Ansible lost tmp dir when run script module

[Andy]

Hi experts,

     In our test environment, some test cases will failed due to ansible run script moudle, this is hard to reproduce, so I write a script to reproduce this issue, below is the detail a bout this bug:

# or with command line flags. ansible will read ANSIBLE_CONFIG,
# ansible.cfg in the current working directory, .ansible.cfg in

# finds first

# command module appear to be simplified by using a default Ansible module
# instead.  These warnings can be silenced by adjusting the following

# Example:
# control_path = %(directory)s/%%h-%%r
#control_path = %(directory)s/ansible-ssh-%%h-%%p-%%r

SUMMARY

I have a test script which will re-run a task on the host(localhost), but after a lot of times(sometimes only a few minutes) re-run the task, the task failed by report:

STEPS TO REPRODUCE

Only need to replace your real host ip and run the test_script.py will re-produce the bug.
BTW, don't forget to add your host ip to /etc/ansible/hosts

EXPECTED RESULTS

Tasks can run normally all the time.

ACTUAL RESULTS

After repeat the task, task will failed by lost the tmp dir.

[Andy]

This issue seems not only a script module issue, after I re-run the test script, setup module also meet the same problem:

After debug this issue, I find it fails in function _make_tmp_path of file /usr/lib/python2.7/site-packages/ansible/runner/__init__.py

below is the debug output:

Does this means the ssh connection broken? This is strange due to I run this task on localhost, so network issue should not happen.

Maybe I missed it in your first mail (which was very detailed, hats
off for the effort), but where did you specify 'connection: local'? If
you did not, then you would connect to your localhost (or its IP) via ssh.

The host ip I specify in yaml file is my local host ip address.

Then you are connecting via ssh...

Try adding "connection: local" to your playbook.

yes, you are right, after add 'connection: local' to my playbook, this issue seems gone away, but I still want to know how to avoid this issue when I didn't run the task for local host.

With the information you have now (works with connection: local, fails
via ssh) I would say open a bug report/issue on github.

Oh, and try setting this in ansible.cfg:

[ssh_connection]
control_path = %(directory)s/%%C

I had lots of issues with the control_path being to long before
setting this...

Thanks, Johannes , I have reported this issue on github, BTW, ansible didn't recognize the config: %C

It is sometimes useful to re-run the command using -vvvv, which prints SSH debug output to help diagnose the issue.

There should be two %% before the C...
