These changes fix a bug in the Python runtime that would cause any
awaitable input properties passed to a resource that are missing
from the resource's output properties to be awaited twice. The fix is
straightforward: rather than roundtripping an input property through
serialize/deserialize, just deserialized the already-serialized input
property.
Fixes#2940.
Adds support for additional cloud secrets providers (AWS KMS, Azure KeyVault, Google Cloud KMS, and HashiCorp Vault) as the encryption backend for Pulumi secrets. This augments the previous choice between using the app.pulumi.com-managed secrets encryption or a fully-client-side local passphrase encryption.
This is implemented using the Go Cloud Development Kit support for pluggable secrets providers.
Like our cloud storage backend support which also uses Go Cloud Development Kit, this PR also bleeds through to users the URI scheme's that the Go CDK defines for specifying each of secrets providers - like `awskms://alias/LukeTesting?region=us-west-2` or `azurekeyvault://mykeyvaultname.vault.azure.net/keys/mykeyname`.
Also like our cloud storage backend support, this PR doesn't solve for how to configure the cloud provider client used to resolve the URIs above - the standard ambient credentials are used in both cases. Eventually, we will likely need to provide ways for both of these features to be configured independently of each other and of the providers used for resource provisioning.
These changes make the `pulumi.runtime.invoke` function invokable in a
synchronous manner. Because this function still needs to perform
asynchronous work under the covers--namely awaiting a provider URN and
ID if a provider instance is present in the `InvokeOptions`--this
requires some creativity. This creativity comes in the form of a helper
function, `_sync_await`, that performs a logical yield from the
currently running event, manually runs the event loop until the given
future completes, performs a logical resume back to the
currently executing event, and returns the result of the future.
The code in `_sync_await` is a bit scary, as it relies upon knowledge of
(and functions in) the internals of the `asyncio` package. The necessary
work performed in this function was derived from the implementations of
`task_step` (which pointed out the need to call `_{enter,leave}_task`)
and `BaseEventLoop.run_forever` (which illustrated how the event loop is
pumped). In addition to potential breaking changes to these internals,
the code may not work if a user has provided an alternative implementation
for `EventLoop`. That said, the code is a close enough copy of
`BaseEventLoop.run_forever` that it should be a reasonable solution.
Provides an additional helper function to read outputs from a stack reference in case it is known that the stack output must be present. This is similar to the design for config.get and config.require.
Fixes#2343.
A workaround for #2695
During the plugin installation, we create a temporary folder, unzip the binary, and then rename the folder to a permanent name. The rename fails 90% of the time with access denied. An immediate retry of renaming seems to always succeed.
These changes add support for passing `ignoreChanges` paths to resource
providers. This is intended to accommodate providers that perform diffs
between resource inputs and resource state (e.g. all Terraform-based
providers, the k8s provider when using API server dry-runs). These paths
are specified using the same syntax as the paths used in detailed diffs.
In addition to passing these paths to providers, the existing support
for `ignoreChanges` in inputs has been extended to accept paths rather
than top-level keys. It is an error to specify a path that is missing
one or more component in the old or new inputs.
Fixes#2936, #2663.
https://www.pulumi.com/docs/reference/changelog/ contains changelog entries for older versions, but hasn't been kept up-to-date. We'll be removing those from that page, after having moved the older entries to the CHANGELOG.md in this repo, which this commit does.
If we encounter a provider with old inputs but no old outputs when reading
a checkpoint file, use the old inputs as the old outputs. This handles the
scenario where the CLI is being upgraded from a version that did not
reflect provider inputs to provider outputs, and a provider is being
upgraded from a version that did not implement `DiffConfig` to a version
that does.

Dynamic providers in Python.
This PR uses [dill](https://pypi.org/project/dill/) for code serialization, along with a customization to help ensure deterministic serialization results.
One notable limitation - which I believe is a general requirement of Python - is that any serialization of Python functions must serialize byte code, and byte code is not safely versioned across Python versions. So any resource created with Python `3.x.y` can only be updated by exactly the same version of Python. This is very constraining, but it's not clear there is any other option within the realm of what "dynamic providers" are as a feature. It is plausible that we could ensure that updates which only update the serialized provider can avoid calling the dynamic provider operations, so that version updates could still be accomplished. We can explore this separately.
```py
from pulumi import ComponentResource, export, Input, Output
from pulumi.dynamic import Resource, ResourceProvider, CreateResult, UpdateResult
from typing import Optional
from github import Github, GithubObject
auth = "<auth token>"
g = Github(auth)
class GithubLabelArgs(object):
owner: Input[str]
repo: Input[str]
name: Input[str]
color: Input[str]
description: Optional[Input[str]]
def __init__(self, owner, repo, name, color, description=None):
self.owner = owner
self.repo = repo
self.name = name
self.color = color
self.description = description
class GithubLabelProvider(ResourceProvider):
def create(self, props):
l = g.get_user(props["owner"]).get_repo(props["repo"]).create_label(
name=props["name"],
color=props["color"],
description=props.get("description", GithubObject.NotSet))
return CreateResult(l.name, {**props, **l.raw_data})
def update(self, id, _olds, props):
l = g.get_user(props["owner"]).get_repo(props["repo"]).get_label(id)
l.edit(name=props["name"],
color=props["color"],
description=props.get("description", GithubObject.NotSet))
return UpdateResult({**props, **l.raw_data})
def delete(self, id, props):
l = g.get_user(props["owner"]).get_repo(props["repo"]).get_label(id)
l.delete()
class GithubLabel(Resource):
name: Output[str]
color: Output[str]
url: Output[str]
description: Output[str]
def __init__(self, name, args: GithubLabelArgs, opts = None):
full_args = {'url':None, 'description':None, 'name':None, 'color':None, **vars(args)}
super().__init__(GithubLabelProvider(), name, full_args, opts)
label = GithubLabel("foo", GithubLabelArgs("lukehoban", "todo", "mylabel", "d94f0b"))
export("label_color", label.color)
export("label_url", label.url)
```
Fixes https://github.com/pulumi/pulumi/issues/2902.
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
```

IgnoreChanges: nil,
AcceptSecrets: true,
AdditionalSecretOutputs: nil,

CustomTimeouts: &pulumirpc.RegisterResourceRequest_CustomTimeouts{

}
```
* 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.
There current RPC model for Pulumi allows secret values to be deeply
embedded in lists or maps, however at the language level, since we
track secrets via `Output<T>` we need to ensure that during
deserialization, if a list or a map contains a secret, we need to
instead treat it as if the entire list or map was a secret.
We have logic in the language runtimes to do this as part of
serialization. There were a few issues this commit addresses:
- We were not promoting secretness across arrays in either Node or
Python
- For Python, our promotion logic was buggy and caused it to behave in
a manner where if any value was secret, the output values of the
object would be corrupted, because we'd incorrectly treat the
outputs as a secret who's value was a map, instead of a map of
values (some of which may be secret).
This caused very confusing behavior, because it would appear that a
resource creation call just did not set various output properties when
one or more of them ended up containing a secret.
Thse changes make a subtle but critical adjustment to the process the
Pulumi engine uses to determine whether or not a difference exists
between a resource's actual and desired states, and adjusts the way this
difference is calculated and displayed accordingly.
Today, the Pulumi engine get the first chance to decide whether or not
there is a difference between a resource's actual and desired states. It
does this by comparing the current set of inputs for a resource (i.e.
the inputs from the running Pulumi program) with the last set of inputs
used to update the resource. If there is no difference between the old
and new inputs, the engine decides that no change is necessary without
consulting the resource's provider. Only if there are changes does the
engine consult the resource's provider for more information about the
difference. This can be problematic for a number of reasons:
- Not all providers do input-input comparison; some do input-state
comparison
- Not all providers are able to update the last deployed set of inputs
when performing a refresh
- Some providers--either intentionally or due to bugs--may see changes
in resources whose inputs have not changed
All of these situations are confusing at the very least, and the first
is problematic with respect to correctness. Furthermore, the display
code only renders diffs it observes rather than rendering the diffs
observed by the provider, which can obscure the actual changes detected
at runtime.
These changes address both of these issues:
- Rather than comparing the current inputs against the last inputs
before calling a resource provider's Diff function, the engine calls
the Diff function in all cases.
- Providers may now return a list of properties that differ between the
requested and actual state and the way in which they differ. This
information will then be used by the CLI to render the diff
appropriately. A provider may also indicate that a particular diff is
between old and new inputs rather than old state and new inputs.
Fixes#2453.
Our logic to export a resource as a stack output transforms the
resource into a plain old object by eliding internal fields and then
just serializing the resource as a POJO.
The custom serialization logic we used here unwrapped an Output
without care to see if it held a secret. Now, when it does, we
continue to return an Output as the thing to be serialized and that
output is marked as a secret.
Fixes#2862
