From b990279304b5e2b2ee0f64480cb09eda33f76beb Mon Sep 17 00:00:00 2001 From: Ira Cooper Date: Wed, 14 Mar 2012 12:56:02 -0400 Subject: util: Add --disable-fault-handling. On some platforms you can not debug coredumps after the default signal handler gets done dumping core. This allows waf to have an option to disable our default signal handler. --- lib/util/fault.c | 2 ++ lib/util/wscript | 3 +++ lib/util/wscript_configure | 3 +++ 3 files changed, 8 insertions(+) create mode 100644 lib/util/wscript (limited to 'lib') diff --git a/lib/util/fault.c b/lib/util/fault.c index 7fe081d285..b3527bb22e 100644 --- a/lib/util/fault.c +++ b/lib/util/fault.c @@ -96,6 +96,7 @@ void fault_setup(void) if (fault_state.disabled) { return; } +#if !defined(HAVE_DISABLE_FAULT_HANDLING) #ifdef SIGSEGV CatchSignal(SIGSEGV, sig_fault); #endif @@ -105,6 +106,7 @@ void fault_setup(void) #ifdef SIGABRT CatchSignal(SIGABRT, sig_fault); #endif +#endif } _PUBLIC_ const char *panic_action = NULL; diff --git a/lib/util/wscript b/lib/util/wscript new file mode 100644 index 0000000000..d296e7565b --- /dev/null +++ b/lib/util/wscript @@ -0,0 +1,3 @@ +def set_options(opt): + ''' This is a bit strange, but disable is the flag, not enable.
