[dependabot]

Bumps sqlalchemy from 2.0.21 to 2.0.28.

Release notes

Sourced from sqlalchemy's releases.

2.0.28

Released: March 4, 2024

orm

• [orm] [performance] [bug] [regression] Adjusted the fix made in #10570, released in 2.0.23, where new logic was added to reconcile possibly changing bound parameter values across cache key generations used within the _orm.with_expression() construct. The new logic changes the approach by which the new bound parameter values are associated with the statement, avoiding the need to deep-copy the statement which can result in a significant performance penalty for very deep / complex SQL constructs. The new approach no longer requires this deep-copy step.

• [orm] [bug] [regression] Fixed regression caused by #9779 where using the "secondary" table in a relationship and_() expression would fail to be aliased to match how the "secondary" table normally renders within a _sql.Select.join() expression, leading to an invalid query.

  References: #11010

engine

• [engine] [usecase] Added new core execution option _engine.Connection.execution_options.preserve_rowcount. When set, the cursor.rowcount attribute from the DBAPI cursor will be unconditionally memoized at statement execution time, so that whatever value the DBAPI offers for any kind of statement will be available using the _engine.CursorResult.rowcount attribute from the _engine.CursorResult. This allows the rowcount to be accessed for statments such as INSERT and SELECT, to the degree supported by the DBAPI in use. The engine_insertmanyvalues also supports this option and will ensure _engine.CursorResult.rowcount is correctly set for a bulk INSERT of rows when set.

  References: #10974

asyncio

• [asyncio] [bug] An error is raised if a QueuePool or other non-asyncio pool class is passed to _asyncio.create_async_engine(). This engine only accepts asyncio-compatible pool classes including AsyncAdaptedQueuePool. Other pool classes such as NullPool are compatible with both synchronous and asynchronous
