The current code base is not uniform. After some discussion,
we have chosen to go with double quotes by default.

Setup default session store internally, no longer through an initializer
|
| |
| |
| |
| |
| |
| |
| |
| |
| |
| |
| |
| |

initializer
- 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.

People who deploy to containers or other places where they might have some sort of a log wrapping service use stdout. With this change new rails apps can be configured to output to STDOUT via setting `RAILS_LOG_TO_STDOUT` to any value. This allows container images or services to set the value for all apps without having to modify configuration for each application. If an app wants to opt out, they can either delete from the env hash, or remove that configuration.

Now that AC::Parameters is no longer a Hash, it shouldn't look like a hash.

In high volume applications it can be very difficult to figure out what is happening in logs because each request is not easily identified. For example 3 requests could look something like this:
```
Started GET "/" for 72.48.77.213 at 2016-01-06 20:30:21 +0000
Rendered welcome/index.html.erb within layouts/application (0.1ms)

Processing by WelcomeController#index as HTML
Completed 200 OK in 5ms (Views: 3.8ms | ActiveRecord: 0.0ms)
```
The `:request_id` log tag ensures that each request is tagged with a unique identifier. While they are still interleaved it is possible to figure out which lines belong to which requests. Like:
```
[c6034478-4026-4ded-9e3c-088c76d056f1] Started GET "/" for 72.48.77.213 at 2016-01-06 20:30:21 +0000

```
Now if you have the logs and you find this unique ID you can filter to only look at information from that request. So a filtered log output would be very clear:
```
[c6034478-4026-4ded-9e3c-088c76d056f1] Started GET "/" for 72.48.77.213 at 2016-01-06 20:30:21 +0000
[c6034478-4026-4ded-9e3c-088c76d056f1] Rendered welcome/index.html.erb within layouts/application (0.1ms)
[c6034478-4026-4ded-9e3c-088c76d056f1] Processing by WelcomeController#index as HTML
[c6034478-4026-4ded-9e3c-088c76d056f1] Completed 200 OK in 5ms (Views: 3.8ms | ActiveRecord: 0.0ms)
```
In addition to this benefit the `:request_id` can be set via the `X-Request-ID` header so that the same request could be traced between multiple components. For example a request comes in Nginx (or another load balancer) could assign a request id. As the load balancer processes the request I can log using that id, then when the request is passed on to Rails, the same id is used. That way if a problem is determined to be not caused in Rails it could be traced back to other components with the same ID. You can set a value in nginx for example using something like this:
```
location / {
proxy_pass http://upstream;
proxy_set_header X-Request-Id $pid-$msec-$remote_addr-$request_length;
}
# http://stackoverflow.com/questions/17748735/setting-a-trace-id-in-nginx-load-balancer
```
Heroku sets this header value so problems like timeouts that are logged by like router can be traced back to specific request within the application.
Whether you are using components that are setting request ID or not, all production applications can benefit from the additional debugging information of having a unique identifier for all requests. This change will only affect new applications, anyone can opt out by commenting or removing the line in `config/production.rb`.

It's pretty common for folks to monkey patch `ActiveRecord::Base` to
work around an issue or introduce extra functionality. Instead of
shoving even more stuff in `ActiveRecord::Base`, `ApplicationRecord` can
hold all those custom work the apps may need.
Now, we don't wanna encourage all of the application models to inherit
from `ActiveRecord::Base`, but we can encourage all the models that do,
to inherit from `ApplicationRecord`.
Newly generated applications have `app/models/application_record.rb`
present by default. The model generators are smart enough to recognize
that newly generated models have to inherit from `ApplicationRecord`,
but only if it's present.

That would make possible to use it with action cable configuration.

Apart from specific versioning support, our tests should focus on the
behaviour of whatever version they're accompanying, regardless of when
they were written.
Application code should *not* do this.

As discussed in https://github.com/rails/rails/pull/19135#issuecomment-153385986.
Replaces `serve_static_files` to unify the static options under the `public_file_server` wing.
Deprecates `serve_static_files` accessors, but make them use the newer config internally.

If `SECRET_KEY_BASE` or other `secret` gets passed as other then string
we need to raise `ArgumentError` to know that it's a wrong argument.

Add basic support for access control headers to ActionDispatch::Static
|
| |
| |
| |
| |
| |
| |
| |
| |
| |
| |
| |
| |
| |
| |

Now ActionDispatch::Static can accept HTTP headers so that developers
will have control of returning arbitrary headers like
'Access-Control-Allow-Origin' when a response is delivered. They can
be configured through `#config.public_file_server.headers`:
config.public_file_server.headers = {
"Cache-Control" => "public, max-age=60",
"Access-Control-Allow-Origin" => "http://rubyonrails.org"
}
Also deprecate `config.static_cache_control` in favor of
`config.public_file_server.headers`.

* Move `app/assets/manifest.js` to `app/assets/config/manifest.js`.
Avoid the suggestion that you can/should deep-link `stylesheets/foo`.
* Pull in all toplevel stylesheets and JavaScripts, not just
`application.js` and `.css`. Demonstrate how to use `link_directory`
with a specified `.js`/`.css` type.
* Fix RAILS_ENV handling in assets tests.
* Shush warnings spam from third-party libs that distract from tests.
