bpo-37463: match_hostname requires quad-dotted IPv4 (GH-14499)
 


ssl.match_hostname() no longer accepts IPv4 addresses with additional text
after the address and only quad-dotted notation without trailing
whitespaces. Some inet_aton() implementations ignore whitespace and all data
after whitespace, e.g. '127.0.0.1 whatever'.

Short notations like '127.1' for '127.0.0.1' were already filtered out.

The bug was initially found by Dominik Czarnota and reported by Paul Kehrer.

test_frozen.py 
"""Basic test of the frozen module (source is in Python/frozen.c)."""

# The Python/frozen.c source code contains a marshalled Python module
# and therefore depends on the marshal format as well as the bytecode
# format.  If those formats have been changed then frozen.c needs to be
# updated.
#
# The test_importlib also tests this module but because those tests
# are much more complicated, it might be unclear why they are failing.
# Invalid marshalled data in frozen.c could case the interpreter to
# crash when __hello__ is imported.
