Summary: Relating to #1903: In MaybeFlushColumnFamilies() we want to modify the 'getting_flushed' flag before releasing the db mutex when SwitchMemtable() is called. The following 2 actions need to be atomic in MaybeFlushColumnFamilies() - getting_flushed is false on oldest log - we determine that all CFs can be flushed to successfully release oldest log - we set getting_flushed = true on the oldest log. ------- - getting_flushed is false on oldest log - we determine that all CFs can NOT be flushed to successfully release oldest log - we set unable_to_flush_oldest_log_ = true on the oldest log. #### In the 2pc case: T1 enters function but is unable to flush all CFs to release log T1 sets unable_to_flush_oldest_log_ = true T1 begins flushing all CFs possible T2 enters function but is unable to flush all CFs to release log T2 sees unable_to_flush_oldes_log_ has been set so exits T3 enters function and will be able to flush all CFs to release oldest log T3 sets getting_flushed = true on oldes Closes https://github.com/facebook/rocksdb/pull/1909 Differential Revision: D4646235 Pulled By: reidHoruff fbshipit-source-id: c8d0447
