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.

It also provides a Bazaar subcommand ("bzr svn-import") for converting
complete Subversion repositories to Bazaar repositories.


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.

- 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_.

.. _svn2bzr:

- Ability to track merges done with SVK_ and write merges from SVK/Subversion
  branches in a format understandable by SVK.

.. _SVK:

- Writes svn:mergeinfo property used by Subversion 1.5.

- 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`_ and the `Bazaar User Guide`_ for documentation on that.

Some bzr-svn specific issues are answered by the FAQ included with 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:

- 'svn:externals'. Externals should be mapped to Bazaar 'by-reference'
  nested branches and the other way around. This can't be implemented
  until Bazaars nested branch support lands. The current work-in-progress also
  needs support for pointing at the tip of a branch rather than at a
  specific revision.

- Tracking copies.
  . Spec at

- Showing SVN merges as merges in Bazaar.
  . Requires support for cherry-picking. Spec at

Bazaar Commands

All Bazaar commands should work fine with Subversion branches or should properly inform you that they do not. If you find any commands that don't work, please file a bug.


* `1.0.4`_ (works with Bazaar 2.2)
* `1.0.3`_ (works with Bazaar 2.2)
* `1.0.2`_ (works with Bazaar 2.0, 2.1)

`all releases`_

.. _all releases:
.. _1.0.4:
.. _1.0.3:
.. _1.0.2:
.. _1.0.1:



You will need a recent version of Bazaar. bzr-svn
will warn if the Bazaar release used is too old or too new.


You need the `Subvertpy`_ Python module, which provides Python bindings
for the Subversion library.

.. _Subvertpy:


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``.:w


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

Windows Setup
The standard `Windows installers for Bazaar`_ include bzr-svn.

.. _Windows installers for Bazaar:

Debian/Ubuntu GNU/Linux
Debian/Ubuntu packages are available from Debian experimental/sid and the Bazaar PPA.

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

Debian's main repositories also have bzr-svn since at least the lenny release.

OpenSuse Linux
OpenSuse packages created by Michael Wolf are available from

Gentoo Linux
An unofficial Gentoo overlay containing a bzr-svn ebuild are hosted on launchpad at

Mac OS X

bzr-svn is included in the MacOSXBundle_.

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



* lp:bzr-svn (current release series)

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


If you used ancient versions of bzr-svn that used a different mapping mechanism (< 0.4) you may want to use the ``rebase-foreign`` command that is available in the `bzr-rewrite`_ plugin.

.. _bzr-rewrite:

bzr-svn was written by JelmerVernooij_ with the help from various other people. See the AUTHORS file in the source distribution for a list.

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.
