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/libkse/thread/thr_create.c | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'lib/libkse/thread/thr_create.c') diff --git a/lib/libkse/thread/thr_create.c b/lib/libkse/thread/thr_create.c index deb26de..4c65d3c 100644 --- a/lib/libkse/thread/thr_create.c +++ b/lib/libkse/thread/thr_create.c @@ -297,6 +297,13 @@ _pthread_create(pthread_t * thread, const pthread_attr_t * attr, * pair if necessary. */ ret = _thr_schedule_add(curthread, new_thread); + if (ret != 0) { + KSE_LOCK_ACQUIRE(curthread->kse, + &_thread_list_lock); + THR_LIST_REMOVE(new_thread); + KSE_LOCK_RELEASE(curthread->kse, + &_thread_list_lock); + } _kse_critical_leave(crit); if (ret != 0) free_thread(curthread, new_thread); -- cgit v1.1
