The scope chain currently does not include module-scope
vairables, which are instead stored on a module object. For
now, we are capturing this module object along with the
scope chain as part of a Lambda object so that we can use
it when evaluating variable references within a lambda
expression.
Fixes#175.
Introduces a free variable AST visitor, and uses this to limit
the environment exposed by the `serizlizeClosure` intrinsic
to only those variables that are referenced by the lambda body.
Fixes#177.
This change slightly refactors the way resources are created and
implemented. We now have two implementations of the Resource interface:
* `resource` (in resource_value.go), which is a snapshot of a resource's
state. All values are resolved and there is no live reference to any
heap state or objects. This will be used when serializing and/or
deserializing snapshots of deployments.
* `objectResource` (in resource_object.go), which is an implementation
of the Resource interface that wraps an underlying, live runtime object.
This currently introduces no functional difference, as fetching Inputs()
amounts to taking a snapshot of the full state. But this at least
gives us a leg to stand on in making sure that output properties are
read at the right times during evaluation.
This is a fundamental part of pulumi/lumi#90.
This change begins to track objects that are implicated in the
creation of computed values. This ultimately translates into the
resource URNs which are used during dependency analysis and
serialization. This is part of pulumi/lumi#90.
In the places we run `go build`, we should use
`go build -i` to save the `.a` files generated
during the build. This ensures the artifacts
are availble for other Go tools (linters, IDEs), and
should also improve build speeds.
The previous checkin exposed some validation
errors that had previously been surpressed,
including an error validating the Permission
statementId's generated by aws.serverless.API.
Adds Check implementation for aws.lambda.Permission
resources using AWS-defined regexps.
Fixes bug in lumidl Check wrapper which was dropping
reported check failures (an regen all rpc files).
Add calls to Get into the AWS provider test framework.
Adds a Permission resource to enable lambda Functions
to be invoked by event sources.
Per #223, we are continuing to discuss whether these
should really be a seperate resource or just an inline
component of a Function resource. However, until we
support cycle-breaking, we'll need them to be a separate
resource type.
Progress on #222.
This change fixes the serialization of resource properties during
deployment checkpoints. We erroneously serialized empty arrays and
empty maps as though they were nil; instead, we want to keep them
serialized as non-nil empty collections, since the presence of a
value might be semantically meaningful. (We still skip nils.)
Also added some test cases.
This change implements `mapper.Encode` "for real" (that is, in a way
that isn't a complete embarrassment). It uses the obvious reflection
trickery to encode a tagged struct and its values as a JSON-like
in-memory map and collection of keyed values.
During this, I took the opportunity to also clean up a few other things
that had been bugging me. Namely, the presence of `mapper.Object` was
always error prone, since it isn't a true "typedef" in the sence that
it carries extra RTTI. Instead of doing that, let's just use the real
`map[string]interface{}` "JSON-map-like" object type. Even better, we
no longer require resource providers to deal with the mapper
infrastructure. Instead, the `Check` function can simply return an
array of errors. It's still best practice to return field-specific errors
to facilitate better diagnostics, but it's no longer required; and I've
added `resource.NewFieldError` to eliminate the need to import mapper.
As of this change, we can also consistently emit RPC structs with `lumi`
tags, rather than `lumi` tags on the way in and `json` on the way out.
This completes pulumi/lumi#183.
The raw AWS API and CloudFormation projection allow
a stage to be created as part of creating a deployment.
This leads to difficulties tracking the ownership of this
extra stage, since it is neither created and owned
seperately, nor is it discoverable after the fact from the
deployment.
We can keep the API simpler by not projecting this feature
of the AWS API into the Lumi resource. The stage will have
to be created seperately in Lumi, and it's lifecycle is well
understood as a separate Lumi resource.
Fixes#202.
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.
Adds support for AWS API Gateway RestApi, Deployment and Stage resources. Together, these enable publishing an HTTP endpoint from a Lumi script.
Also creates the aws.serverless sub-package for higher level serverless abstractions similar to the AWS Serverless Application Model (SAM). Currently includes higher-level Function and API abstractions.
This reverts commit 048c35d428.
I have a pending change that fixes this along with a number of
other issues (including pulumi/lumi#198 and pulumi/lumi#187),
however, it's going to take a little longer and I want to unblock.
This fixespulumi/lumi#200.
The @lumi.out decorator ended up not being required after all.
The engine essentially treats all resource properties as potentially
output properties now, given the way we read back the state from
the provider after essential operations.
This is a good thing, because the evaluator currently doesn't
perform dynamic decoration in a way that would be amenable to
a faithful ECMAScript implementation (see pulumi/lumi#128).
This change eliminates the use of nonstandard tools in our build:
* `go test` automatically uses `GOMAXPROCS` for its parallelism
setting. In modern Go, this is now set to the number of processors.
So, there is no need to set it explicitly using `nproc`.
* We can avoid `realpath` in the `lumijs` executable by making it
a Node.js file and using a relative require import of main.
* We can avoid `realpath` in our Makefiles by just using `pwd`.
This change alters diag.Message to not format strings and, instead,
encourages developers to use the Infof, Errorf, and Warningf varargs
functions. It also tests that arguments are never interepreted as
format strings.
* Makeify more; add a "full build" target
This change uses make for more of our tree. Namely, the AWS provider
and LumiJS compilers each now use make to build and/or install them.
Not only does this bring about some consistency to how we build and
test things, but also made it easy to add a full build target:
$ make all
This target will build, test, and install the core Go tools, the LumiJS
compiler, and the AWS provider, in that order.
Each can be made in isolation, however, which ensures that the inner
loop for those is fast and so that, when it comes to finishing
pulumi/lumi#147, we can easily split them out and make from the top.
There are a few things that annoyed me about the way our CLI works with
directories when loading packages. For example, `lumi pack info some/pack/dir/`
never worked correctly. This is unfortunate when scripting commands.
This change fixes the workspace detection logic to handle these cases.
The AWS tests take a while to run and it's easy to forget. Further,
they are going to start taking quite a bit longer very soon.
So, this change introduces a `make full` target, which is what our
CI tests run. But the ordinary `make` skips the long tests for faster
inner loop verification. Over time, I'm sure we'll get far more
sophisticated with the split between inner vs. outer loop testing,
especially for performance, stress, and so on.
Golint by default doesn't return a non-zero exit code when lint errors
are present. To address this, we need to pass -set_exit_status.
But it gets more complicated: because we are suppressing some lint
warnings, we cannot use -set_exit_status in the lint_quiet target.
For that, we use test -z to fail if any output passes the filter.
Eventually when we do pulumi/lumi#191, we can remove this hack.
If you try to specify egress rules on an EC2-Classic security group,
you get obscure error messages like "The parameter CidrIp is not recognized."
It turns out, the underlying AuthorizeSecurityGroupEgress function
isn't supported on EC2-Classic security groups (those w/out VPCs); see:
https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_AuthorizeSecurityGroupEgress.html
This change adds a check up front for this condition so developers get
a nicer error message.
Changes the Source property on AWS S3 Objects
to be an `in` property.
Adds an AllOptionSettings output property to
store the settings returned from AWS. This
unblocks keeping Beanstalk workign while
we evaluate options for #189.
Silently skip unsupported AWS ElasticBeanstalk
Environment properties in Get operation.
Fixes ARN resource name pair extraction to skip the
"/" between parts of the name pair.
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.
