clawbot	880845f38c	Check cached sources with upstream after the cache TTL (closes #69) ... A cached image was served until eviction, so a change at the same URL was never picked up. After 24 hours a request checks the source with upstream, sending its stored ETag and Last-Modified. A 304 renews it with no download or conversion. New bytes replace it, and older variants are converted again. A failed check serves the cached image and puts the URL in the negative cache. Images not checked for 30 days are evicted. Variant rows keep the source's ETag and Last-Modified, so a variant whose source was evicted is checked the same way. A variant file's modification time is its source's check time when it was made or renewed, so a hit reads no database row. Model: opus-5-5	2026-11-11 10:38:51 +00:00
clawbot	b73bbde46e	Detect a fetched image's format from its bytes once (closes #319) ... magic.DetectFormat returns an imagerequest.Format. ValidateMagicBytes returns the format it checked against the upstream Content-Type. The cache reads a cached source's format from its file's first bytes, as it reads a variant's. The proxy hands the format to Process. Process refuses a format that is not a source format, and input libvips would load with another loader, such as an SVG passing as AVIF. Format.MIMEType declares each MIME string once, and the fetcher, the cache's variant read and the Accept matching use it. magic.MIMEType, magic.ImageFormat, MIMEToImageFormat, magic's SVG detection, detectFormat, formatFromString, FormatToMIME and Result.InputFormat are gone.

clawbot	17376d885b	Split internal/imgcache into the image proxy and the cache (closes #317) ... The new package internal/imageproxy holds Proxy, which was imgcache.Service, with its Config, ImageResponse, CacheStatus and errors. imageproxy.New makes and registers the counters of upstream fetches and transforms. internal/imgcache holds the cache only, with its hit and miss counters, and imgcache.CacheConfig is imgcache.Config. The cache reads and writes each kind it keeps with one pair of methods: Variant and PutVariant, Source and PutSource, Failure and PutFailure. Source replaces LookupSource followed by GetSourceContent. imgcache.go and module.go are gone. The proxy's tests moved with it. The cache's tests check that the reconciliation pass removes an empty or cut file and its row. The proxy's tests remove them by hand, then check that Get fetches or converts again.
