F9: Unable to get SVN/Apache working

[Daniel B. Thurman]

Previous posting broken off from thread:
"F9: Eclipse plug: Subversive SVN does not work?"

I posted previously thinking that there was a problem
with eclipse/netbeans, but it was not.  I have decided
to create a new thread focusing exclusively on SVN/Apache
issues, thus this "new" posting.

To make a long story short, I have been able to get my
SVN working with the svnserve daemon and it works.
However, I am unable to get SVN/Apache to work.

My SVN repository directory structure is:
===========================
/svn --> /f-App1/Develop/SC/svn
/f-App1/Develop/SC/svn:
  apache
    passwords svnauthz.conf
    [ # cat svnauthz.conf :
          [groups]
           home = user1.user2,user3
            [/]
            * = r
            [svn3:/]
            * =
            @home = rw
    ]
  repos
    svn1 svn2 svn3 svn4
    Note:
      1) All selinux contexts of dir/files are: httpd_sys_content_t
      2) All directory permissions are: 2770
      3) All file permissions are: 660
      4) All svn[1-4]/conf files are linked to apache/files for svnserve 
daemon
  svnserve
    authz  passwd  svnserve.conf
===========================

I have created a simple apache construct in
/etc/httpd/conf.d/subversion.conf as:
===========================
<Location /svn>
   DAV svn
   SVNParentPath /svn/repos
#   AuthzSVNAccessFile /svn/apache/svnauthz.conf
#   AuthUserFile /svn/apache/passwords
#   AuthType Basic
#   AuthName "Authorization Required"
#   Require valid-user
#   Satisfy any
</Location>
===========================

Starting httpd, results in error_log as:
===========================

[Sun May 03 13:25:11 2009] [error] avahi_client_new() failed: An 
unexpected D-Bus error occured
=============================

Note: I have tried to resolve the avahi_client_new() error above but 
unable to fix it. No
          response from Fedora community as to what this error might 
mean.  I have removed
          all extra avahi packages, short of removing too many 
dependencies.  So, for the moment
          I have ignored this error.  Also, as appeared in the original 
posting, Apache's mod_security
          was reporting "errors", so I removed mod_security so that 
these messages do not appear
          for the purpose of testing and getting svn/apache setup right 
before adding it back in.

Tested svn using Firefox, using URL: http://localhost/svn/svn3/:
===================
Revision 2: /

    * branches/
    * tags/
    * trunk/

Powered by Subversion version 1.4.6 (r28521).
===================

But httpd error_log shows:
===================
[Sun May 03 14:00:56 2009] [error] [client 127.0.0.1] Could not fetch 
resource information.  [301, #0]
[Sun May 03 14:00:56 2009] [error] [client 127.0.0.1] (84)Invalid or 
incomplete multibyte or wide character: Requests for a collection must 
have a trailing slash on the URI.  [301, #0]
===================

However, it seems to work.  I can walk down the trees to
the leafs and no further error_log messsages appear.

Next, I tested svn on the command line:
===================
$ svn list http://gold/svn/svn3
svn: PROPFIND request failed on '/svn/svn3'
svn: PROPFIND of '/svn/svn3': 403 Forbidden (http://gold)
===================

And httpd error_log shows:
===================
$ svn list http://localhost/svn/svn3
svn: PROPFIND request failed on '/svn/svn3'
svn: PROPFIND of '/svn/svn3': 403 Forbidden (http://localhost)
===================

I have at this point, tried almost every permutations of changing dir/file
permissions, relocating the repositories to: /var/www and to /var/www/html,
modifying subversion.conf, checked apache permissions (Allow from all) in
/etc/httpd/conf/httpd.conf & subversion.conf files, checked the firewalls
(they are wide open) and I could never get past the PROPFIND,
403 Forbidden problem.

I cannot think of anything else to try, so I am at a stand-still.

Can someone help?

Thanks!
Dan
