From 450463d5fbc7098666c1405b5ea1ece4c8dd04a5 Mon Sep 17 00:00:00 2001 From: ko1 Date: Sat, 27 Nov 2010 20:15:59 +0000 Subject: * thread.c, vm_core.h: make gvl_acquire/release/init/destruct APIs to modularize GVL implementation. * thread_pthread.c, thread_pthread.h: Two GVL implementations. (1) Simple locking GVL which is same as existing GVL. (2) Wake-up queued threads. The wake-up order is simple FIFO. (We can make several queues to support exact priorities, however this causes some issues such as priority inversion and so on.) This impl. prevents spin-loop (*1) caused on SMP environemnts. *1: Only one Ruby thread acqures GVL again and again. Bug #2359 [ruby-core:26694] * thread_win32.c, thread_win32.h: Using simple lock not by CRITICAL_SECTION but by Mutex. Bug #3890 [ruby-dev:42315] * vm.c (ruby_vm_destruct): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@29956 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- thread_win32.h | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) (limited to 'thread_win32.h') diff --git a/thread_win32.h b/thread_win32.h index ec2930df12..b7ab91ea44 100644 --- a/thread_win32.h +++ b/thread_win32.h @@ -23,11 +23,18 @@ TryEnterCriticalSection(IN OUT LPCRITICAL_SECTION lpCriticalSection); typedef HANDLE rb_thread_id_t; typedef CRITICAL_SECTION rb_thread_lock_t; -typedef struct rb_thread_cond_struct rb_thread_cond_t; +typedef struct rb_thread_cond_struct { + struct cond_event_entry *next; + struct cond_event_entry *last; +} rb_thread_cond_t; typedef struct native_thread_data_struct { HANDLE interrupt_event; } native_thread_data_t; +typedef struct rb_global_vm_lock_struct { + HANDLE lock; +} rb_global_vm_lock_t; + #endif /* RUBY_THREAD_WIN32_H */ -- cgit v1.2.1
