#Gocolorize
Gocolorize is a package that allows Go programs to provide ANSI coloring in a stateful manner. Gocolorize is ideal for logging or cli applications.
![colored tests passing](https://raw.github.com/agtorre/gocolorize/master/screenshot/tests.png)
[![wercker status](https://app.wercker.com/status/ee73c1abee9900c475def6ff9a142237/s "wercker status")](https://app.wercker.com/project/bykey/ee73c1abee9900c475def6ff9a142237)
##Features
- Stateful ANSI coloring
- Supports Foreground and background colors
- Supports a nuber of text properties such as bold or underline
- Color multiple arguments
- Color multiple interfaces, including complex types
- Tests with 100% coverage
- Working examples
- Disable ability for portability
##Install Gocolorize
To install:
$ go get github.com/agtorre/gocolorize
##Usage
Ways to initialize a Colorize object:
```go
//It can be done like this
var c gocolorize.Colorize
c.SetFg(gocolorize.Red)
c.SetBg(gocolorize.Black)
//Or this
c := gocolorize.Colorize{Fg: gocolorize.Red, Bg: gocolorize.Black}
//Or this
c := gocolorize.NewColor("red:black")
```
Once you have an object:
```go
//Call Paint to take inputs and return a colored string
c.Paint("This", "accepts", "multiple", "arguments", "and", "types:", 1, 1.25, "etc")
//If you want a short-hand closure
p = c.Paint
p("Neat")
//To print it:
Fmt.Println(p("test"))
//It can also be appended to other strings, used in logging to stdout, etc.
a := "test " + p("case")
//The closure allows you to reuse the original object, for example
p = c.Paint
c.SetFg(gocolorize.Green)
p2 = c.Paint
Fmt.Println(p("different" + " " + p2("colors")))
```
Object Properties:
```go
//These will only apply if there is a Fg and Bg respectively
c.ToggleFgIntensity()
c.ToggleBgIntensity()
//Set additional attributes
c.ToggleBold()
c.ToggleBlink()
c.ToggleUnderLine()
c.ToggleInverse()
//To disable or renable everything color (for example on Windows)
//the other functions will still work, they'll just return plain
//text for portability
gocolorize.SetPlain(true)
```
##NewColor String Format
```go
"foregroundColor+attributes:backgroundColor+attributes"
```
Colors:
* black
* red
* green
* yellow
* blue
* magenta
* cyan
* white
Attributes:
* b = bold foreground
* B = blink foreground
* u = underline foreground
* h = high intensity (bright) foreground, background
* i = inverse
##Examples
See examples directory for examples:
$ cd examples/
$ go run song.go
$ go run logging.go
##Tests
Tests are another good place to see examples. In order to run tests:
$ go test -cover
##Portability
ANSI coloring will not work in default Windows environments and may not work in other environments correctly. In order to allow compatibility with these environments, you can call:
```go
gocolorize.SetPlain(true)
```
Once toggled, the library will still function, but it will not color the output.

## Special Thanks
https://github.com/mgutz/ansi was an inspiration for the latest version. I did a lot of rewriting, removed the 'paints' module, and did a lot of general cleanup. I learned a lot reading this and using this code.

behalf of any Contributor. You must make it absolutely clear that any
such warranty, support, indemnity, or liability obligation is offered by
You alone, and You hereby agree to indemnify every Contributor for any
liability incurred by such Contributor as a result of warranty, support,
indemnity or liability terms You offer. You may include additional
disclaimers of warranty and limitations of liability specific to any
jurisdiction.
4. Inability to Comply Due to Statute or Regulation
If it is impossible for You to comply with any of the terms of this License
with respect to some or all of the Covered Software due to statute,
judicial order, or regulation then You must: (a) comply with the terms of
this License to the maximum extent possible; and (b) describe the
limitations and the code they affect. Such description must be placed in a
text file included with all distributions of the Covered Software under
this License. Except to the extent prohibited by statute or regulation,
such description must be sufficiently detailed for a recipient of ordinary
skill to be able to understand it.
5. Termination
5.1. The rights granted under this License will terminate automatically if You
fail to comply with any of its terms. However, if You become compliant,
then the rights granted under this License from a particular Contributor
are reinstated (a) provisionally, unless and until such Contributor
explicitly and finally terminates Your grants, and (b) on an ongoing
basis, if such Contributor fails to notify You of the non-compliance by
some reasonable means prior to 60 days after You have come back into
compliance. Moreover, Your grants from a particular Contributor are
reinstated on an ongoing basis if such Contributor notifies You of the
non-compliance by some reasonable means, this is the first time You have
received notice of non-compliance with this License from such
Contributor, and You become compliant prior to 30 days after Your receipt
of the notice.
5.2. If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions,
counter-claims, and cross-claims) alleging that a Contributor Version
directly or indirectly infringes any patent, then the rights granted to
You by any and all Contributors for the Covered Software under Section
2.1 of this License shall terminate.
5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
license agreements (excluding distributors and resellers) which have been
validly granted by You or Your distributors under this License prior to
termination shall survive termination.
6. Disclaimer of Warranty
Covered Software is provided under this License on an "as is" basis,
without warranty of any kind, either expressed, implied, or statutory,
including, without limitation, warranties that the Covered Software is free
of defects, merchantable, fit for a particular purpose or non-infringing.
The entire risk as to the quality and performance of the Covered Software
is with You. Should any Covered Software prove defective in any respect,
You (not any Contributor) assume the cost of any necessary servicing,
repair, or correction. This disclaimer of warranty constitutes an essential
part of this License. No use of any Covered Software is authorized under
this License except under this disclaimer.
7. Limitation of Liability
Under no circumstances and under no legal theory, whether tort (including
negligence), contract, or otherwise, shall any Contributor, or anyone who
distributes Covered Software as permitted above, be liable to You for any
direct, indirect, special, incidental, or consequential damages of any
character including, without limitation, damages for lost profits, loss of
goodwill, work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses, even if such party shall have been
informed of the possibility of such damages. This limitation of liability
shall not apply to liability for death or personal injury resulting from
such party's negligence to the extent applicable law prohibits such
limitation. Some jurisdictions do not allow the exclusion or limitation of
incidental or consequential damages, so this exclusion and limitation may
not apply to You.
8. Litigation
Any litigation relating to this License may be brought only in the courts
of a jurisdiction where the defendant maintains its principal place of
business and such litigation shall be governed by laws of that
jurisdiction, without reference to its conflict-of-law provisions. Nothing
in this Section shall prevent a party's ability to bring cross-claims or
counter-claims.
9. Miscellaneous
This License represents the complete agreement concerning the subject
matter hereof. If any provision of this License is held to be
unenforceable, such provision shall be reformed only to the extent
necessary to make it enforceable. Any law or regulation which provides that
the language of a contract shall be construed against the drafter shall not
be used to construe this License against a Contributor.
10. Versions of the License
10.1. New Versions
Mozilla Foundation is the license steward. Except as provided in Section
10.3, no one other than the license steward has the right to modify or
publish new versions of this License. Each version will be given a
distinguishing version number.
10.2. Effect of New Versions
You may distribute the Covered Software under the terms of the version
of the License under which You originally received the Covered Software,
or under the terms of any subsequent version published by the license
steward.
10.3. Modified Versions
If you create software not governed by this License, and you want to
create a new license for such software, you may create and use a
modified version of this License if you rename the license and remove
any references to the name of the license steward (except to note that
such modified license differs from this License).
10.4. Distributing Source Code Form that is Incompatible With Secondary
Licenses If You choose to distribute Source Code Form that is
Incompatible With Secondary Licenses under the terms of this version of
the License, the notice described in Exhibit B of this License must be

consul-api
==========
*DEPRECATED* Please use [consul api package](https://github.com/hashicorp/consul/tree/master/api) instead.
Godocs for that package [are here](http://godoc.org/github.com/hashicorp/consul/api).
This package provides the `consulapi` package which attempts to
provide programmatic access to the full Consul API.
Currently, all of the Consul APIs included in version 0.4 are supported.
Documentation
=============
The full documentation is available on [Godoc](http://godoc.org/github.com/armon/consul-api)
Usage
=====
Below is an example of using the Consul client:
```go
// Get a new client, with KV endpoints
client, _ := consulapi.NewClient(consulapi.DefaultConfig())
kv := client.KV()
// PUT a new KV pair
p := &consulapi.KVPair{Key: "foo", Value: []byte("test")}
_, err := kv.Put(p, nil)
if err != nil {
panic(err)
}
// Lookup the pair
pair, _, err := kv.Get("foo", nil)
if err != nil {
panic(err)
}
fmt.Printf("KV: %v", pair)
```

# Exponential Backoff [![GoDoc][godoc image]][godoc] [![Build Status][travis image]][travis]
This is a Go port of the exponential backoff algorithm from [Google's HTTP Client Library for Java][google-http-java-client].
[Exponential backoff][exponential backoff wiki]
is an algorithm that uses feedback to multiplicatively decrease the rate of some process,
in order to gradually find an acceptable rate.
The retries exponentially increase and stop increasing when a certain threshold is met.
## How To
We define two functions, `Retry()` and `RetryNotify()`.
They receive an `Operation` to execute, a `BackOff` algorithm,
and an optional `Notify` error handler.
The operation will be executed, and will be retried on failure with delay
as given by the backoff algorithm. The backoff algorithm can also decide when to stop
retrying.
In addition, the notify error handler will be called after each failed attempt,
except for the last time, whose error should be handled by the caller.
```go
// An Operation is executing by Retry() or RetryNotify().
// The operation will be retried using a backoff policy if it returns an error.
type Operation func() error
// Notify is a notify-on-error function. It receives an operation error and
// backoff delay if the operation failed (with an error).
//
// NOTE that if the backoff policy stated to stop retrying,
// the notify function isn't called.
type Notify func(error, time.Duration)
func Retry(Operation, BackOff) error
func RetryNotify(Operation, BackOff, Notify)
```
## Examples
See more advanced examples in the [godoc][advanced example].
### Retry
Simple retry helper that uses the default exponential backoff algorithm:
```go
operation := func() error {
// An operation that might fail.
return nil // or return errors.New("some error")
}
err := Retry(operation, NewExponentialBackOff())
if err != nil {
// Handle error.
return err
}
// Operation is successful.
return nil
```
### Ticker
```go
operation := func() error {
// An operation that might fail
return nil // or return errors.New("some error")
}
b := NewExponentialBackOff()
ticker := NewTicker(b)
var err error
// Ticks will continue to arrive when the previous operation is still running,
// so operations that take a while to fail could run in quick succession.
for range ticker.C {
if err = operation(); err != nil {
log.Println(err, "will retry...")
continue
}
ticker.Stop()
break
}
if err != nil {
// Operation has failed.
return err
}
// Operation is successful.
return nil
```

package backoff
import (

/*
ExponentialBackOff is a backoff implementation that increases the backoff
period for each retry attempt using a randomization function that grows exponentially.
NextBackOff() is calculated using the following formula:
randomized interval =
RetryInterval * (random value in range [1 - RandomizationFactor, 1 + RandomizationFactor])
In other words NextBackOff() will range between the randomization factor
percentage below and above the retry interval.
For example, given the following parameters:
RetryInterval = 2
RandomizationFactor = 0.5
Multiplier = 2
the actual backoff period used in the next retry attempt will range between 1 and 3 seconds,
multiplied by the exponential, that is, between 2 and 6 seconds.
Note: MaxInterval caps the RetryInterval and not the randomized interval.
If the time elapsed since an ExponentialBackOff instance is created goes past the
MaxElapsedTime, then the method NextBackOff() starts returning backoff.Stop.
The elapsed time can be reset by calling Reset().
Example: Given the following default arguments, for 10 tries the sequence will be,
and assuming we go over the MaxElapsedTime on the 10th try:
Request # RetryInterval (seconds) Randomized Interval (seconds)
1 0.5 [0.25, 0.75]
2 0.75 [0.375, 1.125]
3 1.125 [0.562, 1.687]
4 1.687 [0.8435, 2.53]
5 2.53 [1.265, 3.795]
6 3.795 [1.897, 5.692]
7 5.692 [2.846, 8.538]
8 8.538 [4.269, 12.807]
9 12.807 [6.403, 19.210]

High Performance, Feature-Rich Idiomatic Go codec/encoding library for

Supported Serialization formats are:
- msgpack: https://github.com/msgpack/msgpack

- cbor: http://cbor.io http://tools.ietf.org/html/rfc7049
- json: http://json.org http://tools.ietf.org/html/rfc7159
- simple:
To install:
go get github.com/ugorji/go/codec
This package understands the 'unsafe' tag, to allow using unsafe semantics:
- When decoding into a struct, you need to read the field name as a string
so you can find the struct field it is mapped to.
Using `unsafe` will bypass the allocation and copying overhead of []byte->string conversion.
To install using unsafe, pass the 'unsafe' tag:
go get -tags=unsafe github.com/ugorji/go/codec

The idiomatic Go support is as seen in other encoding packages in
the standard library (ie json, xml, gob, etc).
Rich Feature Set includes:
- Simple but extremely powerful and feature-rich API
- Very High Performance.
Our extensive benchmarks show us outperforming Gob, Json, Bson, etc by 2-4X.
- Multiple conversions:
Package coerces types where appropriate
e.g. decode an int in the stream into a float, etc.
- Corner Cases:
Overflows, nil maps/slices, nil values in streams are handled correctly
- Standard field renaming via tags
- Support for omitting empty fields during an encoding
- Encoding from any value and decoding into pointer to any value
(struct, slice, map, primitives, pointers, interface{}, etc)
- Extensions to support efficient encoding/decoding of any named types
- Support encoding.(Binary|Text)(M|Unm)arshaler interfaces
- Decoding without a schema (into a interface{}).
Includes Options to configure what specific map or slice type to use
when decoding an encoded list or map into a nil interface{}
- Encode a struct as an array, and decode struct from an array in the data stream
- Comprehensive support for anonymous fields
- Fast (no-reflection) encoding/decoding of common maps and slices
- Code-generation for faster performance.
- Support binary (e.g. messagepack, cbor) and text (e.g. json) formats
- Support indefinite-length formats to enable true streaming
(for formats which support it e.g. json, cbor)
- Support canonical encoding, where a value is ALWAYS encoded as same sequence of bytes.
This mostly applies to maps, where iteration order is non-deterministic.
- NIL in data stream decoded as zero value
- Never silently skip data when decoding.
User decides whether to return an error or silently skip data when keys or indexes
in the data stream do not map to fields in the struct.
- Encode/Decode from/to chan types (for iterative streaming support)
- Drop-in replacement for encoding/json. `json:` key in struct tag supported.
- Provides a RPC Server and Client Codec for net/rpc communication protocol.
- Handle unique idiosynchracies of codecs e.g.
- For messagepack, configure how ambiguities in handling raw bytes are resolved
- For messagepack, provide rpc server/client codec to support
msgpack-rpc protocol defined at:
https://github.com/msgpack-rpc/msgpack-rpc/blob/master/spec.md
Extension Support
Users can register a function to handle the encoding or decoding of
their custom types.
There are no restrictions on what the custom type can be. Some examples:
type BisSet []int
type BitSet64 uint64
type UUID string
type MyStructWithUnexportedFields struct { a int; b bool; c []int; }
type GifImage struct { ... }
As an illustration, MyStructWithUnexportedFields would normally be
encoded as an empty map because it has no exported fields, while UUID
would be encoded as a string. However, with extension support, you can
encode any of these however you like.
RPC
RPC Client and Server Codecs are implemented, so the codecs can be used
with the standard net/rpc package.
Usage
The Handle is SAFE for concurrent READ, but NOT SAFE for concurrent modification.
The Encoder and Decoder are NOT safe for concurrent use.
Consequently, the usage model is basically:
- Create and initialize the Handle before any use.
Once created, DO NOT modify it.
- Multiple Encoders or Decoders can now use the Handle concurrently.
They only read information off the Handle (never write).
- However, each Encoder or Decoder MUST not be used concurrently
- To re-use an Encoder/Decoder, call Reset(...) on it first.
This allows you use state maintained on the Encoder/Decoder.
Sample usage model:
// create and configure Handle
var (
bh codec.BincHandle
mh codec.MsgpackHandle
ch codec.CborHandle
)
mh.MapType = reflect.TypeOf(map[string]interface{}(nil))
// configure extensions
// e.g. for msgpack, define functions and enable Time support for tag 1
// mh.SetExt(reflect.TypeOf(time.Time{}), 1, myExt)
// create and use decoder/encoder
var (
r io.Reader
w io.Writer
b []byte
h = &bh // or mh to use msgpack
)
dec = codec.NewDecoder(r, h)
dec = codec.NewDecoderBytes(b, h)
err = dec.Decode(&v)
enc = codec.NewEncoder(w, h)
enc = codec.NewEncoderBytes(&b, h)
err = enc.Encode(v)
//RPC Server
go func() {
for {
conn, err := listener.Accept()
rpcCodec := codec.GoRpc.ServerCodec(conn, h)
//OR rpcCodec := codec.MsgpackSpecRpc.ServerCodec(conn, h)
rpc.ServeCodec(rpcCodec)
}
}()
//RPC Communication (client side)
conn, err = net.Dial("tcp", "localhost:5555")
rpcCodec := codec.GoRpc.ClientCodec(conn, h)
//OR rpcCodec := codec.MsgpackSpecRpc.ClientCodec(conn, h)
client := rpc.NewClientWithCodec(rpcCodec)
*/
package codec
// Benefits of go-codec:
//
// - encoding/json always reads whole file into memory first.
// This makes it unsuitable for parsing very large files.
// - encoding/xml cannot parse into a map[string]interface{}
// I found this out on reading https://github.com/clbanning/mxj
// TODO:
//
// - (En|De)coder should store an error when it occurs.
// Until reset, subsequent calls return that error that was stored.
// This means that free panics must go away.
// All errors must be raised through errorf method.
// - Decoding using a chan is good, but incurs concurrency costs.
// This is because there's no fast way to use a channel without it
// having to switch goroutines constantly.
// Callback pattern is still the best. Maybe cnsider supporting something like:
// type X struct {
// Name string
// Ys []Y
// Ys chan <- Y
// Ys func(interface{}) -> call this interface for each entry in there.
// }
// - Consider adding a isZeroer interface { isZero() bool }
// It is used within isEmpty, for omitEmpty support.
// - Consider making Handle used AS-IS within the encoding/decoding session.
// This means that we don't cache Handle information within the (En|De)coder,
// except we really need it at Reset(...)
// - Handle recursive types during encoding/decoding?

# Codec
High Performance, Feature-Rich Idiomatic Go codec/encoding library for
binc, msgpack, cbor, json.
Supported Serialization formats are:
- msgpack: https://github.com/msgpack/msgpack
- binc: http://github.com/ugorji/binc
- cbor: http://cbor.io http://tools.ietf.org/html/rfc7049
- json: http://json.org http://tools.ietf.org/html/rfc7159
- simple:
To install:
go get github.com/ugorji/go/codec
This package understands the `unsafe` tag, to allow using unsafe semantics:
- When decoding into a struct, you need to read the field name as a string
so you can find the struct field it is mapped to.
Using `unsafe` will bypass the allocation and copying overhead of `[]byte->string` conversion.
To use it, you must pass the `unsafe` tag during install:
```
go install -tags=unsafe github.com/ugorji/go/codec
```

// -------------------------
// CborHandle is a Handle for the CBOR encoding format,
// defined at http://tools.ietf.org/html/rfc7049 and documented further at http://cbor.io .
//
// CBOR is comprehensively supported, including support for:
// - indefinite-length arrays/maps/bytes/strings
// - (extension) tags in range 0..0xffff (0 .. 65535)
// - half, single and double-precision floats
// - all numbers (1, 2, 4 and 8-byte signed and unsigned integers)
// - nil, true, false, ...
// - arrays and maps, bytes and text strings
//
// None of the optional extensions (with tags) defined in the spec are supported out-of-the-box.
// Users can implement them as needed (using SetExt), including spec-documented ones:
// - timestamp, BigNum, BigFloat, Decimals, Encoded Text (e.g. URL, regexp, base64, MIME Message), etc.
//
// To encode with indefinite lengths (streaming), users will use
// (Must)Encode methods of *Encoder, along with writing CborStreamXXX constants.
//
// For example, to encode "one-byte" as an indefinite length string:
// var buf bytes.Buffer
// e := NewEncoder(&buf, new(CborHandle))
// buf.WriteByte(CborStreamString)
// e.MustEncode("one-")
// e.MustEncode("byte")
// buf.WriteByte(CborStreamBreak)
// encodedBytes := buf.Bytes()
// var vv interface{}
// NewDecoderBytes(buf.Bytes(), new(CborHandle)).MustDecode(&vv)
// // Now, vv contains the same string "one-byte"

package codec
// Fast path functions try to create a fast path encode or decode implementation
// for common maps and slices.
//
// We define the functions and register then in this single file
// so as not to pollute the encode.go and decode.go, and create a dependency in there.
// This file can be omitted without causing a build failure.
//
// The advantage of fast paths is:
// - Many calls bypass reflection altogether
//
// Currently support
// - slice of all builtin types,
// - map of all builtin types to string or interface value
// - symetrical maps of all builtin types (e.g. str-str, uint8-uint8)
// This should provide adequate "typical" implementations.
//
// Note that fast track decode functions must handle values for which an address cannot be obtained.
// For example:
// m2 := map[string]int{}
// p2 := []interface{}{m2}
// // decoding into p2 will bomb if fast track functions do not treat like unaddressable.

For compatibility with behaviour of msgpack-c reference implementation:
- Go intX (>0) and uintX
IS ENCODED AS
msgpack +ve fixnum, unsigned
- Go intX (<0)
IS ENCODED AS

//------------------------------------
// SimpleHandle is a Handle for a very simple encoding format.
//
// simple is a simplistic codec similar to binc, but not as compact.
// - Encoding of a value is always preceeded by the descriptor byte (bd)
// - True, false, nil are encoded fully in 1 byte (the descriptor)
// - Integers (intXXX, uintXXX) are encoded in 1, 2, 4 or 8 bytes (plus a descriptor byte).
// There are positive (uintXXX and intXXX >= 0) and negative (intXXX < 0) integers.
// - Floats are encoded in 4 or 8 bytes (plus a descriptor byte)
// - Lenght of containers (strings, bytes, array, map, extensions)
// are encoded in 0, 1, 2, 4 or 8 bytes.
// Zero-length containers have no length encoded.
// For others, the number of bytes is given by pow(2, bd%3)
// - maps are encoded as [bd] [length] [[key][value]]...
// - arrays are encoded as [bd] [length] [value]...
// - extensions are encoded as [bd] [length] [tag] [byte]...
// - strings/bytearrays are encoded as [bd] [length] [byte]...
//
// The full spec will be published soon.

// EncodeTime encodes a time.Time as a []byte, including
// information on the instant in time and UTC offset.
//
// Format Description
//
// A timestamp is composed of 3 components:
//
// - secs: signed integer representing seconds since unix epoch
// - nsces: unsigned integer representing fractional seconds as a
// nanosecond offset within secs, in the range 0 <= nsecs < 1e9
// - tz: signed integer representing timezone offset in minutes east of UTC,
// and a dst (daylight savings time) flag
//
// When encoding a timestamp, the first byte is the descriptor, which
// defines which components are encoded and how many bytes are used to
// encode secs and nsecs components. *If secs/nsecs is 0 or tz is UTC, it
// is not encoded in the byte array explicitly*.
//
// Descriptor 8 bits are of the form `A B C DDD EE`:
// A: Is secs component encoded? 1 = true
// B: Is nsecs component encoded? 1 = true
// C: Is tz component encoded? 1 = true
// DDD: Number of extra bytes for secs (range 0-7).
// If A = 1, secs encoded in DDD+1 bytes.
// If A = 0, secs is not encoded, and is assumed to be 0.
// If A = 1, then we need at least 1 byte to encode secs.
// DDD says the number of extra bytes beyond that 1.
// E.g. if DDD=0, then secs is represented in 1 byte.
// if DDD=2, then secs is represented in 3 bytes.
// EE: Number of extra bytes for nsecs (range 0-3).
// If B = 1, nsecs encoded in EE+1 bytes (similar to secs/DDD above)
//
// Following the descriptor bytes, subsequent bytes are:
//
// secs component encoded in `DDD + 1` bytes (if A == 1)
// nsecs component encoded in `EE + 1` bytes (if B == 1)
// tz component encoded in 2 bytes (if C == 1)
//
// secs and nsecs components are integers encoded in a BigEndian
// 2-complement encoding format.
//
// tz component is encoded as 2 bytes (16 bits). Most significant bit 15 to
// Least significant bit 0 are described below:
//
// Timezone offset has a range of -12:00 to +14:00 (ie -720 to +840 minutes).
// Bit 15 = have\_dst: set to 1 if we set the dst flag.
// Bit 14 = dst\_on: set to 1 if dst is in effect at the time, or 0 if not.
// Bits 13..0 = timezone offset in minutes. It is a signed integer in Big Endian format.

# etcd/client
etcd/client is the Go client library for etcd.
[![GoDoc](https://godoc.org/github.com/coreos/etcd/client?status.png)](https://godoc.org/github.com/coreos/etcd/client)
## Install
```bash
go get github.com/coreos/etcd/client
```
## Usage
```go
package main
import (
"log"
"time"
"github.com/coreos/etcd/Godeps/_workspace/src/golang.org/x/net/context"
"github.com/coreos/etcd/client"
)
func main() {
cfg := client.Config{
Endpoints: []string{"http://127.0.0.1:2379"},
Transport: client.DefaultTransport,
// set timeout per request to fail fast when the target endpoint is unavailable
HeaderTimeoutPerRequest: time.Second,
}
c, err := client.New(cfg)
if err != nil {
log.Fatal(err)
}
kapi := client.NewKeysAPI(c)
// set "/foo" key with "bar" value
log.Print("Setting '/foo' key with 'bar' value")
resp, err := kapi.Set(context.Background(), "/foo", "bar", nil)
if err != nil {
log.Fatal(err)
} else {
// print common key info
log.Printf("Set is done. Metadata is %q\n", resp)
}
// get "/foo" key's value
log.Print("Getting '/foo' key value")
resp, err = kapi.Get(context.Background(), "/foo", nil)
if err != nil {
log.Fatal(err)
} else {
// print common key info
log.Printf("Get is done. Metadata is %q\n", resp)
// print value
log.Printf("%q key has %q value\n", resp.Node.Key, resp.Node.Value)
}
}
```
## Error Handling
etcd client might return three types of errors.
- context error
Each API call has its first parameter as `context`. A context can be canceled or have an attached deadline. If the context is canceled or reaches its deadline, the responding context error will be returned no matter what internal errors the API call has already encountered.
- cluster error
Each API call tries to send request to the cluster endpoints one by one until it successfully gets a response. If a requests to an endpoint fails, due to exceeding per request timeout or connection issues, the error will be added into a list of errors. If all possible endpoints fail, a cluster error that includes all encountered errors will be returned.
- response error
If the response gets from the cluster is invalid, a plain string error will be returned. For example, it might be a invalid JSON error.
Here is the example code to handle client errors:
```go
cfg := client.Config{Endpoints: []string{"http://etcd1:2379","http://etcd2:2379","http://etcd3:2379"}}
c, err := client.New(cfg)
if err != nil {
log.Fatal(err)
}
kapi := client.NewKeysAPI(c)
resp, err := kapi.Set(ctx, "test", "bar", nil)
if err != nil {
if err == context.Canceled {
// ctx is canceled by another routine
} else if err == context.DeadlineExceeded {
// ctx is attached with a deadline and it exceeded
} else if cerr, ok := err.(*client.ClusterError); ok {
// process (cerr.Errors)
} else {
// bad cluster endpoints, which are not etcd servers
}
}
```
## Caveat
1. etcd/client prefers to use the same endpoint as long as the endpoint continues to work well. This saves socket resources, and improves efficiency for both client and server side. This preference doesn't remove consistency from the data consumed by the client because data replicated to each etcd member has already passed through the consensus process.
2. etcd/client does round-robin rotation on other available endpoints if the preferred endpoint isn't functioning properly. For example, if the member that etcd/client connects to is hard killed, etcd/client will fail on the first attempt with the killed member, and succeed on the second attempt with another member. If it fails to talk to all available endpoints, it will return all errors happened.
3. Default etcd/client cannot handle the case that the remote server is SIGSTOPed now. TCP keepalive mechanism doesn't help in this scenario because operating system may still send TCP keep-alive packets. Over time we'd like to improve this functionality, but solving this issue isn't high priority because a real-life case in which a server is stopped, but the connection is kept alive, hasn't been brought to our attention.
4. etcd/client cannot detect whether the member in use is healthy when doing read requests. If the member is isolated from the cluster, etcd/client may retrieve outdated data. As a workaround, users could monitor experimental /health endpoint for member healthy information. We are improving it at [#3265](https://github.com/coreos/etcd/issues/3265).

Package client provides bindings for the etcd APIs.
Create a Config and exchange it for a Client:
import (
"net/http"
"github.com/coreos/etcd/client"
"golang.org/x/net/context"
)
cfg := client.Config{
Endpoints: []string{"http://127.0.0.1:2379"},
Transport: DefaultTransport,
}
c, err := client.New(cfg)
if err != nil {
// handle error
}
Create a KeysAPI using the Client, then use it to interact with etcd:
kAPI := client.NewKeysAPI(c)
// create a new key /foo with the value "bar"
_, err = kAPI.Create(context.Background(), "/foo", "bar")
if err != nil {
// handle error
}
// delete the newly created key only if the value is still "bar"
_, err = kAPI.Delete(context.Background(), "/foo", &DeleteOptions{PrevValue: "bar"})
if err != nil {
// handle error
}
Use a custom context to set timeouts on your operations:
import "time"
ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
defer cancel()
// set a new key, ignoring it's previous state
_, err := kAPI.Set(ctx, "/ping", "pong", nil)
if err != nil {
if err == context.DeadlineExceeded {
// request took longer than 5s
} else {
// handle error
}
}
