Update 2010-01-23: Nowadays the plugin is packaged in Debian
bzr-fastimport) and Ubuntu (package
installed you can just go and use
bzr fast-export instead of the
alias. Thanks to the people that commented about this update :)
Those days I faced the need of moving a set of Bazaar branches into
a set of Git repository, and althought I already knew about
Tailor, but I wanted a one-shot conversion and Tailor is more, ahem,
tailored for periodic synchronization. So I decided to try git
fast-import, because I already knew about bzr fast-import plugin
which is inspired by the Git version of the thing. The Bazaar plugin
bzr-fast-export script which can be used to feed input data
First, we need to install the Bazaar plugin. This one is easy:
mkdir -p ~/.bazaar/plugins cd ~/.bazaar/plugins bzr get lp:bzr-fastimport fastimport
I will be importing three branches into a Git repository, so we need to create a Git repository:
mkdir ~/myproject.git cd ~/myproject.git git --bare init
I suppose you have three related Bazaar branches:
~/myprojectis the main branch of the project. It will be imported as
masterbranch in Git.
~/myproject.branch-bare two branched whose parent is the first one.
The, in a shell, do:
alias bzrexp="~/.bazaar/plugins/fastimport/exporters/bzr-fast-export" bzrexp --export-marks=../marks.bzr ../myproject \ | git fast-import --export-marks=../marks.git bzrexp --marks=../marks.bzr --git-branch=branch-a \ ../myproject.branch-a | git-fast-import \ --import-marks=../marks.git --export-marks=../marks.git bzrexp --marks=../marks.bzr --git-branch=branch-b \ ../myproject.branch-b | git-fast-import \ --import-marks=../marks.git --export-marks=../marks.git
Voilà! It will run in a snap, the limit will be your disk speed, as both the exporter and the importer are very fast.
