Functions

func ComputePerfStats

func ComputePerfStats(latencies, throughputs []float64) (madmin.NetLatency, madmin.NetThroughput, error)

ComputePerfStats takes arrays of Latency & Throughput to compute Statistics

func IsConnRefusedErr

func IsConnRefusedErr(err error) bool

IsConnRefusedErr - Checks for "connection refused" errors.

func IsConnResetErr

func IsConnResetErr(err error) bool

IsConnResetErr - Checks for "connection reset" errors.

func IsNetworkOrHostDown

func IsNetworkOrHostDown(err error, expectTimeouts bool) bool

IsNetworkOrHostDown - if there was a network error or if the host is down. expectTimeouts indicates that *context* timeouts are expected and does not indicate a downed host. Other timeouts still returns down.

Types

type Host

type Host struct {
	Name      string
	Port      Port
	IsPortSet bool
}

Host - holds network host IP/name and its port.

func ParseHost

func ParseHost(s string) (*Host, error)

ParseHost - parses string into Host

func (Host) Equal

func (host Host) Equal(compHost Host) bool

Equal - checks whether given host is equal or not.

func (Host) IsEmpty

func (host Host) IsEmpty() bool

IsEmpty - returns whether Host is empty or not

func (Host) MarshalJSON

func (host Host) MarshalJSON() ([]byte, error)

MarshalJSON - converts Host into JSON data

func (Host) String

func (host Host) String() string

String - returns string representation of Host.

func (*Host) UnmarshalJSON

func (host *Host) UnmarshalJSON(data []byte) (err error)

UnmarshalJSON - parses data into Host.

type Port

type Port uint16

Port - network port

func GetFreePort

func GetFreePort() (Port, error)

GetFreePort asks the kernel for a free open port that is ready to use.

func ParsePort

func ParsePort(s string) (p Port, err error)

ParsePort - parses string into Port

func (Port) String

func (p Port) String() string

String - returns string representation of port.

type URL

type URL url.URL

URL - improved JSON friendly url.URL.

func ParseHTTPURL

func ParseHTTPURL(s string) (u *URL, err error)

ParseHTTPURL - parses a string into HTTP URL, string is expected to be of form http:// or https://

func ParseURL

func ParseURL(s string) (u *URL, err error)

ParseURL - parses string into URL.

func (URL) Hostname

func (u URL) Hostname() string

Hostname returns u.Host, stripping any valid port number if present

If the result is enclosed in square brackets, as literal IPv6 addresses are, the square brackets are removed from the result.

func (URL) IsEmpty

func (u URL) IsEmpty() bool

IsEmpty - checks URL is empty or not.

func (URL) MarshalJSON

func (u URL) MarshalJSON() ([]byte, error)

MarshalJSON - converts to JSON string data.

func (URL) Port

func (u URL) Port() string

Port returns the port part of u.Host, without the leading colon.

If u.Host doesn't contain a valid numeric port, Port returns an empty string.

func (URL) String

func (u URL) String() string

String - returns string representation of URL.

func (*URL) UnmarshalJSON

func (u *URL) UnmarshalJSON(data []byte) (err error)

UnmarshalJSON - parses given data into URL.
