Nope, without the patch we only see case00 completing and the test exits while in the middle of case01 # ./ppoll01 ppoll01 0 TINFO : (case00) START EXPECT: return value(ret)=(N >= 0) errno=0 (Success) RESULT: return value(ret)= 1 errno=0 (Success) ppoll01 0 TINFO : (case00) END => OK ppoll01 0 TINFO : (case01) START # With the patch we see the output as follows... # ./ppoll01 ppoll01 0 TINFO : (case00) START EXPECT: return value(ret)=(N >= 0) errno=0 (Success) RESULT: return value(ret)= 1 errno=0 (Success) ppoll01 0 TINFO : (case00) END => OK ppoll01 0 TINFO : (case01) START EXPECT: return value(ret)=(N >= 0) errno=0 (Success) RESULT: return value(ret)= 0 errno=0 (Success) ppoll01 0 TINFO : (case01) END => OK ppoll01 0 TINFO : (case02) START EXPECT: return value(ret)=(N >= 0) errno=0 (Success) RESULT: return value(ret)= 0 errno=0 (Success) ppoll01 0 TINFO : (case02) END => OK ppoll01 0 TINFO : (case03) START EXPECT: return value(ret)=(N >= 0) errno=0 (Success) RESULT: return value(ret)= 1 errno=0 (Success) ppoll01 0 TINFO : (case03) END => OK ppoll01 0 TINFO : (case04) START EXPECT: return value(ret)=-1 errno=4 (Interrupted system call) RESULT: return value(ret)=-1 errno=4 (Interrupted system call) ppoll01 0 TINFO : (case04) END => OK ppoll01 0 TINFO : (case05) START EXPECT: return value(ret)=-1 errno=4 (Interrupted system call) RESULT: return value(ret)=-1 errno=4 (Interrupted system call) ppoll01 0 TINFO : (case05) END => OK ppoll01 0 TINFO : (case06) START EXPECT: return value(ret)=-1 errno=22 (Invalid argument) RESULT: return value(ret)=-1 errno=22 (Invalid argument) ppoll01 0 TINFO : (case06) END => OK ppoll01 0 TINFO : (case07) START EXPECT: return value(ret)=-1 errno=14 (Bad address) RESULT: return value(ret)=-1 errno=14 (Bad address) ppoll01 0 TINFO : (case07) END => OK ppoll01 1 TPASS : ppoll01 call succeeded # ------------------------------------------------------------------------------ Come build with us!
