status: improve parallel execution stability

The status command runs a bunch of jobs in parallel, and each one
is responsible for writing to stdout directly.  When running many
noisy jobs in parallel, output can get intermingled.  Pass down a
StringIO buffer for writing to so we can return the entire output
as a string so the main job can handle displaying it.  This fixes
interleaved output as well as making the output stable: we always
display results in the same project order now.  By switching from
map to imap, this ends up not really adding any overhead.

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
