Data Fields | |
| struct comm_point * | cp |
| the TCP comm point for this. | |
| struct sldns_buffer * | spool_buffer |
| the buffer to use to spool reply from mesh into, it can then be copied to the result list and written. | |
| int | in_worker_handle |
| are we in worker_handle function call (for recursion callback) | |
| int | is_drop |
| is the comm point dropped (by worker handle). | |
| int | is_reply |
| is the comm point set to send_reply (by mesh new client in worker handle), if so answer is available in c.buffer | |
| int | read_is_closed |
| read channel has closed, just write pending results | |
| int | read_again |
| read again | |
| int | num_open_req |
| number of outstanding requests | |
| struct tcp_req_open_item * | open_req_list |
| list of outstanding requests | |
| int | num_done_req |
| number of pending writeable results | |
| struct tcp_req_done_item * | done_req_list |
| list of pending writable result packets, malloced one at a time | |
| struct comm_timer * | read_again_timer |
| the read again timer, when the number of pipelined TCP queries is large, it waits, zero time, for a new event loop to service the remainder of the TCP traffic on the fd. | |
TCP request info.
List of requests outstanding on the channel, that are asked for but not yet answered back.
| struct comm_point* tcp_req_info::cp |

| struct sldns_buffer* tcp_req_info::spool_buffer |
the buffer to use to spool reply from mesh into, it can then be copied to the result list and written.

| int tcp_req_info::is_drop |
is the comm point dropped (by worker handle).
That means we have to disconnect the channel.
