* Fix an issue with NodeJS host logging
Related to pulumi/pulumi#1694. This issue prevented the language host
from being aware that an engine (logging endpoint) was available and
thus no log messages were sent to the engine. By default, the language
host wrote them to standard out instead, which resulted in a pretty bad
error experience.
This commit fixes the PR and adds machinery to the NodeJS langhost tests
for testing the engine RPC endpoint. It is now possible to give a "log"
function to tests which will be hooked up to the "log" RPC endpoint
normally provided by the Pulumi engine.
* Remove accidental console.log
If a resource's options bag does not specify `protect` or `provider`,
pull a default value from the resource's parent.
In order to allow a parent resource to specify providers for multiple
resource types, component resources now accept an optional map from
package name to provider instance. When a custom resource needs a
default provider from its parent, it checks its parent provider bag for
an entry under its package. If a component resource does not have a
provider bag, its pulls a default from its parent.
These changes also add a `parent` field to `InvokeOptions` s.t. calls to
invoke can use the same behavior as resource creation w.r.t. providers.
Fixes#1735, #1736.
When this argument is not provided, we'll default to the value of
pulumi.getProject(). This is what you want for application level code
anyway and it matches the CLI behavior where if you don't qualify a
key with a package we use the name of the current project.
Fixes#1581
The pulumi runtime used to lazily load and parse both config and
settings data set by the language host. The initial reason for this
design was that we wanted the runtime to be usable in a normal node
environment, but we have moved away from supporting that.
In addition, while we claimed we loaded these value "lazily", we
actually forced their loading quite eagerly when we started
up. However, when capturing config (or settings, as we now do), we
would capture all the logic about loading these values from the
environment.
Even worse, in the case where you had two copies of @pulumi/pulumi
loaded, it would be possible to capture a config object which was not
initialized and then at runtime the initialization logic would try to
read PULUMI_CONFIG from the process environment and fail.
So we adopt a new model where configuration and settings are parsed as
we load their containing modules. In addition, to support SxS
scinerios, we continue to use `process.env` as a way to control both
configuration and settings. This means that `run.ts` must now ensure
that these values are present in the environment before either the
config or runtime modules have been loaded.
Closure serialization now keeps track of the `require`d packages it sees in the function bodies that are serialized during a call to `serializeFunction`.
Also, replaces `serializeFunctionAsync` with `serializeFunction` which accepts richer parameters and return type, deprecating the former API (but leaving it available for now to avoid a breaking change).
Before the changes in #1414, all output properties were guaranteed to
have values after deserialization. After #1414, any properties with no
value were no longer resolved, which was treated as an error. These
changes resolve all missing proprties to `undefined`. If a property is
missing during an update, its `undefined` value is marked as known.
These changes add support for distinguishing an output property with
an unknown value from an output property with a known value that is
undefined.
In a broad sense, the Pulumi property type system is just JSON with the
addition of unknown values. Notably absent, however, are undefined
values. As it stands, our marshalers between JavaScript and Pulumi
property values treat all undefined JavaScript values as unknown Pulumi
values. Unfortunately, this conflates two very different concepts:
unknown Pulumi values are intended to represent values of output
properties that are unknown at time of preview, _not_ values that are
known but undefined. This results in difficulty reasoning about when
transforms are run on output properties as well as confusing output in
the `diff` view of Pulumi preview (user-specifed undefined values are
rendered as unknown values).
As it turns out, we already have a way to decide whether or not an
Output value is known or not: Output.performApply. These changes rename
this property to `isKnown`, clarify its meaning, and take advantage of
the result to decide whether or not an Output value should marshal as
an unknown Pulumi value.
This also allowed these changes to improve the serialization of
undefined object keys and array elements s.t. we better match JavaScript
to JSON serialization behavior (undefined object keys are omitted;
undefined array elements are marshaled as `null`).

Instead of using a shell script to jump from the language host into
node, just invoke node directly. This makes our start-up path a little
simpler to understand and indirectly fixespulumi/home#156, where we
would fail on Windows if the `-exec` script was in a folder that had
spaces in it (due to a subtle interaction between how go launches cmd
files and how cmd.exe parses arguments).
Rather than filtering out the `id` and `urn` properties when serializing
the inputs to an invoke, pass these properties along. This enables the
use of invoke endpoints that accepts these as inputs (e.g. the endpoint
that backs `aws.ec2.getSubnet`).
This change moves us away from using JavaScript RTTI, by way of
`instanceof`, for built-in Pulumi types. If we use `instanceof`,
then the same logical type loaded from separate copies of the
SDK package -- as will happen in SxS scenarios -- are considered
different. This isn't actually what we want. The solution is
simple: implement our own quasi-RTTI solution, using __pulumi*
properties and manual as* and is* functions. Note that we could
have skipped the as* and is* functions, but I found that they led
to slightly easier to read code.
There is one strange thing in here, which I spoke to
@CyrusNajmabadi about: SerializedOutput<T>, because it implements
Output<T> as an _interface_, did not previously masquerade as an
actual Output<T>. In other words, `instanceof` would have returned
false, and indeed a few important properties (like promise) are
missing. This change preserves that behavior, although I'll admit
that this is slightly odd. I suspect we'll want to revisit this as
part of https://github.com/pulumi/pulumi/issues/1074.
Fixes https://github.com/pulumi/pulumi/issues/1203.

As I began to write code using the ability to perform resource
lookups, especially in the code-generators, I realized the way it
was surfaced as an argument to the Resource base constructor would
lead to overload explosion. Instead of doing that, let's pass it
in the ResourceOptions bag.
Prior to this change, if you ended up with multiple Pulumi SDK
packages loaded side-by-side, we would fail in obscure ways. The
reason for this was that we initialize and store important state
in static variables. In the case that you load the same library
twice, however, you end up with separate copies of said statics,
which means we would be missing engine RPC addresses and so on.
This change adds the ability to recover from this situation by
mirroring the initialized state in process-wide environment
variables. By doing this, we can safely recover simply by reading
them back when we detect that they are missing. I think we can
eventually go even further here, and eliminate the entry point
launcher shim altogether by simply having the engine launch the
Node program with the right environment variables. This would
be a nice simplification to the system (fewer moving pieces).
There is still a risk that the separate copy is incompatible.
Presumably the reason for loading multiple copies is that the
NPM/Yarn version solver couldn't resolve to a shared version.
This may yield obscure failure modes should RPC interfaces change.
Figuring out what to do here is part of pulumi/pulumi#957.
This fixespulumi/pulumi#777 and pulumi/pulumi#1017.
This change wires up the new Read RPC method in such a manner that
Pulumi programs can invoke it. This is technically not required for
refreshing state programmatically (as in pulumi/pulumi#1081), however
it's a feature we had eons ago and have wanted since (see
pulumi/pulumi#83), and will allow us to write code like
let vm = aws.ec2.Instance.get("my-vm", "i-07043cd97bd2c9cfc");
// use any property from here on out ...
The way this works is simply by bridging the Pulumi program via its
existing RPC connection to the engine, much like Invoke and
RegisterResource RPC requests already do, and then invoking the proper
resource provider in order to read the state. Note that some resources
cannot be uniquely identified by their ID alone, and so an extra
resource state bag may be provided with just those properties required.
This came almost for free (okay, not exactly) and will come in handy as
we start gaining experience with reading live state from resources.
Also, rename/cleanup a bunch of serialization code.
Also, generate better environment names in the serialized closure code. Thsi code should be much easier to make sense of as hte names will better track to the original names in the user code.
Also, dedupe simple non-capturing functions. This helps ensure we don't spit out N copies of __awaiter (one per file it is declared in).
We now unify new Config("package") and new Config("package:config"),
printing a warning when the new Config("package:config") form is
used and pointing consumers towards just new Config("package")
I've updated our examples to use the newer syntax, but I've added a
test ot the langhost to ensure both forms work.
Fixes#923
Make many fixes to closure serialization
Primary things that i've done as part of this change:
Added support for cyclic objects.
Properly serialize objects that are shared across different function. previously you would get multiple copies, now you properly reference the same copy.
Remove the usages of 'hashes' for functions. Because we track identity of objects, we no longer need them.
Serialize properties of functions (if they have any).
Handle Objects/Functions with different __proto__s than normal. i.e. classes/constructors. but also anything the user may have done themselves to the object.
Handle generator functions.
Handle functions with 'computed' names.
Handle functions with 'symbol' names.
Handle serializing Promises as Promises.
Removed the dual Closure/AsyncClosure tree. One existed solely so we could have a tree without promises (for use in testing maybe?). Because this all exists in a part of our codebase that is entirely async, it's fine to have promises in the tree, and to await them when serializing the Closure to a string.
Handle serializing class-constructors and methods. Including properly handling 'super' calls.
1. Various idiomatic Go and TypeScript fixes
2. Add an integration test that end-to-end roundtrips dependency
information for a simple Pulumi program
3. Add an additional test assert that tests that dependency information
comes from the language host as expected
This brings back the Node.js language plugin's GetRequiredPlugins
function, reimplemented in Go now that the language host has been
rewritten from JavaScript. Fairly rote translation, along with
some random fixes required to get tests passing again.
This change adds a GetRequiredPlugins RPC method to the language
host, enabling us to query it for its list of plugin requirements.
This is language-specific because it requires looking at the set
of dependencies (e.g., package.json files).
It also adds a call up front during any update/preview operation
to compute the set of plugins and require that they are present.
These plugins are populated in the cache and will be used for all
subsequent plugin-related operations during the engine's activity.
We now cache the language plugins, so that we may load them
eagerly too, which we never did previously due to the fact that
we needed to pass the monitor address at load time. This was a
bit bizarre anyhow, since it's really the Run RPC function that
needs this information. So, to enable caching and eager loading
-- which we need in order to invoke GetRequiredPlugins -- the
"phone home" monitor RPC address is passed at Run time.
In a subsequent change, we will switch to faulting in the plugins
that are missing -- rather than erroring -- in addition to
supporting the `pulumi plugin install` CLI command.
