From 8033d3370c56d8d69673c000182922228504706c Mon Sep 17 00:00:00 2001 From: Dmitriy Kiriyenko Date: Tue, 26 Nov 2013 17:03:25 +0200 Subject: [PATCH] Fix segmentation fault in Ruby 2.0.0-p353. In Ruby 2.0.0-p353 there was a [commit](https://github.com/ruby/ruby/commit/66915c507777c5e3a978fa73de25db763efd9206) that switched case matching from actual sending `===` method to magic lookup, that does not see it in `method_missing`. It's hard to predict how exactly and when exactly this bug will be solved so here I suggest a solution of defining it in Duration directly. In Ruby 2.0.0-p353 without the added fix added test crashes to segmentation fault. --- activesupport/lib/active_support/duration.rb | 8 ++++++++ activesupport/test/core_ext/duration_test.rb | 5 +++++ 2 files changed, 13 insertions(+) diff --git a/activesupport/lib/active_support/duration.rb b/activesupport/lib/active_support/duration.rb index 87b6407038..7df4857c25 100644 --- a/activesupport/lib/active_support/duration.rb +++ b/activesupport/lib/active_support/duration.rb @@ -99,6 +99,14 @@ module ActiveSupport private + # We define it as a workaround to Ruby 2.0.0-p353 bug. + # For more information, check rails/rails#13055. + # It should be dropped once a new Ruby patch-level + # release after 2.0.0-p353 happens. + def ===(other) #:nodoc: + value === other + end + def method_missing(method, *args, &block) #:nodoc: value.send(method, *args, &block) end diff --git a/activesupport/test/core_ext/duration_test.rb b/activesupport/test/core_ext/duration_test.rb index 47257debe4..8eae8c832c 100644 --- a/activesupport/test/core_ext/duration_test.rb +++ b/activesupport/test/core_ext/duration_test.rb @@ -158,6 +158,11 @@ class DurationTest < ActiveSupport::TestCase assert_equal '172800', 2.days.to_json end + def test_case_when + cased = case 1.day when 1.day then "ok" end + assert_equal cased, "ok" + end + protected def with_env_tz(new_tz = 'US/Eastern') old_tz, ENV['TZ'] = ENV['TZ'], new_tz
