Functions

func Cause

func Cause(cause error) (retriable bool, err error)

Cause is a souped up errors.Cause which can unwrap some standard library errors too. It returns true if any of the intermediate errors had a Timeout() or Temporary() method which returned true.

func ContextError

func ContextError(ctx context.Context, perr *error) bool

ContextError checks to see if ctx is in error.

If it is in error then it overwrites *perr with the context error if *perr was nil and returns true.

Otherwise it returns false.

func Count

func Count(err error)

Count sets the isCounted variable on the error if it conforms to the CountableError interface

func FatalError

func FatalError(err error) error

FatalError makes an error which indicates it is a fatal error and the sync should stop.

func FsError

func FsError(err error) error

FsError makes an error which can keep a record that it is already counted or not

func IsCounted

func IsCounted(err error) bool

IsCounted returns true if err conforms to the CountableError interface and has already been counted

func IsErrNoSpace

func IsErrNoSpace(cause error) (isNoSpc bool)

IsErrNoSpace checks a possibly wrapped error to see if it contains a ENOSPC error

func IsFatalError

func IsFatalError(err error) (isFatal bool)

IsFatalError returns true if err conforms to the Fatal interface and calling the Fatal method returns true.

func IsNoLowLevelRetryError

func IsNoLowLevelRetryError(err error) (isNoLowLevelRetry bool)

IsNoLowLevelRetryError returns true if err conforms to the NoLowLevelRetry interface and calling the NoLowLevelRetry method returns true.

func IsNoRetryError

func IsNoRetryError(err error) (isNoRetry bool)

IsNoRetryError returns true if err conforms to the NoRetry interface and calling the NoRetry method returns true.

func IsRetryAfterError

func IsRetryAfterError(err error) bool

IsRetryAfterError returns true if err is an ErrorRetryAfter

func IsRetryError

func IsRetryError(err error) (isRetry bool)

IsRetryError returns true if err conforms to the Retry interface and calling the Retry method returns true.

func NoLowLevelRetryError

func NoLowLevelRetryError(err error) error

NoLowLevelRetryError makes an error which indicates the sync shouldn't be low level retried.

func NoRetryError

func NoRetryError(err error) error

NoRetryError makes an error which indicates the sync shouldn't be retried.

func RetryAfterErrorTime

func RetryAfterErrorTime(err error) (retryAfter time.Time)

RetryAfterErrorTime returns the time that the RetryAfter error indicates or a Zero time.Time

func RetryError

func RetryError(err error) error

RetryError makes an error which indicates it would like to be retried

func RetryErrorf

func RetryErrorf(format string, a ...interface{}) error

RetryErrorf makes an error which indicates it would like to be retried

func ShouldRetry

func ShouldRetry(err error) bool

ShouldRetry looks at an error and tries to work out if retrying the operation that caused it would be a good idea. It returns true if the error implements Timeout() or Temporary() or if the error indicates a premature closing of the connection.

func ShouldRetryHTTP

func ShouldRetryHTTP(resp *http.Response, retryErrorCodes []int) bool

ShouldRetryHTTP returns a boolean as to whether this resp deserves. It checks to see if the HTTP response code is in the slice retryErrorCodes.

Types

type CountableError

type CountableError interface {
	error
	Count()
	IsCounted() bool
}

CountableError is an optional interface for error. It stores a boolean which signifies if the error has already been counted or not

type ErrorRetryAfter

type ErrorRetryAfter time.Time

ErrorRetryAfter is an error which expresses a time that should be waited for until trying again

func NewErrorRetryAfter

func NewErrorRetryAfter(d time.Duration) ErrorRetryAfter

NewErrorRetryAfter returns an ErrorRetryAfter with the given duration as an endpoint

func (ErrorRetryAfter) Error

func (e ErrorRetryAfter) Error() string

Error returns the textual version of the error

func (ErrorRetryAfter) RetryAfter

func (e ErrorRetryAfter) RetryAfter() time.Time

RetryAfter returns the time the operation should be retried at or after

type Fataler

type Fataler interface {
	error
	Fatal() bool
}

Fataler is an optional interface for error as to whether the operation should cause the entire operation to finish immediately.

This should be returned from Update or Put methods as required

type NoLowLevelRetrier

type NoLowLevelRetrier interface {
	error
	NoLowLevelRetry() bool
}

NoLowLevelRetrier is an optional interface for error as to whether the operation should not be retried at a low level.

NoLowLevelRetry errors won't be retried by low level retry loops.

type NoRetrier

type NoRetrier interface {
	error
	NoRetry() bool
}

NoRetrier is an optional interface for error as to whether the operation should not be retried at a high level.

If only NoRetry errors are returned in a sync then the sync won't be retried.

This should be returned from Update or Put methods as required

type Retrier

type Retrier interface {
	error
	Retry() bool
}

Retrier is an optional interface for error as to whether the operation should be retried at a high level.

This should be returned from Update or Put methods as required

type RetryAfter

type RetryAfter interface {
	error
	RetryAfter() time.Time
}

RetryAfter is an optional interface for error as to whether the operation should be retried after a given delay

This should be returned from Update or Put methods as required and will cause the entire sync to be retried after a delay.
