`#exec_stmt` is private method and only called in `#exec_query`. it means `binds` is provided always. No need `binds.empty?` checking.

* When tried to use `Company#accounts` test/models/company.rb I got: ``` ActiveRecord::StatementInvalid: SQLite3::SQLException: no such column: accounts.company_id: SELECT COUNT(*) AS count_all, "companies"."firm_id" AS companies_firm_id FROM "companies" INNER JOIN "accounts" ON "accounts"."company_id" = "companies"."id" GROUP BY "companies"."firm_id" ``` * The refactor on Calculations class was just to simplify the code

Closes #21922 Let `Book(id, author_id)`, `Photo(id, book_id, author_id)` and `Author(id)` Running `Book.group(:author_id).joins(:photos).count` will produce: * Rails 4.2 - conflicts `author_id` in both projection and group by: ```sql SELECT COUNT(*) AS count_all, author_id AS author_id FROM "books" INNER JOIN "photos" ON "photos"."book_id" = "books"."id" GROUP BY author_id ``` * Master (9d02a25d) - conflicts `author_id` only in projection: ```sql SELECT COUNT(*) AS count_all, author_id AS author_id FROM "books" INNER JOIN "photos" ON "photos"."book_id" = "books"."id" GROUP BY "books"."author_id" ``` * With this fix: ```sql SELECT COUNT(*) AS count_all, "books"."author_id" AS books_author_id FROM "books" INNER JOIN "photos" ON "photos"."book_id" = "books"."id" GROUP BY "books"."author_id" ```

This issue was resolved by #21687 already. But re-add args by #18856. `#tables` extra args was only using by `#table_exists?`. This is for internal API. This commit will remove these extra args again.

The getter is doing nothing more than returning the ivar, so it can be extracted to an attr_reader.

[ci skip] It's been a source of confusion that the lower-level `add_column` referenced the higher level `column` method for available options. `column` supports additional functionality like `index: true` that is not present on `add_column`. This patch moves common option documentation to `add_column` and only documents the additional options in `column`.

Prior to this commit, Rails makes no differentiation between whether a query uses bind parameters, and whether or not we cache that query as a prepared statement. This leads to the cache populating extremely fast in some cases, with the statements never being reused. In particular, the two problematic cases are `where(foo: [1, 2, 3])` and `where("foo = ?", 1)`. In both cases we'll end up quoting the values rather than using a bind param, causing a cache entry for every value ever used in that query. It was noted that we can probably eventually change `where("foo = ?", 1)` to use a bind param, which would resolve that case. Additionally, on PG we can change our generated query to be `WHERE foo = ANY($1)`, and pass an array for the bind param. I hope to accomplish both in the future. For SQLite and MySQL, we still end up preparing the statements anyway, we just don't cache it. The statement will be cleaned up after it is executed. On postgres, we skip the prepare step entirely, as an API is provided to execute with bind params without preparing the statement. I'm not 100% happy on the way this ended up being structured. I was hoping to use a decorator on the visitor, rather than mixing a module into the object, but the way Arel has it's visitor pattern set up makes it very difficult to extend without inheritance. I'd like to remove the duplication from the various places that are extending it, but that'll require a larger restructuring of that initialization logic. I'm going to take another look at the structure of it soon. This changes the signature of one of the adapter's internals, and will require downstream changes from third party adapters. I'm not too worried about this, as worst case they can simply add the parameter and always ignore it, and just keep their previous behavior. Fixes #21992.

With `unscope!` called last, it undoes `where` constraints of the same value when the `where` is chained after the `unscope`. This is what a `rewhere` does. This is undesirable behavior. The included tests demonstrate both the `unscope(...).where(...)` behavior as well as the direct use of `rewhere(...)`. This is in reference to #21955.

`WhereClauseFactory` handles all other branches based on argument types, so the code fits more naturally here, and it's just where the responsibility belongs.

[#20473]

由 Maarten Jacobs 提交于
The default timestamp used for AR is `updated_at` in nanoseconds! (:nsec) This causes issues on any machine that runs an OS that supports nanoseconds timestamps, i.e. not-OS X, where the cache_key of the record persisted in the database (milliseconds precision) is out-of-sync with the cache_key in the ruby VM. This commit adds: A test that shows the issue, it can be found in the separate file `cache_key_test.rb`, because - model couldn't be defined inline - transactional testing needed to be turned off to get it to pass the MySQL tests This seemed cleaner than putting it in an existing testcase file. It adds :usec as a dateformat that calculates datetime in microseconds It sets precision of cache_key to :usec instead of :nsec, as no db supports nsec precision on timestamps

This type adds an escape hatch to apps for which string duping causes unacceptable memory growth. The reason we are duping them is in order to detect mutation, which was a feature added to 4.2 in #15674. The string type was modified to support this behavior in #15788. Memory growth is really only a concern for string types, as it's the only mutable type where the act of coersion does not create a new object regardless (as we're usually returning an object of a different class). I do feel strongly that if we are going to support detecting mutation, we should do it universally for any type which is mutable. While it is less common and ideomatic to mutate strings than arrays or hashes, there shouldn't be rules or gotchas to understanding our behavior. However, I also appreciate that for apps which are using a lot of string columns, this would increase the number of allocations by a large factor. To ensure that we keep our contract, if you'd like to opt out of mutation detection on strings, you'll also be option out of mutation of those strings. I'm not completely married to the thought that strings coming out of this actually need to be frozen -- and I think the name is correct either way, as the purpose of this is to provide a string type which does not detect mutation. In the new implementation, I'm only overriding `cast_value`. I did not port over the duping in `serialize`. I cannot think of a reason we'd need to dup the string there, and the tests pass without it. Unfortunately that line was introduced at a time where I was not nearly as good about writing my commit messages, so I have no context as to why I added it. Thanks past Sean. You are a jerk.

When passing an instance of `ActiveRecord::Base` to `#update`, it would internally call `#find`, resulting in a misleading deprecation warning. This change gives this deprecated use of `#update` its own, meaningful warning.

Dirty checking keeps a hash where the keys are the column name and the value is a dup of the value from the database[1]. This hash is kept for every AR object, which means that we dup every column name for every AR object that does dirty checking. Freezing the column name prevents the column name from being duped and reduced overall string allocations. Here is a benchmark to demonstrate: ```ruby require 'active_record' class Topic < ActiveRecord::Base end 20.times do |i| Process.waitpid fork { ActiveRecord::Base.establish_connection adapter: 'sqlite3', database: ':memory:' ActiveRecord::Base.connection.instance_eval do create_table(:topics) do |t| t.string :title, limit: 250 t.string :author_name t.string :author_email_address t.string :parent_title t.string :type t.string :group i.times do |j| t.string :"aaa#{j}" end t.timestamps null: true end end ObjectSpace::AllocationTracer.setup(%i{type}) Topic.create title: "aaron" # heat cache result = ObjectSpace::AllocationTracer.trace do 10.times do |i| Topic.create title: "aaron #{i}" end end puts "#{Topic.columns.length},#{(result.find { |k,v| k.first == :T_STRING }.last.first / 10)}" } end ``` 1. https://github.com/rails/rails/blob/3ad381c3f8598d9920998c8949a96b5f62b280dd/activerecord/lib/active_record/attribute_set/builder.rb#L102

Currently `tinyblob` is dumped to `t.binary "tiny_blob", limit: 255`. But `t.binary ... limit: 255` is generating SQL to `varchar(255)`. It is incorrect. This commit fixes this problem.

The focus of this change is to make the API more accessible. References to method and classes should be linked to make it easy to navigate around. This patch makes exzessiv use of `rdoc-ref:` to provide more readable docs. This makes it possible to document `ActiveRecord::Base#save` even though the method is within a separate module `ActiveRecord::Persistence`. The goal here is to bring the API closer to the actual code that you would write. This commit only deals with Active Record. The other gems will be updated accordingly but in different commits. The pass through Active Record is not completely finished yet. A follow up commit will change the spots I haven't yet had the time to update. /cc @fxn
