* vm_core.h (rb_thread_struct): aggregate cpu stuff into a struct,
so that a debugger can show its content at once.

test/ruby/test_exception.rb on Windows.
wrap by __try and __exception statements on mswin to raise SIGSEGV
when EXCEPTION_STACK_OVERFLOW is occurred, because MSVCRT doesn't
handle the exception.
however, (1) mingw-gcc doesn't support __try and __exception
statements, and (2) we cannot retry SystemStackError after this
change yet (maybe crashed) because SEH and longjmp() are too
uncongenial.
* signal.c (check_stack_overflow, CHECK_STACK_OVERFLOW): now defined on
Windows, too.
* thread_win32.c (ruby_stack_overflowed_p): ditto.

Move native thread related lines from vm_core.h.
And declare several functions "rb_nativethread_lock_*",
manipulate locking.
* common.mk: add thread_native.h.
* thread.c: add functions "rb_nativethread_lock_*".
* thraed.c, thread_[pthread,win32].[ch]: rename rb_thread_lock_t
to rb_nativethread_lock_t to make it clear that this lock is for
native thraeds, not for ruby threads.

* thread_win32.c (w32_thread_start_func, thread_start_func_1),
(timer_thread_func): use __stdcall instead of _stdcall which is
unavailable in strict ANSI mode. [ruby-core:55312] [Bug #8495]
* win32/win32.c (gettimeofday): use __cdecl instead of _cdecl.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@41834 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* thread_win32.h (rb_thread_lock_t): make a union for USE_WIN32_MUTEX.
this internal is used only in thread_win32.c, but has to be complete
to define rb_thread_t.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36119 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* thread_win32.c (native_cond_timedwait_ms): rename reserved pattern
name. user defined symbols should not start with __.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36116 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
ruby_thread_from_native() instead of GET_THREAD() because
GET_THREAD() doesn't always return the current thread and
WaitForMultipleObjects() at rb_w32_read() doesn't return by
Thread#kill. This fixes TestQueue#test_thr_kill failure on
Windows.
* thread_win32.c (rb_w32_wait_events): use ruby_thread_from_native()
instead of GET_THREAD() for consistency with the above change.
* thread_win32.c (rb_w32_sleep): ditto.
* thread_win32.c (rb_w32_Sleep): ditto.

RB_RESERVED_FD_P): added. This C API is to limit to access
fds which are used by RubyVM internal. In this version of
CRuby, return 1 if fd is communication pipe.
If your application needs to close all file descriptors to
preent resource leak, skip internal fds using this C API.
We also define a macro RB_RESERVED_FD_P(fd). So you can write
#ifndef RB_RESERVED_FD_P
#define RB_RESERVED_FD_P(fd) 0
#endif
for Ruby 1.9.2 or previous version to write compatible extensions.
See [ruby-core:37727]
* thread_win32.c (rb_reserved_fd_p): added (return 0 for any fds).
* io.c (rb_io_initialize): raise ArgumentError if given fd is reserved by Ruby.

r32244. grep sources before changing the signature of a function.

no waiting thread. If there are 2 or more runnable threads,
the timer thread does polling. Avoid polling makes power save
for several computers (0.2W per a Ruby process, when I measured).
If outside-event such as signal or Thread#kill was occuerred
when the timer thread does not do polling, then wake-up
the timer thread using communication-pipe (the timer thread
waits this communication-pipe with select(2)).
The discussion about this modification can be found from the post
[ruby-core:33456] and other related posts.
Note that Eric Wong and KOSAKI Motohiro give us the huge
contributions for this modification. Thanks.
* thread_pthread.c (rb_thread_wakeup_timer_thread): add a function.
This function wakes up the timer thread using communication-pipe.
* thread.c (rb_thread_stop_timer_thread): add a parameter which
specify closing communication-pipe or not.
* thread.c (rb_thread_terminate_all): do not stop timer thread here
(ruby_cleanup() terminate timer thread).
* signal.c: wake up timer thread using
rb_thread_wakeup_timer_thread() from signal handler.
* eval.c (ruby_cleanup): use rb_thread_stop_timer_thread(1).
* process.c: use rb_thread_stop_timer_thread(0)
(reuse communication-pipe).
* thread_win32.c (rb_thread_wakeup_timer_thread): add a dummy
function.
* vm_core.h: add and fix decl. of functions.

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]

not by CRITICAL_SECTION but by Mutex.
