We have to actually return the value we compute instead of just
dropping it on the floor and treating the underlying values as
primitive.
I ran into this during dogfooding, the added test case would
previously panic.
A new `Secret` property value is introduced, and plumbed across the
engine.
- When Unmarshalling properties /from/ RPC calls, we instruct the
marshaller to retain secrets, since we now understand them in the
rest of the engine.
- When Marshalling properties /to/ RPC calls, we use or tracked data
to understand if the other side of the connection can accept
secrets. If they can, we marshall them in a similar manner to assets
where we have a special object with a signiture specific for secrets
and an underlying value (which is the /plaintext/ value). In cases
where the other end of the connection does not understand secrets,
we just drop the metadata and marshal the underlying value as we
normally would.
- Any secrets that are passed across the engine events boundary are
presently passed as just `[secret]`.
- When persisting secret values as part of a deployment, we use a rich
object so that we can track the value is a secret, but right now the
underlying value is not actually encrypted.
Various providers use properties that begin with "__" to represent
internal metadata that should not be presented to the user. These
changes look for such properties and elide them when displaying diffs.
This change restructures a lot more pertaining to deployments, snapshots,
environments, and the like.
The most notable change is that the notion of a deploy.Source is introduced,
which splits the responsibility between the deploy.Plan -- which simply
understands how to compute and carry out deployment plans -- and the idea
of something that can produce new objects on-demand during deployment.
The primary such implementation is evalSource, which encapsulates an
interpreter and takes a package, args, and config map, and proceeds to run
the interpreter in a distinct goroutine. It synchronizes as needed to
poke and prod the interpreter along its path to create new resource objects.
There are two other sources, however. First, a nullSource, which simply
refuses to create new objects. This can be handy when writing isolated
tests but is also used to simulate the "empty" environment as necessary to
do a complete teardown of the target environment. Second, a fixedSource,
which takes a pre-computed array of objects, and hands those, in order, to
the planning engine; this is mostly useful as a testing technique.
Boatloads of code is now changed and updated in the various CLI commands.
This further chugs along towards pulumi/lumi#90. The end is in sight.
This changes the resource model to persist input and output properties
distinctly, so that when we diff changes, we only do so on the programmer-
specified input properties. This eliminates problems when the outputs
differ slightly; e.g., when the provider normalizes inputs, adds its own
values, or fails to produce new values that match the inputs.
This change simultaneously makes progress on pulumi/lumi#90, by beginning
tracking the resource objects implicated in a computed property's value.
I believe this fixes both #189 and #198.
The AssumeRolePolicyDocument property returned by the AWS IAM GetRole API returns
a URL-encoded JSON string, so we need to decode this before JSON unmarshalling.
The Code property returned by AWS Lambda GetFunction provides a pre-signed S3 URL,
which changes on each call, and is of a different format to what is provided by the user.
For now, we'll not store this back into the Function object.
Add additional output properties to AWS Lambda Function that are stable values returned
from GetFunction.
Also corrects a gap where some property delete operations were not being correctly reported.
This change remembers which properties were computed as outputs,
or even just read back as default values, during a deployment. This
information is required in the before/after comparison in order to
perform an intelligent diff that doesn't flag, for example, the absence
of "default" values in the after image as deletions (among other things).
As I was in here, I also cleaned up the way the provider interface
works, dealing with concrete resource types, making it feel a little
richer and less like we're doing in-memory RPC.
* Eliminate some superfluous "\n"s.
* Remove the redundant properties stored on AWS resources.
* Compute array diff lengths properly (+1).
* Display object property changes from null to non-null as
adds; and from non-null to null as deletes.
* Fix a boolean expression from ||s to &&s. (Bone-headed).
