clawbot	f5902f4241	Strip metadata from processed images (closes #82) ... Every output is exported with govips' StripMetadata, so it carries no EXIF, XMP, IPTC or ICC profile, the orig format included: it is always re-encoded, and pixa never serves the source bytes. The image is turned upright with AutoRotate right after decoding, so dropping the orientation tag does not leave it rotated, and a requested size applies to the upright image. An image with an ICC profile is converted to sRGB before export, since clients show an image with no profile as sRGB. No setting turns this off. README.md documents it.

clawbot	b3e59e7855	Test that processed images carry no metadata (closes #82) ... Failing tests first: GPS EXIF must not survive into any output format, an image with EXIF orientation 6 must come out upright (also when only a width is asked for), and a Display P3 image must come out as sRGB with no ICC profile. Three JPEG fixtures of about 1 KB each are added under internal/imageprocessor/testdata/. Model: opus-5-5	2026-09-28 23:49:39 +00:00
clawbot	04b5db6fbf	next -&gt; main (1.0.0 milestone) (#105) ... Accumulating milestone branch. One squashed commit per closed issue; `next` is kept green and mergeable to `main` at any time without notice. Landed so far: - `chore: update golangci-lint to v2.12.2 with canonical config` (#54) — canonical v2-schema `.golangci.yml`, pins bumped in `Dockerfile` and `script/bootstrap`, tree at `0 issues.`. Three behaviour deltas are recorded in that PR's body: `Cache.StoreVariant` takes a context, `MetadataStorage.Store` no longer leaks temp files on failure, and the `signing_key` too-short error text gained a `value too short:` prefix. Sequencing for the milestone is tracked in #103. Reviewed-on: #105 Co-authored-by: clawbot <clawbot@noreply.example.org>	2026-09-21 09:31:54 +02:00
3 people	55a609dd77	Bound imageprocessor.Process input read to prevent unbounded memory use (#37) ... closes #31 ## Problem `ImageProcessor.Process` used `io.ReadAll(input)` without any size limit, allowing arbitrarily large inputs to exhaust all available memory. This is a DoS vector — even though the upstream fetcher has a `MaxResponseSize` limit (50 MiB), the processor interface accepts any `io.Reader` and should defend itself independently. Additionally, the service layer's `processFromSourceOrFetch` read cached source content with `io.ReadAll` without a bound, so an unexpectedly large cached file could also cause unbounded memory consumption. ## Changes ### Processor (`processor.go`) - Added `maxInputBytes` field to `ImageProcessor` (configurable, defaults to 50 MiB via `DefaultMaxInputBytes`) - `NewImageProcessor` now accepts a `maxInputBytes` parameter (0 or negative uses the default) - `Process` now wraps the input reader with `io.LimitReader` and rejects inputs exceeding the limit with `ErrInputDataTooLarge` - Added `DefaultMaxInputBytes` and `ErrInputDataTooLarge` exported constants/errors ### Service (`service.go`) - `NewService` now wires the fetcher's `MaxResponseSize` through to the processor - Extracted `loadCachedSource` helper method to flatten nesting in `processFromSourceOrFetch` - Cached source reads are now bounded by `maxResponseSize` — oversized cached files are discarded and re-fetched ### Tests (`processor_test.go`) - `TestImageProcessor_RejectsOversizedInputData` — verifies that inputs exceeding `maxInputBytes` are rejected with `ErrInputDataTooLarge` - `TestImageProcessor_AcceptsInputWithinLimit` — verifies that inputs within the limit are processed normally - `TestImageProcessor_DefaultMaxInputBytes` — verifies that 0 and negative values use the default - All existing tests updated to use `NewImageProcessor(0)` (default limit) Co-authored-by: user <user@Mac.lan guest wan> Co-authored-by: clawbot <clawbot@eeqj.de> Reviewed-on: #37 Co-authored-by: clawbot <clawbot@noreply.example.org> Co-committed-by: clawbot <clawbot@noreply.example.org>	2026-03-20 07:01:15 +01:00
