From d7a05d0728924b25c5ece7fa41f79fe4b073d92c Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Mon, 30 Jun 2014 20:05:34 +0100 Subject: [PATCH] test-skeleton: Kill any child process's offspring This makes sure any subprocesses created by the program being tested get killed as well if their parent times out. Otherwise if they are really stuck, they may remain there running forever after the test case and then the whole test suite has completed, until killed by hand. * test-skeleton.c (signal_handler): Kill the whole process group before killing the child individually. (main): Report any failure on `setpgid'. --- ChangeLog | 7 +++++++ test-skeleton.c | 9 +++++++-- 2 files changed, 14 insertions(+), 2 deletions(-) diff --git a/ChangeLog b/ChangeLog index 785baf996b..b2ea30c235 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,10 @@ +2014-06-30 Maciej W.
