vm_trace.c: isolate errinfo in trace blocks

2013-11-07T00:39:56+00:00

* vm_trace.c (rb_threadptr_exec_event_hooks_orig): errinfo should not
  be propagated to trace blocks so that no argument raise does not
  throw internal objects.  [ruby-dev:47793] [Bug #9088]

* add RUBY_TYPED_FREE_IMMEDIATELY to data types which only use

2013-10-29T11:16:54+00:00

  safe functions during garbage collection such as xfree().
  On default, T_DATA objects are freed at same points as fianlizers.
  This approach protects issues such as reported by [ruby-dev:35578].
  However, freeing T_DATA objects immediately helps heap usage.
  Most of T_DATA (in other words, most of dfree functions) are safe.
  However, we turned off RUBY_TYPED_FREE_IMMEDIATELY by default
  for safety.

* vm_trace.c (tp_free): remvoed because empty free function.

2013-10-29T09:47:06+00:00

  Use RUBY_TYPED_NEVER_FREE instead.

* vm_trace.c: exterminate Zombies.

2013-10-22T06:24:54+00:00

  There is a bug that T_ZOMBIE objects are not collected.
  Because there is a pass to miss finalizer postponed job
  with multi-threading. This patch solve this issue.
* vm_trace.c (rb_postponed_job_register_one): set
  RUBY_VM_SET_POSTPONED_JOB_INTERRUPT(th) if another same job
  is registered.
  There is a possibility to remain a postponed job without
  interrupt flag.
* vm_trace.c (rb_postponed_job_register_one): check interrupt
  carefully.
* vm_trace.c (rb_postponed_job_register_one): use additional space
  to avoid buffer full.
* gc.c (gc_finalize_deferred_register): check failure.
* thread.c (rb_threadptr_execute_interrupts): check
  `postponed_job_interrupt' immediately.  There is a possibility
  to miss this flag.
