+Suture
+======
+
+[![Build Status](https://travis-ci.org/thejerf/suture.png?branch=master)](https://travis-ci.org/thejerf/suture)
+
+Suture provides Erlang-ish supervisor trees for Go. "Supervisor trees" ->
+"sutree" -> "suture" -> holds your code together when it's trying to die.
+
+This is intended to be a production-quality library going into code that I
+will be very early on the phone tree to support when it goes down. However,
+it has not been deployed into something quite that serious yet. (I will
+update this statement when that changes.)
+
+It is intended to deal gracefully with the real failure cases that can
+occur with supervision trees (such as burning all your CPU time endlessly
+restarting dead services), while also making no unnecessary demands on the
+"service" code, and providing hooks to perform adequate logging with in a
+production environment.
+
+[A blog post describing the design decisions](http://www.jerf.org/iri/post/2930)
+is available.
+
+This module is fully covered with [godoc](http://godoc.org/github.com/thejerf/suture),
+including an example, usage, and everything else you might expect from a
+README.md on GitHub. (DRY.)
+
+This is not currently tagged with particular git tags for Go as this is
+currently considered to be alpha code. As I move this into production and
+feel more confident about it, I'll give it relevant tags.
+
+Code Signing
+------------
+
+Starting with the commit after ac7cf8591b, I will be signing this repository
+with the ["jerf" keybase account](https://keybase.io/jerf).
+
+Aspiration
+----------
+
+One of the big wins the Erlang community has with their pervasive OTP
+support is that it makes it easy for them to distribute libraries that
+easily fit into the OTP paradigm. It ought to someday be considered a good
+idea to distribute libraries that provide some sort of supervisor tree
+functionality out of the box. It is possible to provide this functionality
+without explicitly depending on the Suture library.

+
+Package suture provides Erlang-like supervisor trees.
+
+This implements Erlang-esque supervisor trees, as adapted for Go. This is
+intended to be an industrial-strength implementation, but it has not yet
+been deployed in a hostile environment. (It's headed there, though.)
+
+Supervisor Tree -> SuTree -> suture -> holds your code together when it's
+trying to fall apart.
+
+Why use Suture?
+
+ * You want to write bullet-resistant services that will remain available
+   despite unforeseen failure.
+ * You need the code to be smart enough not to consume 100% of the CPU
+   restarting things.
+ * You want to easily compose multiple such services in one program.
+ * You want the Erlang programmers to stop lording their supervision
+   trees over you.
+
+Suture has 100% test coverage, and is golint clean. This doesn't prove it
+free of bugs, but it shows I care.
+
+A blog post describing the design decisions is available at
+http://www.jerf.org/iri/post/2930 .
+
+Using Suture
+
+To idiomatically use Suture, create a Supervisor which is your top level
+"application" supervisor. This will often occur in your program's "main"
+function.
+
+Create "Service"s, which implement the Service interface. .Add() them
+to your Supervisor. Supervisors are also services, so you can create a
+tree structure here, depending on the exact combination of restarts
+you want to create.
+
+Finally, as what is probably the last line of your main() function, call
+.Serve() on your top level supervisor. This will start all the services
+you've defined.
+
+See the Example for an example, using a simple service that serves out
+incrementing integers.

+Once constructed, a Supervisor should be started in one of three ways:
+
+ 1. Calling .Serve().
+ 2. Calling .ServeBackground().
+ 3. Adding it to an existing Supervisor.
+
+Calling Serve will cause the supervisor to run until it is shut down by
+an external user calling Stop() on it. If that never happens, it simply
+runs forever. I suggest creating your services in Supervisors, then making
+a Serve() call on your top-level Supervisor be the last line of your main
+func.
+
+Calling ServeBackground will CORRECTLY start the supervisor running in a
+new goroutine. You do not want to just:
+
+  go supervisor.Serve()
+
+because that will briefly create a race condition as it starts up, if you
+try to .Add() services immediately afterward.

+New is the full constructor function for a supervisor.
+
+The name is a friendly human name for the supervisor, used in logging. Suture
+does not care if this is unique, but it is good for your sanity if it is.

+If not set, the following values are used:
+
+ * Log:               A function is created that uses log.Print.
+ * FailureDecay:      30 seconds
+ * FailureThreshold:  5 failures
+ * FailureBackoff:    15 seconds
+ * Timeout:           10 seconds
+
+The Log function will be called when errors occur. Suture will log the
+following:
+
+ * When a service has failed, with a descriptive message about the
+   current backoff status, and whether it was immediately restarted
+ * When the supervisor has gone into its backoff mode, and when it
+   exits it
+ * When a service fails to stop
+
+The failureRate, failureThreshold, and failureBackoff controls how failures
+are handled, in order to avoid the supervisor failure case where the
+program does nothing but restarting failed services. If you do not
+care how failures behave, the default values should be fine for the
+vast majority of services, but if you want the details:
+
+The supervisor tracks the number of failures that have occurred, with an
+exponential decay on the count. Every FailureDecay seconds, the number of
+failures that have occurred is cut in half. (This is done smoothly with an
+exponential function.) When a failure occurs, the number of failures
+is incremented by one. When the number of failures passes the
+FailureThreshold, the entire service waits for FailureBackoff seconds
+before attempting any further restarts, at which point it resets its
+failure count to zero.
+
+Timeout is how long Suture will wait for a service to properly terminate.

+Service is the interface that describes a service to a Supervisor.
+
+Serve Method
+
+The Serve method is called by a Supervisor to start the service.
+The service should execute within the goroutine that this is
+called in. If this function either returns or panics, the Supervisor
+will call it again.
+
+A Serve method SHOULD do as much cleanup of the state as possible,
+to prevent any corruption in the previous state from crashing the
+service again.
+
+Stop Method
+
+This method is used by the supervisor to stop the service. Calling this
+directly on a Service given to a Supervisor will simply result in the
+Service being restarted; use the Supervisor's .Remove(ServiceToken) method
+to stop a service. A supervisor will call .Stop() only once. Thus, it may
+be as destructive as it likes to get the service to stop.
+
+Once Stop has been called on a Service, the Service SHOULD NOT be
+reused in any other supervisor! Because of the impossibility of
+guaranteeing that the service has actually stopped in Go, you can't
+prove that you won't be starting two goroutines using the exact
+same memory to store state, causing completely unpredictable behavior.
+
+Stop should not return until the service has actually stopped.
+"Stopped" here is defined as "the service will stop servicing any
+further requests in the future". For instance, a common implementation
+is to receive a message on a dedicated "stop" channel and immediately
+returning. Once the stop command has been processed, the service is
+stopped.
+
+Another common Stop implementation is to forcibly close an open socket
+or other resource, which will cause detectable errors to manifest in the
+service code. Bear in mind that to perfectly correctly use this
+approach requires a bit more work to handle the chance of a Stop
+command coming in before the resource has been created.
+
+If a service does not Stop within the supervisor's timeout duration, a log
+entry will be made with a descriptive string to that effect. This does
+not guarantee that the service is hung; it may still get around to being
+properly stopped in the future. Until the service is fully stopped,
+both the service and the spawned goroutine trying to stop it will be
+"leaked".
+
+Stringer Interface
+
+It is not mandatory to implement the fmt.Stringer interface on your
+service, but if your Service does happen to implement that, the log
+messages that describe your service will use that when naming the
+service. Otherwise, you'll see the GoString of your service object,
+obtained via fmt.Sprintf("%#v", service).
