The Kubernetes backend copies actions and other files into the job container with `tar` over `pods/exec`, so the data goes through the API server, which on managed clusters often sits in other zones than the nodes (each copied byte then crosses zones twice). Actions are megabytes of JavaScript bundles that gzip about fivefold:
| Action | tar | gzip |
|---|---|---|
| actions/setup-go@v5 | 8.0 MB | 1.5 MB |
| actions/cache@v4 | 11.6 MB | 2.0 MB |
| actions/setup-java@v4 | 15.3 MB | 2.5 MB |
| docker/build-push-action@v6 | 12.9 MB | 3.0 MB |
The startup probe now also reports whether the job container has `gzip`. If it does, `CopyDir` and copies of 64 KiB or more are gzipped at `BestSpeed` and extracted with `gzip -dc | tar -xf -`. Smaller copies (run scripts, file command files) stay uncompressed, where gzip would save next to nothing and cost a process in the pod. Images without `gzip` keep the plain tar stream, so the image requirements do not change.
This is independent of #1354 and gets most of its traffic saving with no new moving parts.

`exec` forwarded the toolkit's ArtifactService calls to an instance it never registered, and its random runtime token held no backend IDs, so `actions/upload-artifact` and `actions/download-artifact` v4 and later failed.
The local artifact server now serves the v4 API, including the single Put Blob uploads docker/build-push-action uses. `exec` gives each workflow its own unsigned JWT runtime token and artifact run, so artifact names conflict and carry over between runs as on GitHub. Artifacts default to a temporary directory instead of the workspace that jobs copy.

`uses:` steps and job hooks kept their "Run …" group open until they finished. Gitea doesn't nest groups, so the action's own first `::group::` closed the header and everything before it stayed hidden there, e.g. all of goreleaser's output in https://gitea.com/gitea/cli/actions/runs/1121069/jobs/1519275. The header group now closes right after its details, as in actions/runner.
The action header also matches actions/runner's otherwise now: it is titled by the `uses:` reference, lists the resolved inputs including `action.yml` defaults without empty ones, is shown for pre stages too, and post stages start with `Post job cleanup.`.

Without a docker daemon six `act/runner` tests failed instead of passing. A dry run still created and removed job networks, the job teardown dropped the dry-run flag along with every other context value, and the container mocks asked the daemon for the runner arch.
This also speeds up the tests and CI without dropping assertions. Most of the time went to git and docker round trips, which are now pinned, batched or coalesced, and the dind and e2e steps cache or overlap more of their setup. On CI, `act/runner` went from 77s to 55s and `test-dind` from 108s to 55s. Locally, `act/runner` without docker went from 53s to 7s.

The toolkit patch rewrote bundles in place in the shared action cache. Since https://gitea.com/gitea/runner/pulls/1316 trees are never refreshed, so a bundle left truncated failed every later job using it.
Patched bundles now only overwrite the job container's copy, so the runner no longer writes to an extracted tree.
Extraction records each file's size beside the tree, and a tree that no longer matches is fetched again, offline mode included, as a missing one always was. This also catches damage from outside the runner, such as storage losing a write, for a stat per file, a fraction of the copy each stage already makes. Trees from older runners have no record and download once more, except in offline mode, which keeps using them as before.

Contains a number of small bug fixes where jobs behaved differently from GitHub or failed silently.
1. Hooks fail on a refused `::set-env::` or `::add-path::` and no longer inherit the last step's identity
1. Docker build, exec and wait errors are returned instead of swallowed, token-only registry credentials work, logs of `--tty` services decode
1. Env files split lines like GitHub on each OS, so a carriage return is kept on Linux and CRLF ends a line on Windows, empty heredoc names or delimiters are rejected
1. Post steps run after their pre step even when main was skipped, composites see undeclared inputs, `runs.args` wins without `with.args` being parsed
1. Docker actions skip evaluating defaults of inputs given in `with` and read `entryPoint` and `args` in any case, a lowercase `dockerfile` is found, undeclared inputs get GitHub's warning
1. A user-set `CI` is kept, `GITHUB_REPOSITORY_ID` and the other missing `GITHUB_*` variables are exported
1. `timeout-minutes` can read the step's own `env`, a step-level `ACTIONS_ALLOW_UNSECURE_COMMANDS: false` beats a job-level `true` while the runner's own opt-in still wins, `pwsh` quotes the script path
1. A step `env:` given as one expression such as `${{ fromJSON(matrix.env) }}` is applied, `hashFiles` fails with GitHub's messages on script errors and after 120 seconds, a job image without node still gets an empty hash
1. A step whose command files cannot be reset fails instead of importing stale ones, a timeout between steps fails the job instead of reporting success
1. One named volume can be mounted at several paths, host-mode PTY steps keep their last output when they fail, host scratch directories are removed when job setup fails
1. Cancelling a step right after it starts kills its whole process tree
1. Cache prefix restores pick the newest entry created within the same second, also on S3, cache commits with a wrong size are rejected
1. Artifact chunks are written at their offset, download URLs are escaped, listing a run without artifacts no longer crashes
1. Poll backoff reaches `fetch_interval_max`, proxy passwords are masked in more forms, secrets are also masked in step names and in their quoted form in the runner log, a failed final report is logged
1. On Windows hosts a differently cased unsecure-commands opt-in or proxy variable counts, and an early cancel no longer leaks a job object handle
1. Interactive `register` prompts for a missing token and stops on SIGTERM, `exec --list --detect-event` no longer panics without events, `config set` works on `cache.s3` keys

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`.

The on-disk layout stays the same, so existing caches keep working, and the index buckets bolthold left behind are dropped on the first sweep. Queries now run against an in-memory copy of the entries that is only re-read after another process wrote to the store, so lookups and sweeps no longer decode the whole store.

Commands the runner applies itself, like the `::set-output::` older actions still print, showed up raw in the job log. The reporter also re-parsed every line with one job-wide stop-commands and echo state, while act keeps one command handler per step, stage, composite child and hook, as GitHub does. A `::stop-commands::` left active in one of them kept the reporter suppressed for the others, so their `::add-mask::` values were never registered, and post steps logged command lines twice.
- act's command handler decides what reaches the log, as GitHub's runner does: applied commands only under `ACTIONS_STEP_DEBUG` or `::echo::on`, `::stop-commands::` and its resume line shown with long tokens masked
- Masks go straight to the reporter, which no longer parses command lines
- One parser follows GitHub's rules: leading whitespace, `##[...]` anywhere in a line, registered commands only
- Service logs honour only `::add-mask::`

After https://gitea.com/gitea/runner/pulls/1304, logrus stayed only to forward logs from docker/cli and moby/go-archive. The runner used a small part of those: volume parsing, the build context tar, the `ssh://` connection and registry credentials. Own code that matches them replaces them, so logrus leaves the module graph. docker/cli stays for its logrus-free `opts` and `connhelper/ssh` packages.
Other dependencies that the standard library or existing ones cover go too: mergo, httprouter (replaced by `http.ServeMux`), retry-go, go-isatty, go-selinux, container-device-interface, gotest.tools and go-cmp (replaced by testify). The binary shrinks by 5%.
Behaviour differences:
1. An unreadable file in a build context is skipped with a warning, where go-archive left a truncated tar.
2. Build contexts no longer carry `security.capability` xattrs.
3. The cache and artifact servers answer HEAD on GET routes, and no longer redirect trailing slashes or answer OPTIONS.

On Kubernetes a service is reached by its id made a DNS label, so some service ids might become unreachable. For example, the `devstoreaccount1.azurite.local` service of Gitea's [MSSQL tests](2fe74d3cdd/.github/workflows/pull-db-tests.yml (L229)) is only in the pod's hosts as `devstoreaccount1-azurite-local`, while the tests connect to the id as written. Container names must be DNS labels, but `hostAliases` accepts DNS subdomains, so an id that is one is now added there too, and to `no_proxy`, as on Docker where a service is reached by its id.
The warning for a service not reachable by its id now also covers ids that differ only in case, as Kubernetes hostnames are lowercase.

Job teardown ran every step on one shared minute. When removing the job container took longer, the network removal ran on an expired context and the network stayed behind until the orphan reclaim, which only takes networks older than `workdir_cleanup_age`, 24h by default. All that time it held a subnet of the daemon's address pool.
The job and service containers are now removed in parallel, and the docker proxy sweep, the network and the volumes get a fresh budget after them. The idle reclaim takes unused networks and volumes once they are 10 minutes old, and network removal treats a network that is already gone as removed.

Each step refreshed its own clone of an action, so a composite using one action repository ten times fetched it ten times per job, and a single network error failed the job.
Like actions/runner, a job now downloads each action repository and ref once, as an archive extracted into a directory per commit. Each action still gets its own copy in the job container. This restores the per-job dedupe of https://gitea.com/gitea/runner/pulls/1178, which only reached a since-deleted branch.
How a download works:
1. The action URL is taken after `insteadOf` rewriting, as git would use it.
2. The archive comes from `<url>/archive/<ref>.tar.gz`, or from codeload.github.com for github.com, as for actions/runner.
3. A cached tag or branch is revalidated with its ETag, which GitHub and Gitea 28+ answer with a 304. A cached commit pin needs no request.
4. Transient failures (5xx, 408, 429 honouring `Retry-After`, dropped transfers) are retried three times with a 10 to 30 second backoff.
5. Git takes over, cloning and exporting the commit into the same directory layout, when the URL is not HTTP(S), the ref is a short commit, the host serves no usable archive, the host cannot be connected to, or the retries run out.
Median of 3 runs, git (shallow clone, then fetch) against archives, on a cold and a warm cache:
| Action | git cold | git warm | archive cold | archive warm |
|---|---|---|---|---|
| github.com actions/checkout@v4 | 937ms | 726ms | 286ms | 171ms |
| github.com actions/cache@v4 | 1006ms | 801ms | 516ms | 161ms |
| github.com actions/setup-node@v4 | 1046ms | 786ms | 463ms | 156ms |
| gitea.com actions/checkout@v4 | 2007ms | 1165ms | 667ms | 222ms |

Gitea derives the steps of a job from the workflow file, so the `pre` and `post` steps of actions only show up inside "Set up job" and "Complete job", see https://github.com/go-gitea/gitea/issues/24604.
The runner now also reports the steps as it runs them (https://gitea.com/gitea/actions-proto-def/pulls/19): "Set up job", a "Pre" and "Post" step for each action that has one, the workflow steps with their evaluated names, and "Complete job", as actions/runner shows them. The per-step state Gitea reads today is unchanged, and the job log only moves "Complete job name" and "Matrix:" ahead of the pre steps, so older Gitea versions keep showing everything as before. Job hooks and containers stay part of "Set up job" and "Complete job".

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`.

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.

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.

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.

Support tmpfs in container `options` via `--mount type=tmpfs,...`, like GitHub does. The `valid_volumes` check silently dropped these mounts because they have no source. A tmpfs is backed by memory and exposes nothing from the host, same as `--tmpfs`, which already passes. Every other mount still goes through the allowlist.
Both forms now work:
```yaml
services:
mysql:
image: mysql:8.4
options: --tmpfs /var/lib/mysql # already worked
```
```yaml
services:
mysql:
image: mysql:8.4
options: --mount type=tmpfs,destination=/var/lib/mysql # was dropped, now works
```

The Kubernetes backend extracted CopyDir archives at "/" with entries like
"var/run/act/actions/<sha>/...". Ubuntu's patched tar refuses to extract
through an absolute symlink, failing with "Invalid cross-device link" on
images that link /var/run to /run, so actions never reached the job
container. Extract at the destination with relative entries instead, like
Copy already does.
This is a similar issue to #1128, but for k8s instead of Docker.
I built the image and deployed it to my k8s cluster to verify the fix.

- Docker actions evaluate `runs.args` and `runs.env` with their own `inputs`, so a same-named `workflow_dispatch` input no longer replaces the step's `with:` value
- Dockerfile action images are tagged per step and job and removed afterwards, so changed Dockerfiles rebuild and concurrent jobs never share an image
- Workflow and job `env` are evaluated before job and service container credentials and service `env` use them
- Docker actions in host jobs get the host workspace and file-command directory mounted, and no longer inherit the runner's own `PATH`
- Cache server address detection accepts a single interface address

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.

1. Host mode is selected only through `runs-on` again, as in upstream act.
1. A workflow volume that `valid_volumes` drops no longer displaces the runner's own socket, workspace, tool cache or `/var/run/act` mount, so `/var/run/docker.sock:/var/run/docker.sock` works on hosts whose daemon socket lives elsewhere.
1. `docker://` is stripped from job and service images, as on GitHub.
1. Each created service's log is printed at job end, and service log dumps no longer run workflow commands, as on GitHub.
1. A `--privileged` dropped because privileged mode is off now logs a warning.
1. README: the proxy variables change per step through `env:` or for the rest of a job through `$GITHUB_ENV`, `container.env` does not override them.

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.

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.

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.

`valid_volumes` patterns now match with doublestar instead of gobwas/glob, which was compiled without separators so `*` crossed slashes. doublestar is already in the module graph, keeps `*` within one path segment and matches host paths with the OS separator, which fixes Windows patterns where a backslash was read as an escape.
Breaking: a host pattern that relied on `*` matching nested paths needs `**`, e.g. `/data/**` instead of `/data/*`. Named volumes and the bare `**` are unaffected.
