of their Contribution(s) with the Work to which such Contribution(s) was
submitted. If You institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work or a
Contribution incorporated within the Work constitutes direct or contributory
patent infringement, then any patent licenses granted to You under this License
for that Work shall terminate as of the date such litigation is filed.

Works, if and wherever such third-party notices normally appear. The contents of
the NOTICE file are for informational purposes only and do not modify the
License. You may add Your own attribution notices within Derivative Works that
You distribute, alongside or as an addendum to the NOTICE text from the Work,
provided that such additional attribution notices cannot be construed as
modifying the License.
You may add Your own copyright statement to Your modifications and may provide
additional or different license terms and conditions for use, reproduction, or
distribution of Your modifications, or for any such Derivative Works as a whole,
provided Your use, reproduction, and distribution of the Work otherwise complies
with the conditions stated in this License.

liable to You for damages, including any direct, indirect, special, incidental,
or consequential damages of any character arising as a result of this License or
out of the use or inability to use the Work (including but not limited to
damages for loss of goodwill, work stoppage, computer failure or malfunction, or
any and all other commercial damages or losses), even if such Contributor has
been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability.
While redistributing the Work or Derivative Works thereof, You may choose to
offer, and charge a fee for, acceptance of support, warranty, indemnity, or
other liability obligations and/or rights consistent with this License. However,
in accepting such obligations, You may act only on Your own behalf and on Your
sole responsibility, not on behalf of any other Contributor, and only if You
agree to indemnify, defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason of your
accepting any such warranty or additional liability.

# capnslog, the CoreOS logging package
There are far too many logging packages out there, with varying degrees of licenses, far too many features (colorization, all sorts of log frameworks) or are just a pain to use (lack of `Fatalln()`?).
capnslog provides a simple but consistent logging interface suitable for all kinds of projects.
### Design Principles
##### `package main` is the place where logging gets turned on and routed
A library should not touch log options, only generate log entries. Libraries are silent until main lets them speak.
##### All log options are runtime-configurable.
Still the job of `main` to expose these configurations. `main` may delegate this to, say, a configuration webhook, but does so explicitly.
##### There is one log object per package. It is registered under its repository and package name.
`main` activates logging for its repository and any dependency repositories it would also like to have output in its logstream. `main` also dictates at which level each subpackage logs.
##### There is *one* output stream, and it is an `io.Writer` composed with a formatter.
Splitting streams is probably not the job of your program, but rather, your log aggregation framework. If you must split output streams, again, `main` configures this and you can write a very simple two-output struct that satisfies io.Writer.
Fancy colorful formatting and JSON output are beyond the scope of a basic logging framework -- they're application/log-collector dependant. These are, at best, provided as options, but more likely, provided by your application.
##### Log objects are an interface
An object knows best how to print itself. Log objects can collect more interesting metadata if they wish, however, because text isn't going away anytime soon, they must all be marshalable to text. The simplest log object is a string, which returns itself. If you wish to do more fancy tricks for printing your log objects, see also JSON output -- introspect and write a formatter which can handle your advanced log interface. Making strings is the only thing guaranteed.
##### Log levels have specific meanings:
* Critical: Unrecoverable. Must fail.
* Error: Data has been lost, a request has failed for a bad reason, or a required resource has been lost
* Warning: (Hopefully) Temporary conditions that may cause errors, but may work fine. A replica disappearing (that may reconnect) is a warning.
* Notice: Normal, but important (uncommon) log information.
* Info: Normal, working log information, everything is fine, but helpful notices for auditing or common operations.
* Debug: Everything is still fine, but even common operations may be logged, and less helpful but more quantity of notices.
* Trace: Anything goes, from logging every function call as part of a common operation, to tracing execution of a query.

Package gogoproto provides extensions for protocol buffers to achieve:
- fast marshalling and unmarshalling.
- peace of mind by optionally generating test and benchmark code.
- more canonical Go structures.
- less typing by optionally generating extra helper code.
- goprotobuf compatibility
More Canonical Go Structures
A lot of time working with a goprotobuf struct will lead you to a place where you create another struct that is easier to work with and then have a function to copy the values between the two structs.
You might also find that basic structs that started their life as part of an API need to be sent over the wire. With gob, you could just send it. With goprotobuf, you need to make a parallel struct.
Gogoprotobuf tries to fix these problems with the nullable, embed, customtype and customname field extensions.
- nullable, if false, a field is generated without a pointer (see warning below).
- embed, if true, the field is generated as an embedded field.
- customtype, It works with the Marshal and Unmarshal methods, to allow you to have your own types in your struct, but marshal to bytes. For example, custom.Uuid or custom.Fixed128
- customname (beta), Changes the generated fieldname. This is especially useful when generated methods conflict with fieldnames.
- casttype (beta), Changes the generated fieldtype. All generated code assumes that this type is castable to the protocol buffer field type. It does not work for structs or enums.
- castkey (beta), Changes the generated fieldtype for a map key. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps.
- castvalue (beta), Changes the generated fieldtype for a map value. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps.
Warning about nullable: According to the Protocol Buffer specification, you should be able to tell whether a field is set or unset. With the option nullable=false this feature is lost, since your non-nullable fields will always be set. It can be seen as a layer on top of Protocol Buffers, where before and after marshalling all non-nullable fields are set and they cannot be unset.
Let us look at:
github.com/gogo/protobuf/test/example/example.proto
for a quicker overview.
The following message:
package test;
import "github.com/gogo/protobuf/gogoproto/gogo.proto";
message A {
optional string Description = 1 [(gogoproto.nullable) = false];
optional int64 Number = 2 [(gogoproto.nullable) = false];
optional bytes Id = 3 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uuid", (gogoproto.nullable) = false];
}
Will generate a go struct which looks a lot like this:
type A struct {
Description string
Number int64
Id github_com_gogo_protobuf_test_custom.Uuid
}
You will see there are no pointers, since all fields are non-nullable.
You will also see a custom type which marshals to a string.
Be warned it is your responsibility to test your custom types thoroughly.
You should think of every possible empty and nil case for your marshaling, unmarshaling and size methods.
Next we will embed the message A in message B.
message B {
optional A A = 1 [(gogoproto.nullable) = false, (gogoproto.embed) = true];
repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false];
}
See below that A is embedded in B.
type B struct {
A
G []github_com_gogo_protobuf_test_custom.Uint128
}
Also see the repeated custom type.
type Uint128 [2]uint64
Next we will create a custom name for one of our fields.
message C {
optional int64 size = 1 [(gogoproto.customname) = "MySize"];
}
See below that the field's name is MySize and not Size.
type C struct {
MySize *int64
}
The is useful when having a protocol buffer message with a field name which conflicts with a generated method.
As an example, having a field name size and using the sizer plugin to generate a Size method will cause a go compiler error.
Using customname you can fix this error without changing the field name.
This is typically useful when working with a protocol buffer that was designed before these methods and/or the go language were avialable.
Gogoprotobuf also has some more subtle changes, these could be changed back:
- the generated package name for imports do not have the extra /filename.pb,
but are actually the imports specified in the .proto file.
Gogoprotobuf also has lost some features which should be brought back with time:
- Marshalling and unmarshalling with reflect and without the unsafe package,
this requires work in pointer_reflect.go
Why does nullable break protocol buffer specifications:
The protocol buffer specification states, somewhere, that you should be able to tell whether a
field is set or unset. With the option nullable=false this feature is lost,
since your non-nullable fields will always be set. It can be seen as a layer on top of
protocol buffers, where before and after marshalling all non-nullable fields are set
and they cannot be unset.
Goprotobuf Compatibility:
Gogoprotobuf is compatible with Goprotobuf, because it is compatible with protocol buffers.
Gogoprotobuf generates the same code as goprotobuf if no extensions are used.
The enumprefix, getters and stringer extensions can be used to remove some of the unnecessary code generated by goprotobuf:
- gogoproto_import, if false, the generated code imports github.com/golang/protobuf/proto instead of github.com/gogo/protobuf/proto.
- goproto_enum_prefix, if false, generates the enum constant names without the messagetype prefix
- goproto_enum_stringer (experimental), if false, the enum is generated without the default string method, this is useful for rather using enum_stringer, or allowing you to write your own string method.
- goproto_getters, if false, the message is generated without get methods, this is useful when you would rather want to use face
- goproto_stringer, if false, the message is generated without the default string method, this is useful for rather using stringer, or allowing you to write your own string method.
- goproto_extensions_map (beta), if false, the extensions field is generated as type []byte instead of type map[int32]proto.Extension
- goproto_unrecognized (beta), if false, XXX_unrecognized field is not generated. This is useful in conjunction with gogoproto.nullable=false, to generate structures completely devoid of pointers and reduce GC pressure at the cost of losing information about unrecognized fields.
- goproto_registration (beta), if true, the generated files will register all messages and types against both gogo/protobuf and golang/protobuf. This is necessary when using third-party packages which read registrations from golang/protobuf (such as the grpc-gateway).
Less Typing and Peace of Mind is explained in their specific plugin folders godoc:
- github.com/gogo/protobuf/plugin/<extension_name>
If you do not use any of these extension the code that is generated
will be the same as if goprotobuf has generated it.
The most complete way to see examples is to look at
github.com/gogo/protobuf/test/thetest.proto
Gogoprototest is a seperate project,
because we want to keep gogoprotobuf independent of goprotobuf,
but we still want to test it thoroughly.

Equal returns true iff protocol buffers a and b are equal.
The arguments must both be pointers to protocol buffer structs.
Equality is defined in this way:
- Two messages are equal iff they are the same type,
corresponding fields are equal, unknown field sets
are equal, and extensions sets are equal.
- Two set scalar fields are equal iff their values are equal.
If the fields are of a floating-point type, remember that
NaN != x for all x, including NaN. If the message is defined
in a proto3 .proto file, fields are not "set"; specifically,
zero length proto3 "bytes" fields are equal (nil == {}).
- Two repeated fields are equal iff their lengths are the same,
and their corresponding elements are equal. Note a "bytes" field,
although represented by []byte, is not a repeated field and the
rule for the scalar fields described above applies.
- Two unset fields are equal.
- Two unknown field sets are equal if their current
encoded state is equal.
- Two extension sets are equal iff they have corresponding
elements that are pairwise equal.
- Two map fields are equal iff their lengths are the same,
and they contain the same set of elements. Zero-length map
fields are equal.
- Every other combination of things are not equal.
The return value is undefined if a and b are not protocol buffers.

/*
Package proto converts data structures to and from the wire format of
protocol buffers. It works in concert with the Go source code generated
for .proto files by the protocol compiler.
A summary of the properties of the protocol buffer interface
for a protocol buffer variable v:
- Names are turned from camel_case to CamelCase for export.
- There are no methods on v to set fields; just treat
them as structure fields.
- There are getters that return a field's value if set,
and return the field's default value if unset.
The getters work even if the receiver is a nil message.
- The zero value for a struct is its correct initialization state.
All desired fields must be set before marshaling.
- A Reset() method will restore a protobuf struct to its zero state.
- Non-repeated fields are pointers to the values; nil means unset.
That is, optional or required field int32 f becomes F *int32.
- Repeated fields are slices.
- Helper functions are available to aid the setting of fields.
msg.Foo = proto.String("hello") // set field
- Constants are defined to hold the default values of all fields that
have them. They have the form Default_StructName_FieldName.
Because the getter methods handle defaulted values,
direct use of these constants should be rare.
- Enums are given type names and maps from names to values.
Enum values are prefixed by the enclosing message's name, or by the
enum's type name if it is a top-level enum. Enum types have a String
method, and a Enum method to assist in message construction.
- Nested messages, groups and enums have type names prefixed with the name of
the surrounding message type.
- Extensions are given descriptor names that start with E_,
followed by an underscore-delimited list of the nested messages
that contain it (if any) followed by the CamelCased name of the
extension field itself. HasExtension, ClearExtension, GetExtension
and SetExtension are functions for manipulating extensions.
- Oneof field sets are given a single field in their message,
with distinguished wrapper types for each possible field value.
- Marshal and Unmarshal are functions to encode and decode the wire format.
When the .proto file specifies `syntax="proto3"`, there are some differences:
- Non-repeated fields of non-message type are values instead of pointers.
- Enum types do not get an Enum method.
The simplest way to describe this is to see an example.
Given file test.proto, containing
package example;
enum FOO { X = 17; }
message Test {
required string label = 1;
optional int32 type = 2 [default=77];
repeated int64 reps = 3;

# uuid ![build status](https://travis-ci.org/google/uuid.svg?branch=master)
The uuid package generates and inspects UUIDs based on
[RFC 4122](http://tools.ietf.org/html/rfc4122)
and DCE 1.1: Authentication and Security Services.
This package is based on the github.com/pborman/uuid package (previously named
code.google.com/p/go-uuid). It differs from these earlier packages in that
a UUID is a 16 byte array rather than a byte slice. One loss due to this
change is the ability to represent an invalid UUID (vs a NIL UUID).
###### Install
`go get github.com/google/uuid`
###### Documentation
[![GoDoc](https://godoc.org/github.com/google/uuid?status.svg)](http://godoc.org/github.com/google/uuid)
Full `go doc` style documentation for the package can be viewed online without

# etcd/clientv3
[![Docs](https://readthedocs.org/projects/etcd/badge/?version=latest&style=flat-square)](https://etcd.readthedocs.io/en/latest/?badge=latest)
[![Godoc](https://img.shields.io/badge/go-documentation-blue.svg?style=flat-square)](https://godoc.org/go.etcd.io/etcd/clientv3)
`etcd/clientv3` is the official Go etcd client for v3.
See https://etcd.readthedocs.io/en/latest for latest client architecture.
## Install
```bash
go get go.etcd.io/etcd/clientv3
```
## Get started
Create client using `clientv3.New`:
```go
cli, err := clientv3.New(clientv3.Config{
Endpoints: []string{"localhost:2379", "localhost:22379", "localhost:32379"},
DialTimeout: 5 * time.Second,
})
if err != nil {
// handle error!
}
defer cli.Close()
```
etcd v3 uses [`gRPC`](http://www.grpc.io) for remote procedure calls. And `clientv3` uses
[`grpc-go`](https://github.com/grpc/grpc-go) to connect to etcd. Make sure to close the client after using it.
If the client is not closed, the connection will have leaky goroutines. To specify client request timeout,
pass `context.WithTimeout` to APIs:
```go
ctx, cancel := context.WithTimeout(context.Background(), timeout)
resp, err := cli.Put(ctx, "sample_key", "sample_value")
cancel()
if err != nil {
// handle error!
}
// use the response
```
For full compatibility, it is recommended to vendor builds using etcd's vendored packages, using tools like `golang/dep`, as in [vendor directories](https://golang.org/cmd/go/#hdr-Vendor_Directories).
## Error Handling
etcd client returns 2 types of errors:
1. context error: canceled or deadline exceeded.
2. gRPC error: see [api/v3rpc/rpctypes](https://godoc.org/go.etcd.io/etcd/etcdserver/api/v3rpc/rpctypes).
Here is the example code to handle client errors:
```go
resp, err := cli.Put(ctx, "", "")
if err != nil {
switch err {
case context.Canceled:
log.Fatalf("ctx is canceled by another routine: %v", err)
case context.DeadlineExceeded:
log.Fatalf("ctx is attached with a deadline is exceeded: %v", err)
case rpctypes.ErrEmptyKey:
log.Fatalf("client-side error: %v", err)
default:
log.Fatalf("bad cluster endpoints, which are not etcd servers: %v", err)
}
}
```
## Metrics
The etcd client optionally exposes RPC metrics through [go-grpc-prometheus](https://github.com/grpc-ecosystem/go-grpc-prometheus). See the [examples](https://github.com/etcd-io/etcd/blob/master/clientv3/example_metrics_test.go).
## Namespacing
The [namespace](https://godoc.org/go.etcd.io/etcd/clientv3/namespace) package provides `clientv3` interface wrappers to transparently isolate client requests to a user-defined prefix.
## Request size limit
Client request size limit is configurable via `clientv3.Config.MaxCallSendMsgSize` and `MaxCallRecvMsgSize` in bytes. If none given, client request send limit defaults to 2 MiB including gRPC overhead bytes. And receive limit defaults to `math.MaxInt32`.
## Examples
More code examples can be found at [GoDoc](https://godoc.org/go.etcd.io/etcd/clientv3).
