Fix "reference not found" error

[lufia]

If an action uses the branch to pin the major version, for example - use: 8398a7/action-slack@v3
will stop with an error: "v3: reference not found."

In this case act should use refs/remotes/origin/v1 as a name to resolve v1 revision.

#311

I checked:

• In b3299ec (current master) stopped by - use: 8398a7/action-slack@v3
• This patch fixed the above error.

I'm very interested in getting this fixed as well, thanks for providing a pr @lufia . Testing locally, I'm still seeing failures. In this case I'm trying to use the main branch:

jobs:
  image:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2

    - uses: anchore/scan-action@main
      with:
        image: "python:3.8"
        debug: true

This fails in the same way as before:

[[Demo] Run Scan Action/image] ⭐  Run anchore/scan-action@main
[[Demo] Run Scan Action/image]   ☁  git clone 'https://github.com/anchore/scan-action' # ref=main
[[Demo] Run Scan Action/image]   cloning https://github.com/anchore/scan-action to /Users/alfredo/.cache/act/anchore-scan-action@main

@alfredodeza Thanks for your testing! I will check this case.

I'm having the same problem with jurplel/install-qt-action@v2

Hi. @alfredodeza

I'm trying to represent the error. Unfortunately, I got success with above configuration.

% cd src/nektos/act
% go build -o test-act
% cat testdata/scan.yml
name: testtest
on:
  pull_request:
  push:
jobs:
  (snip)
% ./test-act -W testdata pull_request

Could I get the steps to reproduce?

[alfredodeza]

@lufia I'm not sure why I'm seeing @main work now. I created a new branch, pushed it, and now it fails as before.

Here is the yaml to reproduce:

name: "Reproduce issue 433"

on: [push]

jobs:
  image:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2

    - uses: anchore/scan-action@act-fails
      with:
        image: "python:3.8"
        debug: true

Save that as workflows/reproduce.yaml and then run with act:

$  act -j image -W workflows

@alfredodeza Thank you, I understand the problem. Act should checkout refs/remotes/origin/act-fails instead of refs/heads/act-fails.

I will create a new pull request.
