This assert is not correct in the case of pointer input types, in
particular `pulumi.stringPtr`. Though these types are not assignable,
they are convertible.
The redesign is focused around providing better static typings and
improved ease-of-use for the Go SDK. Most of the redesign revolves
around three pivots:
- Strongly-typed inputs, especially for nested types
- Struct-based resource and invoke APIs
- Ease-of-use of Apply
1. Strongly-typed inputs
Input is the type of a generic input value for a Pulumi resource.
This type is used in conjunction with Output to provide polymorphism
over strongly-typed input values.
The intended pattern for nested Pulumi value types is to define an
input interface and a plain, input, and output variant of the value
type that implement the input interface.
For example, given a nested Pulumi value type with the following shape:
```
type Nested struct {
Foo int
Bar string
}
```
We would define the following:
```
var nestedType = reflect.TypeOf((*Nested)(nil)).Elem()
type NestedInput interface {
pulumi.Input
ToNestedOutput() NestedOutput
ToNestedOutputWithContext(context.Context) NestedOutput
}
type Nested struct {
Foo int `pulumi:"foo"`
Bar string `pulumi:"bar"`
}
type NestedInputValue struct {
Foo pulumi.IntInput `pulumi:"foo"`
Bar pulumi.StringInput `pulumi:"bar"`
}
func (NestedInputValue) ElementType() reflect.Type {
return nestedType
}
func (v NestedInputValue) ToNestedOutput() NestedOutput {
return pulumi.ToOutput(v).(NestedOutput)
}
func (v NestedInputValue) ToNestedOutputWithContext(ctx context.Context) NestedOutput {
return pulumi.ToOutputWithContext(ctx, v).(NestedOutput)
}
type NestedOutput struct { *pulumi.OutputState }
func (NestedOutput) ElementType() reflect.Type {
return nestedType
}
func (o NestedOutput) ToNestedOutput() NestedOutput {
return o
}
func (o NestedOutput) ToNestedOutputWithContext(ctx context.Context) NestedOutput {
return o
}
func (o NestedOutput) Foo() pulumi.IntOutput {
return o.Apply(func (v Nested) int {
return v.Foo
}).(pulumi.IntOutput)
}
func (o NestedOutput) Bar() pulumi.StringOutput {
return o.Apply(func (v Nested) string {
return v.Bar
}).(pulumi.StringOutput)
}
```
The SDK provides input and output types for primitives, arrays, and
maps.
2. Struct-based APIs
Instead of providing expected output properties in the input map passed
to {Read,Register}Resource and returning the outputs as a map, the user
now passes a pointer to a struct that implements one of the Resource
interfaces and has appropriately typed and tagged fields that represent
its output properties.
For example, given a custom resource with an int-typed output "foo" and
a string-typed output "bar", we would define the following
CustomResource type:
```
type MyResource struct {
pulumi.CustomResourceState
Foo pulumi.IntOutput `pulumi:"foo"`
Bar pulumi.StringOutput `pulumi:"bar"`
}
```
And invoke RegisterResource like so:
```
var resource MyResource
err := ctx.RegisterResource(tok, name, props, &resource, opts...)
```
Invoke arguments and results are also provided via structs, but use
plain-old Go types for their fields:
```
type MyInvokeArgs struct {
Foo int `pulumi:"foo"`
}
type MyInvokeResult struct {
Bar string `pulumi:"bar"`
}
var result MyInvokeResult
err := ctx.Invoke(tok, MyInvokeArgs{Foo: 42}, &result, opts...)
```
3. Ease-of-use of Apply
All `Apply` methods now accept an interface{} as the callback type.
The provided callback value must have one of the following signatures:
func (v T) U
func (v T) (U, error)
func (ctx context.Context, v T) U
func (ctx context.Context, v T) (U, error)
T must be assignable from the ElementType of the Output. If U is a type
that has a registered Output type, the result of the Apply will be the
corresponding Output type. Otherwise, the result of the Apply will be
AnyOutput.

A regression was introduced when we added support for non-Node.js Pulumi programs to run Policy Packs. With that change, we now pass the Policy Pack's full path as the plugin's pwd (so that it would load the `@pulumi/pulumi/cmd/run-policy-pack` Node module from the Policy Pack's node_modules rather than the program's node_modules), but we also pass the path to the policy pack as well. If the path is a full rooted path, this would work fine, and that's what our tests do. However, if a relative path is specified, then it will be looking to load the Policy Pack relative to the pwd, which doesn't produce a correct path leading to failures trying to load the Policy Pack.
Since the pwd is the policy pack path, we can simply pass the path as `"."` to the analyzer plugin, and it will load the policy pack in its pwd.
This change adds support for setting `PULUMI_PREFER_YARN` to true to opt-in to preferring `yarn` over `npm` when installing Node.js dependencies (and publishing Policy Packs). If `PULUMI_PREFER_YARN` is truthy, but `yarn` cannot be found on `$PATH`, we fallback to using `npm`. If `npm` can't be found on `$PATH`, we provide a more helpful error message.
Codepaths which could result in a hang will print a message to the console indicating the problem, along with a link to documentation on how to restructure code to best address it.
`StackReference.getOutputSync` and `requireOutputSync` have been deprecated as they may cause hangs on some combinations of Node and certain OS platforms. `StackReference.getOutput` and `requireOutput` should be used instead.

Before, we got a panic. in the createStack, when we had a non-default
secrets provider, we were assuming the name of the stack was correct
if we were in non-interactive mode
This commit adds a guard against this by doing a final validation of
the stack name *before* we even get into the createStack func
This means, that we get the following (and not the panic)
```
▶ pulumi stack init -s "org/" --secrets-provider="gcpkms://"
error: A stack name may only contain alphanumeric, hyphens, underscores, and periods
```
- If an untargeted create would not affect the inputs of any targeted
resources, do not fail the update. Untargeted creates that are
directly dependend on by targeted resources will still cause failures
that inform the user to add the untargeted resources to the --target
list.
- Users may now pass the `--target-dependents` flag to allow targeted
destroys to automatically target dependents that must be destroyed in
order to destroy an explicitly targeted resource.
- Use a mutex + condition variable instead of a channel for
synchronizaiton in order to allow multiple calls to resolve/reject
- Properly handle outputs that are resolved to other outputs, especially
if those outputs are not of exactly type Output
- Remove the Value() methods that allowed prompt access to output values
- Add variants of `Apply` that take a context parameter
- Ensure that resource outputs properly incorporate their resource as
a dependency
- Make `Output` a plain struct. Uninitialized outputs will be treated as
resolved and unknown. This makes conversions between output
types more ergonomic.
Contributes to #3492.
These changes restore a more-correct version of the behavior that was
disabled with #3014. The original implementation of this behavior was
done in the SDKs, which do not have access to the complete inputs for a
resource (in particular, default values filled in by the provider during
`Check` are not exposed to the SDK). This lack of information meant that
the resolved output values could disagree with the typings present in
a provider SDK. Exacerbating this problem was the fact that unknown
values were dropped entirely, causing `undefined` values to appear in
unexpected places.
By doing this in the engine and allowing unknown values to be
represented in a first-class manner in the SDK, we can attack both of
these issues.
Although this behavior is not _strictly_ consistent with respect to the
resource model--in an update, a resource's output properties will come
from its provider and may differ from its input properties--this
behavior was present in the product for a fairly long time without
significant issues. In the future, we may be able to improve the
accuracy of resource outputs during a preview by allowing the provider
to dry-run CRUD operations and return partially-known values where
possible.
These changes also introduce new APIs in the Node and Python SDKs
that work with unknown values in a first-class fashion:
- A new parameter to the `apply` function that indicates that the
callback should be run even if the result of the apply contains
unknown values
- `containsUnknowns` and `isUnknown`, which return true if a value
either contains nested unknown values or is exactly an unknown value
- The `Unknown` type, which represents unknown values
The primary use case for these APIs is to allow nested, properties with
known values to be accessed via the lifted property accessor even when
the containing property is not fully know. A common example of this
pattern is the `metadata.name` property of a Kubernetes `Namespace`
object: while other properties of the `metadata` bag may be unknown,
`name` is often known. These APIs allow `ns.metadata.name` to return a
known value in this case.
In order to avoid exposing downlevel SDKs to unknown values--a change
which could break user code by exposing it to unexpected values--a
language SDK must indicate whether or not it supports first-class
unknown values as part of each `RegisterResourceRequest`.
These changes also allow us to avoid breaking user code with the new
behavior introduced by the prior commit.
Fixes#3190.
