[Qemu-devel] [PATCH v3 00/13] qapi: Test coverage & clean up generated code

[Markus Armbruster <armbru@redhat.com>]

Coverity is unhappy with the generated code.  Nothing serious, just
heaps of valid DEADCODE defects topped off with a few bogus
FORWARD_NULL defects.

I had a look at the generator, and decided I don't want to mess with
it without decent test coverage.  Unfortunately, a few features have
been added without tests.  My first seven patches make the tests catch
up.  tests/qapi-schema/qapi-schema-test.json now covers all mcgen() in
scripts/qapi*.py, except for a few in qapi-commands.py that are
conditional on -m.

The next four patches clean up the generated code.

I also reviewed null checks in visitor implementations.  The final two
patches address the issues I found there.

v3:
* Trivially rebased

v2:
* Previously separate patch "qapi: Fix licensing of scripts" revised
  and included as "[PATCH v2 08/13] qapi: Fix licensing of scripts"
* Style cleanups
* New PATCH 12/13 and 13/13
