thread_pthread.c: check stack on co-routine case

2016-09-03T02:28:31+00:00

* thread_pthread.c (ruby_init_stack): check stack bounds even if
  get_main_stack succeeded, on the "co-routine" case.

thread_pthread.c: no fork, no gvl_atfork

2016-05-20T14:24:39+00:00

* thread_pthread.c (gvl_atfork): used in rb_thread_atfork_internal
  only if HAVE_WORKING_FORK is defined.

thread_pthread.c (rb_thread_create_timer_thread): fix race

2015-12-29T18:20:27+00:00

This fixes an occasional [ASYNC BUG] failure in
bootstraptest/test_fork.rb '[ruby-dev:37934]'
which tests fork/pthread_create failure by setting
RLIMIT_NPROC to 1 and triggering EAGAIN on pthread_create
when attempting to recreate the timer thread.

The problem timeline is as follows:

thread 1                           thread 2
---------------------------------------------------------------
rb_thread_create_timer_thread
setup_communication_pipe
                                   rb_thread_wakeup_timer_thread_low
pthread_create fails               pipe looks valid, write!
CLOSE_INVALIDATE (x4)              EBADF -> ASYNC BUG

The checks in rb_thread_wakeup_timer_thread_low only tried to
guarantee proper ordering with native_stop_timer_thread, not
rb_thread_create_timer_thread :x

Now, this should allow rb_thread_create_timer_thread to
synchronize properly with rb_thread_wakeup_timer_thread_low by
delaying the validation marking of the timer_thread_pipe until
we are certain the timer thread is alive.

In this version, rb_thread_wakeup_timer_thread_low becomes a
noop.  Threading is still completely broken with NPROC==1, but
there's not much we can do about it beside warn the user.
We no longer spew a scary [ASYNC BUG] message or dump core
on them.

* thread_pthread.c (setup_communication_pipe): delay setting owner

configure.in: split SET_THREAD_NAME

2015-12-03T02:57:14+00:00
