	* iseq.c (rb_iseq_clone): Should not insert write barrier from
	  non-RVALUE data (to non-RVALUE data, of course).
	  Ruby 2.1 also has a same problem.

	test_method.rb, test_proc.rb: suppress warnings

	* test/ruby/test_method.rb: suppress warnings in verbose mode.

	* test/ruby/test_proc.rb: ditto.
	* proc.c (rb_iseq_min_max_arity): maximum argument is unlimited if
	  having rest keywords argument.  [ruby-core:53298] [Bug #8072]

	* iseq.c (rb_iseq_parameters): push argument type symbol only for
	  unnamed rest keywords argument.

	* compile.c (iseq_set_arguments): set arg_keyword_check from
	  nd_cflag, which is set by parser.  internal ID is used for
	  unnamed keyword rest argument, which should be separated from no
	  keyword check.

	* iseq.c (rb_iseq_parameters): if no keyword check, keyword rest is
	  present.

	* parse.y (new_args_tail_gen): set keywords check to nd_cflag, which
	  equals to that keyword rest is not present.

* 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_backtrace.c, include/ruby/debug.h: add new APIs

2013-10-08T12:08:20+00:00

* VALUE rb_profile_frame_method_name(VALUE frame)
* VALUE rb_profile_frame_qualified_method_name(VALUE frame)
* iseq.c (rb_iseq_klass), internal.h: add new internal function
  rb_iseq_method_name().
* ext/-test-/debug/profile_frames.c (profile_frames),
  test/-ext-/debug/test_profile_frames.rb: add a test.

* include/ruby/debug.h: add backtrace collecting APIs for profiler.

2013-10-07T07:21:11+00:00

* int rb_profile_frames(int start, int limit, VALUE *buff, int *lines);
  Collect information of frame information.
* VALUE rb_profile_frame_path(VALUE frame);
* VALUE rb_profile_frame_absolute_path(VALUE frame);
* VALUE rb_profile_frame_label(VALUE frame);
* VALUE rb_profile_frame_base_label(VALUE frame);
* VALUE rb_profile_frame_first_lineno(VALUE frame);
* VALUE rb_profile_frame_classpath(VALUE frame);
* VALUE rb_profile_frame_singleton_method_p(VALUE frame);
  Get information about each frame.
  These APIs are designed for profilers, for example, no objectallocation,
  and enough information for profilers.
  In this version, this API collects only collect Ruby level frames.
  This issue will be fixed after Ruby 2.1.
* vm_backtrace.c: implement above APIs.
* iseq.c (rb_iseq_klass): return local_iseq's class.
