[Bug] VFS IDBBatchAtomicVFS has error in locks

[khanhicetea]

When I switched from OPFS VFS into IDBBatchAtomicVFS, the weird bug happen

So I'm curious this is upstream bug ? Which one VFS you commonly use ?

FYI : I ran IDBBatchAtomicVFS in SharedWorker (I want to switch IDBBatchAtomicVFS because OPFS can't run in SharedWorker)

Maybe the upstream bug, the code in the playground works well. Can you provide a reproduction?

Maybe it related to this upstream issue : rhashimoto/wa-sqlite#258

My guess is this one, which is fixed but doesn't appear to have been merged into the fork.

[edit] Or maybe not, as the fix is in jUnlock(), not jLock().

@rhashimoto he use your upstream lib v1.0.8 https://github.com/subframe7536/sqlite-wasm/blob/main/package.json#L93

I can't make a fast re-production because the db schema is big, it runs normal without issues in CoopSyncOPFS.
So the different points : VFS, SharedWorker instead of Worker (open 1 tab has issue so don't relate to multi connections thing)

Btw thanks @rhashimoto for helping
