Converting a Subversion repository to Bazaar

May 18, 2007 General Comments Off

I recently wanted to test drive Bazaar with a fairly large project.
The first problem is to convert the whole repository which happen to be stored in subversion to a bunch of Bazaar branches.
There’s a tool called svn2bzr written by Gustavo Niemeyer which allows you to easily import a bunch of subversion branches in bzr.

There’s nothing special about my subversion repository, it only contains a couple of modules in the same repository, similar to how KDE has it set up, but different to GNOME.

First you need a dump, that’s easily created using

$ svnadmin dump /path/to/url > stoq-projects.dump

Next step is to convert the four modules called kiwi, stoqlib, stoqdrivers and stoq, to do that, issue this command:

$ python ./svn2bzr.py --scheme=trunk \
--exclude=kiwi(|/tags|/branches)$ \
--exclude=stoq(|/tags|/branches)$ \
--exclude=stoqdrivers(|/tags|/branches)$ \
--exclude=stoqlib(|/tags|/branches)$ ../stoq-projects.svndump stoq-projects

It turned out that the revision timestamp conversion had a couple of bugs, so you’d really need the latest version, incidentally available as a bzr branch from here.

Getting somewhere….

May 7, 2007 GNOME, PyGTK, Python 2 Comments

I’m very pleased to see that no less than 8 posts on Gnome are about PyGTK or applications using PyGTK. And does not count OLPC, which is also using it.

Very few of the posts are explicitly mentioning Python or PyGTK, it’s such a well accepted platform that there’s really no need to.

This the result of many years of hard work. I’d like to acknowledge the following people who have made it possible:

Gnome hackers, keep on being productive, use high level languages, spread the word and don’t forget to let us know what you’!
