sneak	018c12a8d2	Count hits, misses, fetches and transforms as Prometheus counters (closes #311) ... The five counts the cache_stats table held are now Prometheus counters in memory, as fields of the cache. NewCache makes them and registers them on the registry it is given. pixad gives it Prometheus' default registry, which /metrics serves; each test gives it a new one. The Increment methods add to their cache's counters, so counting makes no database call. cache_stats, Cache.Stats, Service.Stats, CacheStats and the pending counts are gone, with their tests. The background goroutine now writes only access times, and its names say so: StartPendingAccessTimeWrites, StopPendingAccessTimeWrites and pendingaccesstimes.go. The two stop tests whose write under way was a count now use access times. Model: opus-5-5	2026-10-26 09:12:33 +00:00
clawbot	ca512fdb4f	Remove the unused cache lifetime setting (closes #69) ... CacheConfig.CacheTTL was set to DefaultCacheTTL (24 hours) and never read, so cached images never expired. Remove the field, the constant and the line that set it. Cached source and transformed images stay until eviction removes them to keep the cache within cache_max_bytes. A new test caches a source and a transformed image, sets every time pixa stores for them two days back (database rows, metadata files and file times), and checks that both are still served from the cache without a new upstream fetch. Existing tests lose only the CacheTTL line of their cache config. Model: opus-5-5	2026-10-13 07:58:55 +02:00
clawbot	8314099abd	Refuse image requests whose Referer is on referer_blocklist (closes #90) ... A new setting, referer_blocklist (PIXA_REFERER_BLOCKLIST), lists hosts whose pages may not show pixa's images. Entries are written and matched as allowlist_hosts are, with the same matcher. Both image routes check the Referer before the signature, the cache and the upstream fetch, and answer 403 with the JSON error, so a blocked request costs nothing and is refused whether or not the image is cached. No Referer, or one that does not parse, is served; README.md says this makes the list easy to get around. An entry of either host list that is not a host name (letters, digits, hyphens, underscores, dots, at most one leading dot) or an IP address now aborts startup naming the setting and the entry.
