* Changed the system tests to set Puma as default server only when the
user haven't specified manually another server.
*Guillermo Iguaran*
* Add secure `X-Download-Options` and `X-Permitted-Cross-Domain-Policies` to
default headers set.
*Guillermo Iguaran*
* Add headless firefox support to System Tests.
*bogdanvlviv*
* Changed the default system test screenshot output from `inline` to `simple`.
`inline` works well for iTerm2 but not everyone uses iTerm2. Some terminals like
Terminal.app ignore the `inline` and output the path to the file since it can't
render the image. Other terminals, like those on Ubuntu, cannot handle the image
inline, but also don't handle it gracefully and instead of outputting the file
path, it dumps binary into the terminal.
Commit 9d6e28 fixes this by changing the default for screenshot to be `simple`.
*Eileen M. Uchitelle*
* Register most popular audio/video/font mime types supported by modern browsers.
*Guillermo Iguaran*
* Fix optimized url helpers when using relative url root
Fixes #31220.
*Andrew White*
## Rails 5.2.0.beta2 (November 28, 2017) ##
* No changes.
## Rails 5.2.0.beta1 (November 27, 2017) ##
* Add DSL for configuring Content-Security-Policy header
The DSL allows you to configure a global Content-Security-Policy
header and then override within a controller. For more information
about the Content-Security-Policy header see MDN:
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy
Example global policy:
# config/initializers/content_security_policy.rb
Rails.application.config.content_security_policy do |p|
p.default_src :self, :https
p.font_src :self, :https, :data
p.img_src :self, :https, :data
p.object_src :none
p.script_src :self, :https
p.style_src :self, :https, :unsafe_inline
end
Example controller overrides:
# Override policy inline
class PostsController < ApplicationController
content_security_policy do |p|
p.upgrade_insecure_requests true
end
end
# Using literal values
class PostsController < ApplicationController
content_security_policy do |p|
p.base_uri "https://www.example.com"
end
end
# Using mixed static and dynamic values
class PostsController < ApplicationController
content_security_policy do |p|
p.base_uri :self, -> { "https://#{current_user.domain}.example.com" }
end
end
Allows you to also only report content violations for migrating
legacy content using the `content_security_policy_report_only`
configuration attribute, e.g;
# config/initializers/content_security_policy.rb
Rails.application.config.content_security_policy_report_only = true
# controller override
class PostsController < ApplicationController
self.content_security_policy_report_only = true
end
Note that this feature does not validate the header for performance
reasons since the header is calculated at runtime.
*Andrew White*
* Make `assert_recognizes` to traverse mounted engines
*Yuichiro Kaneko*
* Remove deprecated `ActionController::ParamsParser::ParseError`.
*Rafael Mendonça França*
* Add `:allow_other_host` option to `redirect_back` method.
When `allow_other_host` is set to `false`, the `redirect_back` will not allow redirecting from a
different host. `allow_other_host` is `true` by default.
*Tim Masliuchenko*
* Add headless chrome support to System Tests.
*Yuji Yaginuma*
* Add ability to enable Early Hints for HTTP/2
If supported by the server, and enabled in Puma this allows H2 Early Hints to be used.
The `javascript_include_tag` and the `stylesheet_link_tag` automatically add Early Hints if requested.
*Eileen M. Uchitelle*, *Aaron Patterson*
* Simplify cookies middleware with key rotation support
Use the `rotate` method for both `MessageEncryptor` and
`MessageVerifier` to add key rotation support for encrypted and
signed cookies. This also helps simplify support for legacy cookie
security.
*Michael J Coyne*
* Use Capybara registered `:puma` server config.
The Capybara registered `:puma` server ensures the puma server is run in process so
connection sharing and open request detection work correctly by default.
*Thomas Walpole*
* Cookies `:expires` option supports `ActiveSupport::Duration` object.
cookies[:user_name] = { value: "assain", expires: 1.hour }
cookies[:key] = { value: "a yummy cookie", expires: 6.months }
Pull Request: #30121
*Assain Jaleel*
* Enforce signed/encrypted cookie expiry server side.
Rails can thwart attacks by malicious clients that don't honor a cookie's expiry.
It does so by stashing the expiry within the written cookie and relying on the
signing/encrypting to vouch that it hasn't been tampered with. Then on a
server-side read, the expiry is verified and any expired cookie is discarded.
Pull Request: #30121
*Assain Jaleel*
* Make `take_failed_screenshot` work within engine.
Fixes #30405.
*Yuji Yaginuma*
* Deprecate `ActionDispatch::TestResponse` response aliases
`#success?`, `#missing?` & `#error?` are not supported by the actual
`ActionDispatch::Response` object and can produce false-positives. Instead,
use the response helpers provided by `Rack::Response`.
*Trevor Wistaff*
* Protect from forgery by default
Rather than protecting from forgery in the generated `ApplicationController`,
add it to `ActionController::Base` depending on
`config.action_controller.default_protect_from_forgery`. This configuration
defaults to false to support older versions which have removed it from their
`ApplicationController`, but is set to true for Rails 5.2.
*Lisa Ugray*
* Fallback `ActionController::Parameters#to_s` to `Hash#to_s`.
*Kir Shatrov*
* `driven_by` now registers poltergeist and capybara-webkit.
If poltergeist or capybara-webkit are set as drivers is set for System Tests,
`driven_by` will register the driver and set additional options passed via
the `:options` parameter.
Refer to the respective driver's documentation to see what options can be passed.
*Mario Chavez*
* AEAD encrypted cookies and sessions with GCM.
Encrypted cookies now use AES-GCM which couples authentication and
encryption in one faster step and produces shorter ciphertexts. Cookies
encrypted using AES in CBC HMAC mode will be seamlessly upgraded when
this new mode is enabled via the
`action_dispatch.use_authenticated_cookie_encryption` configuration value.
*Michael J Coyne*
* Change the cache key format for fragments to make it easier to debug key churn. The new format is:
views/template/action.html.erb:7a1156131a6928cb0026877f8b749ac9/projects/123
^template path ^template tree digest ^class ^id
*DHH*
* Add support for recyclable cache keys with fragment caching. This uses the new versioned entries in the
`ActiveSupport::Cache` stores and relies on the fact that Active Record has split `#cache_key` and `#cache_version`
to support it.
*DHH*
* Add `action_controller_api` and `action_controller_base` load hooks to be called in `ActiveSupport.on_load`
`ActionController::Base` and `ActionController::API` have differing implementations. This means that
the one umbrella hook `action_controller` is not able to address certain situations where a method
may not exist in a certain implementation.
This is fixed by adding two new hooks so you can target `ActionController::Base` vs `ActionController::API`
Fixes #27013.
*Julian Nadeau*
