Add a simple work-around for deadlocking on recursive read locks 2004-01-08T15:37:09+00:00 Daniel Eischen deischen@FreeBSD.org 2004-01-08T15:37:09+00:00 24f33bca1c2f4207c48830f893ee5a07e3c4402e on a rwlock while there are writers waiting. We normally favor writers but when a reader already has at least one other read lock, we favor the reader. We don't track all the rwlocks owned by a thread, nor all the threads that own a rwlock -- we just keep a count of all the read locks owned by a thread. PR: 24641

Revamp libpthread so that it has a chance of working in an SMP 2003-04-18T05:04:16+00:00 Daniel Eischen deischen@FreeBSD.org 2003-04-18T05:04:16+00:00 a0240e2cb0b1ef8e5b61930ac2b850c884daaba8 environment. This includes support for multiple KSEs and KSEGs. The ability to create more than 1 KSE via pthread_setconcurrency() is in the works as well as support for PTHREAD_SCOPE_SYSTEM threads. Those should come shortly. There are still some known issues which davidxu and I are working on, but it'll make it easier for us by committing what we have. This library now passes all of the ACE tests that libc_r passes with the exception of one. It also seems to work OK with KDE including konqueror, kwrite, etc. I haven't been able to get mozilla to run due to lack of java plugin, so I'd be interested to see how it works with that.
