ojacobson was my hero - the file was locked, even tho it didn't exist.

We found it with "svnadmin" on the server.

[root@tracserver tempo]# svnadmin rmlocks /data/svn_repos/vhdl_bn /bn.bit

Don't miss the space in the above line.

[root@tracserver tempo]# svn ci -m "Adding fake BIT file" --username admaras
Adding         bn.bit
svn: Commit failed (details follow):
svn: Cannot verify lock on path '/trunk/vhdl_bn/bn.bit'; no matching lock-token available

Umm... what? I think I have figured it out - the file previously existed, was locked, and then deleted and the lock didn't get cleared?

Applicable possible locations:

<Location />
  # Redirect to trac only
        RewriteEngine On
        RewriteRule ^/?var/www/html/?$ /trac/ [R=301]
</Location>

<Location /svn>
   DAV svn
   SVNParentPath /data/svn_repos
   <LimitExcept GET PROPFIND OPTIONS REPORT>
      AuthType Basic
      AuthName "Subversion"
      AuthUserFile /data/trac_repos/.htpasswd
      Require valid-user
   </LimitExcept>
</Location>

This gets interesting (suggested by ojacobson):

admaras@brisingamen ~/tempo
$ svn cat http://192.168.x.x/svn/vhdl_bn/bn.bit
svn: GET of '/svn/vhdl_bn/!svn/bc/84/vhdl_bn/bn.bit': 404 Not Found (http://192.168.x.x)

admaras@brisingamen ~/tempo
$ svn cat http://192.168.x.x/svn/vhdl_bn/BN.bit
svn: PROPFIND request failed on '/svn/vhdl_bn/!svn/bc/84/vhdl_bn/BN.bit'
svn: '/svn/sunsignal/!svn/bc/84/vhdl_bn/BN.bit' path not found

So... one is a 404 the other is an invalid path. How weird.

I did "svnadmin verify ." on the server with no results.
