Add support for creating instances of resources in Python using a
`<Resource>Args` class. This capability aligns with how args are passed
to resources in all the other language SDKs and the separate object bag
allows the properties to be manipulated/validated/passed-around before
creating the resource.
We've been emitting calls to `New<Resource>` for resource registrations
in Go, passing `nil` for args. However, some of those `New<Resource>`
functions actually check for `nil` args and return an error if the
resource has required arguments.
At first, I was looking for a way to check inside `New<Resource>` if
the `URN` option was specified and in that case not error on
`nil` args (like we do in other languages), but we don't provide a way
to access the resource option values outside the Go SDK), so I don't
think there is a way to do it this way for Go.
So instead, this change updates the registration code to call
`ctx.RegisterResource` directly instead of `New<Resource>`, where we can
pass a `nil` args.
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`.
We currently include `version.txt` in the package via `<Content Include="version.txt">`. This places the file in the NuGet package in two locations: the `content` directory and `contentFiles`.
We want the file to be in `content` because this is where the Pulumi .NET Language host looks for the file when determining a program's required plugins.
However, having the file in `contentFiles` is problematic. For packages that reference other Pulumi resource packages (e.g. for multi-lang components), referenced `contentFiles` are included in the package by default. This means another package's `version.txt` will be included and used over the current project's `version.txt`. For example, if a multi-lang component package `Pulumi.Xyz` references `Pulumi.Aws`, the `version.txt` from `Pulumi.Aws` will be used in `Pulumi.Xyz` package rather than the intended `version.txt` for `Pulumi.Xyz`.
To address this, stop including `version.txt` in `contentFiles`. We do this by changing the `<Content Include="version.txt" />` to `<None Include="version.txt" Pack="True" PackagePath="content" />` in the project file. This ensures the file will still be included in the package in the `content` dir (where the Pulumi .NET language host expects to find it), but doesn't include the file in `contentFiles` which would cause it to be used in other packages that reference the package.
Further, when generating `<PackageReference>`s for packages that start with "Pulumi.", include an additional `ExcludeAssets="contentFiles"` attribute to prevent the package's `contentFiles` from being included.
This new optional file can be used to include additional metadata about the provider plugin (such as version and custom server URL), which the Python language host will use when determining a program's required plugins.
This change fixes the codegen to emit the file in the correct location (inside the package dir). Note: Providers need to opt-in to emitting this file via a schema option (because it requires some Makefile changes to insert the version in the file) and we haven't done that with any of our providers yet.
The schema specifies supported environment variables
for Provider inputs, but these are not currently reflected
in the generated docs. This change adds any supported
environment variables to the input property comment
field on Provider resources.
