The latest version of the core Pulumi SDK contains a decorator, `@deprecated`, that is used when generating SDK code in order to signify deprecated properties in a way that can be recognised by other SDK code. This is useful when writing generic Python code that e.g. traverses class properties without triggering deprecation warnings for those not explicitly mentioned in user code. The [original pull request](https://github.com/pulumi/pulumi/pull/16400) has more details. Alas, we can't rely on the fact that a user will upgrade _both_ a particular (generated) provider SDK and the core Pulumi SDK at the same time. Thus, it's entirely possible that a user bumps their version of (say) `pulumi_aws`, whilst leaving their `pulumi` library at the same (compatible, according to specified bounds) version. In doing so they'd hit errors when the new SDK tried to import the `@deprecated` decorator, which doesn't exist in the old core SDK. This commit thus fixes this by altering code generation so that each SDK receives its own inlined copy of the `@deprecated` decorator, which it can reference regardless of the version of the core SDK. This decorator applies the same `_pulumi_deprecated_callable` tag to functions it decorates, which a sufficiently modern SDK will recognise to avoid triggering e.g. https://github.com/pulumi/pulumi/issues/15894. Later on, we can hopefully find a way to avoid doing this and use only a version of `@deprecated` specified in the core SDK. Codegen tests have been updated and the inlined decorator has manually been tested using the AWS Classic SDK. Addresses https://github.com/pulumi/pulumi/pull/16400#discussion_r1646562455 |
