Bazaar support for Subversion branches, working trees and repositories


bzr-svn is a plugin that allows Bazaar direct access to Subversion repositories. It allows most bzr commands to work directly against Subversion repositories, as if you were using bzr with a native bzr repository.

The plugin can at the moment be used to commit to, pull from, merge from, push to and view logs of Subversion branches from Bazaar.


The following features are currently present:

  • Connecting to remote Subversion repositories over all protocols supported by Subversion itself (at present: svn://, svn+ssh://, http:// (webdav), file://) as well as dump files.

    Checkouts, lightweight checkouts and branching works.

  • Integrates well with Bazaar.

  • Track Bazaar merges in Subversion. Merged revisions show up as ghosts.

  • Subversion working copies. Can be modified, queried (bzr status on a svn- native working copy created with svn co works) and committed from.

  • Committing to Subversion from Bazaar.

  • Push Bazaar revisions to Subversion.

  • Follow branch copies. Revision history is not truncated when a branch was copied in Subversion.

  • Efficiently uses network bandwidth.

  • Recognizes file metadata (executable bits, symbolic links).

  • 'svn-import' command with functionality similar to svn2bzr.

  • Ability to track merges done with SVK and write merges from SVK/Subversion branches in a format understandable by SVK.
  • Generates consistent file ids and revision ids. Two branches made using this plugin of the same Subversion branch will result in exactly the same Bazaar branch.
  • Handles complex operations in Subversion: committing to two branches at once, upgrading directories to branches, copies from early revisions, ...
  • Tested on Linux, Windows and Mac OS X.


bzr-svn can be used through the regular Bazaar user interface, see the Bazaar Documentation Overview for documentation on that.

Some bzr-svn specific issues are answered by the FAQ.

The way Bazaar metadata is stored in Subversion and the other way around is specified in the mapping specification.


Please use the regular Bazaar channels for support for questions about bzr-svn.


Unsupported Subversion File Properties

Some Subversion properties can currently not be represented in Bazaar and are therefore ignored for the time being:

  • 'svn:ignore' is not imported. There should be a Repository.get_ignores(revid) call in Bazaar rather than a magic '.bzrignore' file. Spec at
  • 'svn:mime-type'
  • 'svn:eol-style'. Requires eol support in Bazaar.
  • 'svn:keywords'. Requires keywords support in Bazaar. Spec at #81463

Other features currently held back by Bazaars feature set:

You will need a recent version of Bazaar, usually the release of Bazaar released in the same month as the release of bzr-svn you are using. bzr-svn will warn if the Bazaar release used is too old or too new.


If you are using Python 2.4, you will need to have the pysqlite module installed. Python 2.5 and higher have sqlite support built in.

Subversion development files

You need the Subversion libraries, including the development files. This should be readily packaged for most platforms. The package name for Debian and Debian-based distributions such as Ubuntu is libsvn-dev.


In order to be able to use the svn-upgrade command (for those who used versions of bzr-svn older than 0.4.0), you will need the bzr-rebase plugin.


!/ Please note that these instructions are only current for bzr-svn 0.4.11 and up.

Simply place this directory in ~/.bazaar/plugins and you should be able to check out branches from Subversion using bzr. Make sure the directory name is 'svn'. The plugin has to be built as well by running make.


Instead of installing the plugin yourself, you can also install a prepackaged version of it for your platform.

Windows Setup

An unofficial bzr-svn installer for Win32 as well as an unofficial, patched build of Python-Subversion for Windows can be found at This package can be used with the Python-based installer or the standalone installation of Bazaar.

Debian/Ubuntu GNU/Linux

Debian/Ubuntu packages are available from Jelmer's Debian repository.

Ubuntu's in-development release and Debian sid usually also contain the latest release.


GoboLinux includes a recipe for bzr-svn.

OpenSuse Linux

OpenSuse packages created by Michael Wolf are available from

Gentoo Linux

An unofficial Gentoo overlay containing the patches for Subversion versions 1.3 and 1.4, plus a bzr-svn ebuild are hosted on launchpad at

Mac OS X

Download the latest Subversion DMG from:

bzr-svn DMG packages can be found in bzr-svn launchpad page.

bzr-svn is now also available in MacPorts, and can be installed with: $ sudo port install bzr-svn


Please file bug reports in launchpad. The product URL for bzr-svn is



Unit testing

To run the bzr-svn testsuite, simply run 'bzr selftest svn'
