2010-10-01s3:events: Call all ready fd event handlers on each iteration of the main loopSteven Danneman1-1/+1
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)

2007-10-10r20931: This changes the notify infrastructure from a polling-based to an ↵Volker Lendecke1-5/+0
event-driven based approach. The only remaining hook into the backend is now void *(*notify_add)(TALLOC_CTX *mem_ctx, struct event_context *event_ctx, files_struct *fsp, uint32 *filter); (Should we put this through the VFS, so that others can more easily plug in?) The trick here is that the backend can pick filter bits that the main smbd should not handle anymore. Thanks to tridge for this idea. The backend can notify the main smbd process via void notify_fsp(files_struct *fsp, uint32 action, char *name); The core patch is not big, what makes this more than 1800 lines are the individual backends that are considerably changed but can be reviewed one by one. Based on this I'll continue with inotify now. Volker (This used to be commit 9cd6a8a82792b7b6967141565d043b6337836a5d)
2007-10-10r20846: Before this gets out of control...Volker Lendecke1-9/+8
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)
