USER: how can i test this release action?

ASSISTANT: Testing a GitHub Actions workflow can be done in a few ways:

1. **Push to a branch:** You can push your changes to a branch and see if the workflow runs as expected. This is the most straightforward way to test a workflow, but it may not be suitable if the workflow is supposed to run on specific events like a release or a tag.

2. **Use Pull Requests:** If your workflow should run on pull requests, you can open a pull request to trigger the workflow.

3. **Use Actions tab on GitHub:** You can manually trigger a workflow run from the Actions tab in your GitHub repository. Click on the workflow you want to run, then click `Run workflow` and select the branch you want to run the workflow on.

4. **Use a workflow_dispatch event:** You can add a `workflow_dispatch` event to your workflow file to manually trigger the workflow from GitHub's UI. Here's an example of how to add it:

```yaml
on:
  workflow_dispatch:
  push:
    tags:
      - 'v*'
```

After adding this to your workflow file and pushing it to your repository, you can manually trigger the workflow from the Actions tab in your GitHub repository.

5. **Use a specific branch for testing:** If your workflow runs on a push to a specific branch, you can create a separate branch for testing. You can push your changes to this branch to test the workflow.

6. **Use act:** [act](https://github.com/nektos/act) is a tool that lets you run your GitHub Actions workflows locally. This can be useful for testing your workflows before pushing them to your repository.

Remember to remove or comment out any actions that could have side effects (like publishing a package or pushing a Docker image) when you're testing your workflows.

USER: what will github.ref be if i manually trigger?

ASSISTANT: When you manually trigger a workflow using the `workflow_dispatch` event, the `github.ref` will be set to the branch or tag you selected when you triggered the workflow.

If you didn't select a branch or tag (which is possible if your workflow file doesn't specify any `inputs` for the `workflow_dispatch` event), `github.ref` will be set to the default branch of your repository (usually `main` or `master`).

Here's an example of how you can specify an input for the `workflow_dispatch` event:

```yaml
on:
  workflow_dispatch:
    inputs:
      branch:
        description: 'Branch or tag to run the workflow on'
        required: true
        default: 'main'
```

In this example, when you manually trigger the workflow, you'll be prompted to enter a branch or tag. The value you enter will be available in the `github.event.inputs.branch` context, and `github.ref` will be set to the same value.

USER: buildx failed with: ERROR: invalid tag "***/aider:refs/tags/v0.14.2-dev1": invalid reference format

ASSISTANT: The error message indicates that the Docker tag is not valid. Docker tags cannot contain slashes (`/`), and `github.ref` includes the full Git reference, which will be something like `refs/tags/v0.14.2-dev1` for a tag.

To fix this, you can use the `github.ref_name` context instead of `github.ref`. The `github.ref_name` context contains just the name of the branch or tag without the `refs/heads/` or `refs/tags/` prefix.

Here's how you can update your workflow file:

```yaml
.github/workflows/release.yml
<<<<<<< HEAD
    - name: Build and push Docker image
      uses: docker/build-push-action@v5
      with:
        context: .
        file: ./docker/Dockerfile
        push: true
        tags: ${{ secrets.DOCKERHUB_USERNAME }}/aider:${{ github.ref }}
=======
    - name: Build and push Docker image
      uses: docker/build-push-action@v5
      with:
        context: .
        file: ./docker/Dockerfile
        push: true
        tags: ${{ secrets.DOCKERHUB_USERNAME }}/aider:${{ github.ref_name }}
>>>>>>> updated
```

This will tag the Docker image with just the name of the branch or tag that triggered the workflow run, which should be a valid Docker tag.
