Subversion merge behavior

Question

I have created a quick example to demonstrate my question. From the log below you will see following:

1. r1 - created trunk
2. r2 - created branches
3. r3 - added foo.txt into trunk
4. r4 - created QA branch
5. r5 - created UK branch
6. r6 - created TEAM branch
7. r7 - updated foo.txt and added bar on TEAM branch
8. r8 - merged TEAM into QA
9. r9 - merged QA into trunk

So my question is when I try to do, svn merge -r9:HEAD ^/trunk from within UK directory I don't get the r9 changes is this the expected behavior?

svn log -v -g ^/

Answer 1

You need to specify one revision less than your intended ones, so try

svn merge -r8:HEAD ^/trunk

Answer 2

You can omit merge-range in your simple case. But andreas is perfectly correct: range is not inclusive for start-border
