Hi Kate,

It sounds like you have a similar issue to one that I posted about a
month or so ago. I put our upgrade from 1.4->1.5 on hold until it's
fixed. It is still an issue with 1.5.3. Maybe we can find some
commonality in the problem? I used Wireshark to trace the conversation
with the server which gives a little more information than neon. It
certainly seems that the following command causes my issue:

REPORT /projects/!svn/bc/0/dairy/trunk HTTP/1.1

The problem is that /dairy/trunk was called something different in
earlier revisions. Does anybody know what the zero in the REPORT url
means? Is bc/0 the first revision? Does your error occur on the report
command?

Kate, if you make any headway, can you please update me, and vice versa.

Kind Regards,

Olly

----- My Old Post -----------------
Hi,

I have been tracking the progress of merging in SVN with excitment. When
1.5.0 was released, I downloaded a copy and tested it with a copy of our
existing repository. I found a couple of merge related issues. When I
looked at the svn issue tracker, I found that there was some fixed
issues in 1.5.1 that sounded similar to the problem I was seeing. I
retested. Some issues went away, but one remains, and remains in 1.5.2.
So...

Our repository is structured as follows:

projects
        ->dairy
               ->trunk
               ->branches
                         ->branch1, etc

For our tests, I copied the trunk into dairy folder as copy1. The
operation completed successfully. I then modified the copy1 tree with
additions, deletions and modifications, and committed. Next I changed
into the trunk folder and executed

svn merge http://svn.foo.com/projects/dairy/copy1 .

SVN returns "svn: Target path does not exist". It seems that in the past
the trunk folder was renamed, and somehow the merge is getting confused.
It is worth noting that svn:mergeinfo property is empty at this point. I
cleared it out because the python svnmerge upgrade script does not seem
to order revisions correctly, so I deleted the contents of
svn:mergeinfo.

Anyway, so I believe there is a problem with the lookup of the history
when merging. I executed the operation over http and captured the
conversation with the server with wireshark. See below.

I you need any more information, I would be happy to oblige. P.S.
Unfortunately the repository is not public facing.

Regards,

Oliver
