* | | | Abandon TOP support.Vladimir Kochnev2018-09-257-23/+2
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initially, `TOP` was introduced to support `limit` for MSSQL database. Unlike PostgreSQL/MySQL/SQLite, MSSQL does not have native `LIMIT`/`OFFSET` support. The commit adding `TOP` is 1a246f71616cf246a75ef6cbdb56032e43d4e643. However, it figured out that `TOP` implementation was weak and it's not sufficient to also support `OFFSET`, then `TOP` was substituted with `ROW_NUMBER()` subquery in be48ed3071fd6524d0145c4ad3faeb4aafe3eda3. This is a well known trick in MSSQL - https://stackoverflow.com/questions/2135418/equivalent-of-limit-and-offset-for-sql-server. So now we don't need this `visit_Arel_Nodes_Top` at all. It does nothing useful but also adds an extra space after `SELECT` when `LIMIT` is being used for **any** database.
* | | Eagerly define attribute methods in productionEugene Kenny2018-09-241-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The attribute methods for a model are currently defined lazily the first time that model is instantiated, even when `config.eager_load` is true. This means the first request to use each model incurs the cost, which usually involves a database round trip to fetch the schema definition. By defining the attribute methods for all models while the application is booting, we move that work out of any individual request. When using a forking web server, this also reduces the number of times the schema definition is queried by doing it once in the parent process instead of from each forked process during their first request.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | does not support it If you are using the "in cache versioning" also known as "recyclable cache keys" the cache store must be aware of this scheme, otherwise you will generate cache entries that never invalidate. This PR adds a check to the initialization process to ensure that if recyclable cache keys are being used via ``` config.active_record.cache_versioning = true ``` Then the cache store needs to show that it supports this versioning scheme. Cache stores can let Rails know that they support this scheme by adding a method `supports_in_cache_versioning?` and returning true.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When column_defaults is called it calls `value` on each instance of Attribute inside the _default_attributes set. Since value is memoized in the Attribute instance and that Attribute instance is shared across all instances of a model the next call to the default value will be memozied not running the proc defined by the user. Fixes #33031.

I would prefer to make `to_a` as alias to the `to_ary` because: - It would be clear for users from https://edgeapi.rubyonrails.org/classes/ActiveRecord/Result.html that `to_a` and `to_ary` are the same - For us it would take less efforts in case if we needed to change the docs or implementation, since the methods are the same Follow up #33912

Past attempts: #9236, #14849, #23357. All existing counter cache issues (increment/decrement twice, lost increment) are caused due to updating counter cache on the outside of the record saving transaction by assigning belongs_to record, even though assigning that doesn't cause the record saving. We have the `@_after_replace_counter_called` guard condition to mitigate double increment/decrement issues, but we can't completely prevent that inconsistency as long as updating counter cache on the outside of the transaction, since saving the record is not always happened after that. We already have handling counter cache after create/update/destroy, https://github.com/rails/rails/blob/1b90f614b1b3d06b7f02a8b9ea6cd84f15d58643/activerecord/lib/active_record/counter_cache.rb#L162-L189 https://github.com/rails/rails/blob/1b90f614b1b3d06b7f02a8b9ea6cd84f15d58643/activerecord/lib/active_record/associations/builder/belongs_to.rb#L33-L59 so just removing assigning logic on the belongs_to association makes counter cache transactional completely. Closes #14849. Closes #23357. Closes #31493. Closes #31494. Closes #32372. Closes #33113. Closes #33117 Closes #33129. Closes #33458.
