Tools for working with Git at Mozilla.

In order to set this up, clone this repository somewhere, run the git submodule init and then git submodule update command, and add your clone to $PATH.

Many of these tools rely on a notion of your current branch's "upstream branch". For example, git push-to-try pushes to try all patches in your current branch that aren't upstream. See the git-tracks section below for details on how to change your upstream branch.


Push commits from git to bugzilla. For example, to push the two top commits in your repository, run

git bz attach -e HEAD^^..

(This will complain if your commits don't mention the same bug number in their summaries.)

If a commit's message starts with "FOLD", it will be folded into the previous commit before pushing to bugzilla.

(Actually, git-bz can do more than push commits from git to bugzilla. But I don't use it for anything else, so I'm not sure which of the other features work with


Create a new working directory based off an existing local git repository.


Gets the name of the current branch's upstream branch. With -d or --default, git-tracks outputs "origin/master" if there's no upstream branch.

You can set this with git branch --set-upstream CURRENT_BRANCH UPSTREAM_BRANCH. (Don't do git branch --set-upstream BRANCH; that won't work right!)

Many other tools in this package use git tracks -d as your branch's "upstream branch".


Find the hg commit corresponding to a git commit.


Usage: git push-to-hg [-t/--tip] PATH_TO_HG_REPO [GIT_REVS]

Push commits from git to a new qqueue in an hg repository. If GIT_REVS is omitted, push the commits $(git merge-base HEAD $(git-tracks))..HEAD (i.e. everything in the current branch that's not upstream).

If -t or --tip is specified, pull and update the hg repository to latest tip before pushing. Otherwise, update the hg repository to the revision atop which the git commits are based.


Usage: git push-to-try [-t/--tip] PATH_TO_HG_REPO TRYCHOOSER_PARAMS

Push the commits $(git merge-base HEAD $(git-tracks))..HEAD (i.e. everything in the current branch that's not upstream) to try, by way of the given hg repository.

TRYCHOOSER_PARAMS should be, e.g. -b do -p all -u all -t none.


Usage: git push-to-trychooser [-t/--tip] PATH_TO_HG_REPO [GIT_REVS]

The same as git push-to-hg, but also runs the interactive trychooser command before pushing the commits to try from the given hg repository.


Outputs the last common revision of the current branch and upstream. (This command is a synonym for git merge-base HEAD $(git-tracks).)


An alias for git rebase -i $(git qparent). This lets you interactively rebase your current branch without moving the commits to a new upstream base.


Open all the files modified in the specified rev range in your $EDITOR. (If no rev range is specified, open the files modified in your current checkout.)


Eliminate any trailing whitespace from your uncommitted changes.

Note that this will reset your index; that is, any changes you've git add'ed will need to be added again. But it won't (or at least, shouldn't!) erase any changes.


Like hg qapplied, output the commits in this branch which are not upstream.


Format a patch from git format-patch as an hg patch.


Output the name of the active git branch, but if there's no git repository below the cwd, output nothing. This is useful when you want to display the current branch name on the command line.

For example, I have in my ~/.bashrc:

function vcs-branchname() {
  git_branch=`git branchname`
  if [[ "$git_branch" != "" ]]; then
    echo " ($git_branch)"

PS1='\[\033[01;$PROMPT_COLOR\]\u@\h\[\033[00m\]:\[\033[01;$PROMPT_COLOR\]\w\[\033[00m\]$BRANCH_NAME\$ '

which makes my prompt look like

jlebar@hostname:~/current/path (name-of-git-branch)$


A pre-commit hook which checks for .orig files and trailing whitespace.

To install this hook, symlink it into your repository's .git/hooks directory (with the name pre-commit).
