From d4172bde993275f26b62b53af85a5ac092846dad Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B6rn-Egil=20Dahlberg?= Date: Thu, 11 Oct 2012 16:38:04 +0200 Subject: erts: Change ERL_CRASH_DUMP_SECONDS behaviour Not setting ERL_CRASH_DUMP_SECONDS will now terminate beam immediately on a crash without writing a crash dump file. Setting ERL_CRASH_DUMP_SECONDS to 0 will also terminate beam immediately on a crash without writing a crash dump file, i.e. same as not setting ERL_CRASH_DUMP_SECONDS environment variable. Setting ERL_CRASH_DUMP_SECONDS to a negative value will let the beam wait indefinitely on the crash dump file being written. Setting ERL_CRASH_DUMP_SECONDS to a positive value will let the beam wait that many seconds on the crash dump file being written. A positive value will set both an alarm in beam AND a heart timeout for restart if heart is running. This is due to the change of 'heart' behavior when 'heart' is listening for a crash. --- erts/emulator/beam/sys.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'erts/emulator/beam/sys.h') diff --git a/erts/emulator/beam/sys.h b/erts/emulator/beam/sys.h index 2406c52f14..9dd8341520 100644 --- a/erts/emulator/beam/sys.h +++ b/erts/emulator/beam/sys.h @@ -652,7 +652,7 @@ void erts_sys_schedule_interrupt_timed(int set, erts_short_time_t msec); void erts_sys_main_thread(void); #endif -extern void erts_sys_prepare_crash_dump(void); +extern void erts_sys_prepare_crash_dump(int secs); extern void erts_sys_pre_init(void); extern void erl_sys_init(void); extern void erl_sys_args(int *argc, char **argv); -- cgit v1.2.3
