But all write() (reply from fops) happen without check, which can possibly lead to blocking indefinitely. all socket operations should happen with a poll() check for both write and read. all FILE * operations should be changed and should use the transport api's being added (tracked by #17354) which uses socket fd directly. the non-blocking write may involve implementing a write queue which is flushed after poll() indicates write-ready. Over clogging of the write-queue should be ensured by not read()ing from a socket which has N write-queue entries. (do not process requests from a socket which has not accepted the previous replies) _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/bugs/?func=detailitem&item_id=17355> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/
