bitcoin#25193 (#7883) brought back bitcoin#33208: after an unclean shutdown an index can name a block that was never flushed, and the node refuses to start until the index is rebuilt. Alternative to #8030: the upstream fixesbitcoin#33212 and bitcoin#34897 applied 1:1, with the upstream prerequisites they need instead of Dash-only adaptations.
Two Dash-only commits: Dash's address, spent, timestamp and governance collateral indexes erase entries on rewind, so the committed locator is moved below them, and each rewound block's erasures are written in one batch with that locator so an interrupted rewind can't leave it above erased entries.
Omitted hunks and Dash adaptations are listed in each commit's BACKPORT NOTE. bitcoin#29867 is skipped: Dash never took the bitcoin#28955 lock release it fixes.

BaseIndex now limits commits to the chainstate’s last flushed block and tracks uncommitted tips for eager-writing indexes. Rewinds use per-block batches that include locator updates. Chainstate records the block associated with flushed coins. Wallet paths update and persist best-block locators during processing, rescans, removal, and backup. Wallet loader shutdown uses UnloadWallets. New tests cover index commits, rewinds, recovery, reorganizations, pruning, process termination, and wallet rescans.

Merge Risk: Moderate · up to 73ba9
Resolve the pruning/restart recovery issue before merging: an unclean stop can require rebuilding an index rather than simply resynchronizing it. Smaller wallet shutdown, persistence-error, and test failure-path issues also remain. Existing-wallet locator preservation and the test call signature are corrected.

Make the rewind locator write atomic with the spent-index erase, or repair the index on restart.
SpentIndex::CustomRewind erases spent entries in separate batches and writes the new locator last. A crash between these steps leaves the old locator on disk. If the restarted chain tip is the old tip, BaseIndex::Init marks the index synced. The erased spends are then never re-indexed, and getrawtransaction omits spentTxId for those outputs.

Keep the prune lock at the durable index locator height.
SetBestBlockIndex sets the prune lock to the in-memory index height. Commit now skips the write when the index tip is not an ancestor of the last flushed block, so the durable locator can fall behind. Pruning can then unlink blocks above that locator before the index commit. A crash in that window makes the next startup fail with the prune-violation error, or with a fatal block-read error during index sync. The null-block change at line 489 does not cause this. The non-null prune lock and the new commit guard do.

Keep the saved best-block locator when loading a wallet.
LoadWallet() calls SetLastBlockProcessed(), which now writes the chain tip locator to the wallet database. AttachChain() then reads that locator for the cross-chain genesis check and the rescan start height. The saved locator is lost. A wallet from another chain can attach, and blocks after the saved locator can be skipped. Use the in-memory setter in LoadWallet(). AttachChain() already sets the in-memory tip.

Check last_scanned_height before dereferencing it.
When shutdown is already requested, a genesis rescan skips the loop. ScanResult::status remains SUCCESS, while last_scanned_height remains unset. The startup path then dereferences the empty optional. Add an optional-value check before SetLastBlockProcessed.

Pull request description:
Implements the idea discussed in bitcoin#29652 (comment)
Currently, `m_last_block_processed` and `m_last_block_processed_height` are not guaranteed to match the block locator stored in the wallet, nor do either of those fields actually represent the last block that the wallet is synced up to. This is confusing and unintuitive.
This PR changes those last block fields to be updated whenever the wallet makes a change to the db for new transaction state found in new blocks. Whenever a block is received that contains a transaction relevant to the wallet, the last block locator will now be written to disk. Furthermore, every block disconnection will now write an updated locator.
To ensure that the locator is relatively recent and loading rescans are fairly quick in the event of unplanned shutdown, it is also now written every 144 blocks (~1 day). Additionally it is now written when the wallet is unloaded so that it is accurate when the wallet is loaded again.
Lastly, the `chainstateFlushed` notification in the wallet is changed to be a no-op. The best block locator record is no longer written when `chainstateFlushed` is received from the node since it should already be mostly up to date.

…n tip in NextSyncBlock()
db3c25c index: add explicit early exit in NextSyncBlock() when the input is the chain tip (Hao Xu)
Pull request description:
When `pindex_prev` is the chain tip, `NextSyncBlock()` should return `nullptr` (there's no next block to sync). Currently this works, but relies on the fork/reorg path to produce the result: `chain.Next(tip)` returns `nullptr`, falling through to `FindFork(tip)` which returns `tip` itself, then `chain.Next(tip)` returns `nullptr` again.
Add an explicit early return for this case. This makes `NextSyncBlock()`'s three cases self-documenting:
1. next block exists on the active chain — return it
2. at the chain tip — return `nullptr`
3. on a stale branch — find the fork point and return the block after it
It also makes the existing comment ("Since block is not in the chain") accurate — the tip is in the chain, so it shouldn't reach that path.

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.

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).

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: the feature_pruning.py restart keeps -txindex=0 and DEPLOYMENT_ARGS as the other node 0
starts in that test do, since -txindex is on by default in Dash and is incompatible with pruning.
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.

Final validation — Phase 1 + Phase 2
Verified the findings against exact head 8bad97b and confirmed one blocking crash-recovery defect shared by the address, spent and timestamp indexes. The three prerequisite findings concern upstream test areas explicitly excluded in the author's backport notes; no local builds or tests were run. Current CI passes lint, cppcheck and ClangFormat, while the sanitizer job fails on an unsigned-to-signed conversion in unchanged src/qt/walletview.cpp:205, which appears unrelated; the main CI workflow remains in progress.
Triage: normal by gpt-6.1-sol (effort low) — The diff intricately changes index persistence, rewind handling, and wallet synchronization bookkeeping, but does not change consensus rules, funds movement or coin selection, cryptography, key handling, network deserialization, or storage migrations.

- [BLOCKING] src/index/timestampindex.cpp:88-90: Persist the rewind locator atomically with destructive updates
The new locator adjustment is written only after the rewind's erasures have already been persisted independently. With both chainstate and the index committed at A100, disconnecting A100 erases its timestamp entry at line 81. A process crash before this final locator batch leaves the database naming A100 without its entry. If the unflushed disconnection is lost on restart, BaseIndex::Init() sees the saved locator equal to the active tip, treats the index as synced, and never recreates that entry. AddressIndex::CustomRewind has the same ordering through RewindBatch(), and SpentIndex::CustomRewind through EraseSpentIndex(). This leaves the Dash-specific rewind recovery repair incomplete: completing the locator write fixes completed rewinds, but not interruption during one. Put the destructive updates and their corresponding locator adjustment in the same atomic database batch, either for the complete rewind or for each block with a matching intermediate locator.

Resolved (re-reviewed at 5e373774): Your 0afd6c3 change writes the timestamp erasures and lowered locator in the same batch, closing the interruption window. I also verified that address and spent rewinds pair each block's updates with its locator through RewindBlockByBlock, while governance collateral retains its single atomic batch.
…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.

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.

Remove orphaned eager-index entries when the uncommitted tip is dropped.
When Init() drops an uncommitted tip that is missing from the block index, it resumes from the locator and keeps the entries that eager indexes already wrote for blocks above it. Later sync only appends blocks on the new chain, so getaddressdeltas, getspentinfo, and getblockhashes can return entries for blocks no longer on the active chain. A safe localized fix is not established by the inspected code, so no edit is proposed.

Record the index tip for eager appends made outside Commit().
For eager indexes, BlockConnected() and the sync loop append entries without recording a tip. Only a skipped Commit() writes the uncommitted tip. After an unclean shutdown in that gap, Init() resumes from the older locator. Entries for an abandoned block above it are never rewound, and the RPC readers still return them.

Entries for a dropped uncommitted tip can remain after a pre-PR run.
When the uncommitted tip is not a descendant of the locator, BaseIndex::Init() clears the tip and resumes from the locator. Entries already written for the tip's branch stay in the index. If that branch is inactive, sync from an active-chain locator does not rewind them. The address index then keeps entries for blocks outside the active chain, and the address RPC can return them once the index reports synced.
This state needs a specific sequence. A post-PR binary leaves an uncommitted tip. A pre-PR binary then runs on the same datadir and commits a locator that does not cover that tip. The tip's branch must also become inactive, which requires a reorg away from that branch during the mixed-version run. If the tip stays on the active chain, dropping it leaves no stale entries.
The Init() path needs to remove or rewind the entries of the dropped branch before it resumes from the locator. Removing only the tip does not remove those entries.

- [BLOCKING] src/index/base.cpp:124-129: Do not discard an unknown tip without recovering its eager updates
A missing uncommitted tip can result from an ordinary unclean shutdown, not just obsolete metadata. Start with a committed locator at block 100, let ThreadSync append blocks 101–103 before the block-index database is written, and let its final skipped Commit persist U=103. The address index's history additions and unspent-output additions/deletions are already written independently. After a crash, the block index can end at 100; this path deletes U, resumes at 100 and immediately reports the index synced, without undoing the changes for 101–103. getaddressutxos and getaddressbalance read those stored entries without active-chain filtering, so they can expose nonexistent outputs or omit outputs spent only by the lost blocks. A competing branch does not remove the stale entries because the index no longer knows which branch to rewind. Before this PR's commit guard, the end-of-sync locator named the lost block and startup rejected the index instead of silently using it. Preserve sufficient rollback information independent of the block index, or reject the unrecoverable index with a rebuild instruction rather than clearing its marker and advertising it as synced. Extend the unknown-tip regression to include actual persisted entry changes; it currently inserts only a marker.

- [BLOCKING] src/index/govcollateralindex.cpp:129-133: Use the recovered tip in the governance startup precheck
CanSync checks block availability from DB_BEST_BLOCK alone, but BaseIndex::Init now resumes from a validated DB_UNCOMMITTED_TIP. During initial index sync, the committed locator can remain old or empty while U reaches the chain tip. SetBestBlockIndex advances this index's prune lock to that tip, so a subsequent pruning flush can remove blocks between the old locator and U. If the process crashes after that flush but before the queued ChainStateFlushed callback commits the locator, U and its block-index entry survive, and BaseIndex could resume from U without reading the pruned interval. This precheck nevertheless scans back toward the old locator, returns false on the pruned blocks, and causes init.cpp to omit the collateral index and disable governance with a reindex warning. Share the validated effective resume-point selection with BaseIndex::Init so this Dash-specific precheck tests the blocks startup will actually need. Before the commit guard, the end-of-sync commit advanced the locator itself, so this recoverable-marker mismatch did not occur.

These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
Declared partial: omitted wallet-tool unclean-shutdown test — INTENTIONAL_EXCLUSION: Upstream commit 0b75315 adds both the expected_ret_code helper transformation and tool_wallet.py::test_dump_unclean_lsns, including its invocation and BDB read-only-parser rejection check. Dash carries the helper transformation but neither the scenario nor its invocation; git log -S on the merge-base history confirms that scenario was not previously imported. Commit ee9bb26 explicitly selects only the test_node.py hunk and excludes the independent bitcoin#26606 parser and its test. Commit 059ce4a likewise explicitly selects only kill_process() and excludes the tool_wallet.py caller. The PR description advertises bitcoin#26606 as one hunk and incorporates these notes, so adding the parser-dependent test is outside the selected backport.

Resolved (re-reviewed at 73ba99d2): Your CanSync() change now uses the same ResumeBlock() selection as initialization and checks availability above its active-chain fork, while preserving the missing-locator restriction. Your regression test covers both pruned data below the recovered point and missing data above it.
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.

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.

Avoid writing the index's private locator key from this test.
The test writes key 'B' and a fake CBlockLocator through a separate CDBWrapper at indexes/govcollateralindex. 'B' is the private DB_BEST_BLOCK constant in src/index/base.cpp, so the test depends on storage internals. Extract the sync decision into a testable helper that takes the locator and uncommitted tip, or cover the missing-block restart in a functional test.
As per coding guidelines, unit tests check a class "through the standard fixtures and its public surface, (not friend or injected private state); if the behavior can't be observed that way, extract a testable function or write a functional test."

Check abandoned-branch block data in CanSync and BaseIndex::Init.
When the uncommitted tip is off the active chain, CanSync checks block data only on the active chain, from the tip down to the fork. CustomRewind then reads the abandoned blocks from that tip down to the fork. If pruning removed those blocks, the index fails during its sync thread with FatalError. That happens after CanSync returned true and governance stayed enabled. Require BLOCK_HAVE_DATA on the abandoned segment as well, or fail the precheck when it is missing. BaseIndex::Init has the same gap in its prune check.

Add a test for a stop after real appends and before the uncommitted-tip write.
The lost-block case creates its entry and marker with WriteEntry() and SetUncommittedTip(). It does not use CustomAppend() or Commit(). The sync-based test checks the marker only after sync completes. No inspected test stops the index after CustomAppend() writes entries and before the next Commit() writes the uncommitted tip. Add a case for that window. It should leave real appended entries without a marker, restart the index, and check that startup resumes from the committed locator and recovers from those entries.

Minor comments:
Review comments at @src/index/govcollateralindex.cpp:
- Around line 139-143: Update CanSync to verify BLOCK_HAVE_DATA for the
abandoned segment from the uncommitted tip back to the fork before allowing
sync, and update the corresponding prune check in BaseIndex::Init to cover that
segment as well. Preserve the existing active-chain checks and fail the precheck
when required block data is missing.
Review comments at @src/test/governance_collateral_tests.cpp:
- Around line 238-241: Remove the test’s direct write of the private `'B'`
locator key through a separate `CDBWrapper`. Instead, test the sync decision
through a helper that accepts the locator and uncommitted tip, or verify the
missing-block restart in a functional test, without depending on private index
storage.

Re-review — Final validation — Phase 1 + Phase 2
At exact head 73ba99d, all three prior blockers are fixed; static verification found two non-blocking regression-coverage gaps and an optional commit-history cleanup. Live CI now also reports linux64-test failing in wallet_fundrawtransaction.py --legacy-wallet --nohd, which exercises the changed wallet subsystem and remains potentially related; the ASan failure is the unchanged qt/walletview.cpp signedness issue independently fixed by develop commit 146ba3b. Multiprocess build and TSan tests remain pending; no local builds or tests were run, and the supplied base drift has no overlapping changed files or merge conflicts.

💬 Nitpick: Fold the recovered-tip corrections into their introducing commit <commit:3cc304eda2>:1
If the series will be merged without squashing, fold 3cc304e and 73ba99d into 5e37377, including their regression tests, and update its message. Both follow-ups correct the startup contract introduced by that commit: governance must use the recovered resume point, and an unknown recorded tip must cause startup rejection. In particular, 5e37377's message explicitly promises the fallback that 73ba99d removes. Folding these corrections preserves the useful upstream backport boundaries while leaving one coherent commit for the new Dash recovery mechanism.
Triage: normal by gpt-6.1-sol (effort low) — The changes intricately alter index flush, rewind, and crash-recovery behavior alongside wallet notifications, but do not change storage migrations or another specified critical surface.
These findings are from an automated code review. Verify each finding against the current code and only fix it if needed.
In `src/wallet/wallet.cpp`:
- [SUGGESTION] src/wallet/wallet.cpp:3775-3778: Restore the declared-omitted wallet crash/reorg test coverage
The production locator changes are present, but their upstream crash-recovery regression coverage is not. bitcoin#30221 changes wallet_reorgsrestore.py to verify that the coinbase is no longer abandoned after an unclean restart; bitcoin#32580 additionally verifies the one-block startup rescan and restored immature balance. Dash's existing wallet_reorgsrestore.py has no corresponding crash scenario, and the adapted scan_for_wallet_transactions unit test does not exercise process termination and startup recovery. The BACKPORT NOTEs explicitly declare this omission, so it is not an undeclared or blocking prerequisite failure. Add equivalent Dash-adapted crash/rescan coverage, including the relevant setup from bitcoin#31757 as necessary, or link a tracking issue before deferring this coverage.
In `src/validation.cpp`:
- [SUGGESTION] src/validation.cpp:3317-3320: Adapt the omitted last-flushed-block assertions from bitcoin#34897
bitcoin#34897 adds two GetLastFlushedBlock() assertions to write_during_multiblock_activation: the initial flush must record second_from_tip->pprev, and the periodic flush during activation must record second_from_tip rather than the eventual chain tip. The BACKPORT NOTE explicitly omits these assertions. Dash's baseindex tests verify commit gating and previously flushed heights, but do not exercise the intermediate flush during multiblock activation, which is the validation-side behavior this change must preserve. Adapt that scenario into an existing validation unit suite, or link a tracking issue before deferring it. This is a non-blocking coverage gap, not evidence that the production adaptation is incorrect or that the entire prerequisite PRs must be imported.

source: gpt-6.1-sol (phase2-reviewer: general, backport-reviewer, dash-core-commit-history)
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.

…ncommitted tip
Since dashpay#8042 the governance collateral index records the tip of a commit
it had to skip and resumes from it after an unclean stop. That tip is
above the last coins flush, so the stop can leave it missing from the
block index, or with only its header:
- missing: Init() fails with "Please rebuild the index", and as the index
can't be disabled, the node doesn't start until -reindex;
- header-only, and the chain then reorgs below it: the rewind fails to
read it, the node stops with a fatal error, and every restart does the
same.
A collateral only confirms while its block is on the active chain
(CGovernanceObject::IsCollateralValid), and appending a block again
overwrites its entries, so entries the index can't rewind are harmless.
Resume from the locator when the block index lost the tip, and let the
rewind keep the collaterals of a block without data. The index still
resumes from a tip the block index has, which on a pruned node keeps the
blocks below it out of the sync check.

Pull request description:
## Issue being fixed or feature implemented
Backports and release prep for v24.0.0-rc.7, on top of `v24.0.x` at 8d195f1 (v24.0.0-rc.6, #8013). This PR collects the develop merges labeled `backport-candidate-24.0.x`, the v24.0.x port of #8042 with the index fixes from #8033, and the release notes for them, so rc.7 has a single backport PR to merge.
## What was done?
### Picked
Cherry-picked with `git cherry-pick -m1 -x`, in develop merge order, except that bitcoin#28038 goes before bitcoin#28542 as in Bitcoin Core. Each pick changes exactly the same lines as its develop merge, except as noted below for bitcoin#28542, #8014, #8020 and #8018.
- #8019 fix(qt): stop reporting refused shared masternode broadcasts as sent
- bitcoin#28038 (from #7863): prerequisite of #8014
- bitcoin#28542 (from #7762): prerequisite of #8014. Its `test_conflict_txs` migrates through `self.migrate_wallet`, as on develop since bitcoin#28868.
- #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
- #8037 docs: list the config file path each Linux init system uses
- #8029 fix: let dashd -version, -help and first start work without an existing data directory
- #8032 fix(qt): don't offer a new operator key when reopening a shared masternode session
- #8035 fix(qt): don't strand coins reserved for a shared masternode session
- #8027 fix(qt): fund a shared masternode's service update from this wallet by default
- #8034 fix(qt): check a shared masternode's service and refund addresses before coins are reserved
- #8021 fix(qt): don't load a newer shared masternode session copy that changes your own share
- #8024 fix(qt): keep the shared masternode dissolve dialog consistent with what it will send
- #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.
- #8026 fix(qt): keep shared masternode contribution fields locked while coins are reserved (merged on develop as cc73a04; GitHub shows the PR as closed)
- #8018 fix(consensus): require IPv4 masternode primaries until IPv4 is optional, pin mainnet ports, with the adaptation below
- #8036 fix(qt): let a shared masternode participant follow a revised invitation that keeps their share
- #8045 test: scale the mempool-loaded wait by timeout_factor so TSAN reindex restarts stop timing out
### Index fixes: #8042 port and #8033
The index commits are #8042 (merge 9e5e3d5), ported commit by commit to `v24.0.x`, plus the parts of #8033 that #8042 doesn't cover. #8042's v24.0.x port replaces #8033's bitcoin#33212, bitcoin#34897 and rewind-locator commits, and #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 #8033, and #8031 comes in through it (adapted to the `v24.0.x` `CCoinsViewDB` constructor), not as a separate pick.
- bitcoin#25193 (from #7883, via #8033): indexes: read the locator's top block during init, allow interaction with `-reindex-chainstate`
- From #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 #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 #8033: #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 #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 #8042 only by differences that already existed before it.
#### Dash adaptations for #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 #8014#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`: #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 #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
- #8016 backport: v23.1.10 fixes for v24.0.x
- #8022 backport: bind CoinJoin signatures to the approved transaction (#7815) for v24.0.x, which depends on #7815 merging on develop
#8016 and #8022 each merge cleanly with this branch in either order, and all three merge to the same tree in any order.
### Not picked
- #8025: closed; superseded by #8014 (picked above)
- #8031 is not picked separately; it comes through #8033's commits above.
- #8039, #8040, #8041, #8043, #8044 (CI and tooling), #7905, follow-ups to #8042, and the PRs in the 24.1 milestone.

### 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 (#7754) and the DKG bad votes for missing transaction relay or compact filters (#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 (#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 (#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. #8018's IPv4-primary and mainnet standard-port rules are under Extended addresses, with a pointer from the masternode upgrade notes; #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 (#8042, #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 #8033's `-reindex-chainstate` change; no other pick changes non-debug help text (#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). #8019, #8037, #8032, #8035, #8027, #8034, #8021, #8024, #8026, #8036 and #8045: identical. #8029: the same changed lines; only context differs in `feature_config_args.py`. #8020: the same changed lines, in `doc/release-notes.md` instead of `doc/release-notes-7437.md`. #8018: identical except the adaptation above, checked file by file against 900f085 and reviewed separately for consensus equivalence on mainnet, testnet, devnet and regtest. #8014 and its prerequisites: as in the earlier rounds (adaptations above).
- #8042 port: `v24.0.x`'s divergence from develop, before #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 #8031, test and man page commits have the same patch-id and message as on #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 #8033's `-reindex-chainstate` change.
- `git merge-tree` against #8016 (cdb250c) and #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 #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 #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 #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 #8029: `dashd` no longer creates an empty `dash.conf`.
- From #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 #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.

Pull request description:
## Issue being fixed or feature implemented
`wallet_fundrawtransaction.py` fails intermittently, and failed `linux64-test` on #8042. In local runs of `--legacy-wallet --nohd` against develop, 7 of 120 failed, at two different `testmempoolaccept` assertions. Both come from the same cause: the wallet sizes fees for 71-byte signatures, an ECDSA signature is occasionally a byte shorter (about 1 in 64), and both checks are funded at exactly a fee boundary.
- `test_22670` (6/120): the node runs with `-minrelaytxfee=0.1`, so the wallet pays 0.1 DASH/kB on its 519-byte estimate. That equals `testmempoolaccept`'s default `maxfeerate`. When one of the three signatures is short, the transaction is 518 bytes and is rejected with `max-fee-exceeded`.
- `test_external_inputs` (1/120): the external input's size is measured from one signing and the transaction is funded at the minimum relay fee. When the measured signature was the short one, the next signing is a byte longer and the transaction is rejected with `min relay fee not met`. This is bitcoin#28437, fixed upstream by bitcoin#28604.
## What was done?
- Backport bitcoin#28604: fund the external-input transactions at 2 duff/B instead of the minimum relay fee, as the fee rate itself doesn't matter there. All six upstream hunks apply as upstream wrote them (`fee_rate=2` as a named parameter, which develop supports since the partial bitcoin#26485 backport).
- `test_22670`: call `testmempoolaccept` with `maxfeerate=0`, so it checks only the minimum relay fee, which is what the test is about. This is Dash-only: upstream measures vsize, which a byte of witness data rarely changes, so it doesn't hit this.
## How Has This Been Tested?
Built develop (9e5e3d5) and ran `wallet_fundrawtransaction.py --legacy-wallet --nohd` repeatedly, with the failing `testmempoolaccept` results logged:
- Without this PR: 7/120 failed (6 `max-fee-exceeded` with a 518-byte transaction, 1 `min relay fee not met`).
- With this PR: 150/150 passed; 5 of those runs produced the 518-byte transaction that used to be rejected, and it was accepted.
- `--legacy-wallet`, `--descriptors` and `--legacy-wallet --nohd` each pass once more with the final file.
## Breaking Changes
None. Test-only.

…ncommitted tip
Since dashpay#8042 the governance collateral index records the tip of a commit
it had to skip and resumes from it after an unclean stop. That tip is
above the last coins flush, so the stop can leave it missing from the
block index, or with only its header:
- missing: Init() fails with "Please rebuild the index", and as the index
can't be disabled, the node doesn't start until -reindex;
- header-only, and the chain then reorgs below it: the rewind fails to
read it, the node stops with a fatal error, and every restart does the
same.
A collateral only confirms while its block is on the active chain
(CGovernanceObject::IsCollateralValid), and appending a block again
overwrites its entries, so entries the index can't rewind are harmless.
Resume from the locator when the block index lost the tip, and let the
rewind keep the collaterals of a block without data. The index still
resumes from a tip the block index has, which on a pruned node keeps the
blocks below it out of the sync check.

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 #7966, #7973 and #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
(#7812, #7847, #7860, #7862, #8010's bitcoin#26485, bitcoin#25943,
bitcoin#27501) stay.

Pull request description:
## 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 #8042, the mainnet V24 schedule by #7973, the cppcheck CI move by #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: #7812, #7847, #7860, #7862, bitcoin#25943, bitcoin#26485 and 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.

Issue being fixed or feature implemented
bitcoin#25193 (#7883) brought back bitcoin#33208: after an unclean shutdown an index can name a block that was never flushed, and the node refuses to start until the index is rebuilt. Alternative to #8030: the upstream fixes bitcoin#33212 and bitcoin#34897 applied 1:1, with the upstream prerequisites they need instead of Dash-only adaptations.
What was done?
ChainStateFlushed, so the indexes: Don't commit ahead of the flushed chainstate bitcoin/bitcoin#34897 notification applies unchanged.kill_process()for the index: Don't commit state in BaseIndex::Rewind bitcoin/bitcoin#33212 functional test.BaseIndexfixes on the same code.Omitted hunks and Dash adaptations are listed in each commit's BACKPORT NOTE. bitcoin#29867 is skipped: Dash never took the bitcoin#28955 lock release it fixes.
How Has This Been Tested?
baseindex_tests: committed height stays at the last flush (indexes: Don't commit ahead of the flushed chainstate bitcoin/bitcoin#34897); erased blocks are indexed again after a restart, including after a rewind interrupted between blocks (Dash-only commits, each fails with its fix removed).blockfilter_index_tests/index_reorg_crash(index: fix wrong assert of current_tip == m_best_block_index bitcoin/bitcoin#32878),wallet_tests/scan_for_wallet_transactions(wallet: Ensure best block matches wallet scan state bitcoin/bitcoin#30221).feature_coinstatsindex.pyunclean restart after a reorg (index: Don't commit state in BaseIndex::Rewind bitcoin/bitcoin#33212),feature_pruning.pynew index on a pruned node (indexes: set prune lock to genesis before first block bitcoin/bitcoin#36150).Breaking Changes
None. An index's committed best block may trail its in-memory tip until the next flush and re-syncs after an unclean shutdown.
