= New Features
* A temporarily_release_connection Database extension has been added,
designed for multithreaded transactional testing.
This allows one thread to start a transaction, and then release
the connection back for usage by the connection pool, so that
other threads can operate on the connection object safely inside
the transaction. This requires the connection pool be limited
to a single connection, to ensure that the released connection
can be reacquired. It's not perfect, because if the connection
is disconnected and removed from the pool while temporarily
released, there is no way to handle that situation correctly.
Example:
DB.transaction(rollback: :always, auto_savepoint: true) do |conn|
DB.temporarily_release_connection(conn) do
# Other threads can operate on connection safely inside
# the transaction
yield
end
end
= Other Improvements
* In the caller_logging and provenance extensions, Ruby internal
caller locations are skipped when trying to locate the appropriate
caller line to include.
* A couple ignored block warnings in plugin apply methods have been
fixed on Ruby 3.4.
