Revision 4f6c86226ce79e3d4e35acb8f82b4a54d1d71c32 authored by Sagar Vemuri on 28 January 2020, 03:57:32 UTC, committed by Facebook Github Bot on 28 January 2020, 03:58:53 UTC
Summary:
./db_compaction_test DBCompactionTest.LevelTtlCascadingCompactions passed 96 / 100 times.
```
With the fix: all runs (tried 100, 1000, 10000) succeed.
```
$ TEST_TMPDIR=/dev/shm ~/gtest-parallel/gtest-parallel ./db_compaction_test --gtest_filter=DBCompactionTest.LevelTtlCascadingCompactions --repeat=1000
[1000/1000] DBCompactionTest.LevelTtlCascadingCompactions (1895 ms)
```
Test Plan:
Build:
```
COMPILE_WITH_TSAN=1 make db_compaction_test -j100
```
Without the fix: a few runs out of 100 fail:
```
$ TEST_TMPDIR=/dev/shm KEEP_DB=1 ~/gtest-parallel/gtest-parallel ./db_compaction_test --gtest_filter=DBCompactionTest.LevelTtlCascadingCompactions --repeat=100
