Adds Python support for resource transformations aligned with the existing NodeJS support in #3174.
This PR also moves processing of transformations to earlier in the resource construction process (for both NodeJS and Python) to ensure that invariants established in the constructor cannot be violated by transformations. This change can technically be a breaking change, but given that (a) the transformations features was just released in 1.3.0 and (b) the cases where this is a breaking change are uncommon and unlikely to have been reliable anyway - it feels like a change we should make now.
Fixes#3283.
Adds the ability to provide `transformations` to modify the properties and resource options that will be used for any child resource of a component or stack.
This offers an "escape hatch" to modify the behaviour of a component by peeking behind it's abstraction. For example, it can be used to add a resource option (`additionalSecretOutputs`, `aliases`, `protect`, etc.) to a specific known child of a component, or to modify some input property to a child resource if the component does not (yet) expose the ability to control that input directly. It could also be used for more interesting scenarios - such as:
1. Automatically applying tags to all resources that support them in a stack (or component)
2. Injecting real dependencies between stringly-referenced resources in a Helm Chart
3. Injecting explicit names using a preferred naming convention across all resources in a stack
4. Injecting `import` onto all resources by doing a lookup into a name=>id mapping
Because this feature makes it possible to peek behind a component abstraction, it must be used with care in cases where the component is versioned independently of the use of transformations. Also, this can result in "spooky action at a distance", so should be used judiciously. That said - this can be used as an escape hatch to unblock a wide variety of common use cases without waiting on changes to be made in a component implementation.
Each transformation is passed the `resource`, `name`, `type`, `props` and `opts` that are passed into the `Resource` constructor for any resource descended from the resource that has the transformation applied. The transformation callback can optionally return alternate versions of the `props` and `opts` to be used in place of the original values provided to the resource constructor.
Fixes#2068.
For new properties added to `Resource`, we need to make sure to handle cases where these are undefined as they may not be available on versions of `Resource` that come from older SDK versions, which could me side-by-side in a single Pulumi program execution.
Fixes#2938
* Plumbing the custom timeouts from the engine to the providers
* Plumbing the CustomTimeouts through to the engine and adding test to show this
* Change the provider proto to include individual timeouts
* Plumbing the CustomTimeouts from the engine through to the Provider RPC interface
* Change how the CustomTimeouts are sent across RPC
These errors were spotted in testing. We can now see that the timeout
information is arriving in the RegisterResourceRequest
```

```
* Changing the design to use strings
* CHANGELOG entry to include the CustomTimeouts work
* Changing custom timeouts to be passed around the engine as converted value
We don't want to pass around strings - the user can provide it but we want
to make the engine aware of the timeout in seconds as a float64
A resource can be imported by setting the `import` property in the
resource options bag when instantiating a resource. In order to
successfully import a resource, its desired configuration (i.e. its
inputs) must not differ from its actual configuration (i.e. its state)
as calculated by the resource's provider.
There are a few interesting state transitions hiding here when importing
a resource:
1. No prior resource exists in the checkpoint file. In this case, the
resource is simply imported.
2. An external resource exists in the checkpoint file. In this case, the
resource is imported and the old external state is discarded.
3. A non-external resource exists in the checkpoint file and its ID is
different from the ID to import. In this case, the new resource is
imported and the old resource is deleted.
4. A non-external resource exists in the checkpoint file, but the ID is
the same as the ID to import. In this case, the import ID is ignored
and the resource is treated as it would be in all cases except for
changes that would replace the resource. In that case, the step
generator issues an error that indicates that the import ID should be
removed: were we to move forward with the replace, the new state of
the stack would fall under case (3), which is almost certainly not
what the user intends.
Fixes#1662.
Running `pulumi query` over state resources will require the ability to
filter resources by type.
This commit begins the process of making this possible simply, using the
TypeScript user-defined type guards feature. This commit changes the
`CustomResource` constructor to record the `t` argument in the
`__pulumiType` field, which acts as a "sentinel" value in the resource
base, which deriving classes need only check to ensure they are of that
type. For example:
aws.s3.Bucket.isInstance(someOb)
would check the `aws.s3.Bucket.__pulumiType` field, and make sure that
the type field lines up.
Adds a new resource option `aliases` which can be used to rename a resource. When making a breaking change to the name or type of a resource or component, the old name can be added to the list of `aliases` for a resource to ensure that existing resources will be migrated to the new name instead of being deleted and replaced with the new named resource.
There are two key places this change is implemented.
The first is the step generator in the engine. When computing whether there is an old version of a registered resource, we now take into account the aliases specified on the registered resource. That is, we first look up the resource by its new URN in the old state, and then by any aliases provided (in order). This can allow the resource to be matched as a (potential) update to an existing resource with a different URN.
The second is the core `Resource` constructor in the JavaScript (and soon Python) SDKs. This change ensures that when a parent resource is aliased, that all children implicitly inherit corresponding aliases. It is similar to how many other resource options are "inherited" implicitly from the parent.
Four specific scenarios are explicitly tested as part of this PR:
1. Renaming a resource
2. Adopting a resource into a component (as the owner of both component and consumption codebases)
3. Renaming a component instance (as the owner of the consumption codebase without changes to the component)
4. Changing the type of a component (as the owner of the component codebase without changes to the consumption codebase)
4. Combining (1) and (3) to make both changes to a resource at the same time

Fixes#2277.
Adds a new ignoreChanges resource option that allows specifying a list of property names whose values will be ignored during updates. The property values will be used for Create, but will be ignored for purposes of updates, and as a result also cannot trigger replacements.
This is a feature of the Pulumi engine, not of the resource providers, so no new logic is needed in providers to support this feature. Instead, the engine simply replaces the values of input properties in the goal state with old inputs for properties marked as ignoreChanges.
Currently, only top level properties may be specified in ignoreChanges. In the future, this could be extended to support paths to nested properties (including into array elements) with a JSONPath/JMESPath syntax.
This update includes several changes to core `@pulumi/pulumi` constructs that will not play nicely
in side-by-side applications that pull in prior versions of this package. As such, we are rev'ing
the minor version of the package from 0.16 to 0.17. Recent version of `pulumi` will now detect,
and warn, if different versions of `@pulumi/pulumi` are loaded into the same application. If you
encounter this warning, it is recommended you move to versions of the `@pulumi/...` packages that
are compatible. i.e. keep everything on 0.16.x until you are ready to move everything to 0.17.x.
### Improvements
- `Output<T>` now 'lifts' property members from the value it wraps, simplifying common coding patterns. Note: this wrapping only happens for POJO values, not `Output<Resource>`s.
- Depending on a **Component** Resource will now depend on all other Resources parented by that
Resource. This will help out the programming model for Component Resources as your consumers can
just depend on a Component and have that automatically depend on all the child Resources created
by that Component. Note: this does not apply to a **Custom** resource. Depending on a
CustomResource will still only wait on that single resource being created, not any other Resources
that consider that CustomResource to be a parent.
These changes add a new flag to the various `ResourceOptions` types that
indicates that a resource should be deleted before it is replaced, even
if the provider does not require this behavior. The usual
delete-before-replace cascade semantics apply.
Fixes#1620.
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.
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.
Rather than placing these combinators directly on the Output class,
which feels odd because they are special purpose to iterables, and deal
with not only Outputs but also Inputs, we will place them on a
separate and dedicated iterable module for these utility helpers.
This change adds some new constructors for output properties:
1) We alias `Output.create` to `output`, more like Promise's various
construction methods. This reads better and is more discoverable.
2) A new `Output.createMap` function will accept an array of inputs,
along with a selector function for key/value pairs, and produces
an output map with said keys and values inside of it.
3) A new `Output.createGroupByMap` functon will similarly accept an
array of inputs and a key/value selector, however it creates an
output map with said keys, but where values are arrays of values,
and all duplicate keys will lead to appending to said arrays.
Tests to come in a subsequent checkin.
Suppose you have `pulumi.output(o).apply(foo)`, with `o` being type `O`
and `foo` taking type `O` as an argument. If `O` is a type with methods,
this will fail to type check.
The reason is that `UnwrappedObject<T>` (as well as the other
`Unwrapped*` types) will recursively wrap the types of field values
whose type was `Function`. Since `UnwrappedObject<Function>` is not the
same as `Function`, we fail to type check. Note that this does not
result in an actual "boxed" object -- this is purely at the type level.
This commit resolves this by considering `Function` a primitive type,
which will cause us to not wrap the types of field values, instead
leaving them as `Function`.
