How can I mirror a project hosted on launchpad on github?

Question

I want to contribute actively to a project that is hosted on Launchpad. I'm much more comfortable with GitHub, and would like to continue to use it if possible. Would I be able to mirror the bzr repository on github?

If it's possible, how could I set this up?

Answer 1

You could try some kind of git-bzr bridge like this git-bzr git-bzr script:

This script allows you to add bazaar repositories as git branches in your git repository.
After that, you can fetch the Bazaar repo, make some changes, and push it back into Bazaar.

The reverse is possible, meaning you can clone a bzr repo and push to your GitHub repo with bzr-git.

That one worked well. I ended up using a bash fork of the project, to remove the ruby dependency. Thanks a lot. – Teter

for a more up to date project for git-bzr stuff go github.com/termie/git-bzr-ng – Gape

@Globalkeith thank you. I have edited the answer to point to that version. – Stank

Beware: trunk bzr-fastimport is broken and may corrupt your 'marks' file..

I have just written a detailed how-to for mirroring a Launchpad Bazaar repo to Github (note that it focuses on Mac users).

A minimal version of this how-to:

1. Install bazaar and a plugin to make it work with git

brew install bazaar
brew tap gdubicki/tap
brew install gdubicki/tap/bzr-git

2. Clone the Bazaar repository

# for example:
bzr branch lp:update-motd

3. Create the Git repository

You’ll need is the URL to the repo, in my case:

git+ssh://[email protected]/gdubicki/update-motd-for-non-ubuntu.git

4. Push the clone to the remote

cd update-motd # or whatever is the name of the Bazaar branch
PYTHONPATH="/usr/local/lib/python2.7/site-packages" bzr dpush -v git+ssh://[email protected]/gdubicki/update-motd-for-non-ubuntu.git,branch=master
