| * | Simplify Postgres query for column_definitions()Jordan Lewis2017-01-301-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | column_definitions() needs to fetch the collation for every column, if present. Previously, it did so using a correlated subquery - a subquery that references results from the outer scope. This patch updates the query to remove the subquery in favor of a simpler and more efficient JOIN clause. Running the two queries through EXPLAIN against Postgres additionally shows that the original form with a correlated subquery requires a Nested Loop Left Join, while the new form with a simple JOIN can use a more efficient Merge Left Join.

| | | | | | | | | | `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.

* | Don't guard against `touch: []`.Kasper Timm Hansen2017-01-151-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. [ Eugene Kenny & Kasper Timm Hansen ]

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `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.
* | | Fix pool_from_any_process to use most recent speceileencodes2017-01-131-1/+1
|/ / | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

|/ / / | | | | | | | | | | | | | | | 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.
