Pull Request Overview

This PR fixes the handling of cases where the uname command (used to detect Cygwin Git) is not an executable file and adds unit tests for verifying the behavior of is_cygwin_git. It also includes an update to the AUTHORS file to add a new contributor.

• Updated test_util.py to add tests for is_cygwin_git.
• Revised git/util.py to check if uname_cmd is an executable file before invoking it.
• Updated AUTHORS list.

As argued in#2027 (comment), I think we should actually mergecffa264 -- that is, this PR as it was before the change to usingstrings -- before proceeding with further changes. I think that could be done at any time. I suggest rewinding this PR to that point (you can preserve the extra commits on their own separate branch of course).

There are some minor refinements that could be included with that, but they can just as easily be done afterwards (for example, I can make a small PR later that includes them), so they're not blocking. I've included review comments below showing them as suggested-change diffs.

In addition to the reasons given in#2027 (comment) for starting that way, I also think it matches the scope you may have intended for this PR originally, based on the PR title.

This is not to say that the attempt to examine the contents of thegit executable file to discern if it is a Cygwin build should be discarded entirely -- only that I recommend integrating the working changes from before that, and then continuing with that subsequently. To that end, I've also included some review comments pertaining to those subsequent commits. To avoid confusion, I have refrained from including any suggested-change diffs in those.

...incidentally, is there a way for me to run the test pipeline locally without pushing my changes up first?

Yes, certainly. There are instructions in the readme, there istox.ini if you want to use thetox runner, and the commands in the CI workflows in.github/workflows can sometimes be useful. I'm also happy to help with any questions about setting that up or problems that arise with it (and please feel free to ping me about it). There is also software to attempt to run GitHub Actions workflows locally, such asact, though I have not tried that on this repository and I don't know how well it would work.

However, in order to run the Cygwin tests on your local machine--using any of those techniques or others--I think you would need to have a Windows system (or other system capable of running Windows programs) with Cygwin installed on it.
