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.

This removes the warnings added in 2.7, and changes the behavior
so that a final positional hash is not treated as keywords or
vice-versa.
To handle the arg_setup_block splat case correctly with keyword
arguments, we need to check if we are taking a keyword hash.
That case didn't have a test, but it affects real-world code,
so add a test for it.
This removes rb_empty_keyword_given_p() and related code, as
that is not needed in Ruby 3. The empty keyword case is the
same as the no keyword case in Ruby 3.
This changes rb_scan_args to implement keyword argument
separation for C functions when the : character is used.
For backwards compatibility, it returns a duped hash.
This is a bad idea for performance, but not duping the hash
breaks at least Enumerator::ArithmeticSequence#inspect.
Instead of having RB_PASS_CALLED_KEYWORDS be a number,
simplify the code by just making it be rb_keyword_given_p().

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).

Fiber#transfer prevents calling Fiber#resume on the receiver of the
transfer method, not the fiber calling transfer.
Transfering back to a fiber does not allow later calling resume on
the fiber. Once transfer has been called on a fiber, you can never
call resume on the fiber.
Calling resume on a transferred fiber is not a double resume error,
it is a different FiberError (cannot resume transferred Fiber).
For details on the differences between transferred fibers and
regular fibers, see Sasada-san's RubyKaigi 2017 presentation (in
short, Fiber#transfer is for coroutine, Fiber#resume is for
semi-coroutine).

If a fiber is invoked with transfer method (such as "f.transfer"),
then the invoked fiber ("f") is labeled as "transferred" and this
fiber can not be invoked with Fiber#resume. This patch adds
transferred attribute for "Fiber#to_s" (and inspect).

Fiber#transfer previously made it impossible to resume the fiber
if it was transferred to (no resuming the target of Fiber#transfer).
However, the documentation specifies that you cannot resume a fiber
that has transferred to another fiber (no resuming the source of
Fiber#transfer), unless control is transferred back.
Fix the code by setting the transferred flag on the current/source
fiber, and unsetting the transferred flag on the target fiber.

We are calling this in a few other files, it is better to have it
in a header than adding prototypes to the other files.

I've been compiling with:
```
set -lx cflags '-std=c99 -Werror=pedantic -pedantic-errors'
```
But compilation would fail with the following:
```
cont.c:296:90: error: format specifies type 'void *' but the argument has type 'struct fiber_pool_stack *' [-Werror,-Wformat-pedantic]
if (DEBUG) fprintf(stderr, "fiber_pool_stack_alloca(%p): %"PRIuSIZE"/%"PRIuSIZE"\n", stack, offset, stack->available);
~~ ^~~~~
cont.c:467:24: error: format specifies type 'void *' but the argument has type 'struct fiber_pool *' [-Werror,-Wformat-pedantic]
count, fiber_pool, fiber_pool->used, fiber_pool->count, size, fiber_pool->vm_stack_size);
^~~~~~~~~~
cont.c:588:83: error: format specifies type 'void *' but the argument has type 'struct fiber_pool_vacancy *' [-Werror,-Wformat-pedantic]
if (DEBUG) fprintf(stderr, "fiber_pool_stack_acquire: %p used=%"PRIuSIZE"\n", fiber_pool->vacancies, fiber_pool->used);
~~ ^~~~~~~~~~~~~~~~~~~~~
cont.c:736:76: error: format specifies type 'void *' but the argument has type 'rb_fiber_t *' (aka 'struct rb_fiber_struct *')
[-Werror,-Wformat-pedantic]
if (DEBUG) fprintf(stderr, "fiber_stack_release: %p, stack.base=%p\n", fiber, fiber->stack.base);
```
This commit just fixes the pedantic errors

I think this is easier to read than using literal 0 with comments
in every case where it is used.

The kw_splat flag is whether the original call passes keyword or not.
Some types of methods (e.g., bmethod and sym_proc) drops the
information. This change tries to propagate the flag to the final
callee, as far as I can.

After 5e86b005c0f2ef30df2f9906c7e2f3abefe286a2, I now think ANYARGS is
dangerous and should be extinct. This commit deletes ANYARGS from
rb_proc_new / rb_fiber_new, and applies RB_BLOCK_CALL_FUNC_ARGLIST
wherever necessary.

(#2170)
https://github.com/ruby/ruby/pull/2170#issuecomment-489880700
Documentation is for those who don't know, remember, or understand (to any degree) the language, it should attempt to be clear above all other things. The example given is needlessly unclear because if you use a block it's common for arguments to be reused on every entry to the block. In Fiber's case this is not so.
First time round 10 goes in, 12 comes out.
Second time round 14 goes in, 14 comes out… was that because 14 is 12 + 2 or because it's "the return value of the call to Fiber.yield". It's the latter because it says so but why does the example need to make anyone think the former?
Using different numbers makes it immediately clear what's happening whether the description is there or not.

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.

"Therefore, `fiber_pool_stack_free(&vacancy->stack)` can do the wrong
thing..." should be "... `fiber_pool_stack_free(stack)` ...".
|
|
|
|
|
|
|
|
|
| |
After calling `fiber_pool_vacancy_reset`, `vacancy->stack` and `stack` are
no longer in sync. Therefore, `fiber_pool_stack_free(&vacancy->stack)` can
do the wrong thing and clobber the vacancy data.
Additionally, when testing using VM_CHECK_MODE > 0, use MADV_DONTNEED if
possible, to catch issues w.r.t. clobbered vacancy data earlier.

fiber->cont.saved_ec.cfp should be initialized by NULL
because no vm_stack is allocated. However, cont_init()
captures current Fiber's cfp for continuation, so it should
only initialize fibers.

This reverts commit d7fdf45a4ae1bcb6fac30a24b025d4f20149ba0a.

`cont_init` didn't initialize `cont->saved_ec.cfp`. Calling `cont_mark`
would result in an invalid `cfp` in `rb_execution_context_mark`. Because
fibers lazy-initialize the stack, fibers that are created but not resumed
could cause this problem to occur.

If `mmap` fails to allocate memory, try half the size, and so on.
Limit FIBER_POOL_ALLOCATION_MAXIMUM_SIZE to 1024 stacks. In typical
configurations this limits the memory mapped region to ~128MB per
allocation.
