This helper creates a link tag with preload keyword that allows to
browser to initiate early fetch of resources. Additionally this send
Early Hints if supported.
See https://github.com/rails/rails/pull/30744/commits/59a02fb7bcbe68f26e1e7fdcec45c00c66e4a065
for more details about Early Hints.

Action Mailer context for example responds to request but don't have a

This will keep the behavior of an application with the defaults of a 4.2
or 5.0 application behaving the same when upgrading to 5.2.
|
| |
|
|
|
|
|
| |
The def with blank `()` was newly added in #31176, but we have not used
the blank `()` style in most part of our code base.
So I've enabled `Style/DefWithParentheses` to prevent to newly added the
code.

form_with_generates_ids
|
| | |
|
| |
|
|
|
| |
When the defaults being loaded are the 5.0 or 5.1 we disable generation
of ids with form_with.
|
| |
|
|
|
|
|
|
|
|
| |
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.`

### Summary
The [`:field_error_proc`](https://github.com/rails/rails/blob/master/actionview/lib/action_view/base.rb#L145) is responsible for decorating input tags that refer to attributes with errors. This default build-in rails feature wrap invalid form elements with additional markup: `<div class="field_with_errors">[…]</div>`.
* Fix for `field_error_proc` wraps form select `optgroup`
* Fix for `field_error_proc` wraps form select divider `option`
* Add tests for uncovered elements with errors
[Fixes #31088]
#### Test coverage
* `test_select_grouped_options_with_errors`
* `test_time_zone_select_with_priority_zones_and_errors`
#### Extend test coverage
* `test_collection_select_with_errors`
* `test_label_with_errors`
* `test_check_box_with_errors`
* `test_check_boxes_with_errors`
* `test_radio_button_with_errors`
* `test_radio_buttons_with_errors`
* `test_collection_check_boxes_with_errors`
* `test_collection_radio_buttons_with_errors`

`Kernel.#spawn` execute command via the shell if contains shell
metacharacters in the command.
In that case, return value of `spawn` is pid of the shell, not the server.
Therefore, just killing the pid will leave the process of server.
In order to correctly kill the server, send a signal to the process
group, not the process.

Since #24923, if use `select_tag` with `include_blank: true`, an empty
label is added.

Currently, the following error is shows only when run the test using
`bin/test`.
```
./bin/test -w test/template/log_subscriber_test.rb
Run options: --seed 17167
# Running:
/rails/actionview/test/template/log_subscriber_test.rb:34: warning: instance variable @defined_root not initialized
```
In `AVLogSubscriberTest`, if the `Rails.root` is not defined, define the
method and undef it in teardown.
https://github.com/rails/rails/blob/master/actionview/test/template/log_subscriber_test.rb#L21..L33
However, in `bin/test`, `Rails.root` is defined, which results in referring to
uninitialized variables and warnings.

Do a check if the 'rel' argument is passed in, and simply set it to
'nofollow' if 'rel' was not passed in. This prevents three string
allocations for each call to `link_to` in that scenario. In the scenario
where the 'rel' argument is passed in, performance is around the same as
before as the `key?` check is very fast.

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.
