* Replace autoloader accessors with Rails.autoloaders.{main,once}Xavier Noria2019-02-143-18/+33
| | | | | | | | | | | | | | | | Rails.autoloader and Rails.once_autoloader was just tentative API good enough for a first patch. Rails.autoloader is singular and does not convey in its name that there is another autoloader. That might be confusing, for example if you set a logger and miss traces. On the other hand, the name `once_autoloader` is very close to being horrible. Rails.autoloaders.main and Rails.autoloaders.once read better for my taste, and have a nice symmetry. Also, both "main" and "once" are four letters long, short and same length. They are tagged as "rails.main" and "rails.once", respectively. References #35235.

| * Fix the `config_for` to always return a NonSymbolAccessDeprecatedHash:Edouard CHIN2019-02-141-4/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - If you have hashes inside array, the hashes were getting initialized as regular HWIA wereas we want them to be NonSymbolAccessDeprecatedHash in order to trigger a deprecation warning when keys are accessed with string. This patch fixes that by overwriting the `[]=` to to the same as what HWIA does (with the difference that we don't call `convert_key` to not trigger a deprecation when setting value). I also took the liberty to extract `hash.nested_under_indifferent_access`, into a separate method to allow subclasses to return whatever they want. Inheriting HWIA is not common, but I think it's useful for cases like this one where we want to preprocess reading and writing values in the hash (for deprecation purposes or other reasons).

|\ | | | | Allow deprecated non-symbol access to nested `config_for` hashes
| * Allow deprecated non-symbol access to nested `config_for` hashesUfuk Kayserilioglu2019-02-111-2/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A change to `Rails::Application.config_for` in https://github.com/rails/rails/pull/33815 and https://github.com/rails/rails/pull/33882 has altered the behaviour of the returned object in a breaking manner. Before that change, nested hashes returned from `config_for` could be accessed using non-symbol keys. After the change, all keys are recursively symbolized so non-symbol access fails to read the expected values. This is a breaking change for any app that might be relying on the nested hashes returned from `config_for` calls, and thus should be deprecated before being removed from the codebase. This commit introduces a temporary `NonSymbolAccessDeprecatedHash` class that recursively wraps any nested hashes inside the `OrderedOptions` object returned from `config_for` and issues a deprecation notice when a non-symbol based access is performed. This way, apps that are still relying on the ability to access these nested hashes using non-symbol keys will be able to observe the deprecation notices and have time to implement changes before non-symbol access is removed for good. A CHANGELOG entry is also added to note that non-symbol access to nested `config_for` hashes is deprecated.

* | Adds basic automatic database switching to RailsEileen Uchitelle2019-01-301-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following PR adds behavior to Rails to allow an application to automatically switch it's connection from the primary to the replica. A request will be sent to the replica if: * The request is a read request (`GET` or `HEAD`) * AND It's been 2 seconds since the last write to the database (because we don't want to send a user to a replica if the write hasn't made it to the replica yet) A request will be sent to the primary if: * It's not a GET/HEAD request (ie is a POST, PATCH, etc) * Has been less than 2 seconds since the last write to the database The implementation that decides when to switch reads (the 2 seconds) is "safe" to use in production but not recommended without adequate testing with your infrastructure. At GitHub in addition to the a 5 second delay we have a curcuit breaker that checks the replication delay and will send the query to a replica before the 5 seconds has passed. This is specific to our application and therefore not something Rails should be doing for you. You'll need to test and implement more robust handling of when to switch based on your infrastructure. The auto switcher in Rails is meant to be a basic implementation / API that acts as a guide for how to implement autoswitching. The impementation here is meant to be strict enough that you know how to implement your own resolver and operations classes but flexible enough that we're not telling you how to do it. The middleware is not included automatically and can be installed in your application with the classes you want to use for the resolver and operations passed in. If you don't pass any classes into the middleware the Rails default Resolver and Session classes will be used. The Resolver decides what parameters define when to switch, Operations sets timestamps for the Resolver to read from. For example you may want to use cookies instead of a session so you'd implement a Resolver::Cookies class and pass that into the middleware via configuration options. ``` config.active_record.database_selector = { delay: 2.seconds } config.active_record.database_resolver = MyResolver config.active_record.database_operations = MyResolver::MyCookies ``` Your classes can inherit from the existing classes and reimplment the methods (or implement more methods) that you need to do the switching. You only need to implement methods that you want to change. For example if you wanted to set the session token for the last read from a replica you would reimplement the `read_from_replica` method in your resolver class and implement a method that updates a new timestamp in your operations class.
