2007-10-10	r21212: detect if the kernel does not support integrated epoll/aio when the	Andrew Tridgell	1	-1/+11
	event context is created. This allows the LOCAL-EVENT test to pass on systems with have libaio but not the necessary kernel patches (This used to be commit 2ff8abf0022824e6ae93019ee1b3391e651a8ee7)
2007-10-10	r21171: fixed a bug related to recursive event handling.	Andrew Tridgell	1	-1/+1
	If this happens: - two sockets are readable, and select/epoll/aio returns both of them - read event on socket1 is called - inside that read event an event_loop_once is called, this returns that socket2 is readable - read event on socket2 is called - event_loop_once returns - top level event handler then calls read event on socket2 (as it still has that listed as readable) - read handler for socket2 returns zero byte read, which is interpreted as end of file - socket is incorrectly closed this happened with ctdb, but it could happen anywhere (just rarely). The fix is trivial - ensure we break out of the event loop when we have been called recursively. (This used to be commit e042002bb5ee8974220e1ade56b64389571f75a6)
2007-10-10	r20989: don't mark epoll as set until after the io_submit() succeeds	Andrew Tridgell	1	-1/+1
	this is part of the solution to LOCAL-EVENT on fort (This used to be commit 35f62bc12559e355d4ac73018afe255ea7c5866b)
2007-10-10	r20928: added signal events to lib/events	Andrew Tridgell	1	-0/+10
	Jeremy asked for this to allow Samba3 to use the Samba4 events library see torture/local/event.c for an example (This used to be commit 7e105482ff9a3da6b4708ff99a64f1881614fc5f)
2007-10-10	r20788: - remove epoll configure checks from libreplace	Stefan Metzmacher	1	-1/+1
	- fix epoll configure checks for the epoll and aio events backends - we should only activate the epoll backend if sys/epoll.h and epoll_create() are found - we should only activate the aio backend if sys/epoll.h, epoll_create(), libaio.h and io_getevents() are found hopefully fix the build on 'bnhtest' in the build farm... metze (This used to be commit d46a5efb03ea1df50567cad00e1589870cdb31fe)
2007-10-10	r20621: - enable the aio events backend on systems that support it	Andrew Tridgell	1	-3/+0
	- allow the events backend to be chosen in smb.conf (This used to be commit 4a8e07286f827a6f57b2c54d97d31172553ceb0d)
2007-10-10	r20539: - split the common timer related events code into events_timed.c	Andrew Tridgell	1	-138/+121
	- make it easier to plug in a new events backend - add simpler 'select' and 'epoll' backends This is part of the effort to add good AIO support. The events_aio.c backend is done, but sometimes dies with a SEGV, which is why it isn't enabled yet. (This used to be commit 934f18283dbc7958944931a93a854526bcd54884)
2007-10-10	r20104: this is a alternative events backend, which uses a hybrid of aio and	Andrew Tridgell	1	-0/+518
	epoll. It is not linked in anywhere yet - I'm committing it in case anyone else wants to have a look at it. The concept is quite strange really, but it seems to be the only way that Linux 2.6.x can currently use a unified event model allowing for AIO events and socket events to be waited for by a single unified event wait function. You setup a epoll system, then setup a weird aio event that points at the epoll system, then use io_getevents() to actually do the waiting. I'm hoping that kevents or a proper integration of epoll will allow us to avoid ths rather hackish scheme, but meanwhile this is the only path to proper AIO in Samba on Linux (without a horrible signals mess) (NOTE: this code requires some kernel patches to work at the moment) (This used to be commit 195051fdee341e8d8cb76e5c91dcc0f6c246a870)
