Subject: Disable mod_http2 and mod_ssl_ct for prefork builds, since the former
X-Git-Tag: 2.5.0-alpha2-ci-test-only~1175
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=22274ab3e0b64a30912b19ff97124813916bae87;p=thirdparty%2Fapache%2Fhttpd.git

Disable mod_http2 and mod_ssl_ct for prefork builds, since the former
shouldn't be used under prefork and the latter isn't tested at all.
Possibly related to infrequent prefork child segfaults under pool-debug.

e.g. https://travis-ci.org/github/apache/httpd/jobs/736044109
is a multi-threaded prefork child dying with both mod_h2 and mod_ssl_ct
threads active.

+Known Failures
+--------------

+Some known failures:
+
+* "apt-get install" timeout/fails - workaround by moving apt install
+  to before_script phase?
+
+* prefork, and more rarely non-prefork testing sometimes catches child
+  segfaults under pool-debug from assert()s in (e.g.)
+  __pthread_tpp_change_priority where one child is destroying threads
+  which another is waiting for, or iterating through via
+  apr_pool_walk_tree().
