From 6deabb439b7870759f16db0c9a3968e3755bf61a Mon Sep 17 00:00:00 2001 From: deischen Date: Mon, 28 Apr 2003 23:56:12 +0000 Subject: o Don't add a scope system thread's KSE to the list of available KSEs when it's thread exits; allow the GC handler to do that. o Make spinlock/spinlock critical regions. The following were submitted by davidxu o Alow thr_switch() to take a null mailbox argument. o Better protect cancellation checks. o Don't set KSE specific data when creating new KSEs; rely on the first upcall of the KSE to set it. o Add the ability to set the maximum concurrency level and do this automatically. We should have a way to enable/disable this with some sort of tunable because some applications may not want this to be the default. o Hold the scheduling lock across thread switch calls. o If scheduling of a thread fails, make sure to remove it from the list of active threads. o Better protect accesses to a joining threads when the target thread is exited and detached. o Remove some macro definitions that are now provided by . o Don't leave the library in threaded mode if creation of the initial KSE fails. o Wakeup idle KSEs when there are threads ready to run. o Maintain the number of threads active in the priority queue. --- lib/libpthread/thread/thr_find_thread.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'lib/libpthread/thread/thr_find_thread.c') diff --git a/lib/libpthread/thread/thr_find_thread.c b/lib/libpthread/thread/thr_find_thread.c index b5cae66..0c813db 100644 --- a/lib/libpthread/thread/thr_find_thread.c +++ b/lib/libpthread/thread/thr_find_thread.c @@ -85,6 +85,9 @@ _thr_ref_delete(struct pthread *curthread, struct pthread *thread) KSE_LOCK_ACQUIRE(curthread->kse, &_thread_list_lock); thread->refcount--; curthread->critical_count--; + if ((thread->refcount == 0) && + (thread->flags & THR_FLAGS_GC_SAFE) != 0) + THR_GCLIST_ADD(thread); KSE_LOCK_RELEASE(curthread->kse, &_thread_list_lock); _kse_critical_leave(crit); } -- cgit v1.1
