Summary: We recently noticed that some memtable flushed and file ingestions could proceed during LockWAL, in violation of its stated contract. (Note: we aren't 100% sure its actually needed by MySQL, but we want it to be in a clean state nonetheless.) Despite earlier skepticism that this could be done safely (https://github.com/facebook/rocksdb/issues/12666), I found a place to wait to wait for LockWAL to be cleared before allowing these operations to proceed: WaitForPendingWrites() Pull Request resolved: https://github.com/facebook/rocksdb/pull/12652 Test Plan: Added to unit tests. Extended how db_stress validates LockWAL and re-enabled combination of ingestion and LockWAL in crash test, in follow-up to https://github.com/facebook/rocksdb/issues/12642 Ran blackbox_crash_test for a long while with relevant features amplified. Suggested follow-up: fix FaultInjectionTestFS to report file sizes consistent with what the user has requested to be flushed.
