Ryuta Kamizono 67a4a9feb9 Prevent making bind param if casted value is nil 
If casted value is nil, generated SQL should be `IS NULL`. But currently
it is generated as `= NULL`. To prevent this behavior, avoid making bind
param if casted value is nil.

Fixes #28945.

  • Loading model schema from database is now thread-safe.

    Fixes #28589.

  • 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+

  • 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.

  • Fix inconsistency with changed attributes when overriding AR attribute reader.

  • 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.
