Hello, I'm hitting what appears to be a bug in subversion. The problem is that I get incorrect subtree mergeinfo after a merge to my branch; the subtree is not recording the merge, and this later prevents reintegrate from working (via "Reintegrate can only be used if revisions [X] through [Y] were previously merged from [URL]..."). It appears that this bug is triggered by a differentbranch->trunk cherrypicking merge earlier in the history of the subtree.
I've distilled this down to a simple test case that reproduces the problem. The
attached "cherrypick-mergeinfo-fail-test.sh" script will run the steps
necessary to demonstrate. I've also attached the output this script generates
as "cherrypick-test-output.txt", so you can see the problem without running the
script.
I'm still on subversion 1.6.5 (r38866), but the 1.6.6 CHANGES file doesn't
appear to address this. I've tried this on a standard Mac OS X SnowLeopard
(10.6.2) system with the system install of subversion.
Is there something I've actually done wrong here that's triggering the problem?
Or does this appear to be a bug?
Thanks very much,
- Rick Ballard

svn: Reintegrate can only be used if revisions 7 through 10 were previously
merged from file:///Users/rick/Desktop/repos/trunk to the reintegrate source,
but this is not the case:
