ruby.git/thread_pthread.c, branch v2_0_0_rc1

* configure.in (OBJCOPY): Fixes build error for NativeClient.

2013-01-03T05:46:29+00:00

  Avoid disabling OBJCOPY for NativeClient.

* thread_pthread.c (rb_reserved_fd_p): USE_SLEEPY_TIMER_THREAD is
  always defined.  Fixes compilation error for NativeClient.

* vm.c: support variable VM/Machine stack sizes.

2012-12-19T22:29:18+00:00

  Specified by the following environment variaables:
  - RUBY_THREAD_VM_STACK_SIZE: vm stack size used at thread creation.
  default: 128KB (32bit CPU) or 256KB (64bit CPU).
  - RUBY_THREAD_MACHINE_STACK_SIZE: machine stack size used at thread
  creation. default: 512KB or 1024KB.
  - RUBY_FIBER_VM_STACK_SIZE: vm stack size used at fiber creation.
  default: 64KB or 128KB.
  - RUBY_FIBER_MACHINE_STACK_SIZE: machine stack size used at fiber
  creation. default: 256KB or 256KB.
  This values are specified at launched timing. You can not change
  these values at running time.
  Environ variables are only *hints* because:
  - They are aligned to 4KB.
  - They have minimum values (depend on OSs).
  - Machine stack settings are ignored by some OSs.
  Default values especially fiber stack sizes are increased.
  This change affect Fiber's behavior:
  (1) You can run more complex program on a Fiber.
  (2) You can not make many (thousands) Fibers because of
  lack of address space (on 32bit CPU).
  If (2) bothers you,
  (a) Use 64bit CPU with big memory, or
  (b) Specify RUBY_FIBER_(VM|MACHINE)_STACK_SIZE correctly.
  You need to choose correct stack size carefully. These values
  are completely rely on systems (OS/compiler and so on).
* vm_core.h (rb_vm_t::default_params): add to record above settings.
* vm.c (RubyVM::DEFAULT_PARAMS): add new constant to see
  above setting.
* thread_pthread.c: support RUBY_THREAD_MACHINE_STACK_SIZE.
* cont.c: support RUBY_FIBER_(VM|MACHINE)_STACK_SIZE.
* test/ruby/test_fiber.rb: add tests for above.
* test/ruby/test_thread.rb: ditto.

* thread_pthread.c (rb_reserved_fd_p): fix typo in macro check

2012-11-05T16:43:32+00:00

  that prevented the ifdef ever being true.

* thread_pthread.c (native_thread_init, native_thread_destroy):

2012-11-05T02:46:41+00:00

  removed HAVE_PTHREAD_CONDATTR_INIT check because this silly
  #ifdef makes use-uninitialized-var issue and (2) native_cond_initialize()
  already have a right platform and caller don't need any additional care.

thread_pthread.c: precise stack size

2012-10-04T02:43:30+00:00

* thread_pthread.c (ruby_init_stack): round stack limit to page size
  boundary to calculate stack size more precisely.  [ruby-dev:46174]

thread_pthread.c: init stack with ulimit

2012-10-03T06:33:08+00:00

* thread_pthread.c (ruby_init_stack): use getrlimit() for the main
  thread on Mac OS X, since pthread_get_stack{addr,size}_np() and
  return the default value always, but not the ulimit value.
