info: Parallelize project data gathering for JSON output

https://gerrit-review.googlesource.com/c/git-repo/+/581921 parallelized
`repo info` for text output. This commit does the same for JSON output
format.

Benchmarked `repo info --format=json` on an Android workspace with ~3k
projects (N=3):
- Before (sequential): 1m 30s average
- After (parallelized): 46s average (~2x speedup)

Verified that the JSON output is identical before and after.

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
