Comment 2 Tim Speetjens 2014-10-24 07:40:45 UTC

When zsh (5.0.3, shipped with rhel7) is run with either
- a symlink named 'sh' pointing to zsh
- a symlink named 'ksh' pointing to zsh binary
- with the "-o POSIXJOBS" arguments (to set the POSIXJOBS option)

it runs correctly.

This means that the sh/ksh compatibility option runs correctly.

Also, as explained in http://www.zsh.org/mla/workers/2014/msg01280.html zsh-workers don't consider this as bug for zsh, running without POSIXJOBS option, as there are some more POSIX non-conformity issues remaining.

Therefor, closing not a bug.

Comment 3 Tim Speetjens 2014-10-24 07:45:36 UTC

However, testing with multiple pids, like:

sh -c "echo done1" &
pid1=$!
sh -c "echo done2" &
pid2=$!
sh -c "echo done3" &
pid3=$!
sleep 1
wait $pid1 $pid2 $pid3

still fails
$ zsh -o POSIXJOBS test-multi.sh 
done1
done2
done3
test-multi.sh:wait:9: pid 7203 is not a child of this shell
test-multi.sh:wait:9: pid 7204 is not a child of this shell
rc: 0
rc: 3

This seems to be fixed upstream:
