Hi!
----
While testing the signal issues we stumbled over an issue with the
"wait" builtin - it seems doing a $ while ! wait ; do true ; done #
(the loop is neccesary since "wait" can be interupted by signals)
doesn't wait for all child processes launched by the shell.
The following testcase...
-- snip --
$ cat ksh_waitjobs1.sh
typeset -i i
for (( i=0 ; i < 256 ; i++ )) ; do
{
sleep 10
exit 0
} &
done
while ! wait ; do
true
done
jl="$(LC_ALL='C' jobs -l | fgrep Running)"
if [[ "$jl" == '' ]] ; then
printf '# success.\n'
exit 0
else
printf '# error: job list not empty:\n%s\n' "$jl"
exit 1
fi
# notreached
-- snip --
... works flawlessly with bash4 (bash 4.2.42(1)) on SuSE 12.3/AMD64/64bit:
-- snip --
$ bash ksh_waitjobs1.sh
# success.
-- snip --
... but the same script fails with ast-ksh.2013-05-24:
-- snip --
$ ~/bin/ksh ksh_waitjobs1.sh
# error: job list not empty:
[256] + 8094 Running <command unknown>

[4] 7842 Running <command unknown>
[3] 7841 Running <command unknown>
[2] 7840 Running <command unknown>
[1] 7839 Running <command unknown>
-- snip --
Uhm... is this a bug or am I doing something wrong ?

Bye,
