Update of bug #28652 (project lwip): Status: None => Need Info Assigned to: None => goldsimon _______________________________________________________ Follow-up Comment #1: Simply not pending on op_completed while do_recv is running might not do the trick for an embedded OS with static priorities. The solution favoured by me to implement this is to add a counter of received data to struct netconn or tcp_pcb and increase this counter instead of directly calling do_recv and then somehow letting the tcp-fasttimer handle the window updates. However, that would leave us either with threading problems (SYS_ARCH_PROTECT etc.) in the tcp-fasttimer or with yet another timer to handle window updates on netconn-level. Any other ideas? This additional task-switch while receiving socket data is so ugly and slow! _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/bugs/?28652> _______________________________________________ Nachricht geschickt von/durch Savannah http://savannah.nongnu.org/
