| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's say you have a nested transaction and both records are saved. Before the outer transaction closes, a rollback is performed. Previously the record in the outer transaction would get marked as not persisted but the inner transaction would get persisted. ```ruby Post.transaction do post_one.save # will get rolled back Post.transaction(requires_new: true) do post_two.save # incorrectly remains marked as persisted end raise ActiveRecord::Rollback end ``` To fix this the PR changes transaction handling to have the child transaction ask the parent how the records should be marked. When there are child transactions, it will always be a SavpointTransaction because the stack isn't empty. From there we pass the parent_transaction to the child SavepointTransaction where we add the children to the parent so the parent can mark the inner transaction as rolledback and thus mark the record as not persisted. `update_attributes_from_transaction_state` uses the `completed?` check to correctly mark all the transactions as rolledback and the inner record as not persisted. ```ruby Post.transaction do post_one.save # will get rolled back Post.transaction(requires_new: true) do post_two.save # with new behavior, correctly marked as not persisted on rollback end raise ActiveRecord::Rollback end ``` Fixes #29320
| * Deprecate and replace `set_state` methodeileencodes2017-07-011-6/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | `set_state` was directly setting the transaction state instance variable. It's better to set the state via specific methods (`rollback!` and `commit!` respectively. While undocumented and untested, it's possible someone is using `set_state` in their app or gem so I've added a deprecation notice to it. No where in the app do we use `nullify!` but I wanted to keep existing behavior while replacing the method with a better pattern.

* | | Avoid begin/rescue in fixture quotingKir Shatrov2017-06-201-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Scalar values like arrays and hashes can't be inserted directly into table. Previously, the way to determine if the value is scalar was to try quoting it. If `quote` raised with an error than the value has to be converted to YAML. This flow is not very obvious. Ideally we could have a `quotable?` method in the connection, but I think that we can avoid begin/rescue block by simply checking if the value is Array or Hash. https://github.com/rails/rails/commit/aa31d21f5f4fc4d679e74a60f9df9706da7de373

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | Another fix for #28780 based on discussions at #28789 - In PostgreSQL 10 each sequence does not know its `min_value`. A new system catalog `pg_sequence` shows it as `seqmin`. Refer https://github.com/postgres/postgres/commit/1753b1b027035029c2a2a1649065762fafbf63f3 - `setval` 3rd argument needs to set to `false` only when the table has no rows to avoid `nextval(<sequence_name>)` returns `2` where `1` is expected. - `min_value` is only necessary when the table has no rows. It used to be necessary since the 3rd argument of `setval` is always `false`.

| * | `rename_table` renames primary key index nameYaw Boakye2017-05-291-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Formerly, `rename_table` only renamed primary key index name if the column's data type was sequential (serial, etc in PostgreSQL). The problem with that is tables whose primary keys had other data types (e.g. UUID) maintained the old primary key name. So for example, if the `cats` table has a UUID primary key, and the table is renamed to `felines`, the primary key index will still be called `cats_pkey` instead of `felines_pkey`. This PR corrects it.

| | | | | | | | | | | | | | `supports_statement_cache?` was introduced in 3.1.0.beta1 (104d0b2) for bind parameter substitution, but it is no longer used in 3.1.0.rc1 (73ff679). Originally it should respect `prepared_statements` rather than `supports_statement_cache?` (fd39847). One more thing, named `supports_statement_cache?` is pretty misreading. We have `StatementCache` and `StatementPool`. However, `supports_statement_cache?` doesn't mean `StatementCache`, but `StatementPool` unlike its name. https://github.com/rails/rails/blob/v5.1.0/activerecord/lib/active_record/statement_cache.rb https://github.com/rails/rails/blob/v5.1.0/activerecord/lib/active_record/connection_adapters/statement_pool.rb
