I just copied my svn folder, and when I merge it, it shows differences between folders when there's none. What's wrong here?

My subversion is wrongly showing that my folder "x" is different from the branch to the trunk, even right after I create the branch.

I created the branch using the command:

svn copy mytrunk mybranch

commited the branch:

svn ci mybranch -m "creating my branch"

and did the merge (to make sure nothing was different):

svn merge <mybranch-url>

and when I give an svn status, it shows that 3 folders are modified (including the root):

 M      .
 M      a/b/aFolder
 M      x/y/anotherFolder

Note that it's saying that the folders are modified, but no file inside them is modified..

What is wrong here?

--update: even if I c开发者_运维知识库ommit the "modified" folders, when I do the svn merge again say it's modified again.

On merges SVN updates internal properties named mergeinfo. To inspect the actual properties that have changed with the merging on a/b/aFolder you can issue:

svn propget svn:mergeinfo a/b/aFolder
