vm.c: suppress warning

2012-12-28T03:03:19+00:00

* vm.c (check_machine_stack_size): ifdef a variable which is unused on
  non-pthread platforms.

git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@38640 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* vm_trace.c (rb_threadptr_exec_event_hooks_and_pop_frame):

2012-12-25T13:24:17+00:00

  pop a frame before JUMP_TAG() if exception occurred.
  This change fix bug of Ruby 1.9.
  [ruby-core:51128] [ruby-trunk - Bug #7624]
* vm_core.h (EXEC_EVENT_HOOK_AND_POP_FRAME): add to use
  `rb_threadptr_exec_event_hooks_and_pop_frame()'.
* vm.c (vm_exec): use EXEC_EVENT_HOOK_AND_POP_FRAME() while
  exception handling. While exception hadnling, if an exception
  is raised in hooks, need to pop current frame and raise this
  raised exception by hook.
* test/ruby/test_settracefunc.rb: add a test.

* vm_core.h, eval_intern.h (CHECK_STACK_OVERFLOW): move

2012-12-25T09:57:07+00:00

  CHECK_STACK_OVERFLOW() to vm_core.h and rename to
  CHECK_VM_STACK_OVERFLOW().
  This change is only move and rename.
* tool/instruction.rb: catch up above changes.
* vm.c, vm_insnhelper.c: ditto.
* vm_insnhelper.c (vm_stackoverflow): add a function to unify
  raising vm stackoverflow exception.

* 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.

* cont.c (rb_fiber_start): in case of jump with TAG_FATAL,

2012-12-22T06:45:28+00:00

  enqueue error into async_errinfo_queue, because you cannot call
  TH_TAG_JUMP() in this function. [ruby-dev:45218]  [Bug #5993]

* thread.c (rb_threadptr_execute_interrupts): now INT2FIX(TAG_FATAL)
  can be popped from async_errinfo_queue.

* vm.c (rb_vm_make_jump_tag_but_local_jump): revert r38441.
  rb_vm_make_jump_tag_but_local_jump() shouldn't return exception
  in case of state == TAG_FATAL.

* test/ruby/test_fiber.rb (test_exit_in_fiber): fix a test to illuminate
  Thread.exit should terminate current Thread.

vm.c: fix format

2012-12-20T01:52:50+00:00

* vm.c (get_param): fix format specifier for size_t.

* 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.

* 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.
