Revision 8c7eb59838086b4c368b3d39daa91dcec57ea55e authored by Maysam Yabandeh on 27 April 2019, 00:26:29 UTC, committed by Facebook Github Bot on 27 April 2019, 00:30:30 UTC
Summary: The newly added test CompactionJobTest.SnapshotRefresh sets the snapshot refresh period to 0 to stress the feature. This results into large number of refresh events, which in turn results into an UBSAN failure when a bitwise shift operand goes beyond the uint64_t size. The patch fixes that by simplifying the shift logic to be done only by 2 bits after each refresh. Furthermore it verifies that the shift operation does not result in decreasing the refresh period. Testing: COMPILE_WITH_UBSAN=1 make -j32 compaction_job_test ./compaction_job_test --gtest_filter=CompactionJobTest.SnapshotRefresh Pull Request resolved: https://github.com/facebook/rocksdb/pull/5257 Differential Revision: D15106463 Pulled By: maysamyabandeh fbshipit-source-id: f2718898ea7ba4fa9f7e87b70cf98fe647c0de80
