[ruby-core:35556] [Ruby 1.9 - Feature #4528][Open] [PATCH] ext/io/nonblock: avoid unnecessary fcntl F_SETFL calls

From: Eric Wong <normalperson@...>
Date: 2011-03-25 18:38:17 UTC
List: ruby-core #35556
Issue #4528 has been reported by Eric Wong.

----------------------------------------
Feature #4528: [PATCH] ext/io/nonblock: avoid unnecessary fcntl F_SETFL calls
http://redmine.ruby-lang.org/issues/4528

Author: Eric Wong
Status: Open
Priority: Low
Assignee: 
Category: ext
Target version: 1.9.x


Avoid F_SETFL if we're not changing the O_NONBLOCK bit.  F_SETFL
is an expensive operation since it needs to affect all processes
with the same file object.

rb_io_set_nonblock() implements similar logic to avoid F_SETFL
in io.c
