[OpenSIPS-Users] Will Opensip2 support epoll ET?

[dongwflj]

Hi Vlad:
Thanks for your answer, if use current open sips LT mode, you are right, because we del the fd from epoll every time once we get a trigger, but it is not efficient to move in and move out fd every time, so if I want to use ET mode and keep the tcp read socket in epoll, how about this case?

Hello,

The scenario you are describing is not possible because the TCP connection has attached to it the actual SIP msg that has been read so far. So if one worker receives EAGAIN, it will put the TCP connection back on the IN reactor, and when the FD will be triggered again, another worker will continue to read to the same SIP msg as the previous worker.

Hi:
I am learning opensip2, it seems currently no support for epoll ET, will we support it in future?
If we use ET, two TCP sip messages come to server, I think one worker thread should read all but till EAGAIN, but during the worker thread is reading, another new packet coming on the same connection, that will trigger another worker thread start to read buffer, will it cause the 2 worker thread read wrong data? How can we solve this kind of problem? Thanks!
