const SigKey = PropertyKey("4dabf18193072939515e22adb298388d")

SigKey is sometimes used to encode type identity inside of a map. This is required when flattening into ordinary maps, like we do when performing serialization, to ensure recoverability of type identities later on.

Variables

View Source 
var ArchiveExts = map[string]ArchiveFormat{
	".tar":    TarArchive,
	".tgz":    TarGZIPArchive,
	".tar.gz": TarGZIPArchive,
	".zip":    ZIPArchive,
}

ArchiveExts maps from a file extension and its associated archive and/or compression format.

Functions

func HasSig 

func HasSig(obj PropertyMap, match string) bool

HasSig checks to see if the given property map contains the specific signature match.

func IDStrings 

func IDStrings(ids []ID) []string

IDStrings turns an array of resource IDs into an array of strings.

func IsReqError 

func IsReqError(err error) bool

func NewErrors 

func NewErrors(errs []error) error

NewErrors creates a new error list pertaining to a resource. Note that it just turns around and defers to the same mapping infrastructure used for serialization and deserialization, but it presents a nicer interface.

func NewPropertyError 

func NewPropertyError(typ string, property string, err error) error

NewPropertyError creates a new error pertaining to a resource's property. Note that it just turns around and defers to the same mapping infrastructure used for serialization and deserialization, but it presents a nicer interface.

func NewUniqueHex 

func NewUniqueHex(prefix string, randlen, maxlen int) (string, error)

NewUniqueHex generates a new "random" hex string for use by resource providers. It will take the optional prefix and append randlen random characters (defaulting to 8 if not > 0). The result must not exceed maxlen total characterss (if > 0). Note that capping to maxlen necessarily increases the risk of collisions.

Types

type Archive 

type Archive struct {
	Sig    string                 `json:"4dabf18193072939515e22adb298388d" yaml:"4dabf18193072939515e22adb298388d"` // the unique asset signature (see properties.go).
	Hash   string                 `json:"hash,omitempty" yaml:"hash,omitempty"`                                     // the SHA256 hash of the archive contents.
	Assets map[string]interface{} `json:"assets,omitempty" yaml:"assets,omitempty"`                                 // a collection of other assets/archives.
	Path   string                 `json:"path,omitempty" yaml:"path,omitempty"`                                     // a file on the current filesystem.

}

Archive is a serialized archive reference. It is a union: thus, only one of its fields will be non-nil. Several helper routines exist as members in order to easily interact with archives of different kinds. nolint: lll

func DeserializeArchive 

func DeserializeArchive(obj map[string]interface{}) (*Archive, bool, error)

DeserializeArchive checks to see if the map contains an archive, using its signature, and if so deserializes it.

func NewURIArchive 

func NewURIArchive(uri string) (*Archive, error)

func (*Archive) Archive 

func (a *Archive) Archive(format ArchiveFormat, w io.Writer) error

Archive produces a single archive stream in the desired format. It prefers to return the archive with as little copying as is feasible, however if the desired format is different from the source, it will need to translate.

func (*Archive) Bytes 

func (a *Archive) Bytes(format ArchiveFormat) ([]byte, error)

Bytes fetches the archive contents as a byte slices. This is almost certainly the least efficient way to deal with the underlying streaming capabilities offered by assets and archives, but can be used in a pinch to interact with APIs that demand []bytes.

In this case, value equality is determined only by the hash: even if the contents of two archives come from different sources, they are treated as equal if their hashes match. Similarly, if the contents of two archives come from the same source but the archives have different hashes, the archives are not equal.

type ArchiveReader 

type ArchiveReader interface {
	// Next returns the name and contents of the next member of the archive. If there are no more members in the
	// archive, this function returns ("", nil, io.EOF). The blob returned by a call to Next() must be read in full
	// before the next call to Next().
	Next() (string, *Blob, error)

	// Close terminates the stream.
	Close() error
}

ArchiveReader presents the contents of an archive as a stream of named blobs.

	Hash string `json:"hash,omitempty" yaml:"hash,omitempty"`                                     // the SHA256 hash of the asset contents.
	Text string `json:"text,omitempty" yaml:"text,omitempty"`                                     // a textual asset.
	Path string `json:"path,omitempty" yaml:"path,omitempty"`                                     // a file on the current filesystem.
	URI  string `json:"uri,omitempty" yaml:"uri,omitempty"`                                       // a URI (file://, http://, https://, or custom).

func DeserializeAsset 

func DeserializeAsset(obj map[string]interface{}) (*Asset, bool, error)

func MassageIfUserProgramCodeAsset 

func MassageIfUserProgramCodeAsset(asset *Asset, debug bool) *Asset

MassageIfUserProgramCodeAsset takes the text for a function and cleans it up a bit to make the user visible diffs less noisy. Specifically:

  1. it tries to condense things by changling multiple blank lines into a single blank line.
  2. it normalizs the sha hashes we emit so that changes to them don't appear in the diff.
  3. it elides the with-capture headers, as changes there are not generally meaningful.

TODO(https://github.com/pulumi/pulumi/issues/592) this is baking in a lot of knowledge about pulumi serialized functions. We should try to move to an alternative mode that isn't so brittle. Options include:

  1. Have a documented delimeter format that plan.go will look for. Have the function serializer emit those delimeters around code that should be ignored.
  2. Have our resource generation code supply not just the resource, but the "user presentable" resource that cuts out a lot of cruft. We could then just diff that content here.

func (v PropertyValue) OutputValue() Output

OutputValue fetches the underlying output value (panicking if it isn't a output).

func (PropertyValue) String 

func (v PropertyValue) String() string

String implements the fmt.Stringer interface to add slightly more information to the output.

func (PropertyValue) StringValue 

func (v PropertyValue) StringValue() string

StringValue fetches the underlying string value (panicking if it isn't a string).

func (PropertyValue) TypeString 

func (v PropertyValue) TypeString() string

TypeString returns a type representation of the property value's holder type.

type ReqError 

type ReqError struct {
	K PropertyKey
}

func (*ReqError) Error 

func (err *ReqError) Error() string

type State 

type State struct {
	Type         tokens.Type // the resource's type.
	URN          URN         // the resource's object urn, a human-friendly, unique name for the resource.
	Custom       bool        // true if the resource is custom, managed by a plugin.
	Delete       bool        // true if this resource is pending deletion due to a replacement.
	ID           ID          // the resource's unique ID, assigned by the resource provider (or blank if none/uncreated).
	Inputs       PropertyMap // the resource's input properties (as specified by the program).
	Outputs      PropertyMap // the resource's complete output state (as returned by the resource provider).
	Parent       URN         // an optional parent URN that this resource belongs to.
	Protect      bool        // true to "protect" this resource (protected resources cannot be deleted).
	Dependencies []URN       // the resource's dependencies
}

State is a structure containing state associated with a resource. This resource may have been serialized and deserialized, or snapshotted from a live graph of resource objects. The value's state is not, however, associated with any runtime objects in memory that may be actively involved in ongoing computations.

func NewState 

func NewState(t tokens.Type, urn URN, custom bool, del bool, id ID,
	inputs PropertyMap, outputs PropertyMap, parent URN, protect bool, dependencies []URN) *State

NewState creates a new resource value from existing resource state information.

func (*State) All 

func (s *State) All() PropertyMap

All returns all resource state, including the inputs and outputs, overlaid in that order.

type Status 

type Status int

Status is returned when an error has occurred during a resource provider operation. It indicates whether the operation could be rolled back cleanly (OK). If not, it means the resource was left in an indeterminate state. 

const (
	StatusOK Status = iota
	StatusUnknown
)

type URN 

type URN string

URN is a friendly, but unique, URN for a resource, most often auto-assigned by Pulumi. These are used as unique IDs for objects, and help us to perform graph diffing and resolution of resource objects.

In theory, we could support manually assigned URIs in the future. For the time being, however, we have opted to simplify developers' lives by mostly automating the generation of them algorithmically. The one caveat where it isn't truly automatic is that a developer -- or resource provider -- must provide a semi-unique name part.

Each resource URN is of the form: 

urn:pulumi:<Stack>::<Project>::<Qualified$Type$Name>::<Name>

wherein each element is the following: 

<Stack>                 The stack being deployed into
<Project>               The project being evaluated
<Qualified$Type$Name>   The object type's qualified type token (including the parent type)
<Name>                  The human-friendly name identifier assigned by the developer or provider

In the future, we may add elements to the URN; it is more important that it is unique than it is human-typable.

func NewURN 

func NewURN(stack tokens.QName, proj tokens.PackageName, parentType, baseType tokens.Type, name tokens.QName) URN

NewURN creates a unique resource URN for the given resource object.

func (URN) Name 

func (urn URN) Name() tokens.QName

Name returns the resource name part of a URN.

func (URN) Project 

func (urn URN) Project() tokens.PackageName

Project returns the project name part of a URN.

func (URN) QualifiedType 

func (urn URN) QualifiedType() tokens.Type

QualifiedType returns the resource type part of a URN including the parent type

func (URN) Stack 

func (urn URN) Stack() tokens.QName

Stack returns the resource stack part of a URN.

func (URN) Type 

func (urn URN) Type() tokens.Type

Type returns the resource type part of a URN

func (URN) URNName 

func (urn URN) URNName() string

URNName returns the URN name part of a URN (i.e., strips off the prefix).

type ValueDiff 

type ValueDiff struct {
	Old    PropertyValue // the old value.
	New    PropertyValue // the new value.
	Array  *ArrayDiff    // the array's detailed diffs (only for arrays).
	Object *ObjectDiff   // the object's detailed diffs (only for objects).
}

ValueDiff holds the results of diffing two property values.
