I wrote this series for several reasons:
1. I've been doing a lot of churn in the qapi visitor interfaces
lately; adding a new visitor is good proof whether the changes
still make sense
2. Alexander ended up writing his own simple JSON generator as
qjson.c in his work for vmstate self-description, rather than
reusing existing code, because the QObject JSON generator does
not have an easy entry point
3. Fam commented while trying to enhance 'qemu-img map' that we
are rather wasteful in that there is no way to go directly from
a qapi type to JSON without an intermediate QObject creation
RFC because it conflicts with other pending qemu-img patches:
https://lists.gnu.org/archive/html/qemu-devel/2015-12/msg01756.html
and because I still have testsuite failures in qemu-iotests that
must be addressed before the series can be applied (some output
reordering occurs, but it also flushed out some clients that are
abusing qapi visits by expecting NULL to turn into ""). Posting
now to at least get feedback on whether the ideas make sense.
Pending prerequisites:
+ Markus' qapi-not-next branch (including my qapi subset D patches):
http://repo.or.cz/qemu/armbru.git/shortlog/refs/heads/qapi-not-next
https://lists.gnu.org/archive/html/qemu-devel/2015-12/msg00463.html
+ v8 or later of my qapi subset E patches (at the time of this mail,
only v7 has been posted):
https://lists.gnu.org/archive/html/qemu-devel/2015-12/msg01181.html
Also available as a tag at this location (with prerequisites applied):

We have two different JSON visitors in the tree; and having both
named 'qjson.h' can cause include confusion. Rename the qapi
version.
Kill trailing whitespace in the renamed tests/check-qobject-json.c
to keep checkpatch.pl happy.

* [Qemu-devel] [PATCH 01/11] qapi: Rename qjson.h to qobject-json.h

We have two different JSON visitors in the tree; and having both
named 'qjson.h' can cause include confusion. Rename the qapi
version.
Kill trailing whitespace in the renamed tests/check-qobject-json.c
to keep checkpatch.pl happy.

'qobject-json.h' is not a QObject subtype; include this file
directly in .c files that are using it, rather than abusing
qmp/types.h for that purpose.
Meanwhile, for files that include a list of individual QObject
subtypes, it's easier to just use qmp/types.h for that purpose.

Pull out a new qstring_append_json_string() helper, so that all
JSON output producers can use the same output escaping rules.
While it appears that vmstate's use of the simpler qjson.c
formatter is not currently encountering any string that needs
escapes to be valid JSON, it is better to be safe than sorry.

Pull out a new qstring_append_json_number() helper, so that all
JSON output producers can use a consistent style for printing
floating point without duplicating code (since we are doing more
data massaging than a simple printf format).
Address one FIXME by adding an Error parameter and warning the
caller if the requested number cannot be represented in JSON;
but add another FIXME in its place because we have no way to
report the problem higher up the stack.

Back in commit 764c1ca (Nov 2009), we added qstring_append_int().
However, it did not see any use until commit 190c882 (Jan 2015).
Furthermore, it has a rather limited use case - to print anything
else, callers still have to format into a temporary buffer, unless
we want to introduce an explosion of new qstring_append_* methods
for each useful type to print.
A much better approach is to add a wrapper that merges printf
behavior onto qstring_append, via the new qstring_append_format()
(and its vararg counterpart). In fact, with that in place, we
no longer need qstring_append_int().
Other immediate uses for the new function include simplifying
an existing client of qstring_append() on a just-formatted
buffer, and the fact that we can take advantage of printf width
manipulations for more efficient indentation.

From: Eric Blake @ 2015-12-10 23:53 UTC (permalink / raw)
To: qemu-devel; +Cc: Markus Armbruster, Michael Roth
We have several places that want to go from qapi to JSON; right now,
they have to create an intermediate QObject to do the work. That
also has the drawback that the JSON formatting of a QDict will
rearrange keys (according to a deterministic, but unpredictable,
hash), when humans have an easier time if dicts are produced in
the same order as the qapi type.
For these reasons, it is time to add a new JSON output visitor.
This patch just adds the basic visitor and tests that it works;
later patches will add pretty-printing, and convert clients to
use the visitor.
Design choices: Unlike the QMP output visitor, the JSON visitor
refuses to visit a required string with a NULL value (abort), as
well as a non-finite number (raises an error message). Reusing
QString to grow the contents means that we easily share code with
both qobject-json.c and qjson.c; although it might be nice to
enhance things to take an optional output callback function so
that the output can truly be streamed instead of collected in
memory.

Instead of rolling our own limited JSON outputter, we can just
wrap the more full-featured JSON output Visitor.
This slightly changes the output (different spacing), but the
result is still equivalent JSON contents.

The next patch will add pretty indentation to the JSON visitor.
But in order to support pretty output in the type_any() callback,
we need to prefix every line of the QObject visitor by the current
indentation in the JSON visitor. Hence, a new function
qobject_to_json_pretty_indent(), and the old function becomes a
thin wrapper to the expanded behavior.
While at it, change 'pretty' to be a bool, to match its usage.
Note that the new simple_pretty() test is a bit sensitive to our
current notion of prettiness, as well as to the hash ordering in
QDict (most of the tests in check-qobject-json intentionally do
not compare the original string to the round-trip string, because
we liberally accept more input forms than the canonical form that
we output).

Similar to pretty printing in the QObject visitor. Trickiest
parts are the fact that during type_any(), we have to coordinate
with QObject to also print pretty; and the fact that the testsuite
now has to honor parameterization on whether pretty printing is
enabled.

Now that we can pretty-print straight to JSON from a visitor,
we can eliminate the temporary conversion into QObject inside
qemu-img.
RFC because at least qemu-iotests 043 has changed output, not
included in this version of the patch. Conflicts with Fam's
qemu-img edits, so one of the two of us will get to rebase on
the other:

Hmm. The generated qapi callers always pass a non-NULL local errp, and
fail the overall iteration even if the upper-level caller passed NULL.
My intent here was to allow the choice between diagnosing NaN, or
ignoring the problem and producing output anyways; but for that to work,
I may need to add a configuration parameter 'bool strict' at the
creation of the visitor, that determines whether I pass errp or NULL on
to qstring_append_json_number() here.

I touched qemu-img map's output, this patch updates info and check, so the
context conflict should be okay, but it would be better to get this patch in
before mine so I can update my patch to make use of the new formatter, without
code churn.
Thanks!

compiles and is pretty much a 1:1 translation from the qjson.c API to the
visitor API (using this patch as a guide). Feel free to include it and
remove qjson.c. Alternatively, you can leave out this patch and I'll test
and submit the transition.

Mentioned in the cover letter:
+ v8 or later of my qapi subset E patches (at the time of this mail,
only v7 has been posted):
https://lists.gnu.org/archive/html/qemu-devel/2015-12/msg01181.html
Also available as a tag at this location (with prerequisites applied):
git fetch git://repo.or.cz/qemu/ericb.git qapi-jsonv1
(note that it is only a tag, not a branch, and you are right that it
doesn't yet apply to any maintainer's tree).

Should I squash the two together, or keep my current patch and drop
qjson.c as a separate patch?
Also, while reading this, I noticed that qjson.h has signatures that
match JSON ('name' comes before 'value', when generating a "name":value
pair), while visitor.h has signatures that are backwards ('obj' comes
before 'name', even though the output will be "name":value-of-obj). I'm
seriously debating about a tree-wide coccinelle patch to reverse the
order or arguments of all the visit_type_* functions.

That would be doable, there aren't many users outside generated code.

visit_type_int() takes 'int64_t*', not 'int'. In places, that means I'd
have to add a temporary variable to cover the fact that the input is not
the right type for writing '&size'

...or even cover the case where it is a constant whose address does not
even exist.

So the patch to avoid qjson.c is not quite 1:1. Still, I'll go ahead and
complete the patch for my v2, to see if you still like it.
