[James Caple]

Hi,

The commentary on subversion caught my attention.  As an engineer who has worked with administering subversion to a certain degree over the last six months or so, I am actually glad to hear another development shop lament subversion database corruption.  It is true - once the berkley db gets corrupted, you pretty much have to rebuild your repository (and getting rid of all those recursive .svn directories can be a pain).  

Here's a great UNIX command for this:

find . -name .svn -exec rm {} \;

I have learned and experienced, however, that running subversion as a file managed repository instead of using berkeley db is MUCH more reliable (assuming that's not how you guys are using subversion already).  I have also had problems using Apache HTTP access to subversion using berkley db.  Using the file system and the subversion svn daemon, I have had much better success with the tool.

Never used perforce, but subversion has grown on me.

2 cents,

James

interested in contributing to Laszlo until we compile to something that runs
in an open source container like DHTML or a SVG player.  I doubt we'd have many
of these folks working on Laszlo contributions.

Switching from Subversion to P4, given that the license is free, won't be too
difficult for folks to manage.  I personally use Perforce for work and svn for
small home projects without any problems.
