NAME
Git::Hooks::GerritChangeId - Git::Hooks plugin to insert a Change-Id in a commit message
VERSION
version 1.12.2
DESCRIPTION
This Git::Hooks plugin hooks itself to the commit-msg hook. It is a reimplementation of Gerrit's official commit-msg hook for inserting change-ids in git commit messages. It's does not produce the same Change-Id for the same message, but this is not really necessary, since it keeps existing Change-Id footers unmodified.
(What follows is a partial copy of that document's DESCRIPTION section.)
This plugin automatically inserts a globally unique Change-Id tag in the footer of a commit message. When present, Gerrit uses this tag to track commits across cherry-picks and rebases.
After the hook has been installed in the user's local Git repository for a project, the hook will modify a commit message such as:
Improve foo widget by attaching a bar.
We want a bar, because it improves the foo by providing more
wizbangery to the dowhatimeanery.
Signed-off-by: A. U. Thor <author@example.com>by inserting a new Change-Id: line in the footer:
Improve foo widget by attaching a bar.
We want a bar, because it improves the foo by providing more
wizbangery to the dowhatimeanery.
Change-Id: Ic8aaa0728a43936cd4c6e1ed590e01ba8f0fbf5b
Signed-off-by: A. U. Thor <author@example.com>The hook implementation is reasonably intelligent at inserting the Change-Id line before any Signed-off-by or Acked-by lines placed at the end of the commit message by the author, but if no such lines are present then it will just insert a blank line, and add the Change-Id at the bottom of the message.
If a Change-Id line is already present in the message footer, the script will do nothing, leaving the existing Change-Id unmodified. This permits amending an existing commit, or allows the user to insert the Change-Id manually after copying it from an existing change viewed on the web.
To enable the plugin you should add it to the githooks.plugin configuration option:
git config --add githooks.plugin GerritChangeIdNAME
Git::Hooks::GerritChangeId - Git::Hooks plugin to insert a Change-Id in a commit message.
CONFIGURATION
There's no configuration needed or provided.
EXPORTS
This module exports one routine that can be used directly without using all of Git::Hooks infrastructure.
rewrite_message GIT, MSGFILE
This is the routine used to implement the commit-msg hook. It needs a Git::More object and the name of a file containing the commit message.
