check / check (push) Successful in 3m29s
The Dockerfile lint and build stages and Dockerfile.lint each carried their own apk add list, a copy of what script/bootstrap installs. They now copy script/, go.mod and go.sum and run script/bootstrap, so that layer is reused until one of those changes. script/bootstrap gains a C compiler check: the golang image has none, and cgo needs one. The build adds -trimpath and -s -w; CGO_ENABLED=1 stays, as govips links libvips. ARG VERSION moves to just above the build, so a new version reruns neither script/bootstrap nor the tests. Model: opus-5-5

# script/bootstrap: install all dependencies needed to build and develop
|
|
# this repo. Idempotent: every install is guarded by a check so already
|
|
# installed tools are skipped. Base tooling comes from nix, apt, brew,
|
|
# or apk (detected in that order); assumes NOTHING is present (not git,
|
|
# make, or go). The linter is never installed on the host: golangci-lint
|
|
# runs only inside a container, Dockerfile.lint or the Dockerfile lint
|
|
# stage (see script/lint). A C compiler and the CGO image libraries
|
|
# (pkg-config, vips, libheif) are installed for the govips bindings.
|
|
# Both Dockerfiles run this script too, so their build dependencies are
|
|
# the ones listed here.
