Hi, I am working on upgrading our project from 2.7 to 3.x and found a breaking change in `instance_method` behavior.
Here is the code snippet
```
module A
def test(*args)
super
end
end
module B
def test(a)
puts a
end
end
B.prepend(A)
a = lambda do
puts 'lambda'
end
class C
include B
end
B.instance_method(:test).bind(C.new).call(1)
# Ruby 2.7: 1
# Ruby 3.0: 1
# Ruby 3.1: 1
B.module_exec do
define_method(:test, a)
end
B.instance_method(:test).bind(C.new).call
# Ruby 2.7: lambda
# Ruby 3.0: wrong number of arguments (given 0, expected 1) (ArgumentError)
# Ruby 3.1: wrong number of arguments (given 0, expected 1) (ArgumentError)
```
I don't know if this is a bug or a correct intention.

Issue #20716 has been updated by jeremyevans0 (Jeremy Evans).
This appears to be a method caching bug in `super`. If you remove the `.call(1)`, then it works correctly. `super_method` returns the correct method. The `define_method(:test, a)` call should result in the method cache being cleared or ignored, but it doesn't. However, it isn't specific to `define_method`, regular `def` results in the same behavior.

Yes, you are correct. This isn't specific to `define_method`. I modified the snippet a little bit
```
module A
def test(*args)
super
end
end
module B
def test(a)
puts a
end
end
B.prepend(A)
class C
include B
end
C.new.test(1)
# Ruby 2.7: 1
# Ruby 3.0: 1
# Ruby 3.1: 1
module B
def test
puts 'new test'
end
end
C.new.test
# Ruby 2.7: 'new test'
# Ruby 3.0: wrong number of arguments (given 0, expected 1) (ArgumentError)
# Ruby 3.1: wrong number of arguments (given 0, expected 1) (ArgumentError)

Issue #20716 has been updated by jeremyevans0 (Jeremy Evans).
This behavior isn't related to `instance_method`. It occurs in the following code:
```ruby
module A
def test(*args)
super
end
end
module B
def test(a)
puts a
end
end
class C; end
B.prepend(A)
C.include(B)
C.new.test 1
module B
def test
puts 'lambda'
end
end
C.new.test
```
It also happens when you replace `C.include(B)` with `C.prepend(B)`.
It does not happen when you replace `B.prepend(A); C.include(B)` with `A.include(B); C.include(A)`. It also does not happen if a class directly prepends a module, such as in this example:
```ruby
module A
def test(*args)
super
end
end
class B
def test(a)
puts a
end
end
B.prepend(A)
B.new.test 1
class B
def test
puts 'lambda'
end
end
B.new.test
```
It seems like the conditions are:
* Class includes or prepends module X that prepends module Y
* Both X and Y define method M
* Y's definition of M calls `super`
* X's definition of M is overridden after `super` method call is cached

Hi Evans,
Thank you for your confirmation.

There isn't an escalation process in place in Ruby, as it is an open source project managed by volunteers. In terms of helping to resolve the issue, first, we need to determine the cause of the bug. Bisecting changes between 2.7 and 3.0 would help here to confirm the actual commit that caused the issue (the commit I listed in an early comment is just a guess). I tried bisecting myself, but I think the current version of bison doesn't work with the parse.y of 2.7, so bisecting is more challenging than usual.
After the problem has been determined, then an appropriate fix needs to be determined. This is likely more challenging, and requires knowledge and/or study of how method caching works in Ruby.
If this isn't work you are comfortable doing yourself, and it's important enough that you are willing to pay to have it fixed, you could pay a developer to do so on your behalf, or you could offer a bounty for a developer to fix it for you. There are no guarantees of success, of course, but it likely increases the odds.
Considering this bug has been around for about 4 years, and this is the first time it has been reported, this doesn't seem like a major issue, and it should be fairly easy to work around by overriding the method before calling `super`. That said, I would still like to see it fixed, and likely will work on it more myself at some point. However, I don't have extensive knowledge of Ruby's method caching, and there are other bugs I'm working on fixing.

Backport changed from 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN to 3.1: REQUIRED, 3.2: REQUIRED, 3.3: REQUIRED
I was able to track down the cause and submitted a pull request to fix this: https://github.com/ruby/ruby/pull/11582
It appears to be introduced by commit:ad729a1d11c6c57efd2e92803b4e937db0f75252, which I wrote and which was a fix for #16736.

Bug #20716: Different instance_method behavior in Ruby 2.7 and Ruby 3.x
https://bugs.ruby-lang.org/issues/20716#change-109701
* Author: natton (Tien Truong)
* Status: Open

* Backport: 3.1: REQUIRED, 3.2: REQUIRED, 3.3: REQUIRED
----------------------------------------
Hi, I am working on upgrading our project from 2.7 to 3.x and found a breaking change in `instance_method` behavior.
Here is the code snippet
```
module A
def test(*args)
super
end
end
module B
def test(a)
puts a
end
end
B.prepend(A)
a = lambda do
puts 'lambda'
end
class C
include B
end
B.instance_method(:test).bind(C.new).call(1)
# Ruby 2.7: 1
# Ruby 3.0: 1
# Ruby 3.1: 1
B.module_exec do
define_method(:test, a)
end
B.instance_method(:test).bind(C.new).call
# Ruby 2.7: lambda
# Ruby 3.0: wrong number of arguments (given 0, expected 1) (ArgumentError)
# Ruby 3.1: wrong number of arguments (given 0, expected 1) (ArgumentError)
```
I don't know if this is a bug or a correct intention.

Ruby 3.2 was recently fixed, and it will be in the next Ruby 3.2 release. Ruby 3.1 is in security fix only mode, and this is not a security fix, so I do not think it will be patched.
