I understand what you're talking about. Two comments:
- I believe that over ra_local and ra_svn, such not-really-mixed-rev
working copies would still wind up doing what you would expect
because libsvn_fs checks to see if a copy would result in no real
change, and if so, does nothing. ra_dav has a problem here, in
that mod_dav flatly hijacks the ability for a copy to overwrite
an existing object. (There's an issue in our tracker that covers
- The full "fix" for what you're talking about likely involves the
Subversion client code doing all the work that the Subversion
server code does right now to determine if a copy would be a
no-op. Trust me -- replicating that logic is a bad idea (for
