2011-09-05s3-smbd: Rename reload_printers() and add documentation.Andreas Schneider1-1/+1
Autobuild-User: Andreas Schneider <asn@cryptomilk.org> Autobuild-Date: Mon Sep 5 17:59:47 CEST 2011 on sn-devel-104
2011-09-05s3-spoolssd: Remove stale printers only on a valid pcap update.Andreas Schneider1-2/+2
load_printers() removes stale printers and we should only remove them if we have a CUPS connection and talked to cups. Else we will remove every configured printer if cups is not available.

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-spoolssd: Send a message to the parent when we accept a connectionSimo Sorce1-0/+25
Every time we accept a connection wanr the parent, so it can run management routines and reallocate more resources if necessary. Signed-off-by: Andreas Schneider <asn@samba.org> Signed-off-by: Simo Sorce <idra@samba.org>
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: Fix worker flags handling.Simo Sorce1-1/+1
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 Sorce1-17/+3
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.

2011-08-21s3-spoolss: Introduce helper function to manage pool.Simo Sorce1-52/+64
We were not properly managing allowed clients and pool management was duplicated across a few callers. Concentrate all management heuristics in one single function. Signed-off-by: Andreas Schneider <asn@samba.org> Signed-off-by: Simo Sorce <idra@samba.org>

2011-08-11s3-messaging: Remove obsolete class.Simo Sorce1-2/+0
The FLAG_MSG_PRINT_NOTIFY class is actually obsolete and never used, as the only message belonging to it is not used either. Signed-off-by: Andreas Schneider <asn@samba.org>

2011-08-10s3-spoolss: do not call pcap_cache_reload() directlySimo Sorce1-5/+17
The background queue process is repsonsible for that. Just reload printers if necessary or wait for a message from bq to do that. Signed-off-by: Andreas Schneider <asn@samba.org>
2011-08-10s3-spoolss: Fix printers related messagingSimo Sorce1-4/+34
Children were not properly receiving messages to reload printers when the background queue process was dispatching them. Signed-off-by: Andreas Schneider <asn@samba.org>
2011-08-10s3-prefork: Fix use of child id.Simo Sorce1-10/+9
Children Ids must start at 1 as 0 represent the father. Also fix callbacks that restart logs to use a procedd global variable that holds the Id so that they work correctly both fot the parent process and the children. Signed-off-by: Andreas Schneider <asn@samba.org>
2011-08-10s3-printing: make sure to block SIGHUP ...Simo Sorce1-4/+20
... until we are ready to handle it. Also make us ready as early as possible in spoolssd. Signed-off-by: Andreas Schneider <asn@samba.org>
2011-08-10s3-spoolss: Use a global variable for the poolSimo Sorce1-60/+31
This allows for setting up signal handlers earlier which is needed for the following patch. It also simplify the code in a few places. After all we never have more than pool active at any time during spoolssd life span. Signed-off-by: Andreas Schneider <asn@samba.org>

2011-08-10s3-spoolssd: Use the child_id to open log filesSimo Sorce1-15/+43
This way each child has its own log file and avoid mixing all logs form all children in the same parent log file. Signed-off-by: Andreas Schneider <asn@samba.org>

2011-08-10s3-prefork: Set up a SIGCHLD handler by defaultSimo Sorce1-39/+14
We need to properly handle preforked children so it is better to just do that automatically. If the parent needs/wants to intercept SIGCHLD events it can set a callback that will be called by the prefork code once the internal cleanup function that checks all prefork children has been executed. Signed-off-by: Andreas Schneider <asn@samba.org>
2011-08-10s3:spoolssd Start spoolssd from printing_subsystem_initSimo Sorce1-17/+48

2011-08-10s3-prefork: Provide a cleanup functionSimo Sorce1-11/+4
This way the parent doesn't need to know how to handle dead children and keeps all of that within the prefork abstraction. Signed-off-by: Andreas Schneider <asn@samba.org>

2011-08-10s3-spoolssd: Use parametric option for prefork parametersSimo Sorce1-12/+48
example: spoolssd:prefork = 10:100:5 will configure spoolssd to start with a minimum of 10 preforked children, a max set to 100 children and spawns/retires 5 children at a time when ramping up/scaling down. Signed-off-by: Andreas Schneider <asn@samba.org>
2011-08-10s3-spoolss: make listening asynchronousSimo Sorce1-26/+60

2011-08-10s3-spoolssd: Use the prefork framework in spoolssdSimo Sorce1-3/+425
