"make check-qapi-schema" takes around 10s user + system time for me.
With -j, it takes a bit over 3s real time. We have worse tests. It's
still annoying when you work on the QAPI generator.
Some 1.4s user + system time is consumed by make figuring out what to
do, measured by making a target that does nothing. There's nothing I
can do about that right now. But let's see what we can do about the
other 8s.
Almost 7s are spent running test-qapi.py for every test case, the rest
normalizing and diffing test-qapi.py output. We have 190 test cases.
If I downgrade to python2, it's 4.5s, but python2 is a goner.
Hacking up test-qapi.py to exit(0) without doing anything makes it
only marginally faster. The problem is Python startup overhead.
Our configure puts -B into $(PYTHON). Running without -B is faster:
4.4s.
We could improve the Makefile to run test cases only when the test
case or the generator changed. But I'm after improvement in the case
where the generator changed.
test-qapi.py is designed to be the simplest possible building block
for a shell script to do the complete job (it's actually a Makefile,
not a shell script; no real difference). Python is just not meant for
that. It's for bigger blocks.
Move the post-processing and diffing into test-qapi.py, and make it
capable of testing multiple schema files. Set executable bits while
there.
Running it once per test case now takes slightly longer than 8s. But
running it once for all of them takes under 0.2s.
Messing with the Makefile to run it only on the tests that need
retesting is clearly not worth the bother.
Expected error output changes because the new normalization strips off
$(SRCDIR)/tests/qapi-schema/ instead of just $(SRCDIR)/.
The .exit files go away, because there is no exit status to test
anymore.

We document that members of enums and objects should be
'lower-case', although we were not enforcing it. We have to
whitelist a few pre-existing entities that violate the norms.
Add three new tests to expose the new error message, each of
which first uses the whitelisted name 'UuidInfo' to prove the
whitelist works, then triggers the failure (this is the same
pattern used in the existing returns-whitelist.json test).
Note that by adding this check, we have effectively forbidden
an entity with a case-insensitive clash of member names, for
any entity that is not on the whitelist (although there is
still the possibility to clash via '-' vs. '_').
Not done here: a future patch should also add naming convention
support and whitelist exceptions for command, event, and type
names.
The additions to QAPISchemaMember.check_clash() check whether
info['name'] is in the whitelist (the top-most entity name at
the point 'info' tracks), rather than self.owner (the type,
possibly implicit, that directly owns the member), because it
is easier to maintain the whitelist by the names actually in
the user's .json file, rather than worrying about the names
of implicit types.
