Hi! When tst-pselect.c fails (quite often when running on kernel that doesn't have pselect6 syscall, because pselect is then not atomic, but even 2.6.18 x86_64 kernel it fails rather quickly with pselect6 syscall when running while misc/tst-pselect; do :; done), test-skeleton.c only kills its immediate child, while the other child sticks around forever. The following patch is one possibility to avoid this: 2006-12-14 Jakub Jelinek <jakub@redhat.com> * misc/tst-pselect.c (do_test): Break the child loop if parent was killed by timeout handler. --- libc/misc/tst-pselect.c.jj 2006-09-18 09:11:59.000000000 +0200 +++ libc/misc/tst-pselect.c 2006-12-14 16:35:33.000000000 +0100 @@ -61,12 +61,15 @@ do_test (void) FD_SET (fds[0][0], &rfds); int e; + /* Break the loop if our parent is killed by test-skeleton.c's + timeout handler. */ + pid_t ppid = getppid (); do { errno = 0; e = pselect (fds[0][0] + 1, &rfds, NULL, NULL, &to, &ss); } - while (e == 0); + while (e == 0 && getppid () == ppid); if (e != -1) { Jakub
