Re-vendor the canonical files from sneak/prompts at dd4027b (closes #65)
check / check (push) Successful in 5m33s
Details

Browse Source 
The vendored files are fetched from sneak/prompts commit dd4027b. This
repository's own entries come after the canonical content, at the end of
each file: /bin in .dockerignore, the Go lines of .gitignore and [*.go]
in .editorconfig; the test-support deny list has no entries of its own.
The lint phase moves to golangci-lint v2.14.0. The build stage now takes
the version from git describe on the .git the build context carries,
unless VERSION is passed, and fails when .git is present but no version
comes out. The test phase drops -count=1, which the policy says it does
not need, and keeps its tmpfs build cache. One test calls Header.Get
with X-Real-IP, as canonicalheader asks.

(e.g. a web frontend compiled in a separate stage), the lint phase must
create placeholder files so the embed directives resolve. Example:
`RUN mkdir -p web/dist && touch web/dist/index.html web/dist/style.css`.
- If the project requires CGO or system libraries for linting (e.g.
`vips-dev`), install them in the lint phase with `apk add`.
- `ARG VERSION=dev` is declared in the stage that compiles and supplied by
`script/docker` and `script/cibuild`; no stage may call `git describe`.
- If the project requires CGO or system libraries for linting, install them
in the lint phase. The `golangci/golangci-lint` image is Debian-based and
has no `apk`, so install with `apt-get` under the Debian package name
(`libvips-dev`, where alpine says `vips-dev`), and delete the package
lists in the same `RUN`, so the layer does not keep them:
```dockerfile
RUN apt-get update \
&& apt-get install -y --no-install-recommends libvips-dev \
&& rm -rf /var/lib/apt/lists/*
```
- `.dockerignore` lets `.git` into the build context. It keeps out every git
`config` at any depth (`**/.git/config`, `**/.git/modules/**/config`): the
repository's own, each submodule's under `.git/modules/`, and that of a
submodule keeping its own `.git` directory. `git describe` does not need
them, and each can hold a credential: a password in a remote URL, or the
token the CI checkout step stores there. A submodule whose name has a
`config` segment (`config`, `deploy/config`, `config/lib`) loses its whole
git directory to `**/.git/modules/**/config`, and Go's version stamping
then fails the build: give it a name without that segment
(`git submodule add --name`). The stage that compiles has `git` (the
Debian Go image has it; an alpine one needs `apk add --no-cache git`) and
takes the version from the `VERSION` build argument when one is given,
otherwise from `git describe --tags --always`. That gives the tag on a
tagged commit; on a later commit, the tag, the number of commits since it
and the short commit (`v1.2.3-4-gabc1234`); and the short commit when no
tag is reachable. The stage that compiles also marks its working directory
safe for git (`git config --system --add safe.directory /src`): a context
sent as a tar stream keeps the sender's file owners, and git refuses a
checkout owned by another user, so the version would come out empty.
`ARG VERSION` has no default, and the build fails if the context carries
`.git` and the version still comes out empty, `dev` or `unknown`. A plain
`docker build .` with no build arguments must succeed; a Dockerfile that
refuses an empty build argument drops that refusal and keeps the argument.

Note that this is a second, independent cache, stacked below the Docker
layer cache that [issue #26](https://git.eeqj.de/sneak/prompts/issues/26)
addresses. `CHECK_EPOCH` guarantees the `RUN make test` _step_ re-executes;
it does not guarantee `go test` inside that step does any work, because the
`GOCACHE` baked into earlier image layers survives into the re-executed
step. They are two separate defects requiring two separate fixes, and a fix
for one must not be recorded as covering the other.
That cache is Go's own, separate from Docker's layer cache. Go stores a
passing result in its cache directory (`GOCACHE`), and when the same tests
run again on unchanged code it prints that result, marked `(cached)`,
without running them. That matters on a developer's machine, where this
target runs and the directory lasts from one run to the next. The `test`
phase of the `Dockerfile` needs no `-count=1`: its base image holds no
result for this repo's tests and nothing before its `go test` step runs a
test, so there is nothing to replay. `--no-cache` (above) is what makes that
step run on an unchanged tree.
