Summary: We recently saw a case in crash test in which a WAL file in the middle of the list of live WALs was not included in the backup, so the DB was not openable due to missing WAL. We are not sure why, but this change should at least turn that into a backup-time failure by ensuring all the WAL files expected by the manifest (according to VersionSet) are included in `GetSortedWalFiles()` (used by `GetLiveFilesStorageInfo()`, `BackupEngine`, and `Checkpoint`) Related: to maximize the effectiveness of track_and_verify_wals_in_manifest with GetSortedWalFiles() during checkpoint/backup, we will now sync WAL in GetLiveFilesStorageInfo() when track_and_verify_wals_in_manifest=true. Pull Request resolved: facebook#10083 Test Plan: added new unit test for the check in GetSortedWalFiles() Reviewed By: ajkr Differential Revision: D36791608 Pulled By: pdillinger fbshipit-source-id: a27bcf0213fc7ab177760fede50d4375d579afa6
…acebook#10185) Summary: `FlushWAL(true /* sync */)` is used internally and for manual WAL sync. It had a bug when used together with `track_and_verify_wals_in_manifest` where the synced size tracked in MANIFEST was larger than the number of bytes actually synced. The bug could be repro'd almost immediately with the following crash test command: `python3 tools/db_crashtest.py blackbox --simple --write_buffer_size=524288 --max_bytes_for_level_base=2097152 --target_file_size_base=524288 --duration=3600 --interval=10 --sync_fault_injection=1 --disable_wal=0 --checkpoint_one_in=1000 --max_key=10000 --value_size_mult=33`. An example error message produced by the above command is shown below. The error sometimes arose from the checkpoint and other times arose from the main stress test DB. ``` Corruption: Size mismatch: WAL (log number: 119) in MANIFEST is 27938 bytes , but actually is 27859 bytes on disk. ``` Pull Request resolved: facebook#10185 Test Plan: - repro unit test - the above crash test command no longer finds the error. It does find a different error after a while longer such as "Corruption: WAL file 481 required by manifest but not in directory list" Reviewed By: riversand963 Differential Revision: D37200993 Pulled By: ajkr fbshipit-source-id: 98e0071c1a89f4d009888512ed89f9219779ae5f
Summary: With facebook#10087, applications calling `SyncWAL()` or writing with `WriteOptions::sync=true` can suffer from performance regression. This PR reverts to original behavior of tracking the syncing of closed WALs. After we revert back to old behavior, recovery, whether kPointInTime or kAbsoluteConsistency, may fail to detect corruption in synced WALs if the corruption is in the live WAL.
