Erlang OTP. Create scalable applications for e-commerce, telecommunication, and instant messaging with the help of this flexible programming language. What’s new in Erlang OTP Load comments. Erlang OTP All rights reserved. The anonymous function is named Smaller in the parameter list of the second definition of qsort so that it can be referenced by that name within that function.

It is not named in the first definition of qsort , which deals with the base case of an empty list and thus has no need of this function, let alone a name for it. Two forms of syntactic sugar are provided:. Erlang has no method to define classes, although there are external libraries available. Erlang is designed with a mechanism that makes it easy for external processes to monitor for crashes or hardware failures , rather than an in-process mechanism like exception handling used in many other programming languages.

Crashes are reported like other messages, which is the only way processes can communicate with each other, [26] and subprocesses can be spawned cheaply. A typical Erlang application is written in the form of a supervisor tree. This architecture is based on a hierarchy of processes in which the top level process is known as a “supervisor”.

The supervisor then spawns multiple child processes that act either as workers or more, lower level supervisors. Such hierarchies can exist to arbitrary depths and have proven to provide a highly scalable and fault-tolerant environment within which application functionality can be implemented. Within a supervisor tree, all supervisor processes are responsible for managing the lifecycle of their child processes, and this includes handling situations in which those child processes crash.

If the monitored process then crashes, the supervisor will receive a message containing a tuple whose first member is the atom ‘DOWN’. The supervisor is responsible firstly for listening for such messages and secondly, for taking the appropriate action to correct the error condition. Erlang’s main strength is support for concurrency. It has a small but powerful set of primitives to create processes and communicate among them. Erlang is conceptually similar to the language occam , though it recasts the ideas of communicating sequential processes CSP in a functional framework and uses asynchronous message passing.

They are neither operating system processes nor threads , but lightweight processes that are scheduled by BEAM. Like operating system processes but unlike operating system threads , they share no state with each other.

The estimated minimal overhead for each is words. While threads need external library support in most languages, Erlang provides language-level features to create and manage processes with the goal of simplifying concurrent programming.

Though all concurrency is explicit in Erlang, processes communicate using message passing instead of shared variables, which removes the need for explicit locks a locking scheme is still used internally by the VM. Inter-process communication works via a shared-nothing asynchronous message passing system: every process has a “mailbox”, a queue of messages that have been sent by other processes and not yet consumed.

A process uses the receive primitive to retrieve messages that match desired patterns. A message-handling routine tests messages in turn against each pattern, until one of them matches. When the message is consumed and removed from the mailbox the process resumes execution.

A message may comprise any Erlang structure, including primitives integers, floats, characters, atoms , tuples, lists, and functions. As the example shows, processes may be created on remote nodes, and communication with them is transparent in the sense that communication with remote processes works exactly as communication with local processes. Concurrency supports the primary method of error-handling in Erlang. When a process crashes, it neatly exits and sends a message to the controlling process which can then take action, such as starting a new process that takes over the old process’s task.

BEAM executes bytecode which is converted to threaded code at load time. Erlang supports language-level Dynamic Software Updating. To implement this, code is loaded and managed as “module” units; the module is a compilation unit. The system can keep two versions of a module in memory at the same time, and processes can concurrently run code from each.

The versions are referred to as the “new” and the “old” version. A process will not move into the new version until it makes an external call to its module. The practice of having a specific entry-point into a new version allows the programmer to transform state to what is needed in the newer version. In the example, the state is kept as an integer. In practice, systems are built up using design principles from the Open Telecom Platform, which leads to more code upgradable designs. Successful hot code loading is exacting.

Code must be written with care to make use of Erlang’s facilities. In , Ericsson released Erlang as free and open-source software to ensure its independence from a single vendor and to increase awareness of the language. Erlang, together with libraries and the real-time distributed database Mnesia , forms the OTP collection of libraries. Ericsson and a few other companies support Erlang commercially. Since the open source release, Erlang has been used by several firms worldwide, including Nortel and T-Mobile.
