| | | | | | | * Since #18411, we started to inform about extracted gem (record_tag_helper) to developers who use `ActionView::Helpers::RecordTagHelper` 's methods. * Currently, it seems no problem that we don't have to support no longer.

| | | | | | | | | | | | `finalize_compiled_template_methods` Since we introduced default option for `class_attribute` and `mattr_accessor` family of methods and changed all occurrences of setting default values by using of `:default` option I think it would be fine to use `:default` option in order to set default value of `finalize_compiled_template_methods` since it expresses itself very well.

* Add `action_view.finalize_compiled_template_methods` config optionSimon Coffey2018-04-022-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | ActionView::Template instances compile their source to methods on the ActionView::CompiledTemplates module. To prevent leaks in development mode, where templates can frequently change, a finalizer is added that undefines these methods[1] when the templates are garbage-collected. This is undesirable in the test environment, however, as templates don't change during the life of the test. Moreover, the cost of undefining a method is proportional to the number of descendants a class or module has, since the method cache must be cleared for all descendant classes. As ActionView::CompiledTemplates is mixed into every ActionView::TestCase (or in RSpec suites, every view spec example group), it can end up with a very large number of descendants, and undefining its methods can become very expensive. In large test suites, this results in a long delay at the end of the test suite as all template finalizers are run, only for the process to then exit. To avoid this unnecessary cost, this change adds a config option, `action_view.finalize_compiled_template_methods`, defaulting to true, and sets it to false in the test environment only.

* Use consistent spacing in actionview helper docs [ci skip]Olivier Lacan2018-04-014-23/+23
| | | | | | | | The spacing in these comments is fairly inconsistent. Array argument contents are often separated with a space from the array literal brackets but in several cases the Hash literal curly braces are tangent to their contents which makes the documentation harder to read in some cases.

| * Add support for automatic nonce generation for Rails UJSAndrew White2018-02-193-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because the UJS library creates a script tag to process responses it normally requires the script-src attribute of the content security policy to include 'unsafe-inline'. To work around this we generate a per-request nonce value that is embedded in a meta tag in a similar fashion to how CSRF protection embeds its token in a meta tag. The UJS library can then read the nonce value and set it on the dynamically generated script tag to enable it to execute without needing 'unsafe-inline' enabled. Nonce generation isn't 100% safe - if your script tag is including user generated content in someway then it may be possible to exploit an XSS vulnerability which can take advantage of the nonce. It is however an improvement on a blanket permission for inline scripts. It is also possible to use the nonce within your own script tags by using `nonce: true` to set the nonce value on the tag, e.g <%= javascript_tag nonce: true do %> alert('Hello, World!'); <% end %> Fixes #31689.

Regarding the code using `if ... else ... end`, I think the coding style that Rails expects is as follows. ```ruby var = if cond a else b end ``` However, the current .rubocop.yml setting does not offense for the following code. ```ruby var = if cond a else b end ``` I think that the above code expects offense to be warned. Moreover, the layout by autocorrect is unnatural. ```ruby var = if cond a else b end ``` This PR adds a setting to .rubocop.yml to make an offense warning and autocorrect as expected by the coding style. And this change also fixes `case ... when ... end` together. Also this PR itself is an example that arranges the layout using `rubocop -a`. ### Other Information Autocorrect of `Lint/EndAlignment` cop is `false` by default. https://github.com/bbatsov/rubocop/blob/v0.51.0/config/default.yml#L1443 This PR changes this value to `true`. Also this PR has changed it together as it is necessary to enable `Layout/ElseAlignment` cop to make this behavior.
