* Ensure test threads share a DB connectioneileencodes2017-02-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | This ensures multiple threads inside a transactional test to see consistent database state. When a system test starts Puma spins up one thread and Capybara spins up another thread. Because of this when tests are run the database cannot see what was inserted into the database on teardown. This is because there are two threads using two different connections. This change uses the statement cache to lock the threads to using a single connection ID instead of each not being able to see each other. This code only runs in the fixture setup and teardown so it does not affect real production databases. When a transaction is opened we set `lock_thread` to `Thread.current` so we can keep track of which connection the thread is using. When we rollback the transaction we unlock the thread and then there will be no left-over data in the database because the transaction will roll back the correct connections. [ Eileen M. Uchitelle, Matthew Draper ]

| | | | | | | | | | Unlike `one?` and `none?`, `empty?` has interactions with methods outside of enumerable. It also doesn't fit in the same vein. `Topic.any?` makes sense. `Topic.empty?` does not, as `Topic` is not a container. Fixes #24808 Close #24812

|/ | | | | | | | | | | | | This reverts commit f6db31ec16e42ee7713029f7120f0b011d1ddc6c. Reason: Scope names can very easily conflict, particularly when sharing Concerns within the team, or using multiple gems that extend AR models. It is true that Ruby has the ability to detect this with the -w option, but the reality is that we are depending on too many gems that do not care about Ruby warnings, therefore it might not be a realistic solution to turn this switch on in our real-world apps.
* Skip the STI condition when evaluating a default scopeMatthew Draper2016-01-121-0/+14
| | | | | | | | | | | | | Given a default_scope on a parent of the current class, where that parent is not the base class, the parent's STI condition would become attached to the evaluated default scope, and then override the child's own STI condition. Instead, we can treat the STI condition as though it is a default scope, and skip it in this situation: the scope will be merged into the base relation, which already contains the correct STI condition. Fixes #22426.
* Active scopes apply to child classes, though not parents/siblingsMatthew Draper2016-01-121-3/+17
| | | | | | | While the commit message (and changelog example) in 5e0b555b453ea2ca36986c111512627d806101e7 talked about sibling classes, the added test had a child ignore its parent's scoping, which seems less reasonable.

* Error message testing fixFranky W2015-02-201-2/+4
| | | | | | | | | The testing of error messages have been implemented wrongly a few times. This is an attempt to fix it. For example, some of these test should have failed with the new code. The reason they are not failling with the new string is the fact they were not being tested beforehand.
* `current_scope` shouldn't pollute sibling STI classesSean Griffin2015-02-111-0/+6
| | | | | | | | | | | | It looks like the only reason `current_scope` was thread local on `base_class` instead of `self` is to ensure that when we call a named scope created with a proc on the parent class, it correctly uses the default scope of the subclass. The reason this wasn't happening was because the proc captured `self` as the parent class, and we're not actually defining a real method. Using `instance_exec` fixes the problem. Fixes #18806
* `WhereClause#predicates` does not need to be publicSean Griffin2015-01-273-7/+7
| | | | | | | | | | | The only place it was accessed was in tests. Many of them have another way that they can test their behavior, that doesn't involve reaching into internals as far as they did. `AssociationScopeTest` is testing a situation where the where clause would have one bind param per predicate, so it can just ignore the predicates entirely. The where chain test was primarly duplicating the logic tested on `WhereClause` directly, so I instead just make sure it calls the appropriate method which is fully tested in isolation.

* Remove all cases of manuallly wrapping `Arel::Nodes::Quoted`Sean Griffin2014-12-291-4/+2
| | | | | | | | | | This is no longer required now that we are injecting a type caster object into the Arel table, with the exception of uniqueness validations. Since it calls `ConnectionAdapter#type_cast`, the value has already been cast for the database. We don't want Arel to attempt to cast it further, so we need to continue wrapping it in a quoted node. This can potentially go away when this validator is refactored to make better use of `where` or the predicate builder.
* Inform Arel that we don't need to cast a value in testsSean Griffin2014-12-261-2/+4
| | | | | | | Part of the larger refactoring to remove type casting from Arel. We can inform it that we already have the right type by wrapping the value in an `Arel::Nodes::Quoted`. This commit can be reverted when we have removed type casting from Arel in Rail 5.1
