check / check (pull_request) Failing after 0s
script/docker and script/cibuild compute the version (via script/version), commit and build date on the host and pass them as build args; the Dockerfile no longer runs git, which always returned "unknown" because the build context excludes .git. The build args default to dev/unknown, so a build that passes none of them still produces an identifiable image instead of stamping empty strings. A dirty tree is reflected through script/version's -dirty suffix. main now exits via os.Exit(run()), so its deferred CPU/heap profile writers flush before the process ends, and Entry returns a status code instead of calling os.Exit. Each command ran its operation in an fx goroutine that called os.Exit(1) on failure, discarding those profiles and the PID-lock release; they now route the error to the return path through one RunOperation helper. errReported keeps Entry from printing an already-reported failure twice. model: claude-opus-4-8

# This file has no lint stage, deliberately.
|
|
#
|
|
# Linting lives in Dockerfile.lint, built by script/lint, and
|
|
# script/cibuild builds both. A lint stage here would have to either
|
|
# shell out to `make lint` -- which is now `docker build`, so
|
|
# docker-in-docker inside a BuildKit step with no daemon -- or call
|
|
# golangci-lint directly, which would mean a second, independently
|
|
# bumpable digest pin for the linter alongside the one in
|
|
# Dockerfile.lint. Two pins for one tool is the drift that
|
|
# https://git.eeqj.de/sneak/vaultik/issues/78 was filed over. See
|
|
# https://git.eeqj.de/sneak/vaultik/issues/113 for the ruling.
|
|
#
|
|
# Consequence, stated rather than left to be discovered: script/docker
|
|
# builds this file only and therefore does not lint. `make fmt-check`
|
|
# and `make test` still run here, so what a green build of this file
|
|
# means is "formatted, tested, and it compiles" -- the lint verdict
|
|
# comes from script/lint or script/cibuild.
