# Intel GPU Device Plugin for Kubernetes
## QuickStart: build and run plugin on the host
### Prerequisites
- Computer with supported Intel GPU device running Linux
- Fully configured kubernetes node joined to the cluster
- Working [Go environment]
- Read access to the [Intel device plugins] git repository
### Get source code
```
$ mkdir -p $GOPATH/src/github.com/intel/
$ cd $GOPATH/src/github.com/intel/
$ git clone https://github.com/intel/intel-device-plugins-for-kubernetes.git
```
### Build device plugin
```
$ cd $GOPATH/src/github.com/intel/intel-device-plugins-for-kubernetes
$ make
```
The result plugin executable is **cmd/gpu_plugin/gpu_plugin**
### Configure kubelet
This instruction has been written with the assumption that the target
Kubernetes cluster is installed and configured with the `kubeadm` toolkit
from the official packages from http://kubernetes.io and the latest
tested version of Kubernetes is 1.9.
- Add DevicePlugins=true to the kubelet command line option --feature-gates
This can be done by creating a systemd drop-in for kubelet service in /etc/systemd/system/kubelet.service.d/
with the following content:
```
[Service]
Environment="KUBELET_EXTRA_ARGS=--feature-gates='DevicePlugins=true,HugePages=true'"
```
Check the man page for `systemd.unit` for more details on systemd drop-ins.
- Restart kubelet service with the new options
```
$ systemctl restart kubelet
```
- Make sure kubelet socket exists in /var/lib/kubelet/device-plugins/
```
$ ls /var/lib/kubelet/device-plugins/kubelet.sock
/var/lib/kubelet/device-plugins/kubelet.sock
```
### Run the plugin as administrator
```
$ sudo $GOPATH/src/github.com/intel/intel-device-plugins-for-kubernetes/cmd/gpu_plugin/gpu_plugin
GPU device plugin started
Adding '/dev/dri/card0' to GPU 'card0'
Adding '/dev/dri/controlD64' to GPU 'card0'
Adding '/dev/dri/renderD128' to GPU 'card0'
device-plugin start server at: /var/lib/kubelet/device-plugins/intelGPU.sock
device-plugin registered
device-plugin: ListAndWatch start
ListAndWatch: send devices &ListAndWatchResponse{Devices:[&Device{ID:card0,Health:Healthy,}],}
```
### Check if the plugin is registered on master
```
$ kubectl describe node <node name> | grep intel.com/gpu
intel.com/gpu: 1
intel.com/gpu: 1
```
There are more sophisticated ways to run device plugins. Please, consider reading [Device plugin deployment] to understand how to do it.
### Testing
1. Build a Docker image with beignet unit tests:
```
$ cd demo
$ ./build-image.sh ubuntu-demo-opencl
```
This command will produce a Docker image named `ubuntu-demo-opencl`.
2. Create a pod running unit tests off the local Docker image:
```
$ kubectl apply -f demo/intelgpu_pod.yaml
```
3. Observe the pod's logs:
```
$ kubectl logs intelgpu-demo-pod
```

GoGoProtobuf http://github.com/gogo/protobuf extends
GoProtobuf http://github.com/golang/protobuf
# Go support for Protocol Buffers
Google's data interchange format.
Copyright 2010 The Go Authors.
https://github.com/golang/protobuf
This package and the code it generates requires at least Go 1.4.
This software implements Go bindings for protocol buffers. For
information about protocol buffers themselves, see
https://developers.google.com/protocol-buffers/
## Installation ##
To use this software, you must:
- Install the standard C++ implementation of protocol buffers from
https://developers.google.com/protocol-buffers/
- Of course, install the Go compiler and tools from
https://golang.org/
See
https://golang.org/doc/install
for details or, if you are using gccgo, follow the instructions at
https://golang.org/doc/install/gccgo
- Grab the code from the repository and install the proto package.
The simplest way is to run `go get -u github.com/golang/protobuf/protoc-gen-go`.
The compiler plugin, protoc-gen-go, will be installed in $GOBIN,
defaulting to $GOPATH/bin. It must be in your $PATH for the protocol
compiler, protoc, to find it.
This software has two parts: a 'protocol compiler plugin' that
generates Go source files that, once compiled, can access and manage
protocol buffers; and a library that implements run-time support for
encoding (marshaling), decoding (unmarshaling), and accessing protocol
buffers.
There is support for gRPC in Go using protocol buffers.
See the note at the bottom of this file for details.
There are no insertion points in the plugin.
GoGoProtobuf provides extensions for protocol buffers and GoProtobuf
see http://github.com/gogo/protobuf/gogoproto/doc.go
## Using protocol buffers with Go ##
Once the software is installed, there are two steps to using it.
First you must compile the protocol buffer definitions and then import
them, with the support library, into your program.
To compile the protocol buffer definition, run protoc with the --gogo_out
parameter set to the directory you want to output the Go code to.
protoc --gogo_out=. *.proto
The generated files will be suffixed .pb.go. See the Test code below
for an example using such a file.
The package comment for the proto library contains text describing
the interface provided in Go for protocol buffers. Here is an edited
version.
If you are using any gogo.proto extensions you will need to specify the
proto_path to include the descriptor.proto and gogo.proto.
gogo.proto is located in github.com/gogo/protobuf/gogoproto
This should be fine, since your import is the same.
descriptor.proto is located in either github.com/gogo/protobuf/protobuf
or code.google.com/p/protobuf/trunk/src/
Its import is google/protobuf/descriptor.proto so it might need some help.
protoc --gogo_out=. -I=.:github.com/gogo/protobuf/protobuf *.proto
==========
The proto package 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.
Helpers for getting values are superseded by the
GetFoo methods and their use is deprecated.
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 with the enum's type name. Enum types have
a String method, and a Enum method to assist in message construction.
- Nested 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.
Consider file test.proto, containing
```proto
package example;
enum FOO { X = 17; };
message Test {
required string label = 1;
optional int32 type = 2 [default=77];
repeated int64 reps = 3;
optional group OptionalGroup = 4 {
required string RequiredField = 5;
}
}
```
To create and play with a Test object from the example package,
```go
package main
import (
"log"
"github.com/gogo/protobuf/proto"
"path/to/example"
)
func main() {
test := &example.Test {
Label: proto.String("hello"),
Type: proto.Int32(17),
Reps: []int64{1, 2, 3},
Optionalgroup: &example.Test_OptionalGroup {
RequiredField: proto.String("good bye"),
},
}
data, err := proto.Marshal(test)
if err != nil {
log.Fatal("marshaling error: ", err)
}
newTest := &example.Test{}
err = proto.Unmarshal(data, newTest)
if err != nil {
log.Fatal("unmarshaling error: ", err)
}
// Now test and newTest contain the same data.
if test.GetLabel() != newTest.GetLabel() {
log.Fatalf("data mismatch %q != %q", test.GetLabel(), newTest.GetLabel())
}
// etc.
}
```
## Parameters ##
To pass extra parameters to the plugin, use a comma-separated
parameter list separated from the output directory by a colon:
protoc --gogo_out=plugins=grpc,import_path=mypackage:. *.proto
- `import_prefix=xxx` - a prefix that is added onto the beginning of
all imports. Useful for things like generating protos in a
subdirectory, or regenerating vendored protobufs in-place.
- `import_path=foo/bar` - used as the package if no input files
declare `go_package`. If it contains slashes, everything up to the
rightmost slash is ignored.
- `plugins=plugin1+plugin2` - specifies the list of sub-plugins to
load. The only plugin in this repo is `grpc`.
- `Mfoo/bar.proto=quux/shme` - declares that foo/bar.proto is
associated with Go package quux/shme. This is subject to the
import_prefix parameter.
## gRPC Support ##
If a proto file specifies RPC services, protoc-gen-go can be instructed to
generate code compatible with gRPC (http://www.grpc.io/). To do this, pass
the `plugins` parameter to protoc-gen-go; the usual way is to insert it into
the --go_out argument to protoc:
protoc --gogo_out=plugins=grpc:. *.proto
## Compatibility ##
The library and the generated code are expected to be stable over time.
However, we reserve the right to make breaking changes without notice for the
following reasons:
- Security. A security issue in the specification or implementation may come to
light whose resolution requires breaking compatibility. We reserve the right
to address such security issues.
- Unspecified behavior. There are some aspects of the Protocol Buffers
specification that are undefined. Programs that depend on such unspecified
behavior may break in future releases.
- Specification errors or changes. If it becomes necessary to address an
inconsistency, incompleteness, or change in the Protocol Buffers
specification, resolving the issue could affect the meaning or legality of
existing programs. We reserve the right to address such issues, including
updating the implementations.
- Bugs. If the library has a bug that violates the specification, a program
that depends on the buggy behavior may break if the bug is fixed. We reserve
the right to fix such bugs.
- Adding methods or fields to generated structs. These may conflict with field
names that already exist in a schema, causing applications to break. When the
code generator encounters a field in the schema that would collide with a
generated field or method name, the code generator will append an underscore
to the generated field or method name.
- Adding, removing, or changing methods or fields in generated structs that
start with `XXX`. These parts of the generated code are exported out of
necessity, but should not be considered part of the public API.
- Adding, removing, or changing unexported symbols in generated code.
Any breaking changes outside of these will be announced 6 months in advance to
protobuf@googlegroups.com.
You should, whenever possible, use generated code created by the `protoc-gen-go`
tool built at the same commit as the `proto` package. The `proto` package
declares package-level constants in the form `ProtoPackageIsVersionX`.
Application code and generated code may depend on one of these constants to
ensure that compilation will fail if the available version of the proto library
is too old. Whenever we make a change to the generated code that requires newer
library support, in the same commit we will increment the version number of the
generated code and declare a new package-level constant whose name incorporates
the latest version number. Removing a compatibility constant is considered a
breaking change and would be subject to the announcement policy stated above.
## Plugins ##
The `protoc-gen-go/generator` package exposes a plugin interface,
which is used by the gRPC code generation. This interface is not
supported and is subject to incompatible changes without notice.

# Protocol Buffers for Go with Gadgets
[![Build Status](https://travis-ci.org/gogo/protobuf.svg?branch=master)](https://travis-ci.org/gogo/protobuf)
gogoprotobuf is a fork of <a href="https://github.com/golang/protobuf">golang/protobuf</a> with extra code generation features.
This code generation is used to achieve:
- fast marshalling and unmarshalling
- more canonical Go structures
- goprotobuf compatibility
- less typing by optionally generating extra helper code
- peace of mind by optionally generating test and benchmark code
- other serialization formats
Keeping track of how up to date gogoprotobuf is relative to golang/protobuf is done in this

## Getting Started
There are several ways to use gogoprotobuf, but for all you need to install go and protoc.
After that you can choose:
- Speed
- More Speed and more generated code
- Most Speed and most customization
### Installation
To install it, you must first have Go (at least version 1.6.3) installed (see [http://golang.org/doc/install](http://golang.org/doc/install)). Go 1.8.3 and 1.9 are continuously tested.
Next, install the standard protocol buffer implementation from [https://github.com/google/protobuf](https://github.com/google/protobuf).
Most versions from 2.3.1 should not give any problems, but 2.6.1, 3.0.2 and 3.4.0 are continuously tested.
### Speed
Install the protoc-gen-gofast binary
go get github.com/gogo/protobuf/protoc-gen-gofast
Use it to generate faster marshaling and unmarshaling go code for your protocol buffers.
protoc --gofast_out=. myproto.proto
This does not allow you to use any of the other gogoprotobuf [extensions](https://github.com/gogo/protobuf/blob/master/extensions.md).
### More Speed and more generated code
Fields without pointers cause less time in the garbage collector.
More code generation results in more convenient methods.
Other binaries are also included:
protoc-gen-gogofast (same as gofast, but imports gogoprotobuf)
protoc-gen-gogofaster (same as gogofast, without XXX_unrecognized, less pointer fields)
protoc-gen-gogoslick (same as gogofaster, but with generated string, gostring and equal methods)
Installing any of these binaries is easy. Simply run:
go get github.com/gogo/protobuf/proto
go get github.com/gogo/protobuf/{binary}
go get github.com/gogo/protobuf/gogoproto
These binaries allow you to using gogoprotobuf [extensions](https://github.com/gogo/protobuf/blob/master/extensions.md).
### Most Speed and most customization
Customizing the fields of the messages to be the fields that you actually want to use removes the need to copy between the structs you use and structs you use to serialize.
gogoprotobuf also offers more serialization formats and generation of tests and even more methods.
Please visit the [extensions](https://github.com/gogo/protobuf/blob/master/extensions.md) page for more documentation.
Install protoc-gen-gogo:
go get github.com/gogo/protobuf/proto
go get github.com/gogo/protobuf/jsonpb
go get github.com/gogo/protobuf/protoc-gen-gogo
go get github.com/gogo/protobuf/gogoproto
## GRPC
It works the same as golang/protobuf, simply specify the plugin.
Here is an example using gofast:
protoc --gofast_out=plugins=grpc:. my.proto

# Custom types
Custom types is a gogo protobuf extensions that allows for using a custom
struct type to decorate the underlying structure of the protocol message.
# How to use
## Defining the protobuf message
```proto
message CustomType {
optional ProtoType Field = 1 [(gogoproto.customtype) = "T"];
}
message ProtoType {
optional string Field = 1;
}
```
or alternatively you can declare the field type in the protocol message to be
`bytes`:
```proto
message BytesCustomType {
optional bytes Field = 1 [(gogoproto.customtype) = "T"];
}
```
The downside of using `bytes` is that it makes it harder to generate protobuf
code in other languages. In either case, it is the user responsibility to
ensure that the custom type marshals and unmarshals to the expected wire
format. That is, in the first example, gogo protobuf will not attempt to ensure
that the wire format of `ProtoType` and `T` are wire compatible.
## Custom type method signatures
The custom type must define the following methods with the given
signatures. Assuming the custom type is called `T`:
```go
func (t T) Marshal() ([]byte, error) {}
func (t *T) MarshalTo(data []byte) (n int, err error) {}
func (t *T) Unmarshal(data []byte) error {}
func (t T) MarshalJSON() ([]byte, error) {}
func (t *T) UnmarshalJSON(data []byte) error {}
// only required if the compare option is set
func (t T) Compare(other T) int {}
// only required if the equal option is set
func (t T) Equal(other T) bool {}
// only required if populate option is set
func NewPopulatedT(r randyThetest) *T {}
```
Check [t.go](test/t.go) for a full example
# Warnings and issues
`Warning about customtype: It is your responsibility to test all cases of your marshaling, unmarshaling and size methods implemented for your custom type.`
Issues with customtype include:
* <a href="https://github.com/gogo/protobuf/issues/199">A Bytes method is not allowed.<a/>
* <a href="https://github.com/gogo/protobuf/issues/132">Defining a customtype as a fake proto message is broken.</a>

# gogoprotobuf Extensions
Here is an [example.proto](https://github.com/gogo/protobuf/blob/master/test/example/example.proto) which uses most of the gogoprotobuf code generation plugins.
Please also look at the example [Makefile](https://github.com/gogo/protobuf/blob/master/test/example/Makefile) which shows how to specify the `descriptor.proto` and `gogo.proto` in your proto_path
The documentation at [http://godoc.org/github.com/gogo/protobuf/gogoproto](http://godoc.org/github.com/gogo/protobuf/gogoproto) describes the extensions made to goprotobuf in more detail.
Also see [http://godoc.org/github.com/gogo/protobuf/plugin/](http://godoc.org/github.com/gogo/protobuf/plugin/) for documentation of each of the extensions which have their own plugins.
# Fast Marshalling and Unmarshalling
Generating a `Marshal`, `MarshalTo`, `Size` (or `ProtoSize`) and `Unmarshal` method for a struct results in faster marshalling and unmarshalling than when using reflect.
See [BenchComparison](https://github.com/gogo/protobuf/blob/master/bench.md) for a comparison between reflect and generated code used for marshalling and unmarshalling.

# More Canonical Go Structures
Lots of times 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 new struct.
`gogoprotobuf` tries to fix these problems with the nullable, embed, customtype, customname, casttype, castkey and castvalue field extensions.

`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.`
# Goprotobuf Compatibility
Gogoprotobuf is compatible with Goprotobuf, because it is compatible with protocol buffers (see the section on tests below).
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.

# Less Typing
The Protocol Buffer language is very parseable and extra code can be easily generated for structures.
Helper methods, functions and interfaces can be generated by triggering certain extensions like gostring.
<table>
<tr><td><b>Name</b></td><td><b>Option</b></td><td><b>Type</b></td><td><b>Description</b></td><td><b>Default</b></td></tr>
<tr><td><a href="http://godoc.org/github.com/gogo/protobuf/plugin/gostring">gostring</a></td><td> Message </td><td> bool </td><td> if true, a `GoString` method is generated. This returns a string representing valid go code to reproduce the current state of the struct. </td><td> false </td></tr>
<tr><td><a href="http://godoc.org/github.com/gogo/protobuf/plugin/union"> onlyone</a> (deprecated) </td><td> Message </td><td> bool </td><td> if true, all fields must be nullable and only one of the fields may be set, like a union. Two methods are generated: `GetValue() interface{}` and `SetValue(v interface{}) (set bool)`. These provide easier interaction with a union. </td><td> false </td></tr>

* <a href="https://github.com/gogo/protobuf/issues/230">Not all Well Known Types are supported yet</a>
* <a href="https://github.com/gogo/protobuf/issues/231">Maps are not supported</a>
#Peace of Mind
Test and Benchmark generation is done with the following extensions:
<table>
<tr><td><a href="http://godoc.org/github.com/gogo/protobuf/plugin/testgen">testgen</a> </td><td> Message </td><td> bool </td><td> if true, tests are generated for proto, json and prototext marshalling as well as for some of the other enabled plugins </td><td> false </td></tr>
<tr><td> benchgen </td><td> Message </td><td> bool </td><td> if true, benchmarks are generated for proto, json and prototext marshalling as well as for some of the other enabled plugins </td><td> false </td></tr>
</table>
# More Serialization Formats
Other serialization formats like xml and json typically use reflect to marshal and unmarshal structured data. Manipulating these structs into something other than the default Go requires editing tags. The following extensions provide ways of editing these tags for the generated protobuf structs.
<table>
<tr><td><a href="https://github.com/gogo/protobuf/blob/master/test/tags/tags.proto">jsontag</a> (beta) </td><td> Field </td><td> string </td><td> if set, the json tag value between the double quotes is replaced with this string </td><td> fieldname </td></tr>
<tr><td><a href="https://github.com/gogo/protobuf/blob/master/test/tags/tags.proto">moretags</a> (beta) </td><td> Field </td><td> string </td><td> if set, this string is appended to the tag string </td><td> empty </td></tr>
</table>
<a href="https://groups.google.com/forum/#!topic/gogoprotobuf/xmFnqAS6MIc">Here is a longer explanation of jsontag and moretags</a>
# File Options
Each of the boolean message and enum extensions also have a file extension:
* `marshaler_all`
* `sizer_all`
* `protosizer_all`
* `unmarshaler_all`
* `unsafe_marshaler_all`
* `unsafe_unmarshaler_all`
* `stable_marshaler_all`
* `goproto_enum_prefix_all`
* `goproto_getters_all`
* `goproto_stringer_all`
* `goproto_enum_stringer_all`
* `goproto_extensions_map_all`
* `goproto_unrecognized_all`
* `gostring_all`
* `onlyone_all`
* `equal_all`
* `compare_all`
* `verbose_equal_all`
* `stringer_all`
* `enum_stringer_all`
* `face_all`
* `description_all`
* `populate_all`
* `testgen_all`
* `benchgen_all`
* `enumdecl_all`
* `typedecl_all`
Each of these are the same as their Message Option counterparts, except they apply to all messages in the file. Their Message option counterparts can also be used to overwrite their effect.
# Tests
* The normal barrage of tests are run with: `make tests`
* A few weird tests: `make testall`
* Tests for compatibility with [golang/protobuf](https://github.com/golang/protobuf) are handled by a different project [harmonytests](https://github.com/gogo/harmonytests), since it requires goprotobuf.
* Cross version tests are made with [Travis CI](https://travis-ci.org/gogo/protobuf).
* GRPC Tests are also handled by a different project [grpctests](https://github.com/gogo/grpctests), since it depends on a lot of grpc libraries.
* Thanks to [go-fuzz](https://github.com/dvyukov/go-fuzz/) we have proper [fuzztests](https://github.com/gogo/fuzztests).

/*
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 independant 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;

you can run
protoc --gogo_out=output_directory input_directory/file.proto

glog
====
Leveled execution logs for Go.
This is an efficient pure Go implementation of leveled logs in the
manner of the open source C++ package
https://github.com/google/glog
By binding methods to booleans it is possible to use the log package
without paying the expense of evaluating the arguments to the log.
Through the -vmodule flag, the package also provides fine-grained
control over logging at the file level.
The comment from glog.go introduces the ideas:
Package glog implements logging analogous to the Google-internal
C++ INFO/ERROR/V setup. It provides functions Info, Warning,
Error, Fatal, plus formatting variants such as Infof. It
also provides V-style logging controlled by the -v and
-vmodule=file=2 flags.
Basic examples:
glog.Info("Prepare to repel boarders")
glog.Fatalf("Initialization failed: %s", err)
See the documentation for the V function for an explanation
of these examples:
if glog.V(2) {
glog.Info("Starting transaction...")
}
glog.V(2).Infoln("Processed", nItems, "elements")
The repository contains an open source version of the log package
used inside Google. The master copy of the source lives inside
Google, not here. The code in this repo is for export only and is not itself
under development. Feature requests will be ignored.
