qapi/introspect.json defines the introspection schema. It's designed for QMP introspection, but should do for similar uses, such as QGA. 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, and makes implicit things explicit: * The built-in types are declared with their JSON type. All integer types are mapped to 'int', because how many bits we use internally is an implementation detail. It could be pressed into external interface service as very approximate range information, but that's a bad idea. If we need range information, we better do it properly. * Implicit type definitions are made explicit, and given auto-generated names: - Array types, named by appending "List" to the name of their element type, like in generated C. - The enumeration types implicitly defined by simple union types, named by appending "Kind" to the name of their simple union type, like in generated C. - Types that don't occur in generated C. Their names start with ':' so they don't clash with the user's names. * All type references are by name. * The struct and union types are generalized into an object type. * Base types are flattened. * Commands take a single argument and return a single result. Dictionary argument 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 directive is omitted as implementation detail. The 'success-response' directive is omitted as well for now, even though it's not an implementation detail, because it's not used by QMP. * 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 (possible future extension). * 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? New generator scripts/qapi-introspect.py computes an introspection value for its input, and generates a C variable holding it. It can generate awfully long lines. Marked TODO. 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-qmp-schema takes its return value from that variable. Its reply is some 85KiBytes 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-qmp-schema. It changes only on QEMU upgrades, i.e. rarely. Provide a command query-qmp-schema-hash. Clients can have a cache indexed by hash, and re-query the schema only when they don't have it cached. Even simpler: put the hash in the QMP greeting. Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Reviewed-by: NEric Blake <eblake@redhat.com>

Before commit 1d10b445, it crashed. Since then, it returns NULL, with a FIXME comment. The FIXME is valid: code that assumes QObject * can't be null exists. I'm not aware of a way to feed this problematic return value to code that actually chokes on null in the current code, but the next few commits will create one, failing "make check". Commit 481b002c solved a very similar problem by introducing a special null QObject. Using this special null QObject is clearly the right way to resolve this FIXME, so do that, and update the test accordingly. However, the patch isn't quite right: it messes up the reference counting. After about SIZE_MAX visits, the reference counter overflows, failing the assertion in qnull_destroy_obj(). Because that's many orders of magnitude more visits of nulls than we expect, we take this patch despite its flaws, to get the QMP introspection stuff in without further delay. We'll want to fix it for real before the release. Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Reviewed-by: NEric Blake <eblake@redhat.com> Reviewed-by: NDaniel P.

Fixes flat unions to get the base's base members.

The two guards QAPI_TYPES_BUILTIN_STRUCT_DECL and QAPI_TYPES_BUILTIN_CLEANUP_DECL are replaced by just QAPI_TYPES_BUILTIN. Two ugly special cases for simple unions now stand out like sore thumbs: 1. The type tag is named 'type' everywhere, except in generated C, where it's 'kind'. 2. QAPISchema lowers simple unions to semantically equivalent flat unions.

The QAPI code generators work with a syntax tree (nested dictionaries) plus a few symbol tables (also dictionaries) on the side. They have clearly outgrown these simple data structures. There's lots of rummaging around in dictionaries, and information is recomputed on the fly. For the work I'm going to do, I want more clearly defined and more convenient interfaces. Going forward, I also want less coupling between the back-ends and the syntax tree, to make messing with the syntax easier. Create a bunch of classes to represent QAPI schemata. Have the QAPISchema initializer call the parser, then walk the syntax tree to create the new internal representation, and finally perform semantic analysis. Shortcut: the semantic analysis still relies on existing check_exprs() to do the actual semantic checking. All this code needs to move into the classes. Mark as TODO. Simple unions are lowered to flat unions. Flat unions and structs are represented as a more general object type. Catching name collisions in generated code would be nice. Mark as TODO. We generate array types eagerly, even though most of them aren't used. Mark as TODO. Nothing uses the new intermediate representation just yet, thus no change to generated files.

QEMU does have an I/O thread now, that can be interrupted at any time because the VCPU thread runs outside the iothread mutex. Therefore, the kvmppc_timer_hack is obsolete. Remove it. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com> Signed-off-by: NAlexander Graf <agraf@suse.de>

The script used for converting from QEMUMachine had used one DEFINE_MACHINE() per machine registered. In cases where multiple machines are registered from one source file, avoid the excessive generation of module init functions by reverting this unrolling.
