The caller should take care of the global cli_state values.

Callers of tevent_req_done() (or similar functions) have to return directly.
Otherwise the callback could invalidate the current stack state,
which is likely to trigger segfaults.
If there was only one pending request and we just got the response
for that one, we can use tevent_req_done() directly.
Otherwise there're more pending requests and we need to call
cli_state_receive_next() or we got the response for chained requests.
Both means that we have to use tevent_req_defer_callback().
metze
It's up to the caller to notify the current request,
but we have to notify all other pending requests if
we're not able to read the next response from the server.
metze
If we got a problem on the connection we need to notify every
pending request. But we need to make use of tevent_req_defer_callback()
before tevent_req_nterror(), otherwise the callback, triggered
by tevent_req_nterror(), could invalidate the state of current caller,
which will likely cause segfaults.

smbd is not the only daemon interested in smb.conf changes. Move this
message to the GENERAL class so that all interested partied (nmbd,
winbindd, spoolssd, etc..) can receive this notification.

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).
Signed-off-by: Andreas Schneider <asn@samba.org>
The FLAG_MSG_PRINT_NOTIFY class is actually obsolete and never used, as the
only message belonging to it is not used either.

Be more correct in load printers at startup.
If async process have already started we do not need to force a reload, but we
just need to load the printers. If other process have not finished initializing
it makes no sense to try to force them as they are masking SIGHUP unitl init is
done anyway.

The background queue process is repsonsible for that.
Just reload printers if necessary or wait for a message from bq to do that.

The cups backend forks a child to do asynchronous work.
We need a sigchld handler in bq to properly wait for the chilod to finish and
reap it, otherwise it hangs the forever as a zombie process.

Children were not properly receiving messages to reload printers when
the background queue process was dispatching them.

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.
