Description Bob Fournier 2018-02-07 14:57:36 UTC
Description of problem:

Version 2.8.22 of construct has introduced a change to the core exception handling. The FieldError exception is no longer supported. As ironic-inspector was handling this exception explicitly it results in the following ironic-inspector test failures.


Captured traceback:
    Traceback (most recent call last):
      File "/home/bfournie/workspace/ironic-inspector/.tox/py3/lib/python2.7/site-packages/mock/mock.py", line 1305, in patched
        return func(*args, **keywargs)

      File "ironic_inspector/plugins/lldp_basic.py", line 56, in _parse_lldp_tlvs
        if parser.parse_tlv(tlv_type, data):

        except (core.RangeError, core.FieldError, core.MappingError,
    AttributeError: 'module' object has no attribute 'FieldError'

The explicit exception handling on parsing the lldp data is not required and this should be replaced by a general exception handler.

Version-Release number of selected component (if applicable):

How reproducible:

Every time introspection is run when using Version 2.8.22 of construct lib.

Steps to Reproduce:
1. Import baremetal node connected to network switch running lldp
2. Run introspection

Actual results:

Introspection fails with error as above.

Expected results:

Introspection passes.
