hashFiles() couldn't finish within 120 seconds.

(filing here since I understand that hashFile() is owned by https://github.com/actions/runner)

Hey!

We have migrated a semi-large Unity project from SVN to Git / Github and I am working on setting up Actions for a build pipeline. Unfortunately, a step to create a cache for Unity-specific files is giving me a headache. If I understand the error message correctly, I am running into a 120 second timeout for that step.

As I see it, the timeout for hasFiles() is set here and there is no way to increase it, is that correct? https://github.com/actions/runner/blob/100c99f2635be35c7ea690c58fa7d203725cac9e/src/Runner.Worker/Expressions/HashFilesFunction.cs#L16

Expected behavior I imagine it makes a lot of sense that the job has a timeout. It would be helpful if it could be set from the step configuration for scenarios where a lot of files have to be hashed.

@JJ: Assuming that the runtime is performing hashFiles() at step evaluation, you should be able to perform your own hashing on disk in a step…

      - name: Cache Maven dependencies
        uses: actions/cache@v2
        with:
          path: ~/.m2/repository

1. This isn’t tested
2. find, xargs, shasum might not be available for your OS/Shell, as applicable you may need to replace the commands…
3. Please don’t randomly trust random people’s code w/o inspecting / considering it 😄
