You are demonstrating lack of knowledge on topic discussed. The
svn_fs_move() *does* change disk format. Could you please be so kind
to learn code before objecting:
subversion\libsvn_fs_fs\tree.c:copy_helper() is a good starter. Thank

The same problem here. Maybe I'm wrong but it seems that you do not
fully understand the current state of the FSFS code. It so happened
that I've found and fixed several nasty bugs in FSFSv6 and FSFSv7. And
I'm just trying to say that we should not release FSFSv7 in the
Anyway, you can just close issue #4502 if I'm wrong and you are
clearly understand the code and related FSFSv7 format changes. Maybe
I'm too conservative and care too much about the quality. Time will
