RE: can mod_dav_svn 1.5 deny access from earlier clients?

(copied to dev@... as I think this one's a defect).

Except that this appears to be broken if you're using mod_dav_svn 1.5.0.

As previously posted by Jacky-10:

I've confirmed this in an ethereal session (attached) - the capabilities
parameters are listed in the DAV: parameters passed to the HTTP request
but are not being passed through to the start-commit script.

OPTIONS /svn/repos/david.x.grierson/trunk/src HTTP/1.1
User-Agent: SVN/1.5.0
Connect: TE, Keep-Alive
TE: trailers
DAV: http://subversion.tigris.org/xmlns/dav/svn/depth
DAV: http://subversion.tigris.org/xmlns/dav/svn/mergeinfo
DAV: http://subversion.tigris.org/xmlns/dav/svn/log-revprops
Accept-Encoding: gzip

Whereas the the start-commit output is:

svn: Commit failed (details follow):
svn: Commit blocked by start-commit hook (exit code 1) with output:
Repo path: [/opt/svnroot/david.x.grierson]
Username: []
Capabilities: []

Sorry - you are using a pre-1.5.x Subversion client - exiting!

start-commit hook script and ethereal session attached.


I'll raise this as a defect against 1.5.0 - I don't have a build of 1.5.1
yet so can't confirm whether it's still present in that.

This is addressed in the book:
