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.
More testing has found further issues with incorrect attribute shapes
generated by tf2pulumi. This knob will allow us to continue to generate
examples until those bugs are fixed.
Add an option to allow missing object properties. This will prevent us
from losing examples once resource typechecking is fixed (it is
currently unintentionally disabled because the resource inputs object
type has an unexpected shape).
These changes add support for provider-side previews of create and
update operations, which allows resource providers to supply output
property values for resources that are being created or updated during a
preview.
If a plugin supports provider-side preview, its create/update methods
will be invoked during previews with the `preview` property set to true.
It is the responsibility of the provider to fill in any output
properties that are known before returning. It is a best practice for
providers to only fill in property values that are guaranteed to be
identical if the preview were instead an update (i.e. only those output
properties whose values can be conclusively determined without
actually performing the create/update operation should be populated).
Providers that support previews must accept unknown values in their
create and update methods.
If a plugin does not support provider-side preview, the inputs to a
create or update operation will be propagated to the outputs as they are
today.
Fixes#4992.
Instead of requiring a plugin host for package loading in the HCL2
binder, define a much narrower interface that exposes the ability to
fetch the schema for a package at a specific version. This interface is
defined in the schema package, which also exposes a caching loader that
is backed by provider plugins.
These changes also add some convenience methods to `*schema.Package` for
fast access to particular resources and functions.
Related to #1635.
If we are generating code into an async context (e.g. an async main),
await calls to invoke rather than leaving them as promises. This results
in more idiomatic code withing such contexts.
If a single process is going to bind and generate multiple programs, it
is useful to be able to cache package schemas in order to avoid the
(large) overhead of deserializing schemas multiple times.
Some property names are mapped from their `camelCase` Pulumi name to a
`snake_case` Python name. This mapping is irregular, and only occurs for
resources properties and function calls.
Note that there's still more work to do here: this only fixes names on
the output side; the input side is still broken for nested resource
proprerties and function calls.
The underlying design--annotated types in `hcl2/model`--may need some
additional work in the future, but I _believe_ it's good enough for now.

* Fix the nullability of config type properties in C# codegen (#4379)
Pulumi HCL2 IR:
- Add support for invokes
- Add support for resource options, incl. ranged resources
- Allow the apply rewriter to ignore promise-typed values
- Add tests for the binder
- Add support functions for TF: entries and range
NodeJS codegen:
- Simplify for expression codegen
- Add support for invoke codegen
- Add support for entries and range functions
- Add tests
Python codegen:
- Implement codegen for most expression types
- Add support for invoke codegen
- Add tests
- config variables are now specified as `config <name> <type>`
- output variables are now specified as `output <name> <type>`
- apply arguments are assigned better names by the apply rewriters
These changes add preliminary (read: incomplete) support for
representing Pulumi programs using HCL2. Language-specific code
generators can use this representation as a basis for understanding the
semantics of a Pulumi program.
