URL: <http://savannah.nongnu.org/task/?14395> Summary: recv of short buffer should eventually time out Project: lwIP - A Lightweight TCP/IP stack Submitted by: goldsimon Submitted on: Thu 02 Mar 2017 12:55:10 PM UTC Category: socket/netconn Should Start On: Thu 02 Mar 2017 12:00:00 AM UTC Should be Finished on: Thu 02 Mar 2017 12:00:00 AM UTC Priority: 3 - Low Status: None Privacy: Public Percent Complete: 0% Assigned to: None Open/Closed: Open Discussion Lock: Any Planned Release: None Effort: 0.00 _______________________________________________________ Details: When recv(1024) is called but we only have 1022 bytes, we currently wait forever (unless the PSH bit is set or the netconn is nonblocking/has a timeout set). It seems like other platforms time out in this case and return 1022. --> check how linux/windows/xBSD behave? _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/task/?14395> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/
