Method#call, UnboundMethod#bind_call
Also add keyword argument separation warnings for Class#new and Method#call.
To allow for keyword argument to required positional hash converstion in
cfuncs, add a vm frame flag indicating the cfunc was called with an empty
keyword hash (which was removed before calling the cfunc). The cfunc can
check this frame flag and add back an empty hash if it is passing its
arguments to another Ruby method. Add rb_empty_keyword_given_p function
for checking if called with an empty keyword hash, and
rb_add_empty_keyword for adding back an empty hash to argv.
All of this empty keyword argument support is only for 2.7. It will be
removed in 3.0 as Ruby 3 will not convert empty keyword arguments to
required positional hash arguments. Comment all of the relevent code
to make it obvious this is expected to be removed.
Add rb_funcallv_kw as an public C-API function, just like rb_funcallv
but with a keyword flag. This is used by rb_obj_call_init (internals
of Class#new). This also required expected call_type enum with
CALL_FCALL_KW, similar to the recent addition of CALL_PUBLIC_KW.
Add rb_vm_call_kw as a internal function, used by call_method_data
(internals of Method#call and UnboundMethod#bind_call). Add tests
for UnboundMethod#bind_call keyword handling.

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.
|
|
Requested by ko1. Also, because now that this function is internal
use only, why not just directly use struct rb_call_cache to purge
the ZALLOC.
|
|
Add rb_keyword_given_p to the C-API

consistent with the definition
|
|
This syntax means the method should be treated as a method that
uses keyword arguments, but no specific keyword arguments are
supported, and therefore calling the method with keyword arguments
will raise an ArgumentError. It is still allowed to double splat
an empty hash when calling the method, as that does not pass
any keyword arguments.

After 5e86b005c0f2ef30df2f9906c7e2f3abefe286a2, I now think ANYARGS is
dangerous and should be extinct. This commit deletes ANYARGS from
rb_thread_create, which seems very safe to do.

After 5e86b005c0f2ef30df2f9906c7e2f3abefe286a2, I now think ANYARGS is
dangerous and should be extinct. This commit deletes ANYARGS from
struct vm_ifunc, but in doing so we also have to decouple the usage
of this struct in compile.c, which (I think) is an abuse of ANYARGS.

VM_DEBUG_MODE has been used only here.

And pass rb_execution_context_t as an argument.

This reverts commit 9faef3113fb4331524b81ba73005ba13fa0ef6c6.
It seemed to cause a failure on macOS Mojave, though I'm unsure how.
https://rubyci.org/logs/rubyci.s3.amazonaws.com/osx1014/ruby-master/log/20190802T034503Z.fail.html.gz
This tentative revert is to check if the issue is actually caused by the
change or not.

This commit adds a specialized instruction for called to `.nil?`. It is
about 27% faster than master in the case where the object is nil or not
nil. In the case where an object implements `nil?`, I think it may be
slightly slower. Here is a benchmark:
```ruby
require "benchmark/ips"
class Niller
def nil?; true; end
end
not_nil = Object.new
xnil = nil
niller = Niller.new
Benchmark.ips do |x|
x.report("nil?") { xnil.nil? }
x.report("not nil") { not_nil.nil? }
x.report("niller") { niller.nil? }
end
```

If `vm_stack` is left dangling in a forked process, the gc attempts to scan
it, but it is invalid and will cause a segfault. Therefore, we clear it
before forking.
In order to simplify this, `rb_ec_clear_vm_stack` was introduced.

This commit adds compaction support for:
* Fibers
* Continuations
* Autoload Constants
|
|
It seems sanitizers require extra amount of machine stacks. Without
extending them the process tends to stack overflow.
|
|
Before this commit, classes and modules would be registered with the
VM's `defined_module_hash`. The key was the ID of the class, but that
meant that it was possible for hash collisions to occur. The compactor
doesn't allow classes in the `defined_module_hash` to move, but if there
is a conflict, then it's possible a class would be removed from the hash
and not get pined.
This commit changes the key / value of the hash just to be the class
itself, thus preventing movement.

cfp->bp was (re-)introduced by Kokubun san, but VM doesn't use it
because I (ko1) want to remove it in a future. But using it make
leave instruction fast because of sp consisntency check.
So now VM uses cfp->bp.
To use cfp->bp, I checked the value and I found that it is not a
"initial value of sp" but a "initial value of ep". Fix this problem
and fix all bp references (this is why bp is renamed to bp_).

[Fix GH-2099]

zlib and bignum both contain unblocking functions which are
async-signal-safe and do not require spawning additional
threads.
We can execute those functions directly in signal handlers
without incurring overhead of extra threads, so provide C-API
users the ability to deal with that. Other C-API users may
have similar need.
This flexible API can supercede existing uses of
rb_thread_call_without_gvl and rb_thread_call_without_gvl2 by
introducing a flags argument to control behavior.
Note: this API is NOT finalized. It needs approval from other
committers. I prefer shorter name than previous
rb_thread_call_without_gvl* functions because my eyes requires
big fonts.

objects and return same ISeq object for an internal ISeq object.
* iseq.h (ISEQ_EXECUTABLE_P): introduced to check executable ISeq objects.
* iseq.h (ISEQ_COMPILE_DATA_ALLOC): reordr setting flag line to avoid
ISEQ_USE_COMPILE_DATA but compiled_data == NULL case.
* vm_core.h (rb_iseq_t): introduce `rb_iseq_t::wrapper` and
`rb_iseq_t::aux::exec`. Move `rb_iseq_t::local_hooks` to
`rb_iseq_t::aux::exec::local_hooks`.
* test/ruby/test_iseq.rb: add ISeq.of() tests.

* vm_trace.c (rb_tracepoint_enable_for_target): support targetting
TracePoint. [Feature #15289]
Tragetting TracePoint is only enabled on specified method, proc
and so on, example: `tp.enable(target: code)`.
`code` should be consisted of InstructionSeuqnece (iseq)
(RubyVM::InstructionSeuqnece.of(code) should not return nil)
If code is a tree of iseq, TracePoint is enabled on all of
iseqs in a tree.
Enabled tragetting TracePoints can not enabled again with
and without target.
* vm_core.h (rb_iseq_t): introduce `rb_iseq_t::local_hooks`
to store local hooks.
`rb_iseq_t::aux::trace_events` is renamed to
`global_trace_events` to contrast with `local_hooks`.
* vm_core.h (rb_hook_list_t): add `rb_hook_list_t::running`
to represent how many Threads/Fibers are used this list.
If this field is 0, nobody using this hooks and we can
delete it.
This is why we can remove code from cont.c.
* vm_core.h (rb_vm_t): because of above change, we can eliminate
`rb_vm_t::trace_running` field.
Also renamed from `rb_vm_t::event_hooks` to `global_hooks`.
* vm_core.h, vm.c (ruby_vm_event_enabled_global_flags): renamed
from `ruby_vm_event_enabled_flags.
* vm_core.h, vm.c (ruby_vm_event_local_num): added to count
enabled targetting TracePoints.
* vm_core.h, vm_trace.c (rb_exec_event_hooks): accepts
hook list.
* vm_core.h (rb_vm_global_hooks): added for convinience.
* method.h (rb_method_bmethod_t): added to maintain Proc
and `rb_hook_list_t` for bmethod (defined by define_method).
* prelude.rb (TracePoint#enable): extracet a keyword parameter
(because it is easy than writing in C).
It calls `TracePoint#__enable` internal method written in C.
* vm_insnhelper.c (vm_trace): check also iseq->local_hooks.
* vm.c (invoke_bmethod): check def->body.bmethod.hooks.
* vm.c (hook_before_rewind): check iseq->local_hooks
and def->body.bmethod.hooks before rewind by exception.

penalty for modern compilers; this adds type-checking, too.

* vm_core.h: remove `rb_execution_context_t::passed_bmethod_me`
and fix functions to pass the `me` directly.
`passed_bmethod_me` was used to make bmethod (methods defined by
`defined_method`). `rb_vm_invoke_bmethod` invoke `Proc` with `me`
information as method frame (`lambda` frame, actually).
If the proc call is not bmethod call, `passed_bmethod_me` should
be NULL. However, there is a bug which passes wrong `me` for
normal block call.
http://ci.rvm.jp/results/trunk-asserts@silicon-docker/1449470
This is because wrong `me` was remained in `passed_bmethod_me`
(and used incorrectly it after collected by GC).
We need to clear `passed_bmethod_me` just after bmethod call,
but clearing is not enough.
To solve this issue, I removed `passed_bmethod_me` and pass `me`
information as a function parameter of `rb_vm_invoke_bmethod`,
`invoke_block_from_c_proc` and `invoke_iseq_block_from_c` in vm.c.
* vm.c (invoke_iseq_block_from_c): the number of parameters is too
long so that I try to specify `ALWAYS_INLINE`.
* vm.c (invoke_block_from_c_proc): ditto.
* vm_insnhelper.c (vm_yield_with_cfunc): now there are no pathes
to use bmethod here.

* vm_core.h (rb_thread_struct): introduce new fields `invoke_type`
and `invoke_arg`.
There are two types threads: invoking proc (normal Ruby thread
created by `Thread.new do ... end`) and invoking func, created
by C-API. `invoke_type` shows the types.
* thread.c (thread_do_start): copy `invoke_arg.proc.args` contents
from Array to ALLOCA stack memory if args length is enough small (<8).
We don't need to keep Array and don't need to cancel using transient heap.
* vm.c (thread_mark): For func invoking threads, they can pass (void *)
parameter (rb_thread_t::invoke_arg::func::arg). However, a rubyspec test
(thread_spec.c) passes an Array object and it expect to mark it.
Clealy it is out of scope (misuse of `rb_thread_create` C-API). However,
I'm not sure someone else has such kind of misunderstanding.
So now we mark conservatively this (void *) arg with rb_gc_mark_maybe.
This misuse is found by this error log.
