Summary: In secondary mode, it is possible that the secondary lists the primary's WAL directory, finds a WAL and tries to open it. It is possible that the primary deletes the WAL after secondary listing dir but before the secondary opening it. Then the secondary will fail to open the WAL file with a PathNotFound status. In this case, we can return OK without replaying WAL and optionally replay more MANIFEST. Test Plan (on my dev machine): Without this PR, the following will fail several times out of 100 runs. ``` ~/gtest-parallel/gtest-parallel -r 100 -w 16 ./db_secondary_test --gtest_filter=DBSecondaryTest.SwitchToNewManifestDuringOpen ``` With this PR, the above should always succeed.
