Title: The order of two operations in asyncLock()
Status: Closed Type: Code_Defect
Severity: Important Priority: Immediate
Subsystem: Extensions Resolution: Overcome_By_Events

Description:
In file sqlite3async.c, the function asyncLock(), line 888 Why set the lock.eLock and lock.eAsyncLock before getFileLock() is called? If getFileLock() failed, why not reset the eLock and eAsyncLock? It looks like if the first asyncLock() called failed, the second will succeed without any check?

We no longer support the async extension. The features provided by async is now provided in a much better way by WAL mode.
