2019-09-28qapi: Clean up member name case checkingMarkus Armbruster1-1/+1
QAPISchemaMember.check_clash() checks for member names that map to the same c_name(). Takes care of rejecting duplicate names. It also checks a naming rule: no uppercase in member names. That's a rather odd place to do it. Enforcing naming rules is check_name_str()'s job. qapi-code-gen.txt specifies the name case rule applies to the name as it appears in the schema. check_clash() checks c_name(name) instead. No difference, as c_name() leaves alone case, but unclean. Move the name case check into check_name_str(), less the c_name(). New argument @permit_upper suppresses it. Pass permit_upper=True for definitions (which are not members), and when the member's owner is whitelisted with pragma name-case-whitelist. Bonus: name-case-whitelist now applies to a union's inline base, too. Update qapi/qapi-schema.json pragma to whitelist union CpuInfo instead of CpuInfo's implicit base type's name q_obj_CpuInfo-base.

2019-08-16qapi: Split error.json off common.jsonMarkus Armbruster1-0/+1
In my "build everything" tree, changing a type in qapi/common.json triggers a recompile of some 3600 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). One common dependency is QapiErrorClass: it's used only in in qapi/error.h, which uses nothing else, and is widely included. Move QapiErrorClass from common.json to new error.json. Touching common.json now recompiles only some 2900 objects.

2019-03-11qapi: qapi for audio backendsKővágó, Zoltán1-0/+1
This patch adds structures into qapi to replace the existing configuration structures used by audio backends currently. This qapi will be the base of the -audiodev command line parameter (that replaces the old environment variables based config). This is not a 1:1 translation of the old options, I've tried to make them much more consistent (e.g. almost every backend had an option to specify buffer size, but the name was different for every backend, and some backends required usecs, while some other required frames, samples or bytes). Also tried to reduce the number of abbreviations used by the config keys. Some of the more important changes: * use `in` and `out` instead of `ADC` and `DAC`, as the former is more user friendly imho * moved buffer settings into the global setting area (so it's the same for all backends that support it. Backends that can't change buffer size will simply ignore them). Also using usecs, as it's probably more user friendly than samples or bytes. * try-poll is now an alsa backend specific option (as all other backends currently ignore it) Signed-off-by: Kővágó, Zoltán <DirtY.iCE.hu@gmail.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Message-id: 5461b514dbf3e0bc31b0abb6498a9b3a008c271e.1552083282.git.DirtY.iCE.hu@gmail.com Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2019-02-26authz: add QAuthZList object type for an access control listDaniel P. Berrange1-0/+1
Add a QAuthZList object type that implements the QAuthZ interface. This built-in implementation maintains a trivial access control list with a sequence of match rules and a final default policy. This replicates the functionality currently provided by the qemu_acl module. To create an instance of this object via the QMP monitor, the syntax used would be: { "execute": "object-add", "arguments": { "qom-type": "authz-list", "id": "authz0", "props": { "rules": [ { "match": "fred", "policy": "allow", "format": "exact" }, { "match": "bob", "policy": "allow", "format": "exact" }, { "match": "danb", "policy": "deny", "format": "glob" }, { "match": "dan*", "policy": "allow", "format": "exact" }, ], "policy": "deny" } } } This sets up an authorization rule that allows 'fred', 'bob' and anyone whose name starts with 'dan', except for 'danb'. Everyone unmatched is denied. It is not currently possible to create this via -object, since there is no syntax supported to specify non-scalar properties for objects. This is likely to be addressed by later support for using JSON with -object, or an equivalent approach. In any case the future "authz-listfile" object can be used from the CLI and is likely a better choice, as it allows the ACL to be refreshed automatically on change.

2019-02-18qapi: New module target.jsonMarkus Armbruster1-0/+1
We can't add appropriate target-specific conditionals to misc.json, because that would make all of misc.json unusable in target-independent code. To keep misc.json target-independent, we need to split off target-dependent target.json. This commit doesn't actually split off anything, it merely creates the empty module. The next few patches will move stuff from misc.json there.

2019-02-01vmdk: Implement .bdrv_co_create callbackFam Zheng1-7/+9
This makes VMDK support blockdev-create. The implementation reuses the image creation code in vmdk_co_create_opts which now acceptes a callback pointer to "retrieve" BlockBackend pointers from the caller. This way we separate the logic between file/extent acquisition and initialization. The QAPI command parameters are mostly the same as the old create_opts except the dropped legacy @compat6 switch, which is redundant with @hwversion.

Move qapi-schema.json to qapi/, so it's next to its modules, and all files get generated to qapi/, not just the ones generated for modules. Consistently name the generated files qapi-MODULE.EXT: qmp-commands.[ch] become qapi-commands.[ch], qapi-event.[ch] become qapi-events.[ch], and qmp-introspect.[ch] become qapi-introspect.[ch].
