11:40 a.m.
There is an online service call LGTM (Looks Good To Me) which does
static analysis of open source projects and I happened to learn that
they include coverage of libvirt
https://lgtm.com/projects/g/libvirt/libvirt
I looked at the alerts they reported. Currently no errors, 41 warnings
and 90 recommendations (79 of which are FIXME comments :-).
There's nothing particularly important they identify right now, but I
felt like addressing a few of them anyway, hence this series.

New subject: [libvirt] [PATCH 1/6] conf: remove pointless check on enum value
'val' is initialized from virDomainCapsFeatureTypeFromString and a
few lines earlier there was already a check for 'val < 0'.
The 'val >= 0' is thus always true. The enum conversion similarly
ensures that the val will be less than VIR_DOMAIN_CAPS_FEATURE_LAST,
so "val < VIR_DOMAIN_CAPS_FEATURE_LAST' is thus always true too.

This caught my eye...
Since @val was sourced from virDomainCapsFeatureTypeFromString so one
would think it should use virDomainCapsFeatureTypeToString(val) at the
very least. Or use 'nodes[i]->name' directly.
As a test I modified tests/domainschemadata/domain-caps-features.xml to
set state to "foo" and then creating the lxc guest would result in :
error: unsupported configuration: unknown state attribute 'foo' of
feature capability 'hpt'
fixing to use DomainCapsFeature got:
error: unsupported configuration: unknown state attribute 'foo' of
feature capability 'mknod'
I checked other virDomainFeatureTypeToString callers and they all seemed
OK - it was just this one.

PEP 8 says:
"Comparisons to singletons like None should always be done

There are potentially semantics differences, though in the case of this
libvirt code its merely a style change:

New subject: [libvirt] [PATCH 6/6] hyperv: use "is None" not "== None" for PEP-8 compliance

"Comparisons to singletons like None should always be done
with 'is' or 'is not', never the equality operators."
There are potentially semantics differences, though in the case of this
libvirt code its merely a style change:
