[ANN] Rails 3.2.13.rc1 has been released!

hatless · February 27, 2013, 9:29pm

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 S.
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 S.
Add i18n scope to distance_of_time_in_words. [Backport #7997]
Steve K.

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 H. & 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 K.
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 B.
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 S.
Fix ActiveRecord::Relation#pluck when columns or tables are
reserved words.
Backport #7536.
Fix #8968.

Ian Lesperance + Yves Senn + Kaspar S.
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 Mendona Frana
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 Mendona Frana
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 K.
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 M.
#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 S.
