* Correctly dump native timestamp types for MySQLRyuta Kamizono2017-02-231-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The native timestamp type in MySQL is different from datetime type. Internal representation of the timestamp type is UNIX time, This means that timestamp columns are affected by time zone. ``` > SET time_zone = '+00:00'; Query OK, 0 rows affected (0.00 sec) > INSERT INTO time_with_zone(ts,dt) VALUES (NOW(),NOW()); Query OK, 1 row affected (0.02 sec) > SELECT * FROM time_with_zone; +---------------------+---------------------+ | ts | dt | +---------------------+---------------------+ | 2016-02-07 22:11:44 | 2016-02-07 22:11:44 | +---------------------+---------------------+ 1 row in set (0.00 sec) > SET time_zone = '-08:00'; Query OK, 0 rows affected (0.00 sec) > SELECT * FROM time_with_zone; +---------------------+---------------------+ | ts | dt | +---------------------+---------------------+ | 2016-02-07 14:11:44 | 2016-02-07 22:11:44 | +---------------------+---------------------+ 1 row in set (0.00 sec) ```

* Deprecate `supports_primary_key?`Ryuta Kamizono2017-02-121-0/+5
| | | | | | | | | | | | `supports_primary_key?` was added to determine if `primary_key` is implemented in the adapter in f060221. But we already use `primary_key` without `supports_primary_key?` (207f266, 5f3cf42) and using `supports_primary_key?` has been removed in #1318. This means that `supports_primary_key?` is no longer used in the internal and Active Record doesn't work without `primary_key` is implemented (all adapters must implement `primary_key`). Closes #27977

* Fix collection_singular_ids= bugDaniel Colson2017-02-021-0/+6
| | | | | | | | | When the association's primary key is manually set as a symbol and called with an array of strings, CollectionAssociation#ids_writer fails to cast the ids to integers. This is because AssociationReflection#association_primary_key_type and ThroughReflection#association_primary_key_type return the incorrect type, since ModelSchema.type_for_attribute only accepts a string. The result is an ActiveRecord::RecordNotFound error.
* Virtual/generated column support for MySQL 5.7.5+ and MariaDB 5.2.0+Ryuta Kamizono2017-02-011-0/+19
| | | | | | | | | | | | | | | | | | | MySQL generated columns: https://dev.mysql.com/doc/refman/5.7/en/create-table-generated-columns.html MariaDB virtual columns: https://mariadb.com/kb/en/mariadb/virtual-computed-columns/ Declare virtual columns with `t.virtual name, type: …, as: "expression"`. Pass `stored: true` to persist the generated value (false by default). Example: create_table :generated_columns do |t| t.string :name t.virtual :upper_name, type: :string, as: "UPPER(name)" t.virtual :name_length, type: :integer, as: "LENGTH(name)", stored: true t.index :name_length # May be indexed, too! end Closes #22589

* Deprecate reflection class name to accept a classKir Shatrov2017-01-091-0/+5
| | | | | | | | 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.

* Compare deserialized values for `PostgreSQL::OID::Hstore` typesJon Moss2017-01-031-0/+7
| | | | | | | | | | | | | 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. Fixes regression introduced by 8e633e505880755e7e366ccec2210bbe2b5436e7 Fixes #27502

* Consistently apply adapter behavior when serializing arraysSean Griffin2017-01-031-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | In f1a0fa9 we moved backend specific timestamp behavior out of the type and into the adapter. 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.
* Cache results of computing model typeKonstantin Lazarev2017-01-031-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We faced a significant performance decrease when we started using STI without storing full namespaced class name in type column (because of PostgreSQL length limit for ENUM types). 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 ```
* Fix tests with counter cache touching and more.Kasper Timm Hansen2017-01-011-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Refactor to use `touch_updates` Ensures we only call `current_time_from_proper_timezone` from one place. * Clarify touch default in tests. Not interested in what happens when passed false but that nothing passed means no touching. * Backdate touched columns in tests. We can't be sure a test progresses through time, so our touching code may be working correctly but the test itself is brittle. Fix by backdating that's further in the past akin to what the timestamps tests do: https://github.com/rails/rails/blob/d753645d40e925973724e4c3a8617b654da90e41/activerecord/test/cases/timestamp_test.rb#L17 * Expand changelog entry.
