By using a asgiref's ThreadSensitiveContext context manager, requests
will be able to execute independently of other requests when sync work
is involved.
Prior to this commit, a single global thread was used to execute any
sync work independent of the request from which that work was scheduled.
This could result in contention for the global sync thread in the case
of a slow sync function.
Requests are now isolated to their own sync thread.
By default, this means that readline is properly registered, so that
.python_history is used.
sys.__interactivehook__ may be set by a $PYTHONSTARTUP file.
validate_ipv4_address() was affected only on Python < 3.9.5, see [1].
URLValidator() uses a regular expressions and it was affected on all
Python versions.

Moved deeply nested blocks out of inner loops to improve readability
and maintainability.
Thanks to Mariusz Felisiak, Shreyas Ravi, and Paolo Melchiorre for
feedback.
This always replaces 'fixture_name' with its base name, which preserves
the previous behavior, because os.path.basename() was not called only on
relative paths without os.path.sep i.e. when base name was equal to the
file name.
This also changes os.path.dirname() and os.path.basename() calls to the
equivalent os.path.split() call.
This moves code unable to trigger relevant exceptions outside of
try/except blocks, and changes 'objects' to 'objects_in_fixture'
which is equal to the length of 'objects'.
- Validate filename returned by FileField.upload_to() not a filename
passed to the FileField.generate_filename() (upload_to() may
completely ignored passed filename).
- Allow relative paths (without dot segments) in the generated filename.
Thanks to Jakub Kleň for the report and review.
Thanks to all folks for checking this patch on existing projects.
Thanks Florian Apolloner and Markus Holtermann for the discussion and
implementation idea.
Regression in 0b79eb36915d178aef5c6a7bbce71b1e76d376d3.
- Replaced datetime.utcnow() with datetime.now().
- Replaced datetime.utcfromtimestamp() with datetime.fromtimestamp().
- Replaced datetime.utctimetuple() with datetime.timetuple().
- Replaced calendar.timegm() and datetime.utctimetuple() with datetime.timestamp().
In Python 3.9.5+ urllib.parse() automatically removes ASCII newlines
and tabs from URLs [1, 2]. Unfortunately it created an issue in
the URLValidator. URLValidator uses urllib.urlsplit() and
urllib.urlunsplit() for creating a URL variant with Punycode which no
longer contains newlines and tabs in Python 3.9.5+. As a consequence,
the regular expression matched the URL (without unsafe characters) and
the source value (with unsafe characters) was considered valid.

This check dates back to Python <2.5, before Python introduced
BaseException to prevent exactly unwarranted catching of SystemExit
(and others).
response_for_exception() is only called under `except Exception` or
`except Http404` so it's now impossible for a SystemExit instance to
reach the branch.
