# From 8d89a385b71a2e4cce0fba0cfc8d91b63485edc5 Mon Sep 17 00:00:00 2001
# From: Christian Heimes <christian@python.org>
# Date: Sat, 24 Mar 2018 18:38:14 +0100
# Subject: [PATCH] [3.6] bpo-33127: Compatibility patch for LibreSSL 2.7.0
# (GH-6210) (GH-6214)
#
# LibreSSL 2.7 introduced OpenSSL 1.1.0 API. The ssl module now detects
# LibreSSL 2.7 and only provides API shims for OpenSSL < 1.1.0 and
# LibreSSL < 2.7.
# Documentation updates and fixes for failing tests will be provided in
# another patch set.
# Signed-off-by: Christian Heimes <christian@python.org>.
# (cherry picked from commit 4ca0739c9d97ac7cd45499e0d31be68dc659d0e1)
# Co-authored-by: Christian Heimes <christian@python.org>
# Patch modified by Aaron Bauman <bman@gentoo.org> for 3.5.5
