dreamweaver + subversion + webdav
Hello, all. I am trying to use Subversion with Apache 2.1 (using
mod_dav_svn + mod_dav + mod_dav_lock) as a repository, to which I want
to connect Dreamweaver. Everything works fine, except that I cannot
create new files. I read a thread related to this problem that was
dated last March, but I never saw a definitive conclusion.
So, before I start sending lots of detailed debugging information, I
thought I'd ask: is this a known problem, and if so, is there a
solution?
thanks.

Subversion 1.0 is not a generic WebDAV server, nor was it ever
advertised as such. There's no other "better" way than what you're
already doing. :-)
We chose WebDAV because (1) http goes through firewalls, (2) apache is
already an excellent generic server, (3) potential for http proxies and
caching, and (4) future DAV compatibility potential.
The key in point #4 is the word "potential". Subversion 1.0 has *some*
compatibility with other DAV clients, but not complete. Appendix D in
the book talks all about that, as I'm sure you're aware. But the main
point is that we didn't choose WebDAV so that Subversion can seemlessly
interact with Dreamweaver, Adobe, MSOffice, etc. If you can make it
work, that's great, more power to ya. Otherwise, real compatibility is
a far-future feature. Autoversioning was a cute freebie I threw into
the code over an xmas holiday, just a small step on the road to real
interoperablity. That's why I mentioned that anyone using
Autoversioning is exploring 'uncharted territory'.

Looks like Dreamweaver is attempting to LOCK a non-existent URL. This
is a technique (described by the DAV spec) for reserving a filename
before you PUT to it. I don't think all DAV servers support this
feature, though, I don't remember. You'll have to check the spec about
"locking null resources". Anyway, it looks like mod_dav (or
mod_dav_svn) isn't supporting that sort of request. Patches are
welcome. :-)

You say that few people are using autoversioning, less still with
mod_dav_lock -- is there a better, or more standard way to get
subversion working with other WebDAV clients? I am only going on what
documentation I can find, but I'm happy to try out other approaches.
Here are the log entries in the Apache access.log file that relate to
saving a new file (test.htm):
192.168.2.133 - webdav [11/Feb/2004:15:05:30 -0800] "PROPFIND
/svn/repo/test.htm HTTP/1.1" 404 315
192.168.2.133 - webdav [11/Feb/2004:15:05:30 -0800] "PROPFIND
/svn/repo/test.htm HTTP/1.1" 404 315
192.168.2.133 - webdav [11/Feb/2004:15:05:30 -0800] "LOCK
/svn/repo/test.htm HTTP/1.1" 405 339
And here is what Ethereal captured during this transaction:

Not many people use the autoversioning feature at all, and especially
not with apache 2.1's mod_dav_lock. It's uncharted territory. Every
webdav client seems to be temperamental in a different way.
The most useful thing is to show us the webdav HTTP dialogue that
happens when dreamweaver tries to create a new file (use ethereal to
capture that.)
