with tblib 3.2+.
tblib 3.2+ makes exception subclasses with __init__() and the default
__reduce__() picklable. This broke the test for
RemoteTestResult._confirm_picklable(), which expects a specific
exception to fail unpickling.
https://github.com/ionelmc/python-tblib/blob/master/CHANGELOG.rst#320-2025-10-21
This fix defines ExceptionThatFailsUnpickling.__reduce__() in a way
that pickle.dumps(obj) succeeds, but pickle.loads(pickle.dumps(obj))
raises TypeError.

Workers created by ParallelTestSuite were not running system
checks in the spawn multiprocessing mode. In general this is
fine, but system checks can have side effects expected by tests.
This patch runs system checks inside of _init_worker, which is
only called by ParallelTestSuite.

Thanks to Jacob Walls for the report and previous iterations of this
fix, to Simon Charette for the logging formatter idea, and to Tim Graham
for testing and ensuring that 3rd party backends remain compatible.
This partially reverts d8f093908c504ae0dbc39d3f5231f7d7920dde37.

Given there are no longer any internal usages of serialize=True and it
poses a risk to non-test databases integrity it seems appropriate to
deprecate it.
|
|
While the top-level objects fed to serialization are bound to the test
database being created nothing prevents code invoked during
serialization from performing queries against other connections entries
that haven't been swapped yet.
The reported example of that is a database router directing all reads to
a test mirror for a set of models involving auto-created many-to-many
fields. It might be tempting to address the many-to-many field case but
this a symptom of a larger problem where the test framework yields the
flow execution to user code that could interact with non-test databases
in unexpected ways.
Deferring test database fixture serialization until the point where all
connections entries have been swapped for their test equivalent ensures
that no code triggered during serialization can interact with non-test
databases.
Thanks Jake Howard for the report and Jacob Walls for the initial
investigation.

Also adds DatabaseOperations.format_debug_sql() hook for backends
(e.g. NoSQL) to customize formatting.

In these cases Black produces unexpected results, e.g.
def make_random_password(
self,

):
or
cursor.execute("""
