kosaki 44b4b9060d * signal.c (rb_sigaltstack_size): cast sysconf() return value
explicitly. Fix compile error on Mac OS X.

git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@38415 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-12-15 17:10:50 +00:00
kosaki 0e19d2b434 * signal.c (default_handler): remove rb_register_sigaltstack()
call. sigaltstack was already registered when creating threads.

kosaki aff9dff46d * signal.c (rb_sigaltstack_size): new. calculate stack size for
sigsegv handler. enlarge value when x86 or x86_64 on Linux.
  Linux has very small MINSIGSTKSZ size (2048 bytes) and
  our sigsegv routine need 5KiB at least. [Bug #7141]
* internal.h: add declaration of rb_sigaltstack_size().
* vm_core.h: remove ALT_STACK_SIZE definition.

2012-12-15 14:20:12 +00:00
kosaki cb92817e7c * signal.c (rb_f_kill): remove rb_thread_polling() because this
has no good effect and makes meaningless 100ms delay. 1)
  when sending signal to another process, waiting has just silly.
  2) when sending signal to current process, 100ms is often not
  enough time to wait. It depend on kernel behavior. And,
  rb_thread_polling() doesn't make sense anyway. When rb_thread_alone()
  is true, it doesn't wait at all and Process.kill() users don't
  expect threading changes Process.kill() behavior. [Bug #7560]

kosaki 2acd61551b * signal.c (sigsegv): use abort() instead of exit() when nested
SEGV was happen. Because unnested SEGV use abort().

kosaki 5a73c71dcf * thread_pthread.c (get_stack): add to a care of gurad page on Mac
OS X. [Bug #1813] [ruby-core:24540]
* signal.c (ruby_signal): SIGBUS use alternative stack too.
* signal.c (sigbus): On Mac, thread stack overflow makes SIGBUS
  instead of SIGSEGV. thus, added stackoverflow check.
* signal.c (default_handler): get rid of compilation warning.
* signal.c (Init_signal): ditto.

ko1 fa4514e4fe * thread.c (rb_threadptr_check_signal): only wake up main thread.
* thread.c (rb_threadptr_execute_interrupts_common): check signal
  deliverly if it is main thread.
  fixes [ruby-dev:44005] [Ruby 1.9 - Bug #4950]
* bootstraptest/test_fork.rb: add a test for above.
* signal.c (rb_get_next_signal): skip if signal_buff is empty.
  (check signal_buff.size first)
* vm_core.h: remove unused variable rb_thread_t::exec_signal.
* thread.c (rb_thread_check_trap_pending): check
  rb_signal_buff_size() because rb_thread_t::exec_signal
  is no longer available.

kosaki 0148d41a13 * signal.c: Now, USE_TRAP_SIGMASK depend on HAVE_PTHREAD_SIGMASK.
The code have already depended on pthread_sigmask since r27464.

ko1 d1d5d5e798 * thread_pthread.c: Stop polling in the timer thread when there are
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.

kosaki 9d4e471cf9 * vm_core.h (RUBY_VM_SET_TIMER_INTERRUPT, RUBY_VM_SET_INTERRUPT,
RUBY_VM_SET_FINALIZER_INTERRUPT): use atomic ops for preventing
  interrupt_flag bit lost.
* thread.c (rb_threadptr_execute_interrupts_rec): ditto.
* vm_core.h (typedef struct rb_thread_struct): change type of
  interrupt_flag to rb_atomic_t.
* atomic.h: move atomic ops definition from signal.c.
* signal.c: remove atomic ops definition.
* common.mk (gc, signal, thread, cont): add to dependency to atomic.h.

  for send signal to process group.
