Two improvements:
1. Don't display "[resource plugin <foo>] installing" if the plugin is already installed.
2. Close the plugin download progress bar before displaying any subsequent output, and only show output of `npm install` when there is an error.
When installing a plugin, previous versions of Pulumi extracted the
plugin tarball to a temp directory and then renamed the temp directory
to the final plugin directory. This was done to prevent concurrent
installs: if a process fails to rename the temp dir because the final
dir already exists, it means another process already installed the
plugin. Unfortunately, on Windows the rename operation often fails due
to aggressive virus scanners opening files in the temp dir.
In order to provide reliable plugin installs on Windows, we now extract
the tarball directly into the final directory, and use file locks to
prevent concurrent installs from toppling over one another.
During install, a lock file is created in the plugin cache directory
with the same name as the plugin's final directory but suffixed with
`.lock`. The process that obtains the lock is responsible for extracting
the tarball. Before it does that, it cleans up any previous temp
directories of failed installs of previous versions of Pulumi. Then it
creates an empty `.partial` file next to the `.lock` file. The
`.partial` file indicates an installation is in-progress. The `.partial`
file is deleted when installation is complete, indicating the plugin was
successfully installed. If a failure occurs during installation, the
`.partial` file will remain indicating the plugin wasn't fully
installed. The next time the plugin is installed, the old installation
directory will be removed and replaced with a fresh install.
This is the same approach Go uses for installing modules in its
module cache.
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.

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.
The logic for validating prompted values in 'new' wasn't quite right,
leading to the possibility of creating Pulumi.yaml files with blank
project names.
This manifests in various ways and I've hit it a number of times
over the past few months because of the way we handle project/stack
name conflicts in 'new' -- which itself is a bit annoying too:
https://github.com/pulumi/pulumi/blob/master/pkg/cmd/pulumi/new.go#L206-L207
Because we substitue a default value of "", and because the prompting
logic assumed default values are always valid, we would skip validation
and therefore accept a blank Pulumi.yaml file.
This generates an invalid project which causes errors elsewhere, such as
error: failed to load Pulumi project located at ".../Pulumi.yaml":
project is missing a 'name' attribute
I hit this all the time with our getting started guide because I've
gone through it so many times and have leftover stacks from prior
run-throughs. I wouldn't be surprised if a lot of people hit this.
The solution here validates all values, including the default.
Note also that we failed to validate the value used by 'new --yes'
which meant you could bypass all validation by passing --yes, leading
to similar outcomes.
I've added a couple new tests for these cases. There is a risk we
depend on illegal default values somewhere which will now be rejected,
but that would seem strange, and assuming the tests pass, I would
assume that's not true. Let me know if that's wrong.
Fixespulumi/pulumi#3255.
* Revise host mode.
The current implementation of host mode uses a `pulumi host` command and
an ad-hoc communication protocol between the engine and client to
connect a language host after the host has begun listening. The most
significant disadvantages of this approach are the communication
protocol (which currently requires the use of stdout), the host-specific
command, and the difficulty of accommodating the typical program-bound
lifetime for an update.
These changes reimplement host mode by adding engine support for
connecting to an existing language runtime service rather than launching
a plugin. This capability is provided via an engine-specific language
runtime, `client`, which accepts the address of the existing languge
runtime service as a runtime option. The CLI exposes this runtime via
the `--client` flag to the `up` and `preview` commands, which similarly
accepts the address of an existing language runtime service as an
argument. These changes also adjust the automation API to consume the
new host mode implementation.
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.

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.
We make several calls to `os/user`, which uses CGO and means
cross-compilation is not possible. This replaces `os/user` with the
`luser` package, which is a drop-in replacement which does not use `CGO`
