* Action Mailer: Declarative exception handling with `rescue_from`.Jeremy Daer2016-05-151-12/+1
| | | | | | | | | | | | | | | | | | | | | | | Follows the same pattern as controllers and jobs. Exceptions raised in delivery jobs (enqueued by `#deliver_later`) are also delegated to the mailer's rescue_from handlers, so you can handle the DeserializationError raised by delivery jobs: ```ruby class MyMailer < ApplicationMailer rescue_from ActiveJob::DeserializationError do … end ``` ActiveSupport::Rescuable polish: * Add the `rescue_with_handler` class method so exceptions may be handled at the class level without requiring an instance. * Rationalize `exception.cause` handling. If no handler matches the exception, fall back to the handler that matches its cause. * Handle exceptions raised elsewhere. Pass `object: …` to execute the `rescue_from` handler (e.g. a method call or a block to instance_exec) against a different object. Defaults to `self`.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Adds #each_chunk to ActionDispatch::Response. it's a method which will be called by ActionDispatch::Response#each. - Make Response#each a proper method instead of delegating to @stream - In Live, instead of overriding #each, override #each_chunk. - `#each` should just spit out @str_body if it's already set - Adds #test_set_header_after_read_body_during_action to prove this fixes #23964 - Adds #test_each_isnt_called_if_str_body_is_written to ensure #each_chunk is not called when @str_body is available - Call `@response.sent!` in AC::TestCase's #perform so a test response acts a bit more like a real response. Makes test that call `#assert_stream_closed` pass again. - Additionally assert `#committed?` in `#assert_stream_closed` - Make test that was calling @response.stream.each pass again by calling @response.each instead.
* | Implement helpers proxy in controller instance levelRafael Mendonça França2016-05-052-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* | Move protected instance variable to the right placeRafael Mendonça França2016-05-051-3/+4
| | | | | | | | | | | | | | | | | | There were a lot of protected instance variables in AbsctractController::Rendering that were related to Action Controller and Action View. Moving to ActionController::Base's protected instance list we make it closer to where they are really defined.

* | quick edits on the AC::API RDoc [ci skip]Xavier Noria2016-04-051-19/+20
| | | | | | | | | | | | | | | | | | | | | | In particular, the fact that ApplicationController is the only one inheriting from AC::API is not a default. You could say at most that generators generate them that way, but the creation of controllers is something which is out of our control because programmers write controllers by hand. Instead, we can say that normally, conventionally, as in the majority of Rails apps, that is the actually the case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

Allows content-less APIs to use implicit responses without having to set a fake request format. This will need further attention. If you forget to redirect from a POST to a GET, you'll get a 204 No Content response that browsers will typically treat as… do nothing. It'll seem like the form just didn't work and knowing where to start debugging is non-obvious. On the flip side, redirecting from POST and others is the default, done everywhere, so it's less likely to be removed or otherwise missed. Alternatives are to do more explicit browser sniffing. Ref #23827.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was some subtle breakage caused by #18774, when we removed `#original_exception` in favor of `#cause`. However, `#cause` is automatically set by Ruby when raising an exception from a rescue block. With this change, we will use whichever handler has the highest priority (whichever call to `rescue_from` came last). In cases where the outer has lower precidence than the cause, but the outer is what should be handled, cause will need to be explicitly unset. Fixes #23925

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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]
