Functions

func APIRequestID 

func APIRequestID(ctx context.Context) string

func Copy 

func Copy(src interface{}) interface{}

Copy makes a deep copy of an interface.

func CreateAPIRequestID 

func CreateAPIRequestID() string

CreateAPIRequestID creates a random APIRequestId.

func DeriveField 

func DeriveField(pattern string, cVal *string, fs ...*string) (*string, error)

DeriveField deals with the outgoing portion of derived fields. The derived fields' inputs might be in any form - for instance, a derived name field might be set to project/region/name, projects/project/regions/region/objects/name, or just name. This function returns the best reasonable guess at the user's intent. If the current value (cVal) matches any of those, it will return the current value. If it doesn't, it will be ignored (even if nil).

func DeriveFieldArray 

func DeriveFieldArray(pattern string, cVal []string, fs ...interface{}) ([]string, error)

DeriveFieldArray calls DeriveField on each entry in the provided slice. The final entry in the input variadic argument can be a slice, and those values will be replaced by the values in the provided current value.

func DeriveFromPattern 

func DeriveFromPattern(pattern string, cVal *string, fs ...*string) (*string, error)

DeriveFromPattern attempts to achieve the same end goal as DeriveField but by using regular expressions rather than assumptions about the format of the inputs based on the number of `/`. This is important for fields that allow `/` characters in their names.

func Do 

func Do(ctx context.Context, op Operation, retryProvider RetryProvider) error

Do performs op as a retryable operation, using retry to determine when and if to retry. Do will only continue if a OperationNotDone{} is returned. If op() returns another error or no error, Do will finish. OperationNotDone{} may have an error inside of it, indicating that it's a retryable error.

func EmptyValue 

func EmptyValue() (map[string]interface{}, error)

EmptyValue returns an empty value to exclude PARAMETER-type values from being expanded

func ExpandProjectIDsToNumbers added in v1.10.0

func FalseToNil 

func FalseToNil(b *bool) (*bool, error)

FalseToNil returns nil if the pointed-to boolean is 'false' - otherwise returns the pass-in pointer.

IsEmptyValueIndirect returns true if the value provided is "empty", according to the golang rules. This corresponds to whether the value should be sent by the client if the existing value is nil - it is useful for diffing a response against a provided value. The "Indirect" refers to the fact that this method returns correct results even if the provided value is a pointer.

func IsNonRetryableHTTPError 

func IsNonRetryableHTTPError(err error, retryability map[int]Retryability, start time.Time) bool

IsNonRetryableHTTPError returns true if we know that the error is not retryable - in GCP that's a 400, 403, 404, or 409.

MapFromListOfKeyValues turns a [{"key": k, "value": v}, ...] format-map into a normal string-string map. This is useful for a handful of GCP APIs which have chosen to represent maps this way. We expect relatively few of these in newer APIs - it is explicitly against https://aip.dev/apps/2717 - ("such a map is represented by a normal JSON object"). That AIP didn't exist at the time of development of, for instance, Compute v1.

func MatchingSemver 

func MatchingSemver(lp, rp *string) bool

Each key except the last must refer to a map[string]interface{} in m - we will descend into m following those keys. If the maps at the levels above the target are empty after the move, they will be deleted. If there are no maps along the path to `to`, they will be created. If a map above the level of the target is missing, nothing will be done. If the map exists but `target` is not present, `nil` will be inserted at `to`. 

func NameFromSelfLink(sl *string) (*string, error)

NameFromSelfLink takes in a self link string and returns the name. 

func NameToSelfLink(l, r *string) bool

Property contains all information for a field (i.e. property)

func (*Property) IsOptional added in v1.10.3 

func (p *Property) IsOptional() bool

IsOptional returns if the type is an optional type.

func (*Property) TypeEnum added in v1.10.3 

func (p *Property) TypeEnum() FieldType

TypeEnum returns an enum referring to the type.

type PropertyResourceReference added in v1.10.3 

type PropertyResourceReference struct {
	Resource string `yaml:"resource"`
	Field    string `yaml:"field"`
	Format   string `yaml:"format,omitempty"`
	Parent   bool   `yaml:"parent,omitempty"`
}

PropertyResourceReference contains all resource reference information.

type ReqCtxKey 

type ReqCtxKey string

ReqCtxKey is the key type for storing values in the context. Context requires custom type key. 

const (
	DoNotLogRequestsKey ReqCtxKey = "DoNotLogRequestsKey"
	APIRequestIDKey     ReqCtxKey = "APIRequestIDKey"
)

Keys used in context Value.

type Resource 

type Resource interface {
	Describe() ServiceTypeVersion
}

func FetchStateHint 

func FetchStateHint(c []ApplyOption) Resource

FetchStateHint returns either nil or a dcl.Resource representing the pre-apply state.

type Retry 

type Retry interface {
	// RetryAfter returns the amount of time that should elapse before an operation is re-run. Returning
	// Stop indicates that no more retries should occur, and returning zero indicates that the operation
	// should be immediately retried.
	RetryAfter(details *RetryDetails) time.Duration
}

Retry provides an interface for handling retryable operations in a flexible manner.

type RetryDetails 

type RetryDetails struct {
	Request  *http.Request
	Response *http.Response
}

RetryDetails provides information about an operation that a Retry implementation can use to make decisions about when or if to perform further requests.

func SendRequest 

func SendRequest(ctx context.Context, c *Config, verb, url string, body *bytes.Buffer, retryProvider RetryProvider) (*RetryDetails, error)

SendRequest applies the credentials in the provided Config to a request with the specified verb, url, and body. It returns the Response from the server if the request returns a 2XX success code, or the *googleapi.Error if it returns any other code. The retry is optional; if supplied HTTP errors that are deemed temporary will be retried according to the policy implemented by the retry.

type RetryProvider 

type RetryProvider interface {
	// New returns an initialized Retry.
	New() Retry
}

RetryProvider allows callers to provide custom retry behavior.

type Retryability 

type Retryability struct {
	Retryable bool
	Pattern   string

	Timeout time.Duration
	// contains filtered or unexported fields
}

Retryability holds the details for one error code to determine if it is retyable. The regex field is compiled for use in error handling. To be retryable, the boolean must be true and the regex must match.

type Schema added in v1.10.3 

type Schema struct {
	Info       *Info       `yaml:"info"`
	Paths      *Paths      `yaml:"paths"`
	Components *Components `yaml:"components"`
}

Schema is the Entire OpenAPI schema.

func (*Schema) ResolveDefinition added in v1.10.3 

func (s *Schema) ResolveDefinition(ref string) (*Component, error)

ResolveDefinition returns the schema component being referenced.

type ServiceTypeVersion 

type ServiceTypeVersion struct {
	// Service indicates the service to which this resource
	// belongs, e.g., "compute". It is roughly analogous to the
	// K8S "Group" identifier.
	Service string

	// Type identifies the particular type of this resource,
	// e.g., "ComputeInstance". It maps to the K8S "Kind".
	Type string

	// Version is the DCL version of the resource, e.g.,
	// "beta" or "ga".
	Version string
}

ServiceTypeVersion is a tuple that can uniquely identify a DCL resource type.
