Pre-commit hook compatibility

[IdanAdar]

My company now requires the use of a detect-secrets tool and a pre-commit step. After following the instructions and attempting to push a commit, it failed with the following:

Commit failed - exit code 1 received, with output: '[WARNING] Unstaged files detected.

I don't know if the problem is on the GitHub Desktop 1.5.2 beta 0 side, the pre-commit side, the Git side or the Python side. Any clues to resolve this will be much appreciated.

Does a manual git commit in the command line (hit Ctrl+`) also produce the issue?

[IdanAdar]

No. When using git commit it worked.

@IdanAdar thanks for the report. I believe this is an issue with the embedded Git, and I suspect I need to patch it to address this properly.

What's happening is inside the git-sh-setup that your pre-commit hook is failing on this command:

# Source git-sh-i18n for gettext support.
. "$(git --exec-path)/git-sh-i18n"

That's because the output of git --exec-path isn't resolving correctly. I can verify this by running the command directly against that version of Git:

$ ./git --exec-path
//libexec/git-core

This works fine on the command line because Git is installed at a known location, but the embedded Git needs to be "aware" that it's embedded inside a .app (or in a version-specific path on Windows).

[IdanAdar]

Thanks @shiftkey. Hopefully it's an easy fix. I'd like to continue using the client and of course promote it internally...

[shiftkey]

@IdanAdar i'm going to move this into dugite-native which is the project that needs to address this issue (there's not much the app itself can do aside from update the package once it's been fixed).

[IdanAdar]

Thanks. Still hopeful for fast resolution.

Not sure how well it is going to work but I copied my git-secrets file and pasted into the "C:\Users\%username%\AppData\Local\GitHubDesktop\app-2.2.3\resources\app\git\usr\bin" it allowed me to commit like I did before installing git secrets I have not tested if it will prevent uploading secrets yet.

To expand on the above:

1. Copy the file 'git-secrets' into the bin folder.
2. Edit the new, copied file. Replace '#!/usr/bin/env bash' with '#!/bin/sh'
3. Repeat step 2 on any file in your repo's .git/hooks folder that isn't marked '.sample'.
