const ( // GvisorCPUUsageKey is the metadata key to store and retrieve CPU time usage // across save restore. GvisorCPUUsageKey = "gvisor_cpu_usage" // GvisorWallTimeKey is the metadata key to store and retrieve wall time // across save restore. GvisorWallTimeKey = "gvisor_wall_time" )

Functions ¶
func NewStatefileReader ¶
func NewStatefileReader(source io.ReadCloser, key []byte) (io.ReadCloser, map[string]string, error)
NewStatefileReader returns the statefile's metadata and a reader for it. The ownership of source is transferred to the returned reader.
Types ¶
type SaveOpts ¶
type SaveOpts struct {
// Destination is the save target.
Destination io.Writer
// PagesMetadata is the file into which MemoryFile metadata is stored if
// PagesMetadata is non-nil. Otherwise this content is stored in Destination.
PagesMetadata io.WriteCloser
// PagesFile is the file in which all MemoryFile pages are stored if
// PagesFile is non-nil. Otherwise this content is stored in Destination.
PagesFile stateio.AsyncWriter
// Key is used to enable state integrity check.
Key []byte
// Metadata is save metadata.
Metadata map[string]string
// AppMFExcludeCommittedZeroPages is the value of
// pgalloc.SaveOpts.ExcludeCommittedZeroPages for the application memory
// file.
AppMFExcludeCommittedZeroPages bool
// Resume indicates if the statefile is used for save-resume.
Resume bool
// Autosave indicates if the statefile is used for autosave.
Autosave bool
// StartTime stores the start time of the sandbox.
StartTime time.Time
// CudaCheckpointPath is the path to the cuda-checkpoint binary.
CudaCheckpointPath string
// CudaCheckpointSequential indicates whether cuda-checkpoint should be run
// sequentially (rather than in parallel).
CudaCheckpointSequential bool
}
SaveOpts contains save-related options.
