fscache's Remove drops the in-memory entry, releases the lock, and only then unlinks - blocking until every outstanding reader closes. A Get landing in that window re-creates the file at the same path under a fresh entry, and the deferred unlink deletes those new bytes. The entry survives pointing at nothing, and since a present entry is treated as a hit, every later Get for that key returns ENOENT for the rest of the process's life. Only a restart, which rebuilds the map from disk, cleared it. Get now drops such an entry and retries once, so a vanished data file costs one re-fetch instead of poisoning the key permanently. This also covers a file disappearing for reasons unrelated to that race, such as external deletion or a restored backup. Specs cover an in-process entry, one adopted at startup, and the deferred-removal race itself. |
