use 0 for rb_data_type_t::reserved instead of NULL, since its type
may be changed in the future and possibly not a pointer type.

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?

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.

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.

see #8537.

hook GC invocation.
* ObjectSpace.after_gc_start_hook=(proc)
* ObjectSpace.after_gc_end_hook=(proc)
Note that hooks are not kicked immediately. Procs are kicked
at postponed_job.
This feature is a sample of new internal event and
rb_postponed_job API.

Read the following test to know HOWTO.
This feature is a sample of RUBY_INTERNAL_EVENT.
* test/objspace/test_objspace.rb: add a test.
* ext/objspace/object_tracing.c: ditto.
* gc.c (rb_gc_count): add. THis function returns GC count.
* internal.h: add decl. of rb_gc_count(). Same as `GC.count'.

* ext/objspace/objspace.c (type2sym, count_objects_size): use enum
instead of size_t which may be larger than actual values.

structure of the result of reachable objects. Keys of table
contains object_id of each reachable objects. Value of table
is an object itself or an instance of InternalObjectWrapper.
To avoid duplication, we use st_table and object_id keys.
* ext/objspace/objspace.c (type2sym): bug fix.
Should use `i' instead of `type'.

`ObjectSpace::InternalObjectWrapper#internal_object_id' which returns
an object id of a wrapped internal object.

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.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37307 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
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().
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37094 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
Fix rdoc.
* ext/objspace/objspace.c (ObjectSpace.count_tdata_objects):
Change key type if the klass of a object is zero (internal object).
Read rdoc for details.
* internal.h: export rb_objspace_data_type_name().
