Hi,
vila:~/tmp :) $ mkdir bug
vila:~/tmp :) $ cd bug
vila:~/tmp/bug :) $ bzr init
vila:~/tmp/bug :) $ echo tagada >toto
vila:~/tmp/bug :) $ bzr add toto
added toto
vila:~/tmp/bug :) $ bzr commit -m "toto created"
Committed revision 1.
vila:~/tmp/bug :) $ bzr rename toto foo
vila:~/tmp/bug :) $ bzr cat --revision 1 foo
bzr: ERROR: exceptions.NameError: global name 'BzrError' is not defined
at /home/vila/dune/src/bzr.dev/bzrlib/repository.py line 263
in print_file
vila:~/tmp/bug :( $ bzr cat --revision 1 toto
tagada
vila:~/tmp/bug :) $
Doing some research I found:
https://launchpad.net/products/bzr/+bug/3630
So I understand this is a known bug, but at least the error
message could be made clearer.
The following patch did the trick.
I was really enjoying renaming files with bzr (coming from CVS),
I'm a bit less enthusiastic now :-/
Thanks in advance to whoever will push this bug up in its TODO
stack :-)
Vincent
