* Improve log messages for #insert_all` / `#upsert_all` / `#insert` / `#upsert ↵Ryo Hashimoto2019-04-082-1/+53
| | | | | | | | etc. methods In #35077, `#insert_all` / `#upsert_all` / `#insert` / `#upsert` etc. methods are added. But Active Record logs only “Bulk Insert” log messages when they are invoked. This commit improves the log messages to use collect words for how invoked them.
* Don't repeat same expression in SELECT and GROUP BY clausesRyuta Kamizono2019-04-061-26/+20
| | | | | | | | | | | | | | | | | | | | | This refactors `execute_grouped_calculation` and slightly changes generated GROUP BY queries, since I'd not prefer to repeat same expression in SELECT and GROUP BY clauses. Before: ``` SELECT COUNT(*) AS count_all, "topics"."author_name" AS topics_author_name, COALESCE(type, title) AS coalesce_type_title FROM "topics" GROUP BY "topics"."author_name", COALESCE(type, title) ``` After: ``` SELECT COUNT(*) AS count_all, "topics"."author_name" AS topics_author_name, COALESCE(type, title) AS coalesce_type_title FROM "topics" GROUP BY topics_author_name, coalesce_type_title ``` Although we generally don't guarantee to support Arel node constructed by user itself, this also fixes #24207.

| * Association loading isn't to be affected by scoping consistentlyRyuta Kamizono2019-04-054-8/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Follow-up of 5c71000, #29834, and #30271. Currently, preloading and eager loading are not to be affected by scoping, with the exception of `unscoped`. But non eager loaded association access is still affected by scoping. Although this is a breaking change, the association loading will work consistently whether preloaded / eager loaded or not. Before: ```ruby Post.where("1=0").scoping do Comment.find(1).post # => nil Comment.preload(:post).find(1).post # => #<Post id: 1, ...> Comment.eager_load(:post).find(1).post # => #<Post id: 1, ...> end ``` After: ```ruby Post.where("1=0").scoping do Comment.find(1).post # => #<Post id: 1, ...> Comment.preload(:post).find(1).post # => #<Post id: 1, ...> Comment.eager_load(:post).find(1).post # => #<Post id: 1, ...> end ``` Fixes #34638. Fixes #35398.

| | | | | | | | | | | | | | | | | | | | | | | | | Originally the `JoinDependency` has the deduplication for eager loading (LEFT JOIN). This re-uses that deduplication for `left_joins`. And also, This makes left join order into part of joins, i.e.: Before: ``` association joins -> stash joins (eager loading, etc) -> string joins -> left joins ``` After: ``` association joins -> stash joins (eager loading, left joins, etc) -> string joins ``` Now string joins are able to refer left joins. Fixes #34325. Fixes #34332. Fixes #34536.

* | Fix `count(:all)` with eager loading and explicit select and orderRyuta Kamizono2019-04-043-4/+17
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This follows up ebc09ed9ad9a04338138739226a1a92c7a2707ee. We've still experienced a regression for `size` (`count(:all)`) with eager loading and explicit select and order when upgrading Rails to 5.1. In that case, the eager loading enforces `distinct` to subselect but still keep the custom select, it would cause the ORDER BY with DISTINCT issue. ``` % ARCONN=postgresql bundle exec ruby -w -Itest test/cases/relations_test.rb -n test_size_with_eager_loading_and_custom_select_and_order Using postgresql Run options: -n test_size_with_eager_loading_and_custom_select_and_order --seed 8356 # Running: E Error: RelationTest#test_size_with_eager_loading_and_custom_select_and_order: ActiveRecord::StatementInvalid: PG::InvalidColumnReference: ERROR: for SELECT DISTINCT, ORDER BY expressions must appear in select list LINE 1: ..." ON "comments"."post_id" = "posts"."id" ORDER BY comments.i... ^ ``` As another problem on `distinct` is enforced, the result of `count` becomes fewer than expected if `select` is given explicitly. e.g. ```ruby Post.select(:type).count # => 11 Post.select(:type).distinct.count # => 3 ``` As long as `distinct` is enforced, we need to care to keep the result of `count`. This fixes both the `count` with eager loading problems.
* Refactor `Relation#cache_key` is moved from ↵Ryuta Kamizono2019-04-045-54/+49
| | | | | | | | | | | | `CollectionCacheKey#collection_cache_key` The implementation of `Relation#cache_key` depends on some internal relation methods (e.g. `apply_join_dependency`, `build_subquery`), but somehow that implementation exists on the model class (`collection_cache_key`), it sometimes bothers to me. This refactors that implementation moves to `Relation#cache_key`, then we can avoid `send` to call internal methods.
* Optimizer hints should be applied on Top level query as much as possibleRyuta Kamizono2019-04-045-5/+30
| | | | | I've experienced this issue in our app, some hints only works on Top level query (e.g. `MAX_EXECUTION_TIME`).
* Don't drop internal metadata tablesRyuta Kamizono2019-04-041-4/+2
| | | | | | | | Some tests expects that internal metadata tables exists, and we should not use `create_table` in transactional tests, since DDL in MySQL causes implicit commit. https://travis-ci.org/rails/rails/jobs/515438937#L3829
* Ensure `reset_table_name` when table name prefix/suffix is changedRyuta Kamizono2019-04-044-17/+15

* Use `execute_batch2` rather than `execute_batch` to fix performance ↵Ryuta Kamizono2019-04-042-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | regression for fixture loading d8d6bd5 makes fixture loading to bulk statements by using `execute_batch` for sqlite3 adapter. But `execute_batch` is slower and it caused the performance regression for fixture loading. In sqlite3 1.4.0, it have new batch method `execute_batch2`. I've confirmed `execute_batch2` is extremely faster than `execute_batch`. So I think it is worth to upgrade sqlite3 to 1.4.0 to use that method.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * The database version will get cached in the schema cache file during the schema cache dump. When the database version check happens, the version will be pulled from the schema cache and thus avoid querying the database for the version. * If the schema cache file doesn't exist, we'll query the database for the version and cache it on the schema cache object. * To facilitate this change, all connection adapters now implement #get_database_version and #database_version. #database_version returns the value from the schema cache. * To take advantage of the cached database version, the database version check will now happen after the schema cache is set on the connection in the connection pool.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `delete_all` This partly reverts #35617. #35617 includes unused code (for `InsertStatement`) and re-using query annotation for `update_all` and `delete_all`, which has not been discussed yet. If a relation has any annotation, I think it is mostly for SELECT query, so re-using annotation by default is not always desired behavior for me. We should discuss about desired behavior before publishing the implementation.
