Bug #14335: block.call should respect redefinition of Proc#call

• Status: Closed
• Assignee: -
• Target version: 2.6
• ruby -v: ruby 2.6.0dev (2018-01-08 master 61663) [x86_64-linux]
• Backport: 2.3: DONTNEED, 2.4: DONTNEED, 2.5: DONTNEED

[ktsj (Kazuki Tsujimoto)]

r61659の変更によって、
ブロック引数に対してcallメソッドを呼び出したときに
Proc#callの再定義が無視されるようになっています。

$ cat t.rb
Proc.prepend Module.new {
  def call
    p :call
    super
  end
}

def m(&blk)
  yield
  blk.call
end

m {}

$ ruby -v t.rb
ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-linux]
:call

$ ./ruby -v t.rb
ruby 2.6.0dev (2018-01-08 master 61663) [x86_64-linux]

vm.c: respect redefinition of Proc#call

• vm.c (vm_redefinition_check_method_type): hoist out method
  definition type to check redefinition.

• vm.c (rb_vm_check_redefinition_opt_method): should check
  optimized method too.

• vm.c (vm_init_redefined_flag): check Proc#call.

• vm_insnhelper.c (vm_call_opt_block_call): search proper method
  if redefined. [Bug #14335]
