Fix UnboundMethod#== for methods from included/extended modules [Backport #21873]

2026-03-07T05:41:17+00:00

Method#unbind clones the method entry, preserving its defined_class.
For methods mixed in via include/extend, defined_class is an ICLASS,
causing UnboundMethod#== to return false when comparing against the
same method obtained via Module#instance_method.

Resolve ICLASS defined_class in method_eq.

	[PATCH] Fix refinement modification of method visibility in superclass

	Previously, this didn't work correctly, resulting in a
	SystemStackError. This fixes the issue by finding the related
	superclass method entry, and updating the orig_me in the
	refinement method to point to the superclass method.

	Fixes [Bug #21446]

Fix allocationless anonymous splat keyword argument check

2025-12-12T16:56:50+00:00

Previously, if an argument splat and keywords are provided by
the caller, it did not check whether the method/proc accepted
keywords before avoiding the allocation. This is incorrect,
because if the method/proc does not accept keywords, the
keywords passed by the caller are added as a positional
argument, so there must be an allocation to avoid mutating
the positional splat argument.

Add a check that if the caller passes keywords, the
method/proc must accept keywords in order to optimize.
If the caller passes a keyword splat, either the
method/proc must accept keywords, or the keyword splat must
be empty in order to optimize.

If keywords are explicitly disallowed via `**nil`, the
optimization should be skipped, because the array is mutated
before the ArgumentError exception is raised.

In addition to a test for the correct behavior, add an
allocation test for a method that accepts an anonymous splat
without keywords.
