* Add `Vary: Accept` header when renderingst00122019-07-261-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem description (quoted from @rafaelfranca's excellent explanation in https://github.com/rails/jquery-ujs/issues/318#issuecomment-88129005): > Let say that we requested /tasks/1 using Ajax, and the previous page has the same url. When we click the back button the browser tries to get the response from its cache and it gets the javascript response. With vary we "fix" this behavior because we are telling the browser that the url is the same but it is not from the same type what will skip the cache. And there's a Rails issue discussing about this problem as well https://github.com/rails/rails/issues/25842 Also, according to [RFC 7231 7.1.4](https://tools.ietf.org/html/rfc7231#section-7.1.4) > An origin server SHOULD send a Vary header field when its algorithm > for selecting a representation varies based on aspects of the request > message other than the method and request target we should add `Vary: Accept` header when determining content based on the `Accept` header. Although adding such header by default could cause unnecessary cache invalidation. But this PR only adds the header if: - The format param is not provided - The request is a `xhr` request - The request has accept headers and the headers are valid So if the user - sends request with explicit format, like `/users/1.json` - or sends a normal request (non xhr) - or doesn't specify accept headers then the header won't be added. See the discussion in https://github.com/rails/rails/issues/25842 and https://github.com/rails/rails/pull/36213 for more details.
* Enable `Layout/EmptyLinesAroundAccessModifier` copRyuta Kamizono2019-06-132-2/+0
| | | | | | | | | | | We sometimes say "✂️ newline after `private`" in a code review (e.g. https://github.com/rails/rails/pull/18546#discussion_r23188776, https://github.com/rails/rails/pull/34832#discussion_r244847195). Now `Layout/EmptyLinesAroundAccessModifier` cop have new enforced style `EnforcedStyle: only_before` (https://github.com/rubocop-hq/rubocop/pull/7059). That cop and enforced style will reduce the our code review cost.

* Add `Style/RedundantFreeze` to remove redudant `.freeze`Yasuo Honda2018-09-292-2/+2
| | | | | | | | | | | | | | | | | | | | | Since Rails 6.0 will support Ruby 2.4.1 or higher `# frozen_string_literal: true` magic comment is enough to make string object frozen. This magic comment is enabled by `Style/FrozenStringLiteralComment` cop. * Exclude these files not to auto correct false positive `Regexp#freeze` - 'actionpack/lib/action_dispatch/journey/router/utils.rb' - 'activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb' It has been fixed by https://github.com/rubocop-hq/rubocop/pull/6333 Once the newer version of RuboCop released and available at Code Climate these exclude entries should be removed. * Replace `String#freeze` with `String#-@` manually if explicit frozen string objects are required - 'actionpack/test/controller/test_case_test.rb' - 'activemodel/test/cases/type/string_test.rb' - 'activesupport/lib/active_support/core_ext/string/strip.rb' - 'activesupport/test/core_ext/string_ext_test.rb' - 'railties/test/generators/actions_test.rb'
* Allow helpers to be deferred until the routes have been finalizedAaron Patterson2018-09-251-5/+2
| | | | | | | | | | | | | | | | ActiveStorage::BaseController subclasses ActionController::Base. ActionController::Base has an "inherited" hook set that includes the routing helpers to any subclass of AC::Base. Since ActiveStorage::BaseController is a subclass of AC::Base, it will get routing helpers included automatically. Unfortunately, when the framework is eagerly loaded, ActiveStorage::BaseController is loaded *before* the applications routes are loaded which means it attempts to include an "in flight" module so it gets an exception. This commit allows a class that's interested in being extended with routing helpers register itself such that when the routes are finalized, it will get the helpers included. If the routes are already finalized, then the helpers get included immediately.
* Fewer allocations in caching/fragments.rbschneems2018-08-291-1/+5
| | | | Instead of using a splat on the head and tail we can mutate the array by flattening 1 level. We get further savings by not allocating another via `compact` but instead by using `compact!`

* Add cancellation info to before filter docsZachary Wasserman2018-03-141-0/+12
| | | | | | | | | It is important for users to know that a render or redirect in a "before" filter causes the action to be cancelled. This was addressed in the guide, but not the API docs (http://guides.rubyonrails.org/action_controller_overview.html#filters). [ci skip]

* Keep `:api: plugin` methods in the doc [ci skip]Ryuta Kamizono2017-10-201-3/+3
| | | | | | | `:api:` tag was removed in 5349f231 since RDoc doesn't support `:api:` tag. But those methods are not private API, they are public API for renderers. The renderers should be able to know that they can override this method.

* Remove `:api:` tag that has leaked on the doc directly [ci skip]Ryuta Kamizono2017-09-302-15/+3
| | | | | | | | | | | | Currently `:api:` tag has leaked on the doc directly since RDoc doesn't support `:api:` tag directive. http://api.rubyonrails.org/v5.1/classes/AbstractController/Rendering.html So `:api: private` doesn't work as expected. We are using `:nodoc:` for the purpose. Related #13989.

* Freeze fragment cache related instrument name.Stan Lo2017-02-071-1/+1
| | | | | | | | | | | | | ActionMailer::Base#instrument_name and ActionController::Base#instrument_name will be frequently called once caching is enabled. So it's better to freeze them instead of create new string on every call. Also, the instrument name in #instrument_fragment_cache will usually be "write_fragment.action_controller" or "read_fragment.action_controller". So freezing them might also gain some performance improvement. We have done something like this in other places: https://github.com/rails/rails/blob/master/actionview/lib/action_view/template.rb#L348
* Change ActionView ERB Handler from Erubis to ErubiJeremy Evans2017-01-251-2/+0
| | | | | | | | | | | | | | | | | | | | | | | Erubi offers the following advantages for Rails: * Works with ruby's --enable-frozen-string-literal option * Has 88% smaller memory footprint * Does no freedom patching (Erubis adds a method to Kernel) * Has simpler internals (1 file, <150 lines of code) * Has an open development model (Erubis doesn't have a public source control repository or bug tracker) * Is not dead (Erubis hasn't been updated since 2011) Erubi is a simplified fork of Erubis that contains just the parts that are generally needed (which includes the parts that Rails uses). The only intentional difference in behavior is that it does not include support for <%=== tags for debug output. That could be added to the ActionView ERB handler if it is desired. The Erubis template handler remains in a deprecated state so that code that accesses it directly does not break. It can be removed after Rails 5.1.
* Extract variant setter to process methodJon Moss2017-01-021-4/+4
| | | | | | | Provide an API interface similar to how format is handled in Controllers. In situations where variants are not needed (ex: in Action Mailer) the method will simply trigger a no-op, and will not affect end users.

* code gardening: removes redundant selfsXavier Noria2016-08-081-1/+1

Because other classes also includes CacheHelper but don't have is attribute Use @log_payload_for_partial_reder instead of #log_payload to carry ActionView's payload.
