  compare_by_identity hash to avoid hash modify problem
  during iteration.
  [Bug #9252]

* ext/objspace/objspace.c (reachable_object_from_root_i):

2013-12-15T04:42:23+00:00

  reachable objects should not include categories and
  category_objects because it is noisy information.
  In fact, objects created after calling
  ObjectSpace.reachable_objects_from_root should not be included
  as a returning hash objects. Currently, mswin64 platform has a
  problem because of this behaviour. Should we trace new objects?

* ext/objspace/object_tracing.c: Add experimental methods to dump

2013-11-08T17:06:55+00:00

objectspace as json: ObjectSpace.dump_all and ObjectSpace.dump(obj).
These methods are useful for debugging reference leaks and memory growth
in large ruby applications. [Bug #9026] [ruby-core:57893] [Fixes GH-423]

* gc.c: add support to estimate increase of oldspace memory usage.

2013-11-05T04:51:01+00:00

  This is another approach to solve an issue discussed at r43530.
  This feature is diabled as default.
  This feature measures an increment of memory consuption by oldgen
  objects. It measures memory consumption for each objects when
  the object is promoted. However, measurement of memory consumption
  is not accurate now. So that this measurement is `estimation'.
  To implement this feature, move memsize_of() function from
  ext/objspace/objspace.c and expose rb_obj_memsize_of().
  Some memsize() functions for T_DATA (T_TYPEDDATA) have problem to
  measure memory size, so that we ignores T_DATA objects now.
  For example, some functions skip NULL check for pointer.
  The macro RGENGC_ESTIMATE_OLDSPACE enables/disables this feature,
  and turned off as default.
  We need to compare 3gen GC and this feature carefully.
  (it is possible to enable both feature)
  We need a help to compare them.
* internal.h: expose rb_obj_memsize_of().
* ext/objspace/objspace.c: use rb_obj_memsize_of() function.
* cont.c (fiber_memsize): fix to check NULL.
* variable.c (autoload_memsize): ditto.
* vm.c (vm_memsize): ditto.

* 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.

* ext/objspace/objspace.c: add a new method `reachable_objects_from_root'.

2013-10-16T06:13:41+00:00

  ObjectSpace.reachable_objects_from_root returns all objects refered
  from root (called "root objects").
  This feature is for deep object analysis.
* test/objspace/test_objspace.rb: add a test.
