You are nesting locations. This isn't a valid configuration because it
leads to ambiguity when splitting a URL into the part which is outside
of the repository and the part which is inside the repository.
Why this configuration is not valid?
Before Subversion gets called, Apache HTTPD decides which Location
block gets to handle a request. Subversion has no control over this decision.
Note that Apache HTTPD looks only at URLs. It has no idea and does not care
whether or not there is a Subversion repository anywhere within the URL
http://svn.example.com/svn/foo/bar/baz
With your configuration the URL has two possible repositories:
http://svn.example.com/svn/foo
http://svn.example.com/svn/foo/bar
So how is Apache HTTPD supposed to tell which of your Location blocks
should handle requests for the URL http://svn.example/com/svn/foo/bar/baz?
Should<Location /svn> handle it or should<Location /svn/foo> handle it?
Of course "/svn/foo".
Locations are worked down from shortest URI. So correct SVNParentPath
must be passed to mod_dav_svn.
The documentation at
http://svnbook.red-bean.com/en/1.7/svn.serverconfig.httpd.html#svn.serverconfig.httpd.basic
says:
======
Be sure that when you define your new Location, it doesn't overlap with other
exported locations. For example, if your main DocumentRoot is exported to /www,
do not export a Subversion repository in<Location /www/repos>. If a request
comes in for the URI /www/repos/foo.c, Apache won't know whether to look for a
file repos/foo.c in the DocumentRoot, or whether to delegate mod_dav_svn to
return foo.c from the Subversion repository. The result is often an error from
the server of the form 301 Moved Permanently.
======
The error you see is not 301 but the root cause of the problem is the same.
I disagree. This cite is irrelevant to my issue.
It worked in 1.6 servers. It seems like regression.
I am surprised that it worked.
I am not, because it's correct way.
Also, in 1.7 reading repos is working fine:
"OPTIONS /svn/foo/bar HTTP/1.1" 200
"REPORT /svn/foo/bar/!svn/me HTTP/1.1" 200
but only POST fails:
"POST /svn/foo/bar/!svn/me HTTP/1.1" 500
So the problem is not in Apache or configuration but in mod_dav_svn itself.
It is obviously a regression.
I want to avoid use SVNPath for every leaf repo in the root.
SVNParentPath is intended for such purpose.
Also I want to use SVNListParentPath to autogenerate normal listing.
It's impossible with multiple SVNPath.
You have repositories in /usr/home/svn and also /usr/home/svn/foo.
This is a bad way of organising your repositories because there is
no unique way to map URLs to repository roots.
I disagree, see above. There are robust way to handle <Location>s in Apache.
I prefer to organize my repos in this way because is "natural".
Similar to filesystems: I like to place files and organize them to
folder/directories as I want to.
Put your repositories into distinct, and flat, directories.
Don't nest them in a tree.
Move some of your repositories into /usr/home/svn/foo and some into
/usr/home/svn/bar, and change your configuration file to look like this:
[skip]
This will give you a setup that works reliably.
