Category: None Group: None Status: Open >Resolution: Fixed Priority: 1 Private: No Submitted By: megurikuru (megurikuru) >Assigned to: renzo davoli (rd235) Summary: Cannot profile application with unmanaged SIGTERM Initial Comment: Virtual NetManager (VNM) works together with VDE. When VNM stops running sub-programs (wirefilter, vde_switch, etc) sends SIGTERM (15). Inside VDE elements, at present, the default action with SIGTERM is to do a cleanup() , reattach the default signal management and execute default management of SIGTERM, that is SIGKILL. When profiling programs compiled with -gp, a clean exit is needed to correctly write the profiling information file (gmon.out). That means the program has to do a return from the main or execute exit(int); I've fixed this doing a "if(sig==SIGTERM) exit(0);" inside the sig_handler function of the various programs (vde_switch,wirefilter,etc), just before the "kill(getpid(), sig);" line. ---------------------------------------------------------------------- >Comment By: renzo davoli (rd235) Date: 2011-02-14 15:38 Message: current svn includes a fix for all the commands. ---------------------------------------------------------------------- Comment By: megurikuru (megurikuru) Date: 2010-11-22 20:47 Message: Errata corrige: the line "if(sig==SIGTERM) exit(0);" has to be inserted at the head of sig_handler function to avoid double cleanup call [this is because the use of atexit(cleanup); function in main]. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=611248&aid=3115854&group_id=95403 ------------------------------------------------------------------------------ The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE: Pinpoint memory and threading errors before they happen.
