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/ + +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. + +*/ +package gogoproto diff --git a/vendor/github.com/gogo/protobuf/gogoproto/gogo.pb.go b/vendor/github.com/gogo/protobuf/gogoproto/gogo.pb.go new file mode 100644 index 0000000000..97843b2448 --- /dev/null +++ b/vendor/github.com/gogo/protobuf/gogoproto/gogo.pb.go @@ -0,0 +1,817 @@ +// Code generated by protoc-gen-gogo.

The error model is designed to be: +// +// - Simple to use and understand for most users +// - Flexible enough to meet unexpected needs +// +// # Overview +// +// The `Status` message contains three pieces of data: error code, error message, +// and error details. The error code should be an enum value of +// [google.rpc.Code][google.rpc.Code], but it may accept additional error codes if needed. The +// error message should be a developer-facing English message that helps +// developers *understand* and *resolve* the error. If a localized user-facing +// error message is needed, put the localized message in the error details or +// localize it in the client. The optional error details may contain arbitrary +// information about the error. There is a predefined set of error detail types +// in the package `google.rpc` that can be used for common error conditions. +// +// # Language mapping +// +// The `Status` message is the logical representation of the error model, but it +// is not necessarily the actual wire format. When the `Status` message is +// exposed in different client libraries and different wire protocols, it can be +// mapped differently. For example, it will likely be mapped to some exceptions +// in Java, but more likely mapped to some error codes in C. +// +// # Other uses +// +// The error model and the `Status` message can be used in a variety of +// environments, either with or without APIs, to provide a +// consistent developer experience across different environments. +// +// Example uses of this error model include: +// +// - Partial errors. If a service needs to return partial errors to the client, +// it may embed the `Status` in the normal response to indicate the partial +// errors. +// +// - Workflow errors.

A template is used for the default values that can be changed with a CR. When the CR is deleted, the values are reverted back to its defaults. The following options can be configured in /etc/crio/crio.conf - pidsLimit - logLevel - logSizeMax - infraImage The following options can be configured in /etc/containers/storage.conf: - overlaySize
