[Starlingx-discuss] python-eventlet upgrade issue

[Lin, Shuicheng]

Hi,
Anyone familiar with python-eventlet? I meet a problem when upgrade python-eventlet from "0.18.4-2" to "0.20.1-2", when do CentOS7.5 upgrade.
Eventlet will hook/patch some basic python function, such as "call"/"check_call" from subprocess.py
The issue is that, after upgrade to 0.20.1-2 version, these functions don't work as expected.

For the pass log (with eventlet 0.18.4), below log is as expected:
2018-08-28 05:38:33.816 21142 INFO sysinv.agent.pci [-] Could not determine DPDK support for NIC (vendor 0x8086 device: 0x100e), defaulting to False
But for the fail log(with eventlet 0.20.1), it seems the exception is not handled correctly:
2018-08-28 03:48:21.687 21302 ERROR sysinv.openstack.common.periodic_task [-] Error during AgentManager._agent_audit: Command '['query_pci_id', '-v 0x8086', '-d 0x100e']' returned non-zero exit status 1

Is there any code style change with new eventlet?
Thanks.
