2011-08-21s3-spoolss: Remove useless checkSimo Sorce1-24/+4
If we *really* are a bout to exit (PF_WORKER_EXITING) then the event will not be called as the loop will exit. Otherwise PF_SRV_MSG_EXIT may not be honoured for a long time if we have cients connected, therefore keep handling SIGHUP properly in those cases.

2011-08-21s3-prefork: Fix code to retire childrenSimo Sorce3-11/+16
We have to be more careful when retiring children. We cannot stop accepting connections as soon as the server tells us to quit because if max_children is reached and we still have clients connected, the server will not be able to spawn new children until one exits. And children will not exit until all the clients closed the connections. So we keep operating past our recall until we have 0 connections. Also do not try to recall children that still have >= 1 clients connected, they couldn't anyway. Also use messaging to warn children and not SIGHUP.

2011-08-21s3-spoolssd: User new prefork helpers to simplify code.Simo Sorce1-27/+3
Also stop using the listening as now the prefork code properly sets the PF_WORKER_ACCEPTING flag and it can be relied upon without having to keep additional status around. Signed-off-by: Andreas Schneider <asn@samba.org> Signed-off-by: Simo Sorce <idra@samba.org>
2011-08-21s3-prefork: add a few more utility functionsSimo Sorce2-0/+26
Add a few util functions children side so that daemons do not have to care about properly setting num_clients and state. Let a common helper do it so that they are all consistent. Signed-off-by: Andreas Schneider <asn@samba.org> Signed-off-by: Simo Sorce <idra@samba.org>
2011-08-21s3-prefrok: Handle only valid childrenSimo Sorce1-4/+19
Children that are about to exit shouldn't be counted as a source of connections, and also makes no sense to chenge their allowances if they are about to exit. Also children with negative num_clients are faulty, exclude them as well. Signed-off-by: Andreas Schneider <asn@samba.org> Signed-off-by: Simo Sorce <idra@samba.org>
2011-08-21s3-prefork: Fix worker flags handling.Simo Sorce4-9/+22
We can't have a clear idea of wether the worker is IDLE or BUSY. The only things we can tell is if it is Alive, whether it is currently Accepting connections or wether it is Exiting soon. Remove PF_WORKER_IDLE, PF_WORKER_BUSY and replace their use with PF_WORKER_ALIVE. Also properly assign PF_WORKER_ACCEPTING so that users of the API can rely on the flag.

2011-08-21s3-prefork: do not use a lock_fd, just race on accept()Simo Sorce4-410/+29
We used a lock mimicking what apache does for preforked children. But it doesn't work properly in our case because we do not stop once a request has been served. Clients are allowed to perform multiple requests and keep the connection open. This means that if we allow multiple clients per children, then a child could take the lock and then be asked to do a long or even locking operation by a client it already is serving. This woulkd cause the whole server to deadlock, as the child is now busy and also holding on the lock. Using a race on accept() by having a tevent_fd on the listening socket wait for read events we never deadlock. At most we cause a bit of contention among children. But in the generic case connections are much less frequent for us as clients tend to be long lived. So the little contention we may have is not a big deal.
