Types

type Formic

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

func NewFormic

func NewFormic(fsid string, addr string, concurrency int, ftlsConfig *ftls.Config, opts ...grpc.DialOption) *Formic

func (*Formic) Check

func (f *Formic) Check(ctx context.Context, parentINode uint64, childName string) (response string, err error)

func (*Formic) Close

func (f *Formic) Close()

Close will shutdown outgoing connectivity and stop all background goroutines; note that the Formic is no longer usable after a call to Close, including using Startup.

func (*Formic) Create

func (f *Formic) Create(ctx context.Context, parentINode uint64, childName string, childAttr *pb.Attr) (resultingChildAttr *pb.Attr, err error)

func (*Formic) CreateFS

func (f *Formic) CreateFS(ctx context.Context, token string, name string) (fsid string, err error)

func (*Formic) DeleteFS

func (f *Formic) DeleteFS(ctx context.Context, token string, fsid string) (err error)

func (*Formic) GetAttr

func (f *Formic) GetAttr(ctx context.Context, iNode uint64) (attr *pb.Attr, err error)

func (*Formic) GetXAttr

func (f *Formic) GetXAttr(ctx context.Context, iNode uint64, name string, size uint32, position uint32) (xAttr []byte, err error)

func (*Formic) GrantAddressFS

func (f *Formic) GrantAddressFS(ctx context.Context, token string, fsid string, address string) (err error)

func (*Formic) InitFS

func (f *Formic) InitFS(ctx context.Context) (err error)

func (*Formic) ListFS

func (f *Formic) ListFS(ctx context.Context, token string) (list []*pb.FSIDName, err error)

func (*Formic) ListXAttr

func (f *Formic) ListXAttr(ctx context.Context, iNode uint64, size uint32, position uint32) (xAttr []byte, err error)

func (*Formic) Lookup

func (f *Formic) Lookup(ctx context.Context, parent uint64, name string) (attr *pb.Attr, err error)

func (*Formic) MkDir

func (f *Formic) MkDir(ctx context.Context, parent uint64, name string, attr *pb.Attr) (resultingAttr *pb.Attr, err error)

func (*Formic) Read

func (f *Formic) Read(ctx context.Context, iNode uint64, offset int64, size int64) (payload []byte, err error)

func (*Formic) ReadDirAll

func (f *Formic) ReadDirAll(ctx context.Context, iNode uint64) (readDirAllEnts []*pb.ReadDirAllEnt, err error)
func (f *Formic) ReadLink(ctx context.Context, iNode uint64) (target string, err error)

func (*Formic) Remove

func (f *Formic) Remove(ctx context.Context, parent uint64, name string) (err error)

func (*Formic) RemoveXAttr

func (f *Formic) RemoveXAttr(ctx context.Context, iNode uint64, name string) (err error)

func (*Formic) Rename

func (f *Formic) Rename(ctx context.Context, oldParent uint64, newParent uint64, oldName string, newName string) (err error)

func (*Formic) RevokeAddressFS

func (f *Formic) RevokeAddressFS(ctx context.Context, token string, fsid string, address string) (err error)

func (*Formic) SetAttr

func (f *Formic) SetAttr(ctx context.Context, attr *pb.Attr, valid uint32) (resultingAttr *pb.Attr, err error)

func (*Formic) SetXAttr

func (f *Formic) SetXAttr(ctx context.Context, iNode uint64, name string, value []byte, position uint32, flags uint32) (err error)

func (*Formic) ShowFS

func (f *Formic) ShowFS(ctx context.Context, token string, fsid string) (name string, addresses []string, err error)

func (*Formic) Shutdown

func (f *Formic) Shutdown(ctx context.Context) error

Shutdown will close any existing connections; note that Startup may automatically get called with any further activity, but it will use a new connection. To ensure the Formic has no further activity, use Close.

func (*Formic) Startup

func (f *Formic) Startup(ctx context.Context) error

func (*Formic) StatFS

func (f *Formic) StatFS(ctx context.Context) (blocks uint64, bFree uint64, bAvail uint64, files uint64, fFree uint64, bSize uint32, nameLen uint32, frSize uint32, err error)
func (f *Formic) SymLink(ctx context.Context, parent uint64, name string, target string, uid uint32, gid uint32) (attr *pb.Attr, err error)

func (*Formic) UpdateFS

func (f *Formic) UpdateFS(ctx context.Context, token string, fsid string, newName string) (err error)

func (*Formic) Write

func (f *Formic) Write(ctx context.Context, iNode uint64, offset int64, payload []byte) (err error)

type FuseFormic

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

FuseFormic is a client that glues a mountpoint to a Formic server via the Fuse kernel interface.

func NewFuseFormic

func NewFuseFormic(cfg *FuseFormicConfig) *FuseFormic

func (*FuseFormic) Serve

func (f *FuseFormic) Serve() error

Serve will run forever, or until an error occurs, continuously handling Fuse requests and Formic responses.

type FuseFormicConfig

type FuseFormicConfig struct {
	Logger     *zap.Logger
	Mountpoint string
	Address    string
	FSID       string
	AllowOther bool
	ReadOnly   bool
}
