Issue: actions/checkout doesn't copy git tracked but gitignored files

[jsoref]

The general behavior of .gitignore doesn't prevent files that are tracked from being checked out. It just prevents from from being updated or added.

I'd expect that act not copy over untracked files matched by .gitignore, but I'd expect it to include tracked files that are matched by .gitignore.

System information

• Operating System: Linux & macOS
• Architecture: x64
• Apple M1: no
• Docker version: on macOS: 20.10.8 (not sure about the version used by GHA)
• Docker image used in act: catthehacker/ubuntu:act-latest
• act version: 0.2.25

Expected behaviour

Files listed in .gitignore should be present in the checked out repository

Actual behaviour

Files listed in .gitignore are not present

Have you tried --use-gitignore=false?

[jsoref]

Yes, it would work, see the second commit/run.

But I shouldn't need to

[catthehacker]

Right, we can't change behaviour because it will break functionality for other people

[jsoref]

I see three possible behaviors:

1. Copy all files
2. Copy all files not matching .gitignore
3. Copy all files except non tracked files matched by .gitignore

The current default is 2. The flag gets 1. I'm looking for 3.

The distinction between 2 and 3 is imo a bug, hence this bug.
