Subject: [PATCH] http: eliminate redundant bev fd manipulating and caching
|
||||
|
||||
At the very beginning we reset the bufferevent fd (if bev has it), which
|
||||
is not a good idea, since if user passes bufferevent with existing fd he
|
||||
has some intention.
|
||||
|
||||
So we need to:
|
||||
- use BEV_OPT_CLOSE_ON_FREE for default bufferevent_socket_new() (to
|
||||
avoid manual shutdown/closee)
|
||||
- drop getsockopt(SOL_SOCKET, SO_ERROR), since bufferevent already has
|
||||
evutil_socket_finished_connecting_()
|
||||
- drop supperior bufferevent_setfd(bev, -1) in
|
||||
evhttp_connection_connect_()
|
||||
|
||||
Closes: #795
|
||||
Refs: #875
