2833	coreutils-8.10 sparse-to-pipe failure	Gilles Espinasse	lfs-book@…	"sparse-to-pipe test may fail when 
{{{
cat pipe > copy &
}}}
did not finish before
{{{
cmp sparse copy
}}}
This happen randomly to me with debian 2.6.26 kernel (x86 32 bits) but I haven't had a failure on 3 other machines with different kernels (even 2.6.27 or 2.6.18)

I don't know what is the key to reproduce the test failure.
I have two machines with mostly same CPU :

one with XP 3000+ and kernel 2.6.27 that never fail, 
one with XP 2800+ and kernel debian 2.6.26 that fail 80% of attempts.

Tested with
{{{
for i in {1..20}; do make -s check -C tests TESTS=cp/sparse-to-pipe 2>/dev/null;done | grep '1 test'
}}}

Upstream fix is to wait before cmp. A sed would be good enought to fix that
{{{
sed -i 's/^cmp sparse copy/wait; cmp sparse copy/' tests/cp/sparse-to-pipe
}}}

I let the milestone to 6.8 as the fix will be needed only for coreutils-8.10. I don't know why this happen on only one machine."	task	closed	normal		Book	SVN	normal	fixed
