|\ | | | | Add support for automatic nonce generation for Rails UJS
| * Add support for automatic nonce generation for Rails UJSAndrew White2018-02-192-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ### Summary This PR changes .rubocop.yml. 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.

* Change `form_with` to generates ids by defaultnpezza932017-11-256-35/+7
| | | | | | | | | | When `form_with` was introduced we disabled the automatic generation of ids that was enabled in `form_for`. This usually is not an good idea since labels don't work when the input doesn't have an id and it made harder to test with Capybara. You can still disable the automatic generation of ids setting `config.action_view.form_with_generates_ids` to `false.`

* Implement H2 Early Hints for Railseileencodes2017-10-041-4/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When puma/puma#1403 is merged Puma will support the Early Hints status code for sending assets before a request has finished. While the Early Hints spec is still in draft, this PR prepares Rails to allowing this status code. If the proxy server supports Early Hints, it will send H2 pushes to the client. This PR adds a method for setting Early Hints Link headers via Rails, and also automatically sends Early Hints if supported from the `stylesheet_link_tag` and the `javascript_include_tag`. Once puma supports Early Hints the `--early-hints` argument can be passed to the server to enable this or set in the puma config with `early_hints(true)`. Note that for Early Hints to work in the browser the requirements are 1) a proxy that can handle H2, and 2) HTTPS. To start the server with Early Hints enabled pass `--early-hints` to `rails s`. This has been verified to work with h2o, Puma, and Rails with Chrome. The commit adds a new option to the rails server to enable early hints for Puma.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Auto-generating content from the filename of an image is not suitable alternative text; alt text that isn't fully considered can be distracting and fatiguing for screen readers users (blind, low vision, dyslexic people). - Setting a filename fallback short circuits screen reader default behavior and configuration for blank descriptions. - Setting poor defaults also creates false negatives for accessibility linting and testing software, that makes it harder to improve application accessibility. *** - After this change, if authors leave images without alt text, screen readers will fallback to default behavior for missing alt text. - Also with this change, Automated linting and testing tools will correctly generate warnings.
