Review Board error with Subversion diff
Review Board 1.6.6 chokes on some diffs generated by Subversion 1.7.4. The error given is:
The file 'https://path-to-file-in-repo' could not be found in the repository
The problem seems to be with files that have been copied from elsewhere in the repository and then modified. Subversion generates a diff to show the changes to the file. Unfortunately Review Board doesn't realise the diff is taken against a file in a different location.
The diff is generated with the
svn diff and produces a header like this:
Index: path/to/file =================================================================== --- path/to/file (working copy) +++ path/to/file (working copy)
The solution is to tell Subversion to pretend the file is newly added by using the
--show-copies-as-adds option. With this option a different header is produced:
Index: path/to/file =================================================================== --- path/to/file (revision 0) +++ path/to/file (working copy)
Review Board accepts diffs created with this option without any problems. A downside is that some of the file history is missing for the reviewer.
Note: I didn't try using the
post-review tool, which I think is the recommended way to generate diffs for Review Board.
