22 hours	Let go of a slot lock that cannot take its key	Bryce Kwon	-0/+15
	A failed truncate or key write returned with the descriptor still open, so the lock was held while the page rendered uncached and the file was left behind. It is removed before its last close, as every holder does.
22 hours	Keep lock contention out of the error log	Bryce Kwon	-2/+20
	process_slot logged every failure to lock, so each request that found its slot being filled left a line, while refresh_slot logged none, so an expired slot in a directory the server cannot write was served stale for good without a word. lock_slot now logs the step that failed, as the scan does, and leaves out only another request at work.
22 hours	Lock the cached repolist with flock	Bryce Kwon	-0/+38
	The slot lock has to be an flock, since an exec filter drops a record lock when it closes the stdout a fill writes through. The scan only got by with fcntl because nothing reopens its file while it runs. One kind of lock lets the two share their code, and on Linux, where the kinds never see each other, an flock on the scan's file now holds a scan off like any other.
22 hours	Open the lock files close-on-exec	Bryce Kwon	-0/+27
	Each exec filter and snapshot compressor a fill runs inherited the slot's lock descriptor beside the stdout it writes into. An flock lasts until its last copy closes and nothing waits for a process a filter leaves behind, so a fill killed before its rename could leave the slot locked, and served stale or uncached, for as long as such a process lived. The scan holds its lock across no exec and opens the same way so that the two stay alike.
22 hours	Tidy the cache test's helpers and outputs	Bryce Kwon	-24/+18
	The header's last sentence named two of the many later subjects, so it goes too. The second request's stderr is still kept, for the lock tests that come next.
22 hours	Use test_dir_is_empty for the empty cache checks	Bryce Kwon	-16/+8
	The library's check also lists whatever was left behind when it fails.
2026-10-17	Lock a cache slot with flock	Bryce Kwon	-0/+38
	The slot lock was a POSIX record lock, which a process loses the moment any descriptor on the file closes, and the fill puts the lock file on stdout, which every exec filter and snapshot compressor closes with its dup2. A second request on the slot could then rebuild it under the first and splice the two pages. An flock holds until the last descriptor goes.
2026-10-17	Abandon a fill whose last flush fails to write	Bryce Kwon	-0/+16
	The slot being filled was forgotten before the page's final flush, so a write that failed there, on a full disk for one, could not abandon the fill: cgit died into the lock file instead and the visitor got nothing. The mid-page path already delivered the page from the lock file.
2026-10-16	Compare the cached page with the uncached one whole	Bryce Kwon	-5/+1
	The footer lost the time it was generated at in 2018, and both runs come from the same binary, so the two pages have nothing to differ in.
2026-10-16	Cache every branch page under cache-dynamic-ttl	Bryce Kwon	-0/+19
	The dynamic ttl only applied when the url named a branch with h=, so the log, tree and refs of the default branch, which never carry one, fell back to cache-summary-ttl. The manual already gives each ttl the scope the code now uses.
2026-10-01	Keep clone files and oversized responses out of the cache	Bryce Kwon	-0/+43
	The dumb transport reads files that already sit on the disk, so a pack copied into a slot cost that disk twice and the request a second write of every byte. A snapshot took a slot whatever its size, so a visitor naming distinct refs and ids could fill the cache root with archives. `cache-max-slot-size`, 64 MB unless set, now serves a larger response from the lock file and drops it, along with any expired copy it would have replaced.
