| * Clear query cache during checkin, instead of an execution callbackMatthew Draper2016-10-273-12/+7
| | | | | | | | | | | | | | It doesn't make sense for the query cache to persist while a connection moves through the pool and is assigned to a new thread. [Samuel Cochran & Matthew Draper]
* | Avoid `unscope(:order)` when `limit_value` is presented for `count`Ryuta Kamizono2016-11-061-6/+6
| | | | | | | | | | If `limit_value` is presented, records fetching order is very important for performance. Should not unscope the order in the case.
* | Don't assign default attributes until after loading schemaSean Griffin2016-11-031-1/+1
| | | | | | | | | | | | | | | | If the call to `.define_attribute_methods` actually ends up loading the schema (*very* hard to do, as it requires the object being created without `allocate` having been called, but it can be done by manually calling `initialize` from inside `marshal_load` if you're crazy), the value of `_default_attributes` will change from that call.

* | | Allow `autosave: true` to be used with inverse ofSean Griffin2016-11-013-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the changes in #25337, double save bugs are pretty much impossible, so we can just lift this restriction with pretty much no change. There were a handful of cases where we were relying on specific quirks in tests that had to be updated. The change to has_one associations was due to a particularly interesting test where an autosaved has_one association was replaced with a new child, where the child failed to save but the test wanted to check that the parent id persisted to `nil`. I think this is almost certainly the wrong behavior, and I may change that behavior later. But ultimately the root cause was because we never remove the parent in memory when nullifying the child. This makes #23197 no longer needed, but it is what we'll do to fix some issues on 5.0 Close #23197
* | | Deprecate the behavior of AR::Dirty inside of after_(create|update|save) ↵Sean Griffin2016-11-0115-51/+276
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | callbacks We pretty frequently get bug reports that "dirty is broken inside of after callbacks". Intuitively they are correct. You'd expect `Model.after_save { puts changed? }; model.save` to do the same thing as `model.save; puts model.changed?`, but it does not. However, changing this goes much farther than just making the behavior more intuitive. There are a _ton_ of places inside of AR that can be drastically simplified with this change. Specifically, autosave associations, timestamps, touch, counter cache, and just about anything else in AR that works with callbacks have code to try to avoid "double save" bugs which we will be able to flat out remove with this change. We introduce two new sets of methods, both with names that are meant to be more explicit than dirty. The first set maintains the old behavior, and their names are meant to center that they are about changes that occurred during the save that just happened. They are equivalent to `previous_changes` when called outside of after callbacks, or once the deprecation cycle moves. The second set is the new behavior. Their names imply that they are talking about changes from the database representation. The fact that this is what we really care about became clear when looking at `BelongsTo.touch_record` when tests were failing. I'm unsure that this set of methods should be in the public API. Outside of after callbacks, they are equivalent to the existing methods on dirty. Dirty itself is not deprecated, nor are the methods inside of it. They will only emit the warning when called inside of after callbacks. The scope of this breakage is pretty large, but the migration path is simple. Given how much this can improve our codebase, and considering that it makes our API more intuitive, I think it's worth doing.

|/ / / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | delegation Following off of https://github.com/rails/rails/issues/15945, I realized that super needs to be the first thing that is called in an AbstractModel's inherited method. I was receiving errors within the inherited method of time_zone_conversion, so I tested locally by moving super to the top of the method declaration. All exceptions went away.

* | | | Clear the correct query cacheSamuel Cochran2016-10-261-4/+4
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This executor currently relies on `ActiveRecord::Base.connection` not changing between `prepare` and `complete`. If something else returns the current ActiveRecord connection to the pool early then this `complete` call will fail to clear the correct query cache and restore the original `query_cache_enabled` status. This has for example been happening in Sidekiq: https://github.com/mperham/sidekiq/pull/3166 We can just keep track of the connection as part of the exector state.

But `PolymorphicReflection` does not initialize `@delegate_reflection`. It is enough to inherit `AbstractReflection` (using `alias_candidate` only).

See gist https://gist.github.com/prathamesh-sonpatki/a7df922273473a77dfbc742a4be4b618. - This commit restores the behavior of Rails 4.2 and Rails 5.0.0 to allow passing arguments and block at the same time but also deprecates it. - Because, these arguments do not have any effect on the output of select when select is used with a block. - Updated documentation to remove the example passing arguments and block at the same time to `CollectionProxy#select`.

Type casting in the query cache method would cause the values to be type cast twice in the case that there is a cache miss (since the methods it calls will type cast *again*). If logging is disabled, then adding the type cast code to the query cache method will needlessly typecast the values (since the only reason those values are type cast is for display in the logs). Fixes #26828.
