Potential Regression Preventing Arista EOS Connections

SUMMARY

Potential Regression Preventing Arista EOS Connections

ISSUE TYPE

• Bug Report

COMPONENT NAME

on_open_shell() in TerminalModule of arista.eos

ANSIBLE VERSION

ansible [core 2.13.1]
  config file = None
  configured module search path = ['/home/jmorgan/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /home/jmorgan/.local/lib/python3.8/site-packages/ansible
  ansible collection location = /home/jmorgan/.ansible/collections:/usr/share/ansible/collections
  executable location = /home/jmorgan/.local/bin/ansible
  python version = 3.8.10 (default, Mar 15 2022, 12:22:08) [GCC 9.4.0]
  jinja version = 3.1.2
  libyaml = True

COLLECTION VERSION

# /home/jmorgan/.local/lib/python3.8/site-packages/ansible_collections
Collection Version
---------- -------
arista.eos 5.0.1

# /home/jmorgan/.ansible/collections/ansible_collections
Collection Version
---------- -------
arista.eos 5.0.0

CONFIGURATION

config dump command returned nothing.

OS / ENVIRONMENT

Linux 5.10.16.3-microsoft-standard-WSL2 #1 SMP Fri Apr 2 22:23:49 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

STEPS TO REPRODUCE

Minimal test case is fairly straightforward- inventory file is just setting ansible_user and ansible_password for a single arista switch

---
- hosts: all
  connection: network_cli
  gather_facts: no
  vars:
    ansible_network_os: eos
  tasks:
    - name: Gather info from Show Version
      arista.eos.eos_config:
        commands: 'show version'
      no_log: false

EXPECTED RESULTS

I'd expect it to successfully return the arista EOS version.

ACTUAL RESULTS

The command returns with a failure that the terminal parameters cannot be set. This appears to have originally surfaced back in 2018, but the fix doesn't appear in the main branch- not sure if it was intentionally removed or what: https://github.com/ansible/ansible/issues/45627

A colleague pointed out that this particular Arista is old enough that it does not support the width parameter- I'm not sure how crucial that is to the plugins functionality.
