Hello Hans

As far as I can see we can get the required merge information by using the
following SVN command
* SVN LOG -G -V -R X:Y * where X and y is a revision range involved.

The above command will fetch the history of each revisions along with its
corresponding mergeinfo (if any). I tried

svn log -g -v -r 39834 http://svn.collab.net/repos/svn/branches/1.6.x

http://old.nabble.com/file/p26844541/MergeInfoUsingLOG%2BG.txt
MergeInfoUsingLOG+G.txt

and attached the output file here.So I dont think so we should do log ,
check for Properitychanges or so.

So I am right now analysing TSVN Cache structure, Once it is known we can
just store the collected data into the cache and retrieve it back for
generating graphs.

1. First thing is that we should analyse how exactly the cache file is
created from log and how can we
add data into that cache so that it is not breaking the backward
compatibility. ( Must do some tweaks to CRootOutputStream or any class
related to that) I am looking at that right now.

2. Once that is done, We need to study how the data is again retrieved from
that cache file(Using Indexpairdictionary and revision index)

Any Suggestions ??

Thanks & Regards,
S V Ram
