New Revision: 1882548

URL: http://svn.apache.org/viewvc?rev=1882548&view=rev
Log:
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().
