Hey all,
Yesterday morning I decided to update the freebsd port for
libevent to 1.2 and send in a pr. Someone previously had bumped it up to
the 1.2 preview release that Niels had kindly let us play with.
Anyways.. afterwards I had the motivation to go work on a side project
of mine that uses libevent. Well it started failing with the new
install. I've stripped down a simple case that uses timers (which
triggers the problem), from a larger program (attached). Can I get
others to try this out and see if they get invalid similar to this?
export -n NOKQUEUE
~/test> ./test-failure
[warn] kevent: Invalid argument
~/test> export EVENT_NOKQUEUE=1
~/test> ./test-failure
[warn] poll: Invalid argument
~/test> export EVENT_NOPOLL=1
~/test> ./test-failure
[warn] select: Invalid argument
Thanks..
-Phil.
