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.
A prerequisite to fix https://bugs.ruby-lang.org/issues/15589 with JIT.
This commit alone doesn't make a significant difference yet, but I thought
this commit should be committed independently.
This method override was discussed in [Misc #16961].
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).
The script in prelude.rb was embed in MRI to load it (eval this
script at everyboot).
This commit change the loading process of prelude.rb. MRI doesn't
eval a script, but load from compiled binary with builtin feature.
So that Init_prelude() does not load `prelude.rb` now.
IO#read/write_nonblock methods are defined in prelude.rb with
special private method __read/write_nonblock to reduce keyword
parameters overhead. We can move them into io.rb with builtin
functions.
Support loading builtin features written in Ruby, which implement
with C builtin functions.
[Feature #16254]
Several features:
(1) Load .rb file at boottime with native binary.
Now, prelude.rb is loaded at boottime. However, this file is contained
into the interpreter as a text format and we need to compile it.
This patch contains a feature to load from binary format.
(2) __builtin_func() in Ruby call func() written in C.
In Ruby file, we can write `__builtin_func()` like method call.
However this is not a method call, but special syntax to call
a function `func()` written in C. C functions should be defined
in a file (same compile unit) which load this .rb file.
Functions (`func` in above example) should be defined with
(a) 1st parameter: rb_execution_context_t *ec
(b) rest parameters (0 to 15).
(c) VALUE return type.
This is very similar requirements for functions used by
rb_define_method(), however `rb_execution_context_t *ec`
is new requirement.
(3) automatic C code generation from .rb files.
tool/mk_builtin_loader.rb creates a C code to load .rb files
needed by miniruby and ruby command. This script is run by
BASERUBY, so *.rb should be written in BASERUBY compatbile
syntax. This script load a .rb file and find all of __builtin_
prefix method calls, and generate a part of C code to export
functions.
tool/mk_builtin_binary.rb creates a C code which contains
binary compiled Ruby files needed by ruby command.
* inits.c: call `Init_vm_postponed_job` first because
postponed_job is used by transient heap.

* transient_heap.c, transient_heap.h: implement TransientHeap (theap).
theap is designed for Ruby's object system. theap is like Eden heap
on generational GC terminology. theap allocation is very fast because
it only needs to bump up pointer and deallocation is also fast because
we don't do anything. However we need to evacuate (Copy GC terminology)
if theap memory is long-lived. Evacuation logic is needed for each type.
See [Bug #14858] for details.
* array.c: Now, theap for T_ARRAY is supported.
ary_heap_alloc() tries to allocate memory area from theap. If this trial
sccesses, this array has theap ptr and RARRAY_TRANSIENT_FLAG is turned on.
We don't need to free theap ptr.
* ruby.h: RARRAY_CONST_PTR() returns malloc'ed memory area. It menas that
if ary is allocated at theap, force evacuation to malloc'ed memory.
It makes programs slow, but very compatible with current code because
theap memory can be evacuated (theap memory will be recycled).
If you want to get transient heap ptr, use RARRAY_CONST_PTR_TRANSIENT()
instead of RARRAY_CONST_PTR(). If you can't understand when evacuation
will occur, use RARRAY_CONST_PTR().

An instruction is leaf if it has no rb_funcall inside. In order to
check this property, we introduce stack canary which is a random
number collected at runtime. Stack top is always filled with this
number and checked for stack smashing operations, when VM_CHECK_MODE.

When generate Hash object, the heap area of st_table will be always allocated in internally
and seems it take a time.
To improve performance of creating Hash object,
this patch will reduce count of allocating heap areas for st_table by reuse them.
Performance of creating Hash literal -> 1.53 times faster.
