| * Active Record supports MySQL >= 5.1.10Ryuta Kamizono2016-12-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | Follow up to #25307 and #23458. Related with #27422. We are using `information_schema.referential_constraints` since #25307. The table was introduced in MySQL 5.1.10. MySQL 5.0 is too old. It is enough to support >= 5.1.10 at least. MySQL 5.0 GA was released in Dec 2005 and already EOL in Dec 2011. MySQL 5.1 GA was released in Dec 2008 and already EOL in Dec 2013.

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 ```

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently does not work the following example in the doc: ```ruby # For the Posts with id of 10 and 15, increment the comment_count by 1 # and update the updated_at value for each counter. Post.update_counters [10, 15], comment_count: 1, touch: true # Executes the following SQL: # UPDATE posts # SET comment_count = COALESCE(comment_count, 0) + 1, # `updated_at` = '2016-10-13T09:59:23-05:00' # WHERE id IN (10, 15) ```

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Today `rake db:schema:cache:dump` only supports dumping cache for a single connection (`ActiveRecord::Base.connection`). This doesn't work for apps with multiple databases. This PR makes `DatabaseTasks` to provide an API for dumping schema cache for any connection.

| | | | | | | | | | | | | | | | | | | | `touch_updates` calls `Time.now` via `current_time_from_proper_timezone` so it is better to not invoke `touch_updates` if it is unnecessary.

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. Elaborate and show examples. Closes #26995. [ Jarred Trost & Kasper Timm Hansen ]

This allocates extra strings. To avoid extra allocation, change the definitions from symbol to string. ```ruby pp ObjectSpace::AllocationTracer.trace { 1_000.times { |i| Post.create! } } ``` Before: ``` ["~/rails/activerecord/lib/active_record/timestamp.rb", 121]=>[1002, 0, 750, 0, 1, 18528], ["~/rails/activerecord/lib/active_record/timestamp.rb", 105]=>[1002, 0, 750, 0, 1, 7720], ["~/rails/activerecord/lib/active_record/timestamp.rb", 101]=>[1002, 0, 750, 0, 1, 7720], ["~/rails/activerecord/lib/active_record/timestamp.rb", 109]=>[1002, 0, 750, 0, 1, 13896], ["~/rails/activerecord/lib/active_record/timestamp.rb", 61]=>[4008, 0, 3000, 0, 1, 30880], ``` After: ``` ["~/rails/activerecord/lib/active_record/timestamp.rb", 120]=>[1000, 0, 756, 0, 1, 17184], ["~/rails/activerecord/lib/active_record/timestamp.rb", 104]=>[1000, 0, 756, 0, 1, 7160], ["~/rails/activerecord/lib/active_record/timestamp.rb", 100]=>[1000, 0, 756, 0, 1, 7160], ["~/rails/activerecord/lib/active_record/timestamp.rb", 108]=>[1000, 0, 756, 0, 1, 12888], ```
