* Bump the minimum version of PostgreSQL to 9.3Yasuo Honda2018-11-258-402/+382
| | | | | | | | | | | | | | | | | | | | https://www.postgresql.org/support/versioning/ - 9.1 EOLed on September 2016. - 9.2 EOLed on September 2017. 9.3 is also not supported since Nov 8, 2018. https://www.postgresql.org/about/news/1905/ I think it may be a little bit early to drop PostgreSQL 9.3 yet. * Deprecated `supports_ranges?` since no other databases support range data type * Add `supports_materialized_views?` to abstract adapter Materialized views itself is supported by other databases, other connection adapters may support them * Remove `with_manual_interventions` It was only necessary for PostgreSQL 9.1 or earlier * Drop CI against PostgreSQL 9.2

| * Fix query cache for multiple connectionsEileen Uchitelle2018-11-202-4/+27
| | | | | | | | | | | | | | | | | | | | Currently the query cache is only aware of one handler so once we added multiple databases switching on the handler we broke query cache for those reading connections. While #34054 is the proper fix, that fix is not straight forward and I want to make sure that the query cache isn't just broken for all other connections not in the main handler.
* | Make connection handler per thread instead of per fiberEileen Uchitelle2018-11-202-2/+39
|/ | | | | | | | | | | | | | | The connection handler was using the RuntimeRegistry which kind of implies it's a per thread registry. But it's actually per fiber. If you have an application that uses fibers and you're using multiple databases, when you switch the connection handler to swap connections new fibers running on the same thread used to get a different connection id. This PR changes the code to actually use a thread so that we get the same connection. Fixes https://github.com/rails/rails/issues/30047 [Eileen M. Uchitelle, Aaron Patterson, & Arthur Neeves]

E.g. post.people = [person, person] post.people.count # => 2 while post.people = [person] post.people = [person, person] post.people.count # => 1 This change adds a test to provoke the former incorrect behavior, and fixes it. Cause of the bug was the handling of record collections as sets, and using `-` (difference) and `&` (union) operations on them indiscriminately. This temporary conversion to sets would eliminate duplicates. The fix is to decorate record collections for these operations, and only for the `has_many :through` case. It is done by counting occurrences, and use the record together with the occurrence number as element, in order to make them work well in sets. Given a, b = *Person.all then the collection used for finding the difference or union of records would be internally changed from [a, b, a] to [[a, 1], [b, 1], [a, 2]] for these operations. So a first occurrence and a second occurrence would be distinguishable, which is all that is necessary for this task. Fixes #33942.

| |/ / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds support for the `ActiveRecord::ConnectionAdapters::PostgreSQLAdapter.create_unlogged_tables` setting, which turns `CREATE TABLE` SQL statements into `CREATE UNLOGGED TABLE` statements. This can improve PostgreSQL performance but at the cost of data durability, and thus it is highly recommended that you *DO NOT* enable this in a production environment.
* | | Remove ensure from with_transaction_returning_statusEugene Kenny2018-11-111-4/+0
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The test added in 12b0b26df7560ab5199ba830586864085441508f passes even without this code since 9b8c7796a9c2048208aa843ad3dc477dffa8bdee, as the call to `id` in `remember_transaction_record_state` now triggers a `sync_with_transaction_state` which discards the leftover state from the previous transaction. This issue had already been fixed for `save!`, `destroy` and `touch` in caae79a385ce112245262a17414bcd96bea013c2, but continued to affect `save` because the call to `rollback_active_record_state!` in that method would increment the transaction level before `add_to_transaction` could clear it, preventing the fix from working correctly. As `rollback_active_record_state!` was removed entirely in 48007d5390db47fc1223f57c8e7ab3ebb7c3a3d7, this code is no longer needed.

| | | | | | | | | | | | | | | | | | | | Related 34cc301f03aea2e579d6687a9ea9782afc1089a0. `QueryAttribute#value_for_database` calls only `type.serialize`, and `Decimal#serialize` is a no-op unlike other attribute types. Whether or not `serialize` will invoke `cast` is undefined in our test cases, but it actually does not work properly unless it does so for now.

* | Always add records to parent of nested transactionEugene Kenny2018-11-072-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a record with transactional callbacks is saved, it's attached to the current transaction so that the callbacks can be run when the transaction is committed. Records can also be added manually with `add_transaction_record`, even if they have no transactional callbacks. When a nested transaction is committed, its records are transferred to the parent transaction, as transactional callbacks should only be run when the outermost transaction is committed (the "real" transaction). However, this currently only happens when the record has transactional callbacks, and not when added manually with `add_transaction_record`. If a record is added to a nested transaction, we should always attach it to the parent transaction when the nested transaction is committed, regardless of whether it has any transactional callbacks.

* Fix inspect with non-primary key id attributeEugene Kenny2018-11-065-3/+26
| | | | | | | | | | | The `read_attribute` method always returns the primary key when asked to read the `id` attribute, even if the primary key isn't named `id`, and even if another attribute named `id` exists. For the `inspect`, `attribute_for_inspect` and `pretty_print` methods, this behaviour is undesirable, as they're used to examine the internal state of the record. By using `_read_attribute` instead, we'll get the real value of the `id` attribute.
