Subject: [PATCH 008/538] optimize partial message scheduling

- split only right before send (if necessary)
- do not reschedule Tick if that has already been done, because the head
  of the queue does not change so the old data are still correct
- make test a bit less fickle wrt. timing

 Overview
 ========
 
-Akka supports a set of durable mailboxes. A durable mailbox is a replacement for
-the standard actor mailbox that is durable. What this means in practice is that
-if there are pending messages in the actor's mailbox when the node of the actor
-resides on crashes, then when you restart the node, the actor will be able to
-continue processing as if nothing had happened; with all pending messages still
-in its mailbox.

+One basic file based durable mailbox is provided by Akka out-of-the-box.
+Other implementations can easily be added. Some are available as separate community
+Open Source projects, such as:

+
+
+A durable mailbox typically doesn't implements transactions for current message. It's possible
 if the actor crashes after receiving a message, but before completing processing of
 it, that the message could be lost.

-
-You configure durable mailboxes through the dispatcher, as described in
-:ref:`DurableMailbox.General` with the following mailbox type.
-
-Config::
-
-  my-dispatcher {
-    mailbox-type = akka.actor.mailbox.FileBasedMailboxType
-  }

 You can also configure and tune the file-based durable mailbox. This is done in
 the ``akka.actor.mailbox.file-based`` section in the :ref:`configuration`.

+How to implement a durable mailbox
+==================================
+
+Here is an example of how to implement a custom durable mailbox. Essentially it consists of
+a configurator (MailboxType) and a queue implementation (DurableMessageQueue).
+
+The envelope contains the message sent to the actor, and information about sender. It is the
+envelope that needs to be stored. As a help utility you can mixin DurableMessageSerialization
+to serialize and deserialize the envelope using the ordinary :ref:`serialization-scala`
+mechanism. This optional and you may store the envelope data in any way you like.
+
+.. includecode:: code/akka/docs/actor/mailbox/DurableMailboxDocSpec.scala
+   :include: custom-mailbox
+
+To facilitate testing of a durable mailbox you may use ``DurableMailboxSpec`` as base class.
+It implements a few basic tests and helps you setup the a fixture. More tests can be
+added in concrete subclass like this:
+
+.. includecode:: code/akka/docs/actor/mailbox/DurableMailboxDocSpec.scala
+   :include: custom-mailbox-test
+
+You find DurableMailboxDocSpec in ``akka-mailboxes-common-test-2.1-SNAPSHOT.jar``.
+Add this dependency::
+
+  "com.typesafe.akka" % "akka-mailboxes-common-test" % "2.1-SNAPSHOT"
+
+For more inspiration you can look at the old implementations based on Redis, MongoDB, Beanstalk,
+and ZooKeeper, which can be found in Akka git repository tag v2.0.1.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- restructure message classes in sealed traits according to message flow
  direction and include confirmed/unconfirmed status in the type
- add GetAddress query for obtaining the remote transport address of
  another test participant
- add reconnects to Player
- add small DSL with runOn(node...), ifNode(node...)()()
  and node():ActorPath
- rewrite TestConductorSpec to use that DSL and run within a single test
  procedure instead of separate NodeX classes
- hook up that test into current multi-jvm infrastructure temporarily

Subject: [PATCH 057/538] Added verification that a BalancingDispatcher can not
 be used with any kind of Router (impl + test).
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Also had to 'ignore' one test that violates this principle. Should be looked into later.

 ==================
 
+The purpose of the Akka Microkernel is to offer a bundling mechanism so that you can distribute
+an Akka application as a single payload, without the need to run in a Java Application Server or manually
+having to create a launcher script.

+This will prevent the client to send these messages to the server:
+
+* ``Create``
+* ``Recreate``
+* ``Suspend``
+* ``Resume``
+* ``Terminate``
+* ``Supervise``
+* ``ChildTerminated``
+* ``Link``
+* ``Unlink``
+
+Here is how to turn it on in the config::
+
+    akka {
+      actor {
+        remote {
+          untrusted-mode = on
+        }
+      }
+    }
+
+Secure Cookie Handshake
+-----------------------
+
+Akka remoting also allows you to specify a secure cookie that will be exchanged and ensured to be identical
+in the connection handshake between the client and the server. If they are not identical then the client
+will be refused to connect to the server.
+
+The secure cookie can be any kind of string. But the recommended approach is to generate a cryptographically
+secure cookie using this script ``$AKKA_HOME/scripts/generate_config_with_secure_cookie.sh`` or from code
+using the ``akka.util.Crypt.generateSecureCookie()`` utility method.
+
+You have to ensure that both the connecting client and the server have the same secure cookie as well
+as the ``require-cookie`` option turned on.
+
+Here is an example config::
+
+    akka {
+      actor {
+        remote {
+          netty {
+            secure-cookie = "090A030E0F0A05010900000A0C0E0C0B03050D05"
+            require-cookie = on

Subject: [PATCH 119/538] make failure injection idempotent

- instead of creating local top-level actors per pipeline, just create
  one system actor through which everything is sent
- this enables storing settings (like what to throttle how) within this
  actor and applying settings when connections come up later
- it also gets rid of the blocking actor creation from
  NetworkFailureInjector, fixing the dead-lock
- moved also the ServerFSMs to be children of the Controller
- all actors have proper names now for easier debugging

+.. note::
+  
+  ``ActorPath.toStringWithAddress`` only differs from ``toString`` if the
+  address does not already have ``host`` and ``port`` components, i.e. it only
+  inserts address information for local addresses.
+
+This assumes that serialization happens in the context of sending a message
+through the remote transport. There are other uses of serialization, though,
+e.g. storing actor references outside of an actor application (database,
+durable mailbox, etc.). In this case, it is important to keep in mind that the
+address part of an actor’s path determines how that actor is communicated with.
+Storing a local actor path might be the right choice if the retrieval happens
+in the same logical context, but it is not enough when deserializing it on a
+different network host: for that it would need to include the system’s remote
+transport address. An actor system is not limited to having just one remote
+transport per se, which makes this question a bit more interesting.
+
+In the general case, the local address to be used depends on the type of remote
+address which shall be the recipient of the serialized information. Use
+:meth:`ActorRefProvider.getExternalAddressFor(remoteAddr)` to query the system
+for the appropriate address to use when sending to ``remoteAddr``:
+
+.. includecode:: code/akka/docs/serialization/SerializationDocTestBase.java
+   :include: external-address
+
+This requires that you know at least which type of address will be supported by
+the system which will deserialize the resulting actor reference; if you have no
+concrete address handy you can create a dummy one for the right protocol using
+``new Address(protocol, "", "", 0)`` (assuming that the actual transport used is as
+lenient as Akka’s RemoteActorRefProvider).
+
+There is a possible simplification available if you are just using the default
+:class:`NettyRemoteTransport` with the :meth:`RemoteActorRefProvider`, which is
+enabled by the fact that this combination has just a single remote address:
+
+.. includecode:: code/akka/docs/serialization/SerializationDocTestBase.java
+   :include: external-address-default
+
+This solution has to be adapted once other providers are used (like the planned
+extensions for clustering).

+  ``ActorPath.toStringWithAddress`` only differs from ``toString`` if the
+  address does not already have ``host`` and ``port`` components, i.e. it only
+  inserts address information for local addresses.
+
+This assumes that serialization happens in the context of sending a message
+through the remote transport. There are other uses of serialization, though,
+e.g. storing actor references outside of an actor application (database,
+durable mailbox, etc.). In this case, it is important to keep in mind that the
+address part of an actor’s path determines how that actor is communicated with.
+Storing a local actor path might be the right choice if the retrieval happens
+in the same logical context, but it is not enough when deserializing it on a
+different network host: for that it would need to include the system’s remote
+transport address. An actor system is not limited to having just one remote
+transport per se, which makes this question a bit more interesting.
+
+In the general case, the local address to be used depends on the type of remote
+address which shall be the recipient of the serialized information. Use
+:meth:`ActorRefProvider.getExternalAddressFor(remoteAddr)` to query the system
+for the appropriate address to use when sending to ``remoteAddr``:
+
+.. includecode:: code/akka/docs/serialization/SerializationDocSpec.scala
+   :include: external-address
+
+This requires that you know at least which type of address will be supported by
+the system which will deserialize the resulting actor reference; if you have no
+concrete address handy you can create a dummy one for the right protocol using
+``Address(protocol, "", "", 0)`` (assuming that the actual transport used is as
+lenient as Akka’s RemoteActorRefProvider).
+
+There is a possible simplification available if you are just using the default
+:class:`NettyRemoteTransport` with the :meth:`RemoteActorRefProvider`, which is
+enabled by the fact that this combination has just a single remote address:
+
+.. includecode:: code/akka/docs/serialization/SerializationDocSpec.scala
+   :include: external-address-default
+
+This solution has to be adapted once other providers are used (like the planned
+extensions for clustering).

 In the above code ``readRequest`` takes the results of 3 different ``Iteratees`` (``readRequestLine``, ``readHeaders``, ``readBody``) and combines them into a single ``Request`` object. ``readRequestLine`` actually returns a tuple, so we extract it's individual components. ``readBody`` depends on values contained within the header section, so we must pass those to the method.

+Different Testing Frameworks
+============================
+
+Akka’s own test suite is written using `ScalaTest `_,
+which also shines through in documentation examples. However, the TestKit and
+its facilities do not depend on that framework, you can essentially use
+whichever suits your development style best.
+
+This section contains a collection of known gotchas with some other frameworks,
+which is by no means exhaustive and does not imply endorsement or special
+support.
+
+Specs2
+------
+
+Some `Specs2 `_ users have contributed examples of how to work around some clashes which may arise:
+
+* Mixing TestKit into :class:`org.specs2.mutable.Specification` results in a
+  name clash involving the ``end`` method (which is a private variable in
+  TestKit and an abstract method in Specification); if mixing in TestKit first,
+  the code may compile but might then fail at runtime. The work-around—which is
+  actually beneficial also for the third point—is to apply the TestKit together
+  with :class:`org.specs2.specification.Scope`.
+* The Specification traits provide a :class:`Duration` DSL which uses partly
+  the same method names as :class:`akka.util.Duration`, resulting in ambiguous
+  implicits if ``akka.util.duration._`` is imported. The work-around is to use
+  the Specification variants and supply an implicit conversion to the Akka
+  Duration. This conversion is not supplied with the Akka distribution because
+  that would mean that our JAR files would dependon Specs2, which is not
+  justified by this little feature.
+* Specifications are by default executed concurrently, which requires some care
+  when writing the tests or alternatively the ``sequential`` keyword.
+
+You can use the following two examples as guidelines:

+######################
+
+This section lists common actor patterns which have been found to be useful,
+elegant or instructive. Anything is welcome, example topics being message
+routing strategies, supervision patterns, restart handling, etc. As a special
+bonus, additions to this section are marked with the contributor’s name, and it
+would be nice if every Akka user who finds a recurring pattern in his or her
+code could share it for the profit of all. Where applicable it might also make
+sense to add to the ``akka.pattern`` package for creating an `OTP-like library
+`_.
+
+Template Pattern
+================
+
+*Contributed by: N. N.*
+
+This is an especially nice pattern, since it does even come with some empty example code:
+
+.. includecode:: code/docs/pattern/JavaTemplate.java
+   :include: all-of-it
+   :exclude: uninteresting-stuff
+
+.. note::
+
+   Spread the word: this is the easiest way to get famous!
+
+Please keep this pattern at the end of this file.

Subject: [PATCH 183/538] Added LeaderDowning spec for testing that the leader
 automatically is downing an unreachable node. Fixes 2112.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- tests downing a node at the end of the node ring
- tests downing a node in the middle of the node ring
- added some more utility stuff to the MultiNodeClusterSpec

Subject: [PATCH 197/538] Test tags not working as expected, see #2145

* Tests tagged with timing or long-running are excluded by default,
  as before
* Use -Dakka.test.tags.include=long-running,timing to run all
  untagged and also tests tagged with long-running or timing
* Use -Dakka.test.tags.only=timing,long-running to only run
  tests tagged with long-running or timing, i.e. untagged tests,
  or tests tagged with something else are not run
* I think the above two parameters covers our needs, but there is
  also -Dakka.test.tags.exclude=some-other to be able to exclude
  tests that are included by default

-/**
- * An immutable map from config paths to config values.
- *
- * 

- * Contrast with {@link ConfigObject} which is a map from config keys,
- * rather than paths, to config values. A {@code Config} contains a tree of
- * {@code ConfigObject}, and {@link Config#root()} returns the tree's root
- * object.
- *
- * 

- * Throughout the API, there is a distinction between "keys" and "paths". A key
- * is a key in a JSON object; it's just a string that's the key in a map. A
- * "path" is a parseable expression with a syntax and it refers to a series of
- * keys. Path expressions are described in the spec for
- * Human-Optimized Config Object Notation. In brief, a path is
- * period-separated so "a.b.c" looks for key c in object b in object a in the
- * root object. Sometimes double quotes are needed around special characters in
- * path expressions.
- *
- * 

- * The API for a {@code Config} is in terms of path expressions, while the API
- * for a {@code ConfigObject} is in terms of keys. Conceptually, {@code Config}
- * is a one-level map from paths to values, while a
- * {@code ConfigObject} is a tree of nested maps from keys to values.
- *
- * 

- * Use {@link ConfigUtil#joinPath} and {@link ConfigUtil#splitPath} to convert
- * between path expressions and individual path elements (keys).
- *
- * 

- * Another difference between {@code Config} and {@code ConfigObject} is that
- * conceptually, {@code ConfigValue}s with a {@link ConfigValue#valueType()
- * valueType()} of {@link ConfigValueType#NULL NULL} exist in a
- * {@code ConfigObject}, while a {@code Config} treats null values as if they
- * were missing.
- *
- * 

- * {@code Config} is an immutable object and thus safe to use from multiple
- * threads. There's never a need for "defensive copies."
- *
- * 

- * The "getters" on a {@code Config} all work in the same way. They never return
- * null, nor do they return a {@code ConfigValue} with
- * {@link ConfigValue#valueType() valueType()} of {@link ConfigValueType#NULL
- * NULL}. Instead, they throw {@link ConfigException.Missing} if the value is
- * completely absent or set to null. If the value is set to null, a subtype of
- * {@code ConfigException.Missing} called {@link ConfigException.Null} will be
- * thrown. {@link ConfigException.WrongType} will be thrown anytime you ask for
- * a type and the value has an incompatible type. Reasonable type conversions
- * are performed for you though.
- *
- * 

- * If you want to iterate over the contents of a {@code Config}, you can get its
- * {@code ConfigObject} with {@link #root()}, and then iterate over the
- * {@code ConfigObject} (which implements java.util.Map). Or, you
- * can use {@link #entrySet()} which recurses the object tree for you and builds
- * up a Set of all path-value pairs where the value is not null.
- *
- * 

- * Do not implement {@code Config}; it should only be implemented by
- * the config library. Arbitrary implementations will not work because the
- * library internals assume a specific concrete implementation. Also, this
- * interface is likely to grow new methods over time, so third-party
- * implementations will break.

-     * ${foo.bar} will be replaced with the result of
-     * getValue("foo.bar").
-     *
-     * 

-     * This method uses {@link ConfigResolveOptions#defaults()}, there is
-     * another variant {@link Config#resolve(ConfigResolveOptions)} which lets
-     * you specify non-default options.
-     *
-     * 

-     * A given {@link Config} must be resolved before using it to retrieve
-     * config values, but ideally should be resolved one time for your entire
-     * stack of fallbacks (see {@link Config#withFallback}). Otherwise, some
-     * substitutions that could have resolved with all fallbacks available may
-     * not resolve, which will be a user-visible oddity.
-     *
-     * 

-     * resolve() should be invoked on root config objects, rather
-     * than on a subtree (a subtree is the result of something like
-     * config.getConfig("foo")). The problem with
-     * resolve() on a subtree is that substitutions are relative to
-     * the root of the config and the subtree will have no way to get values

-     * would be detected later when trying to use the config, but it's often
-     * more user-friendly to fail right away when loading the config.
-     *
-     * 

-     * Using this method is always optional, since you can "fail late" instead.
-     *
-     * 

-     * You must restrict validation to paths you "own" (those whose meaning are
-     * defined by your code module). If you validate globally, you may trigger
-     * errors about paths that happen to be in the config but have nothing to do
-     * with your module. It's best to allow the modules owning those paths to
-     * validate them. Also, if every module validates only its own stuff, there
-     * isn't as much redundant work being done.
-     *
-     * 

-     * If no paths are specified in checkValid()'s parameter list,
-     * validation is for the entire config.
-     *
-     * 

-     * If you specify paths that are not in the reference config, those paths
-     * are ignored. (There's nothing to validate.)
-     *
-     * 

-     * Here's what validation involves:
-     *
-     * 
    
-     * 
  • All paths found in the reference config must be present in this
-     * config or an exception will be thrown.

-     * Some changes in type from the reference config to this config will cause
-     * an exception to be thrown. Not all potential type problems are detected,
-     * in particular it's assumed that strings are compatible with everything
-     * except objects and lists. This is because string types are often "really"
-     * some other type (system properties always start out as strings, or a
-     * string like "5ms" could be used with {@link #getMilliseconds}). Also,
-     * it's allowed to set any type to null or override null with any type.
-     * 
  • 
-     * Any unresolved substitutions in this config will cause a validation
-     * failure; both the reference config and this config should be resolved
-     * before validation. If the reference config is unresolved, it's a bug in
-     * the caller of this method.
-     * 

-     *
-     * 

-     * If you want to allow a certain setting to have a flexible type (or
-     * otherwise want validation to be looser for some settings), you could
-     * either remove the problematic setting from the reference config provided
-     * to this method, or you could intercept the validation exception and
-     * screen out certain problems. Of course, this will only work if all other
-     * callers of this method are careful to restrict validation to their own
-     * paths, as they should be.
-     *
-     * 

-     * If validation fails, the thrown exception contains a list of all problems
-     * found. See {@link ConfigException.ValidationFailed#problems}. The
-     * exception's getMessage() will have all the problems
-     * concatenated into one huge string, as well.
-     *
-     * 

-     * Again, checkValid() can't guess every domain-specific way a
-     * setting can be invalid, so some problems may arise later when attempting
-     * to use the config. checkValid() is limited to reporting
-     * generic, but common, problems such as missing settings and blatant type
-     * incompatibilities.

- * 

- * Use {@link ConfigUtil#joinPath} and {@link ConfigUtil#splitPath} to convert
- * between path expressions and individual path elements (keys).
- *
- * 

- * A {@code ConfigObject} may contain null values, which will have
- * {@link ConfigValue#valueType()} equal to {@link ConfigValueType#NULL}. If
- * {@code get()} returns Java's null then the key was not present in the parsed
- * file (or wherever this value tree came from). If {@code get()} returns a
- * {@link ConfigValue} with type {@code ConfigValueType#NULL} then the key was
- * set to null explicitly in the config file.
- *
- * 

- * Do not implement {@code ConfigObject}; it should only be implemented
- * by the config library. Arbitrary implementations will not work because the
- * library internals assume a specific concrete implementation. Also, this

-     * Creates a ConfigValue from a plain Java boxed value, which may be a
-     * Boolean, Number, String, Map, Iterable, or null. A Map must be a Map from
-     * String to more values that can be supplied to fromAnyRef(). An Iterable
-     * must iterate over more values that can be supplied to fromAnyRef(). A Map
-     * will become a ConfigObject and an Iterable will become a ConfigList. If
-     * the Iterable is not an ordered collection, results could be strange,
-     * since ConfigList is ordered.
-     *
-     * 

-     * In a Map passed to fromAnyRef(), the map's keys are plain keys, not path
-     * expressions. So if your Map has a key "foo.bar" then you will get one
-     * object with a key called "foo.bar", rather than an object with a key
-     * "foo" containing another object with a key "bar".
-     *

-     * ConfigValue. It should normally be the name of the file the values came
-     * from, or something short describing the value such as "default settings".
-     * The originDescription is prefixed to error messages so users can tell
-     * where problematic values are coming from.
-     *
-     * 

-     * Supplying the result of ConfigValue.unwrapped() to this function is
-     * guaranteed to work and should give you back a ConfigValue that matches
-     * the one you unwrapped. The re-wrapped ConfigValue will lose some
-     * information that was present in the original such as its origin, but it
-     * will have matching values.
-     *
-     * 

-     * This function throws if you supply a value that cannot be converted to a

-     * should never handle the exception. Just fix your program (or report a bug

-An API for loading and using configuration files, see the project site
-for more information.
-

-
-

-Typically you would load configuration with a static method from {@link com.typesafe.config.ConfigFactory} and then use
-it with methods in the {@link com.typesafe.config.Config} interface.
-

-
-

-An application can simply call {@link com.typesafe.config.ConfigFactory#load()} and place
-its configuration in "application.conf" on the classpath.
-If you use the default configuration from {@link com.typesafe.config.ConfigFactory#load()}
-there's no need to pass a configuration to your libraries
-and frameworks, as long as they all default to this same default, which they should.
-

-
-

-A library or framework should ship a file "reference.conf" in its jar, and allow an application to pass in a
-{@link com.typesafe.config.Config} to be used for the library. If no {@link com.typesafe.config.Config} is provided,
-call {@link com.typesafe.config.ConfigFactory#load()}
-to get the default one. Typically a library might offer two constructors, one with a Config parameter
-and one which uses {@link com.typesafe.config.ConfigFactory#load()}.
-

-
-

-You can find an example app and library on GitHub.

Subject: [PATCH 203/538] Port all MultiJvm tests to MultiNode, see #1935

* Moved akka-remote/multi-jvm test to akka-remote-tests/multi-jvm
* Removed old test utilities that are replaced by testconductor
* Removed multi-jvm from akka-remote build, these tests are now in
  akka-remote-tests
* Removed test dependencies in build that are not needed any longer
* DirectRoutedRemoteActorMultiJvmSpec replaced with
  NewRemoteActorMultiJvmSpec, same thing

Subject: [PATCH 249/538] * Add Circuit Breaker to akka.pattern for general
 use. Circuit breaker implementation as described by Michael T. Nygard in
 Release It!. Fixes #1734

  * Uses finite state machine for three states: Closed, Open, Half-Open
    * Closed state allows calls through, and on sequential failures exceeding the max# set - transitions to Open state. Intervening successes cause the failure count to reset to 0
    * Open state throws a CircuitOpenException on every call until the reset timeout is reached which causes a transition to Half-Open state
    * Half-Open state will allow the next single call through, if it succeeds - transition to Closed state, if it fails - transition back to Open state, starting the reset timer again
  * Allow configuration for the call and reset timeouts, as well as the maximum number of sequential failures before opening
  * Supports async or synchronous call protection
  * Callbacks are supported for state entry into Closed, Open, Half-Open.  These are run in the supplied execution context
  * Both thrown exceptions and calls exceeding max call time are considered failures
  * Uses akka scheduler for timer events
  * Integrated into File-Based durable mailbox
  * Sample documented for other durable mailboxes

+###############
+Circuit Breaker
+###############
+
+==================
+Why are they used?
+==================
+A circuit breaker is used to provide stability and prevent cascading failures in distributed
+systems.  These should be used in conjunction with judicious timeouts at the interfaces between
+remote systems to prevent the failure of a single component from bringing down all components.
+
+As an example, we have a web application interacting with a remote third party web service.  
+Let's say the third party has oversold their capacity and their database melts down under load.  
+Assume that the database fails in such a way that it takes a very long time to hand back an
+error to the third party web service.  This in turn makes calls fail after a long period of 
+time.  Back to our web application, the users have noticed that their form submissions take
+much longer seeming to hang.  Well the users do what they know to do which is use the refresh
+button, adding more requests to their already running requests.  This eventually causes the 
+failure of the web application due to resource exhaustion.  This will affect all users, even
+those who are not using functionality dependent on this third party web service.
+
+Introducing circuit breakers on the web service call would cause the requests to begin to 
+fail-fast, letting the user know that something is wrong and that they need not refresh 
+their request.  This also confines the failure behavior to only those users that are using
+functionality dependent on the third party, other users are no longer affected as there is no
+resource exhaustion.  Circuit breakers can also allow savvy developers to mark portions of
+the site that use the functionality unavailable, or perhaps show some cached content as 
+appropriate while the breaker is open.
+
+The Akka library provides an implementation of a circuit breaker called 
+:class:`akka.pattern.CircuitBreaker` which has the behavior described below.
+
+=================
+What do they do?
+=================
+* During normal operation, a circuit breaker is in the `Closed` state:
+	* Exceptions or calls exceeding the configured `callTimeout` increment a failure counter
+	* Successes reset the failure count to zero 
+	* When the failure counter reaches a `maxFailures` count, the breaker is tripped into `Open` state
+* While in `Open` state:
+	* All calls fail-fast with a :class:`CircuitBreakerOpenException`
+	* After the configured `resetTimeout`, the circuit breaker enters a `Half-Open` state
+* In `Half-Open` state:
+	* The first call attempted is allowed through without failing fast
+	* All other calls fail-fast with an exception just as in `Open` state
+	* If the first call succeeds, the breaker is reset back to `Closed` state
+	* If the first call fails, the breaker is tripped again into the `Open` state for another full `resetTimeout`
+* State transition listeners: 
+	* Callbacks can be provided for every state entry via `onOpen`, `onClose`, and `onHalfOpen`
+	* These are executed in the :class:`ExecutionContext` provided. 
+

+		Open [ fillcolor = red2 ];

+
+Here's how a :class:`CircuitBreaker` would be configured for:
+  * 5 maximum failures
+  * a call timeout of 10 seconds 
+  * a reset timeout of 1 minute

+Call Protection
+---------------
+
+Here's how the :class:`CircuitBreaker` would be used to protect an asynchronous
+call as well as a synchronous one:
+
+^^^^^^^
+Scala

+
+^^^^^^
+Java
+^^^^^^
+
+.. includecode:: code/docs/circuitbreaker/DangerousJavaActor.java
+   :include: circuit-breaker-usage
+
+.. note::
+
+	Using the :class:`CircuitBreaker` companion object's `apply` or `create` methods
+	will return a :class:`CircuitBreaker` where callbacks are executed in the caller's thread.
+	This can be useful if the asynchronous :class:`Future` behavior is unnecessary, for
+	example invoking a synchronous-only API.

Subject: [PATCH 252/538] Added implementation of the LEAVE command for a
 cluster node.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Added implementation of the LEAVE command for a cluster node
* Changed the meaning of Member.isUnavailable to only DOWN and REMOVED
* Removed EXIT and UP as user commands
* Fixed Cluster.self to fall back to checking for itself in the gossip.overview.unreachable set.
* Added Leader action transitioning from LEAVING -> EXITING
* Improved comments

 support.
 
+When you need it to be a trait
+------------------------------
+
+If for some reason it is a problem to inherit from :class:`TestKit` due to it
+being a concrete class instead of a trait, there’s :class:`TestKitBase`:
+
+.. includecode:: code/docs/testkit/TestkitDocSpec.scala
+   :include: test-kit-base
+   :exclude: put-your-test-code-here
+
+The ``implicit lazy val system`` must be declared exactly like that (you can of
+course pass arguments to the actor system factory as needed) because trait
+:class:`TestKitBase` needs the system during its construction.

Subject: [PATCH 275/538] Replace 'after' barrier with explicit barrier inside
 test method.

* It's no problem using after, but scalatest will output the test method
  as completed (green) before running after, so it looks confusing in the logs
* Using unique barrier names adds extra traceability in case of failures.

Subject: [PATCH 276/538] make cleanUp of systemMessages atomic

- extend systemDrain to take the new contents which shall be switched in
- make NoMessage placeholder which will signal final closing of the
  mailbox
- put that in when cleaning up, and check it when enqueuing

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Renamed all 'frequency' to 'interval'
- Split up NodeJoinAndUpSpec and into NodeJoinSpec and NodeUpSpec.
- Split up MembershipChangeListenerJoinAndUpSpec and into MembershipChangeListenerJoinSpec and MembershipChangeListenerUpSpec.
- Added utility method 'startClusterNode()'
- Fixed race in register listener and telling node to leave
- Removed 'after' blocks
- Cleaned up unused code
- Improved comments

From c64775857900ffa168e6d68a7314ff82f3ad8f10 Mon Sep 17 00:00:00 2001
From: Peter Badenhorst 
Date: Tue, 5 Jun 2012 13:44:05 +0200
Subject: [PATCH 292/538] Updated to support 3 different random number
 generators:

1) SecureRandom supported by Java (default)
2) SHA1PRNG (causes problems on Linux)
3) Various versions of the AES Counter RNG (faster than default at generating random data)

+##############################
+Testing Actor Systems (Java)
+##############################
+
+Due to the conciseness of test DSLs available for Scala, it may be a good idea
+to write the test suite in that language even if the main project is written in
+Java. If that is not desirable, you can also use :class:`TestKit` and friends
+from Java, albeit with more verbose syntax Munish Gupta has `published a nice
+post `_
+showing several patterns you may find useful, and for reference documentation
+please refer to :ref:`akka-testkit` until that section has been ported over to
+cover Java in full.

Subject: [PATCH 319/538] make system.actorOf non-blocking (*), see #2031

(*) that actually depends on whether provider.actorOf blocks, which
currently MAY happen when actor creation triggers a remote connection

- properly CAS childrenRefs within ActorCell, making it safe to update
  from the outside
- add reserve/unreserve to ChildrenContainer and move uniqueness check
  there
- when creating, first reserve, then add the actor; unreserve if
  provider.actorOf did fail

Subject: [PATCH 330/538] Use all heartbeats in failure detector, see #2182

* Failure detector didn't use hearbeat 1 and 2
* Included heartbeat 2 in ordinary stats
* For heartbeat 1 use guess stats,
  important so that connections with only one heartbeat
  becomes unavailble, the guess corresponds to 1 second interval
  which results in phi > 8 after 18 seconds
* Improved AccrualFailureDetectorSpec

Subject: [PATCH 343/538] Misc fixes after FailureDetectorPuppet and
 abstraction review
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Moved FailureDetectorPuppet to its own file in src/test.
- Removed 'phi' method from FailureDetector public API.
- Throwing exception instead of falling back to default if we can't load the custom FD.
- Removed add-connection method in FailureDetectorPuppet.

Subject: [PATCH 347/538] Created FailureDetectorStrategy with two
 implementations: FailureDetectorPuppetStrategy and
 AccrualFailureDetectorStrategy.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Created FailureDetectorStrategy base trait.
- Created FailureDetectorPuppetStrategy.
- Created AccrualFailureDetectorStrategy.
- Created two versions of LeaderDowningNodeThatIsUnreachableMultiJvmSpec
    - LeaderDowningNodeThatIsUnreachableWithFailureDetectorPuppet
    - LeaderDowningNodeThatIsUnreachableWithAccrualFailureDetector
- Added AccrualFailureDetectorStrategy to all the remaining tests - will be split up into two versions shortly.

Subject: [PATCH 351/538] Used RemoteCommunicationSpec as a template to
 implement a functional spec to test SSL communication.

1) Converted provider and related RNG's from Java to Scala
2) Added trust/key stores for testing purposes
3) As stated in the test comments, Internet access is required for the 2 'Secure' RNG variants to function within the time limit.
4) Fixed unnecessary imports

Subject: [PATCH 386/538] make system.actorOf() non-blocking (and working), see
 #2031
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- introducing RepointableActorRef, which starts out with an
  UnstartedActorCell which can cheaply be created; the Supervise()
  message will trigger child.activate() in the supervisor, which means
  that the actual creation (now with normal ActorCell) happens exactly
  in the right place and with the right semantics. Messages which were
  enqueued to the dummy cell are transferred atomically into the
  ActorCell (using normal .tell()), so message sends keep working
  exactly as they used to
- this enables getting rid of the brittle synchronization around
  RoutedActorRef by replacing that one with a RepointableActorRef
  subclass which creates RoutedActorCells upon activate(), with the nice
  benefit that there is no hurry then to get it right because the new
  cell is constructed “on the side”

misc fixes:

- InvalidMessageException is now actually enforced when trying to send
  “null”
- Mailboxes may be created without having an ActorCell, which can come
  in handy later, because the cell is only needed when this mailbox is
  going to be scheduled on some executor
- remove occurrences of Props(), which is equivalent to Props[Nothing],
  which is equivalent to «bug»
- add test case which verifies that context.actorOf is still synchronous
- plus all the stuff I have forgotten.

Subject: [PATCH 389/538] Correction of gossip merge when joining, see #2204

The problem:
* Node that is Up joins a cluster and becomes Joining in that cluster
* The joining node receives gossip, which results in conflict,
  merge results in Up
* It became Up in the new cluster without passing the ordinary leader
  action to move it to Up

The solution:
* Change priority order of Up and Joining so that Joining is used when
  merging

Subject: [PATCH 407/538] Redesign of life-cycle management of EXITING ->
 REMOVED. Fixes #2177.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Removed REMOVED as explicit valid member state
- Implemented leader moving either itself or other member from EXITING -> REMOVED
- Added sending Remove message for removed node to shut down itself
- Fixed a few bugs
- Removed 'remove' from Cluster and JMX interface
- Added bunch of ScalaDoc
- Added isRunning method

Subject: [PATCH 485/538] Reintroduce 'seed' nodes, see #2219

* Implement the join to seed nodes process
  When a new node is started started it sends a message to all
  seed nodes and then sends join command to the one that answers
  first.
* Configuration of seed-nodes and auto-join
* New JoinSeedNodeSpec that verifies the auto join to seed nodes
* In tests seed nodes are configured by overriding seedNodes
  function, since addresses are not known before start
* Deputy nodes are the live members of the seed nodes (not sure if
  that will be the final solution, see ticket 2252
* Updated cluster.rst with latest info about deputy and seed nodes

+Seed Nodes
+^^^^^^^^^^
+
+The seed nodes are configured contact points for inital join of the cluster.
+When a new node is started started it sends a message to all seed nodes and 
+then sends join command to the one that answers first.
+
+It is possible to turn off automatic join.
+
 Deputy Nodes
 ^^^^^^^^^^^^
 
-After gossip convergence a set of ``deputy`` nodes for the cluster can be
-determined. As with the ``leader``, there is no ``deputy`` election process,
-the deputies can always be recognised deterministically by any node whenever there
-is gossip convergence. The list of ``deputy`` nodes is simply the N - 1 number
-of nodes (e.g. starting with the first node after the ``leader``) in sorted order.
+The deputy nodes are the live members of the configured seed nodes. 
+It is preferred to use deputy nodes in different racks/data centers.
 
 The nodes defined as ``deputy`` nodes are just regular member nodes whose only
 "special role" is to help breaking logical partitions as seen in the gossip

Subject: [PATCH 522/538] Improve efficiency of gossip, see #2193 and #2253

* Essentially as already described in cluster specification,
  but now fully implemented and tested with LargeClusterSpec
* Gossip to nodes with different view (using seen table)
  with certain probability
* Gossip chat, gossip back to sender
* Immediate gossip to joining node
* Updated some tests to reflect current implementation
