpay#8033: the one-time rebuild for nodes that ran a release candidate (replacing the release-candidate TODO), the -reindex-chainstate change from bitcoin#25193, older versions refusing a migrated index until -reindex, and the known limitation shared with earlier versions. The other rc.7 picks fix code that is new in v24 and need no release note. No man page changes: the only help text change, the ipv4_optional name in -testactivationheight, is debug-only.

The bitcoin#33212/bitcoin#34897 and locator commits from dashpay#8033 are replaced by the v24.0.x port of dashpay#8042 (merge 9e5e3d5), ported commit by commit, so the index paragraph now cites dashpay#8042 and dashpay#8031 instead of dashpay#8033. dashpay#8031 is cited for older versions refusing a migrated index, and bitcoin#25193 alone for -reindex-chainstate. dashpay#8042 also makes startup fail with "<index>: the block the index was last synced to is not found. Please rebuild the index." when an unclean shutdown loses blocks whose entries an index had already written. Mention that error next to the known limitation, which still applies in the other cases.

A masternode upgrading from v23.1.10 to v24.0.0 would lose them. Also, `check_merge` requires `master` to fast-forward to `v24.0.x`, which fails until v23.1.10 is recorded here. ## What was done? This is not a merge of the v23 branch. Each v23.1.10 commit was checked by content against `v24.0.x`, and none of the eight code commits were present. They are picked here with `git cherry-pick -x` from `v23.1.x`, in release order: - `fix(llmq): drop DKG members whose verification vectors share coefficients` (c8627a6). Clean. - `test: cover DKG members dealing identical contributions` (1ec6aaa). The new `feature_llmq_simplepose.py` case runs right after the sporks are set, in both spork23 modes as in v23, with numeric `dkgsimerror` rates. The simulated clone in `active/dkgsession.cpp` uses this branch's `util::irange` (`util/helpers.h`). - `fix(llmq): accept equal DKG secret key shares when aggregating a member's share` (dfd9820). The new `bls_tests` case passes `CBLSWorker::Start(4)`, because `Start()` takes an explicit worker count here. - `fix(governance): don't vote NO-FUNDING on triggers before their maturity window` (5d9fe74) and `fix(governance): don't vote on triggers while not synced` (bd948aa). Clean. - `fix(bls): weight batch-verified signatures so complementary errors cannot cancel` (593f252). `BatchVerifyMessageSigs` lives in `src/llmq/net_dkg.cpp` on this branch, so its hunk is applied there unchanged. - `fix(llmq): weight batched DKG contribution verification` (12bbd21). The new `bls_tests` loop uses `util::irange`. - `fix(bls): stop weighted contribution batch verification on an invalid partial aggregate` (95fbf22). Clean. Each adaptation is described in its commit message. They are the same as in the develop merge-back, dashpay#8015. The files these fixes touch are identical on `develop` and `v24.0.x`, apart from two unrelated lines. Not picked: - `fix(instantsend): propagate !cs_timingsTxSeen to the callers of RemoveNonLockedTx` (3174d5f). It fixes a clang `-Werror` break that exists only on v23.1.x. The methods it annotates don't exist on this branch, which builds cleanly with `-Werror` and `-Wthread-safety`. - Release bookkeeping (01dc7e0): the version, the v23.1.10 release notes file, man pages and flatpak entry stay with v24's own release process. Its operator-relevant content is covered in the v24.0.0 notes (see below). ### Merge of v23.1.10 The last commit merges the `v23.1.10` tag with the tree unchanged (`-s ours`), as dashpay#7965 did for v23.1.9. That lets `master` fast-forward to `v24.0.x`, and the final v24.0.0 contains every v23.1.10 commit. A trial real merge on top of the picks staged no clean additions. Everything else it produced was release bookkeeping or conflicts re-inserting code the picks already carry. ### Release notes The v24.0.0 notes include only what a v24 operator needs to act on or plan for: required action, configuration, compatibility, upgrade behaviour and changed operational expectations. They no longer carry patch releases forward one by one. I checked the v23.1.1 to v23.1.10 notes against that rule. Two doc commits follow the merge: - The v23.1.9 carry-forward bullet is replaced by a standalone note that provider transactions are no longer InstantSend-locked, with the advice to wait for a ChainLock or confirmations instead (dashpay#7858). - Added under their v24 topics: - Asset Locks with more than 100 inputs or larger than 20480 bytes are non-standard (dashpay#7359). - `-allowprivatenet` no longer affects masternode address validation (dashpay#7888). - A DKG member sharing verification-vector coefficients with another is excluded together with it, and both get the usual PoSe penalty. Routine bug, crash and DoS fixes, GUI, build and performance changes, and fixes that need no operator action (including the superblock trigger voting fix, the negative-`nVersion` rule and the extra work of weighted BLS batch verification, for which no node-wide CPU impact has been measured) are left out. The archived v23.1.10 notes, the older-releases list and the change-log link stay with v24.0.0 release preparation. No version change is needed. `configure.ac` stays at 24.0.0 with `CLIENT_VERSION_IS_RELEASE` false. ## How Has This Been Tested? macOS arm64 against depends, `--enable-debug --enable-werror --disable-hardening --without-gui`. `dashd`, `test_dash` and `bench_dash` build cleanly at the tip. `dashd` and `test_dash` also build at every pick. - Unit suites, all passing: `bls_tests`, `llmq_dkg_tests`, `llmq_utils_tests`, `governance_inv_tests`, `governance_validators_tests`. - Functional tests, all passing: `feature_governance.py` (with the new early-trigger case), `feature_governance_cl.py`, `feature_llmq_simplepose.py` (default and `--disable-spork23`, both with the new cloned-contribution case), `feature_llmq_dkgerrors.py`, `feature_llmq_signing.py` (default and `--spork21`), `feature_llmq_data_recovery.py`, `feature_llmq_rotation.py`. - Every file the release touches was compared with `v23.1.9..v23.1.10`, and each carries the same added and removed lines. The only exceptions are the adaptations listed above and the skipped instantsend commit. I did not run the full functional suite locally; CI covers it. ## Breaking Changes None. These are not consensus changes. ## Checklist: - [x] I have performed a self-review of my own code - [x] I have made corresponding changes to the documentation - [x] I have assigned this pull request to a milestone _(if you have permission to set one)_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

Its `test_conflict_txs` migrates through `self.migrate_wallet`, as on develop since bitcoin#28868. - dashpay#8014 backport: bitcoin#28609, bitcoin#34215, bitcoin#34226, bitcoin#34370, partials bitcoin#31423, bitcoin#34156 (migratewallet fixes from 28.x), with the Dash adaptations below - dashpay#8037 docs: list the config file path each Linux init system uses - dashpay#8029 fix: let dashd -version, -help and first start work without an existing data directory - dashpay#8032 fix(qt): don't offer a new operator key when reopening a shared masternode session - dashpay#8035 fix(qt): don't strand coins reserved for a shared masternode session - dashpay#8027 fix(qt): fund a shared masternode's service update from this wallet by default - dashpay#8034 fix(qt): check a shared masternode's service and refund addresses before coins are reserved - dashpay#8021 fix(qt): don't load a newer shared masternode session copy that changes your own share - dashpay#8024 fix(qt): keep the shared masternode dissolve dialog consistent with what it will send - dashpay#8020 fix(rpc): make protx shared_sign sign only dissolutions that return every principal. Its `doc/release-notes-7437.md` sentence goes into the same paragraph of `doc/release-notes.md`, since that file was folded in for v24.0.0. - dashpay#8026 fix(qt): keep shared masternode contribution fields locked while coins are reserved (merged on develop as cc73a04; GitHub shows the PR as closed) - dashpay#8018 fix(consensus): require IPv4 masternode primaries until IPv4 is optional, pin mainnet ports, with the adaptation below - dashpay#8036 fix(qt): let a shared masternode participant follow a revised invitation that keeps their share - dashpay#8045 test: scale the mempool-loaded wait by timeout_factor so TSAN reindex restarts stop timing out ### Index fixes: dashpay#8042 port and dashpay#8033 The index commits are dashpay#8042 (merge 9e5e3d5), ported commit by commit to `v24.0.x`, plus the parts of dashpay#8033 that dashpay#8042 doesn't cover. dashpay#8042's v24.0.x port replaces dashpay#8033's bitcoin#33212, bitcoin#34897 and rewind-locator commits, and dashpay#8033's flushed-block announcement fix (e6a687b) is dropped: bitcoin#30221 removes the wallet's `ChainStateFlushed` locator write, and nothing else on `v24.0.x` consumes that notification. This PR replaces dashpay#8033, and dashpay#8031 comes in through it (adapted to the `v24.0.x` `CCoinsViewDB` constructor), not as a separate pick. - bitcoin#25193 (from dashpay#7883, via dashpay#8033): indexes: read the locator's top block during init, allow interaction with `-reindex-chainstate` - From dashpay#8042: partial bitcoin#32069 (only `TestNode.kill_process()`, with develop's `wait_until_stopped(**kwargs)` handling it needs), partial bitcoin#30221, partial bitcoin#32580, bitcoin#32878, bitcoin#33212, bitcoin#32882, bitcoin#32875, partial bitcoin#34897, bitcoin#36150, and dashpay#8042's own fixes: move the committed locator below the entries a rewind erases; write a rewound block's erasures in one batch with its locator; resume from the tip a skipped commit leaves behind; check the blocks an index resumes from at startup; reject an uncommitted tip the block index lost - From dashpay#8033: dashpay#8031 fix(index): don't adopt an empty or rebuilt async index as migrated legacy data; test: blocks orphaned while the address index is disabled are removed from it; docs: drop the index caveat from the `-reindex-chainstate` man page entry #### Dash adaptations for dashpay#8042 - The governance collateral index doesn't exist on `v24.0.x`, so its hunks are dropped; from the startup resume check only the `base.{h,cpp}` part is kept. - `feature_pruning.py`: node 5 syncs before node 0's pruned restart, and `test_rescan_blockchain` expects the governance-disabled stderr a pruned node prints on `v24.0.x`. - The wallet's `blockConnected` has no birthday skip on `v24.0.x`. - `TestNode.wait_until_stopped()` keeps `v24.0.x`'s `None` default for a clean exit. Apart from these, the `v24.0.x` index, validation and index test sources differ from develop after dashpay#8042 only by differences that already existed before it. #### Dash adaptations for dashpay#8018 `v24.0.x` predates bitcoin#26177, so it has no `src/kernel/chainparams.cpp` and no `GetBuriedDeployment()`. The four `IPv4OptionalHeight` values (mainnet not scheduled, testnet 0, devnet 0, regtest only through `-testactivationheight=ipv4_optional@<height>`) go into the matching classes in `src/chainparams.cpp`, and `ipv4_optional` is parsed in its `MaybeUpdateHeights()`. The `GetBuriedDeployment()` hunk is dropped; the `DeploymentName()` case is kept. Every other file, including all tests, changes exactly the same lines as the develop merge. The same notes are in the pick's commit message. #### Dash adaptations for dashpay#8014 dashpay#8014 doesn't cherry-pick cleanly onto `v24.0.x`. The conflicts were resolved against `v24.0.x` APIs. No prerequisite was backported, and no hunk or test was dropped. The same notes are in the pick's commit message. - `src/wallet/bdb.{cpp,h}`, `dump.cpp`, `sqlite.{cpp,h}`, `transaction.{cpp,h}`, `wallet.cpp`: the changed lines are identical to the develop merge. In `wallet.cpp`, the conflict was with develop-only context (`CanGrindR`), which stays out. - `src/wallet/db.h`: dashpay#8014 makes `WalletDatabase::Files()` pure virtual. `v24.0.x` still defines `DummyDatabase` in `db.h`, so it gets the `Files()` override there. - `src/wallet/test/wallet_tests.cpp`: the test database mock on `v24.0.x` is `FailDatabase`, so it gets the same `Files()` override. `src/wallet/salvage.cpp` and `src/wallet/test/util.h` keep the `v24.0.x` side, since develop's `DummyDatabase`/`MockableDatabase` placement doesn't exist here. - `test/functional/tool_wallet.py`, `wallet_backup.py`, `wallet_migration.py`: the test framework on `v24.0.x` has no `TestNode.wallets_path`/`datadir_path` (bitcoin#27884), so the new tests build these paths with `os.path.join` and pass RPC paths as strings. `wallet_migration.py` takes only dashpay#8014's new tests, not the develop-only tests around them. - `test/functional/wallet_migration.py`: `unsynced_wallet_on_pruned_node_fails` stops its pruned node with `EXPECTED_STDERR_NO_GOV_PRUNE`, because on `v24.0.x` a pruned node still prints the governance-disabled warning. The rc.6 picks handled the same warning the same way. ### Separate v24.0.x PRs, merged separately - dashpay#8016 backport: v23.1.10 fixes for v24.0.x - dashpay#8022 backport: bind CoinJoin signatures to the approved transaction (dashpay#7815) for v24.0.x, which depends on dashpay#7815 merging on develop dashpay#8016 and dashpay#8022 each merge cleanly with this branch in either order, and all three merge to the same tree in any order. ### Not picked - dashpay#8025: closed; superseded by dashpay#8014 (picked above) - dashpay#8031 is not picked separately; it comes through dashpay#8033's commits above. - dashpay#8039, dashpay#8040, dashpay#8041, dashpay#8043, dashpay#8044 (CI and tooling), dashpay#7905, follow-ups to dashpay#8042, and the PRs in the 24.1 milestone. - Explicitly deferred: dashpay#7870, dashpay#7679, dashpay#7675, dashpay#7220, dashpay#7217, dashpay#7109, dashpay#6988, dashpay#4974, dashpay#8028. ### Release notes `doc/release-notes.md` corrections, checked against the code on this branch: - **Version 2 Asset Unlocks:** version 1 Asset Unlocks stay valid after `v24` activation. Platform withdrawals keep using version 1 until a future Dash Platform release issues version 2, so the stable txid, InstantSend locking and instance-hash relay don't apply to them yet. - **Masternode requirements:** the startup refusals (dashpay#7754) and the DKG bad votes for missing transaction relay or compact filters (dashpay#7755) apply from the first start of v24.0.0, not from activation. Operators should remove conflicting settings and upgrade before the `v24` start date (November 9, 2026), so their masternodes are running when the activation signal is signed. `-peerblockfilters=0` is the new refusal; `-blockfilterindex=0` already failed on v23. - **How to Upgrade:** a pruned node with `-addressindex` or `-spentindex` now refuses to start; v23 accepted that combination. - **Downgrading:** there is no supported downgrade after `v24` activation: older versions can't follow the network, and they misread the masternode list data v24.0.0 writes. Before activation, downgrading to v23.1.x works with the listed caveats. Dash-Qt's dust-protection setting is migrated to the shared settings, so it reads as disabled after a downgrade. - **Dash Platform:** Platform/dashmate v5.0.0 and later handle the hidden `service` and `softforks` RPC fields. Older Platform versions need both `-deprecatedrpc` options. - **Compatibility:** users on macOS 13 or older must upgrade macOS, or move their node, before activation. - **Legacy wallets:** in v24, `createwallet` with `descriptors=false` also needs `load_on_startup`; before v24 this applied only to `descriptors=true`. The notes now give a working example. - **Wallet migration (dashpay#8014):** failure handling in `migratewallet`, `restorewallet` and `dash-wallet createfromdump` is fixed, and the new backup and watch-only/solvables wallet names are listed. - **Ecosystem notes:** the txid of a version 2 Asset Unlock zeroes `requestedHeight`, `quorumHash` and `quorumSig` before hashing (the full-bytes hash is `instanceHash`); pools should emit one coinbase output per `masternode[]` and `superblock[]` template entry, since merged or deduplicated payees are invalid after activation; client libraries that send numbers or booleans as strings fail (dashpay#7099); and some wallet RPC error messages changed with upstream backports. - **rc.7 picks:** `doc/release-notes-8018.md` and `doc/release-notes-8029.md` are folded in and removed. dashpay#8018's IPv4-primary and mainnet standard-port rules are under Extended addresses, with a pointer from the masternode upgrade notes; dashpay#8029's `dash.conf` change is under Updated settings. The other rc.7 picks fix code that is new in v24 and need no release note. - **Index fixes (dashpay#8042, dashpay#8031):** nodes that ran a release candidate with the address, spent or timestamp index should rebuild them once (with `-reindex`, or by starting once with them disabled, deleting their `indexes/` directories and starting with them enabled). The notes also cover `-reindex-chainstate` with indexes enabled, older versions refusing a migrated index until `-reindex`, the new "the block the index was last synced to is not found. Please rebuild the index." startup error, and the known limitation shared with earlier versions in the remaining cases. - All rc.7 TODO comments are resolved. `configure.ac` is already 24.0.0 with `CLIENT_VERSION_IS_RELEASE` false, so the version string comes from the `v24.0.0-rc.7` tag. The man pages carry dashpay#8033's `-reindex-chainstate` change; no other pick changes non-debug help text (dashpay#8018's `-testactivationheight` change is debug-only). ## How Has This Been Tested? On this head (2bf133c): - Every develop pick compared with its develop merge (`git patch-id --stable` and the set of changed lines). dashpay#8019, dashpay#8037, dashpay#8032, dashpay#8035, dashpay#8027, dashpay#8034, dashpay#8021, dashpay#8024, dashpay#8026, dashpay#8036 and dashpay#8045: identical. dashpay#8029: the same changed lines; only context differs in `feature_config_args.py`. dashpay#8020: the same changed lines, in `doc/release-notes.md` instead of `doc/release-notes-7437.md`. dashpay#8018: identical except the adaptation above, checked file by file against 900f085 and reviewed separately for consensus equivalence on mainnet, testnet, devnet and regtest. dashpay#8014 and its prerequisites: as in the earlier rounds (adaptations above). - dashpay#8042 port: `v24.0.x`'s divergence from develop, before dashpay#8042 (058b060) versus after it (9e5e3d5), is unchanged in `src/index/*`, `src/validation.{h,cpp}`, the index unit tests and `feature_coinstatsindex.py`, apart from the adaptations listed above. The dashpay#8031, test and man page commits have the same patch-id and message as on dashpay#8033. - Built with `--enable-debug --enable-werror` and Qt: no warnings. - Unit suites pass: `baseindex_tests`, `index_migration_tests`, `txindex_tests`, `blockfilter_index_tests`, `coinstatsindex_tests`, `validation_flush_tests`, `wallet_tests`, `interfaces_tests`, `evo_netinfo_tests` and `evo_snapshot_tests`. With the develop picks (7275005), every `evo_*` suite and `test_dash-qt` (15 classes, 152 passed, 0 failed) passed too. - Functional tests pass: `rpc_netinfo.py`, `feature_masternode_shares.py`, `wallet_migration.py`, `feature_coinstatsindex.py` (including the unclean restart after a reorg), `feature_addressindex.py`, `feature_config_args.py` and `feature_index_prune.py`. On the same C++ tree, these pass as well: `feature_spentindex.py`, `feature_timestampindex.py`, `feature_pruning.py`, `feature_txindex.py`, `feature_reindex.py`, `feature_init.py`, `feature_abortnode.py` and `wallet_reorgsrestore.py`. - Regtest upgrade gates, run on a build of this exact head: all pass. They cover v23.1.10 index migration, index contents vs v23 and `-reindex`, a kill mid-migration, 9 wallets, a pre-activation downgrade and round trip, and v22.1.3/v23.0.2 upgrades. The crash-after-reorg probe and the deleted-index probe are both required to be not reproduced: 0/10 stale (rc.6: about 4/10), and the plain-delete rebuild matches. - Man pages: `help2man` output of the built `dashd`, `dash-cli`, `dash-tx`, `dash-wallet` and `dash-util` matched `doc/man` on the develop picks (apart from the debug-build-only `lock` log category). No later commit changes non-debug help text, so nothing is regenerated beyond dashpay#8033's `-reindex-chainstate` change. - `git merge-tree` against dashpay#8016 (cdb250c) and dashpay#8022 (62609bf), heads fetched 05:23 UTC: clean in both orders, and all three merge to the same tree in every order. From the earlier rounds: the wallet suites and functional tests listed for dashpay#8014, bitcoin#28038 and bitcoin#28542 passed, and the `createwallet` example was checked against the official v24.0.0-rc.6 binary. ## Breaking Changes - From dashpay#8014: migration backups are now named `<name>_<time>.legacy.bak`, the unnamed wallet's watch-only and solvables wallets are named `default_wallet_watchonly` and `default_wallet_solvables`, and `restorewallet` accepts an existing empty directory. - From dashpay#8018: on mainnet, a version 3 ProRegTx or ProUpServTx must list an IPv4 address on the standard port as the first entry of each address list; testnet and devnets are unaffected. - From dashpay#8029: `dashd` no longer creates an empty `dash.conf`. - From dashpay#8031: older versions refuse an index migrated by v24.0.0 until they run `-reindex`; nodes that ran a release candidate should rebuild these indexes once. - From dashpay#8042: an index whose last synced block was lost in an unclean shutdown makes startup fail with a rebuild instruction. The release notes describe these. ## Checklist: - [x] I have performed a self-review of my own code - [x] I have made corresponding changes to the documentation - [x] I have assigned this pull request to a milestone 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

d6c066f chore: add v23.1.10 to the flatpak release history (pasta) 202632c chore: release v24.0.0 (pasta) Pull request description: ## Issue being fixed or feature implemented `v24.0.x` is at `v24.0.0-rc.7` (`111a2c533e`) and still builds as a pre-release: `CLIENT_VERSION_IS_RELEASE` is `false`, so the binaries show the "This is a pre-release test build" warning. The final tag needs that flag set, and the v24.0.0 release notes don't yet list v23.1.10 (released Nov 2), which shipped after the notes were written. ## What was done? - `configure.ac`: set `_CLIENT_VERSION_IS_RELEASE` to `true`. The version is already 24.0.0. - `doc/release-notes/dash/release-notes-23.1.10.md`: archive the v23.1.10 notes, copied byte for byte from the `v23.1.10` tag. - `doc/release-notes.md`: add v23.1.10 to "Older releases" and start the "set of changes" link from `v23.1.10` instead of `v23.1.9`. v23.1.10 is the last release before v24.0.0 and is an ancestor of this branch. - `contrib/flatpak/org.dash.dash-core.metainfo.xml`: add the `23.1.10` entry, copied from the `v23.1.10` tag (`2026-10-30`, the date that tag recorded). The `24.0.0` entry dated `2026-11-05` was already there. Nothing else changes. Code, consensus and activation parameters, chainparams, seeds, translations and man pages are as they were at rc.7. Those were updated earlier in dashpay#7974, dashpay#7982 and dashpay#7989. ## How Has This Been Tested? - `git diff v24.0.0-rc.7` touches only the four files above. In `configure.ac` the only change is the `_CLIENT_VERSION_IS_RELEASE` line. - The archived notes match `git show v23.1.10:doc/release-notes.md` exactly (`cmp`). - CI runs on the PR head and is linked from this PR. - `xmllint --noout` passes on the metainfo file. - Local build of `202632c83c` on macOS with Homebrew Autoconf 2.73 (the later metainfo commit doesn't affect the build). This passed only with a local workaround, so it isn't a clean build pass: - `./autogen.sh && ./configure` succeeds, and the generated `src/config/bitcoin-config.h` has `#define CLIENT_VERSION_IS_RELEASE true`. - The first `make -C src dash-cli` failed with `bitcoin-cli.cpp:151:32: error: use of undeclared identifier 'PACKAGE_NAME'`. This Autoconf leaves all six `PACKAGE_*` macros as `#undef` in the generated header, although configure sets them in `confdefs.h`. - Apart from the release flag, the build inputs are the same as rc.7, so this is a local toolchain issue. Guix builds use their own autotools. - After copying the six `PACKAGE_*` defines from configure's `confdefs.h` into the generated, untracked header, `dash-cli` and `warnings.cpp` compiled. No tracked file was changed. - `dash-cli -version` prints `Dash Core RPC client version v24.0.0`. The compiled `warnings.o` no longer contains the "pre-release test build" string. ## Breaking Changes None. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have commented my code, particularly in hard-to-understand areas - [ ] I have added or updated relevant unit/integration/functional/e2e tests - [x] I have made corresponding changes to the documentation - [x] I have assigned this pull request to a milestone 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

Brings the v24.0.0 release into develop. upstream/master is at the signed v24.0.0 tag (938fba5), so this merges master itself. v24.0.x was cut from develop, and every code change on it is already on develop: its backports are cherry-picks of develop commits, and its remaining commits reached develop through dashpay#7966, dashpay#7973 and dashpay#8042. The textual merge conflicts in dozens of files because v24.0.x carries adapted copies of those changes. All of them resolve to develop's side, which keeps develop's code, translations and configure.ac (24.1.0). Taken from v24.0.0: - doc/release-notes.md: the v24.0.0 release notes; the v23.1.10 notes are archived in doc/release-notes/dash/ - the man pages regenerated for v24.0.0, replacing develop's older v24.0.0 pages; a few entries (-prune, -par, -parbls, -maxconnections) still trail develop's help text, as before, until they are regenerated for the next release - feature_addressindex.py: the test that blocks orphaned while the address index is disabled are removed from it once it is re-enabled Release notes folded into the v24.0.0 notes are removed, including release-notes-8018.md, release-notes-8029.md and release-notes-27114.md, whose changes shipped in v24.0.0 without their files. Develop's release-notes-28113.md and release-notes-28414.md also described descriptorprocesspsbt, which only develop has, so they are trimmed to that RPC instead of removed. Notes for changes v24.0.0 does not include (dashpay#7812, dashpay#7847, dashpay#7860, dashpay#7862, dashpay#8010's bitcoin#26485, bitcoin#25943, bitcoin#27501) stay.

assertions, assert that `getaddressutxos` for `orphan_address` returns an empty
list.

- Around line 1012-1013: Update the descriptor example in the release notes to
show valid JSON as an array containing a descriptor object with both desc and
timestamp fields, matching the input format required by importdescriptors;
retain the surrounding explanation of listdescriptors output.

Review comments at @doc/release-notes/dash/release-notes-23.1.10.md:
- Around line 39-40: Update the release-note statement about trigger NO votes to
clarify that masternodes may vote NO on other active triggers once the window
opens, but do not replace an existing funding vote with NO.

Final validation — Phase 1 + Phase 2

Verified head 800cba1: the merge preserves develop's production sources and version configuration, imports the published release artifacts, and adds an address-index regression scenario consistent with the retained implementation. No actionable defects were confirmed. Static validation included git diff --check; current CI shows successful builds, lint, cppcheck, formatting, and SQLite tests, with other test jobs and multiprocess lint still pending and no failed checks.

Review provenance

Source: reviewer 1: glm-5.3-flash (agent: phase1-reviewer, role: general); reviewer 2: gpt-6.1-sol (agent: phase2-reviewer, role: general); reviewer 3: gpt-6.1-sol (agent: phase2-reviewer, role: dash-core-commit-history); final verifier: gpt-6.1-sol (agent: sol-verifier, role: final-verifier)

Triage: low by gpt-6.1-sol (effort low) — The diff is contained to release documentation, regenerated man pages, and one small functional test addition, with no production-code or critical-surface changes.
Phase 1 reviewers: glm-5.3-flash — general (completed, effort high); agent phase1-reviewer
Phase 1 model: glm-5.3-flash — zai quota: 5h 99% left, weekly 45% left; passed over gemini-3.8-flash-high (antigravity quota lookup failed)
Fresh verifier: gpt-6.1-sol — final-verifier; agent sol-verifier
Phase 2 reviewers: gpt-6.1-sol — general (completed, effort medium); agent phase2-reviewer, gpt-6.1-sol — dash-core-commit-history (completed, effort medium); agent phase2-reviewer
