var AppFs = afero.NewOsFs()

wrapper over filesystem, useful for mocking in tests

Functions ¶

func NewBoltConn ¶

func NewBoltConn() (*bolt.DB, error)

func StartGRPCServer ¶

func StartGRPCServer() (*grpc.Server, error)

Types ¶

type Bundle ¶

type Bundle struct {
	ContainerId string
	Bundle      string
}

The bundle includes path to bundle and the runc/podman container id of the bundle. The bundle is a folder that includes the oci spec config.json as well as the rootfs used for setting up the container. Sometimes rootfs can be defined elsewhere. Podman adds extra directories and files in their bundle including a file called attach which is a unix socket for attaching stdin, stdout to the terminal

type Client ¶

type Client struct {
	CRIU *utils.Criu
	// contains filtered or unexported fields
}

func InstantiateClient ¶

func InstantiateClient() (*Client, error)

func (*Client) ContainerDump ¶

func (c *Client) ContainerDump(dir string, containerId string) error

func (*Client) ContainerRestore ¶

func (c *Client) ContainerRestore(imgPath string, containerId string) error

func (*Client) Dump ¶

func (c *Client) Dump(dir string, pid int32) error

func (*Client) Restore ¶

func (c *Client) Restore(args *task.RestoreArgs) (*int32, error)

func (*Client) RuncDump ¶

func (c *Client) RuncDump(root, containerId string, opts *container.CriuOpts) error

func (*Client) RuncRestore ¶

func (c *Client) RuncRestore(imgPath, containerId string, opts *container.RuncOpts) error

func (*Client) WriteOnlyFds ¶

func (c *Client) WriteOnlyFds(openFds []*task.OpenFilesStat, pid int32) []string

WriteOnlyFds takes a snapshot of files that are open (in writeonly) by process PID and outputs full paths. For concurrent processes (multithreaded) this can be dangerous and lead to weird race conditions (maybe). To avoid actually using ptrace (TODO NR) we loop through the openFds of the process and check the flags.

type ClientLogs ¶

type ClientLogs struct {
	Timestamp string `json:"timestamp"`
	Source    string `json:"source"`
	Level     string `json:"level"`
	Msg       string `json:"msg"`
}

type DB ¶

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

func NewDB ¶

func NewDB() *DB

func (*DB) CreateOrUpdateCedanaProcess ¶

func (db *DB) CreateOrUpdateCedanaProcess(id string, state *task.ProcessState) error

KISS for now - but we may want to separate out into subbuckets as we add more checkpointing functionality (like incremental checkpointing or GPU checkpointing) structure is default -> xid, xid -> pid: state (arrows denote buckets)

func (*DB) GetLatestLocalCheckpoints ¶

func (db *DB) GetLatestLocalCheckpoints(id string) ([]*string, error)

func (*DB) GetPID ¶

func (db *DB) GetPID(id string) (int32, error)

func (*DB) GetStateFromID ¶

func (db *DB) GetStateFromID(id string) (*task.ProcessState, error)

This automatically gets the latest entry in the job bucket

func (*DB) GetStateFromPID ¶

func (db *DB) GetStateFromPID(pid int32) (*task.ProcessState, error)

func (*DB) UpdateProcessStateWithID ¶

func (db *DB) UpdateProcessStateWithID(id string, state *task.ProcessState) error

func (*DB) UpdateProcessStateWithPID ¶

func (db *DB) UpdateProcessStateWithPID(pid int32, state *task.ProcessState) error

type GrpcService ¶

type GrpcService interface {
	Register(*grpc.Server) error
}

Unused for now...

type Server ¶

type Server struct {
	Lis net.Listener
	// contains filtered or unexported fields
}

func (*Server) New ¶

func (s *Server) New() (*grpc.Server, error)

type UploadResponse ¶

type UploadResponse struct {
	UploadID  string `json:"upload_id"`
	PartSize  int    `json:"part_size"`
	PartCount int    `json:"part_count"`
}
