Posted by Suteng <su...@huawei.com>.
In libprocess libevent.cpp, is avoid to using epoll. These is the code:
/home/suteng/code/mesos/3rdparty/libprocess/src/libevent.cpp
206 // TODO(jmlvanre): Allow support for 'epoll' once SSL related
207 // issues are resolved.
208 struct event_config* config = event_config_new();
209 event_config_avoid_method(config, "epoll");

主题: Re: libprocess libevent backend
Which issue are you referring to?
Libprocess uses libev by default, with --enable-libevent as a configure option to use libevent instead. Both of these backends should use epoll if the system has it available. Are you seeing otherwise?
