How can you list all subversion merges?
For example:
Trunk ____9_____14____20___
\\ \\ \\
\\______\\_____\\____
Branch01
During each merge operation, the svn:mergeinfo property is changed to record the merge. The mergeinfo will be on Branch01
in this case. Subversion only records where changes are merged from, not where they are merged to.
I'm not sure if it's enough in your use case, but you could try to find out all revisions of Branch01
that have mergeinfo changes?
