chore(deps): consume upstream govips, drop antst fork - #74

Draft
Conversation
The streaming I/O this service depends on was upstreamed in davidbyttow/govips#539 (which landed our #530 with authorship preserved) and #540, so the replace directive is no longer needed. Verified upstream is a strict superset of the pinned fork commit (be0d764): the exported API diff is empty, and every non-comment line the fork added to vips/ is either verbatim upstream or accounted for by upstream's refactor of the export-param mapping into shared *ParamsFromExport helpers. The only fork-side deletion is dead code (save_tiff_to_target — both versions take the buffered path for TIFF, since libtiff needs seekable output). Upstream also carries two robustness fixes on top of the fork: sourceRead now bounds retries on a pathological (0, nil) reader instead of spinning inside the cgo callback, and takeErr clears the error it takes rather than letting a stale one resurface. Streaming is not yet in a tagged release (v2.18.0 predates the merge), so this pins an upstream master pseudo-version; move to v2.19.0 once tagged. go mod tidy also pruned go.sum entries that only existed to satisfy the fork's own go.mod — no require version changed. Verified: go build ./... and -tags vips, go test -tags vips ./... (12/12 packages), golangci-lint run clean.

Synchronize all active documentation with the upstream dependency.
The dependency migration is recorded, but several active sections still describe the antst fork or the old v2.18.0 dependency.

Fix the Markdown heading parse.
Line 29 starts with #540 without a space. Keep the issue references on the same prose line or indent the continuation so Markdown does not parse it as an atx heading.

Summary
The streaming I/O this service depends on was upstreamed in davidbyttow/govips#539 — which landed our #530 with authorship preserved — plus follow-up #540. The
replacedirective pointing atantst/govipsis no longer needed.Why this is safe
Upstream is a strict superset of the pinned fork commit (
be0d764):vipspackage exists upstream with unchanged signatures — including all seven symbols this service uses (LoadImageFromReader,SetStreamDiscThreshold,SetStreamScratchDir,SetPipeReadLimit, plus stock APIs).vips/*.{go,c,h}is either verbatim upstream or accounted for by upstream's refactor of the inline export-param mapping into shared*ParamsFromExporthelpers.transcode.gois byte-identical;govips.goidentical;image.godiffers only by a doc comment.save_tiff_to_targetinstream.c. Both versions take the buffered early-return path for TIFF (libtiff requires seekable output), so it was never called.What we gain
Two real robustness fixes on our streaming path:
sourceReadbounds retries on a pathological(0, nil)reader — the fork's unboundedfor {}can spin forever inside a cgo callback, pinning a libvips worker thread.takeErrnow actually clears the error it takes, so a stale error can't resurface on a later call.Plus sub-format sniffing for streamed AVIF/BMP/PSD (#540 — relevant to 019 if we ever read
Format()on the streaming path), typedSaveToWriterJpeg/Png/Webp/Tiff/Heif/Gifvariants, BigTIFF detection, WebPTargetSizeversion guard, greyscale background fix.Caveat
Streaming is not yet in a tagged release —
v2.18.0(2026-04-01) predates the merge and there's been no tag since. This pins an upstream master pseudo-version. Still strictly better than the fork: noreplace, so Renovate can now see and bump it. Move tov2.19.0once tagged.go mod tidyalso prunedgo.sumentries that only existed to satisfy the fork's owngo.mod(chi 5.3.0, nats-server 2.14.2, olderx/crypto/x/net/x/sync/x/sys/x/text) — pure removals, norequireversion changed.Docs
