Now I'm offended. Subversion developers are very well aware of the
issues with the working copy library. Nobody is telling us there is no
problem, however, for smaller working copies and subtrees of large
ones, the problems are tolerable.
We have been working on fixing the performance issues within the
existing library, as well as correctness issues. Moreover, we have
been implementing merge tracking and other very strongly demanded
(required) features.
And where were you all those years? Since you have customers using
Subversion, you presumably have income off Subversion, what have you
contributed in terms of development or design effort? Or any other
effort which could have resolved the issue, for that matter?

Now come on... We're very strict in our quality levels is what would
have been more approprate for you to say. Ofcourse that comes at a
time cost; cost/quality will remain a trade-off, one I hope we will
keep making in favor of quality for a long time to come!

And what will you do to make sure it does?

I'm against that. And I hope all other devs are too: Bert (not Burt)
has indicated that patch can't be used in production. Don't be
tempted to do so. You'll learn to appreciate our efforts to achieve
the quality standards that we do, if you use it. As Bert says: It will
eat your production working copies for sure.
Bye,
Erik.
