- t/modules/http2.t fails when the server is build using OpenSSL
0.9.8zh with the "Bad plan. You planned 52 tests..." message
indicating, that h2 using TLS does not work. It happens on all
platforms, but not if the client also uses OpenSSL 0.9.8zh.
I don't know whether that is expected for old OpenSSL, so can not
judge on criticality.
AFAICT, correct me if I am wrong, OpenSSL 0.9.8 does not support
TLSv1.2 and is therefore unusable with h2. The test suite seems to be
unprepared for this scenario. I will remove it after the next
release. It is not worth fixing in its current form.
I added a check agains the test suite OpenSSL version in r1844483.
I have an aditional check for the server version available.
Unfortunately I didn't find a really easy way, so here's a small
module that one can query
(c-modules/test_ssl_version/mod_test_ssl_version.c), mostly a
shortened form of mod_test_ssl.c:
