Adds built-in actions, native Go actions shipped with the runner and selected with `uses: builtin:<name>`. Jobs need no action download and no Node in their image. The first one is `builtin:checkout`, a subset of `actions/checkout` with `repository`, `ref`, `token`, `path` and `fetch-depth`. Other inputs fail the step. The runner clones shallowly on its host and copies the tree into the job, while `gitea-runner exec` copies the local working directory for the workflow's own ref. `actions/checkout` and other remote actions are unchanged. A clone ref of `HEAD` now shallow-clones the remote's default branch, which checkout uses for other repositories. --------- Co-authored-by: silverwind <[email protected]> Co-authored-by: silverwind <[email protected]> Reviewed-on: https://gitea.com/gitea/runner/pulls/871 Reviewed-by: silverwind <[email protected]> Co-authored-by: bircni <[email protected]>

## Job log line format
|
|
|
|
Gitea stores one log row per line and its web UI decodes the payload, so getting the encoding
|
|
wrong never fails a test here, it only shows up in the browser.
|
|
|
|
**A row cannot contain a real newline.** `FormatLog` rewrites `\n` to a literal backslash-n and
|
|
truncates at 64 KiB on a byte boundary.
|
|
|
|
**The payload of a line starting with a recognised prefix is decoded**, with the escape set
|
|
depending on the prefix:
|
|
|
|
| prefix | decodes |
|
|
| --- | --- |
|
|
| `##[error]` `##[warning]` `##[notice]` `##[debug]` `##[group]` `##[endgroup]` `##[add-matcher]` | `%25` `%0D` `%0A` `%3B` `%5D` |
|
|
| `::error::` `::warning::` `::notice::` `::debug::` (with or without ` key=value` properties), `::group::` `::endgroup::` `::add-matcher::` | `%25` `%0D` `%0A` |
|
|
| `##[command]` `[command]`, or no recognised prefix | nothing |
|
|
|
|
### Rules
|
|
|
|
- **Emitting a command line?** Escape the payload with `runner.EscapeCommandData`. One escaper
|
|
covers both forms: it escapes `%` first, so a literal `%3B` becomes `%253B` that the extra
|
|
`##[…]` rules cannot match, and a raw `;` or `]` is never decoded. It is also what makes
|
|
multi-line work, `\n` becomes `%0A` and the UI turns it back into a line break.
|
|
- **Forwarding a command from step output?** Leave the payload alone, it arrived escaped and is
|
|
decoded once. Decoding here double-decodes and destroys multi-line.
|
|
- **No prefix?** Do not escape, and split multi-line values into one row each.
|
|
- **Interpolating a secret?** Masking runs after escaping, so `AppendSecretMasker` registers the
|
|
encoded forms too.
|
|
- Command *properties* also escape `%3A` and `%2C`, which the UI never decodes, so the reporter
|
|
decodes exactly those two when folding a location into an annotation.
|
|
|
|
## Built-in actions
|
|
|
|
Each lives in `internal/pkg/action/<name>` and is registered in `builtinActions` in
|
|
`act/runner/step_action_builtin.go`.
|
|
|
|
## End-to-end compatibility tests
|
|
|
|
`make test-e2e` runs the runner against `E2E_GITEA_IMAGE`. It defaults to the nightly image.
|
|
It requires Docker and is excluded from `make test`. CI runs stable and nightly variants in
|
|
parallel.
|
|
|
|
The suite shares one Gitea and regular runner. Cache and ephemeral scenarios use isolated
|
|
repository runners. A run path is `<workflow>@<ref>` and a log row is `<timestamp>Z <payload>`.
