Functions

func ChunkSize 

func ChunkSize(minPieces uint64) uint64

ChunkSize is a helper method to calculate the size of a chunk depending on the minimum number of pieces required to restore the chunk.

func Fuzz 

func Fuzz() int

Fuzz returns 0, 1 or -1. This can be used to test for random off-by-one errors in the code. For example fuzz can be used to create a File that is either sector aligned or off-by-one.

func Miner 

func Miner(dir string) node.NodeParams

Miner returns an MinerTemplate filled out with the provided dir.

func Retry 

func Retry(tries int, durationBetweenAttempts time.Duration, fn func() error) (err error)

Retry will call 'fn' 'tries' times, waiting 'durationBetweenAttempts' between each attempt, returning 'nil' the first time that 'fn' returns nil. If 'nil' is never returned, then the final error returned by 'fn' is returned.

func TestDir 

func TestDir(dirs ...string) string

TestDir joins the provided directories and prefixes them with the SiaClassic testing directory, removing any files or directories that previously existed at that location.

Types

type DependencyInterruptOnceOnKeyword 

type DependencyInterruptOnceOnKeyword struct {
	modules.ProductionDependencies
	// contains filtered or unexported fields
}

DependencyInterruptOnceOnKeyword is a generic dependency that interrupts the flow of the program if the argument passed to Disrupt equals str and if f was set to true by calling Fail.

func (*DependencyInterruptOnceOnKeyword) Disrupt 

func (d *DependencyInterruptOnceOnKeyword) Disrupt(s string) bool

func (*DependencyInterruptOnceOnKeyword) Fail 

func (d *DependencyInterruptOnceOnKeyword) Fail()

Fail causes the next call to Disrupt to return true if the correct string is provided.
