One difference, though. svnsync fails before it makes any changes to the
destination repository (because do_init() and get_lock() create
revprops.) I think svnrdump might be failing in replay_revend(), after
the revision *has* been committed, but before svnrdump has touched the
svn:{date,author} revprops on the destination.
Also, this race condition exists anyway... (if eg I cut the network
cable upon entry to replay_revend()) so we should document this clearly
in 'svnrdump load', or give a very clear error message (to indicate that
the revision was *partially* loaded --- content and revprops, but not
author or date) in that case.
Could you look into this please? (i.e., whether the race condition
exists, and if yes then make sure the error message explains the
situation clearly)
