Please provide any additional information below.


rbt diff shows:


Index: file
===================================================================
similarity index 100%
rename from file
rename to file_moved





If file contains some modifications, all are visible as changes in old name 'file'

Some more comments, IMHO in this situation diff should looks same as from pure svn, so in diff 'file' should be mareked as removed and file_moved as added.

Any possibility to fix this?

I am having the same issue. This also highlights a discrepancy in the way the ReviewBoard displays diffs between git and svn.  In pure git, when a file is moved ReviewBoard (the UI) shows the file one time and marks it as moved. In svn, a moved file will either just show up once and not be marked as moved, or show up twice and be marked as removed/added. There is an svn-specific option (--svn-show-copies-as-adds) for RBTools that controls this. When a file is moved and changed it will be even more confusing in ReviewBoard for svn. If --svn-show-copies-as-adds=y is used, then two copies of the file are shown with no diff to show the change, so ReviewBoard is almost useless for analyzing what changed. If --svn-show-copies-as-adds=n is used then two copies are still shown, but at least once of them shows the rename and diff - which is great. The other copy that shows the file as deleted serves no purpose since the file was already marked as moved.


I think the way that ReviewBoard does it for git is more intuitive. Just show the file once and mark that it was moved (with diffs if applicable). ReviewBoard should behave in the same manner for git, svn, and git-svn.


It would be great if this could be fixed!
