Applied to the CVS tree. Note to Open POSIX Test Suite: Test 17-17.c was accidently left out of this patch, but the change is the same. - Robbie Robert V. Williamson <ro...@us...> Linux Test Project IBM Linux Technology Center Phone: (512) 838-9295 T/L: 678-9295 Fax: (512) 838-4603 Web: http://ltp.sourceforge.net IRC: #ltp on freenode.irc.net ==================== "Only two things are infinite, the universe and human stupidity, and I'm not sure about the former." -Albert Einstein Andreas Jaeger <aj...@su...> To: ltp...@li... Sent by: cc: ltp...@li...ur Subject: [LTP] Fix sigaction-07 testcases ceforge.net 04/29/2003 03:07 AM The testcase was non functional and non-portable: - Variables changed in signal handlers should use volatile sig_atomic_t - The timeout of child and parent should be different so that not both are awaked at the same time - The while loop exit condition was wrong I'm appending a patch, now the tests pass, Andreas ============================================================ Index: testcases/kernel/syscalls/sigaction/sigaction07.17-1.c --- testcases/kernel/syscalls/sigaction/sigaction07.17-1.c 14 Apr 2003 15:56:21 -0000 1.1 +++ testcases/kernel/syscalls/sigaction/sigaction07.17-1.c 29 Apr 2003 08:02:58 -0000 @@ -24,7 +24,7 @@ #include <errno.h> #include "posixtest.h" -int wakeup = 0;
