status: Show ahead/behind info for local branches

When viewing `repo status`, it is difficult to distinguish between branches that have active unpushed changes and stale branches that are fully synced. Previously, developers had to run commands like `repo forall -c "git status"` to see their ahead/behind counts.

This change updates Project.PrintWorkTreeStatus to automatically calculate and display the number of commits a branch is ahead and/or behind its upstream tracking branch. We use `git rev-list --left-right --count` to fetch this information natively and efficiently.

If the branch is completely synced with upstream, no extra text is shown.

Added tests for ahead-only, behind-only, diverged, no-tracking, and fully-synced branch states.

repo

Repo is a tool built on top of Git. Repo helps manage many Git repositories, does the uploads to revision control systems, and automates parts of the development workflow. Repo is not meant to replace Git, only to make it easier to work with Git. The repo command is an executable Python script that you can put anywhere in your path.

Contact

Please use the repo-discuss mailing list or issue tracker for questions.

You can file a new bug report under the “repo” component.

Please do not e-mail individual developers for support. They do not have the bandwidth for it, and often times questions have already been asked on repo-discuss or bugs posted to the issue tracker. So please search those sites first.

Install

Many distros include repo, so you might be able to install from there.

# Debian/Ubuntu.
$ sudo apt-get install repo

# Gentoo.
$ sudo emerge dev-vcs/repo

You can install it manually as well as it's a single script.

$ mkdir -p ~/.bin
$ PATH="${HOME}/.bin:${PATH}"
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/.bin/repo
$ chmod a+rx ~/.bin/repo

Shell Completion

Repo includes completion scripts for Bash and Zsh.

Bash

To enable completion in Bash, source completion.bash in your ~/.bashrc:

source /path/to/git-repo/completion.bash

Zsh

To enable completion in Zsh, you can either:

  1. Copy or symlink completion.zsh to a file named _repo in a directory in your $fpath:

    mkdir -p ~/.zsh/completion
# You can copy the file:
cp /path/to/git-repo/completion.zsh ~/.zsh/completion/_repo
# Or symlink it:
ln -s /path/to/git-repo/completion.zsh ~/.zsh/completion/_repo

    Then add that directory to your fpath in ~/.zshrc before compinit:

    fpath=(~/.zsh/completion $fpath)
autoload -Uz compinit
compinit

  2. Or source the file directly and call compdef in your ~/.zshrc:

    source /path/to/git-repo/completion.zsh
compdef _repo repo
