Check for any non-UTF8 characters in path parameters at the point they're
set in `env`. Previously they were checked for when used to get a controller
class, but this meant routes that went directly to a Rack app, or skipped
controller instantiation for some other reason, had to defend against
non-UTF8 characters themselves.
The `ActionDispatch::Static` middleware is used low down in the stack to serve
static assets before doing much processing. Since it's called from so low in
the stack, we don't have access to the request ID at this point, and generally
won't have any exception handling defined (by default `ShowExceptions` is added
to the stack quite a bit higher and relies on logging and request ID).
Before 8f27d6036a
this middleware would ignore unknown HTTP methods, and an exception about these
would be raised higher in the stack. After that commit, however, that exception
will be raised here.
If we want to keep `ActionDispatch::Static` so low in the stack (I think we do)
we should suppress the `ActionController::UnknownHttpMethod` exception here,
and instead let it be raised higher up the stack, once we've had a chance to
define exception handling behaviour.
This PR updates `ActionDispatch::Static` so it passes `Rack::Request` objects to
`ActionDispatch::FileHandler`, which won't raise an
`ActionController::UnknownHttpMethod` error. If an unknown method is
passed, it should exception higher in the stack instead, once we've had a
chance to define exception handling behaviour.`
Rack [recently](7e7a389044)
moved the namespace of its `ParameterTypeError` and `InvalidParameterError`
errors. Whilst an alias for the old name was added, the logic in
`ActionDispatch::ExceptionWrapper` was still broken by this change, since it
relies on the class name.
This PR updates `ActionDispatch::ExceptionWrapper` to handle the Rack 2.0
namespaced errors correctly. We no longer need to worry about the old names,
since Rails specifies Rack ~> 2.0.
It is a common pattern in the Rails community that when people want to
:xa
use any kind of helper that is defined inside app/helpers they includes
the helper module inside the controller like:
module UserHelper
def my_user_helper
# ...
end
end
class UsersController < ApplicationController
include UserHelper
def index
render inline: my_user_helper
end
end
This has problem because the helper can't access anything that is
defined in the view level context class.
Also all public methods of the helper become available in the controller
what can lead to undesirable methods being routed and behaving as
actions.
Also if you helper depends on other helpers or even Action View helpers
you need to include each one of these dependencies in your controller
otherwise your helper is not going to work.
We already have a helpers proxy at controller class level but that proxy
doesn't have access to the instance variables defined in the
controller.
With this new instance level helper proxy users can reuse helpers in the
controller without having to include the modules and with access to
instance variables defined in the controller.
class UsersController < ApplicationController
def index
render inline: helpers.my_user_helper
end
end
- skip calling helper_method if it's not there: if we don't have helpers, we needn't define one.
- tests that an api controller can include and use ActionController::Cookies
* Introduce `Response#strong_etag=` and `#weak_etag=` and analogous options
for `fresh_when` and `stale?`. `Response#etag=` sets a weak ETag.
Strong ETags are desirable when you're serving byte-for-byte identical
responses that support Range requests, like PDFs or videos (typically
done by reproxying the response from a backend storage service).
Also desirable when fronted by some CDNs that support strong ETags
only, like Akamai.
* No longer strips quotes (`"`) from ETag values before comparing them.
Quotes are significant, part of the ETag. A quoted ETag and an unquoted
one are not the same entity.
* Support `If-None-Match: *`. Rarely useful for GET requests; meant
to provide some optimistic concurrency control for PUT requests.

This updates the 5.0 release notes guide to reflect changes that
happened after beta1 has been released.
I'll sync the other changelogs later today but I'll push this batch to
prevent against cumbersome merge conflicts.
This method will only be added when used with Ruby 2.3.0 or greater.
This method has the same behavior as `Hash#dig`, except it will convert
hashes to `ActionController::Parameters`, similar to `#[]` and `#fetch`.
After 9d378747326d26cf1afdac4433ead22967af0984 `ActionDispatch::IntegrationTest`
class is loaded and defined in all Rails environments, not only test but also
production. This is not-intended loading of a class which is only used in
test environment.
To prevent not-intended loading, add `ActiveSupport.run_load_hooks` to
`ActionDispatch::IntegrationTest` with `action_dispatch_integration_test` name
and use it in `ActionMailer`.
This reverts commit 22db455dbe9c26fe6d723cac0758705d9943ea4b, reversing
changes made to 40be61dfda1e04c3f306022a40370862e3a2ce39.
This finishes off what I meant to do in 6216a092ccfe6422f113db906a52fe8ffdafdbe6.
When a `respond_to` collector doesn't have a response, then a
`:no_content` response should be rendered. This brings the default
rendering behavior introduced by
https://github.com/rails/rails/issues/19036 to controller methods
employing `respond_to`
1. Conceptually revert #20276
The feature was implemented for the `responders` gem. In the end,
they did not need that feature, and have found a better fix (see
plataformatec/responders#131).
`ImplicitRender` is the place where Rails specifies our default
policies for the case where the user did not explicitly tell us
what to render, essentially describing a set of heuristics. If
the gem (or the user) knows exactly what they want, they could
just perform the correct `render` to avoid falling through to
here, as `responders` did (the user called `respond_with`).
Reverting the patch allows us to avoid exploding the complexity
and defining “the fallback for a fallback” policies.
2. `respond_to` and templates are considered exhaustive enumerations
If the user specified a list of formats/variants in a `respond_to`
block, anything that is not explicitly included should result
in an `UnknownFormat` error (which is then caught upstream to
mean “406 Not Acceptable” by default). This is already how it
works before this commit.
Same goes for templates – if the user defined a set of templates
(usually in the file system), that set is now considered exhaustive,
which means that “missing” templates are considered `UnknownFormat`
errors (406).
3. To keep API endpoints simple, the implicit render behavior for
actions with no templates defined at all (regardless of formats,
locales, variants, etc) are defaulted to “204 No Content”. This
is a strictly narrower version of the feature landed in #19036 and
#19377.
4. To avoid confusion when interacting in the browser, these actions
will raise an `UnknownFormat` error for “interactive” requests
instead. (The precise definition of “interactive” requests might
change – the spirit here is to give helpful messages and avoid
confusions.)
Closes#20666, #23062, #23077, #23564
[Godfrey Chan, Jon Moss, Kasper Timm Hansen, Mike Clark, Matthew Draper]
The longstanding convention in Rails is that if the :action parameter
is missing or nil then it defaults to 'index'. Up until Rails 5.0.0.beta1
this was handled slightly differently than other routing defaults by
deleting it from the route options and adding it to the recall parameters.
With the recent focus of removing unnecessary duplications this has
exposed a problem in this strategy - we are now mutating the request's
path parameters and causing problems for later url generation. This will
typically affect url_for rather a named url helper since the latter
explicitly pass :controller, :action, etc.
The fix is to add a default for :action in the route class if the path
contains an :action segment and no default is passed. This change also
revealed an issue with the parameterized part expiry in that it doesn't
follow a right to left order - as soon as a dynamic segment is required
then all other segments become required.
Fixes#23019.
Yesterday, when improving how `parsed_body` extracted a parser I wrote
77bbf1e. Then I thought that was too many changes in one commit
and broke it up locally... or so I thought.
When pushed the extra commits removed the changes! Wups!
In shame, lob those changes together here:
* 3b94c38 which meant to fix the CHANGELOG syntax error.
* 5007df5 which meant to mention `parsed_body` in the docs.
* 036a7a0 which meant to memoize the `parsed_body`.
Add two options: `-c` and `-g`.
`-g` option returns the urls name, verb and path fields that match the pattern.
`-c` option returns the urls for specific controller.
Fixes#18902, and Fixes#20420
