Hi Alexey,
Could you compile an SVN client from trunk and try some merges with it,
and let me know how the merging of moves with the new conflict resolver
(which is still work-in-progress) is working out for you?
My goal is to make scripts like yours unnecessary.
The current implementation does not yet detect moves which happened
inside copies, but I hope to get that fixed before release.
Thanks,
Stefan
I gave it a try (r1763039) and it is not different from what I see with
1.9.x: the files that were renamed on the branch are still copied from the
branch, not renamed on the trunk.
I.e.,
svn cp $SVNREPO/trunk $SVNREPO/branch/x
svn co $SVNREPO/branch/x
cd x
svn mv foo.c bar.c
vi bar.c
svn ci
cd ..
rm -rf x
svn co $SVNREPO/trunk
cd trunk
svn merge ^/branch/x
svn info bar.c
The last command shows bar.c as being copied, without any changes, from
^/branch/x/bar.c - rather than being copied from ^/trunk/bar.c and modified.
And, since there are no changes in the diff, ReviewBoard shows nothing in
the diff for bar.c.
You'll have to produce some kind of tree conflict involving the renamed file.
The run 'svn resolve' (or use the conflict prompt 'svn merge' opens for you).
To be clear, 1.10.x will *not* change 'svn merge'.
It changes post-merge behaviour during tree conflict resolution only.
I'm afraid this won't fix your problem with ReviewBoard.
Well, tree conflicts during merge is a separate pain point with SVN, but
here I was referring specifically to the reviewability of the merges -
so 1.10 will not make this script obsolete, unfortunately. Perhaps, the
change in merge behavior can be made conditional on some command line
option, e.g. 'svn merge --replay-merged-renames'?
Also, I was just made aware that the script I posted has a shortcoming
if the branch being merged has been previously merged into trunk, and
then had seen more development on the branch (i.e., it is a branch for
ongoing development, not "merge-and-delete" branch). Thing is, it is not
very straightforward with Subversion to discover *where this file has
been copied to*. For example, "I have a file foo.c in revision 111;
under which name(s) is this file appearing in HEAD?" I think adding an
ability to obtain this kind of information has been discussed in the
past - is it on the table for 1.10?
Regards,
Alexey.
