Rails 3.2.13.rc1 has been released!

Hey everyone! I am pumped to announce that Rails 3.2.13.rc1 has been released! If no regressions are found I will release 3.2.13 final in two weeks, on March 13, 2013. If you find one, please [Open an Issue on GitHub](Sign in to GitHub · GitHub) so that I can fix it before the final release.

This is a bugfix release, with 287 commits. There is one big thing that is technically a fix but is sort of a feature: Ruby 2.0 support. Big thanks to Prem Sichanugrist for putting that together! Please give your applications a try on Ruby 2.0 and let me know how that goes.

## CHANGES since 3.2.12

*Action Mailer*

No changes.

*Action Pack*

* Determine the controller#action from only the matched path when using the     shorthand syntax. Previously the complete path was used, which led     to problems with nesting (scopes and namespaces).     Fixes #7554.     Backport #9361.

    Example:

        # this will route to questions#new         scope ':locale' do           get 'questions/new'         end

    *Yves Senn*

* Fix `assert_template` with `render :stream => true`.     Fix #1743.     Backport #5288.

    *Sergey Nartimov*

* Eagerly populate the http method loookup cache so local project inflections do     not interfere with use of underscore method ( and we don't need locks )

    *Aditya Sanghi*

* `BestStandardsSupport` no longer duplicates `X-UA-Compatible` values on     each request to prevent header size from blowing up.

    *Edward Anderson*

* Fixed JSON params parsing regression for non-object JSON content.

    *Dylan Smith*

* Prevent unnecessary asset compilation when using `javascript_include_tag` on     files with non-standard extensions.

    *Noah Silas*

* Fixes issue where duplicate assets can be required with sprockets.

    *Jeremy Jackson*

* Bump `rack` dependency to 1.4.3, eliminate `Rack::File` headers deprecation warning.

    *Sam Ruby + Carlos Antonio da Silva*

* Do not append second slash to `root_url` when using `trailing_slash: true`

    Fix #8700.     Backport #8701.

    Example:         # before         root_url # => http://test.host//

        # after         root_url # => http://test.host/

    *Yves Senn*

* Fix a bug in `content_tag_for` that prevents it for work without a block.

    *Jasl*

* Clear url helper methods when routes are reloaded by removing the methods     explicitly rather than just clearing the module because it didn't work     properly and could be the source of a memory leak.

    *Andrew White*

* Fix a bug in `ActionDispatch::Request#raw_post` that caused `env['rack.input']`     to be read but not rewound.

    *Matt Venables*

* More descriptive error messages when calling `render :partial` with     an invalid `:layout` argument.

    Fixes #8376.

        render :partial => 'partial', :layout => true         # results in ActionView::MissingTemplate: Missing partial /true

    *Yves Senn*

* Accept symbols as `#send_data` :disposition value. [Backport #8329] *Elia Schito*

* Add i18n scope to `distance_of_time_in_words`. [Backport #7997] *Steve Klabnik*

* Fix side effect of `url_for` changing the `:controller` string option. [Backport #6003]     Before:

        controller = '/projects'         url_for :controller => controller, :action => 'status'

        puts controller #=> 'projects'

    After

        puts controller #=> '/projects'

    *Nikita Beloglazov + Andrew White*

* Introduce `ActionView::Template::Handlers::ERB.escape_whitelist`. This is a list     of mime types where template text is not html escaped by default. It prevents `Jack & Joe`     from rendering as `Jack & Joe` for the whitelisted mime types. The default whitelist     contains text/plain. Fix #7976 [Backport #8235]

    *Joost Baaij*

* `BestStandardsSupport` middleware now appends it's `X-UA-Compatible` value to app's     returned value if any. Fix #8086 [Backport #8093]

    *Nikita Afanasenko*

* prevent double slashes in engine urls when `Rails.application.default_url_options[:trailing_slash] = true` is set     Fix #7842

    *Yves Senn*

* Fix input name when `:multiple => true` and `:index` are set.

    Before:

        check_box("post", "comment_ids", { :multiple => true, :index => "foo" }, 1)         #=> <input name=\"post[foo][comment_ids]\" type=\"hidden\" value=\"0\" /><input id=\"post_foo_comment_ids_1\" name=\"post[foo][comment_ids]\" type=\"checkbox\" value=\"1\" />

    After:

        check_box("post", "comment_ids", { :multiple => true, :index => "foo" }, 1)         #=> <input name=\"post[foo][comment_ids]\" type=\"hidden\" value=\"0\" /><input id=\"post_foo_comment_ids_1\" name=\"post[foo][comment_ids]\" type=\"checkbox\" value=\"1\" />

    Fix #8108

    *Daniel Fox, Grant Hutchins & Trace Wax*

*Active Model*

* Specify type of singular association during serialization *Steve Klabnik*

*Active Record*

* Reverted 921a296a3390192a71abeec6d9a035cc6d1865c8, 'Quote numeric values     compared to string columns.' This caused several regressions.

    *Steve Klabnik*

* Fix overriding of attributes by default_scope on `ActiveRecord::Base#dup`.

    *Hiroshige UMINO*

* Fix issue with overriding Active Record reader methods with a composed object     and using that attribute as the scope of a `uniqueness_of` validation.     Backport #7072.

    *Peter Brown*

* Sqlite now preserves custom primary keys when copying or altering tables.     Fixes #9367.     Backport #2312.

    *Sean Scally + Yves Senn*

* Preloading `has_many :through` associations with conditions won't     cache the `:through` association. This will prevent invalid     subsets to be cached.     Fixes #8423.     Backport #9252.

    Example:

        class User           has_many :posts           has_many :recent_comments, -> { where('created_at > ?', 1.week.ago) }, :through => :posts         end

        a_user = User.includes(:recent_comments).first

        # this is preloaded         a_user.recent_comments

        # fetching the recent_comments through the posts association won't preload it.         a_user.posts

    *Yves Senn*

* Fix handling of dirty time zone aware attributes

    Previously, when `time_zone_aware_attributes` were enabled, after     changing a datetime or timestamp attribute and then changing it back     to the original value, `changed_attributes` still tracked the     attribute as changed. This caused `[attribute]_changed?` and     `changed?` methods to return true incorrectly.

    Example:

        in_time_zone 'Paris' do           order = Order.new           original_time = Time.local(2012, 10, 10)           order.shipped_at = original_time           order.save           order.changed? # => false

          # changing value           order.shipped_at = Time.local(2013, 1, 1)           order.changed? # => true

          # reverting to original value           order.shipped_at = original_time           order.changed? # => false, used to return true         end

    Backport of #9073     Fixes #8898

    *Lilibeth De La Cruz*

* Fix counter cache columns not updated when replacing `has_many :through`     associations.     Backport #8400.     Fix #7630.

    *Matthew Robertson*

* Don't update `column_defaults` when calling destructive methods on column with default value.     Backport c517602.     Fix #6115.

    *Piotr Sarnacki + Aleksey Magusev + Alan Daud*

* When `#count` is used in conjunction with `#uniq` we perform `count(:distinct => true)`.     Fix #6865.

    Example:

      relation.uniq.count # => SELECT COUNT(DISTINCT *)

    *Yves Senn + Kaspar Schiess*

* Fix `ActiveRecord::Relation#pluck` when columns or tables are reserved words.     Backport #7536.     Fix #8968.

    *Ian Lesperance + Yves Senn + Kaspar Schiess*

* Don't run explain on slow queries for database adapters that don't support it.     Backport #6197.

    *Blake Smith*

* Revert round usec when comparing timestamp attributes in the dirty tracking.     Fixes #8460.

    *Andrew White*

* Revert creation of through association models when using `collection=`     on a `has_many :through` association from an unsaved model.     Fix #7661, #8269.

    *Ernie Miller*

* Fix undefined method `to_i` when calling `new` on a scope that uses an     Array; Fix FloatDomainError when setting integer column to NaN.     Fixes #8718, #8734, #8757.

    *Jason Stirk + Tristan Harward*

* Serialized attributes can be serialized in integer columns.     Fix #8575.

    *Rafael Mendonça França*

* Keep index names when using `alter_table` with sqlite3.     Fix #3489.     Backport #8522.

    *Yves Senn*

* Recognize migrations placed in directories containing numbers and 'rb'.     Fix #8492.     Backport of #8500.

    *Yves Senn*

* Add `ActiveRecord::Base.cache_timestamp_format` class attribute to control     the format of the timestamp value in the cache key.     This allows users to improve the precision of the cache key.     Fixes #8195.

    *Rafael Mendonça França*

* Add `:nsec` date format. This can be used to improve the precision of cache key.     Please note that this format only works with Ruby 1.9, Ruby 1.8 will ignore it completely.

    *Jamie Gaskins*

* Unscope `update_column(s)` query to ignore default scope.

    When applying `default_scope` to a class with a where clause, using     `update_column(s)` could generate a query that would not properly update     the record due to the where clause from the `default_scope` being applied     to the update query.

        class User < ActiveRecord::Base           default_scope where(active: true)         end

        user = User.first         user.active = false         user.save!

        user.update_column(:active, true) # => false

    In this situation we want to skip the default_scope clause and just     update the record based on the primary key. With this change:

        user.update_column(:active, true) # => true

    Backport of #8436 fix.

    *Carlos Antonio da Silva*

* Fix performance problem with primary_key method in PostgreSQL adapter when having many schemas.     Uses pg_constraint table instead of pg_depend table which has many records in general.     Fix #8414

    *kennyj*

* Do not instantiate intermediate Active Record objects when eager loading.     These records caused `after_find` to run more than expected.     Fix #3313     Backport of #8403

    *Yves Senn*

* Fix `pluck` to work with joins. Backport of #4942.

    *Carlos Antonio da Silva*

* Fix a problem with `translate_exception` method in a non English environment.     Backport of #6397.

    *kennyj*

* Fix dirty attribute checks for TimeZoneConversion with nil and blank     datetime attributes. Setting a nil datetime to a blank string should not     result in a change being flagged.     Fixes #8310.     Backport of #8311.

    *Alisdair McDiarmid*

* Prevent mass assignment to the type column of polymorphic associations when using `build`.     Fixes #8265.     Backport of #8291.

    *Yves Senn*

* When running migrations on Postgresql, the `:limit` option for `binary` and `text` columns is     silently dropped.     Previously, these migrations caused sql exceptions, because Postgresql doesn't support limits     on these types.

    *Victor Costan*

* `#pluck` can be used on a relation with `select` clause.     Fixes #7551.     Backport of #8176.

    Example:

        Topic.select([:approved, :id]).order(:id).pluck(:id)

    *Yves Senn*

* Use `nil?` instead of `blank?` to check whether dynamic finder with a bang     should raise RecordNotFound.     Fixes #7238.

    *Nikita Afanasenko*

* Fix deleting from a HABTM join table upon destroying an object of a model     with optimistic locking enabled.     Fixes #5332.

    *Nick Rogers*

* Use query cache/uncache when using ENV["DATABASE_URL"].     Fixes #6951.     Backport of #8074.

    *kennyj*

* Do not create useless database transaction when building `has_one` association.

    Example:

        User.has_one :profile         User.new.build_profile

    Backport of #8154.

    *Bogdan Gusiev*

* `AR::Base#attributes_before_type_cast` now returns unserialized values for serialized attributes.

    *Nikita Afanasenko*

* Fix issue that raises `NameError` when overriding the `accepts_nested_attributes` in child classes.

    Before:

        class Shared::Person < ActiveRecord::Base           has_one :address

          accepts_nested_attributes :address, :reject_if => :all_blank         end

        class Person < Shared::Person           accepts_nested_attributes :address         end

        Person         #=> NameError: method `address_attributes=' not defined in Person

    After:

        Person         #=> Person(id: integer, ...)

    Fixes #8131.

    *Gabriel Sobrinho, Ricardo Henrique*

*Active Resource*

No changes.

*Active Support*

* Fix DateTime comparison with DateTime::Infinity object.

    *Dan Kubb*

* Remove surrogate unicode character encoding from ActiveSupport::JSON.encode     The encoding scheme was broken for unicode characters outside the basic     multilingual plane; since json is assumed to be UTF-8, and we already force the     encoding to UTF-8 simply pass through the un-encoded characters.

    *Brett Carter*

* Fix mocha v0.13.0 compatibility. *James Mead*

* `#as_json` isolates options when encoding a hash. [Backport #8185]     Fix #8182

    *Yves Senn*

* Handle the possible Permission Denied errors atomic.rb might trigger due to     its chown and chmod calls. [Backport #8027]

    *Daniele Sluijters*

*Railties*

No changes.
