From 64c88fb5d2caf3c34742a07394ac68b8377c4936 Mon Sep 17 00:00:00 2001 From: Godfrey Chan Date: Wed, 11 Sep 2013 18:36:23 -0700 Subject: Moved all JSON core extensions into core_ext/object/json TL;DR The primary driver is to remove autoload surprise. This is related to #12106. (The root cause for that ticket is that json/add defines Regexp#to_json among others, but here I'll reproduce the problem without json/add.) Before: >> require 'active_support/core_ext/to_json' => true >> //.as_json NoMethodError: undefined method `as_json' for //:Regexp from (irb):3 from /Users/godfrey/.rvm/rubies/ruby-2.0.0-p195/bin/irb:16:in `
' >> //.to_json => "\"(?-mix:)\"" >> //.as_json => "(?-mix:)" After: >> require 'active_support/core_ext/to_json' => true >> //.as_json => "(?-mix:)" This is because ActiveSupport::JSON is autoloaded the first time Object#to_json is called, which causes additional core extentions (previously defined in active_support/json/encoding.rb) to be loaded. When someone require 'active_support/core_ext', the expectation is that it would add certain methods to the core classes NOW. The previous behaviour causes additional methods to be loaded the first time you call `to_json`, which could cause nasty surprises and other unplesant side-effects. This change moves all core extensions in to core_ext/json. AS::JSON is still autoloaded on first #to_json call, but since it nolonger include the core extensions, it should address the aforementioned bug. *Requiring core_ext/object/to_json now causes a deprecation warnning* --- activesupport/test/core_ext/object/json_test.rb | 9 +++++++++ 1 file changed, 9 insertions(+) create mode 100644 activesupport/test/core_ext/object/json_test.rb (limited to 'activesupport/test/core_ext/object/json_test.rb') diff --git a/activesupport/test/core_ext/object/json_test.rb b/activesupport/test/core_ext/object/json_test.rb new file mode 100644 index 0000000000..d3d31530df --- /dev/null +++ b/activesupport/test/core_ext/object/json_test.rb @@ -0,0 +1,9 @@ +require 'abstract_unit' + +class JsonTest < ActiveSupport::TestCase + # See activesupport/test/json/encoding_test.rb for JSON encoding tests + + def test_deprecated_require_to_json_rb + assert_deprecated { require 'active_support/core_ext/object/to_json' } + end +end -- cgit v1.2.3
