Hi!
----
Below is another testcase for ksh93's signal trap subsystem which
currently doesn't work:
-- snip --
set -o nounset
integer i
compound c=(
compound child=(
float sum=0.0
)
)
integer -r pid=$$
integer -r numprocs=256
trap '(( c.child.sum-=1.7 ))' USR1
trap '(( c.child.sum-=3.3 ))' USR2
trap '(( c.child.sum+=.sh.sig.status ))' CHLD
for (( i=0 ; i < numprocs ; i++ )) ; do
{
sleep $((numprocs / 64.))
kill -s USR1 ${pid}
kill -s USR2 ${pid}
exit 5
} &
done
float start=$SECONDS
while ! wait ; do
/usr/bin/true
if (( (SECONDS-start) > 20 )) ; then
print '# Aborting wait loop...'
break
fi
done
if (( c.child.sum == 0.0 )) ; then
printf '# success.\n'
exit 0
else
printf 'sum for all signals=%f (should be "0")\n' \
c.child.sum
exit 1
fi
# notreached
-- snip --
Expected output is '# success.' ... but ast-ksh.2013-05-24 currently
has more or less random values in c.child.sum, e.g. the output looks
like 'sum for all signals=1203.400000 (should be "0")'.

Bye,
Roland
