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)"

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.

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.

-
Previously, when building records using a

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 ahas_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...
