This reverts commit 5bbb2a6, reversing
changes made to f9e4906.

Reason: Since #36866, we use `azure-storage-blob` gem. So the original
description is correct.

…hods

Call `MonitorMixin` initializer before use methods provided by `MonitorMixin`

…orMixin`

`MonitorMixin` setup internal variables in `initialize`, so need to call
that before use.
`ActionController::Live::Buffer` only use methods that do not depend on those
internal variables, so works expertly.

But since Ruby 2.7, methods that were not originally the case also depend on
internal variables. As a result, some tests fail in Ruby 2.7.

I'm not sure if this should be considered Ruby incompatible, but I fixed
this because its usage is wrong.

Fix broken check on GitHub actions

Without it, it seems to be an error trying to install an older version.

…_in_generating_guides

Suppress deprecation warning in generating the guide `index.html`

…-collision

Fix the collision check for the scaffold generator

Cache gems for GitHub Actions

`bin/yarn` exec `"yarn"` rather than `"yarnpkg"`

This test class uses `ActiveRecord::IllegalMigrationNameError`.
So without this require, tests fail randomly.

Update for `Time#inspect`

This broke CI. https://buildkite.com/rails/rails/builds/63708

The option name is `enroll` since f1f5024.

System tests depend on Capybara 3.26 or newer. Ref: #36615.

Don't use Process#clock_gettime CLOCK_PROCESS_CPUTIME_ID on Solaris

Correctly classify the files and directories that pass to watcher

Add title tag to mailer previews

Currently, autoload paths pass to the watcher as directories. If using evented
watcher, this possibly pass as it is to `Listen`.
But autoload paths include files and `Listen` raise an error when was passed
file. So, it is necessary to classify files and directories correctly.

Fixes #37011.

Because `FeaturePolicy::Middleware` is not loaded in API only apps.
Ref: https://github.com/rails/rails/blob/646dd8c51fc438bf935d4192ba0479e439c1ec54/railties/lib/rails/application/default_middleware_stack.rb#L69-L72

Address `DEPRECATED: Use assert_nil if expecting nil`

This fixes the following warnings.

```
actionmailer/test/base_test.rb:272: warning: method redefined; discarding old welcome
actionmailer/test/base_test.rb:260: warning: previous definition of welcome was here
```

To avoid a deprecation warning.

It causes unexpected results when running tests in parallel.

…en after `/' operator"

`Messages::Rotator` has `@on_rotation` not `@rotation`.

…che_versioning

Add mention about `active_record.collection_cache_versioning` to the `new_framework_defaults.rb`

…`new_framework_defaults.rb`

All other recommended new configurations that set in `load_defaults` are
already mentioned in `new_framework_defaults.rb`.
So `active_record.collection_cache_versioning` should also be mentioned.

…ne_to_gemfile_insertion

Add a newline at the end of a Gemfile when it doesn't end with a newline

Add support for script-src-attr / elem and style-src-attr / elem directives

…ctives

These directives can be used in Chrome 75.
