Overview

-
-

Modern concurrency tools for Ruby. Inspired by Erlang, Clojure, Scala, Haskell, -F#, C#, Java, and classic concurrency patterns.

- -

The design goals of this gem are:

- -
    -
  • Stay true to the spirit of the languages providing inspiration
    • -
  • But implement in a way that makes sense for Ruby
    • -
  • Keep the semantics as idiomatic Ruby as possible
    • -
  • Support features that make sense in Ruby
    • -
  • Exclude features that don't make sense in Ruby
    • -
  • Be small, lean, and loosely coupled
    • -
- - -
-
-
- - -

- - + (Object) abort_transaction - - - - - -

-

Abort a currently running transaction - see Concurrent::atomically.

-end
-
-
- -
-

- - + (Object) atomically - - - - - -

-
-

Run a block that reads and writes TVars as a single atomic transaction. -With respect to the value of TVar objects, the transaction is atomic, in -that it either happens or it does not, consistent, in that the TVar -objects involved will never enter an illegal state, and isolated, in that -transactions never interfere with each other. You may recognise these -properties from database transactions.

- -

There are some very important and unusual semantics that you must be aware of:

- -
    -

  • Most importantly, the block that you pass to atomically may be executed -more than once. In most cases your code should be free of -side-effects, except for via TVar.

    • -

  • If an exception escapes an atomically block it will abort the transaction.

    • -

  • It is undefined behaviour to use callcc or Fiber with atomically.

    • -

  • If you create a new thread within an atomically, it will not be part of -the transaction. Creating a thread counts as a side-effect.

    • -
- -

Transactions within transactions are flattened to a single transaction.

- - -
-
-
- -
-

Examples:

- - - 
a = new TVar(100_000)
-b = new TVar(100)
-
-Concurrent::atomically do
-  a.value -= 10
-  b.value += 10

Only change this option if you know what you are doing! -When this is set to true (the default) then at_exit handlers -will be registered automatically for all thread pools to -ensure that they are shutdown when the application ends. When -changed to false, the at_exit handlers will be circumvented -for all Concurrent Ruby thread pools running within the -application. Even those created within other gems used by the -application.

Returns:

The dataflow task itself is also a Future value, so you can build up a graph of these tasks, each of which is run when all the data and other tasks it depends on are available or completed.

Our syntax is somewhat related to that of Akka's flow and Habanero Java's DataDrivenFuture. However unlike Akka we don't schedule a task at all until it is ready to run, and unlike Habanero Java we pass the data values into the task instead of dereferencing them again in the task.

- -

The theory of dataflow goes back to the 70s. In the terminology of the literature, our implementation is coarse-grained, in that each task can be many instructions, and dynamic in that you can create more tasks within other tasks.

- -

Example

- -

A dataflow task is created with the dataflow method, passing in a block.

- -
task = Concurrent::dataflow { 14 }
-
- -

This produces a simple Future value. The task will run immediately, as it has no dependencies. We can also specify Future values that must be available before a task will run. When we do this we get the value of those futures passed to our block.

- -
a = Concurrent::dataflow { 1 }
-b = Concurrent::dataflow { 2 }
-c = Concurrent::dataflow(a, b) { |av, bv| av + bv }
-
- -

Using the dataflow method you can build up a directed acyclic graph (DAG) of tasks that depend on each other, and have the tasks run as soon as their dependencies are ready and there is CPU capacity to schedule them. This can help you create a program that uses more of the CPU resources available to you.

- -

Derivation

- -

This section describes how we could derive dataflow from other primitives in this library.

- -

Consider a naive fibonacci calculator.

- -
def fib(n)
-  if n < 2
-    n
-  else
-    fib(n - 1) + fib(n - 2)
-  end
-end
-
-puts fib(14) #=> 377
-
- -

We could modify this to use futures.

- -
def fib(n)
-  if n < 2
-    Concurrent::Future.new { n }
-  else
-    n1 = fib(n - 1).execute
-    n2 = fib(n - 2).execute
-    Concurrent::Future.new { n1.value + n2.value }
-  end
-end
-
-f = fib(14) #=> #<Concurrent::Future:0x000001019ef5a0 ...
-f.execute   #=> #<Concurrent::Future:0x000001019ef5a0 ...
-
-sleep(0.5)
-
-puts f.value #=> 377
-
- -

One of the drawbacks of this approach is that all the futures start, and then most of them immediately block on their dependencies. We know that there's no point executing those futures until their dependencies are ready, so let's not execute each future until all their dependencies are ready.

- -

To do this we'll create an object that counts the number of times it observes a future finishing before it does something - and for us that something will be to execute the next future.

- -
class CountingObserver
-
-  def initialize(count, &block)
-    @count = count
-    @block = block
-  end
-
-  def update(time, value, reason)
-    @count -= 1
-
-    if @count <= 0
-      @block.call()
-    end
-  end
-
-end
-
-def fib(n)
-  if n < 2
-    Concurrent::Future.new { n }.execute
-  else
-    n1 = fib(n - 1)
-    n2 = fib(n - 2)
-
-    result = Concurrent::Future.new { n1.value + n2.value }
-
-    barrier = CountingObserver.new(2) { result.execute }
-    n1.add_observer barrier
-    n2.add_observer barrier
-
-    n1.execute
-    n2.execute
-
-    result
-  end
-end
-
- -

We can wrap this up in a dataflow utility.

- -
f = fib(14) #=> #<Concurrent::Future:0x00000101fca308 ...
-sleep(0.5)
-
-puts f.value #=> 377
-
-def dataflow(*inputs, &block)
-  result = Concurrent::Future.new(&block)
-
-  if inputs.empty?
-    result.execute
-  else
-    barrier = CountingObserver.new(inputs.size) { result.execute }
-
-    inputs.each do |input|
-      input.add_observer barrier
-    end
-  end
-
-  result
-end
-
-def fib(n)
-  if n < 2
-    dataflow { n }
-  else
-    n1 = fib(n - 1)
-    n2 = fib(n - 2)
-    dataflow(n1, n2) { n1.value + n2.value }
-  end
-end
-
-f = fib(14) #=> #<Concurrent::Future:0x00000101fca308 ...
-sleep(0.5)
-
-puts f.value #=> 377
-
- -

Since we know that the futures the dataflow computation depends on are already going to be available when the future is executed, we might as well pass the values into the block so we don't have to reference the futures inside the block. This allows us to write the dataflow block as straight non-concurrent code without reference to futures.

- -
def dataflow(*inputs, &block)
-  result = Concurrent::Future.new do
-    values = inputs.map { |input| input.value }
-    block.call(*values)
-  end
-
-  if inputs.empty?
-    result.execute
-  else
-    barrier = CountingObserver.new(inputs.size) { result.execute }
-
-    inputs.each do |input|
-      input.add_observer barrier
-    end
-  end
-
-  result
-end
-
-def fib(n)
-  if n < 2
-    Concurrent::dataflow { n }
-  else
-    n1 = fib(n - 1)
-    n2 = fib(n - 2)
-    Concurrent::dataflow(n1, n2) { |v1, v2| v1 + v2 }
-  end
-end
-
-f = fib(14) #=> #<Concurrent::Future:0x000001019a26d8 ...
-sleep(0.5)
-
-puts f.value #=> 377

Overview

-
-

A ThreadLocalVar is a variable where the value is different for each thread. -Each variable may have a default value, but when you modify the variable only -the current thread will ever see that change.

- - -
-
-
- -
-

Examples:

- - - 
v = ThreadLocalVar.new(14)
-v.value #=> 14
-v.value = 2
-v.value #=> 2
- - - 
v = ThreadLocalVar.new(14)
-
-t1 = Thread.new do
-  v.value #=> 14
-  v.value = 1
-  v.value #=> 1
-end
-
-t2 = Thread.new do
-  v.value #=> 14
-  v.value = 2
-  v.value #=> 2
-end
-
-v.value #=> 14

- - - (Reference) dead_letter_routing - - - - - -

-
-

Defines an actor responsible for dead letters. Any rejected message send with -Reference#tell is sent there, a message with ivar is considered already monitored for -failures. Default behaviour is to use Context#dead_letter_routing of the parent, -so if no Context#dead_letter_routing method is overridden in parent-chain the message ends up in -Actor.root.dead_letter_routing agent which will log warning.

Overview

-
-

Actor model

- -
    -
  • Light-weighted.
    • -
  • Inspired by Akka and Erlang.
    • -
- -

Actors are sharing a thread-pool by default which makes them very cheap to create and discard. -Thousands of actors can be created allowing to brake the program to small maintainable pieces -without breaking single responsibility principles.

- -

What is an actor model?

- -

Wiki says: -The actor model in computer science is a mathematical model of concurrent computation -that treats actors as the universal primitives of concurrent digital computation: -in response to a message that it receives, an actor can make local decisions, -create more actors, send more messages, and determine how to respond to the next -message received.

- -

Why?

- -

Concurrency is hard this is one of many ways how to simplify the problem. -It is simpler to reason about actors then about locks (and all their possible states).

- -

How to use it

- -

class Counter
-  # Include context of an actor which gives this class access to reference and other information
-  # about the actor, see CoreDelegations.
-  include Concurrent::Actress::Context
-
-  # use initialize as you wish
-  def initialize(initial_value)
-    @count = initial_value
-  end
-
-  # override on_message to define actor's behaviour
-  def on_message(message)
-    case message
-    when Integer
-      @count += message
-    when :terminate
-      terminate!
-    else
-      raise 'unknown'
-    end
-  end
-end                                                # => :on_message
-
-# Create new actor naming the instance 'first'.
-# Return value is a reference to the actor, the actual actor is never returned.
-counter = Counter.spawn(:first, 5)
-    # => #<Concurrent::Actress::Reference /first (Counter)>
-
-# Tell a message and forget returning self.
-counter.tell(1)
-    # => #<Concurrent::Actress::Reference /first (Counter)>
-counter << 1
-    # => #<Concurrent::Actress::Reference /first (Counter)>
-# (First counter now contains 7.)
-
-# Send a messages asking for a result.
-counter.ask(0).class                               # => Concurrent::IVar
-counter.ask(0).value                               # => 7
-
-# Terminate the actor.
-counter.tell(:terminate)
-    # => #<Concurrent::Actress::Reference /first (Counter)>
-# Not terminated yet, it takes a while until the message is processed.
-counter.terminated?                                # => false
-# Waiting for the termination.
-counter.terminated.class                           # => Concurrent::Event
-counter.terminated.wait                            # => true
-counter.terminated?                                # => true
-# Any subsequent messages are rejected.
-counter.ask(5).wait.rejected?                      # => true
-
-# Failure on message processing terminates the actor.
-counter = Counter.spawn(:first, 0)
-    # => #<Concurrent::Actress::Reference /first (Counter)>
-counter.ask('boom').wait.rejected?                 # => true
-counter.terminated?                                # => true
-
-
-# Lets define an actor creating children actors.
-class Node
-  include Concurrent::Actress::Context
-
-  def on_message(message)
-    case message
-    when :new_child
-      spawn self.class, :child
-    when :how_many_children
-      children.size
-    when :terminate
-      terminate!
-    else

-end                                                # => :on_message
-
-# Actors are tracking parent-child relationships
-parent = Node.spawn :parent                        # => #<Concurrent::Actress::Reference /parent (Node)>
-child  = parent.tell(:new_child).ask!(:new_child)
-    # => #<Concurrent::Actress::Reference /parent/child (Node)>

- -

Messaging

- -

Messages are processed in same order as they are sent by a sender. It may interleaved with -messages form other senders though. There is also a contract in actor model that -messages sent between actors should be immutable. Gems like

- -
    -
  • Algebrick - Typed struct on steroids based on -algebraic types and pattern matching
    • -
  • Hamster - Efficient, Immutable, Thread-Safe -Collection classes for Ruby
    • -
- -

are very useful.

- -

Architecture

- -

Actors are running on shared thread poll which allows user to create many actors cheaply. -Downside is that these actors cannot be directly used to do IO or other blocking operations. -Blocking operations could starve the default_task_pool. However there are two options:

- -
    -
  • Create an regular actor which will schedule blocking operations in global_operation_pool -(which is intended for blocking operations) sending results back to self in messages.
    • -
  • Create an actor using global_operation_pool instead of global_task_pool, e.g. -AnIOActor.spawn name: :blocking, executor: Concurrent.configuration.global_operation_pool.
    • -
- -

Each actor is composed from 3 objects:

- -

Reference

- -

Reference is public interface of Actor instances. It is used for sending messages and can -be freely passed around the program. It also provides some basic information about the actor, -see CoreDelegations.

-

- -

Core

- -

Core of the actor

-

- -

Context

- -

This module is used to define actors. It can be included in any class, -only requirement is to override Context#on_message method.

-

- -

Speed

- -

Simple benchmark Actress vs Celluloid, the numbers are looking good -but you know how it is with benchmarks. Source code is in -examples/actress/celluloid_benchmark.rb. It sends numbers between x actors -and adding 1 until certain limit is reached.

- -

Benchmark legend:

- -
    -
  • mes. - number of messages send between the actors
    • -
  • act. - number of actors exchanging the messages
    • -
  • impl. - which gem is used

Overview

-
- -
- Note: -

Whole class should be considered private. An user should use Contexts and References only.

-
-
- -
- Note: -

devel: core should not block on anything, e.g. it cannot wait on children to terminate -that would eat up all threads in task pool and deadlock

-
-

Defines an actor responsible for dead letters. Any rejected message send with -Reference#tell is sent there, a message with ivar is considered already monitored for -failures. Default behaviour is to use #dead_letter_routing of the parent, -so if no #dead_letter_routing method is overridden in parent-chain the message ends up in -Actress.root.dead_letter_routing agent which will log warning.

Dynamic Method Handling

-

- This class handles dynamic methods through the method_missing method - -

- -
-

- - - (IVar) method_missing(method, *args, &block) - - - - - -

-
-

Delegates method calls to the wrapped object. For performance, -dynamically defines the given method on the delegator so that -all future calls to method will not be directed here.

- - -
-
-
-

Parameters:

-
    - -
  • - - method - - - (Symbol) - - - - — -

    the method being called

    -

  • - - - (IVar) - - - - — -

    the result of the method call

    -
    - -
    • - -
-

Raises:

-
    - -
  • - - - (NameError) - - - - — -

    the object does not respond to method method

    -
    - -

Overview

-
Deprecated.
-

Condition is a better implementation of standard Ruby ConditionVariable. The -biggest difference is the wait return value: Condition#wait returns -Condition::Result which make possible to know if waiting thread has been -woken up by an another thread (using #signal or #broadcast) or due to -timeout.

- -

Every #wait must be guarded by a locked Mutex or a ThreadError will be -risen. Although it's not mandatory, it's recommended to call also #signal -and #broadcast within the same mutex

- Note: -

Time calculations one all platforms and languages are sensitive to -changes to the system clock. To alleviate the potential problems -associated with changing the system clock while an application is running, -most modern operating systems provide a monotonic clock that operates -independently of the system clock. A monotonic clock cannot be used to -determine human-friendly clock times. A monotonic clock is used exclusively -for calculating time intervals. Not all Ruby platforms provide access to an -operating system monotonic clock. On these platforms a pure-Ruby monotonic -clock will be used as a fallback. An operating system monotonic clock is both -faster and more reliable than the pure-Ruby implementation. The pure-Ruby -implementation should be fast and reliable enough for most non-realtime -operations. At this time the common Ruby platforms that provide access to an -operating system monotonic clock are MRI 2.1 and above and JRuby (all versions).

Overview

-
-

Object references in Ruby are mutable. This can lead to serious problems when -the #value of a concurrent object is a mutable reference. Which is always the -case unless the value is a Fixnum, Symbol, or similar "primitive" data type. -Most classes in this library that expose a #value getter method do so using the -Dereferenceable mixin module.

- -

Objects with this mixin can be configured with a few options that can help protect -the program from potentially dangerous operations.

- -
    -
  • :dup_on_deref when true will call the #dup method on the value -object every time the #value method is called (default: false)
    • -
  • :freeze_on_deref when true will call the #freeze method on the value object -every time the #value method is called (default: false)
    • -
  • :copy_on_deref when given a Proc object the Proc will be run every -time the #value method is called. The Proc will be given the current -value as its only parameter and the result returned by the block will -be the return value of the #value call. When nil this option will be -ignored (default: nil)

- - - (Mutex) mutex (protected) - - - - - -

-
-

A mutex lock used for synchronizing thread-safe operations. Methods defined -by Dereferenceable are synchronized using the Mutex returned from this -method. Operations performed by the including class that operate on the -@value instance variable should be locked with this Mutex.

When multiple deref options are set the order of operations is strictly defined. -The order of deref operations is:

- -
    -
  • :copy_on_deref
    • -
  • :dup_on_deref
    • -
  • :freeze_on_deref
    • -
- -

Because of this ordering there is no need to #freeze an object created by a -provided :copy_on_deref block. Simply set :freeze_on_deref to true. -Setting both :dup_on_deref to true and :freeze_on_deref to true is -as close to the behavior of a "pure" functional language (like Erlang, Clojure, -or Haskell) as we are likely to get in Ruby.

- -

This method is thread-safe and synchronized with the internal #mutex.

- - -
-
-
- -

Returns:

-
    - -
  • - - - (Object) - - - - — -

    the current value of the object

Module: Concurrent::Edge::FutureShortcuts - - - -

- -
- - - - - - - -
Included in:

Concurrent, Concurrent, Concurrent::Edge, Concurrent::Edge
- - - -
Defined in:

Overview

-
- -
- Note: -

Edge Feature: Edge features are under active development and may change frequently. They are expected not to -keep backward compatibility (there may also lack tests and documentation). Semantic versions will -be obeyed though. Features developed in concurrent-ruby-edge are expected to move -to concurrent-ruby when final.

-
-
- -

Provides edge features, which will be added to or replace features in main gem.

- -

Contains new unified implementation of Futures and Promises which combines Features of previous Future, -Promise, IVar, Event, Probe, dataflow, Delay, TimerTask into single framework. It uses extensively -new synchronization layer to make all the paths lock-free with exception of blocking threads on #wait. -It offers better performance and does not block threads (exception being #wait and similar methods where it's -intended).

- -

Examples

-# block until evaluated
-future.value                                       # => 2

Overview

-
- -
- Note: -

Failure to properly shutdown a thread pool can lead to unpredictable results. -Please read Shutting Down Thread Pools for more information.

-
-
- -
- Note: -

When running on the JVM (JRuby) this class will inherit from JavaThreadPoolExecutor. -On all other platforms it will inherit from RubyThreadPoolExecutor.

-
-
- -

A thread pool with a set number of threads. The number of threads in the pool -is set on construction and remains constant. When all threads are busy new -tasks #post to the thread pool are enqueued until a thread becomes available. -Should a thread crash for any reason the thread will immediately be removed -from the pool and replaced.

- -

The API and behavior of this class are based on Java's FixedThreadPool

- -

Thread pools support several configuration options:

- -
    -
  • idletime: The number of seconds that a thread may be idle before being reclaimed.
    • -
  • max_queue: The maximum number of tasks that may be waiting in the work queue at -any one time. When the queue size reaches max_queue subsequent tasks will be -rejected in accordance with the configured fallback_policy.
    • -
  • stop_on_exit: When true (default) an at_exit handler will be registered which -will stop the thread pool when the application exits. See below for more information -on shutting down thread pools.
    • -
  • fallback_policy: The policy defining how rejected tasks are handled.
    • -
- -

Three fallback policies are supported:

- -
    -
  • :abort: Raise a RejectedExecutionError exception and discard the task.
    • -
  • :discard: Discard the task and return false.
    • -
  • :caller_runs: Execute the task on the calling thread.
    • -
- -

Shutting Down Thread Pools

- -

Killing a thread pool while tasks are still being processed, either by calling -the #kill method or at application exit, will have unpredictable results. There -is no way for the thread pool to know what resources are being used by the -in-progress tasks. When those tasks are killed the impact on those resources -cannot be predicted. The best practice is to explicitly shutdown all thread -pools using the provided methods:

- -
    -
  • Call #shutdown to initiate an orderly termination of all in-progress tasks
    • -
  • Call #wait_for_termination with an appropriate timeout interval an allow -the orderly shutdown to complete
    • -
  • Call #kill only when the thread pool fails to shutdown in the allotted time
    • -
- -

On some runtime platforms (most notably the JVM) the application will not -exit until all thread pools have been shutdown. To prevent applications from -"hanging" on exit all thread pools include an at_exit handler that will -stop the thread pool when the application exists. This handler uses a brute -force method to stop the pool and makes no guarantees regarding resources being -used by any tasks still running. Registration of this at_exit handler can be -prevented by setting the thread pool's constructor :stop_on_exit option to -false when the thread pool is created. All thread pools support this option.

- -
pool1 = Concurrent::FixedThreadPool.new(5) # an `at_exit` handler will be registered
-pool2 = Concurrent::FixedThreadPool.new(5, stop_on_exit: false) # prevent `at_exit` handler registration

Overview

-
- -
- Note: -

This implementation is not thread safe and performs no blocking.

-
-
- -

A queue collection in which the elements are sorted based on their -comparison (spaceship) operator <=>. Items are added to the queue -at a position relative to their priority. On removal the element -with the "highest" priority is removed. By default the sort order is -from highest to lowest, but a lowest-to-highest sort order can be -set on construction.

- -

The API is based on the Queue class from the Ruby standard library.

- -

The pure Ruby implementation, MutexPriorityQueue uses a heap algorithm -stored in an array. The algorithm is based on the work of Robert Sedgewick -and Kevin Wayne.

- -

The JRuby native implementation is a thin wrapper around the standard -library java.util.PriorityQueue.

- -

When running under JRuby the class PriorityQueue extends JavaPriorityQueue. -When running under all other interpreters it extends MutexPriorityQueue.

Overview

-
-

A counting semaphore. Conceptually, a semaphore maintains a set of permits. Each #acquire blocks if necessary -until a permit is available, and then takes it. Each #release adds a permit, -potentially releasing a blocking acquirer. -However, no actual permit objects are used; the Semaphore just keeps a count of the number available and -acts accordingly.

Overview

-
- -
- Note: -

Failure to properly shutdown a thread pool can lead to unpredictable results. -Please read Shutting Down Thread Pools for more information.

-
-
- -
- Note: -

When running on the JVM (JRuby) this class will inherit from JavaThreadPoolExecutor. -On all other platforms it will inherit from RubyThreadPoolExecutor.

-
-
- -

A thread pool with a set number of threads. The number of threads in the pool -is set on construction and remains constant. When all threads are busy new -tasks #post to the thread pool are enqueued until a thread becomes available. -Should a thread crash for any reason the thread will immediately be removed -from the pool and replaced.

- -

The API and behavior of this class are based on Java's SingleThreadExecutor

- -

Thread pools support several configuration options:

- -
    -
  • idletime: The number of seconds that a thread may be idle before being reclaimed.
    • -
  • max_queue: The maximum number of tasks that may be waiting in the work queue at -any one time. When the queue size reaches max_queue subsequent tasks will be -rejected in accordance with the configured fallback_policy.
    • -
  • stop_on_exit: When true (default) an at_exit handler will be registered which -will stop the thread pool when the application exits. See below for more information -on shutting down thread pools.
    • -
  • fallback_policy: The policy defining how rejected tasks are handled.
    • -
- -

Three fallback policies are supported:

- -
    -
  • :abort: Raise a RejectedExecutionError exception and discard the task.
    • -
  • :discard: Discard the task and return false.
    • -
  • :caller_runs: Execute the task on the calling thread.
    • -
- -

Shutting Down Thread Pools

- -

Killing a thread pool while tasks are still being processed, either by calling -the #kill method or at application exit, will have unpredictable results. There -is no way for the thread pool to know what resources are being used by the -in-progress tasks. When those tasks are killed the impact on those resources -cannot be predicted. The best practice is to explicitly shutdown all thread -pools using the provided methods:

- -
    -
  • Call #shutdown to initiate an orderly termination of all in-progress tasks
    • -
  • Call #wait_for_termination with an appropriate timeout interval an allow -the orderly shutdown to complete
    • -
  • Call #kill only when the thread pool fails to shutdown in the allotted time
    • -
- -

On some runtime platforms (most notably the JVM) the application will not -exit until all thread pools have been shutdown. To prevent applications from -"hanging" on exit all thread pools include an at_exit handler that will -stop the thread pool when the application exists. This handler uses a brute -force method to stop the pool and makes no guarantees regarding resources being -used by any tasks still running. Registration of this at_exit handler can be -prevented by setting the thread pool's constructor :stop_on_exit option to -false when the thread pool is created. All thread pools support this option.

- -
pool1 = Concurrent::FixedThreadPool.new(5) # an `at_exit` handler will be registered
-pool2 = Concurrent::FixedThreadPool.new(5, stop_on_exit: false) # prevent `at_exit` handler registration

Overview

-
-

Lazy evaluation of a block yielding an immutable result. Useful for -expensive operations that may never be needed. LazyReference is a simpler, -blocking version of Delay and has an API similar to AtomicReference. -The first time #value is called the caller will block until the -block given at construction is executed. Once the result has been -computed the value will be immutably set. Any exceptions thrown during -computation will be suppressed.

- -

Because of its simplicity LazyReference is much faster than Delay:

- -
       user     system      total        real

Overview

-
-

A synchronization object that allows one thread to wait on multiple other threads. -The thread that will wait creates a CountDownLatch and sets the initial value -(normally equal to the number of other threads). The initiating thread passes the -latch to the other threads then waits for the other threads by calling the #wait -method. Each of the other threads calls #count_down when done with its work. -When the latch counter reaches zero the waiting thread is unblocked and continues -with its work. A CountDownLatch can be used only once. Its value cannot be reset.

Overview

-
- -
- Note: -

This implementation is not thread safe and performs no blocking.

-
-
- -

A queue collection in which the elements are sorted based on their -comparison (spaceship) operator <=>. Items are added to the queue -at a position relative to their priority. On removal the element -with the "highest" priority is removed. By default the sort order is -from highest to lowest, but a lowest-to-highest sort order can be -set on construction.

- -

The API is based on the Queue class from the Ruby standard library.

- -

The pure Ruby implementation, MutexPriorityQueue uses a heap algorithm -stored in an array. The algorithm is based on the work of Robert Sedgewick -and Kevin Wayne.

- -

The JRuby native implementation is a thin wrapper around the standard -library java.util.PriorityQueue.

- -

When running under JRuby the class PriorityQueue extends JavaPriorityQueue. -When running under all other interpreters it extends MutexPriorityQueue.

Overview

-
- -
- Note: -

This implementation is not thread safe and performs no blocking.

-
-
- -

A queue collection in which the elements are sorted based on their -comparison (spaceship) operator <=>. Items are added to the queue -at a position relative to their priority. On removal the element -with the "highest" priority is removed. By default the sort order is -from highest to lowest, but a lowest-to-highest sort order can be -set on construction.

- -

The API is based on the Queue class from the Ruby standard library.

- -

The pure Ruby implementation, MutexPriorityQueue uses a heap algorithm -stored in an array. The algorithm is based on the work of Robert Sedgewick -and Kevin Wayne.

- -

The JRuby native implementation is a thin wrapper around the standard -library java.util.PriorityQueue.

- -

When running under JRuby the class PriorityQueue extends JavaPriorityQueue. -When running under all other interpreters it extends MutexPriorityQueue.

Instance Method Details

- - -
-

- - - (Integer) physical_processor_count - - - - - -

-
-

Number of physical processor cores on the current system. For performance -reasons the calculated value will be memoized on the first call.

- -

On Windows the Win32 API will be queried for the NumberOfCores from -Win32_Processor. This will return the total number "of cores for the -current instance of the processor." On Unix-like operating systems either -the hwprefs or sysctl utility will be called in a subshell and the -returned value will be used. In the rare case where none of these methods -work or an exception is raised the function will simply return 1.

- - - (Integer) processor_count - - - - - -

-
-

Number of processors seen by the OS and used for process scheduling. For -performance reasons the calculated value will be memoized on the first -call.

- -

When running under JRuby the Java runtime call -java.lang.Runtime.getRuntime.availableProcessors will be used. According -to the Java documentation this "value may change during a particular -invocation of the virtual machine... [applications] should therefore -occasionally poll this property." Subsequently the result will NOT be -memoized under JRuby.

- -

On Windows the Win32 API will be queried for the -NumberOfLogicalProcessors from Win32_Processor. This will return the -total number "logical processors for the current instance of the -processor", which taked into account hyperthreading.

Overview

-
- -
- Note: -

Failure to properly shutdown a thread pool can lead to unpredictable results. -Please read Shutting Down Thread Pools for more information.

-
-
- -
- Note: -

When running on the JVM (JRuby) this class will inherit from JavaThreadPoolExecutor. -On all other platforms it will inherit from RubyThreadPoolExecutor.

-
-
- -

A thread pool that dynamically grows and shrinks to fit the current workload. -New threads are created as needed, existing threads are reused, and threads -that remain idle for too long are killed and removed from the pool. These -pools are particularly suited to applications that perform a high volume of -short-lived tasks.

- -

On creation a CachedThreadPool has zero running threads. New threads are -created on the pool as new operations are #post. The size of the pool -will grow until #max_length threads are in the pool or until the number -of threads exceeds the number of running and pending operations. When a new -operation is post to the pool the first available idle thread will be tasked -with the new operation.

- -

Should a thread crash for any reason the thread will immediately be removed -from the pool. Similarly, threads which remain idle for an extended period -of time will be killed and reclaimed. Thus these thread pools are very -efficient at reclaiming unused resources.

- -

The API and behavior of this class are based on Java's CachedThreadPool

- -

Thread pools support several configuration options:

- -
    -
  • idletime: The number of seconds that a thread may be idle before being reclaimed.
    • -
  • max_queue: The maximum number of tasks that may be waiting in the work queue at -any one time. When the queue size reaches max_queue subsequent tasks will be -rejected in accordance with the configured fallback_policy.
    • -
  • stop_on_exit: When true (default) an at_exit handler will be registered which -will stop the thread pool when the application exits. See below for more information -on shutting down thread pools.
    • -
  • fallback_policy: The policy defining how rejected tasks are handled.
    • -
- -

Three fallback policies are supported:

- -
    -
  • :abort: Raise a RejectedExecutionError exception and discard the task.
    • -
  • :discard: Discard the task and return false.
    • -
  • :caller_runs: Execute the task on the calling thread.
    • -
- -

Shutting Down Thread Pools

- -

Killing a thread pool while tasks are still being processed, either by calling -the #kill method or at application exit, will have unpredictable results. There -is no way for the thread pool to know what resources are being used by the -in-progress tasks. When those tasks are killed the impact on those resources -cannot be predicted. The best practice is to explicitly shutdown all thread -pools using the provided methods:

- -
    -
  • Call #shutdown to initiate an orderly termination of all in-progress tasks
    • -
  • Call #wait_for_termination with an appropriate timeout interval an allow -the orderly shutdown to complete
    • -
  • Call #kill only when the thread pool fails to shutdown in the allotted time
    • -
- -

On some runtime platforms (most notably the JVM) the application will not -exit until all thread pools have been shutdown. To prevent applications from -"hanging" on exit all thread pools include an at_exit handler that will -stop the thread pool when the application exists. This handler uses a brute -force method to stop the pool and makes no guarantees regarding resources being -used by any tasks still running. Registration of this at_exit handler can be -prevented by setting the thread pool's constructor :stop_on_exit option to -false when the thread pool is created. All thread pools support this option.

- -
pool1 = Concurrent::FixedThreadPool.new(5) # an `at_exit` handler will be registered
-pool2 = Concurrent::FixedThreadPool.new(5, stop_on_exit: false) # prevent `at_exit` handler registration

Overview

-
- -
- Note: -

Failure to properly shutdown a thread pool can lead to unpredictable results. -Please read Shutting Down Thread Pools for more information.

-
-
- -
- Note: -

When running on the JVM (JRuby) this class will inherit from JavaThreadPoolExecutor. -On all other platforms it will inherit from RubyThreadPoolExecutor.

-
-
- -

A thread pool with a set number of threads. The number of threads in the pool -is set on construction and remains constant. When all threads are busy new -tasks #post to the thread pool are enqueued until a thread becomes available. -Should a thread crash for any reason the thread will immediately be removed -from the pool and replaced.

- -

The API and behavior of this class are based on Java's FixedThreadPool

- -

Thread pools support several configuration options:

- -
    -
  • idletime: The number of seconds that a thread may be idle before being reclaimed.
    • -
  • max_queue: The maximum number of tasks that may be waiting in the work queue at -any one time. When the queue size reaches max_queue subsequent tasks will be -rejected in accordance with the configured fallback_policy.
    • -
  • stop_on_exit: When true (default) an at_exit handler will be registered which -will stop the thread pool when the application exits. See below for more information -on shutting down thread pools.
    • -
  • fallback_policy: The policy defining how rejected tasks are handled.
    • -
- -

Three fallback policies are supported:

- -
    -
  • :abort: Raise a RejectedExecutionError exception and discard the task.
    • -
  • :discard: Discard the task and return false.
    • -
  • :caller_runs: Execute the task on the calling thread.
    • -
- -

Shutting Down Thread Pools

- -

Killing a thread pool while tasks are still being processed, either by calling -the #kill method or at application exit, will have unpredictable results. There -is no way for the thread pool to know what resources are being used by the -in-progress tasks. When those tasks are killed the impact on those resources -cannot be predicted. The best practice is to explicitly shutdown all thread -pools using the provided methods:

- -
    -
  • Call #shutdown to initiate an orderly termination of all in-progress tasks
    • -
  • Call #wait_for_termination with an appropriate timeout interval an allow -the orderly shutdown to complete
    • -
  • Call #kill only when the thread pool fails to shutdown in the allotted time

On some runtime platforms (most notably the JVM) the application will not -exit until all thread pools have been shutdown. To prevent applications from -"hanging" on exit all thread pools include an at_exit handler that will -stop the thread pool when the application exists. This handler uses a brute -force method to stop the pool and makes no guarantees regarding resources being -used by any tasks still running. Registration of this at_exit handler can be -prevented by setting the thread pool's constructor :stop_on_exit option to -false when the thread pool is created. All thread pools support this option.

- -
pool1 = Concurrent::FixedThreadPool.new(5) # an `at_exit` handler will be registered
-pool2 = Concurrent::FixedThreadPool.new(5, stop_on_exit: false) # prevent `at_exit` handler registration

Overview

-
- -
- Note: -

Failure to properly shutdown a thread pool can lead to unpredictable results. -Please read Shutting Down Thread Pools for more information.

-
-
- -
- Note: -

When running on the JVM (JRuby) this class will inherit from JavaThreadPoolExecutor. -On all other platforms it will inherit from RubyThreadPoolExecutor.

-
-
- -

A thread pool with a set number of threads. The number of threads in the pool -is set on construction and remains constant. When all threads are busy new -tasks #post to the thread pool are enqueued until a thread becomes available. -Should a thread crash for any reason the thread will immediately be removed -from the pool and replaced.

- -

The API and behavior of this class are based on Java's SingleThreadExecutor

- -

Thread pools support several configuration options:

- -
    -
  • idletime: The number of seconds that a thread may be idle before being reclaimed.
    • -
  • max_queue: The maximum number of tasks that may be waiting in the work queue at -any one time. When the queue size reaches max_queue subsequent tasks will be -rejected in accordance with the configured fallback_policy.
    • -
  • stop_on_exit: When true (default) an at_exit handler will be registered which -will stop the thread pool when the application exits. See below for more information -on shutting down thread pools.
    • -
  • fallback_policy: The policy defining how rejected tasks are handled.
    • -
- -

Three fallback policies are supported:

- -
    -
  • :abort: Raise a RejectedExecutionError exception and discard the task.
    • -
  • :discard: Discard the task and return false.
    • -
  • :caller_runs: Execute the task on the calling thread.
    • -
- -

Shutting Down Thread Pools

- -

Killing a thread pool while tasks are still being processed, either by calling -the #kill method or at application exit, will have unpredictable results. There -is no way for the thread pool to know what resources are being used by the -in-progress tasks. When those tasks are killed the impact on those resources -cannot be predicted. The best practice is to explicitly shutdown all thread -pools using the provided methods:

- -
    -
  • Call #shutdown to initiate an orderly termination of all in-progress tasks
    • -
  • Call #wait_for_termination with an appropriate timeout interval an allow -the orderly shutdown to complete
    • -
  • Call #kill only when the thread pool fails to shutdown in the allotted time
    • -
- -

On some runtime platforms (most notably the JVM) the application will not -exit until all thread pools have been shutdown. To prevent applications from -"hanging" on exit all thread pools include an at_exit handler that will -stop the thread pool when the application exists. This handler uses a brute -force method to stop the pool and makes no guarantees regarding resources being -used by any tasks still running. Registration of this at_exit handler can be -prevented by setting the thread pool's constructor :stop_on_exit option to -false when the thread pool is created. All thread pools support this option.

pool1 = Concurrent::FixedThreadPool.new(5) # an `at_exit` handler will be registered

Overview

-
- -
- Note: -

Failure to properly shutdown a thread pool can lead to unpredictable results. -Please read Shutting Down Thread Pools for more information.

-
-
- -
- Note: -

When running on the JVM (JRuby) this class will inherit from JavaThreadPoolExecutor. -On all other platforms it will inherit from RubyThreadPoolExecutor.

-
-
- -

An abstraction composed of one or more threads and a task queue. Tasks -(blocks or proc objects) are submit to the pool and added to the queue. -The threads in the pool remove the tasks and execute them in the order -they were received. When there are more tasks queued than there are -threads to execute them the pool will create new threads, up to the -configured maximum. Similarly, threads that are idle for too long will -be garbage collected, down to the configured minimum options. Should a -thread crash it, too, will be garbage collected.

- -

ThreadPoolExecutor is based on the Java class of the same name. From -the official Java documentationa;

- -
-

Thread pools address two different problems: they usually provide -improved performance when executing large numbers of asynchronous tasks, -due to reduced per-task invocation overhead, and they provide a means -of bounding and managing the resources, including threads, consumed -when executing a collection of tasks. Each ThreadPoolExecutor also -maintains some basic statistics, such as the number of completed tasks.

- -

To be useful across a wide range of contexts, this class provides many -adjustable parameters and extensibility hooks. However, programmers are -urged to use the more convenient Executors factory methods -CachedThreadPool, -FixedThreadPool and SingleThreadExecutor, that preconfigure settings for the most common usage -scenarios.

-
- -

Thread pools support several configuration options:

- -
    -
  • idletime: The number of seconds that a thread may be idle before being reclaimed.
    • -
  • max_queue: The maximum number of tasks that may be waiting in the work queue at -any one time. When the queue size reaches max_queue subsequent tasks will be -rejected in accordance with the configured fallback_policy.
    • -
  • stop_on_exit: When true (default) an at_exit handler will be registered which -will stop the thread pool when the application exits. See below for more information -on shutting down thread pools.
    • -
  • fallback_policy: The policy defining how rejected tasks are handled.
    • -
- -

Three fallback policies are supported:

- -
    -
  • :abort: Raise a RejectedExecutionError exception and discard the task.
    • -
  • :discard: Discard the task and return false.
    • -
  • :caller_runs: Execute the task on the calling thread.
    • -
- -

Shutting Down Thread Pools

- -

Killing a thread pool while tasks are still being processed, either by calling -the #kill method or at application exit, will have unpredictable results. There -is no way for the thread pool to know what resources are being used by the -in-progress tasks. When those tasks are killed the impact on those resources -cannot be predicted. The best practice is to explicitly shutdown all thread -pools using the provided methods:

- -
    -
  • Call #shutdown to initiate an orderly termination of all in-progress tasks
    • -
  • Call #wait_for_termination with an appropriate timeout interval an allow -the orderly shutdown to complete
    • -
  • Call #kill only when the thread pool fails to shutdown in the allotted time
    • -

On some runtime platforms (most notably the JVM) the application will not -exit until all thread pools have been shutdown. To prevent applications from -"hanging" on exit all thread pools include an at_exit handler that will -stop the thread pool when the application exists. This handler uses a brute -force method to stop the pool and makes no guarantees regarding resources being -used by any tasks still running. Registration of this at_exit handler can be -prevented by setting the thread pool's constructor :stop_on_exit option to -false when the thread pool is created. All thread pools support this option.

- -
pool1 = Concurrent::FixedThreadPool.new(5) # an `at_exit` handler will be registered
-pool2 = Concurrent::FixedThreadPool.new(5, stop_on_exit: false) # prevent `at_exit` handler registration

- - - -
Defined in:

Overview

-
-

Indicates that the including Executor or ExecutorService guarantees -that all operations will occur in the order they are post and that no -two operations may occur simultaneously. This module provides no -functionality and provides no guarantees. That is the responsibility -of the including class. This module exists solely to allow the including -object to be interrogated for its serialization status.

- - -
-
-
- -
-

Examples:

- - - 
class Foo
-  include Concurrent::SerialExecutor
-end
-
-foo = Foo.new
-
-foo.is_a? Concurrent::Executor       #=> true
-foo.is_a? Concurrent::SerialExecutor #=> true
-foo.serialized?                      #=> true

Agents are inspired by Clojure's agent function. An Agent is a single atomic value that represents an identity. The current value of the Agent can be requested at any time (deref). Each Agent has a work queue and operates on the global thread pool (see below). Consumers can post code blocks to the Agent. The code block (function) will receive the current value of the Agent as its sole parameter. The return value of the block will become the new value of the Agent. Agents support two error handling modes: fail and continue. A good example of an Agent is a shared incrementing counter, such as the score in a video game.

- -

An Agent must be initialize with an initial value. This value is always accessible via the value (or deref) methods. Code blocks sent to the Agent will be processed in the order received. As each block is processed the current value is updated with the result from the block. This update is an atomic operation so a deref will never block and will always return the current value.

- -

When an Agent is created it may be given an optional validate block and zero or more rescue blocks. When a new value is calculated the value will be checked against the validator, if present. If the validator returns true the new value will be accepted. If it returns false it will be rejected. If a block raises an exception during execution the list of rescue blocks will be seacrhed in order until one matching the current exception is found. That rescue block will then be called an passed the exception object. If no matching rescue block is found, or none were configured, then the exception will be suppressed.

- -

Agents also implement Ruby's Observable. Code that observes an Agent will receive a callback with the new value any time the value is changed.

- -

Copy Options

- -

Object references in Ruby are mutable. This can lead to serious problems when the value of an Agent is a mutable reference. Which is always the case unless the value is a Fixnum, Symbol, or similar "primative" data type. Each Agent instance can be configured with a few options that can help protect the program from potentially dangerous operations. Each of these options can be optionally set when the Agent is created:

- -
    -
  • :dup_on_deref when true the Agent will call the #dup method on the value object every time the #value methid is called (default: false)
    • -
  • :freeze_on_deref when true the Agent will call the #freeze method on the value object every time the #value method is called (default: false)
    • -
  • :copy_on_deref when given a Proc object the Proc will be run every time the #value method is called. The Proc will be given the current value as its only parameter and the result returned by the block will be the return value of the #value call. When nil this option will be ignored (default: nil)
    • -
- -

Examples

- -

A simple example:

- -
require 'concurrent'
-
-score = Concurrent::Agent.new(10)
-score.value #=> 10
-
-score << proc{|current| current + 100 }
-sleep(0.1)
-score.value #=> 110
-
-score << proc{|current| current * 2 }
-sleep(0.1)

A mixin module that provides simple asynchronous behavior to any standard -class/object or object.

- -
Feature:
-  As a stateful, plain old Ruby class/object
-  I want safe, asynchronous behavior
-  So my long-running methods don't block the main thread
-
- -

Stateful, mutable objects must be managed carefully when used asynchronously. -But Ruby is an object-oriented language so designing with objects and classes -plays to Ruby's strengths and is often more natural to many Ruby programmers. -The Async module is a way to mix simple yet powerful asynchronous capabilities -into any plain old Ruby object or class. These capabilities provide a reasonable -level of thread safe guarantees when used correctly.

- -

When this module is mixed into a class or object it provides to new methods: -async and await. These methods are thread safe with respect to the enclosing -object. The former method allows methods to be called asynchronously by posting -to the global thread pool. The latter allows a method to be called synchronously -on the current thread but does so safely with respect to any pending asynchronous -method calls. Both methods return an Obligation which can be inspected for -the result of the method call. Calling a method with async will return a -:pending Obligation whereas await will return a :complete Obligation.

- -

Very loosely based on the async and await keywords in C#.

- -

An Important Note About Initialization

- -
-

This module depends on several internal synchronization objects that -must be initialized prior to calling any of the async/await/executor methods. -The best practice is to call init_mutex from within the constructor -of the including class. A less ideal but acceptable practice is for the -thread creating the asynchronous object to explicitly call the init_mutex -method prior to calling any of the async/await/executor methods. If -init_mutex is not called explicitly the async/await/executor methods -will raise a Concurrent::InitializationError. This is the only way -thread-safe initialization can be guaranteed.

-
- -

An Important Note About Thread Safe Guarantees

- -
-

Thread safe guarantees can only be made when asynchronous method calls -are not mixed with synchronous method calls. Use only synchronous calls -when the object is used exclusively on a single thread. Use only -async and await when the object is shared between threads. Once you -call a method using async, you should no longer call any methods -directly on the object. Use async and await exclusively from then on. -With careful programming it is possible to switch back and forth but it's -also very easy to create race conditions and break your application. -Basically, it's "async all the way down."

Examples

Defining an asynchronous class

- -
Scenario: Defining an asynchronous class
-  Given a class definition
-  When I include the Concurrent::Async module
-  Then an `async` method is defined for all objects of the class
-  And an `await` method is defined for all objects of the class
-
-Scenario: Calling the `async` method
-  Given a class which includes Concurrent::Async module
-  When I call a normal method through the `async` delegate method
-  Then the method returns a Concurrent::Future object
-  And the method is executed on a background thread using the global thread pool
-  And the current thread does not block
-  And thread safety is provided with respect to other `async` and `await` calls
-  And the returned future can be interrogated for the status of the method call
-  And the returned future will eventually contain the `value` of the method call
-  Or the returned future will eventually contain the `reason` the method call failed
-
-Scenario: Calling the `await` method
-  Given a class which includes Concurrent::Async module
-  When I call a normal method through the `await` delegate method
-  Then the method returns a Concurrent::IVar object
-  And the method is executed on the current thread
-  And thread safety is provided with respect to other `async` and `await` calls
-  And the returned ivar will be in the :fulfilled state
-  Or the returned ivar will be in the :rejected state
-  And the returned ivar will immediately contain the `value` of the method call
-  Or the returned ivar will immediately contain the `reason` the method call failed
-
- -
class Echo
-  include Concurrent::Async
-
-  def initialize
-    init_mutex # initialize the internal synchronization objects
-  end
-
-  def echo(msg)
-    sleep(rand)
-    print "#{msg}\n"
-    nil
-  end
-end
-
-horn = Echo.new
-horn.echo('zero') # synchronous, not thread-safe
-
-horn.async.echo('one') # asynchronous, non-blocking, thread-safe
-horn.await.echo('two') # synchronous, blocking, thread-safe

Monkey-patching an existing object

- -
Scenario: Monkey-patching an existing object
-  Given an object of a class that does not include the Concurrent::Async module
-  When I extend the object with the Concurrent::Async module
-  Then an `async` method is monkey-patched onto the object
-  And an `await` method is monkey-patched onto the object
-  And the object behaved as though Concurrent::Async were included in the class
-  And the `async` and `await` methods perform as expected
-  And no other objects of that class are affected
-
- -
numbers = 1_000_000.times.collect{ rand }
-numbers.extend(Concurrent::Async)
-numbers.init_mutex # initialize the internal synchronization objects

Dataflow allows you to create a task that will be scheduled when all of its data dependencies are available. Data dependencies are Future values. The dataflow task itself is also a Future value, so you can build up a graph of these tasks, each of which is run when all the data and other tasks it depends on are available or completed.

- -

Our syntax is somewhat related to that of Akka's flow and Habanero Java's DataDrivenFuture. However unlike Akka we don't schedule a task at all until it is ready to run, and unlike Habanero Java we pass the data values into the task instead of dereferencing them again in the task.

- -

The theory of dataflow goes back to the 70s. In the terminology of the literature, our implementation is coarse-grained, in that each task can be many instructions, and dynamic in that you can create more tasks within other tasks.

- -

Example

- -

A dataflow task is created with the dataflow method, passing in a block.

- -
task = Concurrent::dataflow { 14 }
-
- -

This produces a simple Future value. The task will run immediately, as it has no dependencies. We can also specify Future values that must be available before a task will run. When we do this we get the value of those futures passed to our block.

- -
a = Concurrent::dataflow { 1 }
-b = Concurrent::dataflow { 2 }
-c = Concurrent::dataflow(a, b) { |av, bv| av + bv }
-
- -

Using the dataflow method you can build up a directed acyclic graph (DAG) of tasks that depend on each other, and have the tasks run as soon as their dependencies are ready and there is CPU capacity to schedule them. This can help you create a program that uses more of the CPU resources available to you.

- -

Derivation

- -

This section describes how we could derive dataflow from other primitives in this library.

- -

Consider a naive fibonacci calculator.

- -
def fib(n)
-  if n < 2
-    n
-  else
-    fib(n - 1) + fib(n - 2)
-  end
-end
-
-puts fib(14) #=> 377
-
- -

We could modify this to use futures.

- -
def fib(n)
-  if n < 2
-    Concurrent::Future.new { n }
-  else
-    n1 = fib(n - 1).execute
-    n2 = fib(n - 2).execute
-    Concurrent::Future.new { n1.value + n2.value }
-  end
-end
-
-f = fib(14) #=> #<Concurrent::Future:0x000001019ef5a0 ...
-f.execute   #=> #<Concurrent::Future:0x000001019ef5a0 ...
-
-sleep(0.5)
-
-puts f.value #=> 377
-
- -

One of the drawbacks of this approach is that all the futures start, and then most of them immediately block on their dependencies. We know that there's no point executing those futures until their dependencies are ready, so let's not execute each future until all their dependencies are ready.

- -

To do this we'll create an object that counts the number of times it observes a future finishing before it does something - and for us that something will be to execute the next future.

- -
class CountingObserver
-
-  def initialize(count, &block)
-    @count = count
-    @block = block
-  end
-
-  def update(time, value, reason)
-    @count -= 1
-
-    if @count <= 0
-      @block.call()
-    end
-  end
-
-end
-
-def fib(n)
-  if n < 2
-    Concurrent::Future.new { n }.execute
-  else
-    n1 = fib(n - 1)
-    n2 = fib(n - 2)
-
-    result = Concurrent::Future.new { n1.value + n2.value }
-
-    barrier = CountingObserver.new(2) { result.execute }
-    n1.add_observer barrier
-    n2.add_observer barrier
-
-    n1.execute
-    n2.execute
-
-    result
-  end
-end
-
- -

We can wrap this up in a dataflow utility.

- -
f = fib(14) #=> #<Concurrent::Future:0x00000101fca308 ...
-sleep(0.5)
-
-puts f.value #=> 377
-
-def dataflow(*inputs, &block)
-  result = Concurrent::Future.new(&block)
-
-  if inputs.empty?
-    result.execute
-  else
-    barrier = CountingObserver.new(inputs.size) { result.execute }
-
-    inputs.each do |input|
-      input.add_observer barrier
-    end
-  end
-
-  result
-end
-
-def fib(n)
-  if n < 2
-    dataflow { n }
-  else
-    n1 = fib(n - 1)
-    n2 = fib(n - 2)
-    dataflow(n1, n2) { n1.value + n2.value }
-  end
-end
-
-f = fib(14) #=> #<Concurrent::Future:0x00000101fca308 ...
-sleep(0.5)
-
-puts f.value #=> 377
-
- -

Since we know that the futures the dataflow computation depends on are already going to be available when the future is executed, we might as well pass the values into the block so we don't have to reference the futures inside the block. This allows us to write the dataflow block as straight non-concurrent code without reference to futures.

- -
def dataflow(*inputs, &block)
-  result = Concurrent::Future.new do
-    values = inputs.map { |input| input.value }
-    block.call(*values)
-  end
-
-  if inputs.empty?
-    result.execute
-  else
-    barrier = CountingObserver.new(inputs.size) { result.execute }
-
-    inputs.each do |input|
-      input.add_observer barrier
-    end
-  end
-
-  result
-end
-
-def fib(n)
-  if n < 2
-    Concurrent::dataflow { n }
-  else
-    n1 = fib(n - 1)
-    n2 = fib(n - 2)
-    Concurrent::dataflow(n1, n2) { |v1, v2| v1 + v2 }
-  end

Future is inspired by Clojure's future function. A future represents a promise to complete an action at some time in the future. The action is atomic and permanent. The idea behind a future is to send an operation for asynchronous completion, do other stuff, then return and retrieve the result of the async operation at a later time. Futures run on the global thread pool.

- -
Feature:
-  As a highly responsive Ruby application
-  I want long-running tasks on a separate thread
-  So I can perform other tasks without waiting
-
- -

Futures have four possible states: :unscheduled, :pending, :rejected, and :fulfilled. When a Future is created it is set to :unscheduled. Once the #execute method is called the state becomes :pending and will remain in that state until processing is complete. A completed Future is either :rejected, indicating that an exception was thrown during processing, or :fulfilled, indicating success. If a Future is :fulfilled its #value will be updated to reflect the result of the operation. If :rejected the reason will be updated with a reference to the thrown exception. The predicate methods #unscheduled?, #pending?, #rejected?, and #fulfilled? can be called at any time to obtain the state of the Future, as can the #state method, which returns a symbol.

- -

Retrieving the value of a Future is done through the #value (alias: #deref) method. Obtaining the value of a Future is a potentially blocking operation. When a Future is :rejected a call to #value will return nil immediately. When a Future is :fulfilled a call to #value will immediately return the current value. When a Future is :pending a call to #value will block until the Future is either :rejected or :fulfilled. A timeout value can be passed to #value to limit how long the call will block. If nil the call will block indefinitely. If 0 the call will not block. Any other integer or float value will indicate the maximum number of seconds to block.

- -

The constructor can also be given zero or more processing options. Currently the only supported options are those recognized by the Dereferenceable module.

- -

The Future class also includes the behavior of the Ruby standard library Observable module, but does so in a thread-safe way. On fulfillment or rejection all observers will be notified according to the normal Observable behavior. The observer callback function will be called with three parameters: the Time of fulfillment/rejection, the final value, and the final reason. Observers added after fulfillment/rejection will still be notified as normal. The notification will occur on the global thread pool.

- -

Examples

- -

A fulfilled example:

- -
require 'concurrent'
-require 'thread'   # for Queue
-require 'open-uri' # for open(uri)
-
-class Ticker
-  def get_year_end_closing(symbol, year)
-    uri = "http://ichart.finance.yahoo.com/table.csv?s=#{symbol}&a=11&b=01&c=#{year}&d=11&e=31&f=#{year}&g=m"
-    data = open(uri) {|f| f.collect{|line| line.strip } }
-    data[1].split(',')[4].to_f
-  end
-end
-
-# Future
-price = Concurrent::Future.execute{ Ticker.new.get_year_end_closing('TWTR', 2013) }
-price.state #=> :pending
-price.pending? #=> true
-price.value(0) #=> nil (does not block)
-
-sleep(1)    # do other stuff
-
-price.value #=> 63.65 (after blocking if neccesary)
-price.state #=> :fulfilled
-price.fulfilled? #=> true
-price.value #=> 63.65
-
- -

A rejected example:

- -
count = Concurrent::Future.execute{ sleep(10); raise StandardError.new("Boom!") }
-count.state #=> :pending
-count.pending? #=> true
-
-count.value #=> nil (after blocking)
-count.rejected? #=> true
-count.reason #=> #<StandardError: Boom!> 
-

Promises are inspired by the JavaScript Promises/A and Promises/A+ specifications.

- -
-

A promise represents the eventual value returned from the single completion of an operation.

-
- -

Promises are similar to futures and share many of the same behaviours. Promises are far more robust, however. Promises can be chained in a tree structure where each promise may have zero or more children. Promises are chained using the then method. The result of a call to then is always another promise. Promises are resolved asynchronously (with respect to the main thread) but in a strict order: parents are guaranteed to be resolved before their children, children before their younger siblings. The then method takes two parameters: an optional block to be executed upon parent resolution and an optional callable to be executed upon parent failure. The result of each promise is passed to each of its children upon resolution. When a promise is rejected all its children will be summarily rejected and will receive the reason.

- -

Promises have four possible states: unscheduled, pending, rejected, and fulfilled. A Promise created using .new will be unscheduled. It is scheduled by calling the execute method. Upon execution the Promise and all its children will be set to pending. When a promise is pending it will remain in that state until processing is complete. A completed Promise is either rejected, indicating that an exception was thrown during processing, or fulfilled, indicating it succeeded. If a Promise is fulfilled its value will be updated to reflect the result of the operation. If rejected the reason will be updated with a reference to the thrown exception. The predicate methods unscheduled?, pending?, rejected?, and fulfilled? can be called at any time to obtain the state of the Promise, as can the state method, which returns a symbol. A Promise created using .execute will be pending, a Promise created using .fulfill(value) will be fulfilled with the given value and a Promise created using .reject(reason) will be rejected with the given reason.

- -

Retrieving the value of a promise is done through the value (alias: deref) method. Obtaining the value of a promise is a potentially blocking operation. When a promise is rejected a call to value will return nil immediately. When a promise is fulfilled a call to value will immediately return the current value. When a promise is pending a call to value will block until the promise is either rejected or fulfilled. A timeout value can be passed to value to limit how long the call will block. If nil the call will block indefinitely. If 0 the call will not block. Any other integer or float value will indicate the maximum number of seconds to block.

- -

Promises run on the global thread pool.

- -

Examples

- -

Start by requiring promises

- -
require 'concurrent'
-
- -

Then create one

- -
p = Promise.execute do
-      # do something
-      42
-    end
-
- -

Promises can be chained using the then method. The then method accepts a block, to be executed on fulfillment, and a callable argument to be executed on rejection. The result of the each promise is passed as the block argument to chained promises.

- -
p = Concurrent::Promise.new{10}.then{|x| x * 2}.then{|result| result - 10 }.execute
-
- -

And so on, and so on, and so on...

- -
p = Concurrent::Promise.fulfill(20).
-    then{|result| result - 10 }.
-    then{|result| result * 3 }.
-    then{|result| result % 5 }.execute
-
- -

The initial state of a newly created Promise depends on the state of its parent:

- -
    -
  • if parent is unscheduled the child will be unscheduled
    • -
  • if parent is pending the child will be pending
    • -
  • if parent is fulfilled the child will be pending
    • -
  • if parent is rejected the child will be pending (but will ultimately be rejected)
    • -
- -

Promises are executed asynchronously from the main thread. By the time a child Promise finishes initialization it may be in a different state that its parent (by the time a child is created its parent may have completed execution and changed state). Despite being asynchronous, however, the order of execution of Promise objects in a chain (or tree) is strictly defined.

- -

There are multiple ways to create and execute a new Promise. Both ways provide identical behavior:

- -
# create, operate, then execute
-p1 = Concurrent::Promise.new{ "Hello World!" }
-p1.state #=> :unscheduled
-p1.execute
-
-# create and immediately execute
-p2 = Concurrent::Promise.new{ "Hello World!" }.execute
-
-# execute during creation
-p3 = Concurrent::Promise.execute{ "Hello World!" }
-
- -

Once the execute method is called a Promise becomes pending:

- -
p = Concurrent::Promise.execute{ "Hello, world!" }
-p.state    #=> :pending
-p.pending? #=> true
-
- -

Wait a little bit, and the promise will resolve and provide a value:

- -
p = Concurrent::Promise.execute{ "Hello, world!" }
-sleep(0.1)
-
-p.state      #=> :fulfilled
-p.fulfilled? #=> true
-p.value      #=> "Hello, world!"
-
- -

If an exception occurs, the promise will be rejected and will provide -a reason for the rejection:

- -
p = Concurrent::Promise.execute{ raise StandardError.new("Here comes the Boom!") }
-sleep(0.1)
-
-p.state     #=> :rejected
-p.rejected? #=> true
-p.reason    #=> "#<StandardError: Here comes the Boom!>"
-
- -

Rejection

- -

When a promise is rejected all its children will be rejected and will receive the rejection reason as the rejection callable parameter:

- -
p = [ Concurrent::Promise.execute{ Thread.pass; raise StandardError } ]
-
-c1 = p.then(Proc.new{ |reason| 42 })
-c2 = p.then(Proc.new{ |reason| raise 'Boom!' })
-
-sleep(0.1)
-
-c1.state  #=> :rejected
-c2.state  #=> :rejected
-
- -

Once a promise is rejected it will continue to accept children that will receive immediately rejection (they will be executed asynchronously).

- -

Aliases

- -

The then method is the most generic alias: it accepts a block to be executed upon parent fulfillment and a callable to be executed upon parent rejection. At least one of them should be passed. The default block is { |result| result } that fulfills the child with the parent value. The default callable is { |reason| raise reason } that rejects the child with the parent reason.

- -
    -
  • on_success { |result| ... } is the same as then {|result| ... }
    • -
  • rescue { |reason| ... } is the same as then(Proc.new { |reason| ... } )
    • -
  • rescue is aliased by catch and on_error

ScheduledTask is a close relative of Concurrent::Future but with one important difference. A Future is set to execute as soon as possible whereas a ScheduledTask is set to execute at a specific time. This implementation is loosely based on Java's ScheduledExecutorService. 

-
-
Example

-
-
require 'concurrent'
-require 'thread'   # for Queue
-require 'open-uri' # for open(uri)
-
-class Ticker
-  def get_year_end_closing(symbol, year)
-    uri = "http://ichart.finance.yahoo.com/table.csv?s=#{symbol}&a=11&b=01&c=#{year}&d=11&e=31&f=#{year}&g=m"
-    data = open(uri) {|f| f.collect{|line| line.strip } }
-    data[1].split(',')[4].to_f
-  end
-end
-
-# Future
-price = Concurrent::Future.execute{ Ticker.new.get_year_end_closing('TWTR', 2013) }
-price.state #=> :pending
-sleep(1)    # do other stuff
-price.value #=> 63.65
-price.state #=> :fulfilled
-
-# ScheduledTask
-task = Concurrent::ScheduledTask.execute(2){ Ticker.new.get_year_end_closing('INTC', 2013) }
-task.state #=> :pending
-sleep(3)   # do other stuff
-task.value #=> 25.96
-

-
-
Scheduling

-
-
The intended schedule time of task execution is set on object construction with first argument. The time can be a numeric (floating point or integer) representing a number of seconds in the future or it can ba a Time object representing the approximate time of execution. Any other value, a numeric equal to or less than zero, or a time in the past will result in an exception. 

-
-
The actual schedule time of task execution is set when the execute method is called. If the intended schedule time was given as a number of seconds then the actual schedule time will be calculated from the current time. If the intended schedule time was given as a Time object the current time will be checked against the intended schedule time. If the intended schedule time is now in the past an exception will be raised. 

-
-
The constructor can also be given zero or more processing options. Currently the only supported options are those recognized by the Dereferenceable module. 

-
-
The final constructor argument is a block representing the task to be performed at the scheduled time. If no block is given an ArgumentError will be raised.

-
-
States

-
-
ScheduledTask mixes in the  Obligation module thus giving it "future" behavior. This includes the expected lifecycle states. ScheduledTask has one additional state, however. While the task (block) is being executed the state of the object will be :in_progress. This additional state is  necessary because it has implications for task cancellation. 

-
-
Cancellation

-
-
A :pending task can be cancelled using the #cancel method. A task in any other state, including :in_progress, cannot be cancelled. The #cancel method returns a boolean indicating the success of the cancellation attempt. A cancelled ScheduledTask cannot be restarted. It is immutable. 

-
-
Obligation and Observation

-
-
The result of a ScheduledTask can be obtained either synchronously or asynchronously. ScheduledTask mixes in both the Obligation module and the Observable module from the Ruby standard library. With one exception ScheduledTask behaves identically to Future with regard to these modules. 

-
-
Unlike Future, however, an observer added to a ScheduledTask after the task operation has completed will not receive notification. The reason for this is the subtle but important difference in intent between the two abstractions. With a Future there is no way to know when the operation will complete. Therefore the expected behavior of an observer is to be notified. With a ScheduledTask however, the approximate time of execution is known. It is often explicitly set as a constructor argument. It is always available via the #schedule_time attribute reader. Therefore it is always possible for calling code to know whether the observer is being added prior to task execution. It is also easy to add an observer long before task execution begins (since there is never a reason to create a scheduled task that starts immediately). Subsequently, the expectation is that the caller of #add_observer is making the call within an appropriate time. 

-
-
Examples

-
-
Successful task execution using seconds for scheduling:

-
-
require 'concurrent'
-
-task = Concurrent::ScheduledTask.new(2){ 'What does the fox say?' }
-task.state         #=> :unscheduled
-task.schedule_time #=> nil
-task.execute
-task.state         #=> pending
-task.schedule_time #=> 2013-11-07 12:20:07 -0500
-
-# wait for it...
-sleep(3)
-
-task.unscheduled? #=> false
-task.pending?     #=> false
-task.fulfilled?   #=> true
-task.rejected?    #=> false
-task.value        #=> 'What does the fox say?'
-

-
-
A ScheduledTask can be created and executed in one line:

-
-
task = Concurrent::ScheduledTask.new(2){ 'What does the fox say?' }.execute
-task.state         #=> pending
-task.schedule_time #=> 2013-11-07 12:20:07 -0500
-

-
-
Failed task execution using a Time object for scheduling:

-
-
t = Time.now + 2
-task = Concurrent::ScheduledTask.execute(t){ raise StandardError.new('Call me maybe?') }
-task.pending?      #=> true
-task.schedule_time #=> 2013-11-07 12:22:01 -0500
-
-# wait for it...
-sleep(3)
-
-task.unscheduled? #=> false
-task.pending?     #=> false
-task.fulfilled?   #=> false
-task.rejected?    #=> true
-task.value        #=> nil
-task.reason       #=> #<StandardError: Call me maybe?> 
-

-
-
An exception will be thrown on creation if the schedule time is in the past:

-
-
task = Concurrent::ScheduledTask.new(Time.now - 10){ nil }
-  #=> ArgumentError: schedule time must be in the future
-
-task = Concurrent::ScheduledTask.execute(-10){ nil }
-  #=> ArgumentError: seconds must be greater than zero
-

-
-
An exception will also be thrown when #execute is called if the current time has
-progressed past the intended schedule time:

-
-
task = Concurrent::ScheduledTask.new(Time.now + 10){ nil }
-sleep(20)
-
-task.execute
-  #=> ArgumentError: schedule time must be in the future
-

-
-
Task execution with observation:

-
-
observer = Class.new{
-  def update(time, value, reason)
-    puts "The task completed at #{time} with value '#{value}'"
-  end
-}.new
-
-task = Concurrent::ScheduledTask.new(2){ 'What does the fox say?' }
-task.add_observer(observer)
-task.execute
-task.pending?      #=> true
-task.schedule_time #=> 2013-11-07 12:20:07 -0500
-
-# wait for it...
-sleep(3)
-
-#>> The task completed at 2013-11-07 12:26:09 -0500 with value 'What does the fox say?'

TVar and atomically implement a software transactional memory. A TVar is a single
-item container that always contains exactly one value. The atomically method
-allows you to modify a set of TVar objects with the guarantee that all of the
-updates are collectively atomic - they either all happen or none of them do -
-consistent - a TVar will never enter an illegal state - and isolated - atomic
-blocks never interfere with each other when they are running. You may recognise
-these properties from database transactions.

-
-
There are some very important and unusual semantics that you must be aware of:

-
-
    
-
  • Most importantly, the block that you pass to atomically may be executed more
-than once. In most cases your code should be free of side-effects, except for
-via TVar.
    • 
-
  • If an exception escapes an atomically block it will abort the transaction.
    • 
-
  • It is undefined behaviour to use callcc or Fiber with atomically.
    • 
-
  • If you create a new thread within an atomically, it will not be part of
-the transaction. Creating a thread counts as a side-effect.
    • 
-

-
-
We implement nested transactions by flattening.

-
-
We only support strong isolation if you use the API correctly. In order words,
-we do not support strong isolation.

-
-
Our implementation uses a very simple two-phased locking with versioned locks algorithm, as per [1]. In the future we will look at more advanced algorithms, contention management and using existing Java implementations when in JRuby.

Motivation

-
-
Consider an application that transfers money between bank accounts. We want to
-transfer money from one account to another. It is very important that we don't
-lose any money! But it is also important that we can handle many account
-transfers at the same time, so we run them concurrently, and probably also in
-parallel.

-
-
This code shows us transferring ten pounds from one account to another.

-
-
a = BankAccount.new(100_000)
-b = BankAccount.new(100)
-
-a.value -= 10
-b.value += 10
-

-
-
Before we even start to talk about to talk about concurrency and parallelism, is
-this code safe? What happens if after removing money from account a, we get an
-exception? It's a slightly contrived example, but if the account totals were
-very large, adding to them could involve the stack allocation of a BigNum, and
-so could cause out of memory exceptions.  In that case the money would have
-disappeared from account a, but not appeared in account b. Disaster!

-
-
So what do we really need to do?

-
-
a = BankAccount.new(100_000)
-b = BankAccount.new(100)
-
-original_a = a.value
-a.value -= 10
-
-begin
-  b.value += 10
-rescue e =>
-  a.value = original_a
-  raise e
-end
-

-
-
This rescues any exceptions raised when setting b and will roll back the change
-we have already made to b. We'll keep this rescue code in mind, but we'll leave
-it out of future examples for simplicity.

-
-
That might have made the code work when it only runs sequentially. Lets start to
-consider some concurrency. It's obvious that we want to make the transfer of
-money mutually exclusive with any other transfers - in order words it is a
-critical section.

-
-
The usual solution to this would be to use a lock.

-
-
lock.synchronize do
-  a.value -= 10
-  b.value += 10
-end
-

-
-
That should work. Except we said we'd like these transfer to run concurrently,
-and in parallel. With a single lock like that we'll only let one transfer take
-place at a time. Perhaps we need more locks? We could have one per account:

-
-
a.lock.synchronize do
-  b.lock.synchronize do
-    a.value -= 10
-    b.value += 10
-  end
-end
-

-
-
However this is vulnerable to deadlock. If we tried to transfer from a to b, at
-the same time as from b to a, it's possible that the first transfer locks a, the
-second transfer locks b, and then they both sit there waiting forever to get the
-other lock. Perhaps we can solve that by applying a total ordering to the locks
-and always acquire them in the same order?

-
-
locks_needed = [a.lock, b.lock]
-locks_in_order = locks_needed.sort{ |x, y| x.number <=> y.number }
-
-locks_in_order[0].synchronize do
-  locks_in_order[1].synchronize do
-    a.value -= 10
-    b.value += 10
-  end
-end
-

-
-
That might work. But we need to know exactly what locks we're going to need
-before we start. If there were conditions in side the transfer this might be
-more complicated. We also need to remember the rescue code we had above to deal
-with exceptions. This is getting out of hand - and it's where TVar comes in.

-
-
We'll model the accounts as TVar - transactional variable, and instead of
-locks we'll use Concurrent::atomically.

-
-
a = TVar.new(100_000)
-b = TVar.new(100)
-
-Concurrent::atomically do
-  a.value -= 10
-  b.value += 10
-end
-

-
-
That short piece of code effectively solves all the concerns we identified
-above. How it does it is described in the reference above. You just need to be
-happy that any two atomically blocks (we call them transactions) that use an
-overlapping set of TVar objects will appear to have happened as if there was a
-big global lock on them, and that if any exception is raised in the block, it
-will be as if the block never happened. But also keep in mind the important
-points we detailed right at the start of the article about side effects and
-repeated execution.

-
-
Evaluation

-
-
We evaluated the performance of our TVar implementation using a bank account simulation with a range of synchronisation implementations. The simulation maintains a set of bank account totals, and runs transactions that either get a summary statement of multiple accounts (a read-only operation) or transfers a sum from one account to another (a read-write operation).

-
-
We implemented a bank that does not use any synchronisation (and so creates inconsistent totals in accounts), one that uses a single global (or 'coarse') lock (and so won't scale at all), one that uses one lock per account (and so has a complicated system for locking in the correct order) and one using our TVar and atomically.

-
-
We ran 1 million transactions divided equally between a varying number of threads on a system that has at least that many physical cores. The transactions are made up of a varying mixture of read-only and read-write transactions. We ran each set of transactions thirty times, discarding the first ten and then taking an algebraic mean. These graphs show only the simple mean. Our tvars-experiments branch includes the benchmark used, full details of the test system, and all the raw data.

-
-
Using JRuby using 75% read-write transactions, we can compare how the different implementations of bank accounts scales to more cores. That is, how much faster it runs if you use more cores.

-
-

-
-
We see that the coarse lock implementation does not scale at all, and in fact with more cores only wastes more time in contention for the single global lock. We see that the unsynchronised implementation doesn't seem to scale well - which is strange as there should be no overhead, but we'll explain that in a second. We see that the fine lock implementation seems to scale better, and that the TVar implementation scales the best.

-
-
So the TVar implementation scales very well, but how absolutely fast is it?

-
-

-
-
Well, that's the downside. The unsynchronised implementation doesn't scale well because it's so fast in the first place, and probably because we're bound on access to the memory - the threads don't have much work to do, so no matter how many threads we have the system is almost always reaching out to the L3 cache or main memory. However remember that the unsynchronised implementation isn't correct - the totals are wrong at the end. The coarse lock implementation has an overhead of locking and unlocking. The fine lock implementation has a greater overhead as as the locking scheme is complicated to avoid deadlock. It scales better, however, actually allowing transactions to be processed in parallel. The TVar implementation has a greater overhead still - and it's pretty huge. That overhead is the cost for the simple programming model of an atomic block.

-
-
So that's what TVar gives you at the moment - great scalability, but it has a high overhead. That's pretty much the state of software transactional memory in general. Perhaps hardware transactional memory will help us, or perhaps we're happy anyway with the simpler and safer programming model that the TVar gives us.

-
-
We can also use this experiment to compare different implementations of Ruby. We looked at just the TVar implementation and compared MRI 2.1.1, Rubinius 2.2.6, and JRuby 1.7.11, again at 75% write transactions.

-
-

-
-
We see that MRI provides no scalability, due to the global interpreter lock (GIL). JRuby seems to scale better than Rubinius for this workload (there are of course other workloads).

-
-
As before we should also look at the absolute performance, not just the scalability.

-
-

-
-
Again, JRuby seems to be faster than Rubinius for this experiment. Interestingly, Rubinius looks slower than MRI for 1 core, but we can get around that by using more cores.

-
-
We've used 75% read-write transactions throughout. We'll just take a quick look at how the scalability varies for different workloads, for scaling between 1 and 2 threads. We'll admit that we used 75% read-write just because it emphasised the differences.

-
-

-
-
Finally, we can also run on a larger machine. We repeated the experiment using a machine with 64 physical cores and JRuby.

-
-

-
-

-
-
Here you can see that TVar does become absolutely faster than using a global lock, at the slightly ridiculously thread-count of 50. It's probably not statistically significant anyway.

  • ImmutableStruct Immutable struct where values are set at construction and cannot be changed later.
    • 
-
  • MutableStruct Synchronized, mutable struct where values can be safely changed at any time.
    • 
-
  • SettableStruct Synchronized, write-once struct where values can be set at most once, either at construction or any time thereafter.

Thread-safe variables:

 
 
    
-
  • Agent: A way to manage shared, mutable, asynchronous, independent state. Based on Clojure's Agent.
    • 
-
  • Atom: A way to manage shared, mutable, synchronous, independent state. Based on Clojure's Atom.
    • 
-
  • AtomicBoolean A boolean value that can be updated atomically.
    • 
-
  • AtomicFixnum A numeric value that can be updated atomically.
    • 
-
  • AtomicReference An object reference that may be updated atomically.
    • 
-
  • Exchanger A synchronization point at which threads can pair and swap elements within pairs. Based on Java's Exchanger.
    • 
-
  • MVar A synchronized single element container. Based on Haskell's MVar and Scala's MVar.
    • 
-
  • ThreadLocalVar A variable where the value is different for each thread.
    • 
-
  • TVar A transactional variable implementing software transactional memory (STM). Based on Clojure's Ref.

Thread Synchronization Classes and Algorithms

 
 
    
-
  • CountDownLatch A synchronization object that allows one thread to wait on multiple other threads.
    • 
-
  • CyclicBarrier A synchronization aid that allows a set of threads to all wait for each other to reach a common barrier point.
    • 
-
  • Event Old school kernel-style event.
    • 
-
  • IVar Similar to a "future" but can be manually assigned once, after which it becomes immutable.
    • 
-
  • ReadWriteLock A lock that supports multiple readers but only one writer.
    • 
-
  • ReentrantReadWriteLock A read/write lock with reentrant and upgrade features.
    • 
-
  • Semaphore A counting-based locking mechanism that uses permits.

    Modern concurrency tools for Ruby. Inspired by
+Erlang,
+Clojure,
+Scala,
+Haskell,
+F#,
+C#,
+Java,
+and classic concurrency patterns.
    
+
+
    
+
+
    The design goals of this gem are:
    
+
+
      
+
    •   Be an 'unopinionated' toolbox that provides useful utilities without debating which is better 
+or why
      • 
+
    •   Remain free of external gem dependencies
      • 
+
    •   Stay true to the spirit of the languages providing inspiration
      • 
+
    •   But implement in a way that makes sense for Ruby
      • 
+
    •   Keep the semantics as idiomatic Ruby as possible
      • 
+
    •   Support features that make sense in Ruby
      • 
+
    •   Exclude features that don't make sense in Ruby
      • 
+
    •   Be small, lean, and loosely coupled
      • 
+
    •   Thread-safety
      • 
+
    •   Backward compatibility
      •

    Contributing
    
+
+
    This gem depends on 
+contributions and we 
+appreciate your help. Would you like to contribute? Great! Have a look at 
+issues with looking-for-contributor label. And if you pick something up let us know on the issue.
    
+
+
    Thread Safety
    
+
+
    Concurrent Ruby makes one of the strongest thread safety guarantees of any Ruby concurrency 
+library, providing consistent behavior and guarantees on all three of the main Ruby interpreters 
+(MRI/CRuby, JRuby, and Rubinius).
    
+
+
    Every abstraction in this library is thread safe. Specific thread safety guarantees are documented 
+with each abstraction.
    
+
+
    It is critical to remember, however, that Ruby is a language of mutable references. No
+concurrency library for Ruby can ever prevent the user from making thread safety mistakes (such as
+sharing a mutable object between threads and modifying it on both threads) or from creating
+deadlocks through incorrect use of locks. All the library can do is provide safe abstractions which
+encourage safe practices. Concurrent Ruby provides more safe concurrency abstractions than any
+other Ruby library, many of which support the mantra of 
+"Do not communicate by sharing memory; instead, share memory by communicating".
+Concurrent Ruby is also the only Ruby library which provides a full suite of thread safe and
+immutable variable types and data structures.
    
+
+
    We've also initiated discussion to document memory model of Ruby which 
+would provide consistent behaviour and guarantees on all three of the main Ruby interpreters 
+(MRI/CRuby, JRuby, Rubinius, TruffleRuby).
    
+
+
    Features & Documentation
    
+
+
    The primary site for documentation is the automatically generated 
+API documentation which is up to 
+date with latest release. This readme matches the master so may contain new stuff not yet 
+released.
    
+
+
    We also have a IRC (gitter).
    
+
+
    Versioning
    
+
+
      
+
    •   concurrent-ruby uses Semantic Versioning
      • 
+
    •   concurrent-ruby-ext has always same version as concurrent-ruby
      • 
+
    •   concurrent-ruby-edge will always be 0.y.z therefore following 
+point 4 applies "Major version zero 
+(0.y.z) is for initial development. Anything may change at any time. The 
+public API should not be considered stable." However we additionally use 
+following rules:
+
+
        
+
      •   Minor version increment means incompatible changes were made
        • 
+
      •   Patch version increment means only compatible changes were made
        • 
+
      • 
+
    
+
+
    General-purpose Concurrency Abstractions
    
+
+
      
+
    •   Async:
+A mixin module that provides simple asynchronous behavior to a class. Loosely based on Erlang's 
+gen_server.
      • 
+
    •   ScheduledTask:
+Like a Future scheduled for a specific future time.
      • 
+
    •   TimerTask:
+A Thread that periodically wakes up to perform work at regular intervals.
      • 
+
    •   Promises:
+Unified implementation of futures and promises which combines features of previous Future,
+Promise, IVar, Event, dataflow, Delay, and (partially) TimerTask into a single 
+framework. It extensively uses the new synchronization layer to make all the features 
+non-blocking and lock-free, with the exception of obviously blocking operations like 
+#wait, #value. It also offers better performance.
      • 
+
    
+
+
    Thread-safe Value Objects, Structures, and Collections
    
+
+
    Collection classes that were originally part of the (deprecated) thread_safe gem:
    
+
+
      
+
    •   Array A thread-safe
+subclass of Ruby's standard Array.
      • 
+
    •   Hash A thread-safe
+subclass of Ruby's standard Hash.
      • 
+
    •   Set A thread-safe
+subclass of Ruby's standard Set.
      • 
+
    •   Map A hash-like object
+that should have much better performance characteristics, especially under high concurrency, 
+than Concurrent::Hash.
      • 
+
    •   Tuple A fixed size
+array with volatile (synchronized, thread safe) getters/setters.
      • 
+
    
+
+
    Value objects inspired by other languages:
    
+
+
+
+
    Structure classes derived from Ruby's Struct:
    
+
+
      
+
    •   ImmutableStruct
+Immutable struct where values are set at construction and cannot be changed later.
      • 
+
    •   MutableStruct
+Synchronized, mutable struct where values can be safely changed at any time.
      • 
+
    •   SettableStruct
+Synchronized, write-once struct where values can be set at most once, either at construction 
+or any time thereafter.
      • 
+
    
+
+
    Thread-safe variables:
    
+
+
      
+
    •   Agent: A way to
+manage shared, mutable, asynchronous, independent state. Based on Clojure's 
+Agent.
      • 
+
    •   Atom: A way to manage
+shared, mutable, synchronous, independent state. Based on Clojure's 
+Atom.
      •

      • 
+
    •   AtomicFixnum
+A numeric value that can be updated atomically.
      • 
+
    •   AtomicReference
+An object reference that may be updated atomically.
      • 
+
    •   Exchanger
+A synchronization point at which threads can pair and swap elements within pairs. Based on 
+Java's Exchanger.
      • 
+
    •   MVar A synchronized
+single element container. Based on Haskell's 
+MVar and 
+Scala's MVar.
      • 
+
    •   ThreadLocalVar
+A variable where the value is different for each thread.
      • 
+
    •   TVar A transactional
+variable implementing software transactional memory (STM). Based on Clojure's 
+Ref.
      • 
+
    
+
+
    Java-inspired ThreadPools and Other Executors
    
+
+
      
+
    •   See the thread pool
+overview, which also contains a list of other Executors available.
      • 
+
    
+
+
    Thread Synchronization Classes and Algorithms
    
+
+
      
+
    •   CountDownLatch
+A synchronization object that allows one thread to wait on multiple other threads.
      • 
+
    •   CyclicBarrier
+A synchronization aid that allows a set of threads to all wait for each other to reach a common barrier point.
      • 
+
    •   Event Old school
+kernel-style event.
      • 
+
    •   ReadWriteLock

    •   Semaphore
+A counting-based locking mechanism that uses permits.
      • 
+
    •   AtomicMarkableReference
      • 
+
    
+
+
    Deprecated
    
+
+
    Deprecated features are still available and bugs are being fixed, but new features will not be added.
    
+
+
      
+
    •   Future:
+An asynchronous operation that produces a value. Replaced by 
+Promises.
+
+
        
+
      •   .dataflow:
+Built on Futures, Dataflow allows you to create a task that will be scheduled when all of 
+its data dependencies are available. Replaced by 
+Promises.
        • 
+
      • 
+
    •   Promise: Similar
+to Futures, with more features. Replaced by 
+Promises.
      • 
+
    •   Delay Lazy evaluation
+of a block yielding an immutable result. Based on Clojure's 
+delay. Replaced by 
+Promises.
      • 
+
    •   IVar Similar to a
+"future" but can be manually assigned once, after which it becomes immutable. Replaced by 
+Promises.
      • 
+
    
+
+
    Edge Features
    
+
+
    These are available in the concurrent-ruby-edge companion gem.
    
+
+
    These features are under active development and may change frequently. They are expected not to
+keep backward compatibility (there may also lack tests and documentation). Semantic versions will
+be obeyed though. Features developed in concurrent-ruby-edge are expected to move to
+concurrent-ruby when final.
    
+
+
      
+
    •   Actor: Implements
+the Actor Model, where concurrent actors exchange messages.
+Status: Partial documentation and tests; depends on new future/promise framework; stability is good.
      • 
+
    •   Channel:
+Communicating Sequential Processes (CSP).
+Functionally equivalent to Go channels with additional
+inspiration from Clojure core.async.
+Status: Partial documentation and tests.
      • 
+
    •   LazyRegister
      • 
+
    •   LockFreeLinkedSet
+Status: will be moved to core soon.
      • 
+
    •   LockFreeStack
+Status: missing documentation and tests.
      •

+
+
    Supported Ruby versions
    
+
+
    MRI 2.0 and above, JRuby 9000, TruffleRuby are supported. 
+This gem should be fully compatible with any interpreter that is compliant with Ruby 2.0 or newer.
+Java 8 is preferred for JRuby but every Java version on which JRuby 9000 runs is supported.
    
+
+
    The legacy support for Rubinius is kept but it is no longer maintained, if you would like to help 
+please respond to #739.
    
+
+
    Usage
    
+
+
    Everything within this gem can be loaded simply by requiring it:
    
+
+
    require 'concurrent'
+
    
+
+
    Requiring only specific abstractions from Concurrent Ruby is not yet supported.
    
+
+
    To use the tools in the Edge gem it must be required separately:
    
+
+
    require 'concurrent-edge'
+
    
+
+
    If the library does not behave as expected, Concurrent.use_stdlib_logger(Logger::DEBUG) could 
+help to reveal the problem.
    
+
+
    Installation
    
+
+
    gem install concurrent-ruby
+
    
+
+
    or add the following line to Gemfile:
    
+
+
    gem 'concurrent-ruby', require: 'concurrent'
+
    
+
+
    and run bundle install from your shell.
    
+
+
    Edge Gem Installation
    
+
+
    The Edge gem must be installed separately from the core gem:
    
+
+
    gem install concurrent-ruby-edge
+
    
+
+
    or add the following line to Gemfile:
    
+
+
    gem 'concurrent-ruby-edge', require: 'concurrent-edge'
+
    
+
+
    and run bundle install from your shell.
    
+
+
    C Extensions for MRI
    
+
+
    Potential performance improvements may be achieved under MRI by installing optional C extensions.
+To minimise installation errors the C extensions are available in the concurrent-ruby-ext
+extension gem. concurrent-ruby and concurrent-ruby-ext are always released together with same
+version. Simply install the extension gem too:
    
+
+
    gem install concurrent-ruby-ext
+
    
+
+
    or add the following line to Gemfile:
    
+
+
    gem 'concurrent-ruby-ext'
+
    
+
+
    and run bundle install from your shell.
    
+
+
    In code it is only necessary to
    
+
+
    require 'concurrent'
+
    
+
+
    The concurrent-ruby gem will automatically detect the presence of the concurrent-ruby-ext gem
+and load the appropriate C extensions.
    
+
+
    Note For gem developers
    
+
+
    No gems should depend on concurrent-ruby-ext. Doing so will force C extensions on your users. The
+best practice is to depend on concurrent-ruby and let users to decide if they want C extensions.

+
+  
+
+  
+
    
+  
    
+    
    Run a block that reads and writes TVars as a single atomic transaction.
+With respect to the value of TVar objects, the transaction is atomic, in
+that it either happens or it does not, consistent, in that the TVar
+objects involved will never enter an illegal state, and isolated, in that
+transactions never interfere with each other. You may recognise these
+properties from database transactions.
    
+
+
    There are some very important and unusual semantics that you must be aware of:
    
+
+
      
+
    • Most importantly, the block that you pass to atomically may be executed
+more than once. In most cases your code should be free of
+side-effects, except for via TVar.
      • 
+
    • If an exception escapes an atomically block it will abort the transaction.
      • 
+
    • It is undefined behaviour to use callcc or Fiber with atomically.
      • 
+
    • If you create a new thread within an atomically, it will not be part of
+the transaction. Creating a thread counts as a side-effect.
      • 
+
    
+
+
    Transactions within transactions are flattened to a single transaction.
    
+
+
+  
    
+
    
+
    
+  
+  
    
+    
    Examples:
    
+    
+      
+      
    a = new TVar(100_000)
+b = new TVar(100)
+
+Concurrent::atomically do
+  a.value -= 10
+  b.value += 10

    Dataflow allows you to create a task that will be scheduled when all of its data dependencies are available.
+Data dependencies are Future values. The dataflow task itself is also a Future value, so you can build up a graph of these tasks, each of which is run when all the data and other tasks it depends on are available or completed. 
    
+
+
    Our syntax is somewhat related to that of Akka's flow and Habanero Java's DataDrivenFuture. However unlike Akka we don't schedule a task at all until it is ready to run, and unlike Habanero Java we pass the data values into the task instead of dereferencing them again in the task. 
    
+
+
    The theory of dataflow goes back to the 70s. In the terminology of the literature, our implementation is coarse-grained, in that each task can be many instructions, and dynamic in that you can create more tasks within other tasks. 
    
+
+
    Example
    
+
+
    A dataflow task is created with the dataflow method, passing in a block.
    
+
+
    task = Concurrent::dataflow { 14 }
+
    
+
+
    This produces a simple Future value. The task will run immediately, as it has no dependencies. We can also specify Future values that must be available before a task will run. When we do this we get the value of those futures passed to our block. 
    
+
+
    a = Concurrent::dataflow { 1 }
+b = Concurrent::dataflow { 2 }
+c = Concurrent::dataflow(a, b) { |av, bv| av + bv }
+
    
+
+
    Using the dataflow method you can build up a directed acyclic graph (DAG) of tasks that depend on each other, and have the tasks run as soon as their dependencies are ready and there is CPU capacity to schedule them. This can help you create a program that uses more of the CPU resources available to you. 
    
+
+
    Derivation
    
+
+
    This section describes how we could derive dataflow from other primitives in this library.
    
+
+
    Consider a naive fibonacci calculator.
    
+
+
    def fib(n)
+  if n < 2
+    n
+  else
+    fib(n - 1) + fib(n - 2)
+  end
+end
+
+puts fib(14) #=> 377
+
    
+
+
    We could modify this to use futures.
    
+
+
    def fib(n)
+  if n < 2
+    Concurrent::Future.new { n }
+  else
+    n1 = fib(n - 1).execute
+    n2 = fib(n - 2).execute
+    Concurrent::Future.new { n1.value + n2.value }
+  end
+end
+
+f = fib(14) #=> #<Concurrent::Future:0x000001019ef5a0 ...
+f.execute   #=> #<Concurrent::Future:0x000001019ef5a0 ...
+
+sleep(0.5)
+
+puts f.value #=> 377
+
    
+
+
    One of the drawbacks of this approach is that all the futures start, and then most of them immediately block on their dependencies. We know that there's no point executing those futures until their dependencies are ready, so let's not execute each future until all their dependencies are ready. 
    
+
+
    To do this we'll create an object that counts the number of times it observes a future finishing before it does something - and for us that something will be to execute the next future. 
    
+
+
    class CountingObserver
+
+  def initialize(count, &block)
+    @count = count
+    @block = block
+  end
+
+  def update(time, value, reason)
+    @count -= 1
+
+    if @count <= 0
+      @block.call()
+    end
+  end
+
+end
+
+def fib(n)
+  if n < 2
+    Concurrent::Future.new { n }.execute
+  else
+    n1 = fib(n - 1)
+    n2 = fib(n - 2)
+
+    result = Concurrent::Future.new { n1.value + n2.value }
+
+    barrier = CountingObserver.new(2) { result.execute }
+    n1.add_observer barrier
+    n2.add_observer barrier
+
+    n1.execute
+    n2.execute
+
+    result
+  end
+end
+
    
+
+
    We can wrap this up in a dataflow utility.
    
+
+
    f = fib(14) #=> #<Concurrent::Future:0x00000101fca308 ...
+sleep(0.5)
+
+puts f.value #=> 377
+
+def dataflow(*inputs, &block)
+  result = Concurrent::Future.new(&block)
+
+  if inputs.empty?
+    result.execute
+  else
+    barrier = CountingObserver.new(inputs.size) { result.execute }
+
+    inputs.each do |input|
+      input.add_observer barrier
+    end
+  end
+
+  result
+end
+
+def fib(n)
+  if n < 2
+    dataflow { n }
+  else
+    n1 = fib(n - 1)
+    n2 = fib(n - 2)
+    dataflow(n1, n2) { n1.value + n2.value }
+  end
+end
+
+f = fib(14) #=> #<Concurrent::Future:0x00000101fca308 ...
+sleep(0.5)
+
+puts f.value #=> 377
+
    
+
+
    Since we know that the futures the dataflow computation depends on are already going to be available when the future is executed, we might as well pass the values into the block so we don't have to reference the futures inside the block. This allows us to write the dataflow block as straight non-concurrent code without reference to futures. 
    
+
+
    def dataflow(*inputs, &block)
+  result = Concurrent::Future.new do
+    values = inputs.map { |input| input.value }
+    block.call(*values)
+  end
+
+  if inputs.empty?
+    result.execute
+  else
+    barrier = CountingObserver.new(inputs.size) { result.execute }
+
+    inputs.each do |input|
+      input.add_observer barrier
+    end
+  end
+
+  result
+end
+
+def fib(n)
+  if n < 2
+    Concurrent::dataflow { n }
+  else
+    n1 = fib(n - 1)
+    n2 = fib(n - 2)
+    Concurrent::dataflow(n1, n2) { |v1, v2| v1 + v2 }
+  end

    this option should be needed only because of at_exit ordering
+issues which may arise when running some of the testing frameworks.
+E.g. Minitest's test-suite runs itself in at_exit callback which
+executes after the pools are already terminated. Then auto termination
+needs to be disabled and called manually after test-suite ends.
    
+
    
+  
    
+
+  
    
+    Note:
+    
    This method should never be called
+from within a gem. It should only be used from within the main
+application and even then it should be used only when necessary.
    
+
    
+  
    
+
+
    Disables AtExit handlers including pool auto-termination handlers.
+When disabled it will be the application programmer's responsibility
+to ensure that the handlers are shutdown properly prior to application
+exit by calling AtExitImplementation.new.install.run method.

    Time calculations on all platforms and languages are sensitive to
+changes to the system clock. To alleviate the potential problems
+associated with changing the system clock while an application is running,
+most modern operating systems provide a monotonic clock that operates
+independently of the system clock. A monotonic clock cannot be used to
+determine human-friendly clock times. A monotonic clock is used exclusively
+for calculating time intervals. Not all Ruby platforms provide access to an
+operating system monotonic clock. On these platforms a pure-Ruby monotonic
+clock will be used as a fallback. An operating system monotonic clock is both
+faster and more reliable than the pure-Ruby implementation. The pure-Ruby
+implementation should be fast and reliable enough for most non-realtime
+operations. At this time the common Ruby platforms that provide access to an
+operating system monotonic clock are MRI 2.1 and above and JRuby (all versions).

    Actor model
    
+
+
      
+
    •  Light-weighted running on thread-pool.
      • 
+
    •  Inspired by Akka and Erlang.
      • 
+
    •  Modular.

    This Actor model implementation makes actors very cheap to create and discard.
+Thousands of actors can be created, allowing you to break the program into smaller 
+maintainable pieces, without violating the single responsibility principle.
    
+
+
    What is an actor model?
    
+
+
    Actor-based concurrency is all the rage in some circles. Originally described in 1973, the actor model is a paradigm 
+for creating asynchronous, concurrent objects  that is becoming increasingly popular. Much has changed since actors 
+were first  written about four decades ago, which has led to a serious fragmentation within  the actor community. 
+There is no universally accepted, strict definition of "actor" and actor implementations differ widely between 
+languages and libraries.  
    
+
+
    Wiki definition is pretty good:
+The actor model in computer science is a mathematical model of concurrent computation
+that treats actors as the universal primitives of concurrent digital computation:
+in response to a message that it receives, an actor can make local decisions,
+create more actors, send more messages, and determine how to respond to the next
+message received.
    
+
+
    Why?
    
+
+
    Concurrency is hard to get right, actors are one of many ways how to simplify the problem.
    
+
+
    Quick example
    
+
+
    An example:
    
+
+
    class Counter < Concurrent::Actor::Context
+  # Include context of an actor which gives this class access to reference
+  # and other information about the actor
+
+  # use initialize as you wish
+  def initialize(initial_value)
+    @count = initial_value
+  end
+
+  # override on_message to define actor's behaviour
+  def on_message(message)
+    if Integer === message
+      @count += message
+    end
+  end
+end #
+
+# Create new actor naming the instance 'first'.
+# Return value is a reference to the actor, the actual actor is never returned.
+counter = Counter.spawn(:first, 5)
+
+# Tell a message and forget returning self.
+counter.tell(1)
+counter << 1
+# (First counter now contains 7.)
+
+# Send a messages asking for a result.
+counter.ask(0).class
+counter.ask(0).value
+
    
+
+
    class Adder < Concurrent::Actor::RestartingContext
+  def initialize(init)
+    @count = init
+  end
+
+  def on_message(message)
+    case message
+    when :add
+      @count += 1
+    else
+      # pass to ErrorsOnUnknownMessage behaviour, which will just fail
+      pass
+    end
+  end
+end 
+
+# `link: true` makes the actor linked to root actor and supervised
+# which is default behavior
+adder = Adder.spawn(name: :adder, link: true, args: [1])
+    # => #<Concurrent::Actor::Reference:0x7fbedd8e3d40 /adder (Adder)>
+adder.parent
+    # => #<Concurrent::Actor::Reference:0x7fbedbaa1e90 / (Concurrent::Actor::Root)>
+
+# tell and forget
+adder.tell(:add).tell(:add)
+    # => #<Concurrent::Actor::Reference:0x7fbedd8e3d40 /adder (Adder)>
+# ask to get result
+adder.ask!(:add)                                   # => 4
+# fail the actor
+adder.ask!(:bad) rescue $!
+    # => #<Concurrent::Actor::UnknownMessage: :bad from #<Thread:0x007fbedb8809b8>>
+# actor is restarted with initial values
+adder.ask!(:add)                                   # => 2
+adder.ask!(:terminate!)                            # => true
    
+
+
    Spawning actors
    
+
+
+
+
    Sending messages
    
+
+
      
+
    •   Reference#tell 
+Sends the message asynchronously to the actor and immediately returns
+self (the reference) allowing to chain message telling.
      • 
+
    •   Reference#ask
+testing and when it returns very shortly. It can lead to deadlock if all threads in
+global_io_executor will block on while asking. It's fine to use it form outside of actors and
+global_io_executor.
      • 
+
    •   Reference#ask!
+Sends the message synchronously and blocks until the message
+is processed. Raises on error.
      • 
+
    
+
+
    Messages are processed in same order as they are sent by a sender. It may interleaved with
+messages from other senders though.
    
+
+
    Immutability
    
+
+
    Messages sent between actors should be immutable. Gems like
    
+
+
      
+
    • Algebrick - Typed struct on steroids based on
+algebraic types and pattern matching
      • 
+
    • Hamster - Efficient, Immutable, Thread-Safe
+Collection classes for Ruby
      • 
+
    
+
+
    are very helpful.
    
+
+
    require 'algebrick'                                # => true
+
+# Actor message protocol definition with Algebrick
+Protocol = Algebrick.type do
+  variants Add      = type { fields! a: Numeric, b: Numeric },
+           Subtract = type { fields! a: Numeric, b: Numeric }
+end                                                # => Protocol(Add | Subtract)
+
+class Calculator < Concurrent::Actor::RestartingContext
+  include Algebrick::Matching
+
+  def on_message(message)
+    # pattern matching on the message with deconstruction
+    # ~ marks values which are passed to the block
+    match message,
+          (on Add.(~any, ~any) do |a, b|
+            a + b
+          end),
+          # or using multi-assignment
+          (on ~Subtract do |(a, b)|
+            a - b
+          end)
+  end
+end 
+
+calculator = Calculator.spawn('calculator')
+    # => #<Concurrent::Actor::Reference:0x7fbedba52d90 /calculator (Calculator)>
+addition = calculator.ask Add[1, 2]
+    # => <#Concurrent::Promises::Future:0x7fbedc05f7b0 pending>
+subtraction = calculator.ask Subtract[1, 0.5]
+    # => <#Concurrent::Promises::Future:0x7fbedd891388 pending>
+results = (addition & subtraction)
+    # => <#Concurrent::Promises::Future:0x7fbedc04eeb0 pending>
+results.value!                                     # => [3, 0.5]
+
+calculator.ask! :terminate!                        # => true
    
+
+
    Actor definition
    
+
+
    New actor is defined by subclassing RestartingContext, Context and defining its abstract methods.
+AbstractContext can be subclassed directly to implement more specific behaviour see Root implementation.
    
+
+
+
+
    Example of ac actor definition:
    
+
+
    Message = Struct.new :action, :value 
+
+class AnActor < Concurrent::Actor::RestartingContext
+  def initialize(init)
+    @counter = init
+  end
+
+  # override #on_message to define actor's behaviour on message received
+  def on_message(message)
+    case message.action
+    when :add
+      @counter = @counter + message.value
+    when :subtract
+      @counter = @counter - message.value
+    when :value
+      @counter
+    else
+      pass
+    end
+  end
+
+  # set counter to zero when there is an error
+  def on_event(event)
+    if event == :reset
+      @counter = 0 # ignore initial value
+    end
+  end
+end 
+
+an_actor = AnActor.spawn name: 'an_actor', args: 10 
+an_actor << Message.new(:add, 1) << Message.new(:subtract, 2) 
+an_actor.ask!(Message.new(:value, nil))            # => 9
+an_actor << :boo << Message.new(:add, 1) 
+an_actor.ask!(Message.new(:value, nil))            # => 1
+an_actor << :terminate!
+    # => #<Concurrent::Actor::Reference:0x7fbedc137688 /an_actor (AnActor)>
    
+
+
    See methods of AbstractContext what else can be tweaked, e.g AbstractContext#default_reference_class
    
+
+
    Reference
    
+
+
    Reference is public interface of Actor instances. It is used for sending messages and can
+be freely passed around the application. It also provides some basic information about the actor,
+see PublicDelegations.
    
+
+
    AdHoc.spawn('printer') { -> message { puts message } }
+# => #<Concurrent::Actor::Reference:0x7fd0d2883218 /printer (Concurrent::Actor::Utils::AdHoc)>
+#                                   ^object_id     ^path     ^context class
+
    
+
    
+
+
    Garbage collection
    
+
+
    Spawned actor cannot be garbage-collected until it's terminated. There is a reference held in the parent actor.
    
+
+
    Parent-child relationship, name, and path
    
+
+
      
+
    •   Core#name 
+The name of actor instance, it should be uniq (not enforced). Allows easier orientation
+between actor instances.
      • 
+
    •   Core#path
+Path of this actor. It is used for easier orientation and logging.
+Path is constructed recursively with: parent.path + self.name up to a Actor.root,
+e.g. /an_actor/its_child.
      • 
+
    •   Core#parent
+A parent Actor. When actor is spawned the Actor.current becomes its parent.
+When actor is spawned from a thread outside of an actor (Actor.current is nil) Actor.root is assigned. 
      • 
+
    
+
+
    Behaviour
    
+
+
    Actors have modular architecture, which is achieved by combining a light core with chain of
+behaviours. Each message or internal event propagates through the chain allowing the
+behaviours react based on their responsibility.
    
+
+
      
+
    • Behaviour::Linking:
      
+
+
      
+
      Links the actor to other actors and sends actor's events to them,
+like: :terminated, :paused, :resumed, errors, etc.
+Linked actor needs to handle those messages.
      
+
+
      listener = AdHoc.spawn name: :listener do
+  lambda do |message|
+    case message
+    when Reference
+      if message.ask!(:linked?)
+        message << :unlink
+      else
+        message << :link
+      end
+    else
+      puts "got event #{message.inspect} from #{envelope.sender}"
+    end
+  end
+end
+
+an_actor = AdHoc.spawn name: :an_actor, supervise: true, behaviour_definition: Behaviour.restarting_behaviour_definition do
+  lambda { |message| raise 'failed'}
+end
+
+# link the actor
+listener.ask(an_actor).wait
+an_actor.ask(:fail).wait
+# unlink the actor
+listener.ask(an_actor).wait
+an_actor.ask(:fail).wait
+an_actor << :terminate!
+
      
+
+
      produces only two events, other events happened after unlinking
      
+
+
      got event #<RuntimeError: failed> from #<Concurrent::Actor::Reference /an_actor (Concurrent::Actor::Utils::AdHoc)>
+got event :reset from #<Concurrent::Actor::Reference /an_actor (Concurrent::Actor::Utils::AdHoc)>
+
      
+
      
+
      • 
+
    • Behaviour::Awaits:
      
+
+
      
+
      Accepts :await messages. Which allows to wait on Actor to process all previously send
+messages.
      
+
+
      actor << :a << :b
+actor.ask(:await).wait # blocks until :a and :b are processed
+
      
+
      
+
      • 
+
    • Behaviour::Pausing:
      
+
+
      
+
      Allows to pause actors on errors.
+When paused all arriving messages are collected and processed after the actor
+is resumed or reset. Resume will simply continue with next message.
+Reset also reinitialized context.
      
+
      • 
+
    • Behaviour::Supervising:
      
+
+
      
+
      Handles supervised actors. Handle configures what to do with failed child: :terminate!, :resume!, :reset!,
+or :restart!. Strategy sets :one_for_one (restarts just failed actor) or :one_for_all (restarts all child actors).
      
+
      • 
+
    • Behaviour::Supervising:
      
+
+
      
+
      Handles supervised actors. Handle configures what to do with failed child: :terminate!, :resume!, :reset!,
+or :restart!. Strategy sets :one_for_one (restarts just failed actor) or :one_for_all (restarts all child actors).
      
+
      • 
+
    • Behaviour::ExecutesContext:
      
+
+
      
+
      Delegates messages and events to AbstractContext instance.
      
+
      • 
+
    • Behaviour::ErrorsOnUnknownMessage:
      
+
+
      
+
      Simply fails when message arrives here. It's usually the last behaviour.
      
+
      • 
+
    • Behaviour::Termination:
      
+
+
      
+
      Handles actor termination. Waits until all its children are terminated,
+can be configured on behaviour initialization.
      
+
      • 
+
    • Behaviour::RemovesChild:
      
+
+
      
+
      Removes terminated children.
      
+
      • 
+
    
+
+
    If needed new behaviours can be added, or old one removed to get required behaviour.
    
+
+
+
    
+
+
    IO cooperation
    
+
+
    Actors are running on shared thread poll which allows user to create many actors cheaply.
+Downside is that these actors cannot be directly used to do IO or other blocking operations.
+Blocking operations could starve the default_task_pool. However there are two options:
    
+
+
      
+
    • Create an regular actor which will schedule blocking operations in global_operation_pool
+(which is intended for blocking operations) sending results back to self in messages.
      • 
+
    • Create an actor using global_operation_pool instead of global_task_pool, e.g.
+AnIOActor.spawn name: :blocking, executor: Concurrent.configuration.global_operation_pool.
      • 
+
    
+
+
    Example
    
+
+
    require 'concurrent'                               # => false
+
+# logger = Logger.new(STDOUT)
+# Concurrent.configuration.logger = logger.method(:add)
+
+# First option is to use operation pool
+
+class ActorDoingIO < Concurrent::Actor::RestartingContext
+  def on_message(message)
+    # do IO operation
+  end
+
+  def default_executor
+    Concurrent.global_io_executor
+  end
+end 
+
+actor_doing_io = ActorDoingIO.spawn :actor_doing_io
+    # => #<Concurrent::Actor::Reference:0x7fbedc146e80 /actor_doing_io (ActorDoingIO)>
+actor_doing_io.executor == Concurrent.global_io_executor
+    # => true
+
+# It can be also built into a pool so there is not too many IO operations
+
+class IOWorker < Concurrent::Actor::Context
+  def on_message(io_job)
+    # do IO work
+    sleep 0.1
+    puts "#{path} second:#{(Time.now.to_f*100).floor} message:#{io_job}"
+  end
+
+  def default_executor
+    Concurrent.global_io_executor
+  end
+end 
+
+pool = Concurrent::Actor::Utils::Pool.spawn('pool', 2) do |index|
+  IOWorker.spawn(name: "worker-#{index}")
+end
+    # => #<Concurrent::Actor::Reference:0x7fbedba83378 /pool (Concurrent::Actor::Utils::Pool)>
+
+pool << 1 << 2 << 3 << 4 << 5 << 6
+    # => #<Concurrent::Actor::Reference:0x7fbedba83378 /pool (Concurrent::Actor::Utils::Pool)>
+
+# prints two lines each second
+# /pool/worker-0 second:1414677666 message:1

    Dead letter routing
    
+
+
    see AbstractContext#dead_letter_routing description:
    
+
+
    
+
    Defines an actor responsible for dead letters. Any rejected message send
+with Reference#tell is sent there, a message with future is considered
+already monitored for failures. Default behaviour is to use
+AbstractContext#dead_letter_routing of the parent, so if no
+AbstractContext#dead_letter_routing method is overridden in
+parent-chain the message ends up in Actor.root.dead_letter_routing
+agent which will log warning.

    Alleged supervisor will receive errors from its supervised actors. They'll have to be handled manually.
    
+
+
    How to change supervision strategy?
    
+
+
    Use option behaviour_definition: Behaviour.restarting_behaviour_definition(:resume!) or 
+behaviour_definition: Behaviour.restarting_behaviour_definition(:reset!, :one_for_all)
    
+
+
    How to change behaviors?
    
+
+
    Any existing behavior can be subclassed 
    
+
+
    How to implement custom restarting?
    
+
+
    By subclassing Behaviour::Pausing and overriding Behaviour::Pausing#restart!. Implementing 
+AbstractContext#on_event could be also considered.
    
+
+
    We'll be happy to answer any other questions, 
+just open an Issue or find us on

    Simple benchmark Actor vs Celluloid, the numbers are looking good
+but you know how it is with benchmarks. Source code is in
+examples/actor/celluloid_benchmark.rb. It sends numbers between x actors
+and adding 1 until certain limit is reached.
    
+
+
    Benchmark legend:
    
+
+
      
+
    • mes.  - number of messages send between the actors
      • 
+
    • act.  - number of actors exchanging the messages
      • 
+
    • impl. - which gem is used
      •

    Overview
    
+  
    
+    
    
+  This class is abstract.
+  
    implement #on_message and #behaviour_definition
    
+
    
+
    
+
    New actor is defined by subclassing RestartingContext, Context and defining its abstract methods.
+AbstractContext can be subclassed directly to implement more specific behaviour see Root implementation.
    
+
+
+
+
    Example of ac actor definition:
    
+
+
    Message = Struct.new :action, :value 
+
+class AnActor < Concurrent::Actor::RestartingContext
+  def initialize(init)
+    @counter = init
+  end
+
+  # override #on_message to define actor's behaviour on message received
+  def on_message(message)
+    case message.action
+    when :add
+      @counter = @counter + message.value
+    when :subtract
+      @counter = @counter - message.value
+    when :value
+      @counter
+    else
+      pass
+    end
+  end
+
+  # set counter to zero when there is an error
+  def on_event(event)
+    if event == :reset
+      @counter = 0 # ignore initial value
+    end
+  end
+end 
+
+an_actor = AnActor.spawn name: 'an_actor', args: 10 
+an_actor << Message.new(:add, 1) << Message.new(:subtract, 2) 
+an_actor.ask!(Message.new(:value, nil))            # => 9
+an_actor << :boo << Message.new(:add, 1) 
+an_actor.ask!(Message.new(:value, nil))            # => 1
+an_actor << :terminate!
+    # => #<Concurrent::Actor::Reference:0x7fbedc137688 /an_actor (AnActor)>
    
+

    Defines an actor responsible for dead letters. Any rejected message send

+#dead_letter_routing method is overridden in
+parent-chain the message ends up in Actor.root.dead_letter_routing
+agent which will log warning.

Overview

+  

+    
Actors have modular architecture, which is achieved by combining a light core with chain of
+behaviours. Each message or internal event propagates through the chain allowing the
+behaviours react based on their responsibility.

+
+
    
+
  • Linking:
    
+
+
    
+
    Links the actor to other actors and sends actor's events to them,
+like: :terminated, :paused, :resumed, errors, etc.
+Linked actor needs to handle those messages.
    
+
+
    listener = AdHoc.spawn name: :listener do
+  lambda do |message|
+    case message
+    when Reference
+      if message.ask!(:linked?)
+        message << :unlink
+      else
+        message << :link
+      end
+    else
+      puts "got event #{message.inspect} from #{envelope.sender}"
+    end
+  end
+end
+
+an_actor = AdHoc.spawn name: :an_actor, supervise: true, behaviour_definition: Behaviour.restarting_behaviour_definition do
+  lambda { |message| raise 'failed'}
+end
+
+# link the actor
+listener.ask(an_actor).wait
+an_actor.ask(:fail).wait
+# unlink the actor
+listener.ask(an_actor).wait
+an_actor.ask(:fail).wait
+an_actor << :terminate!
+
    
+
+
    produces only two events, other events happened after unlinking
    
+
+
    got event #<RuntimeError: failed> from #<Concurrent::Actor::Reference /an_actor (Concurrent::Actor::Utils::AdHoc)>
+got event :reset from #<Concurrent::Actor::Reference /an_actor (Concurrent::Actor::Utils::AdHoc)>
+
    
+
    
+
    • 
+
  • Awaits:
    
+
+
    
+
    Accepts :await messages. Which allows to wait on Actor to process all previously send
+messages.
    
+
+
    actor << :a << :b
+actor.ask(:await).wait # blocks until :a and :b are processed
+
    
+
    
+
    • 
+
  • Pausing:
    
+
+
    
+
    Allows to pause actors on errors.
+When paused all arriving messages are collected and processed after the actor
+is resumed or reset. Resume will simply continue with next message.
+Reset also reinitialized context.
    
+
    • 
+
  • Supervising:
    
+
+
    
+
    Handles supervised actors. Handle configures what to do with failed child: :terminate!, :resume!, :reset!,
+or :restart!. Strategy sets :one_for_one (restarts just failed actor) or :one_for_all (restarts all child actors).

+or :restart!. Strategy sets :one_for_one (restarts just failed actor) or :one_for_all (restarts all child actors).
    
+
    • 
+
  • ExecutesContext:
    
+
+
    
+
    Delegates messages and events to AbstractContext instance.
    
+
    • 
+
  • ErrorsOnUnknownMessage:
    
+
+
    
+
    Simply fails when message arrives here. It's usually the last behaviour.
    
+
    • 
+
  • Termination:
    
+
+
    
+
    Handles actor termination. Waits until all its children are terminated,
+can be configured on behaviour initialization.
    
+
    • 
+
  • RemovesChild:
    
+
+
    
+
    Removes terminated children.
    
+
    • 
+

+
+
If needed new behaviours can be added, or old one removed to get required behaviour.

Overview

+  

+    
Any message reaching this behaviour is buffered. Only one message is is
+scheduled at any given time. Others are kept in buffer until another one
+can be scheduled. This effectively means that messages handled by
+behaviours before buffer have higher priority and they can be processed
+before messages arriving into buffer. This allows for the processing of
+internal actor messages like (:link, :supervise) first.

Overview

+  

+    
Links the actor to other actors and sends actor's events to them,
+like: :terminated, :paused, :resumed, errors, etc.
+Linked actor needs to handle those messages.

+
+
listener = AdHoc.spawn name: :listener do
+  lambda do |message|
+    case message
+    when Reference
+      if message.ask!(:linked?)
+        message << :unlink
+      else
+        message << :link
+      end
+    else
+      puts "got event #{message.inspect} from #{envelope.sender}"
+    end
+  end
+end
+
+an_actor = AdHoc.spawn name: :an_actor, supervise: true, behaviour_definition: Behaviour.restarting_behaviour_definition do
+  lambda { |message| raise 'failed'}
+end
+
+# link the actor
+listener.ask(an_actor).wait
+an_actor.ask(:fail).wait
+# unlink the actor
+listener.ask(an_actor).wait
+an_actor.ask(:fail).wait
+an_actor << :terminate!
+

+
+
produces only two events, other events happened after unlinking

+
+
got event #<RuntimeError: failed> from #<Concurrent::Actor::Reference /an_actor (Concurrent::Actor::Utils::AdHoc)>
+got event :reset from #<Concurrent::Actor::Reference /an_actor (Concurrent::Actor::Utils::AdHoc)>

TODO missing example

+

+  

+
+
Allows to pause actors on errors.
+When paused all arriving messages are collected and processed after the actor
+is resumed or reset. Resume will simply continue with next message.
+Reset also reinitialized context.

Overview

+  

+    
+  

+    Note:
+    
Whole class should be considered private. An user should use Contexts and References only.

+

+  

+
+  

+    Note:
+    
devel: core should not block on anything, e.g. it cannot wait on children to terminate
+that would eat up all threads in task pool and deadlock

+

+  

+
+
Core of the actor.
