Hi everyone,

Rails 3.2.9 has been released without new changes since 3.2.9.rc3.

IMPORTANT!

A DoS attack was recently found in Ruby that uses specially-crafted input to dramatically reduce the performance of hashes, thus using up lots of CPU time. Rails applications may be vulnerable to an attacker sending a specially-crafted HTTP request to exploit this.

A good way to limit the effectiveness of such attacks is to configure your frontend servers to limit the size of the HTTP request line, headers and body. Nginx does this by default. Apache can be configured to do this by setting the LimitRequestBody directive.

In addition, all Ruby 1.9 users are recommended to upgrade to ruby-1.9.3 patchlevel 327 to get this security fix.

CHANGES since 3.2.8

Action Mailer

Do not render views when mail() isn’t called. Fix #7761 Yves Senn

Action Pack

Lock sprockets to 2.2.x REASON: We had some pending fixes in sprockets and sass-rails to make possible to use sprockets version > 2.2. We will do a more conservative sprockets upgrade for this release. In a next release we can relax the dependency again. See #8099 for more information. Guillermo Iguaran

Clear url helpers when reloading routes. Santiago Pastorino

Revert the shorthand routes scoped with :module option fix This added a regression since it is changing the URL mapping. This makes the stable release backward compatible. Rafael Mendonça França

Revert the assert_template fix to not pass with ever string that matches the template name. This added a regression since people were relying on this buggy behavior. This will introduce back #3849 but this stable release will be backward compatible. Fixes #8068. Rafael Mendonça França

Revert the rename of internal variable on ActionController::TemplateAssertions to prevent naming collisions. This added a regression related with shoulda-matchers, since it is expecting the instance variable @layouts. This will introduce back #7459 but this stable release will be backward compatible. Fixes #8068. Rafael Mendonça França

Accept :remote as symbolic option for link_to helper. Riley Lynch

Warn when the :locals option is passed to assert_template outside of a view test case Fix #3415 Yves Senn

Rename internal variables on ActionController::TemplateAssertions to prevent naming collisions. @partials, @templates and @layouts are now prefixed with an underscore. Fix #7459 Yves Senn

resource and resources don’t modify the passed options hash Fix #7777 Yves Senn

Precompiled assets include aliases from foo.js to foo/index.js and vice versa. # Precompiles phone-<digest>.css and aliases phone/index.css to phone.css. config.assets.precompile = [ 'phone.css' ] # Precompiles phone/index-<digest>.css and aliases phone.css to phone/index.css. config.assets.precompile = [ 'phone/index.css' ] # Both of these work with either precompile thanks to their aliases. <%= stylesheet_link_tag 'phone', media: 'all' %> <%= stylesheet_link_tag 'phone/index', media: 'all' %> Jeremy Kemper

assert_template is no more passing with what ever string that matches with the template name. Before when we have a template /layout/hello.html.erb , assert_template was passing with any string that matches. This behavior allowed false positive like: assert_template "layout" assert_template "out/hello" Now it only passes with: assert_template "layout/hello" assert_template "hello" Fixes #3849. Hugolnx

Handle ActionDispatch::Http::UploadedFile like Rack::Test::UploadedFile , don’t call to_param on it. Since Rack::Test::UploadedFile isn’t API compatible this is needed to test file uploads that rely on tempfile being available. Tim Vandecasteele

Fixed a bug with shorthand routes scoped with the :module option not adding the module to the controller as described in issue #6497. This should now work properly: scope :module => "engine" do get "api/version" # routes to engine/api#version end Luiz Felipe Garcia Pereira

Respect config.digest = false for asset_path Previously, the asset_path internals only respected the :digest option, but ignored the global config setting. This meant that config.digest = false could not be used in conjunction with config.compile = false this corrects the behavior. Peter Wagenet

Fix #7646, the log now displays the correct status code when an exception is raised. Yves Senn

Fix handling of date selects when using both disabled and discard options. Fixes #7431. Vasiliy Ermolovich

Fix select_tag when option_tags is nil. Fixes #7404. Sandeep Ravichandran

javascript_include_tag :all will now not include application.js if the file does not exists. Prem Sichanugrist

Support cookie jar options (e.g., domain :all) for all session stores. Fixes GH#3047, GH#2483. Ravil Bayramgalin

Performance Improvement to send_file: Avoid having to pass an open file handle as the response body. Rack::Sendfile will usually intercept the response and just uses the path directly, so no reason to open the file. This performance improvement also resolves an issue with jRuby encodings, and is the reason for the backport, see issue #6844. Jeremy Kemper & Erich Menge

Active Model

Due to a change in builder, nil values and empty strings now generates closed tags, so instead of this: <pseudonyms nil=\"true\"></pseudonyms> It generates this: <pseudonyms nil=\"true\"/> Carlos Antonio da Silva

Fix issue with collection associations calling first(n)/last(n) and attempting to set the inverse association when :inverse_of was used. Fixes #8087. Carlos Antonio da Silva

Fix ActiveRecord#update_column return value. Aliaxandr

Decode URI encoded attributes on database connection URLs. Shawn Veader

PostgreSQL adapter correctly fetches default values when using multiple schemas and domains in a db. Fixes #7914 Arturo Pie

Fix deprecation notice when loading a collection association that selects columns from other tables, if a new record was previously built using that association. Ernie Miller

The postgres adapter now supports tables with capital letters. Fix #5920 Yves Senn

CollectionAssociation#count returns 0 without querying if the parent record is not persisted. Before: person.pets.count # SELECT COUNT(*) FROM "pets" WHERE "pets"."person_id" IS NULL # => 0 After: person.pets.count # fires without sql query # => 0 Francesco Rodriguez

Fix reset_counters crashing on has_many :through associations. Fix #7822. lulalala

ConnectionPool recognizes checkout_timeout spec key as taking precedence over legacy wait_timeout spec key, can be used to avoid conflict with mysql2 use of wait_timeout. Closes #7684. jrochkind

Rename field_changed? to _field_changed? so that users can create a field named field Akira Matsuda, backported by Steve Klabnik

Fix creation of through association models when using collection=[] on a has_many :through association from an unsaved model. Fix #7661. Ernie Miller

Backport test coverage to ensure that PostgreSQL auto-reconnect functionality remains healthy. Steve Jorgensen

Use config[‘encoding’] instead of config[‘charset’] when executing databases.rake in the mysql/mysql2. A correct option for a database.yml is ‘encoding’. kennyj

Use inversed parent for first and last child of has_many association. Ravil Bayramgalin

Fix Column.microseconds and Column.fast_string_to_date to avoid converting timestamp seconds to a float, since it occasionally results in inaccuracies with microsecond-precision times. Fixes #7352. Ari Pollak

Fix increment! , decrement! , toggle! that was skipping callbacks. Fixes #7306. Rafael Mendonça França
