* Fixed integer overflow with an excessively large amount of events.tobias2019-05-081-10/+15

* if there are no changes for kevent, pass in NULL instead.tedu2017-07-101-2/+2

* revert change to call kevent immediately.tedu2015-12-251-6/+65
| | | | | | | | | tcpbench (at a minimum) relies on the old behavior of changes all happening after all event handlers run. in particular, it resets the event for the listening socket *before* calling accept(), when it is still readable. kevent then (correctly) says it is readable on the next go through the loop. silly, subtle, and stupid. problem reported by kettenis
* change the kqueue backend to call kevent() as events are added insteadtedu2015-12-161-65/+6
| | | | | | | | | | | | of deferring until the dispatch loop. kqueue support for various types of files and filesystems has been historically incomplete, and kevent handles this condition by returning an error. the libevent dispatch loop has no way to recover from this error and fails catastrophically, bringing down the entire process because one file went bad. now, instead of all that happending, event_add will return an error. the application can choose to handle or ignore this error, but at least the band will play on. ok nicm

* r1.27 changed libevent to fire a read event when kqueue returned EBADFnicm2012-02-081-1/+2
| | | | | | | | | | | | | (and several other things, particularly EPIPE) on a file descriptor. This causes Google Chrome to die (probably due to a bug in Chrome but finding that is next to impossible at the moment). It's not really clear what libevent should when an invalid fd is added - the poll backend doesn't fire an event and select exits the event loop. Until this is settled, change kqueue to match poll and ignore EBADF, keeping the behaviour r1.27 fixed on EPIPE. Fix from robert@.
* Handle a wider range of kqueue error return values for an event,nicm2012-01-301-21/+40
| | | | | | | | prevents libevent exiting the event loop when getting EPIPE. Problem first seen by drahn@ and more recently hit by gilles@, fix based on one by Nick Mathewson. ok gilles
* Update to 1.4.14b.nicm2010-07-121-3/+7
| | | | | | | | | | | | | | From their change log: o Fix memory-leak of signal handler array with kqueue. [backport] o Make evutil_make_socket_nonblocking() leave any other flags alone. o Adjusted fcntl() retval comparison on evutil_make_socket_nonblocking(). o Re-add event_siglcb; some old code _was_ still using it. :( o Fix a free(NULL) in min_heap.h o Clean up properly when adding a signal handler fails. Also a local change to use an int rather than a long for fcntl(). ok guenther deraadt
* Update libevent to 1.4.13.nicm2010-04-211-68/+99
| | | | | | | | | | | | | This is the core library only, the DNS parts are removed and it does not include the other extra bits (HTTP, DNS, and RPC), a separate port for these will appear in due course. Thanks to jsg, sthen, alek, gilles, jacekm, bernd and any others I've forgotten for testing/comments. Note that /usr/include/evdns.h should be removed after updating. ok deraadt
