Sylvain e9cb391117 project: Optimise GetCommitRevisionId when revisionId is set
When comparing 2 manifests, most of the time is
spent getting the relevant commit id as it relies
on _allrefs which ends up loading all git references.

However, the value from `revisionIs` (when it is valid)
could be used directly leading to a huge performance improvement
(from 180+ seconds to less than 0.01 sec which is more
than 25000 times faster for manifests with 700+ projects).

Bug: 295282548

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
