New submission from STINNER Victor: Recently, the issue #20188 "ALPN support for TLS" was fixed. The problem is that the check for the ALPN feature doesn't work with LibreSSL:
/* ALPN added in OpenSSL 1.0.2 */ #if OPENSSL_VERSION_NUMBER >= 0x1000200fL && !defined(OPENSSL_NO_TLSEXT) # define HAVE_ALPN #endif On the buildbot OpenBSD 5.5 with LibreSSL, OPENSSL_VERSION_NUMBER is 2.x instead of 1.0.x. See also the issue #23177. A workaround would be to disable the feature if LIBRESSL_VERSION_NUMBER is defined. http://buildbot.python.org/all/builders/x86%20OpenBSD%205.5%203.x/builds/1333/steps/test/logs/stdio using PTY: False
