Events: backout eventport changes (r5172) for now.

2013-04-16T12:58:03+00:00

Evenport method needs more work.  Changes in r5172, while being correct,
introduce various new regressions with current code.

Events: fixed typos in two previous commits.

2013-04-12T17:31:08+00:00

Events: handle only active events in eventport.

2013-04-12T15:04:23+00:00

We generate both read and write events if an error event was returned by
port_getn() without POLLIN/POLLOUT, but we should not try to handle inactive
events, they may even have no handler.

Events: protection from stale events in eventport and devpoll.

2013-04-12T15:02:33+00:00

Stale write event may happen if read and write events was reported both,
and processing of the read event closed descriptor.

In practice this might result in "sendfilev() failed (134: ..." or
"writev() failed (134: ..." errors when switching to next upstream server.

Events: fixed null pointer dereference with resolver and poll.

2013-01-25T09:59:28+00:00

A POLLERR signalled by poll() without POLLIN/POLLOUT, as seen on
Linux, would generate both read and write events, but there's no
write event handler for resolver events.  A fix is to only call
event handler of an active event.

Fixed compilation with -Wmissing-prototypes.

2012-07-24T15:09:54+00:00

Fixed spelling in multiline C comments.

2012-04-03T07:37:31+00:00

Copyright updated.

2012-01-18T15:07:43+00:00

Fixed AIO on Linux, broken in r4306.

2011-11-29T17:27:13+00:00

Events from eventfd do not have c->write set, and the stale event
check added in r4306 causes null pointer dereference.

Protection from stale write events in epoll.

2011-11-22T17:02:21+00:00

Stale write event may happen if epoll_wait() reported both read and write
events, and processing of the read event closed descriptor.
