### Another bzr2git example

Today, I tried to switch one of my personal repositories for debian-related scripts from bzr to git, just like I've done for pmount. The trick was that this time, I wanted to only move a part of the repository, not the full repository. I had only been working before with CVS and SVN who have the idea of modules, which is not the case for bzr or git. So I made the mistake of using a single bzr for several projects, which I realize now is not a very good idea...

In any case, I managed to drop some parts and here is how I did it; the trick was precisely to use SVN as an intermediate storage medium, using the following configurations files. First, bzr2svn.conf

[DEFAULT]
verbose = True
patch-name-format = ""

[project]
source = bzr:source
target = svn:target
start-revision = INITIAL
state-file = tailor.state

[bzr:source]
repository = /home/vincent/debian-devel/bzr/scripts

[svn:target]
repository = file:///tmp/testtai
module = biniou


and svn2git.conf:

[DEFAULT]
verbose = True
patch-name-format = ""

[project]
source = svn:source
target = git:target
start-revision = INITIAL
state-file = tailor.state

[svn:source]
repository = file:///tmp/testtai

[git:target]
git-command=/usr/bin/git


Then, all that is left to do is to run tailor on the resulting configuration files:

~ tailor -D -c bzr2svn.conf
~ tailor -D -c svn2git.conf

once in git, you can also split repositories by directories and much more using "git filter-branch"

Thanks, I wasn't aware of that ! (I'm still rather new to the amazing possibilities of git...).
