Subject: [users@httpd] Apache 2.0.52, Subversion 1.1.3, and Slackware 10

Hey guys,

I am trying to setup a Subversion repository on my slack 10 box. I have 
upgraded to apache 2.0.52 using the package at linuxpackages.org. I have 
installed the Subversion 1.1.3 package from there as well.

I can create the repository, and access it locally just fine. I added 
this to my httpd.conf:

--------------------------------------------------------------------------------------------------- 


LoadModule dav_svn_module lib/apache2/mod_dav_svn.so
LoadModule authz_svn_module lib/apache2/mod_authz_svn.so

DavLockDB /var/DavLock

<Location /svn>
Dav svn
SVNPath /var/repository/
AuthType Basic
AuthName "Subversion Repository"
AuthUserFile /etc/apache2/passwd/subversion-access
Require valid-user
</Location>
--------------------------------------------------------------------------------------------------- 


Here are the permissions on the Repository:

Apache runs as nobody:nogroup

I can access my local webpages via apache just fine.  I can access 
regular DAV sites just fine, (I use the Firefox Bookmark Syncronization 
extension) using DAV On.

When I have the authz_svn_module loaded, and try to access one of my 
normal (non-dav) pages that use Auth Basic authentication, they fail. I 
just get a blank page. When I don't load authz_svn_module, my pages load 
fine.


When I try to access my (url)/svn using subversion, Apache segfaults.
my doc-root is /var/www/htdocs.
Looking at the strace output, it seems like apache is looking for 
/var/www/htdocs/svn instead of following the Location tag and enabling 
the DAV handler. Here is the strace output:

------------------------------------------------------------------------------------------------------ 


I am hoping that I just forgot to do something in my httpd.conf. I don't 
understand why, #1, apache is still looking at /var/www/htdocs/svn, #2, 
it is segfaulting, or #3, why mod_authz_svn would affect auth-basic 
authentication in any way.

Any information or suggestions is appreciated.

Thanks,

Andrew
