Bumps sqlalchemy from 1.3.24 to 1.4.38.

Release notes

Sourced from sqlalchemy's releases.

1.4.38

Released: June 23, 2022

orm

• [orm] [bug] [regression] Fixed regression caused by #8064 where a particular check for column correspondence was made too liberal, resulting in incorrect rendering for some ORM subqueries such as those using PropComparator.has() or PropComparator.any() in conjunction with joined-inheritance queries that also use legacy aliasing features.

  References: #8162

• [orm] [bug] [sql] Fixed an issue where _sql.GenerativeSelect.fetch() would not be applied when executing a statement using the ORM.

  References: #8091

• [orm] [bug] Fixed issue where a _orm.with_loader_criteria() option could not be pickled, as is necessary when it is carried along for propagation to lazy loaders in conjunction with a caching scheme. Currently, the only form that is supported as picklable is to pass the "where criteria" as a fixed module-level callable function that produces a SQL expression. An ad-hoc "lambda" can't be pickled, and a SQL expression object is usually not fully picklable directly.

  References: #8109

engine

• [engine] [bug] Repaired a deprecation warning class decorator that was preventing key objects such as _engine.Connection from having a proper __weakref__ attribute, causing operations like Python standard library inspect.getmembers() to fail.

  References: #8115

sql

• [sql] [bug] Fixed multiple observed race conditions related to lambda_stmt(), including an initial "dogpile" issue when a new Python code object is initially analyzed among multiple simultaneous threads which created both a performance issue as well as some internal corruption of state. Additionally repaired observed race condition which could occur when "cloning" an expression construct that is also in the process of being compiled or otherwise accessed in a different thread due to memoized
