Revert "chore(cleanup): lxc-helpers does not need a global lock (#1047)" (#1103)
This reverts commit 996ac343ee.

The lock is still needed to guard against the following scenario.

d92a892ece/act/runner/run_context.go (L225-L236)

- two or more jobs start
- one of them creates the act template (`lxc_build_template $(lxc_template_release) $name`) - lxc-helpers now has transactions and they won't race against each other
- once it is built all jobs will then try to install node in the container that was just built and race against each other

with a global lock only the first one will build and populate the act template. The other will then do nothing because it already exists.

The bug can trivially be reproduced with:

```yaml
on:
  pull_request:

jobs:
  test1:
    runs-on: lxc
    steps:
      - run: echo OK1
  test2:
    runs-on: lxc
    steps:
      - run: echo OK2
  test3:
    runs-on: lxc
    steps:
      - run: echo OK3
```

Forgejo Runner

A daemon that connects to a Forgejo instance and runs jobs for continuous integration. The installation and usage instructions are part of the Forgejo documentation.

Reporting security-related issues

Sensitive security-related issues should be reported to security@forgejo.org using encryption.

License

The Forgejo runner is distributed under the terms of the GPL version 3.0 or any later version.

Architectures & OS

The Forgejo runner is supported and tested on amd64 and arm64 (binaries and containers) on Operating Systems based on the Linux kernel.

Work may be in progress for other architectures and you can browse the corresponding issues to figure out how they make progress. If you are interested in helping them move forward, open an issue. The most challenging part is to setup and maintain a native runner long term. Once it is supported by Forgejo, the runner is expected to be available 24/7 which can be challenging. Otherwise debugging any architecture specific problem won't be possible.

Hacking

The Forgejo runner is a dependency of the setup-forgejo action. See the full dependency graph for a global view.

Building

  • Install Go and make(1)
  • make build

Linting

  • make lint-check
  • make lint # will fix some lint errors

Testing

The workflow that runs in the CI uses similar commands.

Without a Forgejo instance

  • Install Docker
  • make test integration-test

The TestRunner_RunEvent test suite contains most integration tests with real-world workflows and is time-consuming to run. During development, it is helpful to run a specific test through a targeted command such as this:

  • go test -count=1 -run='TestRunner_RunEvent$/local-action-dockerfile$' ./act/runner

With a Forgejo instance

  • Run a Forgejo instance locally (for instance at http://0.0.0.0:8080) and create as shared secret
export FORGEJO_RUNNER_SECRET='AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA'
export FORGEJO_URL=http://0.0.0.0:8080
forgejo forgejo-cli actions register --labels docker --name therunner --secret $FORGEJO_RUNNER_SECRET
  • make test integration-test # which will run addional tests because FORGEJO_URL is set

end-to-end

  • Follow the instructions from the end-to-end tests to run actions tests locally.
  • ./end-to-end.sh actions_teardown # stop the Forgejo and runner daemons running in the end-to-end environment
  • ( cd ~/clone-of-the-runner-repo ; make build ; cp forgejo-runner /tmp/forgejo-end-to-end/forgejo-runner ) # install the runner built from sources
  • ./end-to-end.sh actions_setup 13.0 # start Forgejo v13.0 and the runner daemon in the end-to-end environment
  • ./end-to-end.sh actions_verify_example echo # run the echo workflow
  • xdg-open http://127.0.0.1:3000/root/example-echo/actions/runs/1 # see the logs workflow
  • less /tmp/forgejo-end-to-end/forgejo-runner.log # analyze the runner logs
  • less /tmp/forgejo-end-to-end/forgejo-work-path/log/forgejo.log # analyze the Forgejo logs
