Creating patches - svn diff and moved files

[Simon Brunning <si...@brunningonline.net>]

I've been using svn diff to generate patches, but I've noticed a
problem. If I move a file using svn mv, the new version of the file
isn’t included in the output of svn diff.

Is there a way to make svn diff include moved files? If not, what's
the recommended way to generate patches?

Files that are marked added-with-history are not included in the
output of svn diff. (Remember: the target of a 'move' is like a
target of a 'copy' which is like an 'add' with history. Yes, this
is confusing.)

I can only explain the technical reason why it happens but I don't
know the reasoning behind why Subversion was designed this way:

'svn diff' compares the working version with the text base it has
for the file (in .svn/text-base/).  If you add a file with history
you get a new text base for it, and the content of the working file
will match the text base, hence you get no diff.

Note that the file shows up in the diff if you modify it after
moving it.

The branch has been merged into trunk. This functionality will
be in Subversion-1.7.

I see I'm not alone in having this problem - see
<http://tinyurl.com/4zphfa> and <http://tinyurl.com/dy8grw> - but I
can't find a solution anywhere.

Anyone know what happened to the svnpatch-diff branch at
<http://tinyurl.com/chrlso>? It looks like this was intended to give
svn the ability to take and apply patches including file moves and
renames and property changes, which would be great. But sadly the
branch appears moribund.
