This reverts commits: 10d6a3aca7 8ba48c1b85 fba8627dc1 dd883de5ba
6c6a25feca 167e6b48f1 7cb96d41a5 3207979278 595b3c4fdd 1521f7cf89
c11c5e69ac cf33608203 3632a812c0 f56506be0d 86427a3219 .
The reason for the revert is that we observe ABA problem around
inline method cache. When a cache misshits, we search for a
method entry. And if the entry is identical to what was cached
before, we reuse the cache. But the commits we are reverting here
introduced situations where a method entry is freed, then the
identical memory region is used for another method entry. An
inline method cache cannot detect that ABA.
Here is a code that reproduce such situation:
```ruby
require 'prime'
class << Integer
alias org_sqrt sqrt
def sqrt(n)
raise
end
GC.stress = true
Prime.each(7*37){} rescue nil # <- Here we populate CC
class << Object.new; end
# These adjacent remove-then-alias maneuver
# frees a method entry, then immediately
# reuses it for another.
remove_method :sqrt
alias sqrt org_sqrt
end
Prime.each(7*37).to_a # <- SEGV
```

Now that we have eliminated most destructive operations over the
rb_method_entry_t / rb_callable_method_entry_t, let's make them
mostly immutabe and mark them const.
One exception is rb_export_method(), which destructively modifies
visibilities of method entries. I have left that operation as is
because I suspect that destructiveness is the nature of that
function.

Tired of rb_method_entry_create(..., rb_method_definition_create(
..., &(rb_method_foo_t) {...})) maneuver. Provide a function that
does the thing to reduce copy&paste.

The deleted function was to destructively overwrite existing method
entries, which is now considered to be a bad idea. Delete it, and
assign a newly created method entry instead.

Before this changeset rb_method_definition_create only allocated a
memory region and we had to destructively initialize it later.
That is not a good design so we change the API to return a complete
struct instead.

Most (if not all) of the fields of rb_method_definition_t are never
meant to be modified once after they are stored. Marking them const
makes it possible for compilers to warn on unintended modifications.

VM_NO_KEYWORDS was introduced first in vm_core.h, but it is best
to only use a single definition for this.
|
|
This fixes instance_exec and similar methods. It also fixes
Enumerator::Yielder#yield, rb_yield_block, and a couple of cases
with Proc#{<<,>>}.
This support requires the addition of rb_yield_values_kw, similar to
rb_yield_values2, for passing the keyword flag.
Unlike earlier attempts at this, this does not modify the rb_block_call_func
type or add a separate function type. The functions of type
rb_block_call_func are called by Ruby with a separate VM frame, and we can
get the keyword flag information from the VM frame flags, so it doesn't need
to be passed as a function argument.
These changes require the following VM functions accept a keyword flag:
* vm_yield_with_cref
* vm_yield
* vm_yield_with_block
Notes:

This requires adding rb_proc_call_kw to pass the keyword flag.

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.

It is not safe to set this in C functions that can be called from
other C functions, as in the non argument-delegation case, you
can end up calling a Ruby method with a flag indicating keywords
are set without passing keywords.
Introduce some new *_kw functions that take a kw_splat flag and
use these functions to set RB_PASS_CALLED_KEYWORDS in places where
we know we are delegating methods (e.g. Class#new, Method#call)
|
|
Remove rb_add_empty_keyword, and instead of calling that every
place you need to add empty keyword hashes, run that code in
a single static function in vm_eval.c.
Add 4 defines to include/ruby/ruby.h, these are to be used as
int kw_splat values when calling the various rb_*_kw functions:
RB_NO_KEYWORDS :: Do not pass keywords
RB_PASS_KEYWORDS :: Pass final argument (which should be hash) as keywords
RB_PASS_EMPTY_KEYWORDS :: Add an empty hash to arguments and pass as keywords
RB_PASS_CALLED_KEYWORDS :: Passes same keyword type as current method was
called with (for method delegation)
rb_empty_keyword_given_p needs to stay. It is required if argument
delegation is done but delayed to a later point, which Enumerator
does.
Use RB_PASS_CALLED_KEYWORDS in rb_call_super to correctly
delegate keyword arguments to super method.

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.
|
|
This wraps iseq_location and should fix the leaked global test.
|
|
This shows locations in places it didn't before, such as for
proc calls, and fixes the location for super calls.
This requires making iseq_location non-static and MJIT exported,
which I hope will not cause problems.
|
|
And, allow non-symbol keys as a keyword arugment

`umethod.bind_call(obj, ...)` is semantically equivalent to
`umethod.bind(obj).call(...)`. This idiom is used in some libraries to
call a method that is overridden. The added method does the same
without allocation of intermediate Method object. [Feature #15955]
```
class Foo
def add_1(x)
x + 1
end
end
class Bar < Foo
def add_1(x) # override
x + 2
end
end
obj = Bar.new
p obj.add_1(1) #=> 3
p Foo.instance_method(:add_1).bind(obj).call(1) #=> 2
p Foo.instance_method(:add_1).bind_call(obj, 1) #=> 2
```

To properly generate documents.

We can check the function pointer passed to rb_define_global_function
like we do so in rb_define_method. It turns out that almost anybody
is misunderstanding the API.

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.

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.
|
|
When we use `define_method` and `define_singleton_method`,
if we supply block parameters to a block then a generated
method has corresponding parameters.
However, the doc doesn't mention it, so this info has been added.
|
|
|
|
Now Proc#to_s returns
"#<Proc:0x00000237a0f5f170@t.rb:1>".
However, it is convenient to select a file name by (double-)clicking
on some terminals by separating ' ' instead of '@' like
"#<Proc:0x00000237a0f5f170 t.rb:1>"
[Feature #16101]

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.

Method#inspect shows with source location.

This commit adds compaction support for:
* Fibers
* Continuations
* Autoload Constants
|
|
This commit adds compaction support to method and proc objects. It just
unpins references and implements the "compact" callback and updates
references.
|
|
It refers to `Method#receiver` in the doc, but
there's no class reference in current doc.
Some tools automatically make it a link so it's useful.
Closes: https://github.com/ruby/ruby/pull/2156
|
|
This change adds an explicit reference to `TracePoint` in the
documentation for `binding`. Currently it only refers to the now
deprecated `Kernel#set_trace_func`. This reference is left alone for
continuity in the documentation.
