This commit introduces Ractor mechanism to run Ruby program in
parallel. See doc/ractor.md for more details about Ractor.
See ticket [Feature #17100] to see the implementation details
and discussions.
[Feature #17100]
This commit does not complete the implementation. You can find
many bugs on using Ractor. Also the specification will be changed
so that this feature is experimental. You will see a warning when
you make the first Ractor with `Ractor.new`.
I hope this feature can help programmers from thread-safety issues.
Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).
Currently we are not able to grab the correct end/top of the stack on
powerpc64 due to the fact that it uses the fallback function.
The fallback function does not return the correct top of the stack
because it adds a new frame and the returned top of the stack contains
this frame overhead that could be something around 112 bytes on
Powerpc64.
This patch simply gets the correct top of the stack pointer, which is
always on r1 register according to both ABI v1 and ABI v2 (Little
endian).

Renaming this function. "No pin" leaks some implementation details. We
just want users to know that if they mark this object, the reference may
move and they'll need to update the reference accordingly.
debug utility macro rp() (rp_m()) and bp() are introduced.
* rp(obj) shows obj information w/o any side-effect to STDERR.
* rp_m(m, obj) is similar to rp(obj), but show m before.
* bp() is alias of ruby_debug_breakpoint(), which is registered
as a breakpoint in run.gdb (used by `make gdb` or make gdb-ruby`).
`transient_heap_evacuate()` disables GC using `rb_gc_disable()`
to prohibt GC invocation because of new allocation for evacuated
memory. However, `rb_gc_disable()` sweep all rest of unswept pages.
We don't need to cancel lazy sweep so this patch introduce
`rb_gc_disable_no_rest()` which doesn't cancel lazy sweep.
For some reason symbols (or classes) are being overridden in trunk

Add a new (hidden) C-API to iterate objspace snapshot.
This API is not safe to call any C-APIs in a given callback
function. Be careful to use this C-API.

This function *ONLY* works just after marking phase,
before any sweeping.
This function is highly depending current GC implementation
and can be removed future version.

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().

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().
