I'm sponsoring this fasttrack for Raymond Xiong.  The release binding is
Minor, and the interfaces are Uncommitted.  There are man pages in the
materials directory.

======================================================================

Summary
=======

        This fast-track introduces Erlang/OTP R12B1 into SFW
        consolidation.

        Micro release binding is requested.

Discussion
==========

        Erlang is a general purpose programming language and
        runtime environment that has support for concurrency,
        distribution and fault tolerance. One of the fundamental
        properties and main strengths of Erlang is its built-in
        support for lightweight processes and message-passing
        style concurrency. Erlang is suitable for distributed,
        reliable, concurrent applications.

        OTP is a large collection of general libraries for Erlang.
        (OTP stands for Open Telecom Platform. The name was due
        to the fact that Erlang/OTP was originally designed for
        Telecom system).

        The latest version is R12B1, released on Feb 6, 2008.
        R12B1 means "Release 12B, patchlevel 1".

        All objects will be contained in /usr/erlang/$RELEASE,
        which has the following layout:

            /usr/erlang/$RELEASE
                |- bin
                |- lib
                |- man
                +- doc

        Note Erlang executables are actually in subdirs of
        /usr/erlang/$RELEASE/lib, and they will be linked
        symbolically from /usr/erlang/$RELEASE/bin and from
        /usr/bin. The latter links will always point to the
        highest $RELEASE of Erlang installed on the system.
        
        Because Erlang has large amount of man pages and html
        docs, a separated documentation package is proposed. So
        there will be two packages for a single Erlang release:

            SUNWerlang-$RELEASE
            SUNWerlang-$RELEASE-doc

        Take Erlang R12B1 for example, the package name will be
        SUNWerlang-r12b and SUNWerlang-r12b-doc. Files in these
        two packages will be installed under /usr/erlang/R12B,
        and symbol links will be created under /usr/bin to point
        to executables in /usr/erlang/R12B(since this is the
        the latest version for now).

	Doesn't this require a contract?  Did I miss seeing that in the
	materials?

Would more general SUNWerlang and SUNWerlang-doc package names
be better?

I don't see a need to track the version in the package names.
It looks like around four new versions of erlang are released
each year.

Jim,

Major new Erlang release came out every 1-2 years in the
past. I guess those versions you mentioned were patch releases.

Take R12B release as an example, it was first released on Dec
2007 as R12B-0. On Feb 2008, a new patch release R12B-1 was
released.

What I propose is to support multiple releases(ie., R11B, R12B)
and use the latest patch releases of them(ie., R11B-5, R12B-1).
For the purpose, separated package name and installation directory
is needed for each release. 

A brief introduction to Erlang/OTP versioning scheme can be
found here:

This may be ok, to maintain backwards compatibility. Do you see
a specific need to have older versions of erlang on a system
instead of just having the most recent version?

I don't have specific reason, but I observed other language(ie.,
Ruby, Java, Perl, etc.) were all packaged in this way. I think
it's good to have this flexibility?
 
Because Erlang/OTP R12B release is rather new, it is probably
not well tested and supported for some applications. For example,
below is from ejabberd README on which Erlang version to use:

  "Erlang/OTP R10B-9 up to R11B-5. Erlang R12 releases are not yet
   officially supported, and are not recommended for production
   servers"

There is such a thing as "too much rope".  There are significant
incompatibilities between versions of Java, and reasonable ones between the
two versions of Perl.  I can't speak for Ruby.  There are minor ones
between 2.3 and 2.4 of Python.  If released versions of Erlang are expected
to be incompatible, and flag-days aren't suitable for the customer base,
then two versions may be kept on the system.

Erm, perhaps this means that we shouldn't be delivering it, and using R11
for a while?

I think this is more of a timing thing. The ejabberd 2.0.0 release
was made 2/20/08 and the first Erlang R12 release was made 12/5/07,
and the second was made on 2/6/08. Depending on how they qualify
ejabberd releases, Erlang R12 probably wasn't an option in terms
of inclusion into their final test cycle. Erlang R11B-5 was released
1/13/07.

The ejabberd development version is now at 2.3.0, and is moving
faster than erlang. I don't see any major issues in the bugs or
logs with R12.

Raymond has the best experience to decide what versions of Erlang
and Ejabberd to use.

Are we sticking with the originally proposed versions?  I think this is the
only open question at the moment.

Yes. Raymond determined that Erlang/OTP R12B1 was the
best version to use, which was in the initial proposal.

Okay.  I'm marking this case as closed/approved, then.

Hi, Raymond,

I'm just interested are you using gcc/g++ or SunStudio compiler to build 
Erlang? If only gcc/g++ is able to build it, at least, GCC4SS could be 
used on SPARC platform.

Regards,

Yes, gcc/g++ only. The code cannot be compiled with SunStudio.

I think this is something that should be controled on sfw-gate
wide? 

# dmake -p | grep GCC
GCC= /usr/sfw/bin/gcc

If GCC4SS is believed stable and better on SPARC, I doubt why
not integrate it first?

Thanks,
Raymond

Hi, Raymond,

As far as I know, GCC4SS is much better than gcc/g++ (3.4.x) bundled in 
Solaris sfw. It uses SunStudio as the back-end to do the code 
generation. You may refer to the blog by alexey for the benchmark of 
gcc/gcc4ss/sunstudio, 
http://blogs.sun.com/alexey/entry/gcc_vs_gccfss_vs_studio.

PS., I assume that the code generator of gcc/g++ on x86 has comparable 
performance (or even better) with sunstudio. Maybe this the reason why 
there is no gcc4xs :)

Thanks for the information(I didn't know the wrapper before :)).
What I meant is that this is unrelated to Erlang/OTP integration.
SFW packages should be compiled with integrated tools, but is
gccfss available on default Solaris installation now? I don't
think so. If it is integrated in the future to replace the
current one, then it will be used automatically to compile Erlang.

Thanks,
Raymond

Folks, this isn't appropriate for the ARC case.  Please take it offline, or
move to sfwnv-discuss.

Thanks,

It depends, a lot of my code runs faster if compiled with Sun Studio.
This is why I prefer SS.

Just FYI that the FastTrack for Erlang/OTP will be updated to
include 64bit executables and libraries. The change was 
suggested during code review on sfw-discuss alias.

The new version is attached. The only change I made is that I
added the following new 64bit interfaces:

        /usr/bin/${MACH64}
                dialyzer         Uncommitted      Symbolic Link
                epmd             Uncommitted      Symbolic Link
                erl              Uncommitted      Symbolic Link
                erlc             Uncommitted      Symbolic Link

        /usr/lib/${MACH64}/erlang/  Project Private  Libraries and Binaries

Let me know if you have any concern or question.

Summary
=======

        Erlang[1] is a programming language and runtime
	environment designed for large-scale, fault-tolerant,
	distributed applications. One of its fundamental
	properties is its built-in support for lightweight
	processes and message-passing style concurrency.
	Erlang was originally designed for Telecom systems,
	but is also found very useful for network, database, 
	and other concurrent applications.

	OTP is a large collection of Erlang libraries to
	help people build applications. 

        This fasttrack introduces Erlang/OTP R12B1 into SFW
        consolidation.

        Micro release binding is requested.

Dependencies
============

	OpenSSL 0.9.7+	(snv_84 version 0.9.8a)
	jdk-1.2.2+	(snv_84 version 1.6.0)
	libgd		(snv_84 version 2.0.34)
