Caution, rough edges.
qapi/introspect.json defines the introspection schema. It should do
for uses other than QMP.
FIXME it's almost entirely devoid of comments.
The introspection schema does not reflect all the rules and
restrictions that apply to QAPI schemata. A valid QAPI schema has an
introspection value conforming to the introspection schema, but the
converse is not true.
Introspection lowers away a number of schema details:
* The built-in types are declared with their JSON type.
TODO Should we map all the integer types to just int?
* Implicit type definitions are made explicit, and given
auto-generated names. These names start with ':' so they don't
clash with the user's names.
Example: a simple union implicitly defines an enumeration type for
its discriminator.
* All type references are by name.
* Base types are flattened.
* The top type (named 'any') can hold any value.
* The struct and union types are generalized into an object type.
* Commands take a single argument and return a single result.
Dictionary argument/result or list result is an implicit type
definition.
The empty object type is used when a command takes no arguments or
produces no results.
The argument is always of object type, but the introspection schema
doesn't reflect that.
The 'gen': false and 'success-response': false directives are
omitted as implementation detail.
* Events carry a single data value.
Implicit type definition and empty object type use, just like for
commands.
The value is of object type, but the introspection schema doesn't
reflect that.
* Types not used by commands or events are omitted.
Indirect use counts as use.
* Optional members have a default, which can only be null right now
Instead of a mandatory "optional" flag, we have an optional default.
No default means mandatory, default null means optional without
default value. Non-null is available for optional with default.
Alternate members can't have defaults, but the introspection schema
doesn't reflect that.
* Clients should *not* look up types by name, because type names are
not ABI. Look up the command or event you're interested in, then
follow the references.
TODO Should we hide the type names to eliminate the temptation?
* Likewise, the names of alternate members are not ABI, and should not
be examined.
TODO Should we hide them, too?
TODO much of the above should go into docs.
New generator scripts/qapi-introspect.py computes an introspection
value for its input, and generates a C variable holding it.
FIXME it can generate awfully long lines
A new test-qmp-input-visitor test case feeds its result for both
tests/qapi-schema/qapi-schema-test.json and qapi-schema.json to a
QmpInputVisitor to verify it actually conforms to the schema.
New QMP command query-schema takes its return value from that
variable. Command documentation is incomplete, and marked FIXME. Its
reply is some 80KiBytes for me right now.
If this turns out to be too much, we have a couple of options:
* We can use shorter names in the JSON. Not the QMP style.
* Optionally return the sub-schema for commands and events given as
arguments.
Right now qmp_query_schema() sends the string literal computed by
qmp-introspect.py. To compute sub-schema at run time, we'd have to
duplicate parts of qapi-introspect.py in C. Unattractive.
* Let clients cache the output of query-schema.
It changes only on QEMU upgrades, i.e. rarely. Provide a command
query-schema-hash. Clients can have a cache indexed by hash, and
re-query the schema only when they don't have it cached.
