Oops, sent this to xorg at lists.freedesktop.org not xorg@:
Wondering if anyone has any insight on this problem.
I'm trying to think of ways to handle protocol revisions in xcb. Are
there guidelines about what is allowed/not allowed for protocol revisions?
Most of the extension revisions I've seen add events or new
requests/replies, these are all very easy to deal with. The one big
question (has the most implications on the client-side library) is:
Are requests/replies ever extended (more bits over the wire) in newer
I am unsure how to handle the case where the client uses a
request from an older version of the extension that has now changed its
signature in a later version of xcb.
