I already had a SVN project up and running at svn.mydomain.com/myproject (installed from the DH Panel) and could commit to it, checkout, browse, etc.
I then setup Trac via the DreamTracInstall script from the wiki and could use that to browse the source of my project repository. However, I could no longer browse Subversion directly. I modified the Rewrite rules in my .htaccess file so that requests to the Subversion project folder were no longer passed through Trac's index.fcgi and I could then browse the repository directly in my web browser again.
However, I still can't commit or browse the remote repository from my PC via the SVN command line utility or TortoiseSVN. Both complain about PROPFIND errors:
svn: PROPFIND request failed on '/'
svn: PROPFIND of '/': 200 Ok (http://svn.mydomain.com)
and my apache access.log is filled with:
111.222.333.444 - - [28/Sep/2007:07:53:38 -0700] "PROPFIND /myproject/trunk HTTP/1.1" 401 3547 "-" "SVN/1.4.5 (r25188) neon/0.26.3"
111.222.333.444 - - [28/Sep/2007:07:53:38 -0700] "PROPFIND /myproject HTTP/1.1" 401 3491 "-" "SVN/1.4.5 (r25188) neon/0.26.3"
111.222.333.444 - - [28/Sep/2007:07:53:39 -0700] "PROPFIND / HTTP/1.1" 200 6095"-" "SVN/1.4.5 (r25188) neon/0.26.3"
There is nothing in the error.log that relates to the requests.
I'm connected to the remote repository using a URL like http://svn.mydomain.com/myproject/trunk. Trac is installed at http://svn.mydomain.com/
Trac works fine and I can use it's built-in Browse functionality to view the repository files. And as I said above, I can again look at the latest changeset through subversion directly by going to http://svn.mydomain.com/myproject/, but trying to do anything against the repository remotely is failing.
The last thing I tried was adding another RewriteCond to the htaccess file that would ignore any requests using the methods PROPFIND or OPTIONS, and I also tried the reverse of ignoring any requests that weren't using GET, POST or HEAD methods. Neither method resolved the problem.
