Pending prerequisite: Markus' qapi-next branch (which has my
subset A patches):
git://repo.or.cz/qemu/armbru.git qapi-next
http://thread.gmane.org/gmane.comp.emulators.qemu/365827/focus=366351
as well as my subset B patches (currently at v7):
http://article.gmane.org/gmane.comp.emulators.qemu/366810
http://repo.or.cz/qemu/ericb.git/shortlog/refs/tags/qapi-cleanupv7b
Also available as a tag at this location:
git fetch git://repo.or.cz/qemu/ericb.git qapi-cleanupv6c
and I plan to eventually forcefully update my branch with the rest
of the v5 series, at:
http://repo.or.cz/qemu/ericb.git/shortlog/refs/heads/qapi
v6 notes:
Add some patches and rebase onto work on subset B. Rearrange some
patches from v5 (this set includes 17-20, 23, 25-27). Backport diff
gets a bit confused by one patch title changing.

Not much direct review comments, although some of the changes here
are updated based on comments made on other patches in the v5 series.
Subset D (and more?) will come later.
In v5:
https://lists.gnu.org/archive/html/qemu-devel/2015-09/msg05410.html
I _did_ rearrange patches to try and group related features:
1-2: Groundwork cleanups
3-5: Add more test cases
6-16: Front-end cleanups
17-18: Introspection output cleanups
19-20: 'alternate' type cleanups
21-29: qapi visitor cleanups
30-45: qapi-ify netdev_add
46: add qapi shorthand for flat unions
Lots of fixes based on additional testing, and rebased to
track other changes that happened in the meantime. The series
is huge; I can split off smaller portions as requested.
In v4:
https://lists.gnu.org/archive/html/qemu-devel/2015-09/msg02580.html
add some more clean up patches
rebase to Markus' recent work
pull in part of Zoltán's work to make netdev_add a flat union,
further enhancing it to be introspectible
I might be able to rearrange some of these patches, or separate
it into smaller independent series, if requested; but I'm
posting now to get review started.
In v3:
https://lists.gnu.org/archive/html/qemu-devel/2015-08/msg02059.html
redo cleanup of dealloc of partial struct
add patches to make all visit_type_*() avoid leaks on failure
add patches to allow boxed command arguments and events
In v2:
https://lists.gnu.org/archive/html/qemu-devel/2015-08/msg00900.html
rebase to Markus' v3 series
rework how comments are emitted for fields inherited from base
additional patches added for deleting colliding 'void *data'
documentation updates to match code changes
v1 was here:
https://lists.gnu.org/archive/html/qemu-devel/2015-07/msg05266.html
https://lists.gnu.org/archive/html/qemu-devel/2015-07/msg05325.html

Rather than just asserting that we can parse an empty enum,
let's also make sure we can compile it, by including it in
qapi-schema-test.

qapi-schema-test was already testing that we could have a
command returning int, but burned a command name in the whitelist.
Merge the redundant positive test returns-int, and pick a name
that reduces the whitelist size.

As of commit 8c3f8e77, we test compilation of forward references
for a struct base type (UserDefOne), flat union base type
(UserDefUnionBase), and flat union branch type
(UserDefFlatUnion2). The only remaining forward reference being
tested for parsing in flat-union-reverse-define was a forward
enum declaration. Once we make sure that always compiles,
the smaller parse-only test is redundant and can be deleted.

To: qemu-devel; +Cc: armbru, Michael Roth
Commit d88f5fd and friends first introduced the various test-qmp-*
tests in 2011, with duplicated hand-rolled TestStruct machinery,
to make sure the qapi visitor interface was tested. Later, commit
4f193e3 in 2013 added a .json file for further testing use by the
files, but without consolidating any of the existing hand-rolled
visitors. And with four copies, subtle differences have crept in.
Of course, just because the visitor interface is tested does not
mean it is a sane interface; and future patches will be changing
some of the visitor contracts. Rather than having to duplicate
the cleanup work in each copy of the TestStruct visitor, and keep
each hand-rolled copy in sync with what the generator supplies, we
might as well just test what the generator should give us in the
first place.

For the sake of humans reading introspection output, it is nice
to have the name of implicit array types be recognizable as
arrays of the underlying type. However, while this patch allows
humans to skip from a command with return type "[123]" straight
to the definition of type "123" without having to first inspect
type "[123]", document that this shortcut should not be taken by
client apps.
This makes the resulting introspection string slightly larger by
default, but slightly smaller when -u is in use (as '[FOO]' is
nicer than 'FOOList' for expressing 'array of FOO').

Sorting the values of an enum makes it easier to look up whether
a particular value is present by binary rather than linear search
(probably most visible with QKeyCode, which has grown over
several releases). Additionally, QMP clients need not know which
C value is associated with an enum name, so sorting is an
effective way to hide that non-ABI aspect of qapi.
While we are at it, it is also easy to sort the members and
variants of objects, to allow for a similar binary search, and
equally valid since JSON objects have no specific order in which
keys must appear. There is no trivial or obvious way to sort
the types of an alternate, so that is left unchanged.
However, the overall SchemaInfo array remains unsorted. It might
make sense to sort with 'meta-type' as a primary key and 'name'
as a secondary key, but it is not obvious that this will provide
benefits to end-user clients (we allow mutually recursive types,
so there is no posible topological sorting where a single pass
over the array could resolve all types, and while binary searches
could be made possible by sorting, it would be even more efficient
for clients to read the array into a hashtable for O(1) rather
than O(log n) random-access lookups, at which point pre-sorting is
wasted effort).
Document these conventions, so that clients will know what can
and cannot be relied on.
Signed-off-by: Eric Blake <eblake@redhat.com>

TODO: should the documentation mention that the sorting is done
in the C locale? Is there anything required to ensure that python
sorts sanely (ie. that the choice of locale while building
doesn't cause inadvertent sorting differences such as turning on
case-insensitivity)?

Prepare to simplify alternate layout by creating a dedicated
subclass for the generated tag type. QMP does not transmit
the tag name, so we can name it whatever we want in C. But
since the tag is closely tied to a qtype_code, this commit
renames the tag from 'kind' to 'type', so the next commit can
then further modify things to use a simpler 'qtype_code type;'
for the tag. As part of this, a new member.c_type() method
will make it possible to express the tag type even if there
is no qapi entity type associated with the tag.

Previously, working with alternates required two enums, and
some indirection: for type Foo, we created Foo_qtypes[] which
maps each qtype to a member of FooKind_lookup[], then use
FooKind_lookup[] like we do for other union types.
This has a subtle bug: since the values of FooKind_lookup
start at zero, all entries of Foo_qtypes that were not
explicitly initialized map to the same branch of the union as
the first member of the alternate, rather than triggering a
failure in visit_get_next_type(). Fortunately, the bug
seldom bites; the very next thing the input visitor does is
try to parse the incoming JSON with the wrong parser, which
fails; the output visitor is not used with a C struct in that
state, and the dealloc visitor has nothing to clean up (so
there is no leak).
However, it IS observable in one case: the behavior of an
alternate that contains a 'number' member but no 'int' member
differs according to whether the 'number' was first in the
qapi definition, and when the input being parsed is an integer;
this is because the 'number' parser accepts QTYPE_QINT in
addition to the expected QTYPE_QFLOAT. A later patch will worry
about fixing alternates to parse all inputs that a non-alternate
'number' would accept, for now it is still marked FIXME.
This patch fixes the validation bug by deleting the indirection,
and modifying get_next_type() to directly return a qtype code.
There is no longer a need to generate an implicit FooKind array
associated with the alternate type (since the QMP wire format
never uses the stringized counterparts of the C union member
names). Next, the generated visitor is fixed to properly detect
unexpected qtypes in the switch statement. With a bit of work
to the previously-added QAPISchemaAlternateTypeTag, we can wrap
the layout change so that spots in qapi-types that are shared
with other unions still work.
Callers now have to know the QTYPE_* mapping when looking at the
discriminator; but so far, only the testsuite was even using the
C struct of an alternate types. If that gets too confusing, we
could reintroduce FooKind, but initialize it differently than
most generated arrays, as in:
typedef enum FooKind {
FOO_KIND_A = QTYPE_QDICT,
FOO_KIND_B = QTYPE_QINT,
} FooKind;
to create nicer aliases for knowing when to use foo->a or foo->b
when inspecting foo->type. But without a current client, I
didn't see the point of doing it now.
There is a user-visible side effect to this change, but I
consider it to be an improvement. Previously,
the invalid QMP command:
{"execute":"blockdev-add", "arguments":{"options":
{"driver":"raw", "id":"a", "file":true}}}
failed with:
{"error": {"class": "GenericError",
"desc": "Invalid parameter type for 'file', expected: QDict"}}
Now it fails with:
{"error": {"class": "GenericError",
"desc": "Invalid parameter type for 'file', expected: BlockdevRef"}}

From: Eric Blake @ 2015-10-08 2:00 UTC (permalink / raw)
To: qemu-devel; +Cc: armbru, Michael Roth
The QMP input visitor allows integral values to be assigned by
promotion to a QTYPE_QFLOAT. However, when parsing an alternate,
we did not take this into account, such that an alternate that
accepts 'number' but not 'int' would reject integral values.
With this patch, we now have the following desirable table:
alternate has case selected for
'int' 'number' QTYPE_QINT QTYPE_QFLOAT
no no error error
no yes 'number' 'number'
yes no 'int' error
yes yes 'int' 'number'
While it is unlikely that we will ever use 'number' in an
alternate other than in the testsuite, it never hurts to be
more precise in what we allow.

Commit cbc95538 removed unused start_handle() and end_handle(),
but forgot got remove their declarations.
Commit 4e27e819 introduced optional visitor callbacks for all
sorts of int types, but except for type_uint64 and type_size,
none of them have ever been supplied (the generic implementation
based on using type_int then bounds-checking works just fine).
In the interest of simplicity, it's easier to make the visitor
callback interface not have to worry about the other sizes.

Make valgrind happy with the current state of the tests, so that
it is easier to see if future patches introduce new memory problems
without being drowned in noise. Many of the leaks were due to
calling a second init without tearing down the data from an earlier
visit. But since teardown is already idempotent, and we already
register teardown as part of input_visitor_test_add(), it is nicer
to just make init() safe to call multiple times than it is to have
to make all tests call teardown.
Another common leak was forgetting to clean up an error object,
after testing that an error was raised.
Another leak was in test_visitor_in_struct_nested(), failing to
clean the base member of UserDefTwo. Cleaning that up left
check_and_free_str() as dead code (since using the qapi_free_*
takes care of recursion, and we don't want double frees).

v6: make init repeatable rather than adding teardown everywhere,
fix additional leak with UserDefTwo base, plug additional files

By using &error_abort, we can avoid a local err variable in
situations where we expect success.
By moving err into data, we can let test teardown take care
of cleaning up any collected error (and allowing for fewer
lines of code between repeated tests where init runs teardown
on our behalf).

Our generated list visitors have the same problem as has been
mentioned elsewhere (see commit 2f52e20): they allocate data
even on failure. An upcoming patch will correct things to
provide saner guarantees, but first we need to expose the
behavior in the testsuite to ensure we aren't introducing any
memory usage bugs.

Our testsuite had no coverage of empty arrays, nor of what
happens when the input does not match the expected type.
Useful to have, especially if we start changing the visitor
contracts.

None of the visitor callbacks would set an error when testing
if an optional field was present; make this part of the interface
contract by eliminating the errp argument. Then, for less code,
reflect the determined boolean value back to the caller instead
of making the caller read the boolean after the fact.
The resulting generated code has a nice diff:
|- visit_optional(v, &has_fdset_id, "fdset-id", &err);
|- if (err) {
|- goto out;
|- }
|- if (has_fdset_id) {
|+ if (visit_optional(v, &has_fdset_id, "fdset-id")) {
| visit_type_int(v, &fdset_id, "fdset-id", &err);
| if (err) {
| goto out;
| }
| }

I'm about to post a rebase of this series, depending on my recent subset
B' v9, if that affects any reviewer's plans.

Meanwhile, these three already got hoisted into subset B and are in a
pending pull request.

and this one may disappear completely, since v9B does the rename to type
in a cleaner fashion.
