[Doubt] Updating epoll interest list Upon EAGAIN/EWOULDBLOCK while sending

[PrashanthaTP]

Inside HandleEpollEvent function, Upon EPOLLOUT, if EAGAIN/EWOULDBLOCK occurs, the client fd is being readded to epoll list, but shouldn't it be just modified as done while doing recv?

EPOLLOUT https://github.com/trungams/http-server/blob/1c171367234d245fa9a5452c86354681bbfe383c/src/http_server.cc#L206-L207

EPOLLIN https://github.com/trungams/http-server/blob/1c171367234d245fa9a5452c86354681bbfe383c/src/http_server.cc#L180-L183

Also is it required to do this? or can we just skip this part without doing any modification to interest list and retry when EAGAIN/EWOULDBLOCK happens?

Thanks in advance,
