Functions

func EncodeTasksCfg 

func EncodeTasksCfg(cfg *TasksCfg) ([]byte, error)

EncoderTasksCfg writes the TasksCfg to a byte slice.

func ErrorIsPermanent 

func ErrorIsPermanent(err error) bool

ErrorIsPermanent returns true if the given error cannot be recovered by retrying. In this case, we will never be able to process the TasksCfg, so we might as well cancel the jobs. TODO(borenet): This should probably be split into two different ErrorIsPermanent functions, in the syncer, and specs packages.

func GetCheckoutRoot 

func GetCheckoutRoot() (string, error)

GetCheckoutRoot returns the path of the root of the checkout.

func Python3LinuxAMD64CIPDPackages

func Python3WindowsAMD64CIPDPackages() []*cipd.Package

func WriteTasksCfg 

func WriteTasksCfg(cfg *TasksCfg, repoDir string) error
