Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: megurikuru (megurikuru) Assigned to: Nobody/Anonymous (nobody) 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: megurikuru (megurikuru) Date: 2010-11-22 21:47 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 ------------------------------------------------------------------------------ Increase Visibility of Your 3D Game App & Earn a Chance To Win $500!
