| | | | | | | | | | | | | | r1821607, r1821608. Instead of copying event/fdqueue.c code into existing mpm_unix.c, losing all contributors (blame, since r105919...), will restart the series by svn-moving event/fdqueue.[ch] to server/mpm_fdqueue.[ch] first. The code is not really unix specific either, so this sounds better. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1821619 13f79535-47bb-0310-9956-ffa450edef68

* core, MPMs unix: follow up to r1809881.Yann Ylavic2017-09-281-0/+29
| | | | | | | | | | | | | | | | | | Deregister all hooks first (in pre_cleanup), by doing it last we could still have had them run when DSOs were unloaded. Likewise, avoid double faults when handling fatal signals by restoring the default handler before pconf is cleared (we can't ap_log_error there). Finally, we need to ignore sig_term/restart (do nothing) when the main process is exiting (i.e. ap_pglobal is destroyed), since retained_data are freed. Aimed to fix all faults in PR 61558. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1809973 13f79535-47bb-0310-9956-ffa450edef68

* MPMs, core: make duplicated listeners (SO_REUSEPORT) introduced in r1599531Yann Ylavic2014-10-301-77/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | less intrusive. Submitted by: Yingqi Lu <yingqi.lu@intel.com> Modified/Committed by: ylavic Add ListenCoresBucketsRatio which is a configurable ratio between the number of CPU cores (online) and the number of listeners buckets to create, defaulting to zero (so that listeners buckets become an opt-in, ie. ncpus / ratio > 1). This could also be made an opt-out by using the previous hardcoded value (8) as default. Make ap_close_listeners() act on all the listeners (including duplicated ones), since the function is also called externally (eg. mod_cgid, mod_ssl_ct and possibly any third party module) to cleanup opened descriptors when a process is forked (the duplicated listeners are kept in a scoped/static variable). Add ap_close_listeners_ex() to close a single bucket of listeners, used by the children to close unused duplicates and internally by ap_close_listeners(). Make ap_duplicate_listeners() compute the number of buckets to be used, instead of each MPM. This number is now based on the above ratio and will not change unless asked to (given *num_buckets < 1, that is when the MPM does not run in one-process mode nor after a graceful restart). Remove some global variables (mpm_listen, enable_default_listeners) previously used to communicate between MPMs and ap_listen, since ap_duplicate_listeners() API can now be used to do so. Also rename num_buckets as ap_num_listen_buckets, and prefix have_so_reuseport with ap_ (both printed by ap_log_common(), hence kept global). Detect ap_have_so_reuseport once only at startup. Restore dummy_connection() as before r1599531 since sending POD signals should not depend on the number of listeners buckets (there is still one single socket receiving the connections). For each MPM (concerned), move the bucket data (pod, listeners and eventually accept mutex) into a struct and instanciate an array of them (sized by the number of buckets), for each child to use its own data according to its bucket index, and the parent to maintain the whole. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1635521 13f79535-47bb-0310-9956-ffa450edef68
