Commit Message

John Snow Sept. 22, 2020, 9 p.m. UTC
Using `pylint --generate-rcfile > pylintrc`, generate a skeleton
pylintrc file. Sections that are not presently relevant (by the end of
this series) are removed leaving just the empty section as a search
engine / documentation hint to future authors.

Right now, quite a few modules are ignored as they are known to fail as
of this commit. modules will be removed from the known-bad list
throughout this and following series as they are repaired.

Note: Normally, pylintrc would go in the folder above the module, but as
that folder is shared by many things, it is going inside the module
folder (for now). Due to a bug in pylint 2.5.x, pylint does not
correctly recognize when it is being run from "inside" a package, and
must be run *outside* of the package.

Therefore, to run it, you must:

 > pylint scripts/qapi/ --rcfile=scripts/qapi/pylintrc

This doesn't generate any warnings after this patch, but at the
end of your -pt6 branch I got some pylint warnings.  I am
bisecting it to try to identify the patch where the warnings are
introduced.

One concern I have here is that the pylint version is not defined.
Based on experience, different pylint will behave differently, because
among other things, it may introduce new checks.

I'd at the very least document the pylint version used in the commit
message, until a "requirements.txt"-like solution pinning a version is
given.

Other than that,

Alright, I'll put it in the commit message itself instead of in the 
cover letter.

The next step is to re-engage on that Makefile patch that I was working 
on for ./python/qemu and introduce it here too, which will document the 
pinned versions correctly.

I missed that info on the cover letter, so my apologies.  But still, I
think it's a good idea to have that preserved in the repo history
indeed.
