[ANN] 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 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 primarykey method in PostgreSQL adapter when having many schemas. Uses pgconstraint 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.

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]
