The inputs and expected outputs for the tests are encoded using a
schema. Each property present in the schema forms a testcase; the
expected outputs for each language are stored in each property's
`Language` field with the language name "test". Expected outputs can be
regenerated using `PULUMI_ACCEPT`.
Rather than duplicating the list of tests and codegen driver across each
SDK, move its definition into `pkg/codegen/internal/test`. This has a
few notable benefits:
- All SDK code generators will be tested against each test. Though some
tests may exercise a particular code generator more than others, the
extra coverage will be generally beneficial.
- Adding a new test is simpler, as only a single file needs to be
changed.
- All SDKs now honor the `PULUMI_ACCEPT` environment variable for
updating baselines.
- Codegen tests now validate all generated files instead of only a
particular subset.
These changes support arbitrary combinations of input + plain types
within a schema. Handling plain types at the property level was not
sufficient to support such combinations. Reifying these types
required updating quite a bit of code. This is likely to have caused
some temporary complications, but should eventually lead to
substantial simplification in the SDK and program code generators.
With the new design, input and optional types are explicit in the schema
type system. Optionals will only appear at the outermost level of a type
(i.e. Input<Optional<>>, Array<Optional<>>, etc. will not occur). In
addition to explicit input types, each object type now has a "plain"
shape and an "input" shape. The former uses only plain types; the latter
uses input shapes wherever a plain type is not specified. Plain types
are indicated in the schema by setting the "plain" property of a type spec
to true.
In Go, resource types are modeled as pointers, but there were cases where the type was not being emitted as a pointer, leading to panics and marshaling errors in programs. Additionally, array and map values that are external references were being emitted as pointers, but only resources should be pointers (not types), regardless of whether the resource type is external or local.
This change adds schema and codegen support for plain properties which
are emitted typed as the plain type rather than wrapped as an `Input`.
Plain properties require a prompt value and do not accept a value that
is `Output`.
Generate ResourcePackage and ResourceModule implementations and
registrations. A ResourcePackage is generated for any module that
includes a provider resource (which should be the root module only), and
a ResourceModule is generated for any module that includes a resource.
And add version info to Python registrations.
