2011-08-15s3-prefork: Do not use mmap/mremap/munmap directlySimo Sorce1-9/+11
Use the wrappers in util.h as they deal with trying to do the best they can on platfroms that do not support mmap extensions. Autobuild-User: Simo Sorce <idra@samba.org> Autobuild-Date: Mon Aug 15 04:13:51 CEST 2011 on sn-devel-104
2011-08-10s3-prefork: Fix use of child id.Simo Sorce1-2/+2
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-prefork: Set up a SIGCHLD handler by defaultSimo Sorce1-3/+57
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.

2011-08-10s3-prefork: Provide a cleanup functionSimo Sorce1-9/+17
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-prefork: better timing out semanticsSimo Sorce1-4/+14
If this child has no clients, let the lock functions block for 1 second, and then immediately reschedule the operation. This means we catch the lock as soon as possible on a free child. If, instead, we are already serving a client, we want to be non blocking, so we timeout immediately on getting the lock, and then we sleep a 1/10th of a second. This means that a busy child will be slightly slower on picking up the lock, but we won't block the existing client from communicating with us as we immediately react to activity on the already opened file handler.

2011-08-10s3-prefork: add support for multiple listning file descriptorsSimo Sorce1-81/+66

2011-08-10s3-prefork: provide way to send a signal to all childrenSimo Sorce1-0/+14

2011-08-10s3-prefork: provide means to expand the pool sizeSimo Sorce1-0/+32

2011-08-10s3-prefork: add way to manage number of clients per childSimo Sorce1-2/+33
The allowed_clients var is a parent managed variable that tell children how many clients they are allowed to handle at the same time. This way children can overcommit but within parent controlled limits. Signed-off-by: Andreas Schneider <asn@samba.org>
2011-08-10s3-prefork: add asynchronous functionsSimo Sorce1-1/+259
To get a client connection it is now possible to use asynchronous functions. Signed-off-by: Andreas Schneider <asn@samba.org>
2011-08-10s3-prefork: implement prefork frameworkSimo Sorce1-0/+502
Primarily built for forked off rpc service daemons, but not tied to rpc services and generic enough to be used elsewhere easily. Signed-off-by: Andreas Schneider <asn@samba.org>
