From 231d8719f1b6d8324882cde0eb136c045b7c8338 Mon Sep 17 00:00:00 2001 From: Jim Meyering Date: Sat, 4 Dec 2010 11:52:21 +0100 Subject: [PATCH] tests: make it harder to lose a race in spinlock-abuse * tests/misc/sort-spinlock-abuse: On a busy system, with only 12 pauses of length 0.1 seconds, the buggy (busy-spinlock blocked) sort would fail to accumulate 1 second of CPU time, and hence would mistakenly pass. Increase from 12 to 50. --- tests/misc/sort-spinlock-abuse | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/tests/misc/sort-spinlock-abuse b/tests/misc/sort-spinlock-abuse index 974e3d5..bbf5753 100755 --- a/tests/misc/sort-spinlock-abuse +++ b/tests/misc/sort-spinlock-abuse @@ -25,9 +25,9 @@ test "$(nproc)" = 1 && skip_ "requires a multi-core system" seq 100000 > in || framework_failure_ mkfifo fifo || framework_failure_ -# Arrange for sort to require 1.2+ seconds of wall-clock time, +# Arrange for sort to require 5.0+ seconds of wall-clock time, # while actually using far less than 1 second of CPU time. -(for i in $(seq 12); do read line; echo $i; sleep .1; done +(for i in $(seq 50); do read line; echo $i; sleep .1; done cat > /dev/null) < fifo & # Limit CPU time to 1 second -- 2.7.4
