* | activerecord/test: Fix Mysql2ConnectionTest#test_execute_after_disconnectDylan Thacker-Smith2017-01-091-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Mysql2ConnectionTest#test_execute_after_disconnect was originally added to catch a NoMethodError occuring in execute when the Mysql2Adapter has a nil `@connection`. Pull request #26869 removed the error message check in that test because the error message changed in the mysql2 gem, which caused the test to fail. Now the test wouldn't catch the original bug since the NoMethodError would get turned into a ActiveRecord::StatementInvalid exception. Check the cause of the StatementInvalid exception to make sure it is of the correct type.
* | Deprecate reflection class name to accept a classKir Shatrov2017-01-093-3/+11
|/ | | | | | | | The idea of `class_name` as an option of reflection is that passing a string would allow us to lazy autoload the class. Using `belongs_to :client, class_name: Customer` is eagerloading models more than necessary and creating possible circular dependencies.

Without realizing that this return type was expected I accidentally introduced a change in https://github.com/rails/rails/commit/4d60e93174a3d6d90b1a06fc7515cb5cd749a6f3 This PR preserves the previous behavior and adds a test on the return type. This will need a backport to 5.0 branch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Per the regression commit below, the commit changes the behavior of `#changed?`to consult the `#changed_in_place?` method on `Type::Value` classes. Per this change, `PostgreSQL::OID::Hstore` needs to override this method in order to compare the deserialized forms of the two arguments. In Ruby, two hashes are considered equal even if their key order is different. This commit helps to bring that behavior to `Hstore` values.

This was in line with our general attempt to reduce the number of adapter specific type subclasses. However, on PG, the array type performs all serialization, including database encoding in its serialize method. This means that we have converted the value into a string before reaching the database, so no adapter specific logic can be applied (and this also means that timestamp arrays were using the default `.to_s` method on the given object, which likely meant timestamps were being ignored in certain cases as well) Ultimately I want to do a more in depth refactoring which separates database serializer objects from the active model type objects, to give us a less awkward API for introducing the attributes API onto Active Model. However, in the short term, we follow the solution we've applied elsewhere for this. Move behavior off of the type and into the adapter, and use a data object to allow the type to communicate information up the stack. Fixes #27514.

We realized that the cause of it is the slow STI model instantiation. Problematic method appears to be `ActiveRecord::Base.compute_type`, which is used to find the right class for STI model on every instantiation. It builds an array of candidate types and then iterates through it calling `safe_constantize` on every type until it finds appropriate constant. So if desired type isn't the first element in this array there will be at least one unsuccessful call to `safe_constantize`, which is very expensive, since it's defined in terms of `begin; rescue; end`. This commit is an attempt to speed up `compute_type` method simply by caching results of previous calls. ```ruby class MyCompany::MyApp::Business::Accounts::Base < ApplicationRecord self.table_name = 'accounts' self.store_full_sti_class = false end class MyCompany::MyApp::Business::Accounts::Free < Base end class MyCompany::MyApp::Business::Accounts::Standard < Base # patch .compute_type there end puts '======================= .compute_type =======================' Benchmark.ips do |x| x.report("original method") do MyCompany::MyApp::Business::Accounts::Free.send :compute_type, 'Free' end x.report("with types cached") do MyCompany::MyApp::Business::Accounts::Standard.send :compute_type, 'Standard' end x.compare! end ``` ``` ======================= .compute_type ======================= with types cached: 1529019.4 i/s original method: 2850.2 i/s - 536.46x slower ``` ```ruby 5_000.times do |i| MyCompany::MyApp::Business::Accounts::Standard.create!(name: "standard_#{i}") end 5_000.times do |i| MyCompany::MyApp::Business::Accounts::Free.create!(name: "free_#{i}") end puts '====================== .limit(100).to_a =======================' Benchmark.ips do |x| x.report("without .compute_type patch") do MyCompany::MyApp::Business::Accounts::Free.limit(100).to_a end x.report("with .compute_type patch") do MyCompany::MyApp::Business::Accounts::Standard.limit(100).to_a end x.compare! end ``` ``` ====================== .limit(100).to_a ======================= with .compute_type patch: 360.5 i/s without .compute_type patch: 24.7 i/s - 14.59x slower ```
