* qobject: Use 'bool' for qboolEric Blake2015-06-221-3/+3
| | | | | | | | | | | | We require a C99 compiler, so let's use 'bool' instead of 'int' when dealing with boolean values. There are few enough clients to fix them all in one pass.

* json-parser: Accept 'null' in QMPEric Blake2015-05-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We document that in QMP, the client may send any json-value for the optional "id" key, and then return that same value on reply (both success and failures, insofar as the failure happened after parsing the id). [Note that the output may not be identical to the input, as whitespace may change and since we may reorder keys within a json-object, but that this still constitutes the same json-value]. However, we were not handling the JSON literal null, which counts as a json-value per RFC 7159. Also, down the road, given the QAPI schema of {'*foo':'str'} or {'*foo':'ComplexType'}, we could decide to allow the QMP client to pass { "foo":null } instead of the current representation of { } where omitting the key is the only way to get at the default NULL value. Such a change might be useful for argument introspection (if a type in older qemu lacks 'foo' altogether, then an explicit "foo":null probe will force an easily distinguished error message for whether the optional "foo" key is even understood in newer qemu). And if we add default values to optional arguments, allowing an explicit null would be required for getting a NULL value associated with an optional string that has a non-null default. But all that can come at a later day. The 'check-unit' testsuite is enhanced to test that parsing produces the same object as explicitly requesting a reference to the special qnull object. In addition, I tested with: $ ./x86_64-softmmu/qemu-system-x86_64 -qmp stdio -nodefaults {"QMP": {"version": {"qemu": {"micro": 91, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}} {"execute":"qmp_capabilities","id":null} {"return": {}, "id": null} {"id":{"a":null,"b":[1,null]},"execute":"quit"} {"return": {}, "id": {"a": null, "b": [1, null]}} {"timestamp": {"seconds": 1427742379, "microseconds": 423128}, "event": "SHUTDOWN"} Signed-off-by: Eric Blake <eblake@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

* json-parser: fix handling of large whole number valuesMichael Roth2013-05-231-3/+23
| | | | | | | | | | | | | | | Currently our JSON parser assumes that numbers lacking a fractional value are integers and attempts to store them as QInt/int64 values. This breaks in the case where the number overflows/underflows int64 values (which is still valid JSON) Fix this by detecting such cases and using a QFloat to store the value instead.
