Add test for update_counters with empty touch array

This is a regression test for a fix included in
https://github.com/rails/rails/commit/bad9bfbea6d6af9dc28583e08a49492668087393.
Without that change, this test would fail with:
ActiveRecord::StatementInvalid: SQLite3::SQLException: near "WHERE": syntax error: UPDATE "topics" SET "replies_count" = COALESCE("replies_count", 0) - 1, WHERE "topics"."id" = ?

`timestamp_attributes_for_updates_in_model` returns an empty
array when a model has no `updated_at` or `updated_on`.
So my previously thought uncommon case is a lot more likely
now.
This reverts commit a0a1ede8c2eb6436571eae8778033162d1f9dcc3.

Closes #27683.
Seeing a code sample that leads to what we're guarding against:
```ruby
Topic.update_counters(1, replies_count: 1, touch: [])
```
It doesn't look like a case people would ever intentionally end
up with. Thus we're better off sparing the conditional.
Note: it could happen if a method returns an empty array
that's then passed to `update_counters` and its touchy friends.
But `[].presence` can fix that once people see their query blow
up.

Add the touch option to ActiveRecord#increment! and decrement!
|
| | | | | |
| | | | | |
| | | | | |
| | | | | |
| | | | | | |
Supports the `touch` option from update_counters.
The default behavior is not to update timestamp columns.

`scope_for_create`
`type_condition` should be overwritten by `create_with_value`. So `type`
in `create_with_value` should be a string because `where_values_hash`
keys are converted to string.
Fixes #27600.

If a process is forked more than once, the pool was grabbing the oldest
spec, not the most recent spec. This wasn't noticed before because most
folks are lilely forking the process only once.
If you're forking the process multiple times however the wrong spec name
will be returned and an incorrect connection will be used for the
process.
This fixes the issue by reversing the list of spec names so we can grab
the most recent spec rather than the oldest spec.

because Struct.new returns a Class, we just can give it a name and use it directly without inheriting from it

(I personally prefer writing one string in one line no matter how long it is, though)

activerecord/test: Fix Mysql2ConnectionTest#test_execute_after_disconnect

| | | | | | |
| | | | | | | |
Mysql2ConnectionTest#test_execute_after_disconnect was originally added to
catch a NoMethodError occuring in execute when the Mysql2Adapter has a nil
`@connection`. Pull request #26869 removed the error message check in that
test because the error message changed in the mysql2 gem, which caused the
test to fail. Now the test wouldn't catch the original bug since the
NoMethodError would get turned into a ActiveRecord::StatementInvalid
exception.
Check the cause of the StatementInvalid exception to make sure it is of the
correct type.

Deprecate reflection class name to accept a class

| | | | | |
| | | | | |
| | | | | |
| | | | | |
| | | | | |
| | | | | |
| | | | | |
| | | | | | |
The idea of `class_name` as an option of reflection is that passing a
string would allow us to lazy autoload the class.
Using `belongs_to :client, class_name: Customer` is eagerloading models more than necessary
and creating possible circular dependencies.

Update increment! documentation [ci skip]

The `increment!` and `decrement!` methods were recently reimplemented to
make them safe to call from multiple connections concurrently. This
changed their behaviour in a few ways.
Previously they used `update_attribute`, which calls the attribute
setter method, runs callbacks, and touches the record. Now they behave
more like `update_column`, writing the update to the database directly
and bypassing all of those steps.

With the `singularize` call that is being done in that method when there
is multiple nestings of associations (JOIN calling a JOIN) and the
`stringify_keys!` is only called once here:
https://github.com/rails/rails/blob/21e5fd4/activerecord/lib/active_record/relation/where_clause_factory.rb#L16

In Rails 4.2 calling `ActiveRecord::Migrator.migrate` would return an array of results. Without realizing that this return type was expected I accidentally introduced a change in https://github.com/rails/rails/commit/4d60e93174a3d6d90b1a06fc7515cb5cd749a6f3
This PR preserves the previous behavior and adds a test on the return type. This will need a backport to 5.0 branch.
