Re: Revision graph speed

It's my understanding that the revision graph is currently so slow
because it has to get the full log and then basically scan through the
entire thing to search for all copy entries. Has there been any talk
of adding to subversion the ability to find where a file has been
copied to? Basically storing the copy information bi-directionally.
Right now, only the new copy has information on where it was copied.
However if the repository stored with the original copy information on
where it has been copied to in addition to where it was copied from
and this data could be queried, than generating a revision graph would
be trivial.

However this would require a change in repository format, so I imagine
it wouldn't be a simple feature to add and would require both a newer
client and server. Still though, does anyone know if there's been any
talk of adding this in a future version of Subversion? Revision graph
has plenty of uses and it'd be much nicer if it could be generated
just by a quick traversal of the one object's tree in both directions
rather than reading and analyzing the entire repositories log.
