2011-09-14util_tdb: return -1/0 from lock_with_timeout functions.Rusty Russell1-2/+2
Keeps the tdb2 API change (which returns error codes, rather than -1) localized. The function returns -1 down the other path, so make it consistent. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-09-14dbwrap_tdb: handle tdb2 return values properly.Rusty Russell1-4/+4
TDB2 versions of tdb_parse_record etc return an error code, not -1. Turn those into -1/0 in dbwrap_tdb to insulate the rest of the code from that change. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-09-14tdb_compat: adapt to tdb2 API change.Rusty Russell1-3/+4

2011-08-29s3-lib: If we create a pipe socket, don't start to listen.Andreas Schneider1-6/+0
The create_pipe_sock() function should only create the socket as the name states and not start to listen on it too. We should start to listen on in the individual places as we need different backlog values.

2011-08-21s3-passdb: Keep caches coherentAndreas Schneider2-1/+16
When deleting a user send a message to all interested parties so they can purge their caches. Otherwise some processes may positively respond with a cached getpwnam, when the user have actully been removed. Without this some tests that remove and then immediately create users are flakey.

2011-08-21s3-id_cache: Use better names for id cache management opsAndreas Schneider2-14/+14
The IDMAP term is normally associated with Winbind's idmap stuff. These functions deal with id caching not id mapping. Signed-off-by: Simo Sorce <idra@samba.org>
2011-08-21s3-id_cache: Move id caches mgmt out of smbdAndreas Schneider2-0/+222
We must leave the MSG_IDMAP_KILL operation in SMBD as it uses smbd specific internal globals and makes sense only in the context of a smbd daemon. The rest is moved under lib/ as we need to deal with id cache cleanups in other daemons too (like lsasd). Signed-off-by: Simo Sorce <idra@samba.org>

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-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 Sorce2-7/+20
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 Sorce2-375/+21
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.

2011-08-11s3-messaging: Fix messaging classes.Simo Sorce1-8/+11
This has been broken since ff0ac5b0 (May 2007). Basically all messages were belonging to the General class except for CTDB messages. This fixed the message_send_all() function to correctly compute the class, and fixes registrations to include all they need to cope with the fact not all messages are of calss general (registrations rotted a bit because as long as FLAG_MSG_GENERAL was defined the process woould receive all messages).
