* Ensure `clear_cache!` clears the prepared statements cacheRyuta Kamizono2019-03-065-26/+25
| | | | | | | | | | | Since #23461, all adapters supports prepared statements, so that clears the prepared statements cache is no longer database specific. Actually, I struggled to identify the cause of random CI failure in #23461, that was missing `@statements.clear` in `clear_cache!`. This extracts `clear_cache!` to ensure the common concerns in the abstract adapter.
* Add insert_all to ActiveRecord models (#35077)Bob Lail2019-03-0512-17/+613
| | | | | Adds a method to ActiveRecord allowing records to be inserted in bulk without instantiating ActiveRecord models. This method supports options for handling uniqueness violations by skipping duplicate records or overwriting them in an UPSERT operation. ActiveRecord already supports bulk-update and bulk-destroy actions that execute SQL UPDATE and DELETE commands directly. It also supports bulk-read actions through `pluck`. It makes sense for it also to support bulk-creation.
* Reset `connection_handlers` to default when any test dirties thatRyuta Kamizono2019-03-051-0/+4
| | | | | | | | | Most existing tests expects `connection_handlers` has only one default handler, but the test added at #34779 dirties that. We need to reset `connection_handlers` to default in that case. Closes #35471.

| * Copy the forking isolated test runner from railtiesMatthew Draper2019-03-051-2/+38
| | | | | | | | | | | | All the tests have a substantial chunk of identical setup effort (in cases/helper.rb); this makes isolated tests run much faster, without any change to the variety of how we load files.
* | Allow `truncate` for SQLite3 adapter and add `rails db:seed:replant` (#34779)Bogdan2019-03-049-0/+213
| | | | | | | | | | | | | | | | | | | | | | | | | | * Add `ActiveRecord::Base.connection.truncate` for SQLite3 adapter. SQLite doesn't support `TRUNCATE TABLE`, but SQLite3 adapter can support `ActiveRecord::Base.connection.truncate` by using `DELETE FROM`. `DELETE` without `WHERE` uses "The Truncate Optimization", see https://www.sqlite.org/lang_delete.html. * Add `rails db:seed:replant` that truncates database tables and loads the seeds Closes #34765

* | Deprecate mismatched collation comparison for uniquness validatorRyuta Kamizono2019-03-046-12/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In MySQL, the default collation is case insensitive. Since the uniqueness validator enforces case sensitive comparison by default, it frequently causes mismatched collation issues (performance, weird behavior, etc) to MySQL users. https://grosser.it/2009/12/11/validates_uniqness_of-mysql-slow/ https://github.com/rails/rails/issues/1399 https://github.com/rails/rails/pull/13465 https://github.com/gitlabhq/gitlabhq/commit/c1dddf8c7d947691729f6d64a8ea768b5c915855 https://github.com/huginn/huginn/pull/1330#discussion_r55152573 I'd like to deprecate the implicit default enforcing since I frequently experienced the problems in code reviews. Note that this change has no effect to sqlite3, postgresql, and oracle-enhanced adapters which are implemented as case sensitive by default, only affect to mysql2 adapter (I can take a work if sqlserver adapter will support Rails 6.0).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | #35360 allows table name qualified if `from` has original table name. But that is still too strict. We have a valid use case that `from` with INDEX hint (e.g. `from("comments USE INDEX (PRIMARY)")`). So I've relaxed the table name detection in `from` to allow any extension like INDEX hint. Fixes #35359.
