Support cache-dependency-paths outside the current directory

[PeterJCLaw]

Description:

I'm building a composite Action which uses actions/setup-python internally. When specifying the requirements.txt from the action setting up Python fails, though I thiiink I'm passing the right values.

Here's what I've got:

    - name: Set up Python
      uses: actions/setup-python@v3
      with:
        python-version: '3.10'
        cache: pip
        cache-dependency-path: ${{ github.action_path }}/requirements.txt

Here's the error I get:

No file in /home/runner/work/sr2022-comp/sr2022-comp matched to [/home/runner/work/_actions/PeterJCLaw/srcomp-validate-action/bd809ff12b77607cc2f0ebbd035d6f0a5c8d32fc/requirements.txt], make sure you have checked out the target repository

sr2022-comp is the repo I'm using to test the action, srcomp-validate-action is the action.

My specific use-case only has a couple of dependencies so #351 would likely work as a fix, though I can imagine that a more complex scenario would want this to work.

Platform: Ubuntu

I'm currently working around this by coping the requirements file into a temporary directory within the working directory and then referencing that, instead of the original. This doesn't feel like a great solution though as it ends up polluting the target repo's working copy.

Hello @PeterJCLaw. Thank you for your report. Could you please provide a public repository to reproduce the issue ?

[dmitry-shibanov]

Hello @PeterJCLaw. Actually, I think the root cause of the issue in the toolkit/glob package. The hashFiles function tries to compare if the passed directory matches with GITHUB_WORKSPACE. The composite action's directory and checkout project's directory don't match, that is why if does hash the file and the actions setup-python throws an error.

Thanks for your replies.
For completeness the repos in question are:

• https://github.com/PeterJCLaw/srcomp-validate-action/
• https://github.com/srobo/sr2022-comp/ (specifically Make use of compstate validation action srobo/sr2022-comp#5)

I've raised actions/toolkit#1035 for the underlying issue.

Hello @PeterJCLaw. For now I'm going to close the pull request because the root cause of the issue comes from the toolkit repository. If you have any concerns feel free to ping us.

@dmitry-shibanov would you be open to reopening this issue? It looks like hashFiles has a new parameter now which allows callers to specify the workspace directory (actions/toolkit#1318), which I think would help here?

[dmitry-shibanov]

Hello @PeterJCLaw. In this case I'm coming to reopen the issue to investigate it one more time.

edit: Sorry for edit in the first glance I thought it was a pull request.
