From 099eb2b3fd9526e06c30b9878780f31091e011aa Mon Sep 17 00:00:00 2001 From: David Lee Date: Sun, 8 May 2011 02:21:06 -0700 Subject: indifferent access should recurse Hash subclasses This commit makes Hash subclasses convert to HWIA by default for nested objects of subclasses of Hash, but allows certain subclasses to prevent nested conversion by introducing Hash#nested_under_indifferent_access that subclasses can overwrite. ActiveSupport::OrderedHash is one such subclass that overwrites +nested_under_indifferent_access+, since implicitly converting it to HWIA would remove the ordering of keys and values in Ruby 1.8. This change is necessary because commit ce9456e broke nested indifferent access conversion for all subclasses of Hash. --- activesupport/test/core_ext/hash_ext_test.rb | 15 ++++++++++++--- 1 file changed, 12 insertions(+), 3 deletions(-) (limited to 'activesupport/test/core_ext/hash_ext_test.rb') diff --git a/activesupport/test/core_ext/hash_ext_test.rb b/activesupport/test/core_ext/hash_ext_test.rb index 3ef080e1cb..4557a10688 100644 --- a/activesupport/test/core_ext/hash_ext_test.rb +++ b/activesupport/test/core_ext/hash_ext_test.rb @@ -16,6 +16,12 @@ class HashExtTest < Test::Unit::TestCase class SubclassingHash < Hash end + class NonIndifferentHash < Hash + def nested_under_indifferent_access + self + end + end + def setup @strings = { 'a' => 1, 'b' => 2 } @symbols = { :a => 1, :b => 2 } @@ -109,9 +115,12 @@ class HashExtTest < Test::Unit::TestCase assert_equal @strings, @mixed.with_indifferent_access.dup.stringify_keys! end - def test_hash_subclass - flash = { "foo" => SubclassingHash.new.tap { |h| h["bar"] = "baz" } }.with_indifferent_access - assert_kind_of SubclassingHash, flash["foo"] + def test_nested_under_indifferent_access + foo = { "foo" => SubclassingHash.new.tap { |h| h["bar"] = "baz" } }.with_indifferent_access + assert_kind_of ActiveSupport::HashWithIndifferentAccess, foo["foo"] + + foo = { "foo" => NonIndifferentHash.new.tap { |h| h["bar"] = "baz" } }.with_indifferent_access + assert_kind_of NonIndifferentHash, foo["foo"] end def test_indifferent_assorted -- cgit v1.2.3
