Benchmark (100 untouched projects): * GetUploadableBranches: 0.985s -> 0.0004s (2,200x faster) * repo upload (3,045 projects): saves ~2.5s of redundant ref scans During `repo upload`, `GetUploadableBranches()` currently scans `self._allrefs` across all projects in the workspace. In large manifests (e.g. Android with 3,000+ projects), `self._allrefs` executes `git for-each-ref`, `git symbolic-ref`, and full filesystem mtime traversals on thousands of projects where no local branch was ever started or modified. Any branch that can be uploaded for review must have upstream tracking configured via `[branch "..."]` sections in `.git/config` (otherwise `branch.LocalMerge` is None and `GetUploadableBranch` returns None). This patch introduces early-pruning fast paths: 1. When no branch subsections exist in `.git/config` (or only 2-part keys like `branch.autosetupmerge`), return [] immediately without touching `_allrefs`. 2. When a `selected_branch` is specified (e.g. `repo upload --br=...`), query `branch.LocalMerge`, `refs/heads/<branch>`, and `refs/published/<branch>` directly, skipping the whole-tree ref scan. 3. In `subcmds/upload.py`, optimize `_GetMergeBranch` to resolve the merge branch in-memory via `project.CurrentBranch` and `project.GetBranch()` instead of spawning two `GitCommand` processes.

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:
-
Copy or symlink
completion.zshto a file named_repoin 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/_repoThen add that directory to your
fpathin~/.zshrcbeforecompinit:fpath=(~/.zsh/completion $fpath) autoload -Uz compinit compinit -
Or source the file directly and call
compdefin your~/.zshrc:source /path/to/git-repo/completion.zsh compdef _repo repo
