Functions

func IsLatest

func IsLatest(version string) bool

Types

type ByTiming

type ByTiming []*Trace

ByTiming implements sort.Interface for []*packageservice.Trace based on the Timing field.

func (ByTiming) Len

func (a ByTiming) Len() int

func (ByTiming) Less

func (a ByTiming) Less(i, j int) bool

func (ByTiming) Swap

func (a ByTiming) Swap(i, j int)

type ManifestCache

type ManifestCache interface {
	ReadManifest(packageArn string, packageVersion string) ([]byte, error)
	WriteManifest(packageArn string, packageVersion string, content []byte) error
}

ManifestCache caches manifests locally

type ManifestCacheMem

type ManifestCacheMem struct {
	// contains filtered or unexported fields
}

ManifestCacheMem stores cache in memory

func ManifestCacheMemNew

func ManifestCacheMemNew() *ManifestCacheMem

func (ManifestCacheMem) CacheKey

func (c ManifestCacheMem) CacheKey(packageArn string, packageVersion string) string

func (ManifestCacheMem) ReadManifest

func (c ManifestCacheMem) ReadManifest(packageArn string, packageVersion string) ([]byte, error)

func (ManifestCacheMem) WriteManifest

func (c ManifestCacheMem) WriteManifest(packageArn string, packageVersion string, content []byte) error

type PackageResult

type PackageResult struct {
	PackageName            string
	Version                string
	PreviousPackageVersion string
	Operation              string
	Timing                 int64
	Exitcode               int64
	Environment            map[string]string
	Trace                  []*Trace
}

PackageResult contains all data collected in one install/upgrade/uninstall and gets reported back to PackageService

type PackageService

type PackageService interface {
	PackageServiceName() string
	DownloadManifest(tracer trace.Tracer, packageName string, version string) (string, string, bool, error)
	DownloadArtifact(tracer trace.Tracer, packageName string, version string) (string, error)
	ReportResult(tracer trace.Tracer, result PackageResult) error
}

PackageService is used to determine the latest version and to obtain the local repository content for a given version.

type Trace

type Trace struct {
	Operation string
	Exitcode  int64
	Timing    int64
}

Trace contains one specific operation done for the agent install/upgrade/uninstall

func ConvertToPackageServiceTrace

func ConvertToPackageServiceTrace(traces []*trace.Trace) []*Trace

ConvertToPackageServiceTrace will return traces compatible with PackageService
