./lang/erlang, Concurrent functional programming language

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 21.0, Package name: erlang-21.0, Maintainer: pkgsrc-users

Erlang is a programming language which has many features more commonly
associated with an operating system than with a programming language:
concurrent processes, scheduling, memory management, distribution,
networking, etc.

The initial open-source Erlang release contains the implementation of
Erlang, as well as a large part of Ericsson's middleware for building
distributed high-availability systems.

Log message:
*: Move SUBST_STAGE from post-patch to pre-configure

Performing substitutions during post-patch breaks tools such as mkpatches,
making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.

lang/erlang*: Update to 21.0

Potential Incompatibilities
- All Corba applications are now moved from the OTP repository
- A new Corba repository will be created https://github.com/erlang
- New applications ftp and tftp, moved from inets
- ssl no longer supports 3_DES cipher suites or RSA-key exchange
  cipher suites by default
- Erlang:monitor on a primitive node (erl_interface, jinterface, etc)
  will no longer fail with badarg exception. Instead a monitor will be
  created, but it will only supervise the connection to the node.

- Enhanced IO scalability
- Support for usage of distribution controller processes for
  alternative transports, routing etc
- compact instructions on 64bit systems for code below 4GB 20% less
  memory for loaded code
- Rewrite of the efile-driver with NIFs and "Dirty schedulers"
  resulting in faster file operations
- non-smp VM removed
- link and monitor optimized for scalability
- os:getenv/putenv now work on thread-safe emulation. No longer in
  sync with libc getenv(3). Manual synchronization will be needed.

- Misc compiler optimizations including contributions from the Elixir
  team resulting in 10% improvements in benchmarks
- "Tuple calls" have been removed from the run-time system.
- Code such as f({ok, Val}) -> {ok, Val} is now automatically
  rewritten to f({ok, Val} = Tuple) -> Tuple. this reduces code size,
  execution time, and removed GC pressure.
- More information in stacktrace from a number of operators
- erlang:get_stacktrace/0 deprecated to be replaced with try ... catch
  C:R:Stacktrace -> ...
- Creation of small maps with literal keys optimized.
- A new predefined macro OTP_RELEASE and preprocessor directives -if
  and -elif

- DTLS is now supported in the SSL application
- Enhanced support for distribution over TLS
- "unsecure" ciphers removed from defaults in SSL and SSH.
- A new option value defined to facilitate implementing exec servers.
  Old option kept for compatibility, but now gives errors on stderror.

Standard libraries:
- New API for logging, logger
- New uri_string module for parsing URIs according to "The standard"
- New function lists:search(list,fun/1) -> {ok, Value} | false
- Changed default behaviour of .erlang loading. escript, erlc,
  dialyzer and typer no longer load an .erlang at all.

Log message:
lang/erlang: Update to 20.3.

- Added new API functions to facilitate cipher suite

erts, observer:
- More crash dump info such as: process binary virtual
  heap stats, full info for process causing out-of-mem
  during GC, more port related info, and dirty scheduler

- Add support for unix domain sockets in the http client.

erlang: Fix build with SunOS/C99.
   2017-12-13 15:45:20 by Filip Hajny | Files touched by this commit (8) | Package updated
Log message:
Update lang/erlang* to 20.2.

Some highlights:

crypto, ssl:
- The crypto API is extended to use private/public keys
  stored in an Engine for sign/verify or encrypt/decrypt
- The ssl application provides an API to use this new
  engine concept in TLS.

- SSH can now fetch the host key from the private keys
  stored in an Engine. See the crypto application for
  details about Engines.

- A new command line option -ssl_dist_optfile has been
  added to facilitate specifying the many options needed
  when using SSL as the distribution protocol.

- Improve performance of the new string functionality
  when handling ASCII characters.
