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.
A recent change to output deserialization resulted in secrets being returned unwrapped. This change addresses the regression, ensuring any unwrapped secret values are rewrapped before being returned.
We recently made a change to the Python codegen to emit `int` type annotations, instead of `float`, for properties that are typed as `schema.IntType`.
But the number values that come back from protobuf structs are always floats (like JSON), so we need to cast the values intended to be integers to `int`.
* 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.
