actions/checkout can't run in the build job: the Gitea runner executes JS actions via `docker exec node …` inside the job container, and gentoo/stage3 ships no node, so checkout died with `exec: "node": ... not found` (exit 127) in run 111. Revert the build job to the node-free curl+tar checkout (restore net-misc/curl, /var/db/repos/azy5030 paths) and document why. The lint job keeps actions/checkout — it has no container: and runs in the runner's default node-capable image, where plain checkout works on this SHA-1 repo (confirmed green in run 111's lint job).

# CLAUDE.md
|
|
|
|
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
|
|
|
## What this is
|
|
|
|
A personal **Gentoo ebuild repository (overlay)**, repo name `azy5030`, EAPI 8,
|
|
`masters = gentoo`, thin + unsigned Manifests (`metadata/layout.conf`). It packages
|
|
software not in the main `::gentoo` tree. Currently one package:
|
|
`dev-util/gitea-runner`. Hosted on a self-hosted Gitea at `git.azy.dev`. (This repo
|
|
is a standard SHA-1 repo; the sibling `homeserver` repo is SHA-256, so workflow
|
|
snippets copied from it may carry a `GIT_DEFAULT_HASH: sha256` checkout override
|
|
that this repo must *not* use.)
|
|
|
|
## The vendored-build model (the core design)
|
|
|
|
`dev-util/gitea-runner` is a `go-module` ebuild built **offline** from upstream
|
|
`gitea/runner` source. Gentoo's build sandbox has no network, so Go modules cannot be
|
|
fetched at build time. Instead they are vendored ahead of time:
|
|
|
|
1. The upstream source archive is `SRC_URI`'d from gitea.com's `/api/v1/.../archive`
|
|
endpoint (a plain `git clone`/`go get` is never used).
|
|
2. A **vendor tarball** (`${P}-vendor.tar.xz`, the result of `go mod vendor`, packed
|
|
deterministically) is uploaded as a **release asset on this repo** and is the second
|
|
`SRC_URI`. `S="${WORKDIR}/runner"`.
|
|
3. `dev-util/gitea-runner/Manifest` pins BLAKE2B/SHA512 of both tarballs. `emerge`
|
|
verifies against the Manifest, then compiles offline from `vendor/`.
|
|
|
|
Consequences when editing the ebuild:
|
|
|
|
- `LICENSE` must cover **every vendored module's** license, not just upstream's MIT.
|
|
The bump PR checklist suggests `go-licenses report ./...` to confirm.
|
|
- `BDEPEND` Go version tracks upstream's `go.mod` `go` directive.
|
|
- The version string is injected via ldflags into
|
|
`gitea.com/gitea/runner/internal/pkg/ver.version`; CI asserts `gitea-runner --version`
|
|
echoes `v${PV}`. If upstream moves that symbol path, the build "succeeds" but reports
|
|
the wrong version.
|
|
|
|
## Bumping to a new upstream version
|
|
|
|
This is **automated** by `scripts/bump-version.sh` (run daily by `bump.yaml`, or
|
|
`workflow_dispatch`). To do it manually you must reproduce its steps, because a version
|
|
bump is never just renaming the ebuild — the vendor tarball must be regenerated and
|
|
re-uploaded as a release asset, or the build will fail Manifest verification. The script:
|
|
|
|
1. Reads the latest `vX.Y.Z` from upstream `releases.rss`; compares to the newest
|
|
committed ebuild. Exits early if up to date or if a `bump/gitea-runner-<ver>` branch
|
|
already exists.
|
|
2. Downloads the source archive, runs `go mod vendor`, packs a reproducible
|
|
`*-vendor.tar.xz` (`--sort=name --mtime='UTC 1970-01-01' --owner=0 --group=0`).
|
|
3. Creates/reuses a release tagged `${PN}-${ver}-vendor` and uploads the tarball asset.
|
|
4. `git mv`s the ebuild to the new version, rewrites `BDEPEND`'s Go version from
|
|
upstream `go.mod`, and regenerates the Manifest with `pkgdev manifest` (after copying
|
|
both distfiles into `/var/cache/distfiles` and wiring a temporary `repos.conf`).
|
|
5. Validates: `pkgcheck scan`, then `emerge` + `gitea-runner --version | grep v${ver}`.
|
|
6. Commits, pushes the branch, opens a PR against `master`.
|
|
|
|
Requires a `BUMP_TOKEN` repo secret (scopes: repository read/write, write release) plus
|
|
a Gentoo env with `go pkgdev git curl xz jq`.
|
|
|
|
## CI (`.gitea/workflows/ci.yaml`)
|
|
|
|
Runs on every push, two jobs. A **`lint`** job runs on the plain Docker-backend runner
|
|
(no container), checks out with `actions/checkout`, installs the linters, and runs
|
|
`just lint` (markdownlint/shellcheck/yamllint/actionlint). The **`build`** job has
|
|
`needs: lint` (lint is a gate) and runs inside a `gentoo/stage3:amd64-openrc` container:
|
|
`emerge-webrsync` to sync `::gentoo` → configure portage (disables binpkg signature
|
|
verification so prebuilt deps like `dev-lang/go` are pulled, not compiled) → **check out
|
|
via `curl + tar`, not `actions/checkout`** into `/var/db/repos/azy5030` → `pkgcheck scan`
|
|
→ `emerge` → assert `gitea-runner --version` matches the ebuild version.
|
|
|
|
The build job can't use `actions/checkout` (even though the lint job does): the Gitea
|
|
runner executes JS actions by `docker exec node …` *inside* the job container, and
|
|
`gentoo/stage3` ships no node, so any JS action fails with exit 127. The lint job has no
|
|
`container:`, so it runs in the runner's default node-capable image and checkout works.
|
|
|
|
## Conventions / gotchas
|
|
|
|
- **YAML** is linted by `.yamllint.yaml` (relaxed: line-length and document-start
|
|
disabled; `truthy.check-keys: false` so `on:` is allowed unquoted).
|
|
- `metadata/md5-cache/` is **gitignored** — portage regenerates it on sync, so never
|
|
commit it (a stale `gitea-runner-1.0.4` file may linger on disk untracked).
|
|
- The bump script and CI deliberately preserve the scheme of `GITHUB_SERVER_URL`: on the
|
|
self-hosted runner it is an internal `http://` endpoint. Don't hardcode `https`.
|
|
- New packages must be added to `profiles/categories` (currently just `dev-util`).
