On this page, we are trying to collect argument pro and contra both staying with CVS, and switching to SVN. Behind each "argument" is a list of people who agree that this particular argument is valid. We currently have no other realistic choices (since SF.net offers us exactly those two), so I am not comparing more systems here.
Pro Subversion
- Support for versioned renames/moves (impossible with CVS): Fingolfin, Ender
- Supports directories natively: It's possible to remove them, and they are versioned: Fingolfin, Ender
- File properties are versioned; no more "executable bit" hell: Fingolfin
- Overall revision number makes build versioning and regression testing much easier: Ender, Fingolfin
- Atomic commits: Fingolfin
- Intuitive (directory-based) branching and tagging: Fingolfin
- Easier hook scripts (pre/post commit, etc): SumthinWicked (I use it for Doxygen after commits)
- Prevents accidental committing of conflicted files: Salty-horse, Fingolfin
- Support for custom 'diff' command: Fingolfin
- Offline diffs, and they're instant: sev
Pro CVS
- Lots of people know how to use it: Fingolfin
- Lots of documentation available: Fingolfin
Contra Subversion
- Takes up twice as much disk space: Fingolfin
- We need to put efforts into transferring repository to it: sev
- Strictly spoken, the conversion is easy (it's a one-button click in the admin panel of SF.net), we only make it hard by our wish to manually fix problems in the existing CVS repository (says Fingolfin)
Contra CVS
- No support for versioned renames/moves (CVS repos hackery is not even remotely a replacement): Fingolfin
- No proper support for directories (in particular, deleting them, but also renames/moves): Fingolfin
- I want to stress that it was a major hassle in history of our project: sev
