Hi there, Yesterday I was trying to play with the http2 module on Apache from ports, as I saw it was added to the ports file list. The problem is that the module isnt working correctly.
If you try it on a http vhost, it simply returns the page via the normal way (http). And if you enable it on a https vhost, the vhost stops working (doesnt serve anything). So I went to https://httpd.apache.org/dev/debugging.html , and saw the instructions on how to debug Apache, and ran httpd2 on gdb with the -X option. After a few requests, httpd2 segfaults, but only when using the "mpm_prefork" module. With "mpm_event" or "mpm_worker" it doesnt crash. # gdb --args httpd2 -X (gdb) run Starting program: /usr/local/sbin/httpd2 -X AH00557: httpd2: apr_sockaddr_info_get() failed for web.my.domain AH00558: httpd2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1. Set the 'ServerName' directive globally to suppress this message Program received signal SIGSEGV, Segmentation fault. 0x000014a785962a1b in ap_mpm_pod_check () from /usr/local/sbin/httpd2 (gdb) bt #0 0x000014a785962a1b in ap_mpm_pod_check () from /usr/local/sbin/httpd2 #1 0x000014aa29a81f9e in child_main () from /usr/local/lib/apache2/mod_mpm_prefork.so #2 0x000014aa29a82321 in make_child () from /usr/local/lib/apache2/mod_mpm_prefork.so #3 0x000014aa29a833cf in prefork_run () from /usr/local/lib/apache2/mod_mpm_prefork.so #4 0x000014a785937d12 in ap_run_mpm () from /usr/local/sbin/httpd2 #5 0x000014a7859318b3 in main () from /usr/local/sbin/httpd2 And if you run httpd2 -X and try to access an SSL vhost it also crashes.

() I dont know if this is expected on OpenBSD or already known, if it is, please ignore this message. This is making debugging Apache to figure out why http2 isnt working impossible. Regards.
