GitKraken Pre-receive Hook Denied

GitKraken is a popular Git client that provides an easy-to-use interface for developers to work with Git repositories. One of the features it offers is the ability to configure pre-receive hooks on a repository. These hooks are scripts that run before any changes are accepted into the repository, allowing you to perform custom validation or enforcement rules.

Shell-Bash

Pre-receive hooks in GitKraken are written in Shell-Bash, a widely-used scripting language for Unix-based systems. Shell-Bash provides a powerful set of tools and utilities that make it easy to automate tasks and manipulate data.

Hook Denial

The specific error message you encountered, "pre-receive hook denied," suggests that the script you have configured in GitKraken's pre-receive hook has rejected the changes you attempted to push to the repository. This rejection may be due to a variety of reasons, such as failing custom validation rules or not meeting certain criteria required by the hook.

Best Practices

When writing a pre-receive hook, it is essential to consider the specific requirements and constraints of your project. Here are some best practices to follow:

1. Validate Code: Check for any coding standards or policy violations and reject changes that do not comply.
2. Enforce Branch Naming: Ensure that branch names follow a standardized naming convention to maintain consistency.
3. Prevent Sensitive Data: Scan for confidential information like access tokens, passwords, or other sensitive data before accepting changes.
4. Check Commit Messages: Verify that commit messages have a certain format or contain specific keywords to improve communication and tracking.
5. Verify Author Identity: Validate the user's identity before allowing changes to be committed to prevent unauthorized access.

Example Pre-receive Hook

#!/bin/bash

# Reject any commits with empty commit messages
while IFS= read -r oldrev newrev refname; do
    for commit in $(git rev-list "$oldrev..$newrev"); do
        message=$(git show --no-patch --format=%B "$commit")
        if [[ -z "$message" ]]; then
            echo "Empty commit message detected in commit $commit. Rejecting push." >&2
            exit 1
        fi
    done
done

# Accept the push if no issues were found
exit 0

The example above demonstrates a simple pre-receive hook that rejects any commits with empty commit messages. It iterates over each new commit in the push range and checks if the commit's message is empty. If an empty commit message is found, the hook prints an error message and exits with a non-zero status code, which causes the push to be rejected.

Remember, you can customize this script according to your project's requirements and add more validation rules or enforcement mechanisms as needed.
