* Allow `config.action_dispatch.trusted_proxies` to accept an IPAddr object.
Example:
# config/environments/production.rb
config.action_dispatch.trusted_proxies = IPAddr.new('4.8.15.0/16')
*Sam Aarons*
* Avoid duplicating routes for HEAD requests.
Instead of duplicating the routes, we will first match the HEAD request to
HEAD routes. If no match is found, we will then map the HEAD request to
GET routes.
*Guo Xiang Tan*, *Andrew White*
* Requests that hit `ActionDispatch::Static` can now take advantage
of gzipped assets on disk. By default a gzip asset will be served if
the client supports gzip and a compressed file is on disk.
*Richard Schneeman*
* `ActionController::Parameters` will stop inheriting from `Hash` and
`HashWithIndifferentAccess` in the next major release. If you use any method
that is not available on `ActionController::Parameters` you should consider
calling `#to_h` to convert it to a `Hash` first before calling that method.
*Prem Sichanugrist*
* `ActionController::Parameters#to_h` now returns a `Hash` with unpermitted
keys removed. This change is to reflect on a security concern where some
method performed on an `ActionController::Parameters` may yield a `Hash`
object which does not maintain `permitted?` status. If you would like to
get a `Hash` with all the keys intact, duplicate and mark it as permitted
before calling `#to_h`.
params = ActionController::Parameters.new({
name: 'Senjougahara Hitagi',
oddity: 'Heavy stone crab'
})
params.to_h
# => {}
unsafe_params = params.dup.permit!
unsafe_params.to_h
# => {"name"=>"Senjougahara Hitagi", "oddity"=>"Heavy stone crab"}
safe_params = params.permit(:name)
safe_params.to_h
# => {"name"=>"Senjougahara Hitagi"}
This change is consider a stopgap as we cannot change the code to stop
`ActionController::Parameters` to inherit from `HashWithIndifferentAccess`
in the next minor release.
*Prem Sichanugrist*
* Deprecated TagAssertions.
*Kasper Timm Hansen*
* Use the Active Support JSON encoder for cookie jars using the `:json` or
`:hybrid` serializer. This allows you to serialize custom Ruby objects into
cookies by defining the `#as_json` hook on such objects.
Fixes #16520.
*Godfrey Chan*
* Add `config.action_dispatch.cookies_digest` option for setting custom
digest. The default remains the same - 'SHA1'.
*Łukasz Strzałkowski*
* Move `respond_with` (and the class-level `respond_to`) to
the `responders` gem.
*José Valim*
* When your templates change, browser caches bust automatically.
New default: the template digest is automatically included in your ETags.
When you call `fresh_when @post`, the digest for `posts/show.html.erb`
is mixed in so future changes to the HTML will blow HTTP caches for you.
This makes it easy to HTTP-cache many more of your actions.
If you render a different template, you can now pass the `:template`
option to include its digest instead:
fresh_when @post, template: 'widgets/show'
Pass `template: false` to skip the lookup. To turn this off entirely, set:
config.action_controller.etag_with_template_digest = false
*Jeremy Kemper*
* Remove deprecated `AbstractController::Helpers::ClassMethods::MissingHelperError`
in favor of `AbstractController::Helpers::MissingHelperError`.
*Yves Senn*
* Fix `assert_template` not being able to assert that no files were rendered.
*Guo Xiang Tan*
* Extract source code for the entire exception stack trace for
better debugging and diagnosis.
*Ryan Dao*
* Allows ActionDispatch::Request::LOCALHOST to match any IPv4 127.0.0.0/8
loopback address.
*Earl St Sauver*, *Sven Riedel*
* Preserve original path in `ShowExceptions` middleware by stashing it as
`env["action_dispatch.original_path"]`
`ActionDispatch::ShowExceptions` overwrites `PATH_INFO` with the status code
for the exception defined in `ExceptionWrapper`, so the path
the user was visiting when an exception occurred was not previously
available to any custom exceptions_app. The original `PATH_INFO` is now
stashed in `env["action_dispatch.original_path"]`.
*Grey Baker*
* Use `String#bytesize` instead of `String#size` when checking for cookie
overflow.
*Agis Anastasopoulos*
* `render nothing: true` or rendering a `nil` body no longer add a single
space to the response body.
The old behavior was added as a workaround for a bug in an early version of
Safari, where the HTTP headers are not returned correctly if the response
body has a 0-length. This is been fixed since and the workaround is no
longer necessary.
Use `render body: ' '` if the old behavior is desired.
See #14883 for details.
*Godfrey Chan*
* Prepend a JS comment to JSONP callbacks. Addresses CVE-2014-4671
("Rosetta Flash")
*Greg Campbell*
* Because URI paths may contain non US-ASCII characters we need to force
the encoding of any unescaped URIs to UTF-8 if they are US-ASCII.
This essentially replicates the functionality of the monkey patch to
URI.parser.unescape in active_support/core_ext/uri.rb.
Fixes #16104.
*Karl Entwistle*
* Generate shallow paths for all children of shallow resources.
Fixes #15783.
*Seb Jacobs*
* JSONP responses are now rendered with the `text/javascript` content type
when rendering through a `respond_to` block.
Fixes #15081.
*Lucas Mazza*
* Add `config.action_controller.always_permitted_parameters` to configure which
parameters are permitted globally. The default value of this configuration is
`['controller', 'action']`.
*Gary S. Weaver*, *Rafael Chacon*
* Fix env['PATH_INFO'] missing leading slash when a rack app mounted at '/'.
Fixes #15511.
*Larry Lv*
* ActionController::Parameters#require now accepts `false` values.
Fixes #15685.
*Sergio Romano*
* With authorization header `Authorization: Token token=`, `authenticate` now
recognize token as nil, instead of "token".
Fixes #14846.
*Larry Lv*
* Ensure the controller is always notified as soon as the client disconnects
during live streaming, even when the controller is blocked on a write.
*Nicholas Jakobsen*, *Matthew Draper*
* Routes specifying 'to:' must be a string that contains a "#" or a rack
application. Use of a symbol should be replaced with `action: symbol`.
Use of a string without a "#" should be replaced with `controller: string`.
*Aaron Patterson*
* Fix URL generation with `:trailing_slash` such that it does not add
a trailing slash after `.:format`
*Dan Langevin*
* Build full URI as string when processing path in integration tests for
performance reasons.
*Guo Xiang Tan*
* Fix `'Stack level too deep'` when rendering `head :ok` in an action method
called 'status' in a controller.
Fixes #13905.
*Christiaan Van den Poel*
* Add MKCALENDAR HTTP method (RFC 4791).
*Sergey Karpesh*
* Instrument fragment cache metrics.
Adds `:controller`: and `:action` keys to the instrumentation payload
for the `*_fragment.action_controller` notifications. This allows tracking
e.g. the fragment cache hit rates for each controller action.
*Daniel Schierbeck*
* Always use the provided port if the protocol is relative.
Fixes #15043.
*Guilherme Cavalcanti*, *Andrew White*
* Moved `params[request_forgery_protection_token]` into its own method
and improved tests.
Fixes #11316.
*Tom Kadwill*
* Added verification of route constraints given as a Proc or an object responding
to `:matches?`. Previously, when given an non-complying object, it would just
silently fail to enforce the constraint. It will now raise an `ArgumentError`
when setting up the routes.
*Xavier Defrang*
* Properly treat the entire IPv6 User Local Address space as private for
purposes of remote IP detection. Also handle uppercase private IPv6
addresses.
Fixes #12638.
*Caleb Spare*
* Fixed an issue with migrating legacy json cookies.
Previously, the `VerifyAndUpgradeLegacySignedMessage` assumes all incoming
cookies are marshal-encoded. This is not the case when `secret_token` is
used in conjunction with the `:json` or `:hybrid` serializer.
In those case, when upgrading to use `secret_key_base`, this would cause a
`TypeError: incompatible marshal file format` and a 500 error for the user.
Fixes #14774.
*Godfrey Chan*
* Make URL escaping more consistent:
1. Escape '%' characters in URLs - only unescaped data should be passed to URL helpers
2. Add an `escape_segment` helper to `Router::Utils` that escapes '/' characters
3. Use `escape_segment` rather than `escape_fragment` in optimized URL generation
4. Use `escape_segment` rather than `escape_path` in URL generation
For point 4 there are two exceptions. Firstly, when a route uses wildcard segments
(e.g. `*foo`) then we use `escape_path` as the value may contain '/' characters. This
means that wildcard routes can't be optimized. Secondly, if a `:controller` segment
is used in the path then this uses `escape_path` as the controller may be namespaced.
Fixes #14629, #14636 and #14070.
*Andrew White*, *Edho Arief*
* Add alias `ActionDispatch::Http::UploadedFile#to_io` to
`ActionDispatch::Http::UploadedFile#tempfile`.
*Tim Linquist*
* Returns null type format when format is not know and controller is using `any`
format block.
Fixes #14462.
*Rafael Mendonça França*
* Improve routing error page with fuzzy matching search.
*Winston*
* Only make deeply nested routes shallow when parent is shallow.
Fixes #14684.
*Andrew White*, *James Coglan*
* Append link to bad code to backtrace when exception is `SyntaxError`.
*Boris Kuznetsov*
* Swapped the parameters of assert_equal in `assert_select` so that the
proper values were printed correctly.
Fixes #14422.
*Vishal Lal*
* The method `shallow?` returns false if the parent resource is a singleton so
we need to check if we're not inside a nested scope before copying the :path
and :as options to their shallow equivalents.
Fixes #14388.
*Andrew White*
* Make logging of CSRF failures optional (but on by default) with the
`log_warning_on_csrf_failure` configuration setting in
`ActionController::RequestForgeryProtection`.
*John Barton*
* Fix URL generation in controller tests with request-dependent
`default_url_options` methods.
*Tony Wooster*
