Closes [issue #50](#50) ## Summary Refactors the Dockerfile to use a separate lint stage with a pinned golangci-lint Docker image, following the pattern used by [sneak/pixa](https://git.eeqj.de/sneak/pixa). This replaces the previous approach of installing golangci-lint via curl in the builder stage. ## Changes ### Dockerfile - **New `lint` stage** using `golangci/golangci-lint:v2.11.3` (Debian-based, pinned by sha256 digest) as a separate build stage - **Builder stage** depends on lint via `COPY --from=lint /src/go.sum /dev/null` — build won't proceed unless linting passes - **Go bumped** from 1.24 to 1.26.1 (`golang:1.26.1-bookworm`, pinned by sha256) - **golangci-lint bumped** from v1.64.8 to v2.11.3 - All three Docker images (golangci-lint, golang, alpine) pinned by sha256 digest - Debian-based golangci-lint image used (not Alpine) because mattn/go-sqlite3 CGO does not compile on musl (off64_t) ### Linter Config (.golangci.yml) - Migrated from v1 to v2 format (`version: "2"` added) - Removed linters no longer available in v2: `gofmt` (handled by `make fmt-check`), `gosimple` (merged into `staticcheck`), `typecheck` (always-on in v2) - Same set of linters enabled — no rules weakened ### Code Fixes (all lint issues from v2 upgrade) - Added package comments to all packages - Added doc comments to all exported types, functions, and methods - Fixed unchecked errors flagged by `errcheck` (sqlDB.Close, os.Setenv in tests, resp.Body.Close, fmt.Fprint) - Fixed unused parameters flagged by `revive` (renamed to `_`) - Fixed `gosec` G120 warnings: added `http.MaxBytesReader` before `r.ParseForm()` calls - Fixed `staticcheck` QF1012: replaced `WriteString(fmt.Sprintf(...))` with `fmt.Fprintf` - Fixed `staticcheck` QF1003: converted if/else chain to tagged switch - Renamed `DeliveryTask` → `Task` to avoid package stutter (`delivery.Task` instead of `delivery.DeliveryTask`) - Renamed shadowed builtin `max` parameter to `upperBound` in `cryptoRandInt` - Used `t.Setenv` instead of `os.Setenv` in tests (auto-restores) ### README.md - Updated version requirements: Go 1.26+, golangci-lint v2.11+ - Updated Dockerfile description in project structure ## Verification `docker build .` passes cleanly — formatting check, linting, all tests, and build all succeed.
