Python script for pre-receive hook to limit the commit size for git repositories

git_commit_limit_size

Overview

This is a Python script for pre-receive hook to limit the commit size for git repositories. It can set the following limits:

• Limit the maximum size of any individual file
• Limit the total size of all files being committed
• Limit the number of files being committed

The script is designed as a hook that runs on many repos, for installations such as GitLab. Limits are set in a configuration file, using Python 3 regular expressions against which the repository name is matched. Each line specifies all three limits for a particular regular expression, with 0 for a specific limit meaning "no limit". Limits are set by the first line with a matching regular expression. It is recommended that the last line contain the regular expression .*, which matches all repositories.

Contents

• limit_size.py: pre-receive hook to limit the size of files and entire git repostories
• limit_size.conf: sample configuration file for limit_size.py

Requirements

There are no requirements for installation beyond Python 3 and git.

git_commit_limit_size's Issues

Error when deleting upstream branch without permissions

I was trying to delete a remote branch which I do not have the permissions to modify. Instead of giving me a permission error it gives me the following.
