From 924b9229717b749e303f3fb161616bebf53b5cdc Mon Sep 17 00:00:00 2001 From: ajs Date: Sat, 16 Apr 2005 17:11:24 +0000 Subject: 2005-04-16 Andrew J. Schorr * configure.ac: Added AC_ARG_ENABLE(time-check). By default, warning messages will now be printed for threads or commands that take longer than 5 seconds, but this configure argument can be used to disable the checks or change the threshold. * thread.h (thread_consumed_time): Declare new function to calculate elapsed microseconds. * thread.c (thread_consumed_time): Must be global not static so we can call it from lib/vty.c:vty_command. (thread_should_yield): Surround with `#if 0' to make clear that this function is not currently being used anywhere. (thread_call): If CONSUMED_TIME_CHECK is defined, print a CPU HOG warning message if the thread takes more than CONSUMED_TIME_CHECK microseconds. * vty.c (vty_command): If CONSUMED_TIME_CHECK is defined, print a CPU HOG warning message if the command takes more than CONSUMED_TIME_CHECK microseconds. --- configure.ac | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) (limited to 'configure.ac') diff --git a/configure.ac b/configure.ac index 08b5214f..cbc95212 100755 --- a/configure.ac +++ b/configure.ac @@ -5,7 +5,7 @@ ## Copyright (c) 1996, 97, 98, 99, 2000 Kunihiro Ishiguro ## Portions Copyright (c) 2003 Paul Jakma ## -## $Id: configure.ac,v 1.103 2005/04/16 15:38:23 paul Exp $ +## $Id: configure.ac,v 1.104 2005/04/16 17:11:24 ajs Exp $ AC_PREREQ(2.53) AC_INIT(Quagga, 0.99.0, [http://bugzilla.quagga.net]) @@ -195,6 +195,8 @@ AC_ARG_ENABLE(gcc_ultra_verbose, [ --enable-gcc-ultra-verbose enable ultra verbose GCC warnings]) AC_ARG_ENABLE(gcc-rdynamic, [ --enable-gcc-rdynamic enable gcc linking with -rdynamic for better backtraces]) +AC_ARG_ENABLE(time-check, +[ --disable-time-check disable slow thread warning messages]) if test x"${enable_gcc_ultra_verbose}" = x"yes" ; then CFLAGS="${CFLAGS} -W -Wcast-qual -Wstrict-prototypes" @@ -207,6 +209,14 @@ if test x"${enable_gcc_rdynamic}" = x"yes" ; then LDFLAGS="${LDFLAGS} -rdynamic" fi +if test x"${enable_time_check}" != x"no" ; then + if test x"${enable_time_check}" = x"yes" -o x"${enable_time_check}" = x ; then + AC_DEFINE(CONSUMED_TIME_CHECK,5000000,Consumed Time Check) + else + AC_DEFINE_UNQUOTED(CONSUMED_TIME_CHECK,$enable_time_check,Consumed Time Check) + fi +fi + if test "${enable_broken_aliases}" = "yes"; then if test "${enable_netlink}" = "yes" then -- cgit v1.2.1
