With the introduction of the middleware Rails begins to assume it's `writing` and `reading` and there's no room for other roles. At GitHub we've been using this method for a long time so we have a ton of legacy code that uses different handler names `default` and `readonly`. We could rename all our code but I think this is better for a few reasons: - Legacy apps that have been using multiple databases for a long time can have an eaiser time switching. - If we later find this to cause more issues than it's worth we can easily deprecate. - We won't force old apps to rewrite the resolver middleware just to use a different handler. Adding the writing_role/reading_role required that I move the code that creates the first handler for writing to the railtie. If I didn't move this the core class would assign the handler before I was able to assign a new one in my configuration and I'd end up with 3 handlers instead of 2.

Since it's relatively common to create foreign keys with custom column names or primary keys, it seems like this should help quite a few people. [ci skip]

However I can see us supporting other options in the future. This PR refactors the options to get passed into the resolver so whether you're using middleware or using the config options you can pass options to the resolver. This will also make it easy to add new options in the future.

Idealy a test should behave the same wether or not transactional fixtures are enabled. However since transactions have been made lazy, the fixture transaction started leaking into tests case. e.g. consider the following (oversimplified) test: ```ruby class SQLSubscriber attr_accessor :sql def initialize @sql = [] end def call(*, event) sql << event[:sql] end end subscriber = SQLSubscriber.new ActiveSupport::Notifications.subscribe("sql.active_record", subscriber) User.connection.execute('SELECT 1', 'Generic name') assert_equal ['SELECT 1'], subscriber.sql ``` On Rails 6 it starts to break because the `sql` array will be `['BEGIN', 'SELECT 1']`. Several things are wrong here: - That transaction is not generated by the tested code, so it shouldn't be visible. - The transaction is not even closed yet, which again doesn't reflect the reality.

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.
* / / / / / / / / Fix case when we want a UrlConfig but the URL is nilEileen Uchitelle2019-01-302-5/+12

This can happen when you're relying on a `DATABASE_URL` in the env and that is not set in the environment. ``` production: <<: *default url: ENV['DATABASE_URL'] ``` This PR fixes that case by checking if there is a `url` key in the config instead of checking if the `url` is not nil in the config. In addition to changing the conditional we then need to build a url hash to merge with the original hash in the `UrlConfig` object. Fixes #35091

It is sometimes too short when people want to use a text column, so they sometimes change the text size to mediumtext (16 MiB) or longtext (4 GiB) by giving the `limit` option. Unlike MySQL, PostgreSQL doesn't allow the `limit` option for a text column (raises ERROR: type modifier is not allowed for type "text"). So `limit: 4294967295` (longtext) couldn't be used in Action Text. I've allowed changing text and blob size without giving the `limit` option, it prevents that migration failure on PostgreSQL.

In my test application this caused the application to thrown an error if I tried to send the first request to the replica before the replica was connected. This wouldn't be an issue in production because the application is preloaded. In order to fix this I decided to leave the original error message and delete the new error message. I updated the original error message to include the `role` to make it a bit clearer that the connection isn't established for that particular role. The error now reads: ``` No connection pool with 'primary' found for the 'reading' role. ``` A single database application will continue uisng the original error message: ``` No connection pool with 'primary' found. ```

So `StatementCache#execute` is the only place to raise the exception for finder queries. `StatementCache` is used for simple equality queries in the codebase. This means that if `StatementCache#execute` raises `RangeError`, the result could always be regarded as empty. So `StatementCache#execute` just return nil in that range error case, and treat that as empty in the caller side, then we can avoid catching the exception in much places.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently several queries cannot return correct result due to incorrect `RangeError` handling. First example: ```ruby assert_equal true, Topic.where(id: [1, 9223372036854775808]).exists? assert_equal true, Topic.where.not(id: 9223372036854775808).exists? ``` The first example is obviously to be true, but currently it returns false. Second example: ```ruby assert_equal topics(:first), Topic.where(id: 1..9223372036854775808).find(1) ``` The second example also should return the object, but currently it raises `RecordNotFound`. It can be seen from the examples, the queries including large number assuming empty result is not always correct. Therefore, This change handles `RangeError` to generate executable SQL instead of raising `RangeError` to users to always return correct result. By this change, it is no longer raised `RangeError` to users.

Previously if you had an application with a missing configuation and multiple databases the error message would look like this: ``` 'doesnexist' database is not configured. Available: development, development, test, test, production, production (ActiveRecord::AdapterNotSpecified) ``` That's not very descriptive since it duplicates the environments (because there are multiple databases per environment for this application). To fix this I've constructed a bit more readable error message which now reads like this if you have a multi db app: ``` The `doesntexist` database is not configured for the `production` environment. (ActiveRecord::AdapterNotSpecified) Available databases configurations are: development: primary, primary_readonly test: primary, primary_readonly production: primary, primary_readonly ``` And like this if you have a single db app: ``` The `doesntexist` database is not configured for the `production` environment. (ActiveRecord::AdapterNotSpecified) Available databases configurations are: development test ``` This makes the error message more readable and presents the user all available options for the database connections.
