|\ | | | | Sync transaction state when accessing primary key
| * Sync transaction state when accessing primary keyEugene Kenny2017-07-093-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a record is modified inside a transaction, it must check the outcome of that transaction before accessing any state which would no longer be valid if it was rolled back. For example, consider a new record that was saved inside a transaction which was later rolled back: it should be restored to its previous state so that saving it again inserts a new row into the database instead of trying to update a row that no longer exists. The `id` and `id=` methods defined on the PrimaryKey module implement this correctly, but when a model uses a custom primary key, the reader and writer methods for that attribute must check the transaction state too. The `read_attribute` and `write_attribute` methods also need to check the transaction state when accessing the primary key.

| * | | Building `where_clause` in `UniquenessValidator` is no longer neededRyuta Kamizono2017-07-261-4/+1
| |/ / | | | | | | | | | | | | | | | Building `where_clause` manually was introduced at #26073 to include both `comparison` and `binds` in `where_clause`. Since 213796f, `comparison` includes `binds`, so it is enough to use `where` simply.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were expecting those classes to be loaded when an association is defined but they are not. If you add a debugger on the first line of any of those classes and try to define the corresponding association you will see that the classes are not loaded. Fixes #26273

|/ / | | | | | | | | | | | | Anywhere that we're doing `self.class.unscoped.where(primary_key => id)` is somewhere that someone may want to extend. Even if this method isn't public API yet, this will make it easier for us to eventually expose an API around this. Plus, duplicated code makes me sad.

|/ / | | | | | | | | | | | | | | | | Note that the two relations must still have the same `includes` values (which is the only time `references` actually does anything). It makes sense for us to allow this, as `references` is called implicitly when passing a hash to `where`. Fixes #29411

* / / Stop creating ApplicationRecord on model generationLisa Ugray2017-07-243-23/+26
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | When generating models, we created ApplicationRecord in the default location if no file existed there. That was annoying for people who moved it to somewhere else in the autoload path. At this point, the vast majority of apps should have either run the upgrade script or generated a model since upgrading. For those that haven't the error message after generating a new model should be helpful: NameError: uninitialized constant ApplicationRecord To ease friction in that case, this also adds a generator for ApplicationRecord.

| | | | | | | | | | | | | | | | | | | | | Since #26972, `ORDER BY` is kept if `LIMIT` is presented for performance. But in most SQL servers (e.g. PostgreSQL, SQL Server, etc), `ORDER BY` expressions must appear in select list for `SELECT DISTINCT`. We should not replace existing select list in that case.

|\ \ \ | | | | | | | | Fix `counter_cache` double increment
| * | | Add test for fixed `counter_cache` double incrementLisa Ugray2017-07-192-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an `after_create` callback did `update_attributes` on a record with multiple `belongs_to` associations with counter caches, even numbered associations would have their counters double-incremented. Fixes to `ActiveModel::Dirty` in 020abad fixed this. This adds regression tests for this bug fixed incidentally in the other commit, which also removed the need for the workaround using @_after_create_counter_called.
* | | | Fix test failures when prepared statements are disabledSean Griffin2017-07-243-14/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | | | Fix build failures on PGSean Griffin2017-07-241-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Honestly I don't think the tests that are fixed by this change should have been merged. Passing a range or an array to `where` has a special meaning. We need to solve the problem more concretely without overriding the behavior that is present for *every* other type. However, the damage has been done. These changes were in 5.1, so we need a deprecation cycle to remove it.
* | | | Fix build failures on MySQLSean Griffin2017-07-242-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | There's an actual bug in 213796fb4936dce1da2f0c097a054e1af5c25c2c around prepared statements being disabled. I'm looking into it, but in the mean time this gets the build green so it doesn't block other PRs
* | | | Refactor Active Record to let Arel manage bind paramsSean Griffin2017-07-2426-329/+225
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | | | Avoid modifying frozen string in check_schema_fileEugene Kenny2017-07-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This was missed when the frozen string literal pragma was added to this file because the string is only modified when running in the context of a full Rails app, which wasn't covered by the test suite.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The list of enabled adapter extensions in the schema dump isn't sorted by default, so it may happen that the sorting changes over time. If you're using a VCS, a change to the sorting results in a diff without any real change. Sorting the list should solve this problem.

| |/ / / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `type_map` is an internal API and it is only used in the connection adapter. And also, some type map initializer methods requires passed `type_map`, but those instances already has `type_map` in itself. So we don't need explicit passing `type_map` to the initializers.

| |/ / / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a has_many association is destroyed by `dependent: destroy`, destroyed_by_association is set to the reflection, and this can be checked in callbacks. This matches that behaviour for has_one associations.
