2013-03-01tevent: the content of event is ignored by EPOLL_CTL_DELStefan Metzmacher1-2/+0

2013-03-01tevent: call epoll_panic() if EPOLL_CTL_DEL failedStefan Metzmacher1-4/+11
Only ENOENT is ignored as it is no error. Signed-off-by: Stefan Metzmacher <metze@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>

2013-03-01tevent: remove unused if (epoll_ev->epoll_fd == -1) return; checksStefan Metzmacher1-9/+0
We'll never leave epoll_check_reopen() with epoll_fd == -1. Signed-off-by: Stefan Metzmacher <metze@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>
2013-03-01tevent: avoid any operation on epoll_ev after a epoll_panic()Stefan Metzmacher1-11/+74
This calls TALLOC_FREE(ev->additional_data), which is epoll_ev within epoll_panic() before calling the fallback handler. In order to notice that a epoll_panic() happened, a caller can register a pointer to a bool variable under epoll_ev->panic_state. As epoll_check_reopen() can fail due to a epoll_panic(), we need to force the replay flag if we have called any event handler.

2013-03-01tevent: add epoll_{create,ctl}_panic_fallback() for testingStefan Metzmacher1-5/+49
This makes sure we only do random panics if a fallback handler is registered. Signed-off-by: Stefan Metzmacher <metze@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>

2013-02-14tevent: Add an internal function tevent_epoll_set_panic_fallback().Jeremy Allison1-0/+24
Can be set externally, allows us to fallback if epoll fails at runtime. Signed-off-by: Jeremy Allison <jra@samba.org> Reviewed-by: Stefan Metzmacher <metze@samba.org>
2013-02-14tevent: pass 'bool replay' to epoll_panic()Stefan Metzmacher1-5/+6
A fallback panic handler will need to know if there was an error while waiting for events (replay=true) or if the error happened on modify (replay=false). Signed-off-by: Stefan Metzmacher <metze@samba.org>
2013-02-14tevent: Ensure we return after every call to epoll_panic().Jeremy Allison1-0/+2
Currently we can't return from this, but the new fallback code will change this. Signed-off-by: Jeremy Allison <jra@samba.org> Reviewed-by: Stefan Metzmacher <metze@samba.org>
2012-06-08lib/tevent: Add trace point callbackMartin Schwenke1-0/+2
Set/get a single callback function to be invoked at various trace points. Define "before wait" and "after wait" trace points - more trace points can be added later if required. CTDB wants this to log long waits and events.

2011-08-11tevent: Set FD_CLOEXEC on epoll handleSumit Bose1-2/+17
If an application using libtevent starts a new process the epoll file descriptor is leaked to the new process if the event context is not freed explicitly. By setting FD_CLOEXEC this is not needed anymore. Signed-off-by: Simo Sorce <idra@samba.org>

these are not supposed to be exposed in the library
2009-03-17tevent: add support for immediate eventsStefan Metzmacher1-11/+17
They're like directly triggered timed events, but you can preallocated them and scheduling them will not fail. metze
2009-03-17tevent: add tevent_common_loop_wait() helper function and use itStefan Metzmacher1-17/+1
tevent_loop_wait should do the same for all backends. It should loop as long as we have pending events. metze
2009-03-17tevent: check signal events first in event_loop_onceStefan Metzmacher1-0/+5
We also check for signal events directly before and after the select/epoll calls. metze
2009-03-17tevent: let tevent_loop_once() just run one fd eventStefan Metzmacher1-15/+2
This makes the logic much simpler for the callers, and matches the samba3 behavior. If needed we can add performance tunning for tevent_loop_wait() later. metze

2009-01-03tevent: remove TEVENT_FD_AUTOCLOSE featureStefan Metzmacher1-3/+0
TEVENT_FD_AUTOCLOSE adds a dependency to SOCKET_WRAPPER, which is bad. Callers should use tevent_fd_set_close_fn() now. metze
