Reason: Marking as loaded without actual loading is too greedy optimization. See more context #35239. Closes #35239. [Edouard CHIN & Ryuta Kamizono]

| * Fix DatabaseSelector test that fails sometimeseileencodes2019-02-121-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On CI we've seen a few test failures when the DatabaseSelectorTest runs before the ConnectionHandlersMultiDbTest. This is because it's creating 2 handlers but not properly tearing them down. Example failure: ``` Failure: ActiveRecord::ConnectionAdapters::ConnectionHandlersMultiDbTest#test_connects_to_with_single_configuration [/rails/activerecord/test/cases/connection_adapters/connection_handlers_multi_db_test.rb:241]: Expected: 1 Actual: 2 ```

| | | | | | | | | | | | | | | | | | | | | | | | I implemented Foreign key create in `create_table` for SQLite3 at #24743. This follows #24743 to implement `add_foreign_key` and `remove_foreign_key`. Unfortunately SQLite3 has one limitation that `PRAGMA foreign_key_list(table-name)` doesn't have constraint name. So we couldn't implement find/remove foreign key by name for now. Fixes #35207. Closes #31343.

| | | | | | | | | | | | | | | | | | | | | | `Association#target=` invokes `loaded!`, so we no longer need to call the `loaded!` explicitly. Since Preloader is private API, we don't guarantee that it behaves like older version as long as using Preloader directly. But this refactoring fortunately also fix the Preloader compatibility issue #35195. Closes #35195.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The `distinct` affects (reduces) rows of the result, so it is important part when both `distinct` and `offset` are given. Replacing SELECT clause to `1 AS one` and removing `distinct` and `order` is just optimization for the `exists?`, we should not apply the optimization for that case. Fixes #35191.

But the effect of `scoping` is class global, it was caused undesired behavior that pollute all class level querying methods in initialization block and callbacks (`after_initialize`, `before_validation`, `before_save`, etc), which are user provided code. To avoid the leaking scope issue, restore the original current scope before initialization block and callbacks are invoked. Fixes #9894. Fixes #17577. Closes #31526.

The variable name is based on the "virtual path" used for looking up the template. The same virtual path information lives on the template, so we can just ask the cached template object for the variable. This benchmark takes a couple files, so I'll cat them below: ``` [aaron@TC ~/g/r/actionview (speed-up-partials)]$ cat render_benchmark.rb require "benchmark/ips" require "action_view" require "action_pack" require "action_controller" class TestController < ActionController::Base end TestController.view_paths = [File.expand_path("test/benchmarks")] controller_view = TestController.new.view_context result = Benchmark.ips do |x| x.report("render") do controller_view.render("many_partials") end end [aaron@TC ~/g/r/actionview (speed-up-partials)]$ cat test/benchmarks/test/_many_partials.html.erb Looping: <ul> <% 100.times do |i| %> <%= render partial: "list_item", locals: { i: i } %> <% end %> </ul> [aaron@TC ~/g/r/actionview (speed-up-partials)]$ cat test/benchmarks/test/_list_item.html.erb <li>Number: <%= i %></li> ``` Benchmark results (master): ``` [aaron@TC ~/g/r/actionview (master)]$ be ruby render_benchmark.rb Warming up -------------------------------------- render 41.000 i/100ms Calculating ------------------------------------- render 424.269 (± 3.5%) i/s - 2.132k in 5.031455s ``` Benchmark results (this branch): ``` [aaron@TC ~/g/r/actionview (speed-up-partials)]$ be ruby render_benchmark.rb Warming up -------------------------------------- render 50.000 i/100ms Calculating ------------------------------------- render 521.862 (± 3.8%) i/s - 2.650k in 5.085885s ```

It was needed to restore the source scope in named scopes, but it was caused undesired behavior that pollute all class level querying methods. Example: ```ruby class Topic < ActiveRecord::Base scope :toplevel, -> { where(parent_id: nil) } scope :children, -> { where.not(parent_id: nil) } scope :has_children, -> { where(id: Topic.children.select(:parent_id)) } end # Works as expected. Topic.toplevel.where(id: Topic.children.select(:parent_id)) # Doesn't work due to leaking `toplevel` to `Topic.children`. Topic.toplevel.has_children ``` Since #29301, the receiver in named scopes has changed from the model class to the chaining source scope, so the polluting class level querying methods is no longer required for that purpose. Fixes #14003.
