2023-04-24qapi: Fix to reject 'data': 'mumble' in structMarkus Armbruster4-0/+5
A struct's 'data' must be a JSON object defining the struct's members. The QAPI code generator incorrectly accepts a JSON string instead, and then crashes in QAPISchema._make_members() called from ._def_struct_type(). Fix to reject it: factor check_type_implicit() out of check_type_name_or_implicit(), and switch check_struct() to use it instead. Also add a test case.

2021-10-29qapi: New special feature flag "unstable"Markus Armbruster2-2/+10
By convention, names starting with "x-" are experimental. The parts of external interfaces so named may be withdrawn or changed incompatibly in future releases. The naming convention makes unstable interfaces easy to recognize. Promoting something from experimental to stable involves a name change. Client code needs to be updated. Occasionally bothersome. Worse, the convention is not universally observed: * QOM type "input-barrier" has properties "x-origin", "y-origin". Looks accidental, but it's ABI since 4.2. * QOM types "memory-backend-file", "memory-backend-memfd", "memory-backend-ram", and "memory-backend-epc" have a property "x-use-canonical-path-for-ramblock-id" that is documented to be stable despite its name. We could document these exceptions, but documentation helps only humans. We want to recognize "unstable" in code, like "deprecated". So support recognizing it the same way: introduce new special feature flag "unstable". It will be treated specially by the QAPI generator, like the existing feature flag "deprecated", and unlike regular feature flags. This commit updates documentation and prepares tests. The next commit updates the QAPI schema. The remaining patches update the QAPI generator and wire up -compat policy checking. Management applications can then use query-qmp-schema and -compat to manage or guard against use of unstable interfaces the same way as for deprecated interfaces. docs/devel/qapi-code-gen.txt no longer mandates the naming convention. Using it anyway might help writers of programs that aren't full-fledged management applications. Not using it can save us bothersome renames. We'll see how that shakes out.

2021-10-02qapi/parser: remove FIXME comment from _append_body_lineJohn Snow1-1/+1
True, we do not check the validity of this symbol -- but we don't check the validity of definition names during parse, either -- that happens later, during the expr check. I don't want to introduce a dependency on expr.py:check_name_str here and introduce a cycle. Instead, rest assured that a documentation block is required for each definition. This requirement uses the names of each section to ensure that we fulfilled this requirement. e.g., let's say that block-core.json has a comment block for "Snapshot!Info" by accident. We'll see this error message: In file included from ../../qapi/block.json:8: ../../qapi/block-core.json: In struct 'SnapshotInfo': ../../qapi/block-core.json:38: documentation comment is for 'Snapshot!Info' That's a pretty decent error message. Now, let's say that we actually mangle it twice, identically: ../../qapi/block-core.json: In struct 'Snapshot!Info': ../../qapi/block-core.json:38: struct has an invalid name That's also pretty decent. If we forget to fix it in both places, we'll just be back to the first error. Therefore, let's just drop this FIXME and adjust the error message to not imply a more thorough check than is actually performed.

2021-08-26qapi: Fix crash on redefinition with a different conditionMarkus Armbruster1-1/+1
QAPISchema._make_implicit_object_type() asserts that when an implicit object type is used multiple times, @ifcond is the same for all uses. It will be for legitimate uses, i.e. simple union branch wrapper types. A comment explains this. The assertion fails when a command or event is redefined with a different condition. The redefinition is an error, but it's flagged only later. Fixing the assertion would complicate matters further. Not worthwhile, drop it instead. We really need to get rid of simple unions. Tweak test case redefined-event to cover redefinition with a different condition.

2021-07-15qapi: Fix crash on missing enum member nameMarkus Armbruster3-0/+4
New test case enum-dict-no-name.json crashes: $ python3 scripts/qapi-gen.py tests/qapi-schema/enum-dict-no-name.json Traceback (most recent call last): [...] File "/work/armbru/qemu/scripts/qapi/expr.py", line 458, in check_enum member_name = member['name'] KeyError: 'name' Root cause: we try to retrieve member 'name' before we check for missing members. With that fixed, we get the expected error "'data' member misses key 'name'".

2021-05-20qapi/parser: Fix token membership tests when token can be NoneJohn Snow7-0/+6
When the token can be None (EOF), we can't use 'x in "abc"' style membership tests to group types of tokens together, because 'None in "abc"' is a TypeError. Easy enough to fix. (Use a tuple: It's neither a static typing error nor a runtime error to check for None in Tuple[str, ...]) Add tests to prevent a regression. (Note: they cannot be added prior to this fix, as the unhandled stack trace will not match test output in the CI system.)

2021-05-20qapi/parser: enforce all top-level expressions must be dict in _parse()John Snow2-2/+2
Instead of using get_expr nested=False, allow get_expr to always return any expression. In exchange, add a new error message to the top-level parser that explains the semantic error: Top-level expressions must always be JSON objects. This helps mypy understand the rest of this function which assumes that get_expr did indeed return a dict. The exception type changes from QAPIParseError to QAPISemError as a result, and the error message in two tests now changes.
