------- Additional comments from pburba@tigris.org Fri Jul 29 08:26:40 -0700 2011 \
------- When a subtree is added by a merge, if the incoming subtree has its own \
explicit mergeinfo, we currently don't update that mergeinfo to describe the merge.
Worst case this causes spurious merge conflicts in subsequent merges, best case
it results in wasted time on noop editor drives (with the attendant merge
notifications which are possibly confusing since there may be no local
modifications post-merge).
We can see this in our own repository on the
^/subversion/branches/gpg-agent-password-store branch in r1139384 'Sync the
gpg-agent-password-store branch with trunk'.
In that sync merge, the subtree
gpg-agent-password-store/subversion/libsvn_subr/svn_temp_serializer.c is added:
c:\SVN\sandbox\merge-mem-use\gpg-agent-password-store>svn log
^^/subversion/branches/gpg-agent-password-store@1139384 -r1139384 -v

In r1139384 the root mergeinfo is updated as expected for /trunk, catching up
from the last sync merge:

But the mergeinfo on the newly added svn_temp_serializer.c subtree is not
updated to describe the merge and only has the mergeinfo from its copy source:
C:\SVN\sandbox\merge-mem-use\gpg-agent-password-store>svn pg svn:mergeinfo
^^/subversion/branches/gpg-agent-password-store/subversion/libsvn_subr/svn_temp_serializer.c@1139384
/subversion/trunk/subversion/libsvn_subr/svn_temp_serializer.c:1067687-1072301
c:\SVN\sandbox\merge-mem-use\gpg-agent-password-store>svn pg svn:mergeinfo -v
^^/subversion/trunk/subversion/libsvn_subr/svn_temp_serializer.c@1139365
Properties on
'http://svn.apache.org/repos/asf/subversion/trunk/subversion/libsvn_subr/svn_temp_serializer.c':
svn:mergeinfo
/subversion/trunk/subversion/libsvn_subr/svn_temp_serializer.c:1067687-1072301
This is a problem because subsequent sync merges will detect what it thinks are
operative revisions on svn_temp_serializer.c and try to merge them, possibly
resulting in conflicts. We can see this if we repeat the sync merge of r1139384
(We'll confine the merge target to libsvn_subr to keep things simple, but the
same thing happens if targeting the root of the branch):
