ruby.git/gc.h, branch v2_1_0_preview2

* gc.h (rb_objspace_reachable_objects_from_root): added.

2013-10-15T10:22:33+00:00

  This API provides information which objects are root objects.
  `category' shows what kind of root objects.
* gc.c (gc_mark_roots): separate from gc_marks_body().

* ext/objspace/objspace.c (ObjectSpace.reachable_objects_from):

2012-10-24T00:04:56+00:00

  internal object support.
  If given object `obj' has references to internal objects
  (such as T_NODE objects), then this method returns instances of
  `ObjectSpace::InternalObjectWrapper' instead of that internal objects.
  This instance contains a refereance to an internal object and you can
  check the type of internal object using
  `ObjectSpace::InternalObjectWrapper#type' method.
  Rdoc of `InternalObjectWrapper' is not prepared yet.
* gc.c (rb_objspace_reachable_objects_from), gc.h: change
  an interface of 'rb_objspace_reachable_objects_from()'
* gc.c, gc.h: add two APIs
  - rb_objspace_markable_object_p(obj): check markable or not.
  - rb_objspace_internal_object_p(obj): check internal or not.

* ext/objspace/objspace.c: add ObjectSpace#reachable_objects_from.

2012-10-05T08:14:09+00:00

  This method returns an array of objects referenced by given object.
  If given object is special objects such as true/false/nil/Fixnum etc
  then it returns nil. See rdoc for details.
  [ruby-core:39772]
* test/objspace/test_objspace.rb: add a test for this method.
* gc.c: add rb_objspace_reachable_objects_from().
  To make this function, add several member `mark_func_data'
  to rb_objspace_t.  If mark_func_data is not null, then
  gc_mark() calls mark_func_data::mark_func.
* gc.h: export rb_objspace_reachable_objects_from().

Imports Ruby's port to NativeClient (a.k.a NaCl).

Patch by Google Inc. [ruby-core:45073].

* configure.in (RUBY_NACL): New M4 func to configure variables for
  NaCl.
  (RUBY_NACL_CHECK_PEPPER_TYPES): New M4 func to check the old names
  of Pepper interface types.
  (BTESTRUBY): New variable to specify which ruby should be run on
  "make btest". NaCl can run the built binary by sel_ldr, but it need
  rbconfig.rb. So this variable is distinguished from $MINIRUBY.
  
* thread_pthread.c: Disabled some features on NaCl.

* io.c: ditto.

* process.c: ditto.

* signal.c: ditto.

* file.c: ditto.

* missing/flock.c: ditto.

* nacl/pepper_main.c: An example implementation of Pepper application
  that embeds Ruby.

* nacl/example.html: An example of web page that uses the Pepper
  application.

* nacl/nacl-config.rb: Detects variants of NaCl SDK.

* nacl/GNUmakefile.in: Makefile template for NaCl specific build
  process.

* nacl/package.rb: script for packaging a NaCl-Ruby embedding
  application. 

* nacl/reate_nmf.rb: Wrapper script of create_nmf.py

* dln.c (dln_load): Added a hack to call on NaCl.

* util.c (ruby_getcwd): Path to the current directort is not available
  on NaCl.
