What version are you running? ReviewBoard 1.7.21, rbt tools 0.5.5 What's the URL of the page this enhancement relates to, if any? http://mercury/admin/db/scmtools/repository/add/ Describe the enhancement and the motivation for it. We use subversion with a repository that contains dozens of sub-repositories each with dozens of branches. For instance, our base repository path may be https://svn/, under that is https://svn/repo1 https://svn/repo2 https://svn/repo3 ... and within a repo is https://svn/repo1/branches/branch1 https://svn/repo1/branches/branch2 https://svn/repo1/branches/branch3 ... It would be have ReviewBoard know the exact branch the subversion diff is created from. Using rbt post from the branch in question, this seems quite doable. The current workflow is all users need to manually type in the branch (or put it in each .reviewboardrc file in each branch they work on). Of course this is done inconsistently. rbt post would ideally be able to pull this from the URL of the working copy it is run from. What operating system are you using? What browser?
