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. + +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

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. + - Getters are only generated for message and oneof fields. + - 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;

You can have as many queue groups as you wish. + +Normal subscribers will continue to work as expected. + +#### Creating a Queue Group + +A queue group is automatically created when the first queue subscriber is +created. If the group already exists, the member is added to the group. + +```go +sc, _ := stan.Connect("test-cluster", "clientid") + +// Create a queue subscriber on "foo" for group "bar" +qsub1, _ := sc.QueueSubscribe("foo", "bar", qcb) + +// Add a second member +qsub2, _ := sc.QueueSubscribe("foo", "bar", qcb) + +// Notice that you can have a regular subscriber on that subject +sub, _ := sc.Subscribe("foo", cb) + +// A message on "foo" will be received by sub and qsub1 or qsub2. +``` + +#### Start Position + +Note that once a queue group is formed, a member's start position is ignored +when added to the group. It will start receive messages from the last +position in the group. + +Suppose the channel `foo` exists and there are `500` messages stored, the group +`bar` is already created, there are two members and the last +message sequence sent is `100`. A new member is added. Note its start position: + +```go +sc.QueueSubscribe("foo", "bar", qcb, stan.StartAtSequence(200)) +``` + +This will not produce an error, but the start position will be ignored. Assuming +this member would be the one receiving the next message, it would receive message +sequence `101`. + +#### Leaving the Group + +There are two ways of leaving the group: closing the subscriber's connection or +calling `Unsubscribe`: + +```go +// Have qsub leave the queue group +qsub.Unsubscribe() +``` + +If the leaving member had un-acknowledged messages, those messages are reassigned +to the remaining members. + +#### Closing a Queue Group + +There is no special API for that. Once all members have left (either calling `Unsubscribe`, +or their connections are closed), the group is removed from the server. + +The next call to `QueueSubscribe` with the same group name will create a brand new group, +that is, the start position will take effect and delivery will start from there. + +### Durable Queue Groups + +As described above, for non durable queue subsribers, when the last member leaves the group, +that group is removed. A durable queue group allows you to have all members leave but still +maintain state. When a member re-joins, it starts at the last position in that group. + +#### Creating a Durable Queue Group + +A durable queue group is created in a similar manner as that of a standard queue group, +except the `DurableName` option must be used to specify durability. + +```go +sc.QueueSubscribe("foo", "bar", qcb, stan.DurableName("dur")) +``` +A group called `dur:bar` (the concatenation of durable name and group name) is created in +the server. This means two things: + +- The character `:` is not allowed for a queue subscriber's durable name. +- Durable and non-durable queue groups with the same name can coexist. + +```go +// Non durable queue subscriber on group "bar" +qsub, _ := sc.QueueSubscribe("foo", "bar", qcb) + +// Durable queue subscriber on group "bar" +durQsub, _ := sc.QueueSubscribe("foo", "bar", qcb, stan.DurableName("mydurablegroup")) + +// The same message produced on "foo" would be received by both queue subscribers. +``` + +#### Start Position + +The rules for non-durable queue subscribers apply to durable subscribers. + +#### Leaving the Group + +As for non-durable queue subscribers, if a member's connection is closed, or if +`Unsubscribe` its called, the member leaves the group. Any unacknowledged message +is transfered to remaining members. See *Closing the Group* for important difference +with non-durable queue subscribers. + +#### Closing the Group + +The *last* member calling `Unsubscribe` will close (that is destroy) the +group. So if you want to maintain durability of the group, you should not be +calling `Unsubscribe`. + +So unlike for non-durable queue subscribers, it is possible to maintain a queue group +with no member in the server. When a new member re-joins the durable queue group, +it will resume from where the group left of, actually first receiving all unacknowledged +messages that may have been left when the last member previously left. + + +### Wildcard Subscriptions + +NATS Streaming subscriptions **do not** support wildcards. + + +## Advanced Usage + +### Asynchronous Publishing + +The basic publish API (`Publish(subject, payload)`) is synchronous; it does not return control to the caller until the NATS Streaming server has acknowledged receipt of the message. To accomplish this, a [NUID](https://github.com/nats-io/nuid) is generated for the message on creation, and the client library waits for a publish acknowledgement from the server with a matching NUID before it returns control to the caller, possibly with an error indicating that the operation was not successful due to some server problem or authorization error. + +Advanced users may wish to process these publish acknowledgements manually to achieve higher publish throughput by not waiting on individual acknowledgements during the publish operation. An asynchronous publish API is provided for this purpose: + +```go + ackHandler := func(ackedNuid string, err error) { + if err != nil { + log.Printf("Warning: error publishing msg id %s: %v\n", ackedNuid, err.Error()) + } else { + log.Printf("Received ack for msg id %s\n", ackedNuid) + } + } + + // can also use PublishAsyncWithReply(subj, replysubj, payload, ah) + nuid, err := sc.PublishAsync("foo", []byte("Hello World"), ackHandler) // returns immediately + if err != nil { + log.Printf("Error publishing msg %s: %v\n", nuid, err.Error()) + } +``` + +### Message Acknowledgements and Redelivery + +NATS Streaming offers At-Least-Once delivery semantics, meaning that once a message has been delivered to an eligible subscriber, if an acknowledgement is not received within the configured timeout interval, NATS Streaming will attempt redelivery of the message. +This timeout interval is specified by the subscription option `AckWait`, which defaults to 30 seconds. + +By default, messages are automatically acknowledged by the NATS Streaming client library after the subscriber's message handler is invoked. However, there may be cases in which the subscribing client wishes to accelerate or defer acknowledgement of the message. +To do this, the client must set manual acknowledgement mode on the subscription, and invoke `Ack()` on the `Msg`. ex: + +```go +// Subscribe with manual ack mode, and set AckWait to 60 seconds +aw, _ := time.ParseDuration("60s") +sub, err := sc.Subscribe("foo", func(m *stan.Msg) { + m.Ack() // ack message before performing I/O intensive operation + ///... + fmt.Printf("Received a message: %s\n", string(m.Data)) +}, stan.SetManualAckMode(), stan.AckWait(aw)) +``` + +## Rate limiting/matching + +A classic problem of publish-subscribe messaging is matching the rate of message producers with the rate of message consumers. +Message producers can often outpace the speed of the subscribers that are consuming their messages. +This mismatch is commonly called a "fast producer/slow consumer" problem, and may result in dramatic resource utilization spikes in the underlying messaging system as it tries to buffer messages until the slow consumer(s) can catch up. + +### Publisher rate limiting + +NATS Streaming provides a connection option called `MaxPubAcksInflight` that effectively limits the number of unacknowledged messages that a publisher may have in-flight at any given time. When this maximum is reached, further `PublishAsync()` calls will block until the number of unacknowledged messages falls below the specified limit. ex: + +```go +sc, _ := stan.Connect(clusterID, clientID, MaxPubAcksInflight(25)) + +ah := func(nuid string, err error) { + // process the ack + ... +} + +for i := 1; i < 1000; i++ { + // If the server is unable to keep up with the publisher, the number of oustanding acks will eventually + // reach the max and this call will block + guid, _ := sc.PublishAsync("foo", []byte("Hello World"), ah) +} +``` + +### Subscriber rate limiting + +Rate limiting may also be accomplished on the subscriber side, on a per-subscription basis, using a subscription option called `MaxInflight`. +This option specifies the maximum number of outstanding acknowledgements (messages that have been delivered but not acknowledged) that NATS Streaming will allow for a given subscription. +When this limit is reached, NATS Streaming will suspend delivery of messages to this subscription until the number of unacknowledged messages falls below the specified limit. ex: + +```go +// Subscribe with manual ack mode and a max in-flight limit of 25 +sc.Subscribe("foo", func(m *stan.Msg) { + fmt.Printf("Received message #: %s\n", string(m.Data)) + ... + // Does not ack, or takes a very long time to ack + ... + // Message delivery will suspend when the number of unacknowledged messages reaches 25 +}, stan.SetManualAckMode(), stan.MaxInflight(25)) + +``` + +## License + +(The MIT License) + +Copyright (c) 2012-2016 Apcera Inc. + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to +deal in the Software without restriction, including without limitation the +rights to use, copy, modify, merge, publish, distribute, sublicense, and/or +sell copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in +all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
