pre-commit Error missing config value GIT_CONFIG_VALUE_0

Question

When i commit changes via Github Desktop, pre-commit cannot handle the changes and commit them but overwrites all other stages changes (the once i didn't intent to commit now) by its improvements.

This appears since during a commit in Github Desktop to my local branch, Avast free antivirus interrupted the process to check some file for virus. Since i didn't want Avast to interrupt it i canceled the scan, probably making things worse.

Now i get the following message when i'm trying to commit:error message

I tried already to use

• git reset, git update-indes,
• delete the repo and set it up new
• use pre-commit uninstall and install
• use pre-commit run --all-files

On another machine, the same repo runs smoothly. Does anyone has an idea what and how i have to reset to solve this issue?

Here is the pre-commit log:

I cannot solve your problem but let's me try to point you to this direction: GIT_CONFIG_* env vars. Do you have ``GIT_CONFIG_COUNT` env var? – Tearjerker

Having the same issue! Committing through VS Code and command line has no problem, so it seems to be specific to GitHub Desktop. Likewise, GitHub Desktop had an update recently. I wonder if that affected this. In particular, the pre-commit that is failing for me is check-added-large-files. trim-trailing-whitespace passed before failing on large files. – Thionic

@ramon would you be willing to open up an issue on the GitHub Desktop repo? github.com/desktop/desktop/issues/… – Thionic

I commented out check-added-large-files and now it errors on check-merge-conflicts after passing python-ast and json. EDIT: xref: github.com/pre-commit/pre-commit/issues/3245 – Thionic

Answer 1

There's a temporary fix/workaround for this.

0. Exit GitHub Desktop.
1. Go to your GitHub Desktop resource app folder. It should be listed in the error you receive, in your case C:\\Users\\UsrName\\AppData\\Local\\GitHubDesktop\\app-3.4.2\\resources\\app. In my case I'm on version 3.4.3 now, so I would choose whatever is newest.
2. Open the renderer.js file in a text editor
3. Search for "GIT_CONFIG_VALUE_0":"" in the file
4. Change it to "GIT_CONFIG_VALUE_0":null. (some people have reported setting the value to 0 or "*" and it also working)
5. Restart GitHub Desktop
6. I assume we'll need to re-apply this fix every time the version updates.

Fix found in this thread - https://github.com/desktop/desktop/issues/18945. Unfortunately they closed the issue. If you'd like to ask for them to investigate a long-term fix on that issue maybe we can get movement.

Workaround from GitHub issue comment. Run this and reopen Github Desktop.

import os

file = r'%LOCALAPPDATA%\GitHubDesktop\app-3.4.3\resources\app\renderer.js'
file = os.path.expandvars(file)
find = 'GIT_CONFIG_VALUE_0:""'
replace = 'GIT_CONFIG_VALUE_0:"null"'
with open(file, 'r') as f:
    content = f.read()
    content = content.replace(find, replace)
with open(file, 'w') as f:
    f.write(content)
