They use a slightly different paradign: there's no "integrate" (my apologies if I got it wrong) operation on a file, only directories can be copied like this. Also, their metaphor of the "versioned file system" is something Perforce I believe doesn't articulate explicitly.4) inter-file branching with lazy copy mechanism: yes, one of the
centerpieces of the Subversion architecture
Hmm... where did they get that idea from? Immitation is the sincerest form of flattery I suppose.
Good for you. How many years have Perforce been in development compared to Subversion? Performance is not where it aches worst in Subversion today. Or do you think Source Mage is a project huge enough to require all that power? Surely, examples like GNOME, Apache, or NetBeans being maintained in CVS, tell us that it's _possible_ to use even such a "limited," compared to Perforce, system, for very large and convoluted projects.5) Scalability: look at the list of publis Subversion repositories
http://subversion.tigris.org/svn-repositories.html, the largest there is
5 GB (Subversion is slower than CVS as many observed -- no comparison
with Perforce had been made -- but they're working on this)
FWIW Perforce is *much* faster than CVS for the majority of actions and is just plain faster for the rest. There are some performance figures here http://www.perforce.com/perforce/reviews.html for those that are interested. And these benchmarks are entirely fair and reproducible - not Mindcraft-style! The links to the docs on the hardware and test procedures are on the page above.
Nowhere I said Perforce is a bad product or a bad player as a company. It actually compares very favorably to many SCM systems, and the company policies and development directions look very good, if a bit too modest for your feature set and capabilities (with addition of distributed versioning, you could compete very easily with Rational tools I think, and Rational has a bad reputation in UNIX world which you could use to your advantage). At the same time, I guess I don't have to explain you why CVS, Subversion, and maybe BitKeeper, will continuously outrun Perforce in the number of open source and free software projects maintained using these SCMs. Also, don't forget the ratio of community developers to the developers hired to produce Perforce. It's not a war, it's survival of the fittest.
Tony.
