[erlang-questions] run_erl.c question in R11B-4
Mon Apr 2 21:39:34 CEST 2007
I see that a SIGCHLD handler was added in run_erl.c in the R11B-4.
However the implementation of the signal handler function
(catch_sigchild) has nothing in the body.
I believe it should be:
--- ./erts/etc/unix/run_erl.c.orig 2006-11-22 10:57:35.000000000 -0500
+++ ./erts/etc/unix/run_erl.c 2007-04-02 15:23:45.000000000 -0400
@@ -676,6 +676,10 @@
static void catch_sigchild(int sig)
+ int stat;
+ status("Child terminated - exiting\n");
+ wait(&stat); /* Ensure that a child entry in the process table is
cleared, and release child's PID */
This way the death of the emulator will cause the death of run_erl.
Otherwise in presence of the -heart option it's possible to get in a
situation when run_erl is not properly restarted (*).
