* MPMs unix: bind the bucket number of each child to its slot numberYann Ylavic2019-03-121-1/+4
| | | | | | | | | | | | | We need not remember each child's bucket number in SHM for restarts, for the lifetime of the httpd main process the bucket number can be bound to the slot number such that: bucket = slot % num_buckets. This both simplifies the logic and helps children maintenance per bucket in threaded MPMs, where previously perform_idle_server_maintenance() could create or kill children processes for the buckets it was not in charge of. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1855306 13f79535-47bb-0310-9956-ffa450edef68

* Some improvements for handling of many connections for MPM event:Stefan Fritsch2011-06-191-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Process lingering close asynchronously instead of tying up worker threads (based on patch by Jeff Trawick). - If the number of connections of a process is above threads_per_child + WORKER_OVERCOMMIT * (idle_workers - 1) (WORKER_OVERCOMMIT is fixed at 2, at the moment), or if all workers are busy, don't accept new connections in that process. Such a dynamic connection limit is necessary because we may have both async and non-async (ssl) connections. WORKER_OVERCOMMIT should be a config option. - Don't count idle workers of not-accepting processes against MinSpareThreads, so that the parent will spawn new processes when necessary. - If we receive a keep-alive request while all workers are busy, don't block but close the connection immediately so that the client will re-connect to a different process. Related changes: - Log what is going on at trace loglevels. - Remove the bypass_push poll type flag, this code cannot be hit anymore (if it ever could?). - Add some macro helpers for dealing with timeout queues. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1137358 13f79535-47bb-0310-9956-ffa450edef68
