Yanqin Jin d47c871190 Fix data race to VersionSet::io_status_ (#7034) ... Summary: After https://github.com/facebook/rocksdb/issues/6949 , VersionSet::io_status_ can be concurrently accessed by multiple threads without lock, causing tsan test to fail. For example, a bg flush thread resets io_status_ before calling LogAndApply(), while another thread already in the process of LogAndApply() reads io_status_. This is a bug. We do not have to reset io_status_ each time we call LogAndApply(). io_status_ is part of the state of VersionSet, and it indicates the outcome of preceding MANIFEST/CURRENT files IO operations. Its value should be updated only when: 1. MANIFEST/CURRENT files IO fail for the first time. 2. MANIFEST/CURRENT files IO succeed as part of recovering from a prior failure without process restart, e.g. calling Resume(). Test Plan (devserver): COMPILE_WITH_TSAN=1 make check COMPILE_WITH_TSAN=1 make db_test2 ./db_test2 --gtest_filter=DBTest2.CompactionStall Pull Request resolved: https://github.com/facebook/rocksdb/pull/7034 Reviewed By: zhichao-cao Differential Revision: D22247137 Pulled By: riversand963 fbshipit-source-id: 77b83e05390f3ee3cd2d96d3fdd6fe4f225e3216		4 years ago
