OTP 19.2

Wed, 14 Dec 2016 00:00:00 GMT

Some highlights for 19.2

STDLIB: The new behaviour gen_statem has been improved with 3 new features: the possibility to use old style non-proxy timeouts for gen_statem:call/2,3, state entry code, and state timeouts. These are backwards compatible. Minor code and documentation improvements has been performed including a borderline semantics correction of timeout zero handling.
SSL: Experimental version of DTLS. It is runnable but not complete and cannot be considered reliable for production usage. To use DTLS add the option {protocol, dtls} to ssl:connect and ssl:listen.
SSH: Extended the option silently_accept_hosts for ssh:connect to make it possible for the client to check the SSH host key fingerprint string. Se the reference manual for SSH.

Fifteenth ACM SIGPLAN Erlang Workshop

Sun, 18 Sep 2016 00:00:00 GMT

img src=http://www.erlang.org/upload/news/

Workshop Objectives

The Erlang Workshop aims to bring together the open source, academic, and industrial communities of Erlang, to discuss technologies and languages related to Erlang. The Erlang model of concurrent programming has been widely emulated, for example by Akka in Scala, and even new programming languages were designed atop of the Erlang VM, such as Elixir. Therefore we would like to broaden the scope of the workshop to include systems like those mentioned above.

The workshop will enable participants to familiarize themselves with recent developments on new techniques and tools, novel applications, draw lessons from users' experiences and identify research problems and common areas relevant to the practice of Erlang, Erlang-like languages, functional programming, distribution, concurrency etc.

We invite three types of submissions.

1. Technical papers describing interesting contributions either in theoretical work or real world applications. Submission related to Erlang, Elixir, Akka, CloudHaskell, Occam, and functional programming are welcome and encouraged. Topics of interest include (but are not limited to):

virtual machine extensions and compilation techniques
implementations and interfaces of Erlang in/with other languages
new tools (profilers, tracers, debuggers, testing frameworks etc.)
language extensions
formal semantics, correctness and verification
testing Erlang programs
program analysis and transformation
Erlang-like languages and technologies
functional languages and multi-processing
concurrency in functional languages
functional languages and distributed computing
parallel programming
pattern based programming
Erlang in education

The maximum length for technical papers is restricted to 12 pages.

2. Experience reports describing uses of Erlang in the "real-world", Erlang libraries for specific tasks, experiences from using Erlang in specific application domains, reusable programming idioms and elegant new ways of using Erlang to approach or solve a particular problem. The maximum length for the experience report is restricted to 2 pages.

3. Poster presentations describing topics related to the workshop goals. Each includes a maximum of 2 pages of the abstract and summary. Presentations in this category will be given an hour of shared simultaneous demonstration time.

Workshop Co-Chairs

Melinda Tóth, Eötvös Loránd University, Hungary
Scott Lystig Fritchie, Basho Japan KK

Papers must be submitted online via EasyChair (via the "Erlang2016" event). The submission page is https://www.easychair.org/conferences/?conf=erlang2016.

Submitted papers should be in portable document format (PDF), formatted using the ACM SIGPLAN style guidelines.

Each submission must adhere to SIGPLAN's republication policy. Violation risks summary rejection of the offending submission. Accepted papers will be published by the ACM and will appear in the ACM Digital Library.

Paper submissions will be considered for poster submission in the case they are not accepted as full papers.

The proceedings will be freely available for download from the ACM Digital Library from one week before the start of the conference until two weeks after the conference.

Erlang User Conference 2016

Erlang User Conference 2016

Erlang User Conference (EUC) is a two-day, multi-track event on Erlang programming language with elements of Elixir. We focus on real-world applications of Erlang, concurrency, distributed computing and scalability. We strive to bring together people passionate about Erlang and high-performance, massively scalable distributed systems.

Join us for a day of tutorials on 7 September and a two-day Conference on 8-9 September. This year we have also prepared very many training courses, check them out here.

OTP 19.0

Wed, 22 Jun 2016 00:00:00 GMT

Some highlights of the release are:

compiler, stdlib:
- New preprocessor macros ?FUNCTION_NAME, ?FUNCTION_ARITY
- New preprocessor directives -error(Term) and -warning(Term) to cause a compilation error or warning, respectively.

gen_statem a new state machine behavior
mnesia_ext: plugin of external storage solutions to mnesia
crypto: uses EVP interface in OpenSSL resulting in generally better performance and support for HW acceleration
ssh: performance improvements, uses the new gen_statem behavior
ssl: enhanced error log messages
dialyzer: the support for maps is very much extended both the type specification syntax and the type analysis.
erts:
- erlang:open_port(spawn, ...) 3-5 times faster
- tracing, extensive improvements (scalability, speed, match specifications on send/receive, support for lttng, ...)
- dirty schedulers improved
- per process configurable handling of message_queue
- fast loading of multiple modules
- max_heap_size process flag
erts/kernel:
- Experimental support for Unix Domain Sockets
  Example: gen_udp:open(0, [{ifaddr,{local,"/tmp/socket"}}])
and much more ....

Notes from OTP Technical Board

Wed, 18 May 2016 00:00:00 GMT

img src=http://www.erlang.org/upload/news/

The following decisions regarding EEPs (Erlang Enhancement Proposals) has been taken during the spring:

EEP-45 Function_Name and Function_Arity as macros

Approved

Already implemented and available in OTP 19.0-rc1.

EEP-44 Additional preprocessor directives

Partly Approved

Only the -warning and -error directives was approved and they are already implemented and available in OTP 19.0-rc1.

Some of the reasons for not approving the other directives in EEP-44 where:

Rather unclear what an OTP_RELEASE is and it will not be clearer as there are plans to split OTP in several parts.
Could lead to strange situations if these directives are combined with a package manager which also deals with dependencies.
Could lead to strange situations if testing for a version or existence of functions in non OTP modules.

In summary we where not convinced that the new directives will solve more problems than they might introduce. It is also already rather easy to create a preprocessor variable in the build-procesess that can be used in combination with -ifdef to achieve similar effects.
