	Fix use-after-free in ep in Proc#dup for ifunc procs

	[Bug #20950]

	ifunc proc has the ep allocated in the cfunc_proc_t which is the data of
	the TypedData object. If an ifunc proc is duplicated, the ep points to
	the ep of the source object. If the source object is freed, then the ep
	of the duplicated object now points to a freed memory region. If we try
	to use the ep we could crash.

	For example, the following script crashes:

	    p = { a: 1 }.to_proc
	    100.times do
	      p = p.dup
	      GC.start
	      p.call
	    rescue ArgumentError
	    end

	This commit changes ifunc proc to also duplicate the ep when it is duplicated.

	[Bug #20853] Fix Proc#hash to not change after compaction

	The hash value of a Proc must remain constant after a compaction, otherwise
	it may not work as the key in a hash table.

Make Kernel#lambda raise when given non-literal block

2023-09-12T15:25:07+00:00

Previously, Kernel#lambda returned a non-lambda proc when given a
non-literal block and issued a warning under the `:deprecated` category.
With this change, Kernel#lambda will always return a lambda proc, if it
returns without raising.

Due to interactions with block passing optimizations, we previously had
two separate code paths for detecting whether Kernel#lambda got a
literal block. This change allows us to remove one path, the hack done
with rb_control_frame_t::block_code introduced in 85a337f for supporting
situations where Kernel#lambda returned a non-lambda proc.

Fix autosplat conditions to handle ruby2_keywords case

2023-07-10T17:06:23+00:00

Autosplat should not occur if there are two arguments but second
argument is an array containing a ruby2_keywords splat. Only
autosplat if a single argument to be yielded to the block, and there
is no splatted flagged keyword hash passed.

Fixes [Bug #19759]

Raise RuntimeError if Kernel#binding is called from a non-Ruby frame

2022-04-07T02:14:03+00:00

Check whether the current or previous frame is a Ruby frame in
call_trace_func and rb_tracearg_binding before attempting to
create a binding for the frame.

Revert "Raise RuntimeError if Kernel#binding is called from a non-Ruby frame"

2022-04-01T14:22:49+00:00

This reverts commit 343ea9967e4a6b279eed6bd8e81ad0bdc747f254.

This causes an assertion failure with -DRUBY_DEBUG=1 -DRGENGC_CHECK_MODE=2

Do not autosplat array in block call just because keywords accepted

2022-03-30T18:03:56+00:00

If the block only accepts a single positional argument plus keywords,
then do not autosplat.  Still autosplat if the block accepts more
than one positional argument in addition to keywords.

Autosplatting a single positional argument plus keywords made sense
in Ruby 2, since a final positional hash could be used as keywords,
but it does not make sense in Ruby 3.

Make Proc#parameters support lambda keyword for returning parameters as if lambda

This makes it easier to use Proc#parameters to build wrappers.
