Subversion is a version control system. You probably know it well as
it is the version control system employed by the Apache Software
The Subversion project would like to join the Apache Software
Foundation to remove the overhead of having to run its own
corporation. The Subversion project is already run quite like an
Apache project, and already counts a number of ASF Members amongst
Work on Subversion was originally started at CollabNet; Karl Fogel
was hired in January 2000. Jim Blandy, at RedHat, already had an
initial design for the storage system, which was incorporated into the
FS design. In February Brian Behlendorf invited Greg Stein to
contribute his WebDAV experience to Subversion. Ben Colins-Sussman
was hired in April 2000 to work on the project. In that same month
the first "all hands" meeting was held, where a number of "interested
people" came together to talk about the project.
Subversion was run as an open source project since the early days.
Now, more than nine years later, it retains a healthy community,
and has a good number of committers. In the life span of Subversion,
several committers have switched employers and have maintained involvement.
The committership is diverse, both geographically as well as in terms of
The equivalent of the PMC consists of all the full committers to the
Subversion project (currently around 55 people). The community uses the
voting process also used at the ASF. Releases are signed off by gathering
votes/digital signatures of each committer who verified the release
We feel the ASF and Subversion communities are very compatible,
witness the cross interest that already exists. There is both a
vibrant developer as well as a large and active user community.
Technology-wise, Subversion builds on APR, and implements two Apache
HTTP Server modules.
Note that Subversion has a number of related projects, which are not
part of this proposal (e.g. cvs2svn, TortoiseSVN, Subclipse).
More information on Subversion can be found at
http://www.subversion.org/ and http://subversion.tigris.org/.
The Subversion Corporation has a license to all source code, and has
CLAs on file for nearly all it's committers. That is, we have all but
one or two full committers, and some percentage of partial committers.
We have a number of *user-configurable* dependencies which are not
compatible with the AL:
- Neon, a HTTP client library, used by libsvn_ra_neon, is LGPL.
(An alternative HTTP client library, libsvn_ra_serf uses the Serf
library under ALv2.)
- Qt, KDE and GNOME libraries are also under LGPL-2.1. D-Bus (which
is also used by libsvn_auth_gnome_keyring and libsvn_auth_kwallet) is
under Academic Free License 2.1 or >=GPL-2.
(This support is for integration for KDE and GNOME's authentication
(This library provides translation support for systems without
a proper internationalization library.)
(This is used by the libsvn_fs_base system which stores its data
in BDB; an alternative repository system called fs_fs does not
have this dependency.)

- We will work with the Infrastructure team to transfer the subscriber
listings to the new destinations.
- We have not made a decision whether we prefer Subversion should be
imported into the main ASF Subversion repository or be hosted as a
separate repository to enable early testing of the repository code. We
intend to discuss this during the Incubation process before the code is
imported. It is also understood that ASF infrastructure team may be
willing to run custom pre-release Subversion server builds for the
entire ASF, so this separate repository option may not be required.

- We haven't made a decision between JIRA or Bugzilla at this time and
expect this decision to be made as part of the Incubation process. Our
current issue tracking system uses Issuezilla (a fork of Bugzilla) and
we have not yet decided whether we want to import our previous issues
into the new system and will decide this in the course of the Incubation

for automated builds and testing. Over time, we would like to migrate
these services to Apache infrastructure where appropriate.

not an intermediary while going through incubation. The cost of
switching twice would otherwise be significant due to the size of the
