Some of you may remember that when talking about what kind of
concurrency should be added to Emacs (locks, transactions, younameit),
I was of the opinion that we should stick to cooperative for now and we
may never want to move away from it because there might be a way to make
it parallel. You may also remember that I was referring to a work that
I couldn't find any more.
Well, I think I found something related: http://ocm.dreamhosters.com/
I'm not sure whether such an approach is workable for Elisp (the
optimistic STM approach is not workable because of the difficulty of
unrolling side-effects, and it might be difficult to avoid deadlocks in
the lock-based approach), but I think it's an interesting direction if
we want to preserve enough backward compatibility.

Coccinelle is a tool that generates diff files for an entire source tree based a semantic rules. Think of it as a _really smart_ sed with operators and constructs for C. It's already used in the linux kernel so it's production ready. 1: http://coccinelle.lip6.fr Tutorial: http://home.regit.org/technical-articles/coccinelle-for-the-newbie/ ^ permalink raw reply [flat|nested] 4+ messages in thread

BTW, it might also be neat to try and get rid of the GCPRO stuff by replacing it with a coccinelle "semantic patch". Stefan ^ permalink raw reply [flat|nested] 4+ messages in thread
