* thread.c: rename methods:

2012-12-23T10:18:58+00:00

  from Thread.async_interrupt_timing to Thread.handle_interrupt,
  from Thread.async_interrupted? to Thread.pending_interrupt?.
  Also rename option from `defer' to `never'.
  [ruby-core:51074] [ruby-trunk - Feature #6762]
* vm_core.c, thread.c: rename functions and data structure
  `async_errinfo' to `pending_interrupt'.
* thread.c: add global variables sym_immediate, sym_on_blocking and
  sym_never.
* cont.c, process.c, vm.c, signal.c: ditto.
* lib/sync.rb, lib/thread.rb: catch up this renaming.
* test/ruby/test_thread.rb: ditto.

* signal.c (rb_sigaltstack_size): cast sysconf() return value

2012-12-15T17:10:50+00:00

  explicitly. Fix compile error on Mac OS X.

  call. sigaltstack was already registered when creating threads.

* signal.c (rb_sigaltstack_size): new. calculate stack size for

2012-12-15T14:20:12+00:00

  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.

* signal.c (rb_register_sigaltstack): replace ALT_STACK_SIZE with
  rb_sigaltstack_size();
* gc.c (Init_heap): ditto.
* vm.c (th_init): ditto.

* signal.c (rb_f_kill): remove rb_thread_polling() because this

2012-12-14T15:11:59+00:00

  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]

* ruby_atomic.h (ATOMIC_CAS): added for Solaris and other platforms.

2012-11-27T10:21:59+00:00

* ruby_atomic.h, signal.c (NEED_RUBY_ATOMIC_OPS): renamed from
  NEED_RUBY_ATOMIC_EXCHANGE.
* signal.c (ruby_atomic_compare_and_swap): naive, non-atomic
  compare-and-swap implementation only used for platforms without
  valid support for atomic operations.
