 "A process is basically a thread with a message queue. Other processes can place items on this queue by sending the process a message. A process can check its queue for messages, blocking if none are pending, and process them as they are queued.\n\nFactor processes are very lightweight. Each process can take as little as 900 bytes of memory. This library has been tested running hundreds of thousands of simple processes.\n\nThe messages that are sent from process to process are any Factor value. Factor tuples are ideal for this sort of thing as you can send a tuple to a process and the predicate dispatch mechanism can be used to perform actions depending on what the type of the tuple is.\n\nProcesses are usually created using " { $link spawn } ". This word takes a quotation on the stack and starts a process that will execute that quotation asynchronously. When the quotation completes the process will die. 'spawn'  leaves on the stack the process object that was started. This object can be used to send messages to the process using " { $link send }  ".\n\n'send' will return immediately after placing the message in the target processes message queue.\n\nA process can get a message from its queue using " { $link receive } ". This will get the most recent message and leave it on the stack. If there are no messages in the queue the process will 'block' until a message is available. When a process is blocked it takes no CPU time at all."

 "A process can get access to its own process object using " { $link self } " so it can pass it to other processes. This allows the other processes to send messages back.

-ARTICLE: { "concurrency" "servers" } "Servers"
-"A common idiom is to create 'server' processes that act on messages that are sent to it. These follow a basic pattern of blocking until a message is received, processing that message then looping back to blocking for a message.\n\nThe following example shows a very simple server that expects an array as its message. The first item of the array should be the senders process object. If the second item is 'ping' then the server sends 'pong' back to the caller. If the second item is anything else then the server exits:"

-"Handling the deconstructing of messages and dispatching based on the message can be a bit of a chore. Especially in servers that take a number of different messages.

-{ $link send } " sends a message asynchronously, and the sending process continues immediately. The 'pong server' example shown previously all sent messages to the server and waited for a reply back from the server. This pattern of synchronous sending is made easier with " { $link send-synchronous } ".\n\nThis word will send a message to the given process and immediately block until a reply is received for this particular message send. It leaves the reply on the stack. Note that it doesn't wait for just any reply, it waits for a reply specifically to this send.\n\nTo do this it wraps the requested message inside a tagged message format using " { $link tag-message } ":"

The 'pong server' example shown previously all sent messages to the server and waited for a reply back from the server. This pattern of synchronous sending is made easier with " { $link send-synchronous } ".\n\nThis word will send a message to the given process and immediately block until a reply is received for this particular message send. It leaves the reply on the stack. Note that it doesn't wait for just any reply, it waits for a reply specifically to this send.\n\nTo do this it wraps the requested message inside a tagged message format using " { $link <synchronous> } ":"
+{ $code "\"My Message\" <synchronous> .\n => T{ synchronous f \"My Message\" ...from... ...tag... }" }
 "The message is wrapped in array where the first item is the sending process object, the second is a unique tag, and the third is the original message. Server processes can use the 'from' to reply to the process that originally sent the message. The tag is used in the receiving server to include the value in the reply. After the send-synchronous call the current process will block waiting for a reply that has the exact same tag. In this way you can be sure that the reply you got was for the specific message sent. Here is the pong-server recoded to use 'send-synchronous':"

 "Notice that the code to send the reply back to the original caller wraps the reply in an array where the first item is the tag originally sent. 'send-synchronous' only returns if it receives a reply containing that specific tag." ;

 "The concurrency library is based upon the style of concurrency used in systems like Erlang and Termite. It is built on top of the standard Factor lightweight thread system.\nA concurrency oriented program is one in which multiple processes run simultaneously in a single Factor image or across multiple running Factor instances. The processes can communicate with each other by asynchronous message sends. Although processes can share data via Factor's mutable data structures it is not recommended as the use of shared state concurrency is often a cause of problems."
