This reverts commit 4973704b, reversing
changes made to 78edeb33.

Now the schema dumper by default doesn't align the types and arguments
in the ruby format anymore.

- It is Action Controller config, not Action View.

Follow up to fe859a54

Implement naive partial caching mechanism.

Add test for LogSubscriber

Use ActionView::Base#log_payload to store log_subscriber's payload, so we can pass cache result into it.

Fixed tests

Remove useless settings

Check if #log_payload exists before calling it. Because other classes also includes CacheHelper but don't have is attribute

Use @log_payload_for_partial_reder instead of #log_payload to carry ActionView's payload.

Update test's hash syntax

Add configuration to enable/disable fragment caching logging

Remove unless test and add new test to ensure cache info won't effect next rendering's log

Move :enable_fragment_cache_logging config from ActionView to ActionPack

Apply new config to tests

Update actionview's changelog

Update configuration guide

Improve actionview's changelog

Refactor PartialRenderer#render and log tests

Mute subscriber's log instead of disabling instrumentation.

Fix typo, remove useless comment and use new hash syntax

Improve actionpack's log_subscriber test

Fix rebase mistake

Apply new config to all caching intstrument actions

That file has been removed and replaced with new_framework_defaults.rb

- By default the session store will be set to cookie store with
  application name as session key.
- Older apps are not affected as they will have the session store
  initializer generated by Rails in older versions, and Rails will not
  overwrite the session store if it is already set or disabled.
- But new apps will not have the initializer, instead the session store
  will be set to cookie store by default.
- Based on comment by DHH here - https://github.com/rails/rails/issues/25181#issuecomment-222312764.

Follow up to #24436

- Also to_time_preserves_timezone config should be false for older apps getting upgraded to Rails 5 [ci skip]

This will make easier to applications that rely on having const_missing
hooks in production upgrade to Rails 5.

This option is going to be remove in the future and the default behavior
will be to disable the dependency loading.

SSL_set_verify(3) explains:

SSL_VERIFY_FAIL_IF_NO_PEER_CERT
  Server mode: if the client did not return a certificate, the TLS/SSL
handshake is immediately terminated with a "handshake failure" alert.
This flag must
  be used together with SSL_VERIFY_PEER.

  Client mode: ignored

SSL_VERIFY_CLIENT_ONCE
  Server mode: only request a client certificate on the initial TLS/SSL
handshake. Do not ask for a client certificate again in case of a
renegotiation.
  This flag must be used together with SSL_VERIFY_PEER.

  Client mode: ignored

The SMTP connection here uses a OpenSSL socket in client mode,
suggesting invalid/ignored flags is rather misleading.

The `ActiveRecord::ConnectionAdapters::ConnectionManagement` and `ActiveRecord::QueryCache` middlewares were removed with `Executor` addition on d3c9d808
Removes traces and reference of these from all places.

Document config.action_dispatch.ignore_accept_header and config.action_dispatch.x_sendfile_header in configuring guide

Lets be consistent in the usage of true/false across this guide. It should be quoted as how other config options are. They are already quoted at many places. This change, makes this usage consistent. Note that, this is quoting literal values true and false, not truthy values

[ci skip]

Guides should be updated because ActionDispatch::LoadInterlock was replaced with
ActionDispatch::Executor at #23807.

Some configuration options started with a capital letter indicating the beginning of a sentence, which didn't makes sense without the colons. Similarly, some were missing periods at the end of their descriptions. [ci skip]
