🧭 Overview

This repository is the central collection of reusable automation for TirSystem repositories. The primary repository lives at git.tirsystem.com (Gitea) and is push-mirrored to GitHub.

It currently contains the Gitea workflow sync-github-metadata.yml, which copies the repository description and topics from Gitea to the GitHub mirror on every push to main, on manual dispatch, and daily at 03:17 UTC.

📋 Requirements

• A Gitea instance with Actions enabled and a runner providing ubuntu-latest with python3
• A configured GitHub push mirror on the Gitea repository (exactly one)
• Repository secrets:
  • TOKEN_FOR_GITEA: Gitea API token (plain string, or JSON with GITEA_TOKEN)
  • CREDENTIALS_FOR_GITHUB: JSON object containing GITHUB_PAT, a GitHub personal access token allowed to edit the mirror repository

🛠️ Setup

No dependencies need to be installed; the workflow uses only the Python standard library.

1. Clone the repository:

   git clone ssh://git@git.tirsystem.com:10022/TirSystem/github-action.git
   

2. Add the secrets listed under Requirements to the repository settings in Gitea.
3. Configure the GitHub push mirror in the repository settings.

▶️ Run

Workflows run automatically on push to main and on the daily schedule. To run manually, trigger Sync GitHub mirror metadata via workflow_dispatch from the Actions tab in Gitea.

🧪 Tests

The workflow files and the Python embedded in them are validated by offline tests that need no network access and no secrets:

python3 -m venv .venv
source .venv/bin/activate        # Windows PowerShell: .venv\Scripts\Activate.ps1
python -m pip install -r tests/requirements.txt
python -m pytest -q tests

The same checks run on every pull request and push to main through validate-workflows.yml. They parse every workflow as YAML, compile the embedded Python, require explicit job permissions, and test credential parsing, push mirror address parsing and the sync flow against a fake API.

After a change to the sync workflow, also trigger Sync GitHub mirror metadata manually in Gitea and compare the description and topics on the GitHub mirror.

🟢 Capabilities

Only the first row is implemented. The rest is planned and tracked in the Project Plan, which also describes each use case.

Capability	Status
Synchronize repository metadata (Gitea to GitHub mirror)	Implemented in .gitea/scoped_workflows/, with offline tests and a validation workflow
Configure and validate workflow credentials	Partial: secrets are checked for format only
Onboard a repository, manage runners, diagnose failures	Planned (MIL-002)
Shared quality checks	Planned (MIL-003)
Versioned release and publishing	Planned (MIL-004)

🔄 Sync GitHub metadata

Syncs the Gitea repository description and topics to the GitHub push mirror.

🕒 Cron

Daily at 03:17 UTC (17 3 * * *), plus every push to main and manual workflow_dispatch.
