hg-git and pushing to git from mercurial

FEBRUARY 12, 2011

Documenting my experience pushing mercurial repos to git (and github specifically).

Install hg-git

Follow https://bitbucket.org/durin42/hg-git/src/tip/README.md

Install dulwich >= 0.6. On ubuntu:

sudo apt-get install python-dulwich

Get the latest version of hg-git:

hg clone https://bitbucket.org/durin42/hg-git

Add it to your extensions

git = path/to/hg-git/hggit

Push an existing mercurial repo

Assuming you’ve got a git repo somewhere, e.g. for me (rgrp) on github:

 cd my-current-mercurial-repo
 hg push git+ssh://[email protected]/rgrp/myrepo

Really important note: do not change git before the @ sign to your username as you would in mercurial but leave it as ‘git’ (this cost me around 20m of googling with errors like

Permission denied (publickey).
abort: the remote end hung up unexpectedly

You may also want to check your ssh setup with github really is working (see http://help.github.com/troubleshooting-ssh/).
