Before the fix, this +test waits a hard-coded amount of time in the parent process for the +child process to exit, and the child process may not be able to exit +soon enough. With this fix, the parent process in this test polls for +whether the SIGCHLD handler reaped the child process for at most 25 +seconds. + +Upstream-Status: Backport [commit ID: 75d974a] + +Signed-off-by: William Lyu <William.Lyu@windriver.com> +Signed-off-by: Randy MacLeod <randy.macleod@windriver.com> +Reported-by: Alexandre Belloni <alexandre.belloni@bootlin.com> + +Committer: William Lyu is now a Perl author. +--- + AUTHORS | 1 + + t/op/sigsystem.t | 17 ++++++++++++++--- + 2 files changed, 15 insertions(+), 3 deletions(-) + +diff --git a/AUTHORS b/AUTHORS +index 21948bfdc7..527dd992fd 100644 +--- a/AUTHORS ++++ b/AUTHORS +@@ -1443,6 +1443,7 @@ Wayne Scott <wscott@ichips.intel.com> + Wayne Thompson <Wayne.Thompson@Ebay.sun.com> + Wilfredo Sánchez <wsanchez@mit.edu> + William J.
