Subject: Re: [PATCH] Update respond_to? calls for second argument.
Date: Sun, 21 May 2017 04:54:35 +0000 [thread overview]
Message-ID: <20170521045435.GA17029@untitled> (raw)
Actually, there's also a rb_obj_respond_to API in Ruby 1.9+
which could be used. It's declared in ruby/intern.h which is a
grey area as far as continued API support goes, and it's not
documented in doc/extension.rdoc, either.
However, there is a rubyspec CAPI test for it; and I'm not sure
the two-arg form of respond_to? is actually used by real Rack
Sidenote: rb_funcall* functions are always a bit slower since
they need to go through method lookup before dispatch, and can't
benefit from inline method caching, only global method caching.
