build: re-vendor canonical files from prompts dd4027b (closes #257)
check / check (push) Successful in 4m6s
check / check (push) Successful in 4m6s
The canonical files are fetched whole from sneak/prompts at dd4027b. Kept after the canonical content: the livednstest deny entry in .golangci.yml, /bin in .dockerignore, this repo's own .gitignore lines and a [*.go] tab section in .editorconfig. The workflow keeps its concurrency block and persist-credentials: false. Lint and test are phases of the Dockerfile (golangci-lint v2.14.0; tests on the Debian Go 1.25.7 image as an ordinary user, with the same flags); the build stage depends on both and stamps the version the canonical way. Dockerfile.lint is gone; the prettier stages of Dockerfile.fmt moved into the Dockerfile. Every scripted docker build passes --no-cache; script/cibuild bootstraps, runs script/check, then builds the image. script/fmt-check absorbs fmt-check-go and fmt-check-markdown. Model: opus-5-5

- Every repo should have a `Dockerfile`. All Dockerfiles must run `make check`

as a build step so the build fails if the branch is not green. For non-server
|

repos, the Dockerfile should bring up a development environment and run

prerequisites by running `script/bootstrap` rather than duplicating installs
|

inline; COPY `script/` and the dependency manifests (`package.json` +
|

`yarn.lock`, `go.mod` + `go.sum`, etc.) before running it so the bootstrap
|

layer stays cached until dependencies change.
|
||||
- Every repo should have a `Dockerfile`, and it carries the repo's gates: a
|
||||
`lint` phase and a `test` phase, with the final stage depending on both so the
|
||||
image cannot be built unless they pass. For non-server repos the final stage
|
||||
brings up a development environment; for server repos it is the runtime image.
|
||||
The gate phases and the build stage start from their pinned base images and
|
||||
install what those images lack either inline, as the canonical Go `Dockerfile`
|
||||
below does for `git`, or by running `script/bootstrap`, as the `prompts`
|
||||
repo's own `Dockerfile` does for its yarn packages. The development
|
||||
environment stage installs development prerequisites by running
|
||||
`script/bootstrap` rather than duplicating its installs inline. A stage that
|
||||
runs `script/bootstrap` COPYs `script/` and the dependency manifests
|
||||
(`package.json` + `yarn.lock`, `go.mod` + `go.sum`, etc.) before running it.
|
||||
|
||||
- **Dockerfiles must use a separate lint stage for fail-fast feedback.** Go
|
||||
repos use a multistage build where linting runs in an independent stage based
|
||||
on the `golangci/golangci-lint` image (pinned by hash). This stage runs
|
||||
`make fmt-check` and `make lint` before the full build begins. The build stage
|
||||
then declares an explicit dependency on the lint stage via
|
||||
`COPY --from=lint /src/go.sum /dev/null`, which forces BuildKit to complete
|
||||
linting before proceeding to compilation and tests. This ensures lint failures
|
||||
surface in seconds rather than minutes, without blocking on dependency
|
||||
download or compilation in the build stage.
|
||||
- **Linting and testing run in Docker, as phases of the `Dockerfile`.** There is
|
||||
no separate lint file. `script/lint` and `script/test` each build one phase
|
||||
and nothing else:
|
||||
|
||||
The standard pattern for a Go repo Dockerfile is:
|
||||
```sh
|
||||
docker build --no-cache --target lint -t "$(script/projectname)-lint" .
|
||||
docker build --no-cache --target test -t "$(script/projectname)-test" .
|
||||
```
|
||||
|
||||
**A stage that is not the last one in the file is built only when the final
|
||||
stage's chain depends on it, or when `--target` names it.** That is why the
|
||||
two gates are always invoked by name here, and why the final stage carries a
|
||||
`COPY --from=` of a harmless file from each of them: without that edge a
|
||||
plain `docker build .` builds the last stage alone and exits 0 having linted
|
||||
and tested nothing.
|
||||
|
||||
**Every `docker build` in `script/` is tagged**, here and in
|
||||
`script/cibuild` and `script/docker`. An untagged build leaves a dangling
|
||||
image behind on every invocation, on every developer host and every CI
|
||||
runner; a tagged one replaces the previous image.
|
||||
|
||||
Inside a phase the tool is invoked directly — `golangci-lint`, `go test`,
|
||||
`eslint`, `prettier` — never through `make lint` or `script/test`, which are
|
||||
themselves a `docker build` and would recurse into a daemon that does not
|
||||
exist in a build step. Formatting is the exception and stays on the host:
|
||||
`script/fmt` writes the working tree, and `script/fmt-check` is its
|
||||
read-only twin.
|
||||
|
||||
**No lint verdict may come from a host invocation of the linter.** On a
|
||||
shared host golangci-lint reads a result cache keyed on file content rather
|
||||
than location, so a second checkout of the same content is served the first
|
||||
one's findings, and a host-global lock in `$TMPDIR` makes concurrent runs
|
||||
exit non-zero with `parallel golangci-lint is running` — a status a caller
|
||||
cannot tell from real findings. Both have produced wrong verdicts in this
|
||||
org, in both directions. A container has its own cache, its own `TMPDIR` and
|
||||
a digest-pinned binary, so neither is reachable.
|
||||
|
||||
- **Any build that runs checks is built with `--no-cache`.** Docker invalidates
|
||||
a `COPY` layer only when the copied content changes, so on an unchanged tree
|
||||
the check `RUN` is served from cache, nothing executes, and the build still
|
||||
exits 0. Every `docker build` in `script/` therefore passes `--no-cache`:
|
||||
`script/lint`, `script/test`, `script/cibuild` and `script/docker` are the
|
||||
four, and there is no fifth — `script/check` runs the two gate phases and
|
||||
`script/fmt-check`, and builds no image of its own. A bare `docker build .` is
|
||||
not evidence that anything ran: a sub-second build reporting success is a
|
||||
cache hit, not a result. Never invalidate by pruning — `docker builder prune`
|
||||
and friends destroy a build cache shared with every other build on the host.
|
||||
When a check is added or changed, prove it works by planting a defect it must
|
||||
catch and watching the run fail on it, then revert the defect. A green run
|
||||
alone shows neither that the check ran nor that it covers what it should.
|
||||
|
||||
- **The gate phases are separate stages, and the build stage depends on both.**
|
||||
The lint phase is based on the `golangci/golangci-lint` image (pinned by
|
||||
hash), so lint failures surface in seconds rather than after a full compile,
|
||||
and the test phase is based on the Debian Go image. The canonical Go repo

Key points:
|
||||
- The lint stage uses the `golangci/golangci-lint` image directly (it
|
||||
includes both Go and the linter), so there is no need to install the
|
||||
linter separately.
|
||||
- `COPY --from=lint /src/go.sum /dev/null` is a no-op file copy that creates
|
||||
a stage dependency. BuildKit runs stages in parallel by default; without
|
||||
this line, the build stage would not wait for lint to finish and a lint
|
||||
failure might not fail the overall build.
|
||||
- The lint phase uses the `golangci/golangci-lint` image directly (it has
|
||||
both Go and the linter), so nothing needs installing.
|
||||
- `COPY --from=<phase> /src/go.sum /dev/null` is a no-op copy whose only
|
||||
purpose is the ordering edge. BuildKit runs stages in parallel by default,
|
||||
and a stage nothing depends on is not built at all, so without these two
|
||||
lines a red gate would not fail the build.
|
||||
- Keep the runtime stage last, and if you add a stage after it, give it the
|
||||
same two copies. A plain `docker build .` builds the last stage's chain
|
||||
and nothing else.
|
||||
- If the project uses `//go:embed` directives that reference build artifacts
|
||||
(e.g. a web frontend compiled in a separate stage), the lint stage must
|
||||
(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`.
|
||||
The lint stage should not depend on the actual build output — it exists to
|
||||
fail fast.
|
||||
- If the project requires CGO or system libraries for linting (e.g.
|
||||
`vips-dev`), install them in the lint stage with `apk add`.
|
||||
- The build stage runs `make test` after compilation setup. Tests run in the
|
||||
build stage, not the lint stage, because they may require compiled
|
||||
artifacts or heavier dependencies.
|
||||
- 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.
|
||||
|
||||
- Every repo should have a Gitea Actions workflow (`.gitea/workflows/`) that
|
||||
runs `script/cibuild` (which runs `docker build .`) on push. Since the
|
||||
Dockerfile already runs `make check`, a successful build implies all checks
|
||||
pass.
|
||||
runs `script/cibuild` on push, and checks out the repo as its only other step.
|
||||
That script bootstraps, runs the gate phases, and then builds the image, so a
|
||||
successful run means every check passed; a bare `docker build .` does not
|
||||
carry the same guarantee, because its gate phases may come from the cache. The
|
||||
image build is uncached and so runs the gate phases a second time. That is the
|
||||
price of the rule above, and it is worth paying: the image that ships is built
|
||||
from a run of its own gates rather than from a cache entry. A separate
|
||||
workflow limited to `main` by a `branches` list under `on: push` cannot be
|
||||
checked by review: to try a change to it, add the feature branch to that list
|
||||
and push, then remove the branch from the list again before merging. Keep any
|
||||
job in it that publishes behind `if: github.ref_name == 'main'`, so the run
|
||||
from the feature branch publishes nothing.

|
||||
from `https://git.eeqj.de/sneak/prompts/raw/branch/main/.gitignore` when
|
||||
setting up a new repo. These patterns are written to `.gitignore`'s own
|
||||
semantics, in which an unanchored pattern already matches at every depth; they
|
||||
are not a `.dockerignore` and must not be transplanted into one unmodified.
|
||||
|
||||
- **`.dockerignore` does not use `.gitignore` semantics, and copying patterns
|
||||
across unmodified leaves secrets in the build context.** Docker matches with
|
||||
`moby/patternmatcher`: `filepath.Match` semantics plus a `**` extension, so
|
||||
`*` does not cross `/` and a pattern without a leading `**/` is anchored at
|
||||
the build-context root. A `.dockerignore` listing `.env`, `*.pem` and `*.key`
|
||||
therefore excludes only the copies at the repository root, while `config/.env`
|
||||
and `certs/server.key` still reach the context and can land in an image layer
|
||||
— which is more dangerous than a short file with no secret patterns at all,
|
||||
because it reads as solved and stops anyone looking. Give every
|
||||
depth-independent pattern the `**/` prefix and leave only genuinely
|
||||
root-anchored entries unprefixed: `.claude`, and the repo's own host-built
|
||||
binary, written `/myapp` and never `**/myapp`, which would also match
|
||||
`cmd/myapp/` and delete the package directory from the context. Matching is
|
||||
case-sensitive, and an ALL-CAPS twin per pattern still misses `Server.Key`, so
|
||||
secret names use character ranges — `**/*.[kK][eE][yY]`, `**/*.[pP][eE][mM]`,
|
||||
and likewise for `.envrc` and the extensionless SSH keys. Where such a pattern
|
||||
also catches something the build needs, re-include it with a negation
|
||||
(`!docs/example.env`); deleting the pattern reopens the exposure for every
|
||||
other file it covers. Fetch the standard `.dockerignore` from
|
||||
`https://git.eeqj.de/sneak/prompts/raw/branch/main/.dockerignore` and extend
|
||||
it with the repo's own artifacts.
|
||||
|
||||
- **In-repo agent scratch belongs in both files, written to each file's own
|
||||
semantics.** `.claude/` holds one worktree per in-flight agent — an entire
|
||||
additional checkout of the repo — so under `COPY . .` the build context
|
||||
inflates by a multiple of the repo and another session's unreviewed work can
|
||||
be copied into an image layer. In `.gitignore` the entry is `.claude/`,
|
||||
unanchored. In `.dockerignore` it is `.claude`, anchored and with **no** `**/`
|
||||
prefix, because the prefixed form would also delete any nested directory of
|
||||
that name from the build. Anchoring carries a known gap that the canonical
|
||||
`.dockerignore` states in its own comment, since consuming repos receive the
|
||||
file and not the tracker: the directory is created in the agent's working
|
||||
directory, so a repo running agents in subdirectories still ships
|
||||
`services/api/.claude/` and must add its own anchored entry there.
|
||||
|
||||
- **A plain `docker build .` of a clone stamps the version that
|
||||
`git describe --tags --always` gives**, derived from the `.git` in the build
|
||||
context as the canonical `Dockerfile` above shows. Without its failure check,
|
||||
a missing `git` or an unreadable checkout would leave `-X main.Version=` empty
|
||||
and the build would still exit 0. `script/docker` and `script/cibuild` pass
|
||||
the version they compute on the host; it takes precedence. They do this
|
||||
byte-identically across repos:
|
||||
|
||||
```sh
|
||||
# Own line: a failing command substitution inside an argument does not
|
||||
# trip `set -e`, so the inline form degrades to an empty constant.
|
||||
version="$(git describe --tags --always --dirty 2>/dev/null || true)"
|
||||
[ -n "$version" ] || version="unknown"
|
||||
docker build --no-cache \
|
||||
--build-arg VERSION="$version" \
|
||||
-t "$(script/projectname)" .
|
||||
```
|
||||
|
||||
`--always` makes an untagged repo yield an abbreviated commit hash rather
|
||||
than failing, and the `[ -n "$version" ]` line is the single place the
|
||||
fallback is applied — a live check that fires on a build from an export with
|
||||
no `.git` and on a repository with no commits yet. Do not fold it into the
|
||||
substitution as `|| echo unknown`, which makes the guard unreachable. The
|
||||
Dockerfile's side is `ARG VERSION` in the stage that compiles, declared
|
||||
there because `ARG` is stage-scoped; passing `VERSION` to a repo whose
|
||||
Dockerfile declares no such `ARG` is ignored and costs nothing, which is why
|
||||
the scripts stay byte-identical. One consequence for CI: the standard
|
||||
checkout action clones shallow and fetches no tags, so a repo that embeds a
|
||||
tag-derived version must set `fetch-depth: 0` on its checkout step.
|
||||
|
||||
- **Verify `.dockerignore` by enumerating the image, not by reading the
|
||||
patterns.** Plant files at the root _and_ at least two directories deep, build
|
||||
a probe image that does `COPY . .`, and list what actually landed
|
||||
(`docker run --rm --entrypoint find IMAGE /app`). The `transferring context`
|
||||
size is not a substitute: a nested secret is a few bytes, and BuildKit
|
||||
transfers only the delta from the previous build.

`go 1.27.1` but not `go 1.28`. That digest is the only pin, since no repo

installs golangci-lint on the host. A repo sets the lint phase digest to the

one named here and re-vendors `.golangci.yml` in the same commit, whichever of

`PATH` only, so on an already-provisioned machine the pin is inert and a
|
||||
version bump is a silent no-op — while the Dockerfile, installing into a clean
|
||||
image, gets the pinned version, so a local `make check` and `make docker` can
|
||||
disagree about what the tool even is. The canonical form:
|
||||
- compares the installed version against the pin over the **whole** version
|
||||
token; a parser that stops at the first `-` reports `2.12.2` for a host
|
||||
running `2.12.2-rc1` and skips the install;

||||
- treats absent, non-zero, empty or unrecognised `--version` output as a

mismatch, so the failure direction is a redundant install and never a
|
||||
skipped one;

||||
- after installing, re-resolves the binary the way callers do — `hash -r`,
|
||||
then through `PATH`, not through the directory the installer wrote to —

and fails naming the resolved path, since an install that a shadowing

binary hides succeeds while changing nothing any caller sees;
