Options for the replacement of CVS

• CVS has a limited authentication model that means we need to fudge permissions every time a file is updated.

• Symlinks are not supported

• CVS is centralised which means that people need to be logged into the cvs pserver in order to use it
  • A decentralised repository would reduce the need for branching when commiting medium sized changesets.
  • A decentralised repository would mean that people don't have to be logged in to change the code, although they would not then benefit from the public_html facility.

bzr

Bazzar-ng will be released with etch and is a candidate that fixes all the above shortcommings

• Has native windows support
• Support for directory renames
• Has mode that mimicks cvs
• Fairly extensive documentation
• Lots of plugins
• Not quite so fast, but newer versions are better

git

Git will be released with etch and is a candidate that fixes all the above shortcommings

• Renames are guessed based on the contents of a file as opposed to svn & bzr which use unique-ids
• Strong support for non-linear development (branching).
• Fast
• Limited documentation
• Rapidly moving target (etch will soon be out of date).

svn

SVN is the usual drop-in replacement for CVS.

• SVN fixes most of the CVS shortcommings
• SVN is very similar in operation to CVS
• SVN uses a centralised repository
• Very popular alternative to cvs
• Stable
