[Gnu-arch-users] strategy/code for migrating changesets out of arch

[Dustin Sallings]

	At work, we use perforce.  It's good enough when it and the network 
works, so I've not been pushing arch to my group.  I have, however, 
been trying to use it myself.  In doing so, I've created a utility to 
migrate changesets applied to a particular section of a depot 
overlapping an arch tree back into arch.  It works pretty well and I 
seem to be getting all of our checkins into my arch mirrors.

	Although I can branch this tree and work in it just fine, I don't have 
anything to reapply those changesets back into a p4 tree.  Does anyone 
have anything that might help comprehend arch changesets so I can apply 
the changes back to p4?

	Ideally, a python class I can ask for new files, deleted files, 
modified files, etc... might be good...or to just iterate the changes.  
Migrating from p4, I'm using p4lib, which gives me file-level changes 
within a changeset by file including operation.  I translate those p4 
operations to tla operations using the following map:

actions={'branch': 'add-id', 'add': 'add-id',
    'edit': '', 'integrate': '',
    'delete': 'delete-id'}

	Being able to do that in the opposite direction would be very cool, 
and I'm more likely to do it sooner if pointed to reasonable migration 
code.
