# Built by builds.sr.ht (.build.yml) and published to our own apk repo at
# repo.bigb.es/alpine/v3.22/bigbes. The srht deployment installs it from there
# instead of cloning and compiling this repo inside its Dockerfile.
#
# pkgver is READ FROM THE ENVIRONMENT, not rewritten in place. CI's `version`
# task exports PKGVER from one `git describe`: a tag becomes `0.2.0`, a tag plus
# commits becomes `0.2.0_git7` (which sorts AFTER the release in Alpine's
# comparison), and a repository with no tags at all falls back to
# `0.0.<commit count>`. The literal below is what a local `abuild` that was
# handed no PKGVER honestly builds.
#
# The earlier arrangement had CI `sed` that literal here before abuild ran, and
# it cannot stand: Go records vcs.modified in every binary compiled inside a
# repository and reads that flag from `git status --porcelain`, so a CI task
# that rewrites a tracked file in the checkout stamps every packaged binary
# dirty for the life of the apk. Measured on go1.26.5.

# !check      — the suites are run by the `test` task of .build.yml, against the
#               Postgres that manifest brings up, and they run BEFORE this
#               package is built. Letting abuild run them again would repeat the
#               work with SPECSRHT_TEST_PG unset, i.e. with every database suite
#               skipping — 67 tests of db/, service/ and cmd/specsrht-migrate/,
#               measured. That task's DSN guard is what makes this line true; a
#               pipeline without it packages code nothing tested.
# !tracedeps  — CGO_ENABLED=0, so the binaries are static

	# naming it, so a package() reached without a build() says so.
