The previous commit demonstrated that the generator had several
flaws with less-than-perfect enums:
- an enum that listed the same string twice (or two variant
strings that map to the same C enumerator) ended up generating
an invalid C enum
- because the generator adds a _MAX terminator to each enum,
the use of an enum member 'max' can also cause this clash
- if an enum omits 'data', the generator left a python stack
trace rather than a graceful message
- an enum that used a non-array 'data' was silently accepted by
the parser
- an enum that used non-string members in the 'data' member
was silently accepted by the parser
Add check_enum to cover these situations, and update testcases
to match. While valid .json files won't trigger any of these
cases, we might as well be nicer to developers that make a typo
while trying to add new QAPI code.
Backports commit cf3935907b5df16f667d54ad6761c7e937dcf425 from qemu
We were missing the 'size' builtin type (which means that QAPI using
[ 'size' ] would fail to compile).
Backports commit cb17f79eef0d161e81ac457e4c1f124405be2a18 from qemu
There was some redundancy between builtin_types[] and
builtin_type_qtypes{}. Merge them into one.
Backports commit b52c4b9cf0bbafdf8cede4ea1f62770d86815718 from qemu
Defaulting a parameter to True, then having all callers omit or
pass an explicit True for that parameter, is pointless. Looks
like it has been dead since introduction in commit 06d64c6, more
than 4 years ago.
Backports commit 6540e9f35bfeea2baf4509745516172070dca412 from qemu
No backend was setting an error when ending the visit of a list or
implicit struct, or when moving to the next list node. Make the
callers a bit easier to follow by making this a part of the contract,
and removing the errp argument - callers can then unconditionally end
an object as part of cleanup without having to think about whether a
second error is dominated by a first, because there is no second
error.
A later patch will then tackle the larger task of splitting
visit_end_struct(), which can indeed set an error.
