[ANN] Rails 3.2.9 has been released!

Hi everyone,

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


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

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 Mendona Frana

  • 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
    This will introduce back #3849 but this stable release will be
    backward compatible.
    Fixes #8068.

    Rafael Mendona Frana

  • 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
    This will introduce back #7459 but this stable release will be
    backward compatible.
    Fixes #8068.

    Rafael Mendona Frana

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

  • 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
    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 

<%= stylesheet_link_tag ‘phone’, media: ‘all’ %>
<%= stylesheet_link_tag ‘phone/index’, media: ‘all’ %>

*Jeremy K.*
  • assert_template is no more passing with what ever string that
    with the template name.

    Before when we have a template /layout/hello.html.erb,
    was passing with any string that matches. This behavior allowed
    positive like:

    assert_template "layout"
    assert_template "out/hello"

    Now it only passes with:

    assert_template "layout/hello"
    assert_template "hello"

    Fixes #3849.


  • 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
    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

    Luiz Felipe G. 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
    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
    Fixes GH#3047, GH#2483.

    Ravil B.

  • 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 K. & Erich Menge

Active Model

  • Due to a change in builder, nil values and empty strings now
    closed tags, so instead of this:

    <pseudonyms nil=\"true\"></pseudonyms>

    It generates this:

    <pseudonyms nil=\"true\"/>

    Carlos Antonio da Silva

    and attempting
    to set the inverse association when :inverse_of was used. Fixes

    you update the primary key column.

    Henrik N.

  • Decode URI encoded attributes on database connection URLs.

    Shawn Veader

  • Fix AR#dup to nullify the validation errors in the dup’ed object.

    and the dup’ed object shared the same errors.

    • Christian S.*
  • Synchronize around deleting from the reserved connections hash.
    Fixes #7955

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

    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.


    # SELECT COUNT(*) FROM "pets" WHERE "pets"."person_id" IS NULL
    # => 0


    # fires without sql query
    # => 0

    Francesco Rodriguez

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


  • ConnectionPool recognizes checkout_timeout spec key as taking
    precedence over legacy wait_timeout spec key, can be used to avoid

    Fix problem that explains unexplainable sql. Closes #7544 #6458.


  • Backport test coverage to ensure that PostgreSQL auto-reconnect
    remains healthy.

    Steve J.

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


  • Fix ConnectionAdapters::Column.type_cast_code integer conversion,
