2023-07-11	cache: 'file-expiration-time' uses 'lstat', not 'stat'.	Ludovic Courtès
	Fixes a bug whereby 'cached-channel-instance' would potentially consider cache entries obsolete too early because they refer to items in the store, which is mounted as 'noatime' on Guix System. * guix/cache.scm (file-expiration-time): Use 'lstat' and 'false-if-exception' rather than 'stat'. This matches what (guix scripts shell) does.
2022-06-04	cache: Catch invalid 'last-expiry-cleanup'.	zimoun
	Fixes <http://issues.guix.gnu.org/55638>. * guix/cache.scm (maybe-remove-expired-cache-entries)[last-expiry-date]: Use 'get-string-all' + 'string->number' instead of 'read'; ignore invalid numbers. * tests/cache.scm ("maybe-remove-expired-cache-entries, empty cache") ("maybe-remove-expired-cache-entries, corrupted cache"): New tests. Co-authored-by: Ludovic Courtès <ludo@gnu.org>

2021-01-13	git: Periodically delete least-recently-used cached checkouts.	Ludovic Courtès

(update-cached-checkout)[cache-entries]: New procedure. Add call to 'maybe-remove-expired-cache-entries'. * guix/cache.scm (file-expiration-time): Add optional 'timestamp' parameter and honor it.
