| | | | | | | | | | | | | | | | | | We can revert migrations using `change_column_comment` or `change_table_comment` at current master. However, results are not what we expect: comments are remained in new status. This change tells previous comment to these methods in a way like `change_column_default`.
* | Refactor `sync_with_transaction_state`Ryuta Kamizono2019-04-151-8/+14
| | | | | | | | | | | | | | All transaction states (:committed, :fully_committed, :rolledback, :fully_rolledback) are mutually exclusive. And also, `force_clear_transaction_record_state` should clear `@transaction_state` as well.

* | Don't expose `add_to_transaction`Ryuta Kamizono2019-04-142-14/+8
|/ | | | | | | | | | | | | | `add_to_transaction` was added at da840d1, but it should not be called by except internal, since `remember_transaction_record_state` should be called only once before saving. And also, currently `add_to_transaction` doesn't always add the record to transaction since da8de91, that is the reason hard to use that even in internal. Even if `add_to_transaction` ensure to add the record to transaction, that is an internal concern, people don't need to explicitly call `add_to_transaction`.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Running this migration on mysql at current master fails because `add_references_for_alter` is missing. ``` change_table :users, bulk: true do |t| t.references :article end ``` This is also true for postgresql adapter, but its `bulk_alter_table` implementation can fallback in such case. postgresql's implementation is desirable to prevent unknown failure like this.
* | Improve wording of commentsChris Salzberg2019-04-133-3/+3
|/ | | | | | Most of the time, these methods are called from actual methods defined from columns in the schema, not from method_missing, so the current wording is misleading.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 58410b3d566e6b93c7b71c0eec0fc11ec906b68e. If we have any implicit commit/rollback callbacks, it is necessary to add record to transaction explicitly like `:touch_deferred_attributes`. https://github.com/rails/rails/blob/5f261d04d6f857d49c75124df809adfbd6cd5b5e/activerecord/lib/active_record/touch_later.rb#L9 https://github.com/rails/rails/blob/5f261d04d6f857d49c75124df809adfbd6cd5b5e/activerecord/lib/active_record/touch_later.rb#L25 But I can't find any other implicit commit/rollback callbacks in our code base at least now. I think the `self.class.connection.add_transaction_record(self)` line doesn't cover any behavior.

| |/ | | | | | | | | | | | | | | | | | | | | Regardless of a record isn't saved (e.g. validation is failed), `after_commit` / `after_rollback` callbacks are invoked for now. To fix the issue, this adds a record to the current transaction only when a record is actually saved. Fixes #29747. Closes #29833.

As long as attributes backed dirty tracking is used, ivar backed dirty tracking should not need to be performed. I've refactored to extract new `ForcedMutationTracker` which only tracks `force_change` to be performed for ivar backed dirty tracking, that makes dirty tracking on Active Record 2x ~ 30x faster. https://gist.github.com/kamipo/971dfe0891f0fe1ec7db8ab31f016435 Before: ``` Warming up -------------------------------------- changed? 4.467k i/100ms changed 5.134k i/100ms changes 3.023k i/100ms changed_attributes 4.358k i/100ms title_change 3.185k i/100ms title_was 3.381k i/100ms Calculating ------------------------------------- changed? 42.197k (±28.5%) i/s - 187.614k in 5.050446s changed 50.481k (±16.0%) i/s - 246.432k in 5.045759s changes 30.799k (± 7.2%) i/s - 154.173k in 5.030765s changed_attributes 51.530k (±14.2%) i/s - 252.764k in 5.041106s title_change 44.667k (± 9.0%) i/s - 222.950k in 5.040646s title_was 44.635k (±16.6%) i/s - 216.384k in 5.051098s ``` After: ``` Warming up -------------------------------------- changed? 24.130k i/100ms changed 13.503k i/100ms changes 6.511k i/100ms changed_attributes 9.226k i/100ms title_change 48.221k i/100ms title_was 96.060k i/100ms Calculating ------------------------------------- changed? 245.478k (±16.1%) i/s - 1.182M in 5.015837s changed 157.641k (± 4.9%) i/s - 796.677k in 5.066734s changes 70.633k (± 5.7%) i/s - 358.105k in 5.086553s changed_attributes 95.155k (±13.6%) i/s - 470.526k in 5.082841s title_change 566.481k (± 3.5%) i/s - 2.845M in 5.028852s title_was 1.487M (± 3.9%) i/s - 7.493M in 5.046774s ```

Prior to this PR, when there was a circular series of `autosave: true` associations, the callback for a `has_many` association was run while another instance of the same callback on the same association hadn't finished running. When control returned to the first instance of the callback, the instance variable had changed, and subsequent associated records weren't saved correctly. Specifically, the ID field for the `belongs_to` corresponding to the `has_many` was `nil`. Remove unnecessary test and comments. Fixes #28080.

An example case: ↳ app/controllers/example_controller.rb:23 (0.2ms) begin transaction ↳ app/controllers/example_controller.rb:39 Example Exists (0.2ms) SELECT 1 AS one FROM "examples" WHERE "examples"."field" IS NULL AND "examples"."parent_id" = ? LIMIT ? [["parent_id", 123], ["LIMIT", 1]] ↳ app/controllers/example_controller.rb:39 (0.1ms) rollback transaction To me, a Rails newbie, this parsed as the following: - started the transaction to create a thing - found that your object exists already! - so we rolled back the transaction (even though the actual cause of the transaction is something that happens after the Exists check.) All this does is add a question mark to the message, to make it clear in the log that this is a check, not a confirmation. This may be kind of silly, but it may save some future goofs by newbs like me.

* | | | Don't repeat same expression in SELECT and GROUP BY clausesRyuta Kamizono2019-04-061-26/+20

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.
