Fix bin/rails db:migrate with specified VERSION. bin/rails db:migrate with empty VERSION behaves as without VERSION. Check a format of VERSION: Allow a migration version number or name of a migration file. Raise error if format of VERSION is invalid. Raise error if target migration doesn't exist.

Before:

$ RAILS_ENV=test rails dbconsole

Fix COUNT(DISTINCT ...) for GROUP BY with ORDER BY and LIMIT.

Fixes #30886.

PostgreSQL tsrange now preserves subsecond precision.

PostgreSQL 9.1+ introduced range types, and Rails added support for using this datatype in Active Record. However, the serialization of PostgreSQL::OID::Range was incomplete, because it did not properly cast the bounds that make up the range. This led to subseconds being dropped in SQL commands:

Before:
```
connection.type_cast(tsrange.serialize(range_value))
# => "[2010-01-01 13:30:00 UTC,2011-02-02 19:30:00 UTC)"
```
Now:
```
connection.type_cast(tsrange.serialize(range_value))
# => "[2010-01-01 13:30:00.670277,2011-02-02 19:30:00.745125)"
```
Thomas Cannon

Ensure sum honors distinct on has_many :through associations

Fixes #16791.

Aaron Wortham
Add binary fixture helper method.

Atsushi Yoshida
When using Relation#or, extract the common conditions and put them before the OR condition.

Maxime Handfield Lapointe
Relation#or now accepts two relations who have different values for references only, as references can be implicitly called by where.

Fixes #29411.

Sean Griffin
ApplicationRecord is no longer generated when generating models. If you need to generate it, it can be created with rails g application_record.

Lisa Ugray
Fix COUNT(DISTINCT ...) with ORDER BY and LIMIT to keep the existing select list.

Ryuta Kamizono
When a has_one association is destroyed by dependent: destroy, destroyed_by_association will now be set to the reflection, matching the behaviour of has_many associations.

Lisa Ugray

Fix unscoped(where: [columns]) removing the wrong bind values

When the where is called on a relation after a or, unscoping the column of that later where removed bind values used by the or instead. (possibly other cases too)

Post.where(id: 1).or(Post.where(id: 2)).where(foo: 3).unscope(where: :foo).to_sql
# Currently:
#     SELECT "posts".* FROM "posts" WHERE ("posts"."id" = 2 OR "posts"."id" = 3)
# With fix:
#     SELECT "posts".* FROM "posts" WHERE ("posts"."id" = 1 OR "posts"."id" = 2)

Maxime Handfield Lapointe

Values constructed using multi-parameter assignment will now use the post-type-cast value for rendering in single-field form inputs.

Sean Griffin
Relation#joins is no longer affected by the target model's current_scope, with the exception of unscoped.

Fixes #29338.

Sean Griffin
Change sqlite3 boolean serialization to use 1 and 0

SQLite natively recognizes 1 and 0 as true and false, but does not natively recognize 't' and 'f' as was previously serialized.

This change in serialization requires a migration of stored boolean data for SQLite databases, so it's implemented behind a configuration flag whose default false value is deprecated.

Lisa Ugray
Skip query caching when working with batches of records (find_each, find_in_batches, in_batches).

Previously, records would be fetched in batches, but all records would be retained in memory until the end of the request or job.

Eugene Kenny
Prevent errors raised by sql.active_record notification subscribers from being converted into ActiveRecord::StatementInvalid exceptions.

Dennis Taylor
Fix eager loading/preloading association with scope including joins.

Fixes #28324.

Ryuta Kamizono
Fix transactions to apply state to child transactions

Previously, if you had a nested transaction and the outer transaction was rolledback, the record from the inner transaction would still be marked as persisted.

This change fixes that by applying the state of the parent transaction to the child transaction when the parent transaction is rolledback. This will correctly mark records from the inner transaction as not persisted.

Eileen M. Uchitelle, Aaron Patterson
Deprecate set_state method in TransactionState

Deprecated the set_state method in favor of setting the state via specific methods. If you need to mark the state of the transaction you can now use rollback!, commit! or nullify! instead of set_state(:rolledback), set_state(:committed), or set_state(nil).

Eileen M. Uchitelle, Aaron Patterson
Deprecate delegating to arel in Relation.

Ryuta Kamizono
Fix eager loading to respect store_full_sti_class setting.

Ryuta Kamizono
Query cache was unavailable when entering the ActiveRecord::Base.cache block without being connected.

Tsukasa Oishi
Previously, when building records using a has_many :through association, if the child records were deleted before the parent was saved, they would still be persisted. Now, if child records are deleted before the parent is saved on a has_many :through association, the child records will not be persisted.

Tobias Kraze

Merging two relations representing nested joins no longer transforms the joins of the merged relation into LEFT OUTER JOIN. Example to clarify:

Author.joins(:posts).merge(Post.joins(:comments))
# Before the change:
#=> SELECT ... FROM authors INNER JOIN posts ON ... LEFT OUTER JOIN comments ON...

# After the change:
#=> SELECT ... FROM authors INNER JOIN posts ON ... INNER JOIN comments ON...

TODO: Add to the Rails 5.2 upgrade guide

ActiveRecord::Persistence#touch does not work well when optimistic locking enabled and locking_column, without default value, is null in the database.

bogdanvlviv
Fix destroying existing object does not work well when optimistic locking enabled and locking_column is null in the database.

bogdanvlviv
Use bulk INSERT to insert fixtures for better performance.

Kir Shatrov
Prevent creation of bind param if casted value is nil.

Ryuta Kamizono
Deprecate passing arguments and block at the same time to count and sum in ActiveRecord::Calculations.

Ryuta Kamizono
Loading model schema from database is now thread-safe.

Fixes #28589.

Vikrant Chaudhary, David Abdemoulaie
Add ActiveRecord::Base#cache_version to support recyclable cache keys via the new versioned entries in ActiveSupport::Cache. This also means that ActiveRecord::Base#cache_key will now return a stable key that does not include a timestamp any more.

NOTE: This feature is turned off by default, and #cache_key will still return cache keys with timestamps until you set ActiveRecord::Base.cache_versioning = true. That's the setting for all new apps on Rails 5.2+

DHH
Respect SchemaDumper.ignore_tables in rake tasks for databases structure dump

Rusty Geldmacher, Guillermo Iguaran
Add type caster to RuntimeReflection#alias_name

Fixes #28959.

Jon Moss
Deprecate supports_statement_cache?.

Ryuta Kamizono
Raise error UnknownMigrationVersionError on the movement of migrations when the current migration does not exist.

bogdanvlviv
Fix bin/rails db:forward first migration.

bogdanvlviv
Support Descending Indexes for MySQL.

MySQL 8.0.1 and higher supports descending indexes: DESC in an index definition is no longer ignored. See https://dev.mysql.com/doc/refman/8.0/en/descending-indexes.html.

Ryuta Kamizono
Fix inconsistency with changed attributes when overriding AR attribute reader.

bogdanvlviv
When calling the dynamic fixture accessor method with no arguments, it now returns all fixtures of this type. Previously this method always returned an empty array.
