Implement GetRequiredPlugins for Python, which determines the plugins
required by the program.
Also, if the `virtualenv` runtime option is set, and the specified
virtual directory is missing or empty, automatically create it and
install dependencies into it.
There are two significant changes in this commit: one to the way
resource packages/modules are stored and retrieved, and one to resource
ref deserialization in the face of missing resource packages/modules.
Resource packages and modules no longer require an exact version match
during deserialization. Instead, the newest compatible version of the
package or module is selected. If no version was specified, the newest
version of the package or module will be chosen. As a special case, a
package or module that has no version will always be treated as the best
version for that package or module.
If a resource package or module is not found when attempting to
deserialize a resource reference, the SDK no longer emits an error, and
instead deserializes the reference as its URN or ID (if present). This
accommodates providers that have not yet been updated to include the
appropriate factory registrations.
- Differentiate between resource references that have no ID (i.e. because
the referenced resource is not a CustomResource) and resource references
that have IDs that are not known. This is necessary for proper
backwards-compatible serialization of resource references.
- Fix the key that stores a resource reference's package version in the
.NET, NodeJS, and Python SDKs.
- Ensure that the resource monitor's marshalling/unmarshalling of inputs
and outputs to/from calls to `Construct` retain resource references as
appropriate.
- Fix serialization behavior for resources -> resource references in the
Go SDK: if a resource's ID is unknown, it should still be serialized
as a resource reference, albeit a reference with an unknown ID.
Just what it says on the tin.
The SDK code generator will be updated to use the new `urn`
resource option inside of each module's implementation of
`ResourceModule.construct`.

Just what it says on the tin. This is implemented by changing the
`GetPackageConfig` method of `ConfigSource` to return a `PropertyMap`
and ensuring that any secret config is represented by a `Secret`.
This is necessary due to the way we've factored the libraries imported
by users into modules. The primary alternative is to ensure that each
child module imports the root module for a package and registers itself
with that package where necessary to prevent circular dependencies. This
simplifies the core SDKs slightly at the cost of greater complications
in the generated SDKs; the approach taken by these changes seems like a
more maintainable option.
Contributes to #2430.

Resources are serialized as their URN, ID, and package version. Each
Pulumi package is expected to register itself with the SDK. The package
will be invoked to construct appropriate instances of rehydrated
resources. Packages are distinguished by their name and their version.
This is the foundation of cross-process resources.

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.
A recent change to output deserialization resulted in secrets being returned unwrapped. This change addresses the regression, ensuring any unwrapped secret values are rewrapped before being returned.
We recently made a change to the Python codegen to emit `int` type annotations, instead of `float`, for properties that are typed as `schema.IntType`.
But the number values that come back from protobuf structs are always floats (like JSON), so we need to cast the values intended to be integers to `int`.
When installing a plugin, if it contains a `PulumiPlugin.yaml` file with a `runtime` value of `nodejs` or `python`, install dependencies for the plugin.
For Node.js, `npm install` is run (or `yarn install` if `PULUMI_PREFER_YARN` is set).
For Python, a virtual environment is created and deps installed into it.
Non-string provider inputs must be projected as JSON formatted strings. The current codegen simply calls `json.dumps` for such properties, but this does not work for the new input types, which aren't JSON serializable.
This commit adds a new `pulumi.runtime.to_json` utility function to the core SDK, which is capable of serializing both raw dicts and input types as JSON. The codegen will be updated to make use of this new function rather than `json.dumps`.
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.
Update pip, setuptools, and wheel in the virtual environment before installing dependencies as recommended by the Python documentation. This should help avoid failures when only source distributions are available for a package and pip attempts to build a wheel locally.
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`.
Automatically create a virtual environment and install dependencies in it with `pulumi new` and `pulumi policy new` for Python templates.
This will save a new `virtualenv` runtime option in `Pulumi.yaml` (`PulumiPolicy.yaml` for policy packs):
```yaml
runtime:
name: python
options:
virtualenv: venv
```
`virtualenv` is the path to a virtual environment that Pulumi will use when running `python` commands.
Existing projects are unaffected and can opt-in to using this by setting `virtualenv`, otherwise, they'll continue to work as-is.
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.
