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.

2021-10-12Fixed #28401 -- Allowed hashlib.md5() calls to work with FIPS kernels.Ade Lee
md5 is not an approved algorithm in FIPS mode, and trying to instantiate a hashlib.md5() will fail when the system is running in FIPS mode. md5 is allowed when in a non-security context. There is a plan to add a keyword parameter (usedforsecurity) to hashlib.md5() to annotate whether or not the instance is being used in a security context. In the case where it is not, the instantiation of md5 will be allowed. See https://bugs.python.org/issue9216 for more details. Some downstream python versions already support this parameter. To support these versions, a new encapsulation of md5() has been added. This encapsulation will pass through the usedforsecurity parameter in the case where the parameter is supported, and strip it if it is not.

2019-12-11Refs #28373 -- Stopped setting tzinfo in typecast_timestamp().Sergey Fedoseev
Unnecessary since cef3f2d3c64055c9fc1757fd61dba24b557a2add. When USE_TZ=True, conn_tznames is always passed to methods that use typecast_timestamp(). Therefore, it can return naive datetimes.
2019-05-08Used time.monotonic() instead of time.time() where applicable.Przemysław Suliga
time.monotonic() available from Python 3.3: - Nicely communicates a narrow intent of "get a local system monotonic clock time" instead of possible "get a not necessarily accurate Unix time stamp because it needs to be communicated to outside of this process/machine" when time.time() is used. - Its result isn't affected by the system clock updates. There are two classes of time.time() uses changed to time.monotonic() by this change: - measuring time taken to run some code. - setting and checking a "close_at" threshold for for persistent db connections (django/db/backends/base/base.py).
