f4c05aaf14 qapi/parser: Introduce NullSection
Here's the weird bit. QAPIDoc generally expects -- virtually everywhere
-- that it will always have a current section. The sole exception to
this is in the case that end_comment() is called, which leaves us with
*no* section. However, in this case, we also don't expect to actually
ever mutate the comment contents ever again.

NullSection is just a Null-object that allows us to maintain the
invariant that we *always* have a current section, enforced by static
typing -- allowing us to type that field as QAPIDoc.Section instead of
the more ambiguous Optional[QAPIDoc.Section].

end_section is renamed to switch_section and now accepts as an argument
the new section to activate, clarifying that no callers ever just
unilaterally end a section; they only do so when starting a new section.

1e20a77576 qapi/parser: clarify _end_section() logic
The "if self._section" clause in end_section is mysterious: In which
circumstances might we end a section when we don't have one?

QAPIDoc always expects there to be a "current section", only except
after a call to end_comment(). This actually *shouldn't* ever be 'None',
so let's remove that logic so I don't wonder why it's like this again in
three months.

cd87c14cde qapi/parser: remove FIXME comment from _append_body_line
True, we do not check the validity of this symbol -- but we don't check
the validity of definition names during parse, either -- that happens
later, during the expr check. I don't want to introduce a dependency on
expr.py:check_name_str here and introduce a cycle.

Instead, rest assured that a documentation block is required for each
definition. This requirement uses the names of each section to ensure
that we fulfilled this requirement.

e.g., let's say that block-core.json has a comment block for
"Snapshot!Info" by accident. We'll see this error message:

In file included from ../../qapi/block.json:8:
../../qapi/block-core.json: In struct 'SnapshotInfo':
../../qapi/block-core.json:38: documentation comment is for 'Snapshot!Info'

That's a pretty decent error message.

Now, let's say that we actually mangle it twice, identically:

../../qapi/block-core.json: In struct 'Snapshot!Info':
../../qapi/block-core.json:38: struct has an invalid name

That's also pretty decent. If we forget to fix it in both places, we'll
just be back to the first error.

Therefore, let's just drop this FIXME and adjust the error message to
not imply a more thorough check than is actually performed.

2adb988ed4 qapi/gen: use dict.items() to iterate over _modules
New pylint warning. I could silence it, but this is the only occurrence
in the entire tree, including everything in iotests/ and python/. Easier
to just change this one instance.

(The warning is emitted in cases where you are fetching the values
anyway, so you may as well just take advantage of the iterator to avoid
redundant lookups.)

4e99f4b12c qapi: Drop simple unions
Simple unions predate flat unions.  Having both complicates the QAPI
schema language and the QAPI generator.  We haven't been using simple
unions in new code for a long time, because they are less flexible and
somewhat awkward on the wire.

The previous commits eliminated simple union from the tree.  Now drop
them from the QAPI schema language entirely, and update mentions of
"flat union" to just "union".

I'm about to convert simple unions to flat unions, then drop simple
union support.  The conversion involves making the implict enum types
explicit.  To reduce churn, I'd like to name them exactly like the
implicit types they replace.  However, these names are reserved for
the generator's use.  They won't be once simple unions are gone.  Stop
enforcing this naming rule now rather than then.

dfc86c0f25 fuzz: add an instrumentation filter
By default, -fsanitize=fuzzer instruments all code with coverage
information. However, this means that libfuzzer will track coverage over
hundreds of source files that are unrelated to virtual-devices. This
means that libfuzzer will optimize inputs for coverage observed in timer
code, memory APIs etc. This slows down the fuzzer and stores many inputs
that are not relevant to the actual virtual-devices.

With this change, clang versions that support the
"-fsanitize-coverage-allowlist" will only instrument a subset of the
compiled code, that is directly related to virtual-devices.

b32abbb2f5 qapi: Fix crash on redefinition with a different condition
QAPISchema._make_implicit_object_type() asserts that when an implicit
object type is used multiple times, @ifcond is the same for all uses.
It will be for legitimate uses, i.e. simple union branch wrapper
types.  A comment explains this.

The assertion fails when a command or event is redefined with a
different condition.  The redefinition is an error, but it's flagged
only later.

Fixing the assertion would complicate matters further.  Not
worthwhile, drop it instead.  We really need to get rid of simple
unions.

Tweak test case redefined-event to cover redefinition with a different
condition.

memory areas allocated by GLib functions not included in model.c,
such as g_strfreev.  This unfortunately goes against the GLib
documentation, which suggests that g_malloc() should be matched
with g_free() and plain malloc() with free(); since GLib 2.46 however
g_malloc() is hardcoded to always use the system malloc implementation,
and g_free is just "free" plus a tracepoint.  Therefore, this
should not cause any problem in practice.

d4b3d152ee coverity-model: update address_space_read/write models
Use void * for consistency with the actual function; provide a model
for MemoryRegionCache functions and for address_space_rw.  These
let Coverity understand the bounds of the data that various functions
read and write even at very high levels of inlining (e.g. pci_dma_read).

a0c7b99bf7 qapi: Fix crash on missing enum member name
New test case enum-dict-no-name.json crashes:

    $ python3 scripts/qapi-gen.py tests/qapi-schema/enum-dict-no-name.json
    Traceback (most recent call last):
    [...]
      File "/work/armbru/qemu/scripts/qapi/expr.py", line 458, in check_enum
	member_name = member['name']
    KeyError: 'name'

Root cause: we try to retrieve member 'name' before we check for
missing members.  With that fixed, we get the expected error "'data'
member misses key 'name'".

40de78c284 Jobs based on custom runners: docs and gitlab-runner setup playbook
To have the jobs dispatched to custom runners, gitlab-runner must
be installed, active as a service and properly configured.  The
variables file and playbook introduced here should help with those
steps.

The playbook introduced here covers the Linux distributions and
has been primarily tested on OS/machines that the QEMU project
has available to act as runners, namely:

 * Ubuntu 20.04 on aarch64
 * Ubuntu 18.04 on s390x

But, it should work on all other Linux distributions.  Earlier
versions were tested on FreeBSD too, so chances of success are
high.

159c5d177b Jobs based on custom runners: build environment docs and playbook
To run basic jobs on custom runners, the environment needs to be
properly set up.  The most common requirement is having the right
packages installed.

The playbook introduced here covers the QEMU's project s390x and
aarch64 machines.  At the time this is being proposed, those machines
have already had this playbook applied to them.

2adf216491 qemu-trace-stap: changing SYSTEMTAP_TAPSET considered harmful.
Setting SYSTEMTAP_TAPSET to some value other than
/usr/share/systemtap/tapsets results in systemtap not finding the
standard tapset library any more, which in turn breaks tracing because
pid() and other standard systemtap functions are not available any more.

So using SYSTEMTAP_TAPSET to point systemtap to the qemu probes will
only work for the prefix=/usr installs because both qemu and system
tapsets in the same directory then.  All other prefixes are broken.

Fix that by using the "-I $tapsetdir" command line switch instead.

6be7206efc scripts/qmp-shell: move to python/qemu/qmp/qmp_shell.py
The script will be unavailable for a commit or two, which will help
preserve development history attached to the new file. A forwarder will
be added shortly afterwards.

With qmp_shell in the python qemu.qmp package, now it is fully type
checked, linted, etc. via the Python CI. It will be quite a bit harder
to accidentally break it again in the future.

d1d14e5989 scripts/qmp-shell: Use context manager instead of atexit
We can invoke the shell history writing when we leave the QMPShell scope
instead of relying on atexit. Doing so may be preferable to avoid global
state being registered from within a class instead of from the
application logic directly.

Use QMP's context manager to hook this history saving at close time,
which gets invoked when we leave the context block.
