* Implement first-class providers for Python
First-class providers are an explicit projection of providers themselves
into Pulumi programs. For the most post, providers are just regular
resources, but the addition of providers to the fray (and the ability of
resources to be constructed by providers in the same program) requires
some changes to the Python resource model.
A summary of the changes:
1. Added ProviderResource, a custom resource that is the base class of
all providers.
2. ResourceOptions now has 'provider' and 'providers' fields.
'provider', when passed to a custom resource, allows users to override
the provider that is used to construct a resource to an instance of a
ProviderResource. 'providers', when passed to a component resource,
allows users to override providers used to construct children of the
component resource.
3. 'protect', 'providers', and 'provider' are all now inherited from
a resource's parent if they aren't specified in the child.
This commit adds the requisite code for the above changes and, in
addition, adds a number of new tests that exercise them and related code
paths.
* Rebase against master
This is something of a quick hack to work around the limitations that
are at the root of #2310. In short, `StackReference` resources do not
change during a update because their inputs have not changed and we do
not refresh resources as part of the update by default. We want
`StackReference` to remain a resource for myriad reasons (not the least
of which is to avoid a breaking change), but it does seem correct for it
to refresh its state during each update. Because there is no actual CRUD
operation associated with a `StackReferece`, we can obtain this behavior
by changing the implementation of its ctor in the various SDKs s.t. its
options bag always contains an appropriate `id`, thus indicating a
`Read`.
Fixes#2310.
* Add 'Output.all' combinator for Python
Output.all is a useful combinator that we already have in Node that
allows the composition of a list of outputs into an output of a list.
This is very useful when authoring components and its lack of presence
in Python was an oversight.
This commit adds 'Output.all' and 'Output.from_input', adding tests and
documentation for each.
* start unwrap
* Add functionality and test for nested inputs
Previously, we assumed that the dynamic provider was located in
`./node_modules/@pulumi/pulumi/../` which is correct in the majority
of cases. However, tools like lerna or yarn workspaces (or custom
workflows) allow the node_modules folder to be located elsewhere on
disk, and node will still find it because of its algorithm for module
resolution.
So, do what we do in the language host itself, first launch node and
ask it to tell us where it resolves a require statement to on disk and
then launch node against that script.
Fixes#2261
If a custom resource has explicitly specified a provider, add that
provider to the resource's provider map under the resource's package.
This allows children of the custom resource to inherit the resource's
provider.
Fixes#2262.
The langhost shares its standard out and standard error with the
language executor that it is used (python/nodejs), so we must be sure to
flush our stdout and stderr before reporting a Run failure to the
engine.
'python' is not usually symlinked to 'python3' on most distros unless
you are already running in a virtual environment. Launching 'python3'
explicitly ensures that we will either launch the program successfully
or immediately fail, instead of launching the program with Python 2 and
failing with syntax errors at runtime.
This commit also emits an error message asking users to install Python
3.6 or later if we failed to find the 'python3' executable.
This changes the input type for dependsOn from simply
`Resource[] | Resource` to `Input<Input<Resource>[]> | Input<Resource>`.
This permits `Output<Resource>`s, etc in addition to
`Promise<Resource>`s. The logic for dynamically unpicking the right
types and recursing through the data structures isn't straightforward,
but I've written a test for all of the interesting permutations.
This fixespulumi/pulumi#991.
These changes add a new resource to the Pulumi SDK,
`pulumi.StackReference`, that represents a reference to another stack.
This resource has an output property, `outputs`, that contains the
complete set of outputs for the referenced stack. The Pulumi account
performing the deployment that creates a `StackReference` must have
access to the referenced stack or the call will fail.
This resource is implemented by a builtin provider managed by the engine.
This provider will be used for any custom resources and invokes inside
the `pulumi:pulumi` module. Currently this provider supports only the
`pulumi:pulumi:StackReference` resource.
Fixes#109.
* Fix, formalize and add tests for property rewrites
The Python SDK provides two hooks for resources to override how their
properties are communicated to and from the engine. The code that
performs this transformation is subtle and, before this commit, subtly
incorrect.
This commit adds a test that verifies that the SDK correctly transforms
properties recursively according to the two transformation hooks, while
also fixing a smattering of test issues encountered when adding the new
test.
* CR feedback
We run the same suite of changes that we did on gometalinter. This
ended up catching a few new issues, some of which were addressed and
some of which were baselined.
- Remove the forked copy of the toolset
- Stop installing `pipenv` in sdk/python/Makefile
After this, we'll require that you already have `pipenv` present
before building.
* Implement RegisterResourceOutputs for Python 3
RegisterResourceOutputs allows Python 3 programs to export stack outputs
and export outputs off of component resources (which, under the hood,
are the same thing).
Adds a new integration test for stack outputs for Python programs, as
well as add a langhost test for register resource outputs.
Fixespulumi/pulumi#2163
* CR: Rename stack_output -> export
Fix integration tests that hardcoded paths to stack_outputs
* Fix one more reference to stack_outputs
future_input tests that it's possible to use coroutines as inputs to
Pulumi resources. resource_thens tests that it's possible to use outputs
to chain resource inputs and outputs together and that the SDK reports
correct dependencies to the engine.
This PR also fixes two bugs exposed by the new tests: first, coroutines
needed to be scheduled before awaiting (otherwise we'd deadlock) and
Nones in maps needed to be ignored when serializing and deserializing.
1. Add support for first-class providers
2. Make `pulumi.ResourceState` conform to the `pulumi.Resource` interface
3. Wait for inputs to resolve inside RPC goroutines rather than doing so
before starting the goroutines
Note that (2) involves a breaking change to `pulumi.ResourceState` that
will require adjusting `tfgen`'s code generation.

It's apparently broken in our CI. Also upgrade pylint to 2.1, which is
apparently the "actual" most recently release according to PyPI.
