Ansible pipelining breaks with tlog #349
Comments

Hi, Thanks for reporting this issue and providing the simple reproducer. We tried to fix this problem already in RHEL, we validated the fix was working in RHEL/Fedora environments. I need to investigate further what is different in your environment compared to the RHEL environment for the ansible |

Hi !
I've encountered an issue with Ansible in combination with Tlog on multiple Ubuntu 20.04 hosts. We need to delegate some tasks in several playbooks to other hosts. If the option
pipelining=Trueis set and we try to perform a task with thedelegate_tooption on a host, which uses thetlog-rec-sessionshell, the task will fail. If we set the optionpipelining=Falsethe task will proceed as expected.The behavior in relation to the pipelining option will also only happen, when the task get performed via
delegate_to.If the same task, get's processed without
delegate_to, but on the same host and the optionpipelining=True, everything will proceed as expected.We manage the server with Ansible version 2.12.7 and option
pipelining=TrueThe Playbook for testing is the following:
To test and reproduce the issue we have set up two hosts with Tlog
v12.1, which has been build from the master branch.The playbook will then get started as the following:
The error message is the following:
When setting
pipeliningtoFalse, the playbook will proceed as expected.The text was updated successfully, but these errors were encountered:
