Subject: [PATCH 01/12] qapi: Don't suppress doc generation without pragma
 doc-required

Commit bc52d03ff5 "qapi: Make doc comments optional where we don't
need them" made scripts/qapi2texi.py fail[*] unless the schema had
pragma 'doc-required': true.  The stated reason was inability to cope
with incomplete documentation.

When commit fb0bc835e5 "qapi-gen: New common driver for code and doc
generators" folded scripts/qapi2texi.py into scripts/qapi-gen.py, it
turned the failure into silent suppression.

The doc generator can cope with incomplete documentation now.  I don't
know since when, or what the problem was, or even whether it ever
existed.

Drop the silent suppression.

[*] The fail part was broken, fixed in commit e8ba07ea9a.

Subject: [PATCH 02/12] qapi: Store pragma state in QAPISourceInfo, not global
 state

The frontend can't be run more than once due to its global state.
A future commit will want to do that.

Recent commit "qapi: Move context-sensitive checking to the proper
place" got rid of many global variables already, but pragma state is
still stored in global variables (that's why a pragma directive's
scope is the complete schema).

Move the pragma state to QAPISourceInfo.

Subject: [PATCH 03/12] qapi: Eliminate accidental global frontend state

The frontend can't be run more than once due to its global state.
A future commit will want to do that.

The only global frontend state remaining is accidental:
QAPISchemaParser.__init__()'s parameter previously_included=[].
Python evaluates the default once, at definition time.  Any
modifications to it are visible in subsequent calls.  Well-known
Python trap.  Change the default to None and replace it by the real
default in the function body.  Use the opportunity to convert
previously_included to a set.

Subject: [PATCH 04/12] qapi: Speed up frontend tests

"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.

Subject: [PATCH 05/12] qapi: Move gen_enum(), gen_enum_lookup() back to
 qapi/types.py

The next commit will split up qapi/common.py.  gen_enum() needs
QAPISchemaEnumMember, and that's in the way.  Move it to qapi/types.py
along with its buddy gen_enum_lookup().

Permit me a short a digression on history: how did gen_enum() end up
in qapi/common.py?  Commit 21cd70dfc1 "qapi script: add event support"
duplicated qapi-types.py's gen_enum() and gen_enum_lookup() in
qapi-event.py.  Simply importing them would have been cleaner, but
wasn't possible as qapi-types.py was a program, not a module.  Commit
efd2eaa6c2 "qapi: De-duplicate enum code generation" de-duplicated by
moving them to qapi.py, which was a module.

Since then, program qapi-types.py has morphed into module types.py.
It's where gen_enum() and gen_enum_lookup() started, and where they
belong.

Subject: [PATCH 06/12] qapi: Split up scripts/qapi/common.py

The QAPI code generator clocks in at some 3100 SLOC in 8 source files.
Almost 60% of the code is in qapi/common.py.  Split it into more
focused modules:

* Move QAPISchemaPragma and QAPISourceInfo to qapi/source.py.

* Move QAPIError and its sub-classes to qapi/error.py.

* Move QAPISchemaParser and QAPIDoc to parser.py.  Use the opportunity
  to put QAPISchemaParser first.

* Move check_expr() & friends to qapi/expr.py.  Use the opportunity to
  put the code into a more sensible order.

* Move QAPISchema & friends to qapi/schema.py

* Move QAPIGen and its sub-classes, ifcontext,
  QAPISchemaModularCVisitor, and QAPISchemaModularCVisitor to qapi/gen.py

* Delete camel_case(), it's unused since commit e98859a9b9 "qapi:
  Clean up after recent conversions to QAPISchemaVisitor"

A number of helper functions remain in qapi/common.py.  I considered
moving the code generator helpers to qapi/gen.py, but decided not to.
Perhaps we should rewrite them as methods of QAPIGen some day.

Subject: [PATCH 07/12] qapi: Clear scripts/qapi/doc.py executable bits again

Commit fbf09a2fa4 "qapi: add 'ifcond' to visitor methods" brought back
the executable bits.  Fix that.  Drop the #! line for good measure.

Command and event details are indented three spaces, everything else
four.  Messed up in commit 156402e5042.  Use four spaces consistently.

Subject: [PATCH 09/12] qapi: Add feature flags to commands

Similarly to features for struct types introduce the feature flags also
for commands. This will allow notifying management layers of fixes and
compatible changes in the behaviour of a command which may not be
detectable any other way.

The changes were heavily inspired by commit 6a8c0b51025.

Subject: [PATCH 11/12] tests/qapi-schema: Cover feature documentation comments

Commit 8aa3a33e44 "tests/qapi-schema: Test for good feature lists in
structs" neglected to cover documentation comments, and the previous
commit followed its example.  Make up for them.

Subject: [PATCH 12/12] qapi: Allow introspecting fix for savevm's cooperation
 with blockdev

'savevm' was buggy as it considered all monitor-owned block device
nodes for snapshot. With the introduction of -blockdev, the common
usage made all nodes including protocol and backing file nodes be
monitor-owned and thus considered for snapshot.

This is a problem since the 'file' protocol nodes can't have internal
snapshots and it does not make sense to take snapshot of nodes
representing backing files.

This was fixed by commit 05f4aced658a02b02. Clients need to be able to
detect whether this fix is present.

Since savevm does not have an QMP alternative, add the feature for the
'human-monitor-command' backdoor which is used to call this command in
modern use.
