|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit eec3e28a1abf75676dcee58308ee5721bb53c325, reversing changes made to 5588fb4802328a2183f4a55c36d6703ee435f85c. Reason: Marking as loaded without actual loading is too greedy optimization. See more context #35239. Closes #35239. [Edouard CHIN & Ryuta Kamizono]

| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently custom attributes are always qualified by the table name in the generated SQL wrongly even if the table doesn't have the named column, it would cause an invalid SQL error. Custom attributes should only be qualified if the table has the same named column.

* | | SQLite3: Implement `add_foreign_key` and `remove_foreign_key`Ryuta Kamizono2019-02-115-6/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | | Refactor to just use `Association#target=` in `associate_records_to_owner`Ryuta Kamizono2019-02-091-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `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.

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 ```

* | | Chaining named scope is no longer leaking to class level querying methodsRyuta Kamizono2019-02-064-8/+9
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Active Record uses `scoping` to delegate to named scopes from relations for propagating the chaining source scope. 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.

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.

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.
