[Kevin, Wang]

Hi,  experts

 

I am a programmer form China and I love the GNU parallel tool very much, It really a powerful tool and very cool, thanks for your contributions all the way to create this amazing tool!

 

I found a bug these days when I was using options like “halt soon, failed=1”in Ubuntu 16.04 LTS, below is some commands and outputs, could you help to check why does it not exit right now when one of the subprocess exit with non zero?

 

address@hidden:~/work# uname -a

Linux ubuntu 4.4.0-31-generic #50-Ubuntu SMP Wed Jul 13 00:07:12 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

address@hidden:~/work# cat /etc/issue

Ubuntu 16.04 LTS \n \l

 

address@hidden:~/work# parallel -j200% --halt now,fail=1 echo {}\; exit {} ::: 0 0 1 2 3;echo "exit code is :$?"

address@hidden:~/work# set -xeu -o pipefail && parallel -j200% --halt now,fail=1 echo {}\; exit {} ::: 0 0 1 2 3;echo "exit code is :$?"

+ parallel -j200% --halt now,fail=1 echo '{};' exit '{}' ::: 0 0 1 2 3
