Description
Hello,
It seems like I found a behavior change on the way method missing is working on Ruby 2.7.2 in comparison with 2.6.6.
method_missing
can't intercept call to a method called system
.
The following code help reproducing the behavior
class Klass
def method_missing(meth, *args, &blk)
if %i[system foo].include?(meth)
puts 'behavior not reproductible'
else
super
end
end
# Work on 2.6.6
def call_system_from_self
self.system
end
# Doesn't work on both
def call_system_from_implicit_self
system
end
# Work on both
def call_foo_from_self
self.foo
end
# Work on both
def call_foo_from_implicit_self
foo
end
# Doesn't work on both
def call_system_with_send_from_self
self.send(:system)
end
# Work on both
def call_foo_with_send_from_self
self.send(:foo)
end
# Work on both
def call_system_with_public_send
self.public_send(:system)
end
# Work on both
def call_foo_with_public_send
self.public_send(:foo)
end
end
Is it an expected behavior change in 2.7.2?
