feat(dash-spv): startup consistency check and reorg-in-progress sentinel#167
Merged
Conversation
…o `MetadataStorage` Add four new methods on the `MetadataStorage` trait: `delete_metadata`, `write_reorg_sentinel`, `clear_reorg_sentinel`, and `is_reorg_sentinel_set`. The sentinel is a zero-byte file at `metadata/reorg_in_progress.dat` written via `atomic_write` and removed via `tokio::fs::remove_file`. Implementations are added to `PersistentMetadataStorage` and delegated through `DiskStorageManager`. These primitives back the upcoming startup consistency check: the cascade will write the sentinel before truncation and clear it after, so a crash mid-cascade is detectable on the next startup.
…uccess Thread a `metadata_storage` handle into `ReorgStorages` so `handle_reorg` can mark the cascade in progress immediately before generation bump and clear it once the last `truncate_above` returns. A crash between the write and the clear leaves the sentinel on disk, which the upcoming startup consistency check will use to recompute a safe tip. Add a unit test that drives a successful cascade and confirms the sentinel is set during the cascade and cleared on completion.
…nvariants Add a standalone async function that enforces four invariants between the block-header tip and the downstream storages: - `filter_header_tip <= block_header_tip` - `filter_tip <= filter_header_tip` - `block_storage_tip <= block_header_tip` - BIP157 filter header range readable end-to-end For each violation, the offending storage is truncated to the safe tip and persisted immediately. The repair is idempotent. Wired into `DiskStorageManager::new` so it runs unconditionally on every open, before any sync task observes the storages.
…l is present Add `highest_valid_tip` on `PersistentBlockHeaderStorage`. It walks backward from the current tip, returning the first height whose `prev_blockhash` resolves to the immediately preceding height in `header_hash_index`. Used by `check_and_repair_consistency` when the reorg-in-progress sentinel is found on startup: every storage is truncated to the recovered safe tip and the sentinel is cleared before the regular invariant checks run.
… file is corrupt `SegmentCache::load_or_new` previously errored on the first unreadable segment file, refusing to open the cache. Walk segment ids from highest to lowest instead, logging a warning and skipping any segment whose `Segment::load` fails. The first readable id becomes the tip; the lowest readable id at or below it becomes the start. This keeps the SPV client startable when an isolated segment file is corrupt, and gives the startup consistency check a stable base to truncate downstream storages against. Add a unit test using a non-minimal VarInt prefix to force a non-EOF decode error in segment 1, verifying the cache reopens with the tip pinned at segment 0.
After the block-header tip is confirmed, load the persisted chainlock blob via `MetadataStorage::load_metadata` and decode it. If the chainlock's `block_height` is strictly above the block tip, or the blob fails to deserialize, clear it via `delete_metadata` and emit a warning. This prevents the chainlock manager from trusting a value the local header chain can no longer corroborate after a mid-cascade crash repair.
…ound worker The placement before `start_worker` is load-bearing: a stale tip persisted by the worker's first tick would clobber the sentinel-driven recovery. Add a comment so a future reader doesn't reorder the two calls.
…om client startup Add an async `clamp_heights_to(tip)` method on the `WalletInterface` trait with a default no-op so existing implementors compile unchanged. The `WalletManager` implementation iterates internal wallets and clamps both `last_processed_height` and `synced_height` to `min(current, tip)`. Call it from `DashSpvClient::new` after the storage layer's startup consistency check has settled the block-header tip, so a sentinel-driven repair cannot leave wallet metadata pointing above a height the local chain no longer contains.
Cover the new startup-repair surface: `highest_valid_tip` returns the full tip when the chain is intact and the start sentinel when broken, each invariant violation (filter header > block tip, filter > filter header tip, block above block tip) triggers the matching downstream truncation, a stale chainlock above the header tip is cleared, the sentinel branch truncates to the safe tip and clears the marker, and `WalletManager::clamp_heights_to` lowers both metadata fields when above the tip and is a no-op otherwise.
…paths, fix prose separator
- Move `use dashcore::ephemerealdata::chain_lock::ChainLock` from inside
`chainlock_forced_reorg_drives_cascade_for_lighter_branch` test fn to
`mod tests` top in `block_headers/manager.rs`; `BLSSignature` was already
present there.
- Add `use dashcore::{BlockHash, bls_sig_utils::BLSSignature}` and
`use std::path::{Path, PathBuf}` to `mod tests` in `consistency.rs`;
replace qualified `dashcore::BlockHash::all_zeros()`,
`dashcore::bls_sig_utils::BLSSignature::from(...)`, `std::path::Path`,
and `std::path::PathBuf` occurrences with the short forms.
- Add `use crate::network::NetworkRequest` to `mod tests` in
`chainlock/manager.rs`; replace `crate::network::NetworkRequest::...`
qualified match arm with `NetworkRequest::...`.
- Add `use std::slice` to `mod tests` in `fork_buffer.rs`; replace
`std::slice::from_ref(...)` with `slice::from_ref(...)`.
- Replace `std::sync::atomic::Ordering::SeqCst` (fully qualified, redundant
via `use super::*`) with `Ordering::SeqCst` in new `reorg.rs` tests.
- Fix prose separator `—` to `.` in `chainlock/manager.rs` comment.

There was a problem hiding this comment.
Startup consistency check has two real correctness gaps: filter-tip truncation aborts startup when filter headers are empty but filter storage starts above 0, and highest_valid_tip returns on the first valid parent link instead of walking the full sub-chain — both could let mid-cascade crash recovery silently leave inconsistent state.

- Replace `unwrap_or(0)` with `if let Some` in filter invariant check so absent filter headers do not trigger an invalid truncation below `start_height` - Correct `highest_valid_tip` docstring to accurately describe the single-link walk-back behavior instead of claiming full chain verification - Fix `highest_valid_tip` signature from `&self` to `&mut self` to match the write lock it acquires on the inner `SegmentCache` - Make `is_reorg_sentinel_set` async and use `tokio::fs::try_exists` to avoid blocking the Tokio executor with a synchronous `Path::exists` call - Deduplicate sentinel path construction in `DiskStorageManager` by adding `PersistentMetadataStorage::sentinel_path_for` and delegating - Downgrade sentinel clear failure in the reorg cascade from a propagated error to a logged error so a failed `clear_reorg_sentinel` after a successful cascade does not make the reorg appear to have failed - Queue corrupt segments for deletion in `load_or_new` so they are removed on the next `persist` instead of producing repeated warnings on every restart - Add compile-time assertion that `PROBE_WINDOW > MAX_REORG_DEPTH` - Extend sentinel test to populate downstream storages and assert they are truncated to the safe tip - Add `highest_valid_tip` test for a partially broken chain (valid through height N-1, disconnected at N) - Add PROBE_WINDOW boundary tests documenting the probe-window limitation

There was a problem hiding this comment.
Most previous concerns landed cleanly — sentinel async, path dedup, probe-window assert, broken-chain test, segment cleanup, and the unwrap_or(0) crash are all fixed. But the fix for the filter/no-filter-header crash swapped a crash for a silent no-op, and three reviewers independently flag that as leaving orphaned filter data unrepaired.

…torage sentinel truncation Addresses manki-review comments on PR #167 #167 (comment) #167 (comment)
…n startup Adds `SegmentCache::clear_all` and `FilterStorage::clear_all` so the consistency check can fully reset filter storage when filter headers are absent but filter segments exist. Without this the filter sync used `filter_tip_height` to skip re-downloading segments that could belong to a discarded chain. Addresses manki-review comment on PR #167 #167 (comment)

There was a problem hiding this comment.
The clear_all() repair is broken in a way the new test can't see: it only queues in-memory segments for deletion, so any node with more than ~2 filter segments will keep stale files on disk across restarts and the consistency check will spin forever. Two open threads (BIP157 memory scan, MetadataStorage ISP) and the wallet-clamp test are still unaddressed.

Multi-segment durability bug fixed by switching clear_all to iterate over the persisted segment ID range, and the new segments.rs test exercises the on-disk-only middle segment that the original test missed. The one new finding is a false positive — filter_tip_height returns StorageResult, not Option, so .unwrap() can't panic on empty storage.
Blocking unresolved review threads:
- [Blocker] Filter invariant truncates to height 0 when no filter headers exist, failing if filter storage starts above height 0 —
dash-spv/src/storage/consistency.rs:133 - [Warning] is_reorg_sentinel_set is synchronous while all other MetadataStorage methods are async —

There was a problem hiding this comment.
New consistency-check module lands with reasonable invariants but the wallet clamp path is fragile: a read guard held across a write-lock acquisition and a swallowed return value both warrant fixing before merge. Testing gaps around sentinel-empty-headers and BIP157 integrity paths remain.

Bind `get_tip_height` into a local so the `RwLockReadGuard` is dropped before the wallet write lock is acquired, preventing deadlock for future `WalletInterface` impls that touch block-header storage. Addresses manki review comment on PR #167 #167 (comment)
Ensures the `None` arm of the sentinel recovery match in `check_and_repair_consistency` clears the sentinel, so a subsequent startup with empty block-header storage does not loop into recovery. Addresses manki review comment on PR #167 #167 (comment)
…y infallible Makes the `()` return contract explicit so future `WalletInterface` implementors do not add silent error paths from inside the SPV client's startup clamp. Addresses manki review comment on PR #167 #167 (comment)

Summary
Implements #143 — Phase 3.5 of the #137 reorg work. Detects and recovers from crashes during the reorg cascade, and validates cross-storage invariants on every startup.
MetadataStoragegainsdelete_metadata, plus sentinel write/clear/probe primitives. Sentinel is a zero-byte file atmetadata/reorg_in_progress.datwritten viaatomic_writeimmediately before the reorg cascade'sgeneration.fetch_addand cleared after the lasttruncate_abovecompletes.storage::consistency::check_and_repair_consistencyruns at the end ofDiskStorageManager::new(before the background worker starts). It validatesfilter_header_tip <= block_header_tip,filter_tip <= filter_header_tip, and the block-storage tip (probed by 1024-height window). Any violation triggerstruncate_above(block_header_tip)+persiston the offending storage.header_hash_indexbackward fromtip_heightviaPersistentBlockHeaderStorage::highest_valid_tipand truncates all storages to that height before invariant checks run.SegmentCache::load_or_newis now corruption-tolerant: an unreadable segment truncates the cache to the last readable segment and logs a warning (matches the sentinel cascade philosophy).chainlock.block_height > block_header_tipviadelete_metadata(BEST_CHAINLOCK_KEY).WalletInterface::clamp_heights_to(tip)on the wallet trait, called fromlifecycle.rsafterinitialize_genesis_block.Closes #143.
