When the probe's deadline expired during `ContainerCreate`, dockerd still created the container but the probe never got its ID, leaving it in `Created` with its image's anonymous volumes. A slow daemon leaked one per job.
The probe now runs detached with its own timeout, so the create is never cancelled and the container is always removed. Callers still fall back after their own deadline, and the runner waits for pending probes before exiting.

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`.

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.

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.

`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.

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.

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.

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

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.

The runner's own `container.options` and the workflow's were joined into one string before parsing, so the host-escape filter added in https://gitea.com/gitea/runner/pulls/1058 dropped the administrator's options along with the workflow's. Setups that need `--device` or `--security-opt` from the config file had no way left to get them short of enabling privileged mode.
`NewContainerInput` now carries the two sources apart, as `RunnerOptions` and `WorkflowOptions`, down to the point where the filter runs. With privileged mode off, the host-escape fields are reset to what the runner's own options parse to on their own, so only the workflow's contribution is dropped.
Three further ways a workflow's options reached past its container, all resolved on the runner before anything reaches the daemon:
1. `--env-file` and `--label-file` name files that are read on the runner, so any file it could read became container environment or labels. Both are refused from a workflow now, and still serve the runner's own options.
2. A bare `--env NAME` was resolved from the runner's own environment by docker's validator. That lookup is gone, for every source. Use `runner.envs` or `runner.env_file` to pass a variable on.
3. A volume driver decides for itself what it mounts, and the local driver's `device=` option turns a name `valid_volumes` allows into a bind of any host path. A workflow's mounts may no longer carry one.
`--isolation`, `--volume-driver` and the two paths `--security-opt systempaths=unconfined` lands in were also missing from the fields a workflow may not set.
Last, the `--network and --net in the options will be ignored.` warning fired for every container, because the runner's own network mode is fed into the parsed options before the check runs.

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:

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>`.

Service containers were started and then left alone, so a job's first step could run while a database was still starting up. The runner now waits for every service whose image or `options` declare a healthcheck, as GitHub does. An unhealthy service fails the job with its container log, one that never becomes healthy fails it after `container.service_ready_timeout` (default `5m`, negative disables the wait), and one that exits without a healthcheck only gets its log and a warning.
The started containers also fill the `job` context, whose fields existed but were never populated: `job.container.{id,network}` and `job.services.<id>.{id,network,ports}`. `ports` is keyed by the plain container port, so `job.services.postgres.ports['5432']` resolves to the host port Docker picked.

`CopyTarStream` creates the destination directory by extracting a one-entry tarball with `DestinationPath: "/"`, but named that entry with the absolute `destPath`. Docker Engine 29.5+ tightened path validation on the copy API and rejects absolute entry names against a `/` destination with `statat var/run/act/actions/<sha>: path escapes from parent`, so the action directory never reached the job container and `actions/checkout` failed during "Set up job". Stripping the leading slash makes the entry relative, matching what the sibling `copyDir` already does and the upstream fix in nektos/act v0.2.89. Adds a regression test asserting the mkdir tarball entry is relative.

Workflow-controlled `jobs.<job>.container.options` were merged directly into the
Docker `HostConfig`. When the runner's privileged mode is disabled, only
`Privileged` was forced to `false` — host namespace flags, capability expansion,
security-profile overrides, and device/runtime access from the workflow YAML
survived into the final `HostConfig`. A workflow author could therefore enter
host PID/IPC namespaces and execute commands as root on the runner host:
```yaml
container:
image: ubuntu:22.04
options: >-
--pid=host --ipc=host --cap-add=ALL
--security-opt seccomp=unconfined --security-opt apparmor=unconfined
```
## Fix
`mergeContainerConfigs()` now strips the dangerous options-derived `HostConfig`
fields before merging when privileged mode is off: `PidMode`, `IpcMode`,
`UTSMode`, `CgroupnsMode`, `UsernsMode`, `CapAdd`, `SecurityOpt`, `Devices`,
`DeviceCgroupRules`, `DeviceRequests`, `VolumesFrom`, `Runtime`, `CgroupParent`,
and `Sysctls`. Each strip emits a warning, matching the existing
`--network ignored` handling. Options remain honored when privileged mode is
enabled, since the administrator has already opted into host access.

Leaked per-job networks each hold a subnet of the daemon's address pool and nothing reclaimed them, so a host eventually fails every job with `all predefined address pools have been fully subnetted`. This is what CI hit in https://gitea.com/gitea/runner/actions/runs/742177.
- teardown no longer loses a container, and its network with it: a failed `ContainerRemove` was reported as success, a container whose id was never learned was skipped, and the daemon's own `AutoRemove` teardown was raced
- the idle cleanup reclaims what teardown cannot: networks carry `com.gitea.runner.uuid`, so a runner only touches its own, and a cutoff keeps a job starting during the pass out of scope
- pull failures reported mid-stream were discarded, surfacing later as a confusing `No such image`; they now propagate, and fall back to a local copy instead of failing the job
- `NetworkCreate` retries pool exhaustion briefly, then says which knobs to turn
- digest-pinned images are not re-pulled, and removal kills first so it never waits out Podman's stop timeout (measured 10.1s → 0.09s per container)

1. Docker rejects two mounts on one target, so a `container.volumes:` or `--volume` aimed at `/opt/hostedtoolcache` failed the job with `Duplicate mount point`. Job and service volumes now displace the mount on the same path, and `name:/target:ro` no longer mounts read-write at the literal path `/target:ro`.
1. Setting `RUNNER_TOOL_CACHE` only changed what the variable said, the cache stayed where it was, so tools writing to it landed outside the mount and `${{ runner.tool_cache }}` disagreed with the variable. It now relocates the cache. Leaving it unset behaves as before.
1. Unknown `config.yaml` keys now warn instead of being dropped without a trace.

Containers set `HostConfig.AutoRemove` but act also removes them explicitly, so the two removers race and the loser logs a 409 `removal of container X is already in progress` — seen at the end of nearly every `uses: docker://` step.
The explicit remove is redundant for `docker://` steps and docker actions (`Start(true)` already awaited exit), so it's skipped. Job and service containers keep both removers — their `sleep` entrypoint needs `AutoRemove` as a fallback reaper — so there the race is inherent and `remove()` now treats `NotFound` and `Conflict` as success.

## Problem
Several runner code paths could drop the **tail** of a step's log output, so a
failing (or cancelled) step would show output that is missing its last line(s).
This was observed in practice and traced to four independent issues.
## Root causes & fixes
### 1. Trailing line without a newline was never flushed
`common.lineWriter` buffers output until it sees a `\n`. A final line **without**
a trailing newline (e.g. an error message printed right before a process exits,
a panic, `printf` without `\n`) stayed in the internal buffer and was never
emitted — the writer exposed no flush at all.
- Added `lineWriter.Flush()` (idempotent), a `Flusher` interface, and a
`FlushWriter(io.Writer)` helper.
- Flush at every stream EOF: the exec copy goroutine, the container `attach()`
streaming goroutine, and at step end (`useStepLogger`).
### 2. Cancellation/timeout truncated output
`waitForCommand` returned immediately on `ctx.Done()` and abandoned the
output-copy goroutine, losing output the command had already produced. It now
drains with a bounded grace period before returning. The response channel is
buffered so the goroutine can't leak if the drain times out.
### 3. `attach()` raced the final bytes
Container output was streamed in a fire-and-forget goroutine that `wait()` did
not synchronize with, so the step could proceed before the last bytes were
written. `wait()` now blocks on the streaming goroutine (bounded) so output is
fully drained and flushed first.
### 4. `::stop-commands::` silently dropped lines from the step log
Lines between `::stop-commands::<token>` and its end token were echoed without
the `raw_output` field **and** short-circuited the handler chain (`return false`),
so they never reached the step log (non-raw entries aren't appended while a step
is running). Now returns `true` so they are still captured.

`containerReference.id` was cached from `Create()` and never re-validated, so a container torn down out-of-band (AutoRemove on an unexpected exit, daemon-side cleanup, sibling-job race in a parallel matrix) left a stale id behind. The next `Copy`/`Exec` then hit the daemon with that dead id and failed the otherwise-successful job with `Could not find the file /var/run/act/ in container <id>`.
`find()` now `ContainerInspect`s the cached id and clears it only on a definitive `NotFound`; transient errors trust the cache so cleanup pipelines don't abort on a daemon blip. Operations that need a live container (`copyContent`/`copyDir`/`CopyTarStream`/`exec`/`GetContainerArchive`) fail fast with a clear `container "<name>" does not exist` instead of the daemon's generic empty-id error.

Running the full suite under `-race` (dropping `-short`) exposed pre-existing data races in parallel matrix-job execution, fixed by not sharing mutable state across combinations:
- `containerDaemonSocket()`/`validVolumes()` derive per-job values instead of mutating shared `Config`
- `getWorkflowSecrets` builds a fresh map, `rc.steps()` clones each step, and go-git workdir access is serialized
- every write to a shared `Job`'s result/outputs runs under a per-`Job` lock, each combo interpolating outputs from a pristine snapshot (last wins, as on GitHub)
### Test suite
- capability gates (docker / network / host-tools / Linux) replace the `-short` skips, and the suite runs offline via local fixtures (the artifact flow uses an in-process loopback server, only the docker-action force-pull needs the network)
- drops redundant tests, adds a regression test for https://gitea.com/gitea/runner/issues/981 and a docker-in-docker harness (`make test-dind`)

Fixes: https://gitea.com/gitea/runner/issues/859
Migration approach mirrors [actions-oss/act-cli#154](https://github.com/actions-oss/act-cli/pull/154).
### Dependency changes
- `github.com/docker/docker` v25.0.15 → **removed** (v29 doesn't exist as docker/docker; the project moved to moby/moby)
- `github.com/docker/cli` v25.0.7 → v29.4.3
- `github.com/docker/go-connections` v0.6.0 → v0.7.0
- `github.com/docker/docker-credential-helpers` v0.9.5 → v0.9.6
- `github.com/moby/go-archive` added at v0.2.0
- `github.com/moby/moby/api` added at v1.54.2
- `github.com/moby/moby/client` added at v0.4.1
- `github.com/moby/buildkit` removed (only used `dockerignore.ReadAll`, swapped for `moby/patternmatcher/ignorefile.ReadAll` directly)
- `github.com/containerd/errdefs` v0.3.0 → v1.0.0
### Migration
- v28: type aliases moved to their subpackages (`types.{Container,Image,Network,Exec}*` → `container/image/network/...`); deprecated APIs replaced (`ImageInspectWithRaw`, `client.IsErrNotFound`, `archive.CanonicalTarNameForPath`, `opts.ValidateMACAddress`, `ListOpts.GetAll`)
- v29: structural client redesign — every `cli.X(ctx, ...)` call switched to options-everywhere/Result-typed signatures, `ContainerExec*` → `Exec*`, `ContainerWait` returns a struct with `Result`/`Error` channels, `Tty`→`TTY`, `Copy*Container` takes options struct, `client.NewClientWithOpts` → `client.New`. `pkg/stdcopy` moved to `moby/moby/api/pkg/stdcopy`. The vendored copy of `cli/command/container/opts.go` was refreshed from cli v29 (now uses `netip.Addr` for IPs, port-set conversion helpers). A small local `parsePlatform` helper centralises the `os/arch[/variant]` parsing previously inlined into multiple call sites.
### Behaviour preservation
The migration introduced several behavioural shifts vs the v25 client; all were caught in review and reverted/fixed in follow-up commits:
- `GetDockerClient`: cli v29's `Ping(NegotiateAPIVersion: true)` returns errors that the old `NegotiateAPIVersion` silently swallowed. Restored best-effort behaviour (warn-log + continue) so daemons with blocked `_ping` or API < 1.40 keep working. The SSH-helper `client.New` call no longer inherits `client.FromEnv`, matching the old `NewClientWithOpts(WithHost, WithDialContext)` so `DOCKER_API_VERSION`/`DOCKER_TLS_VERIFY` don't leak into the SSH-tunneled client
- `parsePlatform`: malformed input now returns an explicit error instead of silently dropping to "no platform constraint" and pulling the host-default architecture. Single-segment (`"linux"`), 4+-segment (`"linux/arm/v7/extra"`), and trailing-slash (`"linux/arm/"`) inputs are all rejected
- `LoadDockerAuthConfig`/`LoadDockerAuthConfigs`: `config.LoadDefaultConfigFile(nil)` panics on a malformed config file (it does `fmt.Fprintln` on the nil `io.Writer`). Switched to `config.Load(config.Dir())` so load errors reach the logger and the panic path is gone. Restored the old behaviour of returning `config.Load` and `GetAuthConfig` errors to the caller (the v29 refactor had silently downgraded them to warn-only). A `reference.ParseNormalizedNamed` failure on the image string falls through to the `docker.io` default rather than aborting, since the old string-based hostname extraction was infallible
Test assertions also updated for two upstream error-message string shifts (`go-connections` port-range parser; `cli/opts` envfile BOM check). Added unit-test coverage for the new `parsePlatform` helper, locking in the intentional limits (single-segment, 4+-segment, and trailing-slash platforms rejected).

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.
