Replace .golangci.yml with the canonical v2-schema config
(default: all minus six disabled linters, lll 88, tests included)
and bump every golangci-lint pin to v2.12.2:
- Dockerfile: golangci/golangci-lint:v2.12.2-alpine (hash-pinned)
- script/bootstrap: GOLANGCI_LINT_VERSION 2.12.2 with new
linux-amd64/arm64 release-archive sha256 pins
Fix all 747 findings the stricter config surfaces, with no behavior
changes: t.Parallel() throughout the test suite, static sentinel
errors and errors.Is comparisons, checked error returns, context
propagation (contextcheck/noctx), 88-column wrapping, extracted
constants and helpers for goconst/dupl/funlen/cyclop, exhaustive
switch cases replicating existing defaults, and white-box test files
renamed to *_internal_test.go for testpackage. Three
nolint:tagliatelle directives preserve the existing snake_case JSON
wire and on-disk metadata formats.
The golangci-lint binary was hardcoded as linux-amd64, causing Docker builds
to fail on arm64 hosts. The amd64 ELF binary cannot execute on aarch64,
producing a misleading shell syntax error during make check.
Use uname -m to detect the container architecture at build time and download
the matching binary. Both amd64 and arm64 SHA-256 hashes are pinned.
Closes#15
- Update Dockerfile base image from golang:1.24-alpine to golang:1.25.4-alpine
(pinned by sha256 digest) to match go.mod requirement of go >= 1.25.4
- Fix gosec G703 (path traversal) false positives by adding filepath.Clean()
at call sites with nolint annotations for internally-constructed paths
- Fix gosec G704 (SSRF) false positive with nolint annotation; URL is already
validated by validateURL() which checks scheme, resolves DNS, and blocks
private IPs
- All make check passes clean (lint + tests)
- Add config validation: signing_key required, minimum 32 characters
- Server now fails to start without valid signing_key (no more runtime errors)
- Add config.example.yml with default whitelist hosts
- Copy config to /etc/pixa/config.yml in Docker image
- Update entrypoint to use --config /etc/pixa/config.yml
- Add config.dev.yml for local Docker development
- Mount dev config in make devserver
- Change default StateDir from ./data to /var/lib/pixa (proper Unix convention)
- Create directory owned by pixad user in Dockerfile
- Set WORKDIR to /var/lib/pixa
- Replace gen2brain/avif, gen2brain/webp, disintegration/imaging with govips
- govips uses libvips via CGO for fast native image processing
- Add libheif-dev to Dockerfile for AVIF support
- Add docker-test Makefile target for running tests in Docker
- Update processor.go to use vips API for decode, resize, encode
- Add TestMain to initialize/shutdown vips in tests
- Remove WASM-based libraries (gen2brain) in favor of native codecs
Performance improvement: AVIF encoding now uses native libheif instead of
WASM, significantly reducing encoding time for large images.
- Build stage: golang:1.24-alpine with vips-dev for CGO image libs
- Runtime stage: alpine:3.21 with vips runtime only
- Pass VERSION build arg for ldflags embedding
- Add 'make docker' target to build image with git version
