chore: bump rust-dashcore to the merged sync fixes, minus the sweep-event chain - #4459
chore: bump rust-dashcore to the merged sync fixes, minus the sweep-event chain#4459romchornyi wants to merge 4 commits into
Conversation
…vent chain Six merged dash-spv fixes for stalled and slow sync have been sitting in `dev` unreachable from the app, because the pin does not follow `dev` — it is moved onto side branches cut for one fix at a time. The last bump to a `dev` revision was #4394 on 08-13; #4455 on 08-22 moved it to `a062ccb9`, a cherry-pick of the mnemonic fix on top of an older base. What that leaves out, and what this brings in: | | | |---|---| | #964 | extend the CFHeaders queue from the tick — the queue was never re-extended when block-header storage advanced without an event, and filter sync stopped for good while headers and ChainLocks carried on | | #960 | promote finished header segments from the tick, not only on a message | | #955 | resume on the invariant `start_download` asserts | | #947 | recover masternode sync from a rejected QRInfo | | #946 | release clean storage segments below the committed height during long scans | | #866 | rescan committed filter ranges for newly derived scripts | Plus #945, #928, #963, #965, #967, #970, and #980 — the multilingual BIP-39 fix the current pin carries, so nothing regresses there. **Why a curated branch rather than `dev` HEAD.** `dev` also contains #961, which adds `WalletEvent::TransactionsSwept`, and #962/#966/#969 on top of it. That variant makes four `match` sites in `rs-platform-wallet` non-exhaustive, so pinning `dev` does not compile here — handling it is the substance of #4406 and is not something this bump should duplicate. The branch is `dev` with that chain left out: base `55afccfc` (#945) plus nine cherry-picks, every one applying without conflict. The exclusion has a cost worth stating: #961 stops a never-broadcast transaction from crediting money that does not exist, so a wallet can still read a balance that is too high in that case, and #966/#969 remove quadratic work from the sweep walk. Those arrive with #4406. This trades that for six stall fixes that are blocking users today. Ref: dashpay/rust-dashcore branch `chore/sync-fixes-without-swept`.

Preliminary review — Codex only
At exact head 9924c10, the dependency pin correctly updates all eight rust-dashcore crates, but it also introduces #866's unbounded whole-history match accumulation. Because the accepted compact-filter chain is peer-controlled and the resulting matches are queued together, an eclipsing peer can turn a full-history wallet rescan into a chain-length memory allocation followed by millions of block requests; this must be bounded before the revision is shipped.

- [BLOCKING] Cargo.toml:58: Historical filter rescan permits peer-driven memory and bandwidth exhaustion
The newly pinned revision includes rust-dashcore commit 2dc97c57 (#866), which was absent from the previous pin. Its `rescan_committed_range` loads history in 5,000-filter chunks but inserts every match from the wallet birth height through `batch_start - 1` into one `BTreeMap`; it does not drain matches until the entire range has been scanned. `queue_new_script_matches` then duplicates that chain-length state into the tracker and a `BlocksNeeded` event, and `BlocksManager` queues every missing block for download. This is reachable for Platform recovery wallets because `birth_height_override = Some(0)` explicitly enables scans from genesis. The filter-header manager accepts peer-provided CFHeaders, computes their self-consistent chain, and stores it without an independently authenticated checkpoint, while filters are only checked against that same peer-provided chain. An eclipsing compact-filter peer can therefore construct historical filters that avoid the current watch set but match a receive script that a later valid payment causes gap-limit maintenance to derive. At the current multi-million-block chain length, the backward sweep can exhaust mobile memory before emitting its event; if it survives, it schedules millions of full-block reads or downloads. Preserve the historical rescan cursor and process a bounded number of matches per iteration, with an explicit cap or recovery policy for implausibly high match rates, or repin without #866 until that upstream fix is available.

Decision on the #866 blocker: let's re-pin without #866 for this release. Two reasons, one of them from your own data:
Dropping #866 keeps the six sync-stall fixes — the point of this PR — with no new behavior classes. #846's mid-sync invisibility stays status-quo (not a regression), and the explicit migrated-wallet heal (#4377, merged) does a full rescan so it doesn't depend on the #866 sweep. Concretely:
Getting #974 reviewed upstream is now a priority on our side. |
…ashcore-sync-fixes # Conflicts: # Cargo.lock
Per the decision on the blocker: the pinned branch is re-cut without #866's `rescan_committed_range`. Two reasons, and the second is the one that decides it. The Codex finding stands — the sweep accumulates every match from the birth height into one `BTreeMap` and queues them together, so an eclipsing compact-filter peer can turn a full-history rescan into a chain-length allocation followed by millions of block requests, and nothing upstream bounds it yet. More decisive is the honest case. On a real long-history CoinJoined restore the #846 backward sweep ran 191 times, reached a 2.9 GB footprint, and was killed by jetsam before finishing; the coalescing fix for that is dashpay/rust-dashcore#974, which is not merged. Shipping #866 without #974 would trade a mid-sync stall for a restore that kills the app — and long-history migrated wallets are exactly this release's audience. What the pin still carries is the point of this PR: #964, #960, #955, #947 and #946, the six sync-stall fixes, plus #945, #928, #963, #965, #967, #970 and #980. Dropping #866 restores the status quo of the previous pin rather than introducing a regression — #846's mid-sync invisibility was never fixed in what shipped — and the migrated-wallet heal (#4377) does a full rescan, so it does not lean on this sweep. #866 and #974 come back together next cycle, with a bounded drain for the accumulation finding. Branch: dashpay/rust-dashcore@chore/sync-fixes-without-swept, re-cut at 33030acf (base #945 plus eight cherry-picks, #866 omitted).

Final validation — Codex/Sol only (Phase 2 disabled)
The exact-head repin successfully removes #866's historical committed-range rescan, resolving the prior blocking memory and bandwidth exhaustion finding. One nonblocking regression remains: the curated revision replaces the base pin's August 19 mainnet seed snapshot with an older, smaller, internally inconsistent August 17 snapshot despite claiming equivalent coverage for #970.

The base revision `a97b32c6` bundles the August 19 mainnet snapshot at height 2,524,354 with 2,105 entries, but `33030acf` bundles the August 17 snapshot at height 2,523,213 with only 2,102 actual entries.

Auto-resolved by the review system based on the latest commit diff. If you believe this was closed in error, reopen the thread.
The repin was rolling the bootstrap pool back. `a97b32c6` — the revision `v4.2-dev` pins today — carries the 2026-08-19 probe at tip height 2,524,354; the curated branch stopped at the 2026-08-17 one at 2,523,213, losing three endpoints including the evonodes 5.199.166.45 and 65.109.84.202 that the newer probe recorded as reachable with valid Platform TLS. `dash-network-seeds` embeds this file with `include_str!`, so that is a live regression in the shipped seed list, not a metadata detail. My check for "the current pin loses nothing" compared commit subjects, and both refreshes are titled `chore(seeds): refresh mainnet seed list`, so #970 looked like the same change. It is not: #970 is a 36/34-line refresh that went into `dev`, while `a97b32c6` is a separate 204/153-line probe that only ever existed on the side branch. Matching on subject was too weak a test for a generated data file. The branch now cherry-picks `a97b32c6` after the sync fixes, so `mainnet.txt` is byte-identical to what the current pin ships. Re-verified: 560 dash-spv tests, 13 dash-network-seeds tests, and `cargo check --workspace` clean at the new revision. Branch: dashpay/rust-dashcore@chore/sync-fixes-without-swept at 3d13d983.

The exact-head pin consistently updates the rust-dashcore dependencies, excludes #866, and restores the base revision's mainnet seed snapshot byte-for-byte. One nonblocking lifecycle defect remains: masternode work preserved during a total peer outage is not resumed after reconnection and is ultimately discarded before a fresh QRInfo pipeline starts.

- [SUGGESTION] Cargo.toml:58: Resume the masternode work preserved across a total disconnect
The pinned `dash-spv` revision changes `MasternodesManager::on_disconnect` to requeue in-flight MnListDiff requests while retaining the QRInfo slot and `pipeline_mode`, but the total-disconnect lifecycle cannot consume that preserved state. `SyncManager::stop_sync` first moves the manager to `WaitingForConnections`; on reconnection, the default `start_sync` only changes it to `WaitForEvents`, while the masternode `tick` returns immediately unless the state is `Syncing` or `Synced`. When the restarted header manager later emits `BlockHeaderSyncComplete`, the `WaitForEvents` restart branch calls `clear_pending()` before sending a fresh QRInfo, discarding the requeued diffs and any QRInfo result retained in `pipeline_mode`. Thus an all-peer outage during masternode synchronization still restarts the full QRInfo pipeline instead of resuming the work this change explicitly preserves. Add a masternode-specific reconnect/start path that reissues the retained MnListDiff work and outstanding QRInfo, and cover the full `PeersUpdated(0)` to reconnection lifecycle with a progress test.

Six merged
dash-spvfixes for stalled and slow sync are unreachable from the app. The pin does not followdev— it is moved onto side branches cut for one fix at a time. The last bump to adevrevision was #4394 on 08-13; #4455 on 08-22 moved it toa062ccb9, a cherry-pick of the mnemonic fix on top of an older base, so everything merged intodevsince 08-13 is still not shipping.Reported symptom this addresses: sync freezes partway — one user is stuck at 71.3% on a build carrying the current pin — while headers and ChainLocks keep arriving, so the client looks alive.
What this brings in:
start_downloadassertsPlus #945, #928, #963, #965, #967, #970 and #980 — the multilingual BIP-39 fix the current pin already carries, so nothing regresses there.
What was done?
Cargo.tomlrepins all eight rust-dashcore crates,Cargo.lockregenerated. No other file changes.Why a curated branch rather than
devHEAD.devalso contains #961, which introducesWalletEvent::TransactionsSwept, plus #962/#966/#969 on top of it. That variant makes fourmatchsites inrs-platform-walletnon-exhaustive —changeset/core_bridge.rs:607,wallet/core/balance_handler.rs:44,wallet/identity/network/payment_handler.rs:249and:270— so pinningdevdoes not compile here. Handling that event is the substance of #4406 and this bump should not duplicate it.The pinned branch is
devwith that chain left out: base55afccfc(#945) plus nine cherry-picks, every one applying without conflict. Branch:dashpay/rust-dashcore@chore/sync-fixes-without-swept.The exclusion has a cost, stated plainly.#961 stops a never-broadcast transaction from crediting money that does not exist, so a wallet can still read a balance that is too high in that case; #966 and #969 remove quadratic work from the sweep walk. Those arrive with #4406. This trades them for six stall fixes that are blocking users now, and #4406 supersedes this pin when it lands.
How Has This Been Tested?
cargo check --workspaceagainst the new pin — clean. This was the point of the exclusion, and it was verified by first tryingdevHEAD and watching it fail on the four non-exhaustive matches above.cargo test -p dash-spv --libon the pinned branch — 563 passed, 0 failed, 2 ignored.a062ccb9= chore: v0.24-dev backports part 2 #980,a97b32c6= fix(dashmate): empty masternode status while syncing #970) have equivalents in the pinned branch.Not yet exercised end-to-end against the reported 71.3% freeze — that needs the reporter's
dash_spvlog or a rebuild on their device. #964 is the closest match to the symptom, but #947, #960 and #946 are also plausible from the description alone, and I would not claim which without the log.Breaking Changes
None. Dependency revision only.
