2010-10-01s3:events: Call all ready fd event handlers on each iteration of the main loopSteven Danneman1-7/+15
Previously, only one fd handler was being called per main message loop in all smbd child processes. In the case where multiple fds are available for reading the fd corresponding to the event closest to the beginning of the event list would be run. Obviously this is arbitrary and could cause unfairness. Usually, the first event fd is the network socket, meaning heavy load of client requests can starve out other fd events such as oplock or notify upcalls from the kernel. In this patch, I have changed the behavior of run_events() to unset any fd that it has already called a handler function, as well as decrement the number of fds that were returned from select(). This allows the caller of run_events() to iterate it, until all available fds have been handled. I then changed the main loop in smbd child processes to iterate run_events(). This way, all available fds are handled on each wake of select, while still checking for timed or signalled events between each handler function call. I also added an explicit check for EINTR from select(), which previously was masked by the fact that run_events() would handle any signal event before the return code was checked. This required a signature change to run_events() but all other callers should have no change in their behavior. I also fixed a bug in run_events() where it could be called with a selrtn value of -1, doing unecessary looping through the fd_event list when no fds were available. Also, remove the temporary echo handler hack, as all fds should be treated fairly now.

This correctly initialises the event backend, and checks for errors (thanks to Metze for suggesting this)

2010-02-05s3-events: make the old timed events compatible with teventAndrew Tridgell1-2/+19
tevent ensures that a timed event is only called once. The old events code relied on the called handler removing the event itself. If the handler removed the event after calling a function which invoked the event loop then the timed event could loop forever. This change makes the two timed event systems more compatible, by allowing the handler to free the te if it wants to, but ensuring it is off the linked list of events before the handler is called, and ensuring it is freed even if the handler doesn't free it.

2009-01-28Avoid valgrind errorsVolker Lendecke1-35/+13
In event handlers, we might destroy other events that are pending in the lists. We can only run one event safely per select call. Yes, I've seen these valgrind errors :-) Jeremy, with ccdd921e61 you had checked in the change to run multiple events. Do you remember why it was necessary and could not be solved in a different way?

For some bugs I really wonder how they can go undetected for so long. Fix a bug reported by Mathias Dietz. No samba bugzilla entry, but still 100% needed for 3-2-stable.

2008-04-14Enable multiple fd events on a single file descriptorVolker Lendecke1-1/+1
Now we can have multiple events listen on a single fd. The order in which they are called is naturally not defined, meaning that it is only deterministic if exactly one event is readable or writeable. (This used to be commit 61503f822b60f98dd1f7549707ec89b48e32caeb)

This add a struct event_context and infrastructure for fd events to smbd. This is step zero to import lib/events. Jeremy, I rely on you to watch the change in receive_message_or_smb() closely. For the normal code path this should be the only relevant change. The rest is either not yet used or is cosmetic. Volker (This used to be commit cd07f93a8aecb24c056e33b1ad3447a41959810f)
