Generally followed the pattern for https://github.com/rails/rails/pull/32034
* Removes needless CI configs for 2.4
* Targets 2.5 in rubocop
* Updates existing CHANGELOG entries for fewer merge conflicts
* Removes Hash#slice extension as that's inlined on Ruby 2.5.
* Removes the need for send on define_method in MethodCallAssertions.
Since MySQL 5.7.9, the `innodb_default_row_format` option defines the
default row format for InnoDB tables. The default setting is `DYNAMIC`.
The row format is required for indexing on `varchar(255)` with `utf8mb4`
columns.
As long as using MySQL 5.6, CI won't be passed even if MySQL server
setting is properly configured the same as MySQL 5.7
(`innodb_file_per_table = 1`, `innodb_file_format = 'Barracuda'`, and
`innodb_large_prefix = 1`) since InnoDB table is created as the row
format `COMPACT` by default on MySQL 5.6, therefore indexing on string
with `utf8mb4` columns aren't succeeded.
Making `ROW_FORMAT=DYNAMIC` create table option by default for legacy
MySQL version would mitigate the indexing issue on the user side, and it
makes CI would be passed on MySQL 5.6 which is configured properly.
Running `./bin/rails generate mailbox application --no-test-framework` generates:
```
class ApplicationMailbox < ApplicationMailbox
def process
end
end
```
which is not correct for the application mailbox. It shouldn't
respond to process but it should contain a routing hint.
Generally generators aren't meant to be used like the previous commit.
The mailbox generator can certainly add in the ApplicationMailbox
if missing, but it shouldn't be called with "application" as an argument.
Also adds back auto inserting an `ingress` config line in
`config/environmnets/production.rb`.
Fixes#13.

* Add option to set parallel test worker count to the physical core count of the machine
Also, use the physical core count of the machine as
the default number of workers, and generate the `test_helper.rb` file
with `parallelize(workers: :number_of_processors)`
Closes#34734
* Ensure that we always test parallel testing
Since #34734 we decided to use the physical core count of the machine as
the default number of workers in the parallel testing, we need to
ensure that some tests use at least 2 workers because we could
run those tests on VM that has only 1 physical core.
It also fixes tests failures on the CI since Travis server we are using
has only one physical core.

`EventedFileUpdateChecker` will search the parent directory if the
specified directory does not exist.
Since `test/mailers/previews` is included in the watch target by default,
if there is no test directory (e.g. using `rspec`), the Rails root directory
will be included in the watch target.
```
$ rails new app
$ cd app
$ ./bin/rails r "p Rails.application.reloaders.last.send(:directories_to_watch).include?(Rails.root)"
false
$ rm -rf test
$ ./bin/rails r "p Rails.application.reloaders.last.send(:directories_to_watch).include?(Rails.root)"
true
```
This causes `node_modules` to be included in watch target. Adding parent
directories to watch target may include unexpected directories.
In order to avoid this, fixed that parents of nonexistent directories are
not added to the watch targets, instead checking that the directory
exists when checking changes.

* Extend documentation of `ActiveSupport::Notifications.subscribe`
Add mention that a block with only one argument passed to the method
will yield an event object.
Related to #33451
* Emphasize that `SubscribeEventObjects` is a test class by adding suffix `Test`
… by switching the initialzation of an appropriate response parser
in `ActionDispatch::TestResponse` from eagerly to lazily.
By doing so, the response parser can be correctly set for
`ActionController::TestCase`, which doesn't include
the content type header in the constructor but only sets it at
a later time.
Fixes#34676.
The ActionDispatch::HostAuthorization is a new middleware that prevent
against DNS rebinding and other Host header attacks. By default it is
included only in the development environment with the following
configuration:
Rails.application.config.hosts = [
IPAddr.new("0.0.0.0/0"), # All IPv4 addresses.
IPAddr.new("::/0"), # All IPv6 addresses.
"localhost" # The localhost reserved domain.
]
In other environments, `Rails.application.config.hosts` is empty and no
Host header checks will be done. If you want to guard against header
attacks on production, you have to manually permit the allowed hosts
with:
Rails.application.config.hosts << "product.com"
The host of a request is checked against the hosts entries with the case
operator (#===), which lets hosts support entries of type RegExp,
Proc and IPAddr to name a few. Here is an example with a regexp.
# Allow requests from subdomains like `www.product.com` and
# `beta1.product.com`.
Rails.application.config.hosts << /.*\.product\.com/
A special case is supported that allows you to permit all sub-domains:
# Allow requests from subdomains like `www.product.com` and
# `beta1.product.com`.
Rails.application.config.hosts << ".product.com"
If a klass has acceptance validation and then
`klass.undefine_attribute_methods` is happened before an attribute
method is called, infinit loop is caused on the `method_missing` defined
by the `LazilyDefineAttributes`.
https://travis-ci.org/rails/rails/jobs/467053984#L1409
To prevent the infinit loop, the `method_missing` should ensure
`klass.define_attribute_methods`.
