2024-04-25tests: Remove Ubuntu 20.04 containerThomas Huth2-158/+0

2024-04-25.travis.yml: Do some more testing with ClangThomas Huth1-2/+4
We are doing a lot of cross-compilation tests with GCC in the gitlab-CI already, so we could get some more test coverage by using Clang in the Travis-CI instead. Thus let's switch two additional jobs to use Clang for compilation. Message-ID: <20240320104144.823425-7-thuth@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>
2024-04-25.travis.yml: Update the jobs to Ubuntu 22.04Thomas Huth1-10/+3
According to our support policy, we'll soon drop our official support for Ubuntu 20.04 ("Focal Fossa") in QEMU. Thus we should update the Travis jobs now to a newer release (Ubuntu 22.04 - "Jammy Jellyfish") for future testing. Since all jobs are using this release now, we can drop the entries from the individual jobs and use the global setting again. Reviewed-by: Daniel P.

2024-04-25.travis.yml: Remove the unused UNRELIABLE environment variableThomas Huth1-3/+0
This variable was used to allow jobs to fail without spoiling the overall result. But the required "allow_failures:" hunk has been accidentally removed in commit 9d03f5abed ("travis.yml: Remove the "Release tarball" job"), and it was anyway only useful while we still had the x86 jobs here around that were our main CI jobs.

2024-04-24block/gluster: Remove deprecated RDMA protocol handlingPhilippe Mathieu-Daudé3-42/+2
GlusterFS+RDMA has been deprecated 8 years ago in commit 0552ff2465 ("block/gluster: deprecate rdma support"): gluster volfile server fetch happens through unix and/or tcp, it doesn't support volfile fetch over rdma. The rdma code may actually mislead, so to make sure things do not break, for now we fallback to tcp when requested for rdma, with a warning. If you are wondering how this worked all these days, its the gluster libgfapi code which handles anything other than unix transport as socket/tcp, sad but true. Besides, the whole RDMA subsystem was deprecated in commit e9a54265f5 ("hw/rdma: Deprecate the pvrdma device and the rdma subsystem") released in v8.2.

2024-04-24qapi/parser: demote QAPIExpression to Dict[str, Any]John Snow1-1/+2
Dict[str, object] is a stricter type, but with the way that code is currently arranged, it is infeasible to enforce this strictness. In particular, although expr.py's entire raison d'être is normalization and type-checking of QAPI Expressions, that type information is not "remembered" in any meaningful way by mypy because each individual expression is not downcast to a specific expression type that holds all the details of each expression's unique form. As a result, all of the code in schema.py that deals with actually creating type-safe specialized structures has no guarantee (myopically) that the data it is being passed is correct. There are two ways to solve this: (1) Re-assert that the incoming data is in the shape we expect it to be, or (2) Disable type checking for this data. (1) is appealing to my sense of strictness, but I gotta concede that it is asinine to re-check the shape of a QAPIExpression in schema.py when expr.py has just completed that work at length. The duplication of code and the nightmare thought of needing to update both locations if and when we change the shape of these structures makes me extremely reluctant to go down this route. (2) allows us the chance to miss updating types in the case that types are updated in expr.py, but it *is* an awful lot simpler and, importantly, gets us closer to type checking schema.py *at all*. Something is better than nothing, I'd argue. So, do the simpler dumber thing and worry about future strictness improvements later.

2024-04-24qapi/schema: assert inner type of QAPISchemaVariants in check_clash()John Snow1-1/+4
QAPISchemaVariant's "variants" field is typed as List[QAPISchemaVariant], where the typing for QAPISchemaVariant allows its type field to be any QAPISchemaType. However, QAPISchemaVariant expects that all of its variants contain the narrower QAPISchemaObjectType. This relationship is enforced at runtime in QAPISchemaVariants.check(). This relationship is not embedded in the type system though, so QAPISchemaVariants.check_clash() needs to re-assert this property in order to call QAPISchemaVariant.type.check_clash().

There are two related changes here: (1) We need to perform type narrowing for resolving the type of tag_member during check(), and (2) tag_member is a delayed initialization field, but we can hide it behind a property that raises an Exception if it's called too early. This simplifies the typing in quite a few places and avoids needing to assert that the "tag_member is not None" at a dozen callsites, which can be confusing and suggest the wrong thing to a drive-by contributor.

2024-04-24qapi/schema: Don't initialize "members" with `None`John Snow1-5/+7
Declare, but don't initialize the "members" field with type List[QAPISchemaObjectTypeMember]. This simplifies the typing from what would otherwise be Optional[List[T]] to merely List[T]. This removes the need to add assertions to several callsites that this value is not None - which it never will be after the delayed initialization in check() anyway. The type declaration without initialization trick will cause accidental uses of this field prior to full initialization to raise an AttributeError. (Note that it is valid to have an empty members list, see the internal q_empty object as an example. For this reason, we cannot use the empty list as a replacement test for full initialization and instead rely on the _checked/_check_complete fields.)

2024-04-24qapi/schema: assert resolve_type has 'info' and 'what' args on errorJohn Snow1-0/+1
resolve_type() is generally used to resolve configuration-provided type names into type objects, and generally requires valid 'info' and 'what' parameters. In some cases, such as with QAPISchemaArrayType.check(), resolve_type may be used to resolve built-in types and as such will not have an 'info' argument, but also must not fail in this scenario. Use an assertion to sate mypy that we will indeed have 'info' and 'what' parameters for the error pathway in resolve_type. Note: there are only three callsites to resolve_type at present where "info" is perceived by mypy to be possibly None: 1) QAPISchemaArrayType.check() 2) QAPISchemaObjectTypeMember.check() 3) QAPISchemaEvent.check() Of those three, only the first actually ever passes None; the other two are limited by their base class initializers which accept info=None, but neither subclass actually use a None value in practice, currently.

2024-04-24qapi/schema: declare type for QAPISchemaArrayType.element_typeJohn Snow1-1/+1
A QAPISchemaArrayType's element type gets resolved only during .check(). We have QAPISchemaArrayType.__init__() initialize self.element_type = None, and .check() assign the actual type. Using .element_type before .check() is wrong, and hopefully crashes due to the value being None. Works. However, it makes for awkward typing. With .element_type: Optional[QAPISchemaType], mypy is of course unable to see that it's None before .check(), and a QAPISchemaType after. To help it over the hump, we'd have to assert self.element_type is not None before all the (valid) uses. The assertion catches invalid uses, but only at run time; mypy can't flag them. Instead, declare .element_type in .__init__() as QAPISchemaType *without* initializing it. Using .element_type before .check() now certainly crashes, which is an improvement. Mypy still can't flag invalid uses, but that's okay.

2024-04-24qapi: create QAPISchemaDefinitionJohn Snow1-58/+78
Include entities don't have names, but we generally expect "entities" to have names. Reclassify all entities with names as *definitions*, leaving the nameless include entities as QAPISchemaEntity instances. This is primarily to help simplify typing around expectations of what callers expect for properties of an "entity".
