* Fix Get does not return super version on error Summary: This is caught when I was testing facebook#2886. Closes facebook#2907 Differential Revision: D5863153 Pulled By: yiwu-arbug fbshipit-source-id: 8c54759ba1a0dc101f24ab50423e35731300612d * fix data race Summary: Fix a TSAN failure in `DBRangeDelTest.ValidLevelSubcompactionBoundaries`: https://gist.github.com/miasantreble/712e04b4de2ff7f193c98b1acf07e899 Closes facebook#3691 Differential Revision: D7541400 Pulled By: miasantreble fbshipit-source-id: b0b4538980bce7febd0385e61d6e046580bcaefb * check return status for Sync() and Append() calls to avoid corruption Summary: Right now in `SyncClosedLogs`, `CopyFile`, and `AddRecord`, where `Sync` and `Append` are invoked in a loop, the error status are not checked. This could lead to potential corruption as later calls will overwrite the error status. Closes facebook#3740 Differential Revision: D7678848 Pulled By: miasantreble fbshipit-source-id: 4b0b412975989dfe80348f73217b9c4122a4bd77 * Fix race condition between log_.erase and log_.back Summary: log_ contract specifies that it should not be modified unless both mutex_ and log_write_mutex_ are held. log_.erase however does that with only holding mutex_. This causes a race condition with two_write_queues since logs_.back is read with holding only log_write_mutex_ (which is correct according to logs_ contract) but logs_.erase is called concurrently. This is probably the cause of logs_.back returning nullptr in facebook#3852 although I could not reproduce it. Fixes facebook#3852 Closes facebook#3859 Differential Revision: D8026103 Pulled By: maysamyabandeh fbshipit-source-id: ee394e00fe4aa520d884c5ef87981e9d6b5ccb28 * Sync CURRENT file during checkpoint (facebook#4322) Summary: For the CURRENT file forged during checkpoint, we were forgetting to `fsync` or `fdatasync` it after its creation.
