Release note for CHANGELOG:

NONE

Previously:

/Users/bflad/src/github.com/terraform-providers/terraform-provider-aws/aws/resource_aws_appautoscaling_policy.go:333:18: R004: ResourceData.Set() incompatible value type: []*github.com/aws/aws-sdk-go/service/applicationautoscaling.Alarm

The alarms attribute was never actually implemented:

  • d.Set() never would have set anything in the Terraform state due to silently ignoring the error above, so Terraform configuration references to the attribute would always have been invalid trying to reference a non-existent resource attribute
  • Configuring alarms in a configuration was never valid as it would not have done anything (CloudWatch Alarms are a read-only property of Application Auto Scaling Policies)
  • Not acceptance tested
  • Not documented

Due to these conditions and since there are no associated bug reports or feature requests for this attribute, it feels safe to bypass our normal attribute deprecation/removal process and just remove the errant attribute definition from the schema. If desired in the future, this could be implemented as a Computed: true only attribute.

Output from acceptance testing:

--- PASS: TestAccAWSAppautoScalingPolicy_dynamoDb (34.67s)
--- PASS: TestAccAWSAppautoScalingPolicy_multiplePoliciesSameName (40.33s)

The `alarms` attribute was never actually implemented:

- Configuring `alarms` in a configuration was never valid as it would not have done anything (CloudWatch Alarms are a read-only property of Application Auto Scaling Policies)
- Not acceptance tested
- Not documented
