Subject: [PATCH] bpo-46623: Skip two test_zlib tests on s390x (GH-31096)
|
||||
|
||||
Skip test_pair() and test_speech128() of test_zlib on s390x since
|
||||
they fail if zlib uses the s390x hardware accelerator.

Subject: [PATCH] gh-113171: gh-65056: Fix "private" (non-global) IP address
|
||||
ranges (GH-113179) (GH-113186) (GH-118177) (GH-118472)
|
||||
|
||||
The _private_networks variables, used by various is_private
|
||||
implementations, were missing some ranges and at the same time had
|
||||
overly strict ranges (where there are more specific ranges considered
|
||||
globally reachable by the IANA registries).
|
||||
|
||||
This patch updates the ranges with what was missing or otherwise
|
||||
incorrect.
|
||||
|
||||
100.64.0.0/10 is left alone, for now, as it's been made special in [1].
|
||||
|
||||
The _address_exclude_many() call returns 8 networks for IPv4, 121
|
||||
networks for IPv6.
|
||||
|
||||
[1] https://github.com/python/cpython/issues/61602
|
||||
|
||||
In 3.10 and below, is_private checks whether the network and broadcast
|
||||
address are both private.
|
||||
In later versions (where the test wss backported from), it checks
|
||||
whether they both are in the same private network.
|
||||
|
||||
For 0.0.0.0/0, both 0.0.0.0 and 255.225.255.255 are private,
|
||||
but one is in 0.0.0.0/8 ("This network") and the other in
|
||||
255.255.255.255/32 ("Limited broadcast").
