🐛 OCPBUGS-76453: clean up orphaned temp dirs in catalog storage - #2537
Conversation
LocalDirV1.Store creates a temp dir (.{catalog}-{random}) and renames it
into place atomically. If the process is interrupted before the deferred
RemoveAll runs, the temp dir persists. Each restart adds another, eventually
filling the disk.
Primary fix: remove any matching temp dirs at the start of Store before
creating a new one. Since Store holds the write mutex, any dirs found are
guaranteed to be from a previous run.
Defense-in-depth: add /var/cache/catalogs to GarbageCollector's list of
scanned paths (CachePath string -> CachePaths []string), so orphaned temp
dirs are also removed by the periodic GC cycle.

Pull request overview
This PR addresses orphaned temporary directories left behind when LocalDirV1.Store is interrupted before its deferred cleanup runs, preventing disk usage from growing across restarts. It also extends periodic garbage collection so it can clean orphaned temp dirs under catalog storage in addition to the unpack cache.
Changes:
- Clean up any leftover
.{catalog}-*temp directories at the start ofLocalDirV1.Store. - Update
GarbageCollectorto support scanning multiple cache directories (CachePath→CachePaths) and include the catalog storage directory in catalogd’s GC configuration. - Add unit tests covering both the
Storecleanup behavior and GC cleanup of orphaned temp dirs in the storage path.
