silverwind d882311ec6 refactor: remove dead code and consolidate tests (#1335)
Removes dead code and redundant logic and consolidates tests, so there is less to read and maintain. No behavior change.

1. **act/runner**: inline single-use wrappers, compile regexes once instead of per call, embed the trampoline as a string, drop the unused legacy result of `parseActionCommand`
2. **act/container**: `sanitizeConfig` and `mergeContainerConfigs` stop returning the configs they already mutate in place, drop never-set option fields and the unused `user` parameter of `ExecWithCmdLine`
3. **act/common and cache server**: drop the unused `Trace`/`Tracef` loggers and the short SHA of `FindGitRevision`, `RegisterJob` releases through `RevokeJob`
4. **daemon, poller and reporter**: one shutdown wait for both poll modes, drop an unreachable fetch timeout branch, guard the reporter's last report time with its existing lock instead of an atomic
5. **build**: drop unused Makefile and release workflow variables, collapse the goreleaser ignore list to the same build targets
6. **tests**: fold near-duplicate tests into tables with shared setup

Throughout, hand-rolled logic gives way to `cmp.Or`, `strings.Cut`, `slices` and `min`/`max`.

Lunny Xiaoandbircni 4e8037a93b refactor(logging): use the logging package in internal (#1302)
Move the log calls in `internal` onto `logging`, and add what the process-wide logger setup and its tests need: `SetTextFormat` with a line filter for secret masking (replacing `report.MaskingFormatter`), `SetReportCaller`, `SetDefault` and `logtest.SetDefault`. After this only the `logging` package imports logrus.

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.

bircniandsilverwind 81add27459 feat(cache): add shared S3-compatible storage (#1244)
Store the cache used by `actions/cache` in an S3-compatible bucket such as AWS S3 or RustFS, with no `cache-server`. Runners with the same settings use the same cache.

A cache saved on one runner can be restored on the others within 30 seconds. The runner talks to the bucket over the S3 REST API with SigV4, without an SDK. Lifecycle rules on the bucket expire old caches.

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.

bircniandsilverwind be90c01468 feat: add size-based cache eviction (#1170)
The cache server retired entries 30 days after creation regardless of use, so a job that ran often enough to keep its cache warm still lost it on a fixed schedule. Nothing bounded the disk either.

Retention now counts from last access alone, and a repository over its limit sheds least recently accessed entries until it fits, enforced on commit as well as on the periodic sweep.

```yaml
cache:
  retention: 168h        # remove entries not accessed for seven days
  repo_size_limit: 10GB  # cap each repository
  size_limit: 0          # cap the whole cache, off by default
  sweep_interval: 1h     # minimum time between sweeps
```

Sizes accept `10GB`, `512mb`, `1TiB` or a plain byte count, binary either way. Leave a key out for its default; `0` turns a limit off, and `0s` does the same for `retention`. Whatever these allow, the cache also sheds entries to keep free space above `health_check.min_free_disk_space_mb` when health checks are enabled, so it cannot grow past the point where the runner stops accepting work.

Supporting fixes: serving an entry stamps its access time, so a find cannot hand a job a download URL for an entry the next eviction is about to remove; an entry larger than the limit is dropped on its own account rather than emptying its repository to make room; and a blob that cannot be unlinked keeps its row, so the next sweep retries instead of orphaning bytes no limit can account for.

24c13a1fd0 chore: revert 4c2ab943a8 (#1148)
Revert #1136 and use actionslib instead.

revert chore: bump the module path to `/v3`, take the version from the VCS stamp (#1136)

gitea can not consume the runner's api by version while it's version mismatches the module version:

```
go: gitea.com/gitea/[email protected]: invalid version: module contains a go.mod file,
so module path must match major version ("gitea.com/gitea/runner/v3")
```

Fix that by bumping the module version now. The existing `v3.0.0` and `v3.0.1` tags stay unusable, so a new tag is needed after this lands.

Also drop the version `-X` linker flags, which would otherwise have to repeat the new path in both `Makefile` and `.goreleaser.yaml`, where a stale path makes injection silently no-op. Go has recorded the module version in the build info since 1.24, so `Version()` reads it from there, keeping the variable as an override for builds without a VCS stamp.

That part started as https://gitea.com/gitea/runner/pulls/1137 but belongs here: the stamp resolves against the tags that are legal for the module path, so without the `/v3` bump it would report `v1.0.9-0.<ts>-<sha>`. Since `release-nightly.yml` triggers on every push to `main`, splitting them would publish a nightly with a `v1` version.

Lunny Xiaoandsilverwind 13dc9386fe Rename act_runner to runner (#850)
## Consumer-facing breaking changes

- **Go module path**: `gitea.com/gitea/act_runner` → `gitea.com/gitea/runner`. Anything importing `act/...` or `internal/...` packages (notably Gitea itself) must update imports.
- **Binary name**: `act_runner` → `gitea-runner`. Wrapper scripts, systemd units, init scripts, and documentation referencing the binary by `act_runner` will break.
- **Docker image**: `gitea/act_runner` → `gitea/runner` (incl. `*-dind-rootless` variants). Users pulling `gitea/act_runner:nightly` etc. will get stale images. Note: the image name is `gitea/runner`, not `gitea/gitea-runner`.
- **Release artifact paths**: S3 directory `act_runner/{{.Version}}` → `gitea-runner/{{.Version}}`, and artifact filenames change with the new project name. Existing download URLs break.
- **Metrics namespace**: changed from `act_runner` to `gitea_runner` (e.g. `act_runner_jobs_total` → `gitea_runner_jobs_total`); existing monitors/dashboards must be updated.
- **ldflags version path**: `gitea.com/gitea/act_runner/internal/pkg/ver.version` → `gitea.com/gitea/runner/internal/pkg/ver.version`. Affects anyone building with custom ldflags.
- **Kubernetes example resource names**: `act-runner` / `act-runner-vol` → `runner` / `runner-vol`. Users who copied the manifests verbatim will see resource churn on apply.
- **s6 service name**: `scripts/s6/act_runner/` → `scripts/s6/gitea-runner/` (image-internal; only matters for downstream image overrides).

Unchanged: YAML config field names, env vars (`GITEA_*`), CLI flags/subcommands, registration file format.

5edc4ba550 Authenticate cache requests via ACTIONS_RUNTIME_TOKEN and scope by repo (#849)
Closes #848. Addresses [GHSA-82g9-637c-2fx2](https://github.com/go-gitea/gitea/security/advisories/GHSA-82g9-637c-2fx2) and the follow-up points raised by @ChristopherHX and @haroutp in that thread.

The change is breaking only for `cache.external_server` which uses auth via a pre-shared secret.

## How auth works now

1. **Runner starts** → opens the embedded cache server on `:port`. Loads / creates a 32-byte HMAC signing key in `<cache-dir>/.secret`.
2. **Runner receives a task** → calls `handler.RegisterJob(ACTIONS_RUNTIME_TOKEN, repository)` before the job runs, defers a revoker that removes the credential on completion. Registrations are reference-counted so a stray re-register cannot revoke a live job.
3. **Job container runs `actions/cache`** → the toolkit sends `Authorization: Bearer $ACTIONS_RUNTIME_TOKEN` on every management call (`reserve`, `upload`, `commit`, `find`, `clean`). The cache server's middleware looks the token up in the registered-jobs map: miss → 401; hit → the job's repository is injected into the request context.
4. **Repository scoping** — every cache entry is stamped with `Repo` on reserve; `find`, `upload`, `commit` all verify the caller's repo matches. A job in repo A cannot see or poison a cache entry owned by repo B, even when both reach the server over the same docker bridge. GC dedup also groups by `(Repo, Key, Version)` so one repo can't age out another.
5. **Archive downloads** — `@actions/cache` does not attach Authorization when downloading `archiveLocation`, so the `find` response is a short-lived HMAC-signed URL: `…/artifacts/:id?exp=<unix>&sig=<hmac>`, 10-minute TTL, signature binds `cacheID:exp`. Tampered, expired, or foreign-secret URLs get 401.
6. **Defence-in-depth** — `ACTIONS_RUNTIME_TOKEN` is added to `task.Secrets` so the runner's log masker scrubs it from step output.

## `cache.external_server` (standalone `act_runner cache-server`)

Operators set `cache.external_secret` to the same value on the runner config and the `act_runner cache-server` config. The `cache-server` then runs with bearer auth on the cache API and exposes a control-plane at `POST /_internal/{register,revoke}` (gated by the shared secret). The runner pre-registers each task's `ACTIONS_RUNTIME_TOKEN` with the remote server before the job runs and revokes it on completion. Same per-job auth + repo scoping as the embedded handler, just over the network.

`cache-server` refuses to start without `cache.external_secret`; runner config load also fails when `cache.external_server` is set without `cache.external_secret`.

## User-facing changes

- **One-time cache miss after upgrade.** Pre-existing entries in `bolt.db` have no `Repo` stamp and won't match any job — they'll be evicted by the normal GC. First job per cache key rebuilds its cache.
- **`cache.external_server` deployments must add `cache.external_secret`.** Breaking change for anyone running a standalone `act_runner cache-server`: set the same `cache.external_secret` in both the runner config and the cache-server config. Without it neither side starts.
- **No config changes required for the default setup.** Runners using the embedded cache server (the common case) keep working without any yaml edits; the auth mechanism is invisible to workflows.

silverwindandClaude fab2d6ae04 Merge gitea/act into act/
Merges the `gitea.com/gitea/act` fork into this repository as the `act/`
directory and consumes it as a local package. The `replace github.com/nektos/act
=> gitea.com/gitea/act` directive is removed; act's dependencies are merged
into the root `go.mod`.

- Imports rewritten: `github.com/nektos/act/pkg/...` → `gitea.com/gitea/act_runner/act/...`
  (flattened — `pkg/` boundary dropped to match the layout forgejo-runner adopted).
- Dropped act's CLI (`cmd/`, `main.go`) and all upstream project files; kept
  the library tree + `LICENSE`.
- Added `// Copyright <year> The Gitea Authors ...` / `// Copyright <year> nektos`
  headers to 104 `.go` files.
- Pre-existing act lint violations annotated inline with
  `//nolint:<linter> // pre-existing issue from nektos/act`.
  `.golangci.yml` is unchanged vs `main`.
- Makefile test target: `-race -short` (matches forgejo-runner).
- Pre-existing integration test failures fixed: race in parallel executor
  (atomic counters); TestSetupEnv / command_test / expression_test /
  run_context_test updated to match gitea fork runtime; TestJobExecutor and
  TestActionCache gated on `testing.Short()`.

Full `gitea/act` commit history is reachable via the second parent.
