project: initialize new manifests in temp dirs

If initializing the manifest fails for any reason, don't leave it in
a half complete state.  This can cause problems if/when the user tries
to reinit because different codepaths will be taken.  For example, if
we initialize manifests.git and don't finish probing the remote to see
what default branch it uses, we end up always using "master" even if
that isn't what the remote uses.

To avoid all of this, use .tmp dirs when initializing, and rename to
the final path only after we complete all the right steps.

We should roll this out to all projects we clone, but start with the
manifest project for now.

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
