| | | | | | | | | | `merge! association.scope(nullify: false)` is expensive but most methods do not need the merge.

|\ \ | | | | | | Remove the top-level `HashWithIndifferentAccess` contant
| * | Deprecate the top-level `HashWithIndifferentAccess` contantRobin Dupret2017-02-191-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | This constant was kept for the sake of backward compatibility; it is still available under `ActiveSupport::HashWithIndifferentAccess`. Furthermore, since Ruby 2.5 (https://bugs.ruby-lang.org/issues/11547) won't support top level constant lookup, people would have to update their code anyway.

| | | | | | | | | | | | | | | | | | | | | | | | Oracle database itself does not have `bigint` SQL type, then it gets `ORA-00902: invalid datatype`. It can be addressed by using ActiveRecord `bigint` type because Oracle enhanced adapter recognizes ActiveRecord `bigint` type and transfer it to its equivalent SQL type `NUMBER(19)`.

| * | | Simplify and optimize Postgres query for primary_keys()Jordan Lewis2017-02-133-24/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | primary_keys(table) needs to query various metadata tables in Postgres to determine the primary key for the table. Previously, it did so using a complex common table expression against pg_constraint and pg_attribute. This patch simplifies the query by using information_schema tables. This simplifies the logic, making the query far easier to understand, and additionally avoids an expensive unnest, window function query, and common table expression.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The `default` arg of `index_name_exists?` is only used the adapter does not implemented `indexes`. But currently all adapters implemented `indexes` (See #26688). Therefore the `default` arg is never used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `supports_primary_key?` was added to determine if `primary_key` is implemented in the adapter in f060221. But we already use `primary_key` without `supports_primary_key?` (207f266, 5f3cf42) and using `supports_primary_key?` has been removed in #1318. This means that `supports_primary_key?` is no longer used in the internal and Active Record doesn't work without `primary_key` is implemented (all adapters must implement `primary_key`).

As we move forward the intention is to require the use of `attribute` over `attr_accessor` for more complex model behavior both on Active Record and Active Model, so this behavior is deprecated. Fixes #27956. Close #27963. [Alex Serban & Sean Griffin]

Previously, it did so using a complex common table expression against pg_constraint and pg_attribute. This patch simplifies the query by joining pg_index against pg_attribute instead of going through pg_constraint. This avoids an expensive unnest, window function query, and common table expression. EXPLAINing these queries in Postgres against a database with a single table with a composite primary key shows a 66% reduction in the plan and execute latencies. This is significant during application startup time, especially against very large schemas, where these queries would be even slower and more numerous. Closes #27949
