* Add Relation#annotate for SQL commentingMatt Yoho2019-03-214-4/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch has two main portions: 1. Add SQL comment support to Arel via Arel::Nodes::Comment. 2. Implement a Relation#annotate method on top of that. == Adding SQL comment support Adds a new Arel::Nodes::Comment node that represents an optional SQL comment and teachers the relevant visitors how to handle it. Comment nodes may be added to the basic CRUD statement nodes and set through any of the four (Select|Insert|Update|Delete)Manager objects. For example: manager = Arel::UpdateManager.new manager.table table manager.comment("annotation") manager.to_sql # UPDATE "users" /* annotation */ This new node type will be used by ActiveRecord::Relation to enable query annotation via SQL comments. == Implementing the Relation#annotate method Implements `ActiveRecord::Relation#annotate`, which accepts a comment string that will be appeneded to any queries generated by the relation. Some examples: relation = Post.where(id: 123).annotate("metadata string") relation.first # SELECT "posts".* FROM "posts" WHERE "posts"."id" = 123 # LIMIT 1 /* metadata string */ class Tag < ActiveRecord::Base scope :foo_annotated, -> { annotate("foo") } end Tag.foo_annotated.annotate("bar").first # SELECT "tags".* FROM "tags" LIMIT 1 /* foo */ /* bar */ Also wires up the plumbing so this works with `#update_all` and `#delete_all` as well. This feature is useful for instrumentation and general analysis of queries generated at runtime.

* | Bulk Insert: Reuse indexes for unique_byKasper Timm Hansen2019-03-202-61/+55
|/ | | | | | | | | | | I found `:unique_by` with `:columns` and `:where` inside it tough to grasp. The documentation only mentioned indexes and partial indexes. So why duplicate a model's indexes in an insert_all/upsert_all call when we can just look it up? This has the added benefit of raising if no index is found, such that people can't insert thousands of records without relying on an index of some form.

OTOH, GeneratedAssociatedMethods is assigned to a constant under the model namespace. This is inconsistent and looks strange in the list of ancestors. There is no particular reason *not* to assign a constant for this (very important) module under the model namespace, so that's what this commit does. Previous to this change, ancestors for an AR class looked like this: ``` => [User (call 'User.connection' to establish a connection), User::GeneratedAssociationMethods, #<ActiveRecord::AttributeMethods::GeneratedAttributeMethods:0x000055ace0f05b08>, ApplicationRecord(abstract), ApplicationRecord::GeneratedAssociationMethods, #<ActiveRecord::AttributeMethods::GeneratedAttributeMethods:0x000055ace093c460>, ActiveRecord::Base, ... ``` With this change, they look like this: ``` => [User (call 'User.connection' to establish a connection), User::GeneratedAssociationMethods, User::GeneratedAttributeMethods, ApplicationRecord(abstract), ApplicationRecord::GeneratedAssociationMethods, ApplicationRecord::GeneratedAttributeMethods, ActiveRecord::Base, ... ``` The previously named `GeneratedAttributeMethods` module builder class is renamed `GeneratedAttributeMethodsBuilder` to emphasize that this is not a module but a class.

We'd see the following error: ``` lib/active_record/database_configurations.rb:72:in `block in find_db_config': undefined method `env_name' for [nil]:Array (NoMethodError) ``` The problem here is that Rails does correctly identify this as not a real configuration but returns `[nil]` along with the others. We need to make sure to flatten the array and remove all the `nil`'s before returning the `configurations` objects. Fixes #35646

Example: ```ruby class Job < ApplicationRecord default_scope { optimizer_hints("MAX_EXECUTION_TIME(50000) NO_INDEX_MERGE(jobs)") } end ``` Optimizer Hints is supported not only for MySQL but also for most databases (PostgreSQL on RDS, Oracle, SQL Server, etc), it is really helpful to turn heavy queries for large scale applications.

| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Details in https://github.com/rails/rails/issues/35519 In short, MySQL and Sqlite3 allow a record to be both inserted _and_ replaced in the same operation. Postgres (and the SQL-2003 rules for MERGE) do not. Postgres's rationale seems to be that the operation would be nondeterministic. I think it's OK for Rails users to have a different experience with this feature depending on their database; but I think you should be able to follow the examples in the docs on any database.
