* Restore the ability that SQL with binds for `insert`, `update`, and `delete` ↵Ryuta Kamizono2017-08-181-6/+6
| | | | | | | | (#29944) Since 213796f, it was lost the ability that SQL with binds for `insert`, `update`, and `delete` (like `select_all`). This restores the ability because `insert`, `update`, and `delete` are public API, so it should not be removed without deprecation.
* Restore `to_sql` to return only SQL (#29945)Ryuta Kamizono2017-08-181-4/+10
| | | | Because `to_sql` is public API. I introduced `to_sql_and_binds` internal API to return SQL and binds.

* Fix test failures when prepared statements are disabledSean Griffin2017-07-241-2/+25
| | | | | | | | | This also reverts the change to enable prepared statements by default on MySQL (though I suspect we could enable them and it'd be great). This change brings back a collector closer to the old `Bind` collector in Arel. However, this one lives in AR, since this is an AR specific need. Additionally, we only use it for statement caching, since the new substitute collector in Arel is higher performance for most cases.
* Refactor Active Record to let Arel manage bind paramsSean Griffin2017-07-241-20/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A common source of bugs and code bloat within Active Record has been the need for us to maintain the list of bind values separately from the AST they're associated with. This makes any sort of AST manipulation incredibly difficult, as any time we want to potentially insert or remove an AST node, we need to traverse the entire tree to find where the associated bind parameters are. With this change, the bind parameters now live on the AST directly. Active Record does not need to know or care about them until the final AST traversal for SQL construction. Rather than returning just the SQL, the Arel collector will now return both the SQL and the bind parameters. At this point the connection adapter will have all the values that it had before. A bit of this code is janky and something I'd like to refactor later. In particular, I don't like how we're handling associations in the predicate builder, the special casing of `StatementCache::Substitute` in `QueryAttribute`, or generally how we're handling bind value replacement in the statement cache when prepared statements are disabled. This also mostly reverts #26378, as it moved all the code into a location that I wanted to delete. /cc @metaskills @yahonda, this change will affect the adapters Fixes #29766. Fixes #29804. Fixes #26541. Close #28539. Close #24769. Close #26468. Close #26202. There are probably other issues/PRs that can be closed because of this commit, but that's all I could find on the first few pages.

* | Don't cache queries for schema statementsRyuta Kamizono2017-06-301-4/+18
|/ | | | | | `test_middleware_caches` is sometimes failed since #29454. The failure is due to schema statements are affected by query caching. Bypassing query caching for schema statements to avoid the issue.
* 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

* Deprecate `supports_statement_cache?`Ryuta Kamizono2017-05-011-2/+3
| | | | | | | | | | | | | | `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

| | | | | | | | | | | | | In Rails 5, we're much more restrictive about when we do or don't cache a prepared statement. In particular, we never cache when we are sending an IN statement or a SQL string literal However, in the case of Adequate Record, we are *always* sending a raw SQL string, and we *always* want to cache the result.
