Subversion migration

This page will outlined plans for migrating Biopython from CVS to Subversion (SVN), although in the end we switched straight to Git instead.

Biopython Users

Content for users to be created.

Installing Subversion

Microsoft Windows

Download and install either TortoiseSVN or RapidSVN. There is also a binary available for a command line based Subversion client; see the Subversion website.

Mac OS X

Download and install Subversion via Fink or the binary package.


Some distributions come with the Subversion packages by default, or they may have already been installed by your system administrator. Verify whether you have Subversion installed using which:

user@compy$ which svn

In the above example, Subversion is installed and its executable is located within /usr/bin/.

user@compy$ which svn

On the other hand, in the above example, which svn returns nothing. This indicates Subversion is not likely installed. You or your system administrator will need to use the appropriate package manager to download and install the packages for Subversion. For example, on Ubuntu, users would execute the following:

user@compy$ sudo apt-get update && sudo apt-get install subversion

Biopython Developers

Existing developer accounts should all continue to work as before. When working with the main trunk, basic operations such as checking out code, diff, and committing changes are very similar to those under CVS.

Biopython Migration Strategy

Currently this is being discussed on the Biopython developers mailing list, where there is a general consensus that moving to a distributed version control system (DVCS) would be more worthwhile than simple moving from CVS to SVN. See the GitMigragion page.
