beanstalkd 1.5 and centos 5.7 EPOLLRDHUP

[Thomas Parrott]

Hi,

There is a problem compiling beanstalkd 1.5 on centos 5.7. CentOS
seems to be missing EPOLLRDHUP feature.

Can we optionally use libevent, as that worked fine?

Wow, what kernel does Centos 5.7 use? According to man epoll_ctl,
EPOLLRDHUP was introduced in kernel 2.6.17, which was released
over five years ago. I think that's old enough to be called "ancient".

Maybe I can find a workaround and avoid using that flag entirely.
Patches are welcome!

Sorry, libevent is not an option any more. Beanstalkd as a whole
is actually much simpler now without it. We got better portability
from libevent combined with autotools, but in the end that wasn't
worth the hassle.
