From 6aa115e41f43b179d4c74526aa250d01e823d48d Mon Sep 17 00:00:00 2001 From: claudiob Date: Fri, 17 Oct 2014 11:38:00 -0700 Subject: Replace (slower) block.call with (faster) yield MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Performance optimization: `yield` with an implicit `block` is faster than `block.call`. See http://youtu.be/fGFM_UrSp70?t=10m35s and the following benchmark: ```ruby require 'benchmark/ips' def fast yield end def slow(&block) block.call end Benchmark.ips do |x| x.report('fast') { fast{} } x.report('slow') { slow{} } end # => fast 154095 i/100ms # => slow 71454 i/100ms # => # => fast 7511067.8 (±5.0%) i/s - 37445085 in 4.999660s # => slow 1227576.9 (±6.8%) i/s - 6145044 in 5.028356s ``` --- activesupport/lib/active_support/testing/time_helpers.rb | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'activesupport/lib/active_support/testing/time_helpers.rb') diff --git a/activesupport/lib/active_support/testing/time_helpers.rb b/activesupport/lib/active_support/testing/time_helpers.rb index 1112c6e0b1..8c63815660 100644 --- a/activesupport/lib/active_support/testing/time_helpers.rb +++ b/activesupport/lib/active_support/testing/time_helpers.rb @@ -90,7 +90,7 @@ module ActiveSupport # Time.current # => Wed, 24 Nov 2004 01:04:44 EST -05:00 # end # Time.current # => Sat, 09 Nov 2013 15:34:49 EST -05:00 - def travel_to(date_or_time, &block) + def travel_to(date_or_time) if date_or_time.is_a?(Date) && !date_or_time.is_a?(DateTime) now = date_or_time.midnight.to_time else @@ -102,7 +102,7 @@ module ActiveSupport if block_given? begin - block.call + yield ensure travel_back end -- cgit v1.2.3
