| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | * 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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@32345 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* * thread_pthread.c: Stop polling in the timer thread when there areko12011-06-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@32244 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
