Re: [APC-DEV] Spinlock code

I'd be interested in doing this, assuming no one wants to jump up and do it first. I have pthread mutex locking support that I would like to finish up first. (as a better alternative to the futex locking). On Dec 10, 2006, at 6:18 PM, Rasmus Lerdorf wrote:

Anybody feel like taking a shot at implementing spinlocks? I have been looking through the Postgres-8.2 code and I talked a bit with Bruce Momjian about their implementation and I think we could lift a good amount of code to get portable spinlocks from them. See: postgresql-8.2.0/src/include/storage/s_lock.h And also see how they are used in: postgresql-8.2.0/src/backend/storage/lmgr/lwlock.c PostgreSQL is completely BSD-licensed, so it is a good place to steal code from. -Rasmus --APC Development Mailing List (http://pecl.php.net/APC) To unsubscribe, visit: http://www.php.net/unsub.php
