  1. Some types are flattened and other approaches are easily lost when flattening occurs. Putting the tag onto the property preserves it even through flattening.
  2. In many ways this behavior is like an augmented `json:omitempty`, so it (IMO) makes sense to have a tag just like for JSON. It makes it clearer when looking at the Go object that the serialization behavior of these fields is special.

func LoadTypes 

func LoadTypes(
	idFactory astmodel.IdentifierFactory,
	config *config.Configuration,
	log logr.Logger,
) *Stage
LoadTypes creates a PipelineStage to load Swagger data.

This information is derived from the Azure Swagger specifications. We parse the Swagger specs and look for any actions that appear to be ARM resources (have PUT methods with types we can use and appropriate names in the action path). Then for each resource, we use the existing JSON AST parser to extract the status type (the type-definition part of swagger is the same as JSON Schema).

func MakeOneOfDiscriminantRequired 

func MakeOneOfDiscriminantRequired() *Stage

MakeOneOfDiscriminantRequired walks the type graph and builds new types for communicating with ARM

func MakeStatusPropertiesOptional 

func MakeStatusPropertiesOptional() *Stage

MakeStatusPropertiesOptional makes all top level Status properties optional. This is required because Status itself is actually optional (it's not set initially) and if any top level properties are not optional they end up always being returned, which makes for an awkward GET response initially (before the Status has been set). It also has implications for updating or patching the CRD resource as patching something in the spec or changing an annotation will deserialize the response from apiserver into the object passed in. If there are any spurious empty properties in Status included they will end up getting overwritten (possibly before the client.Status().Update() call can be made).

func NewStage 

func NewStage(
	id string,
	description string,
	action func(context.Context, *State) (*State, error),
) *Stage

func RemoveEmptyObjects 

func RemoveEmptyObjects(log logr.Logger) *Stage

RemoveEmptyObjects removes Definitions which are empty (an object type with no properties)

func RemoveStatusValidations 

func RemoveStatusValidations() *Stage

RemoveStatusValidations removes property validations from all Status types. This is required because Status is retrieved directly from the ARM API, and there are cases where ARM might return something that isn't actually "valid" according to the validation, but makes sense in context. Some examples:

  1. Status has a modelAsString enum with 2 values, but in a future API version, a 3rd value is added. The fact that the enum is modelAsString allows the service to return the new 3rd value even in old API versions.
  2. Status has an int that must be between 10 and 20. In a future API version, that restriction is relaxed and the same int can now be between 0 and 50.
  3. A bug in the services Swagger specification causes the service to accept enums with any case, but always return the enum all uppercase

In the above cases, if we left validation on the Status types, we would be unable to persist the content returned by the service (apiserver will reject it as not matching the OpenAPI schema). This could be a problem in cases where the resource was created via some other means and then imported into

func RemoveTypeAliases 

func RemoveTypeAliases() *Stage

RemoveTypeAliases creates a pipeline stage removing type aliases

func RenameProperties 

func RenameProperties(cfg *config.ObjectModelConfiguration) *Stage

func RepairSkippingProperties 

func RepairSkippingProperties() *Stage

RepairSkippingProperties repairs any properties that skip one or more versions of an object and are reintroduced. As described in issue #1776, such properties are a problem because they might create incompatibilities between different versions of ASO, or between different versions of a given resource.

To repair these, we need to ensure that objects stored in property bags are always serialized with the same shape. For more details, see https://azure.github.io/azure-service-operator/design/adr-2023-09-skipping-properties/

Repair works by scanning for properties that are dropped between versions of a resource. We keep track of all these properties, and if a specific property appears more than once (implying there are two or more sequence versions of that property) we know a repair is required.

To illustrate, assume we have the following set of objects across versions of our mythical CRM service:

v1: Person(GivenName, FamilyName, Address) v2: Person(KnownAs, FullName, FamilyName) v3: Person(KnownAs, FullName, FamilyName, Address)

Scanning these types, we find:

FamilyName: present in (v1, v2, v3); no issue FullName: present in (v2, v3); no issue KnownAs: also present in (v2, v3); no issue GivenName: present in (v1); no issue

Address: present in (v1, v3); (skipping v2), repair required.

func TransformValidatedFloats 

func TransformValidatedFloats() *Stage

func UnrollRecursiveTypes 

func UnrollRecursiveTypes(log logr.Logger) *Stage

UnrollRecursiveTypes finds types that reference themselves and "unrolls" the reference. So a type that looks like: 

type Error struct {
    code    string
    message string
    errors []Error
}

gets unrolled to look like: 

type Error struct {
    code    string
    message string
    errors []Error_Unrolled
}

where Error_Unrolled looks like: 

type Error_Unrolled struct {
    code    string
    message string
}

The recursive references must be removed because controller-tools doesn't support generating "references" (JSON $ref) so it can't support recursive types today. See https://github.com/kubernetes-sigs/controller-tools/issues/489 for more information. Unrolling these types, while required for controller-tools to function, means THAT THE TYPES WE GENERATE DON'T EXACTLY CONFORM TO THE PUBLISHED API! In practice, we think this is ok for Error types because our observation is that Errors that reference themselves only return a depth of 1 in practice. If we were to unroll all loops (rather than just types that directly reference themselves like we're doing here) that "in practice" observation may no longer hold, so we avoid doing it here (it's also more complicated to do that).

func VerifyNoErroredTypes

func (*Stage) Postrequisites 

func (stage *Stage) Postrequisites() []string

Postrequisites returns the unique ids of stages that must run after this stage

func (*Stage) RequiresPostrequisiteStages 

func (stage *Stage) RequiresPostrequisiteStages(postrequisites ...string)

RequiresPostrequisiteStages declares which stages must be executed after this one has completed Use postrequisites when it is necessary for that later stage to act on the results of this one.

For example, InjectJsonSerializationTests creates round trip serialization tests for any object types that have properties. It's not correct to give InjectJsonSerializationTests a prerequisite on every earlier stage that creates new object types becauses it isn't concerned with where those object came from. However, those earlier stages DO want their new object types to be tested, so they declare a post-requisite on InjectJsonSerializationTests to ensure this happens.

Post-requisites are thus not completely isomorphic with RequiresPrerequisiteStages as there may be supporting stages that are sometimes omitted from execution when targeting different outcomes. Having both pre- and post-requisites allows the dependencies to drop out cleanly when different stages are present.

func (*Stage) RequiresPrerequisiteStages 

func (stage *Stage) RequiresPrerequisiteStages(prerequisites ...string)

RequiresPrerequisiteStages declares which stages must have completed before this one is executed. Use prerequisites to specify stages that must be present for this stage to work - typically this means that the earlier stage is responsible for creating the preconditions required for this stage to operate correctly.
