* improve handling of timer thread shutdownnormal2015-08-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Shutting down the timer thread now always closes pipes to free FDs. In fact, we close the write ends of the pipes is done in the main RubyVM to signal the timer thread shutdown. To effectively close pipes, we implement userspace locks via atomics to force the pipe closing thread to wait on any signal handlers which may be waking up. While we're at it, improve robustness during resource exhaustion and allow it to limp along non-fatally if restarting a timer thread fails. This reverts r51268 Note: this change is tested with VM_CHECK_MODE 1 in vm_core.h * process.c (close_unless_reserved): add extra check (dup2_with_divert): remove (redirect_dup2): use dup2 without divert (before_exec_non_async_signal_safe): adjust call + comment (rb_f_exec): stop timer thread for all OSes (rb_exec_without_timer_thread): remove * eval.c (ruby_cleanup): adjust call * thread.c (rb_thread_stop_timer_thread): always close pipes * thread_pthread.c (struct timer_thread_pipe): add writing field, mark owner_process volatile for signal handlers (rb_thread_wakeup_timer_thread_fd): check valid FD (rb_thread_wakeup_timer_thread): set writing flag to prevent close (rb_thread_wakeup_timer_thread_low): ditto (CLOSE_INVALIDATE): new macro (close_invalidate): new function (close_communication_pipe): removed (setup_communication_pipe_internal): make errors non-fatal (setup_communication_pipe): ditto (thread_timer): close reading ends inside timer thread (rb_thread_create_timer_thread): make errors non-fatal (native_stop_timer_thread): close write ends only, always, wait for signal handlers to finish (rb_divert_reserved_fd): remove * thread_win32.c (native_stop_timer_thread): adjust (untested) (rb_divert_reserved_fd): remove * vm_core.h: adjust prototype git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51576 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
