silverwind 20c8b4abc4 refactor: replace go-git with the git CLI for gitignore filtering (#1309)
Replace go-git in `exec --use-gitignore` filtering with `git ls-files`. The git CLI is already required for action clones since https://gitea.com/gitea/runner/pulls/1277, so this drops `go-git` and 14 other modules, and filtering now follows git's own ignore rules.

Also stop deleting a remote action's `.gitignore` before copying it. Tracked files are never filtered, so the deletion only made copied actions differ from GitHub's action tarballs.

Lunny Xiaoandbircni e0ef637805 refactor(logging): replace the logrus backend with log/slog (#1304)
Log through `log/slog`, with a console `slog.Handler` that writes the text the runner has always written (sorted `key=value` fields on a plain stream, a colored prefix on a terminal), so nothing changes for users. I compared its output byte for byte with logrus's `TextFormatter` over plain, colored, timestamped and caller cases.

Why not `slog.TextHandler`: its output differs from what users and their log parsers see today, and `ReplaceAttr` cannot close the gap.
- level is `WARN` where logrus wrote `warning`, and time has milliseconds and no quotes
- fields keep call order instead of being sorted
- the caller is one `source=` key, where the runner writes `func=` and `file=` (reshaped by `callPrettyfier`), and `ReplaceAttr` returns a single attribute
- no colored prefix on a terminal
- no hook to rewrite a whole formatted line, which the process-wide secret masking relies on

Libraries that log through logrus's global logger (the workflow model, the Docker client) are forwarded to the process-wide logger, so they keep following its level, format and secret masking. This is why logrus stays in `go.mod`.

Lunny Xiaoandbircni de961b91eb refactor(logging): add a logging abstraction and move the job logger onto it (#1295)
Add `act/common/logging`: a printf-style `Logger` on a slog-shaped `Handler`, with a logrus-backed handler as the only backend, plus a `logtest` handler for tests. Move the job logger onto it: `common.Logger` returns `*logging.Logger`, the job log formatters and the `Reporter` hook become handlers, and composite step IDs travel in the context.

Logging is tightly coupled to logrus types (hooks, formatters, `Entry.Data`). Going through our own interface first lets the remaining call sites move over with unchanged behavior, and lets the backend be swapped for `log/slog` in one place afterwards. The global process logger and its masking formatter stay on logrus for now.

silverwind ad9eeb668a fix: job container, daemon startup, action cache and exec fixes (#1294)
- Keep `GITHUB_ENV`, `GITHUB_OUTPUT`, `GITHUB_STATE` and `GITHUB_PATH` when a job times out or is cancelled, so post steps still get their state
- Retry the startup Declare while Gitea is unreachable instead of exiting, still failing fast on rejected registrations, auth and misconfiguration
- Reuse a local image when a platform variant such as `linux/arm/v7` is requested instead of pulling again
- Read `PATH` from the created job container so cross-architecture jobs get tool paths for the right architecture
- Extract action copies relative to the act volume so they never cross an image's `/var/run` symlink, which rootless Podman rejects
- Keep the job container's entrypoint when container options set `--entrypoint`, warning instead of appending it to the keep-alive command
- Lock action cache entries across runner processes that share a cache directory
- `exec`: omit `GITHUB_SERVER_URL` and `GITHUB_API_URL` without `--gitea-instance` instead of exporting a bare `https://`, and read owner and repository from any origin remote

f963e9cfe8 enhance: support client certificates for mutual TLS (#1273)
Add `runner.client_cert_file` and `runner.client_key_file` for Gitea instances that require mutual TLS. The runner presents the certificate on its RPCs, job summary uploads, and the action, reusable workflow and `builtin:checkout` clones from the instance. The files are read on use, so renewed certificates apply without a restart. Job steps do not get them. An incomplete or mismatched pair fails startup.

Clones now decide the token, client certificate and `runner.insecure` with one host check, which also gives reusable workflow clones the TLS settings they lacked. `runner.insecure` still only covers the registered address.

Allow `valid_volumes` entries ending in `:ro` to permit only read-only mounts, so a workflow can no longer mount writable a host path the runner only shares read-only, like a certificate store. `**:ro` allows any volume read-only. An entry without `:ro` that matches too still allows writable mounts.

A named volume allowed only through `:ro` is mounted with `nocopy`, because Docker otherwise fills an empty volume from the image even when it is mounted read-only.

27e9b4de87 fix!: use the git CLI for action clones and make builtin:checkout match actions/checkout (#1277)
The runner now uses the `git` command line instead of go-git to download actions and reusable workflows. go-git had recurring bugs and does not support SHA-256 repositories, and full clones of actions are several times faster.

`builtin:checkout` now runs `git` where the job runs and behaves like `actions/checkout`:

1. A branch is checked out as a local branch tracking `origin`, tag and pull request runs keep their ref, and a triggering tag that moved fails the step.
1. Later steps can fetch and push with the persisted token or SSH key.
1. It supports the `ssh-*`, `lfs`, `submodules`, `sparse-checkout`, `filter`, `fetch-tags`, `clean`, `persist-credentials`, `show-progress` and `set-safe-directory` inputs and the `ref` and `commit` outputs.
1. SHA-256 repositories work for actions, reusable workflows and `builtin:checkout`.

Git keeps the token off its command line, ignores `GIT_DIR` and similar variables inherited by the runner, and keeps action files LF regardless of `core.autocrlf`. A cancelled job lets git remove its lock files.

This is a breaking change: the runner needs Git 2.34.1 or newer on its `PATH`, and so do job images that use `builtin:checkout`. The official runner images include it.

Fail the workflow before any of its jobs run when a regular job omits `runs-on` or leaves it empty, as GitHub does, instead of running the job in the fallback image. Gitea rejects such workflows itself since https://github.com/go-gitea/gitea/pull/39480. This covers released Gitea versions, which hand a job without labels to any runner, and `exec`. Reusable workflow jobs and the stepless placeholders the runner builds for a job's `needs` are exempt.

83b63250a3 fix: strip log-driver and OOM options when privileged is off (#1283)
When privileged mode is disabled, reset `--log-driver`, `--log-opt`, `--oom-score-adj` and `--oom-kill-disable` from workflow `container.options`. Log drivers run in the host daemon, so a workflow could make it connect to any address, and `--oom-score-adj -1000` exempts a job from the host OOM killer.

Breaking: on unprivileged runners, workflows can no longer set these options, e.g. `--log-driver none` or `--log-opt max-size=10m`. They are dropped with a warning and the job still runs. Runner-level `container.options` and privileged runners are unaffected.

0cedd98051 feat: add Kubernetes backend (#1260)
Adds a Kubernetes backend. A `name:kubernetes://image` label runs the job as one pod through the Kubernetes API, with services as containers of the same pod. Step env is exported by a script sent over exec stdin, keeping it out of the pod spec and process arguments, and service env goes into a per-job Secret. Docker actions and container options are rejected. See `docs/kubernetes.md`.

Operators shape job pods with `kubernetes.pod_template`, with per-label `pod_templates` merged in `runs-on` order and a `$services` entry for service containers. The idle cleanup removes pods and Secrets a runner left behind.

The client calls the Kubernetes API directly and runs step commands over `coder/websocket` (same dependency used in gitea) instead of pulling in the heavyweight `kubernetes/client-go`. Includes an e2e test against k3s.

Zettat123 990ebaa2ac fix: restore the caller's event and inputs in reusable workflow jobs (#1250)
Fixes https://github.com/go-gitea/gitea/issues/38705

Gitea side: https://github.com/go-gitea/gitea/pull/39452

Jobs of a called workflow currently see `gitea.event_name == "workflow_call"`, and their `gitea.event.inputs` is replaced by the caller's `with:`. On GitHub they keep the caller's event, and their `inputs` are the run's `workflow_dispatch` inputs overlaid with the caller's `with:`.

For compatibility with older runners, Gitea keeps sending that form and adds a `gitea_workflow_call` key with the original trigger event name and inputs of the run, and the `inputs` Gitea resolved for the job. When the key is present, the runner restores `gitea.event_name` and `gitea.event.inputs` from it, and uses the resolved `inputs` for the job's expressions and the setup log.

Without that key (older Gitea, or jobs outside called workflows), nothing changes.

silverwindandbircni ace8653105 feat!: serve the actions cache from the runner (#1229)
Make cache requests go through the runner and remove outbound traffic from the cache server. The runner forwards them to `cache.external_server` when one is set, and attaches itself to each job network so jobs can reach it.

Benefits:

1. Jobs need no http proxy rules for the cache server, which `@actions/http-client` mishandles for CIDR ranges in `no_proxy` (https://github.com/actions/toolkit/pull/2495).
2. Only runners reach a shared cache server, which needs no route to Gitea.
3. A runner container sharing the host Docker socket now caches, where jobs previously could not reach it.

Breaks:

1. Jobs that reach `external_server` but not their runner, such as a remote `DOCKER_HOST`. The built-in cache has always needed that reachability, so both modes now agree. Set `cache.host` and `cache.port` to an address those jobs reach.
2. Jobs on `container.network: bridge`, where Docker rejects the alias, so the runner cannot attach and their cache fails as it does today. Leave `container.network` empty, or name a user-defined network.

Breaking: a host pattern that relied on `*` matching nested paths needs `**`, e.g. `/data/**` instead of `/data/*`. Named volumes and the bare `**` are unaffected.

Each job becomes a trace with a span per step, so operators can see where CI time goes in their existing observability backend. Jobs receive only `TRACEPARENT`, so instrumented tools inside them join the trace without seeing the collector's credentials. Metrics stay on the Prometheus endpoint, which a collector can scrape.

7ad12038d1 feat(runner): add built-in actions framework with checkout (#871)
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.

silverwind 98816a605c fix: skip jobs whose if fails to evaluate, update actionslib (#1247)
Updates actionslib to https://gitea.com/gitea/actionslib/releases/tag/v1.2.1.

1. A job whose `if:` fails to evaluate, like `fromJSON` of an invalid job output, is skipped with the error in its log instead of failing, like on GitHub Actions.
1. Workflows the runner reads itself, like with `exec`, are rejected when an expression does not parse, like an unclosed `${{` or an unknown context, instead of failing later.
1. Task payloads from Gitea are read without that check, because they hold evaluated text that may contain `${{`.
1. `if: False`, `if: ~` and other boolean, null or number conditions work.

silverwind 3962d0d970 fix: composite pre/post conditions read the job status (#1242)
A composite action's child run context starts with empty step results, so a nested action's `post-if: success()` saw the composite's own result and still ran after the job had failed, which let `actions/cache` save caches from failed jobs.

The `job` context now always comes from the job's run context. Only `success()` and `failure()` in a composite's own main steps read the composite's result, matching GitHub Actions.

silverwind 5310d8119a fix: docker proxy probe for podman and containerized runners (#1231)
Podman creates a missing bind source instead of rejecting it, so the Docker proxy probe passed even when the daemon could not see the runner's files. Jobs of Podman runners in a container got an empty directory at `/var/run/docker.sock` (https://gitea.com/gitea/runner/issues/1193#issuecomment-1700501).

The probe now binds the directory and stats its marker through the created container. A runner in a container stats the marker through its own container, so it no longer creates probe containers, which cost up to 2s per job. `make test-dind TARGET=podman` runs the probe against Podman in CI.

silverwind 699a97fc8c enhance: bind-mount job paths through the docker proxy (#1226)
Containers a job starts through its Docker socket, for example `docker run -v "$PWD:/src"`, `./data:/data` in docker compose, or actions like dockerfile-roast, can now bind-mount the workspace and other paths the job sees, as on a host, without `bind_workdir`.

The per-job Docker proxy rewrites container and volume create requests. A bind source, or the device of a `local` volume with `o: bind`, that lies under one of the job container's mounts is pointed at that mount's path on the daemon, read from inspecting the job container. Paths that already name a daemon path, like `GITEA_DOCKER_WORKSPACE`, and paths outside the job's mounts pass through unchanged.

The proxy now also starts when the runner runs in a container given the host's Docker socket, by placing its socket in the runner's working directory, and in rootless dind, by granting the daemon socket's group through an ACL.

Mount the job workspace volume, or the `bind_workdir` directory, above `<owner>/<repo>` instead of at the repository, like GitHub's work directory.

With the repository as a mount point, pnpm 12 puts its store in `node_modules/.pnpm-store` (https://github.com/pnpm/pnpm/pull/13536), so a restored `setup-node` pnpm cache creates `node_modules` before install. Renames into `$RUNNER_WORKSPACE` fail with `EXDEV` and removing the workspace fails with `EBUSY`.

Verified against GitHub hosted and container jobs with cold and warm caches, on volume and `bind_workdir` runners, covering checkout, cache, artifacts, github-script, the node, pnpm, bun, python, uv, go, rust, java, gradle, dotnet, ruby and terraform setup actions, docker and Dockerfile actions, buildx, compose via `GITEA_DOCKER_WORKSPACE`, services, host mode, `container.volumes` on the workspace and `exec`.

e0ce6776c7 perf(cache): skip redundant store writes and scans on cache requests (#1222)
Every cache hit rewrote the entry's access time, costing a bolt write and fsync per restore. Completed entries accessed within the last minute are no longer rewritten, and the in-use and retention windows grow by that minute so nothing is evicted earlier. Same-second rewrites are skipped, reservations are inserted in one transaction, and prefix lookups use the repository index instead of scanning every entry.

The store is still opened per request. Keeping it open, as this commit first did, is faster under concurrency but stops a second process sharing the cache directory from starting its cache server.

The README caching section is condensed and corrected.

silverwindandbircni 498282caaa fix: IPv6 URLs, cache-server SIGTERM and atomic task admission (#1217)
Three independent fixes, one commit each.

1. Hosts and ports were interpolated directly when building URLs, so a literal IPv6 address produced an unbracketed authority, making `ACTIONS_CACHE_URL`, `ACTIONS_RUNTIME_URL` and the artifact server listener unusable. Hosts are expected bare, as documented for `cache.host`, so an address that already carries brackets is no longer accepted.
2. `cache-server` waited on its own `os.Interrupt` channel and ignored SIGTERM, so service managers and container runtimes had to kill it.
3. Task admission used a separate `Load` and `Store`, so two concurrent dispatches of the same task id could both be admitted.

silverwind 2ed8cdb76e fix: stop artifact uploads depending on the cache server reaching Gitea (#1216)
Cache v2 makes the cache server the `ACTIONS_RESULTS_URL` origin, so artifact calls arrived there and were proxied on to Gitea, failing whenever it could not reach the instance.

- Artifact calls are answered with a redirect, so the cache server opens no connection to Gitea. A scheme change or an untrusted instance is still proxied, but there the cache server is the runner itself, which already reaches Gitea.
- Failures answer in twirp, not an empty `502` that clients report as `Unexpected end of JSON input`.
- `cache.v2: false` really points artifacts at Gitea now.
- Cache reservations are bound to the job that made them, so two jobs saving one key cannot commit against each other's upload, and a retry after a lost answer no longer fails a saved entry.
- The toolkit patch, which edits the GitHub-host check out of an action's bundle, was left in the shared checkout where a job running with `runner.patch_actions: false` could inherit it. It is put back after the job's copy.
- `exec` names an origin for the cache v2 it advertises, and masks its runtime token.

Behaviour changes: `no_proxy` no longer exempts `cache.external_server`, and `cache.enabled: false` also stops external registration.

Use a unique filesystem probe and preserve socket ownership. Fall back to direct access when proxying is unsupported. Preserve exec output and clean up active streams and failed starts.

Add a real Docker job test for mounted socket access, post steps and resource cleanup.

silverwindandbircni 9e3647395a feat: add GITEA_DOCKER_WORKSPACE and container cleanup (#1204)
1. Add `GITEA_DOCKER_WORKSPACE` which holds the workspace path as the daemon sees it, enabling `${GITEA_DOCKER_WORKSPACE:-.}/data:/app/data` in a compose file without having to resort to `bind_workdir` (which causes much more problems like breaking `actions/cache` because of unstable workspace paths).
2. Add container/network/volume cleanup for containers started within jobs, for example via `docker compose` inside a job. It works by running a lightweight docker socket proxy and injecting a `com.gitea.runner.job` label into every container creation and that label is used to remove containers started by that job at the end. Perf impact of this is near-zero.

1745c7c841 fix: fail the step or job whose expression cannot be interpolated (#1199)
An expression that failed to evaluate was logged and replaced by an empty string, so a `run:` step executed an empty script and reported success. The same swallow covered `shell:`, `working-directory:`, step `env:`, `with:`, `uses:`, the job's `env:`, `container:`, `services:`, `runs-on:` and outputs, and a called workflow's `with:` and `secrets:`. Every interpolation now propagates its error as actions/runner does: step-level values fail the step, job-level values fail the job at setup, `timeout-minutes` logs the error and runs unbounded, and a job or step name keeps its source text.

`defaults.run` and a called workflow's inputs and secrets are resolved once at job setup with the job context rather than per step, and the job's image is resolved once, so host mode and `ImageOS` derive from the image the job started with.

silverwind 12dc9d26a2 fix: improve behaviour across masking, commands and status (#1194)
Fixes 51 bugs discovered via comparison with `actions/runner`. Every fix has test coverage.

### Secrets

- A short secret registered no shifted-base64 form, so `base64("user:$TOKEN")` printed in the clear
- Encoded forms came only from the whole trimmed value, missing padded and per-line spellings
- Masks split only on `\n`, so `::add-mask::a%0Db` registered neither half
- Adds XML, expression-string and quote-trimming encoders

### Workflow commands

- Split at the last `::` or `]` rather than the first, so `::add-mask::a::b` registered no mask
- A command on the last line without a newline was ignored, and `::ADD-MASK::` did nothing
- `##[...]` did not decode `%3B`/`%5D`, properties lost anything after a second `=`
- `$GITHUB_ENV` and `::set-env::` now refuse `NODE_OPTIONS`

### Status

- `continue-on-error` reported failed, a cancelled job reported success, an `if:` error reported cancelled
- File commands ran after `continue-on-error`, failing the job while the step stayed green
- A bad job output aborted the whole run instead of that job

### Steps and actions

- `${{ matrix.* }}` and `${{ strategy.* }}` were empty inside composite actions
- Composite inputs leaked into nested actions as `INPUT_*`, `with:` matched case-sensitively, `pre` failures were dropped
- Docker actions dropped `runs.env` when the caller passed `with: args:`, and caller `args`/`entrypoint` beat the manifest
- An implicit shell ran with `pipefail`, a `shell:` without `{0}` passed without running
- `container.env` overrode job env and every `$GITHUB_ENV` write, heredocs lost leading blank lines, `$GITHUB_PATH` was not BOM-decoded

silverwindandbircni d9f4d65545 fix: honor volumes declared on service containers (#1186)
Service containers were built without a volume policy, so every bind and mount they declared was dropped, whatever `valid_volumes` allowed. GitHub passes a service's declared volumes straight to `docker create`, so a workflow that mounts into a service silently did nothing here. Services now get the configured policy, but not `validVolumes()`, which would also hand them the docker daemon socket that GitHub mounts only into the job container.

### What changes for users

On the default `valid_volumes: []` nothing changes: a service's volumes are still dropped, now with a warning rather than in silence. Once `valid_volumes` is configured, a service's declared volumes are honored under it instead of discarded, which is what that setting already documents. No workflow that worked before stops working, and a service can reach no volume the policy does not already allow the job container, so this is not a breaking change.
