SVN tree conflict when merging renamed folder

问题

I'm using TortoiseSVN to merge into branch-B the latest changes from trunk, including a folder rename.

Before that, I reintegrated branch-A into trunk. In that branch, a folder had been renamed and changes had been made to the files in it. Branch-B contains different revisions to those files, but the folder still has the original name.

When merging trunk into branch-B, SVN simply adds the renamed folder as new, and reports a tree conflict on the originally named folder. The file revisions themselves are never merged and I'm left with both folders. I've tried multiple options to get the cleanest merge possible, while retaining all the appropriate svn:mergeinfo, but nothing seems to work.

Does anybody know the correct way to go about completing this merge cleanly?

TortoiseSVN 1.8.10, Subversion 1.8.11

Here's a visual:

/trunk (before reintegrating branch-A)
  /Folder1
    file1
    file2
    file3

/trunk (after reintegrating branch-A)
  /Folder1-Renamed
    file1-change1
    file2-change1
    file3

/branch-B
  /Folder1
    file1-change2
    file2-change2
    file3

TL;DR: How do I cleanly merge file revisions between two branches when the containing folder has been renamed in one of them?

回答1:

There is no really clean way to resolve structural tree conflicts like this in Subversion. Basically, what you need to do is the following:

merge trunk into branch-B working copy
manually create a diff of the changes to file1 and file2 in branch-B and apply them to the corresponding files in the newly merged Folder1-Renamed directory
delete the now obsolete Folder1 directory
make sure everything still works
accept the current state as the correct one (see also http://svnbook.red-bean.com/nightly/en/svn.tour.treeconflicts.html)
commit

Sorry, it does not get easier than that with svn. I am a big fan of using Subversion for certain kinds of team setups, but the nightmare of tree conflicts (and their arcane and error prone resolution mechanisms) regularly make we want to cry (and switch to git for good).
