# AMQP
|
||||||
|
|
||||||
|
AMQP 0.9.1 client with RabbitMQ extensions in Go.
|
||||||
|
|
||||||
|
# Status
|
||||||
|
|
||||||
|
*Beta*
|
||||||
|
|
||||||
|
[![Build Status](https://secure.travis-ci.org/streadway/amqp.png)](http://travis-ci.org/streadway/amqp)
|
||||||
|
|
||||||
|
API changes unlikely and will be discussed on [Github
|
||||||
|
issues](https://github.com/streadway/amqp/issues) along with any bugs or
|
||||||
|
enhancements.
|
||||||
|
|
||||||
|
# Goals
|
||||||
|
|
||||||
|
Provide an functional interface that closely represents the AMQP 0.9.1 model
|
||||||
|
targeted to RabbitMQ as a server. This includes the minimum necessary to
|
||||||
|
interact the semantics of the protocol.
|
||||||
|
|
||||||
|
# Non-goals
|
||||||
|
|
||||||
|
Things not intended to be supported.
|
||||||
|
|
||||||
|
* Auto reconnect and re-synchronization of client and server topologies.
|
||||||
|
* Reconnection would require understanding the error paths when the
|
||||||
|
topology cannot be declared on reconnect. This would require a new set
|
||||||
|
of types and code paths that are best suited at the call-site of this
|
||||||
|
package. AMQP has a dynamic topology that needs all peers to agree. If
|
||||||
|
this doesn't happen, the behavior is undefined. Instead of producing a
|
||||||
|
possible interface with undefined behavior, this package is designed to
|
||||||
|
be simple for the caller to implement the necessary connection-time
|
||||||
|
topology declaration so that reconnection is trivial and encapsulated in
|
||||||
|
the caller's application code.
|
||||||
|
* AMQP Protocol negotiation for forward or backward compatibility.
|
||||||
|
* 0.9.1 is stable and widely deployed. Versions 0.10 and 1.0 are divergent
|
||||||
|
specifications that change the semantics and wire format of the protocol.
|
||||||
|
We will accept patches for other protocol support but have no plans for
|
||||||
|
implementation ourselves.
|
||||||
|
* Anything other than PLAIN and EXTERNAL authentication mechanisms.
|
||||||
|
* Keeping the mechanisms interface modular makes it possible to extend
|
||||||
|
outside of this package. If other mechanisms prove to be popular, then
|
||||||
|
we would accept patches to include them in this pacakge.
|
||||||
|
|
||||||
|
# Usage
|
||||||
|
|
||||||
|
See the 'examples' subdirectory for simple producers and consumers executables.
|
||||||
|
If you have a use-case in mind which isn't well-represented by the examples,
|
||||||
|
please file an issue.
|
||||||
|
|
||||||
|
# Documentation
|
||||||
|
|
||||||
|
Use [Godoc documentation](http://godoc.org/github.com/streadway/amqp) for
|
||||||
|
reference and usage.
|
||||||
|
|
||||||
|
[RabbitMQ tutorials in
|
||||||
|
Go](https://github.com/rabbitmq/rabbitmq-tutorials/tree/master/go) are also
|
||||||
|
available.
|
||||||
|
|
||||||
|
# Contributing
|
||||||
|
|
||||||
|
Pull requests are very much welcomed. Create your pull request on a non-master
|
||||||
|
branch, make sure a test or example is included that covers your change and
|
||||||
|
your commits represent coherent changes that include a reason for the change.
|
||||||
|
|
||||||
|
To run the integration tests, make sure you have RabbitMQ running on any host,
|
||||||
|
export the environment variable `AMQP_URL=amqp://host/` and run `go test -tags
|
||||||
|
integration`. TravisCI will also run the integration tests.

AMQP 0.9.1 client with RabbitMQ extensions
|
||||||
|
|
||||||
|
Understand the AMQP 0.9.1 messaging model by reviewing these links first. Much
|
||||||
|
of the terminology in this library directly relates to AMQP concepts.
|
||||||
|
|
||||||
|
Resources
|
||||||
|
|
||||||
|
http://www.rabbitmq.com/tutorials/amqp-concepts.html
|
||||||
|
http://www.rabbitmq.com/getstarted.html
|
||||||
|
http://www.rabbitmq.com/amqp-0-9-1-reference.html
|
||||||
|
|
||||||
|
Design
|
||||||
|
|
||||||
|
Most other broker clients publish to queues, but in AMQP, clients publish
|
||||||
|
Exchanges instead. AMQP is programmable, meaning that both the producers and
|
||||||
|
consumers agree on the configuration of the broker, instead requiring an
|
||||||
|
operator or system configuration that declares the logical topology in the
|
||||||
|
broker. The routing between producers and consumer queues is via Bindings.
|
||||||
|
These bindings form the logical topology of the broker.
|
||||||
|
|
||||||
|
In this library, a message sent from publisher is called a "Publishing" and a
|
||||||
|
message received to a consumer is called a "Delivery". The fields of
|
||||||
|
Publishings and Deliveries are close but not exact mappings to the underlying
|
||||||
|
wire format to maintain stronger types. Many other libraries will combine
|
||||||
|
message properties with message headers. In this library, the message well
|
||||||
|
known properties are strongly typed fields on the Publishings and Deliveries,
|
||||||
|
whereas the user defined headers are in the Headers field.
|
||||||
|
|
||||||
|
The method naming closely matches the protocol's method name with positional
|
||||||
|
parameters mapping to named protocol message fields. The motivation here is to
|
||||||
|
present a comprehensive view over all possible interactions with the server.
|
||||||
|
|
||||||
|
Generally, methods that map to protocol methods of the "basic" class will be
|
||||||
|
elided in this interface, and "select" methods of various channel mode selectors
|
||||||
|
will be elided for example Channel.Confirm and Channel.Tx.
|
||||||
|
|
||||||
|
The library is intentionally designed to be synchronous, where responses for
|
||||||
|
each protocol message are required to be received in an RPC manner. Some
|
||||||
|
methods have a noWait parameter like Channel.QueueDeclare, and some methods are
|
||||||
|
asynchronous like Channel.Publish. The error values should still be checked for
|
||||||
|
these methods as they will indicate IO failures like when the underlying
|
||||||
|
connection closes.
|
||||||
|
|
||||||
|
Asynchronous Events
|
||||||
|
|
||||||
|
Clients of this library may be interested in receiving some of the protocol
|
||||||
|
messages other than Deliveries like basic.ack methods while a channel is in
|
||||||
|
confirm mode.
|
||||||
|
|
||||||
|
The Notify* methods with Connection and Channel receivers model the pattern of
|
||||||
|
asynchronous events like closes due to exceptions, or messages that are sent out
|
||||||
|
of band from an RPC call like basic.ack or basic.flow.
|
||||||
|
|
||||||
|
Any asynchronous events, including Deliveries and Publishings must always have
|
||||||
|
a receiver until the corresponding chans are closed. Without asynchronous
|
||||||
|
receivers, the sychronous methods will block.
|
||||||
|
|
||||||
|
Use Case
|
||||||
|
|
||||||
|
It's important as a client to an AMQP topology to ensure the state of the
|
||||||
|
broker matches your expectations. For both publish and consume use cases,
|
||||||
|
make sure you declare the queues, exchanges and bindings you expect to exist
|
||||||
|
prior to calling Channel.Publish or Channel.Consume.
|
||||||
|
|
||||||
|
// Connections start with amqp.Dial() typically from a command line argument
|
||||||
|
// or environment variable.
|
||||||
|
connection, err := amqp.Dial(os.Getenv("AMQP_URL"))
|
||||||
|
|
||||||
|
// To cleanly shutdown by flushing kernel buffers, make sure to close and
|
||||||
|
// wait for the response.
|
||||||
|
defer connection.Close()
|
||||||
|
|
||||||
|
// Most operations happen on a channel. If any error is returned on a
|
||||||
|
// channel, the channel will no longer be valid, throw it away and try with
|
||||||
|
// a different channel. If you use many channels, it's useful for the
|
||||||
|
// server to
|
||||||
|
channel, err := connection.Channel()
|
||||||
|
|
||||||
|
// Declare your topology here, if it doesn't exist, it will be created, if
|
||||||
|
// it existed already and is not what you expect, then that's considered an
|
||||||
|
// error.
|
||||||
|
|
||||||
|
// Use your connection on this topology with either Publish or Consume, or
|
||||||
|
// inspect your queues with QueueInspect. It's unwise to mix Publish and
|
||||||
|
// Consume to let TCP do its job well.
|
||||||
|
|
||||||
|
SSL/TLS - Secure connections
|
||||||
|
|
||||||
|
When Dial encounters an amqps:// scheme, it will use the zero value of a
|
||||||
|
tls.Config. This will only perform server certificate and host verification.
|
||||||
|
|
||||||
|
Use DialTLS when you wish to provide a client certificate (recommended),
|
||||||
|
include a private certificate authority's certificate in the cert chain for
|
||||||
|
server validity, or run insecure by not verifying the server certificate dial
|
||||||
|
your own connection. DialTLS will use the provided tls.Config when it
|
||||||
|
encounters an amqps:// scheme and will dial a plain connection when it
|
||||||
|
encounters an amqp:// scheme.
|
||||||
|
|
||||||
|
SSL/TLS in RabbitMQ is documented here: http://www.rabbitmq.com/ssl.html

Reads a frame from an input stream and returns an interface that can be cast into

2.3.5 frame Details
|
||||||
|
|
||||||
|
All frames consist of a header (7 octets), a payload of arbitrary size, and a
|
||||||
|
'frame-end' octet that detects malformed frames:
|
||||||
|
|
||||||
|
0 1 3 7 size+7 size+8
|
||||||
|
+------+---------+-------------+ +------------+ +-----------+
|
||||||
|
| type | channel | size | | payload | | frame-end |
|
||||||
|
+------+---------+-------------+ +------------+ +-----------+
|
||||||
|
octet short long size octets octet
|
||||||
|
|
||||||
|
To read a frame, we:
|
||||||
|
1. Read the header and check the frame type and channel.
|
||||||
|
2. Depending on the frame type, we read the payload and process it.
|
||||||
|
3. Read the frame end octet.
|
||||||
|
|
||||||
|
In realistic implementations where performance is a concern, we would use
|
||||||
|
“read-ahead buffering” or
|
||||||
|
|
||||||
|
“gathering reads” to avoid doing three separate system calls to read a frame.

2.3.5 frame Details
|
||||||
|
|
||||||
|
All frames consist of a header (7 octets), a payload of arbitrary size, and a 'frame-end' octet that detects
|
||||||
|
malformed frames:
|
||||||
|
|
||||||
|
0 1 3 7 size+7 size+8

+------+---------+-------------+ +------------+ +-----------+
|
||||||
|
octet short long size octets octet
|
||||||
|
|
||||||
|
To read a frame, we:
|
||||||
|
|
||||||
|
1. Read the header and check the frame type and channel.
|
||||||
|
2. Depending on the frame type, we read the payload and process it.
|
||||||
|
3. Read the frame end octet.
|
||||||
|
|
||||||
|
In realistic implementations where performance is a concern, we would use
|
||||||
|
“read-ahead buffering” or “gathering reads” to avoid doing three separate
|
||||||
|
system calls to read a frame.

Method frames carry the high-level protocol commands (which we call "methods").

One method frame carries one command. The method frame payload has this format:

|

|
0 2 4

To process a method frame, we:

1. Read the method frame payload.
|
||||||
|
2. Unpack it into a structure. A given method always has the same structure,
|
||||||
|
so we can unpack the method rapidly. 3. Check that the method is allowed in
|
||||||
|
the current context.
|
||||||
|
4. Check that the method arguments are valid.
|
||||||
|
5. Execute the method.
|
||||||
|
|
||||||
|
Method frame bodies are constructed as a list of AMQP data fields (bits,
|
||||||
|
integers, strings and string tables). The marshalling code is trivially
|
||||||
|
generated directly from the protocol specifications, and can be very rapid.
