There is an Python test that checks the minimum TLS version - test_min_max_version (test.test_ssl.ContextTests).
Fedora 29+ sets TLSv1 as explicit minimum version. Python's test suite assumes that the minimum protocol version is set to a magic marker.
FAIL: test_min_max_version (test.test_ssl.ContextTests)

Traceback (most recent call last):
File "/builddir/build/BUILD/Python-3.7.0/Lib/test/test_ssl.py", line 1084, in test_min_max_version
ctx.minimum_version, ssl.TLSVersion.MINIMUM_SUPPORTED
AssertionError: <TLSVersion.TLSv1: 769> != <TLSVersion.MINIMUM_SUPPORTED: -2>
We currently workaround the problem by setting:
export OPENSSL_CONF=/non-existing-file
