Hello,

In general the whole LTP test cases are running in the background , connected to the caller script (ltp.sh) via a pipe. how to run it properly?

I'm not sure what you mean by that. In the test definition we use it's ltp.sh is called in the foreground: https://github.com/Linaro/test-definitions/blob/master/automated/linux/ltp/l... It will print all output from LTP as it comes. Example here: https://lkft.validation.linaro.org/scheduler/job/1017325#L1770

Hello,

are you running a process in the background? Looks like the shell is just not returning which happen when a process is still running in the background.

Hi!

Have some issues with recognition of ltp test end point. After receiving message of the ltp's execution finish, job is still running and waiting with line :

Listened to connection for namespace 'tlxc' done

until get timeout.

Also sometimes job runs good without that stuck. All scripts to run ltp were taken from lava's repo, without any changes. Just edit skipfile

Here is end of log with stuck ltp https://pastebin.com/1qJAbxTJ

Here is end of log with successful ltp recognition. https://pastebin.com/BnFyq5dU

Here is test part of the job. https://pastebin.com/m6vAWkZ9

Ah, I get it now. What you can do to debug is completely remove the whole pipe redirection code. It's there so we can return the exit code from runltp and still pipe the output to the log file. Removing it will result in potential false exit code but for debugging should be OK. This way you can rule out this part of the script as a culprit. If the job still hangs, the problem comes from ltp itself (your output suggests it's not the case). The concept for the pipe0 comes from here: https://unix.stackexchange.com/a/70675.
