From afc16ab5a060b16c9cd609d8fa198dee0e740e1e Mon Sep 17 00:00:00 2001 From: ci-check Date: Sun, 25 Oct 2026 04:32:54 +0800 Subject: [PATCH 1/6] fix: run large-db integrity quick_check off the pre-listen critical path (#4609) A 14 GB index.db took 260 s for PRAGMA quick_check inside UnifiedStore.open, always exceeding the launcher's hard 60 s spawn budget: the child was killed while still scanning and the host stayed on direct (uncompressed) for its whole lifetime, with every retry failing identically. Three-lane decision at open: - unchanged since a passing check (size+mtime fingerprint in index.db.quickcheck) -> skip; - <= 256 MiB -> inline check exactly as before (typed throw, shadow quarantine + retry-once); now stamps the fingerprint on pass; - > 256 MiB -> bind first, scan in a background worker thread with a readonly second connection (both engines are sync-only APIs; running it inline would move the freeze onto live traffic). A deferred failure disables unified reads for the process lifetime (JSON envelopes remain the recovery source), writes an index.db.quarantine-pending marker, and the NEXT open quarantines the file set before opening fresh (no live handle -> no Windows EBUSY). An inconclusive worker death records nothing and retries next open. BILI_STORAGE_QUICK_CHECK=0 still skips everything. No new config surface. --- src/storage/quick-check-worker.ts | 132 ++++++++++++++++++ src/storage/shadow.ts | 45 +++--- src/storage/store.ts | 223 ++++++++++++++++++++++++++---- 3 files changed, 356 insertions(+), 44 deletions(-) create mode 100644 src/storage/quick-check-worker.ts diff --git a/src/storage/quick-check-worker.ts b/src/storage/quick-check-worker.ts new file mode 100644 index 0000000000..41f04f96f8 --- /dev/null +++ b/src/storage/quick-check-worker.ts @@ -0,0 +1,132 @@ +/** + * #4609: deferred integrity check for large index.db files. + * + * quick_check is O(db size) — 14 GB took 260 s in the field (#4609) — and both + * engines expose only synchronous APIs, so running it on the main thread + * post-listen would just move the multi-minute event-loop freeze onto live + * traffic.
