Summary: We are seeing WAL corruption in crash tests where wal_compression and recycled_wal are enabled. With wal_compression, we write a SetCompression record when creating a WAL, which can happen during DB open time. Our current stress test set up may write directly to the underlying WAL file during DB open, while writing to a buffer under TestFSWritableFile later for sync fault injection. This causes the last synced position to be inaccurately tracked in TestFSWritableFile and causes reads to return incorrect data. This PR removes the line that causes this mixture of WAL writes. Also updated TestFSWritableFile to avoid such a mixture of buffered and direct writes. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12834 Test Plan: the following command repros WAL corruption before this PR ``` ./db_stress --WAL_size_limit_MB=0 --WAL_ttl_seconds=60
