We currently emit array types as `List[T]` for Python, but `List[T]` is invariant, which causes type checkers like mypy to produce errors when values like `["foo", "bar"]` are passed as args typed as `List[pulumi.Input[str]]` (since `Input[str]` is an alias for `Union[T, Awaitable[T], Output[T]]`. To address this, we should move to using [`Sequence[T]`](https://docs.python.org/3/library/typing.html#typing.Sequence) which is covariant, and does not have this problem.
We actually already do this for `Dict` vs. `Mapping`, emitting map types as `Mapping[str, T]` rather than `Dict[str, T]` because `Mapping[str, T]` is covariant for the value. This change makes us consistent for array types.
These are the SDK changes necessary to support `Sequence[T]`.
These changes add initial support for the construction of remote
components. For now, this support is limited to the NodeJS SDK;
follow-up changes will implement support for the other SDKs.
Remote components are component resources that are constructed and
managed by plugins rather than by Pulumi programs. In this sense, they
are a bit like cloud resources, and are supported by the same
distribution and plugin loading mechanisms and described by the same
schema system.
The construction of a remote component is initiated by a
`RegisterResourceRequest` with the new `remote` field set to `true`.
When the resource monitor receives such a request, it loads the plugin
that implements the component resource and calls the `Construct`
method added to the resource provider interface as part of these
changes. This method accepts the information necessary to construct the
component and its children: the component's name, type, resource
options, inputs, and input dependencies. It is responsible for
dispatching to the appropriate component factory to create the
component, then returning its URN, resolved output properties, and
output property dependencies. The dependency information is necessary to
support features such as delete-before-replace, which rely on precise
dependency information for custom resources.
These changes also add initial support for more conveniently
implementing resource providers in NodeJS. The interface used to
implement such a provider is similar to the dynamic provider interface
(and may be unified with that interface in the future).
An example of a NodeJS program constructing a remote component resource
also implemented in NodeJS can be found in
`tests/construct_component/nodejs`.
This is the core of #2430.
Pylint currently reports `E1101: Instance of 'Bucket' has no 'id' member (no-member)` on lines in Pulumi Python programs like:
```python
pulumi.export('bucket_name', bucket.id)
```
Here's a description of this message from http://pylint-messages.wikidot.com/messages:e1101:
> Used when an object (variable, function, …) is accessed for a non-existent member.
>
> False positives: This message may report object members that are created dynamically, but exist at the time they are accessed.
This appears to be a false positive case: `id` isn't set in the constructor (it's set later in `register_resource`) and Pylint isn't able to figure this out statically. `urn` has the same problem. (Oddly, Pylint doesn't complain when accessing other resource output properties).
This change refactors `register_resource` so that `id` and `urn` can be assigned in the resource's constructor, so that Pylint can see it being assigned. The change also does the same with `read_resource`.
This class was available in the pulumi.resource module, but was not exported from the core `pulumi` module as intended for all public APIs at this level.
The previous attempt to allow this didn't actually allow it, so this is
take two. As part of the previous attempt, I thought after tweaking the
test I had observed the test failing, and then succeeding after making
the product changes, but I must have been mistaken.
It turns out that our existing mocks tests weren't running at all
because of a missing `__init__.py` file. Once the missing `__init__.py`
is added, the tests run, but other tests ("test mode" tests) fail
because the code that creates the mocks and resources will run during
test discovery, and setting the mocks modifies global state.
To address the test issue, I've moved the mocks tests into their own
`test_with_mocks` package that can be run separately from other tests.
And addressed the original issue, by creating a root Stack resource if
one isn't already present when the mocks are set.
This change allows importing modules with calls to `pulumi.export` in unit tests. Previously, you'd have to structure the Python program in a way that avoids the `pulumi.export` from being called from unit tests.
* [sdk/python] Improve `ResoruceOptions.merge` type
The implementation correctly handles `None` inputs, so the type should allow these as well.
* Add CHANGELOG
The initial config represents any config that was specified programmatically to the Policy Pack, for Policy Packs that support programmatic configuration like AWSGuard.
It's not entirely clear why gRPC doesn't already report these cleanly as unimplemented, but for now we'll explicitly implement them to avoid any spurious warnings.
Fixes#4028.
The original version of this code caused inconsistencies in the event
loop associated with a given thread. These changes elimintate the event
loop shenanigans the mocks were trying to play by updating _sync_await
to create an event loop if none exists in the current thread.
It's possible that this will cause problems if the tests run on a
different thread than the original program, as the tests are likely to
end up waiting on outputs created by the program, which is not supported
in Python.
Also adds test coverage of the mocking/testing support in Python.
These changes add support for mocking the resource monitor to the NodeJS
and Python SDKs. The proposed mock interface is a simplified version of
the standard resource monitor that allows an end-user to replace the
usual implementations of ReadResource/RegisterResource and Invoke with
their own. This can be used in unit tests to allow for precise control
of resource outputs and invoke results.
These changes add a new method to the resource provider gRPC interface,
`GetSchema`, that allows consumers of these providers to extract
JSON-serialized schema information for the provider's types, resources,
and functions.
Set an option to increase the memory limit on protobuf
parsing so that we can handle larger gRPC payloads.

The provider plugin protocol is to write a port number followed by `\n`. We must guarantee we do that even on Windows, so must avoid Python `print` statements which implicitly rewrite newlines to platform specific character sequences.
Fixes#3807.
PEP 561 specifies that packages which contain either inline type hints
or type stubs should indicate their support for type hints via
including a file named `py.typed` in the root of the package. Since
Pulumi already includes inline type hints, adding `py.typed` to the
Python SDK simply allows these hints to be used by mypy.
