Remove client if an error occurs at recv/send

[u413-284-si]

use shallCloseConnection boolean

based on eval

[gwolf-011235]

use shallCloseConnection boolean

Why?

If recv errors with -1 we close fd and set connection status closed:

• connectionReceiveHeader() Server.cpp:752
• connectionReceiveBody() Server.cpp:862

If send errors with -1 we close fd and set connection status closed:

• connectionSendResponse() Server.cpp:972

We could additionally remove the event from epoll, although this should happen automatically.

From man epoll: Will closing a file descriptor cause it to be removed from all epoll interest lists? Yes, but be aware of the following point. [~= if you have two refrences it won't be removed]

[u413-284-si]

Yes, you are right, this point is already handled. Was not fully aware of the closing of fds when an error occurs with recv/send when I was cross-checking the eval sheet. This can be closed, all the better!
