+# *EXPERIMENTAL* Go binding for proton
+
+This is the beginning of a [Go](http://golang.org) binding for proton.
+
+This work is in early *experimental* stages, *everything* may change in future.
+Comments and contributions are strongly encouraged, this experiment is public so
+early feedback can guide development.
+
+- Email <proton@qpid.apache.org>
+- Create issues <https://issues.apache.org/jira/browse/PROTON>, attach patches to an issue.
+
+There are working [examples](../examples/go/README.md)
+
+## Goals
+
+The API should
+
+- be idiomatic, unsurprising, and easy to use for Go developers.
+- support client and server development.
+- make simple tasks simple.
+- provide deep access to AMQP protocol when that is required.
+
+There are two types of developer we want to support
+
+1. Go developers using AMQP as a message transport:
+   - Straightforward conversions between Go built-in types and AMQP types.
+   - Easy message exchange via Go channels to support use in goroutines.
+
+2. AMQP-aware developers using Go as an implementation language:
+   - Go types to exactly represent all AMQP types and encoding details.
+   - Full access to detailed AMQP concepts: sessions, links, deliveries etc.
+
+## Status
+
+There are 3 go packages for proton:
+
+- qpid.apache.org/proton/go/amqp: converts AMQP messages and data types to and from Go data types.
+- qpid.apache.org/proton/go/messaging: easy-to-use, concurrent API for messaging clients and servers.
+- qpid.apache.org/proton/go/event: full low-level access to the proton engine.
+
+Most applications should use the `messaging` package. The `event` package is for
+applications that need low-level access to the proton engine.
+
+The `event` package is fairly complete, with the exception of the proton
+reactor. It's unclear if the reactor is important for go.
+
+The `messaging` package can run the examples but probably not much else. There
+is work to do on error handling and the API may change.
+
+There are working [examples](../../../examples/go/README.md) of a broker using `event` and
+a sender and receiver using `messaging`.
+
+## The event driven API
+
+See the package documentation for details.
+
+## The Go API
+
+The goal: A procedural API that allows any user goroutine to send and receive
+AMQP messages and other information (acknowledgments, flow control instructions
+etc.) using channels. There will be no user-visible locks and no need to run
+user code in special goroutines, e.g. as handlers in a proton event loop.
+
+See the package documentation for emerging details.
+
+Currently using a channel to receive messages, a function to send them (channels
+internally) and a channel as a "future" for acknowledgements to senders. This
+may change.
+
+## Why a separate API for Go?
+
+Go is a concurrent language and encourages applications to be divided into
+concurrent *goroutines*. It provides traditional locking but it encourages the
+use *channels* to communicate between goroutines without explicit locks:
+
+  "Share memory by communicating, don't communicate by sharing memory"
+
+The idea is that a given value is only operated on by one goroutine at a time,
+but values can easily be passed from one goroutine to another. This removes much
+of the need for locking.
+
+Go literature distinguishes between:
+
+- *concurrency*: "keeping track of things that could be done in parallel"
+- *parallelism*: "actually doing things in parallel"
+
+The application expresses concurrency by starting goroutines for potentially
+concurrent tasks. The Go run-times schedule the activity of goroutines onto a
+small number (possibly one) of actual parallel executions.
+
+Even with *no* parallelism, concurrency lets the Go run-times *order* work with
+respect to events like file descriptors being readable/writable, channels having
+data, timers firing etc. Go automatically takes care of switching out goroutines
+that block or sleep so it is normal to write code in terms of blocking calls.
+
+Event-driven API (like poll, epoll, select or the proton event API) also
+channel unpredictably ordered events to actions in one or a small pool of
+execution threads. However this requires a different style of programming:
+"event-driven" or "reactive" programming. Go developers call it "inside-out"
+programming. In an event-driven architecture blocking is a big problem as it
+consumes a scarce thread of execution, so actions that take time to complete
+have to be re-structured in terms of future event delivery.
+
+The promise of Go is that you can express your application in concurrent,
+procedural terms with simple blocking calls and the Go run-times will turn it
+inside-out for you. Write as many goroutines as you want, and let Go interleave
+and schedule them efficiently.
+
+For example: the Go equivalent of listening for connections is a goroutine with
+a simple endless loop that calls a blocking Listen() function and starts a
+goroutine for each new connection. Each connection has its own goroutine that
+deals with just that connection till it closes.
+
+The benefit is that the variables and logic live closer together. Once you're in
+a goroutine, you have everything you need in local variables, and they are
+preserved across blocking calls. There's no need to store details in context
+objects that you have to look up when handling a later event to figure out how
+to continue where you left off.
+
+So a Go-like proton API does not force the users code to run in an event-loop
+goroutine. Instead user goroutines communicate with the event loop(s) via
+channels.  There's no need to funnel connections into one event loop, in fact it
+makes no sense.  Connections can be processed concurrently so they should be
+processed in separate goroutines and left to Go to schedule. User goroutines can
+have simple loops that block channels till messages are available, the user can
+start as many or as few such goroutines as they wish to implement concurrency as
+simple or as complex as they wish. For example blocking request-response
+vs. asynchronous flows of messages and acknowledgments.
+
+## New to Go?
+
+If you are new to Go then these are a good place to start:
+
+- [A Tour of Go](http://tour.golang.org)
+- [Effective Go](http://golang.org/doc/effective_go.html)
+
+Then look at the tools and library docs at <http://golang.org> as you need them.

+Package amqp encodes and decodes AMQP messages and data as Go types.
+
+It follows the standard 'encoding' libraries pattern. The mapping between AMQP
+and Go types is described in the documentation of the Marshal and Unmarshal
+functions.
+
+The sub-packages 'event' and 'messaging' provide two alternative ways to write
+AMQP clients and servers. 'messaging' is easier for general purpose use. 'event'
+gives complete low-level control of the underlying proton C engine.
+
+AMQP is an open standard for inter-operable message exchange, see <http://www.amqp.org/>
