Functions

func NewFs 

func NewFs(ctx context.Context, name, root string, m configmap.Mapper) (fs.Fs, error)

NewFs Initialize backend

Types

type Fs 

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

Fs represents a remote object storage server

func (*Fs) CleanUp 

func (f *Fs) CleanUp(ctx context.Context) (err error)

CleanUp removes all pending multipart uploads older than 24 hours

func (*Fs) Command 

func (f *Fs) Command(ctx context.Context, commandName string, args []string,
	opt map[string]string) (result interface{}, err error)

Command the backend to run a named command

The command run is name args may be used to read arguments from opts may be used to read optional arguments from

The result should be capable of being JSON encoded If it is a string or a []string it will be shown to the user otherwise it will be JSON encoded and shown to the user like that

func (*Fs) Copy 

func (f *Fs) Copy(ctx context.Context, src fs.Object, remote string) (fs.Object, error)

Copy src to this remote using server-side copy operations. This is stored with the remote path given It returns the destination Object and a possible error Will only be called if src.Fs().Name() == f.Name() If it isn't possible then return fs.ErrorCantCopy

func (*Fs) Features 

func (f *Fs) Features() *fs.Features

Features returns the optional features of this Fs

func (*Fs) Hashes 

func (f *Fs) Hashes() hash.Set

Hashes returns the supported hash sets.

func (*Fs) List 

func (f *Fs) List(ctx context.Context, dir string) (entries fs.DirEntries, err error)

List the objects and directories in dir into entries. The entries can be returned in any order but should be for a complete directory.

dir should be "" to list the root, and should not have trailing slashes.

This should return ErrDirNotFound if the directory isn't found.

func (*Fs) ListR 

func (f *Fs) ListR(ctx context.Context, dir string, callback fs.ListRCallback) (err error)

ListR lists the objects and directories of the Fs starting from dir recursively into out.

dir should be "" to start from the root, and should not have trailing slashes.

This should return ErrDirNotFound if the directory isn't found.

It should call callback for each tranche of entries read. These need not be returned in any particular order. If callback returns an error then the listing will stop immediately.

Don't implement this unless you have a more efficient way of listing recursively that doing a directory traversal.

Options defines the configuration for this backend

type StateChangeConf 

type StateChangeConf struct {
	Delay          time.Duration    // Wait this time before starting checks
	Pending        []string         // States that are "allowed" and will continue trying
	Refresh        StateRefreshFunc // Refreshes the current state
	Target         []string         // Target state
	Timeout        time.Duration    // The amount of time to wait before timeout
	MinTimeout     time.Duration    // Smallest time to wait before refreshes
	PollInterval   time.Duration    // Override MinTimeout/backoff and only poll this often
	NotFoundChecks int              // Number of times to allow not found (nil result from Refresh)

	// This is to work around inconsistent APIs
	ContinuousTargetOccurrence int // Number of times the Target state has to occur continuously
}

StateChangeConf is the configuration struct used for `WaitForState`.

func (*StateChangeConf) WaitForStateContext 

func (conf *StateChangeConf) WaitForStateContext(ctx context.Context, entityType string) (interface{}, error)

WaitForStateContext watches an object and waits for it to achieve the state specified in the configuration using the specified Refresh() func, waiting the number of seconds specified in the timeout configuration.

If the Refresh function returns an error, exit immediately with that error.

If the Refresh function returns a state other than the Target state or one listed in Pending, return immediately with an error.

If the Timeout is exceeded before reaching the Target state, return an error.

Otherwise, the result is the result of the first call to the Refresh function to reach the target state.

Cancellation from the passed in context will cancel the refresh loop

type StateRefreshFunc 

type StateRefreshFunc func() (result interface{}, state string, err error)

StateRefreshFunc is a function type used for StateChangeConf that is responsible for refreshing the item being watched for a state change.

It returns three results. `result` is any object that will be returned as the final object after waiting for state change. This allows you to return the final updated object, for example an EC2 instance after refreshing it. A nil result represents not found.

`state` is the latest state of that object. And `err` is any error that may have happened while refreshing the state.

type TimeoutError 

type TimeoutError struct {
	LastError     error
	LastState     string
	Timeout       time.Duration
	ExpectedState []string
}

TimeoutError is returned when WaitForState times out

func (*TimeoutError) Error 

func (e *TimeoutError) Error() string

func (*TimeoutError) Unwrap 

func (e *TimeoutError) Unwrap() error

type UnexpectedStateError 

type UnexpectedStateError struct {
	LastError     error
	State         string
	ExpectedState []string
}

UnexpectedStateError is returned when Refresh returns a state that's neither in Target nor Pending

func (*UnexpectedStateError) Error 

func (e *UnexpectedStateError) Error() string

func (*UnexpectedStateError) Unwrap 

func (e *UnexpectedStateError) Unwrap() error
