From b4f7ccecd93ca9e64c3c3c774fdaefae83d7204a Mon Sep 17 00:00:00 2001 From: Peter Stephenson Date: Sun, 26 Oct 2014 17:47:42 +0000 Subject: 33531 with additions: retain status of exited background jobs. Add linked list of unwaited-for background jobs. Truncate at value of _SC_CHILD_MAX discarding oldest. Remove old lastpid_status mechanism for latest exited process only. Slightly tighten safety of permanently allocated linked lists so that this doesn't compromise signal handling. --- Src/signals.c | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) (limited to 'Src/signals.c') diff --git a/Src/signals.c b/Src/signals.c index 2df69f96e..e72850516 100644 --- a/Src/signals.c +++ b/Src/signals.c @@ -522,14 +522,14 @@ wait_for_processes(void) get_usage(); } /* - * Remember the status associated with $!, so we can - * wait for it even if it's exited.
