Summary
In PR #13074 , we added a logic to prevent stale OPTIONS file from getting deleted by
PurgeObsoleteFiles()if the OPTIONS file is being referenced by any of the scheduled the remote compactions.PurgeObsoleteFiles()was not the only place that we were cleaning up the old OPTIONS file. We've been also directly cleaning up the old OPTIONS file as part ofSetOptions():RenameTempFileToOptionsFile()->DeleteObsoleteOptionsFiles()unless FileDeletion is disabled.This was not caught by the UnitTest because we always preserve the last two OPTIONS file. A single call of
SetOptions()was not enough to surface this issue in the previous PR.To keep things simple, we are just skipping the old OPTIONS file clean up in
RenameTempFileToOptionsFile()if remote compaction is enabled. We letPurgeObsoleteFiles()clean up the old options file later after the compaction is done.Test Plan
Updated UnitTest to reproduce the scenario. It's now passing with the fix.
