2018-04-26checkpatch: Add xendevicemodel_handle to the list of typesIan Jackson
This avoids checkpatch misparsing (as statements) long function definitions or declarations, which sometimes start with constructs like this: static inline int xendevicemodel_relocate_memory( xendevicemodel_handle *dmod, domid_t domid, ... The type xendevicemodel_handle does not conform to Qemu CODING_STYLE, which would suggest CamelCase. However, it is a type defined by the Xen Project in xen.git. It would be possible to introduce a typedef to allow the qemu code to refer to it by a differently-spelled name, but that would obfuscate more than it would clarify.

2018-03-19qapi: introduce new cmd option "allow-oob"Peter Xu
Here "oob" stands for "Out-Of-Band". When "allow-oob" is set, it means the command allows out-of-band execution. The "oob" idea is proposed by Markus Armbruster in following thread: https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg02057.html This new "allow-oob" boolean will be exposed by "query-qmp-schema" as well for command entries, so that QMP clients can know which commands can be used in out-of-band calls. For example the command "migrate" originally looks like: {"name": "migrate", "ret-type": "17", "meta-type": "command", "arg-type": "86"} And it'll be changed into: {"name": "migrate", "ret-type": "17", "allow-oob": false, "meta-type": "command", "arg-type": "86"} This patch only provides the QMP interface level changes. It does not contain the real out-of-band execution implementation yet.

Sometimes, we want to refer to really long URLs, but checkpatch balks, and we have to manually bypass the check. URL shorteners may be nice at reducing long links, but it's hard to guarantee the shortened link will live as long as the real target, and it is also nice to see the original target without having to load the shortened URL through a browser. So exempt a line containing only a URL from the long-line syntax check.

2018-03-12simpletrace: fix timestamp argument typeStefan Hajnoczi
The timestamp argument to a trace event method is documented as follows: The method can also take a timestamp argument before the trace event arguments: def runstate_set(self, timestamp, new_state): ... Timestamps have the uint64_t type and are in nanoseconds. In reality methods with a timestamp argument actually receive a tuple like (123456789,) as the timestamp argument. This is due to a bug in simpletrace.py. This patch unpacks the tuple so that methods receive the correct timestamp argument type.

2018-03-12log-for-trace.h: Split out parts of log.h used by trace.hPeter Maydell
A persistent build problem we see is where a source file accidentally omits the #include of log.h. This slips through local developer testing because if you configure with the default (log) trace backend trace.h will pull in log.h for you. Compilation fails only if some other backend is selected. To make this error cause a compile failure regardless of the configured trace backend, split out the parts of log.h that trace.h requires into a new log-for-trace.h header. Since almost all manual uses of the log.h functions will use constants or functions which aren't in log-for-trace.h, this will let us catch missing #include "qemu/log.h" more consistently.

2018-03-02Include less of the generated modular QAPI headersMarkus Armbruster
In my "build everything" tree, a change to the types in qapi-schema.json triggers a recompile of about 4800 out of 5100 objects. The previous commit split up qmp-commands.h, qmp-event.h, qmp-visit.h, qapi-types.h. Each of these headers still includes all its shards. Reduce compile time by including just the shards we actually need. To illustrate the benefits: adding a type to qapi/migration.json now recompiles some 2300 instead of 4800 objects. The next commit will improve it further.

2018-03-02qapi: Generate separate .h, .c for each moduleMarkus Armbruster
Our qapi-schema.json is composed of modules connected by include directives, but the generated code is monolithic all the same: one qapi-types.h with all the types, one qapi-visit.h with all the visitors, and so forth. These monolithic headers get included all over the place. In my "build everything" tree, adding a QAPI type recompiles about 4800 out of 5100 objects. We wouldn't write such monolithic headers by hand. It stands to reason that we shouldn't generate them, either. Split up generated qapi-types.h to mirror the schema's modular structure: one header per module. Name the main module's header qapi-types.h, and sub-module D/B.json's header D/qapi-types-B.h. Mirror the schema's includes in the headers, so that qapi-types.h gets you everything exactly as before. If you need less, you can include one or more of the sub-module headers. To be exploited shortly. Split up qapi-types.c, qapi-visit.h, qapi-visit.c, qmp-commands.h, qmp-commands.c, qapi-event.h, qapi-event.c the same way. qmp-introspect.h, qmp-introspect.c and qapi.texi remain monolithic. The split of qmp-commands.c duplicates static helper function qmp_marshal_output_str() in qapi-commands-char.c and qapi-commands-misc.c. This happens when commands returning the same type occur in multiple modules. Not worth avoiding. Since I'm going to rename qapi-event.[ch] to qapi-events.[ch], and qmp-commands.[ch] to qapi-commands.[ch], name the shards that way already, to reduce churn. This requires temporary hacks in commands.py and events.py. Similarly, c_name() must temporarily be taught to munge '/' in common.py. They'll go away with the rename.

2018-03-02qapi/types qapi/visit: Generate built-in stuff into separate filesMarkus Armbruster
Linking code from multiple separate QAPI schemata into the same program is possible, but involves some weirdness around built-in types: * We generate code for built-in types into .c only with option --builtins. The user is responsible for generating code for exactly one QAPI schema per program with --builtins. * We generate code for built-in types into .h regardless of --builtins, but guarded by #ifndef QAPI_VISIT_BUILTIN. Because all copies of this code are exactly the same, including any combination of these headers works. Replace this contraption by something more conventional: generate code for built-in types into their very own files: qapi-builtin-types.c, qapi-builtin-visit.c, qapi-builtin-types.h, qapi-builtin-visit.h, but only with --builtins. Obey --output-dir, but ignore --prefix for them. Make qapi-types.h include qapi-builtin-types.h. With multiple schemata you now have multiple qapi-types.[ch], but only one qapi-builtin-types.[ch]. Same for qapi-visit.[ch] and qapi-builtin-visit.[ch]. Bonus: if all you need is built-in stuff, you can include a much smaller header. To be exploited shortly.

2018-03-02qapi: Record 'include' directives in intermediate representationMarkus Armbruster
The include directive permits modular QAPI schemata, but the generated code is monolithic all the same. To permit generating modular code, the front end needs to pass more information on inclusions to the back ends. The commit before last added the necessary information to the parse tree. This commit adds it to the intermediate representation and its QAPISchemaVisitor. A later commit will use this to to generate modular code. New entity QAPISchemaInclude represents inclusions. Call new visitor method visit_include() for it, so visitors can see the sub-modules a module includes. Note that unlike other entities, QAPISchemaInclude has no name, and is therefore not added to entity_dict. New QAPISchemaEntity attribute @module names the entity's source file. Call new visitor method visit_module() when it changes during a visit, so visitors can keep track of the module being visited.
