>68 OS Papers (OO?)

			THE PAPER TRAIL

The "Paper Trail" - an experimental database of ftp'able OS papers
is now available through http://pclsys64.dcrl.nd.edu/papers. This
database allows users to find and access papers that are available for
ftp on the internet. We have initially populated this database with
about 5500 entries. Most of these entries reflect our own area of
interest, that is Operating Systems and related areas. We'll add
entries to the database from time to time. However, it'll probably
be very difficult to keep this up-to-date without help from other
users of this database. Hence, the database provides any user the added
facility to submit entries.

We hope that the xmosaic interface to this database is intuitive and
simple. If you have any suggestions and criticisms, please do let us
know - including how this compares with other such services.

>69 Trellis

From: bruno@tk.telematik.informatik.uni-karlsruhe.de (Bruno Achauer)
Subject: Trellis compiler available
Date: 23 Oct 1994 00:16:02 GMT
Organization: Telematics Department, Karlsruhe University, Germany

The beta release of version 0.2 of the TNT Trellis system is now
available for anonymous ftp from tk.telematik.informatik.uni-karlsruhe.de.

Enclosed is ANNOUNCE file from the distribution:

What are Trellis and TNT
~~~~~~~~~~~~~~~~~~~~~~~~

Trellis is an object-oriented language developed within Digital
Equipment Corp. The language features compile-time type checking,
multiple inheritance, parametrized types, exception handling and
iterators.


TNT is a new implementation of Trellis, consisting of a compiler, a
library of predefined types and a (rudimentary) run time system:

  - The compiler implements the language as defined by the reference
    manual (except for a few esoteric constructs), plus a few minor
    extensions.

  - Predefined types are standard types such as integers, strings,
    arrays etc. (in Trellis, no type is built into the language!),
    an IO system and a (rudimentary) hierarchy of collection types.

  - The run time system is pretty incomplete right now; in particular,
    neither garbage collection nor threads are implemented yet.

The system is available for several architectures:

  - the Digital Alpha (running OSF/1),
  - the HP Precision Architecture (under HP-UX),
  - the Intel 386 (under Linux),
  - Digital's Mips workstations,
  - Sun's Sparc workstations (running SunOS).

Both source code and prebuilt kits are available.

Further work will concentrate on supporting transparently distributed
objects a la DOWL.


Changes since last version
~~~~~~~~~~~~~~~~~~~~~~~~~~

* The HP-PA, Linux and Sparc ports.

* Building the compiler no longer requires the SFIO library.

* The compiler now can use the GNU assembler to generated object files;
  at least on small MIPS machines, this will speed up compilation
  considerably.

* Several minor bugs have been fixed.


Requirements
~~~~~~~~~~~~

The prebuilt kits require disk space ranging from 800 KB (Linux) to
2.4 MB (OSF/1); a C compilation system (assembler, linker and the C
library) must be installed. In addition, the Mips and HP-PA versions
will benefit if the GNU assembler is present.

Building the system from scratch requires from 5.2 MB (Linux) to 16 MB
(Alpha). You will also need some auxiliary tools and libraries:

  - Cocktail V9208 (the Karlsruhe Compiler toolbox),
  - GNU make V3.68 or later,
  - patch,
  - makedepend.

Most of these should be available on a nearby ftp site (makedepend is
part of the X distribution; GNU make and patch are distributed by the
FSF).

Cocktail is available from several ftp sites, but most of the versions
floating around will not work on the Alpha. A patched version is
available on tk.telematik.informatik.uni-karlsruhe.de (see below).

If you plan to build the MIPS or the SPARC version, you will also need
the GNU C compiler.


How to get it
~~~~~~~~~~~~~

A source kit is available via anonymous FTP from

    tk.telematik.informatik.uni-karlsruhe.de (129.13.3.200)
    file directory /pub/tnt/tnt-0.1.tar.gz.

There are also some additional kits in the same directory:

    * doc	-- PostScript versions of DEC-TR-372 (language
		   reference manual) and DEC-TR-373 (language primer).

    * prebuilt	-- binary kits.

    * tools	-- source kits for Cocktail.


Please direct bug reports, requests, comments etc to

    tnt@tk.telematik.informatik.uni-karlsruhe.de.

>70 CooL-SPE

From: Gerhard.Mueller@sietec.de (Dr. Gerhard Müller)
Subject: Announcement of the CooL Software Production Environment
Date: Tue, 25 Oct 1994 11:42:28 UNDEFINED
Organization: Sietec Systemtechnik

		ANNOUNCEMENT

The CooL-Software Production Environment - a new object-
oriented development environment in Public Domain

The CooL-SPE is a modern software production environment 
for the development of object-oriented application systems 
supporting grafical user interfaces and relational database 
technology. In the landscape of existing software production 
technologies the CooL-SPE is more closely settled to 4GL 
environments than to the usual C++ environments, mostly 
more dedicated to system programming. The CooL-SPE was 
developed by Siemens Nixdorf Informationssysteme (SNI) 
within the ESPRIT project ITHHACA and is used since in a 
number of large projects.

Allthough the CooL-SPE as a programming environment is 
functional quite rich, it is also very lean and thus comparable 
fast to learn and reliable tu use. In one project, which we sup-
ported recently, we could learn that newly assigned engineers 
to a fairly large project (400 classes with some 100.000 lines 
of code) were able to learn the environment, to understand the 
application and to become productive within a month - and 
that without any practical experience on object-oriented pro-
gramming before.

The system has product quality and is implemented in major 
parts in itself.

The CooL-SPE is available for Linux 1.0.1, Solaris 2.3 and 
SINIX 5.41. You may receive the system (sources and docu-
mentation) via ftp.fu-berlin.de in the directoy /pub/unix/lan-
guages/cool.The file itself is named cool-2.1.tar.Z.

                            Giuseppe Castagna

is available by anonymous ftp at ftp.ens.fr in the file
 /pub/reports/liens/liens-94-18.A4.dvi.Z

ADVERTISEMENT: This paper tries to explain
-------------

1. What covariance and contravariance serve for.

2. Why covariance and contravariance are not opposing views but both
   *must* be integrated in a *type-safe* formalism. I.e.: don't choose
   just one of them.

3. Where the "objects as records" analogy hides covariance.

4. How to type binary methods in the models based on the analogy "objects
   as records" (i.e. how to have ColorPoint < Point even if they respond
   to a message "equal")

5. How to have multiple dispatch when objects are modeled by (recursive)
   records.

6. Why all the previous points are strictly related one to each other.
 
                                 ABSTRACT

In type theoretic research on object-oriented programming the ``covariance
versus contravariance  issue'' is a  topic of continuing  debate.  In this
short note  we   argue that covariance  and   contravariance appropriately
characterize  two distinct  and  independent  mechanisms.    The so-called
contravariance  rule correctly captures   the {\em  substitutivity\/},  or
subtyping relation (that establishes which  sets of codes can replace {\em
in every context\/} another   given set).  A covariant relation,  instead,
characterizes the {\em specialization\/} of  code (i.e.\ the definition of
new code that replaces   the old one  {\em  in some particular  cases\/}).
Therefore,  covariance  and contravariance  are  not  opposing  views, but
distinct  concepts that each have   their place in object-oriented systems
and that  both   can  (and  should)  be type    safely  integrated in   an
object-oriented language.

We  also show  that   the  independence of    the two  mechanisms  is  not
characteristic of  a  particular model  but is  valid  in  general,  since
covariant specialization is present also  in  record-based models, but  is
hidden by a deficiency of all calculi that realize this model.

As an aside, we show that  the lambda&-calculus can  be taken as the basic
calculus both for an  overloading-based and for  a record-based model.  In
that  case, one not only obtains  a more uniform vision of object-oriented
type  theories but, in   the case of  the  record-based approach, one also
gains  multiple dispatching,  which   is  not  captured by   the  existing
record-based models.

>74 TRILLIUM (CMM)

From: fcoallie@qc.bell.ca (Francois Coallier)
To: ami@aut.alcatel.at
Subject: TRILLIUM Release 3.0 available.

Dear Colleagues,

The release 3.0 of the TRILLIUM Model is now available
through the Internet.

The TRILLIUM model is a software product development and
support capablity model based on the SEI's Capability
Maturity Model (CMM).

TRILLIUM differs from the CMM in its roadmap structure and
its product and customer focus.

This release of TRILLIUM is substancially different from
2.3d:

   1) The introductory chapters explaining the model and its
      application have been extensively rewritten and expanded.

   2) Practices are updated to provide 100% coverage of the CMMM
      version 1.1, ISO 9001:1994 and ISO 9000-3, and Bellcore TR-
      NWT-000179.

   3) Traceability tables to external source documents are
      generated automatically.  The verification of all references
      is thorough.

   4) The glossary has been updated.

The TRILLIUM model is in the public domain.  Copies (as a series of
uuencoded Poscript files) are distributed freely through the Internet.

To receive your copy via E-Mail, all you have to do is to send me a
request with your complete coordinates.

Bounded hard copies are available from the Bell Canada Acquisitions
department.  Pricing and shipping information are available on
request (Sorry: this is purely for budgetary reasons).

Cecil is a new purely object-oriented language intended to support
rapid construction of high-quality, extensible software. Cecil
combines multi-methods with a classless object model, object-based
encapsulation, and optional static type checking.

Ongoing research in the Cecil project is in two major areas: language
design issues and type systems for languages like Cecil, and
implementation research on making languages like Cecil run faster.

Ongoing research in the Cecil project is in two major areas: language
design and object-oriented language implementation.  Our language
design research addresses modules and typechecking for multi-method
based languages, and language mechanisms for implicit object
classification.  Our implementation research is exploring a variety of
optimization techniques for object-oriented languages, including
profile-guided type feedback, whole program analysis, specialization,
and interprocedural type inference algorithms.

Further information about Cecil is available from our WWW site:

  http://www.cs.washington.edu/research/projects/cecil/www/cecil-home.html

Papers about Cecil are also available via anonymous ftp from cs.washington.edu
in the directory /pub/chambers.  See the README file in that directory for a
description of the available papers.

Check out our WWW site: we'd appreciate any feedback people might have.

[...]

Producing readable, on-line text versions is difficult, because the
papers contain embedded figures and formatted text.  Many of the
papers are available as UW CSE Technical reports, however.  Full
details can be via anonymous ftp in:
  cs.washington.edu:/pub/chambers/README.

Hard-copies of the technical reports may also be requested via
electronic mail. Send email to: tr-request@cs.washington.edu. Orders
will be filled via surface mail, subject to availability. Please be
sure to include a complete snail-mail address with your request.

As for the compiler, we plan to have an initial release to "friendly,
interested parties" sometime in the first half of 1995.  The release
will include full source code for the compiler (currently about 45,000
lines of Cecil code), and will include both a C-code based back end
(for portability) and a native Sparc back end.

We're maintaining a list of people who are interested in this initial
release.  If you would like to be added to this list, send e-mail to
me (jdean@cs.washington.edu).

The C++ standard draft includes the spec for Standard Template Library

out the C++ faq (somewhere under ftp://rtfm.mit.edu/...) for where to
find it. If you're using GNU C++ 2.6.3 (or a more recent snapshot), the
hacked version of STL that comes with libg++-2.6.2 (or w/today's 2.6.9
snapshot) is quite usable. ObjectSpace and Modena are two vendors selling
STL implementations that cover a wide variety of compiler/platform combos
(info@objectspace.com, 1-800-MODENA-1 for more info). Also welcome to
take a look at my STL newbie file (http://www.xraylith.wisc.edu/~khan/
and follow the 'STL Newbie doc' link). If you're using Borland 4.5 on a

Announcing:

	Phantom, an Interpreted Language for Distributed Programming

This message is an announcement for the Phantom home page, mailing list,
and prototype interpreter for the centralised language core.

-------------------------------------------------------------------------------
>From  the Phantom home page:

What is Phantom?

Phantom is a new interpreted language designed to address some of the problems
presented by large-scale, interactive, distributed applications such as
distributed conferencing systems, multi-player games, and collaborative work
tools. Phantom combines the distributed lexical scoping semantics of Obliq with
a substantial language core. The language core is based on a safe, extended
subset of Modula-3, and supports a number of modern programming features,
including:

   * static structural-equivalence typing
   * objects
   * modules and interfaces
   * lightweight threads
   * exceptions
   * garbage collection
   * higher-order functions and lambda expressions
   * a keyword binding mechanism

>81 Java (Distr Prog)

This recent article discusses and quotes Java.

From: Greg Wilkins <gregw>
Newsgroups: comp.object
Subject: Java vs. C++
Date: 25 May 1995 03:42:36 GMT
Organization: Telstra Corporation

I have been reading about the Java language from Sun Labs:
  http://java.sun.com/index.html

The way I use C++ looks like it would transfer to Java
very easily, giving me access to the featurs of C++ I
like, without the danger of the many extra C++ "features."

I'm interested in hearing opinions on Java from the many 
posters that dislike C++.   While the chances of a new 
language taking off are very very slim, looking at
languages like Java are good ways of refining the way
we learn/teach/review/use languages like C++.

Just to steal a bit of the Java doco:


     Java: A simple, object-oriented, distributed, 
           interpreted, robust, secure, architecture neutral, 
           portable, high-performance, multithreaded, 
           and dynamic language.


We wanted to build a system that could be programmed easily without a lot of
esoteric training and which leveraged today's standard practice.
Most programmers working these days use C, and most programmers doing
object-oriented programming use C++. So even though we found
that C++ was unsuitable, we designed Java as closely to C++ as possible in
order to make the system more comprehensible.

>82  Reflection Paper

>Curious what you mean by "reflective" design?

Reflection is the ability to change aspects of the implementation of a
language (eg. method dispatch, memory allocation, synchronization
policies), on a per-object (or per-class) basis.

For example, reflection can be used to add distributed message passing to a
language that doesn't have this hard-wired into the compiler, simply by
changing how method dispatch is implemented for remote objects.

A typical (but not the only) model of reflection has a 'meta-object'
associated with each object. There is a default meta-object which defines the
basic capabilities of the language (in practice, calls to this are usually
inlined). The code emitted by the compiler for operations like method
dispatch, etc. is modified to check whether the object in question is
reflective (has a meta-object other than the default).

So, the code for a method call
    "receiver.method (param1, param2, ...)"
might look something like:

if (receiver is non-reflective)
    inline code for a standard method call
else
    m := the meta-object for receiver
    m.perform (receiver, method_id, parameter-list)

m can also be reflective (which leads some research papers to talk about an
infinite tower of objects and corresponding meta-objects), but normally only
one or two levels are used.

The meta-object can implement dispatch however it likes, for example using
RPC to a distributed object, or whatever. The interface of a meta-object
(which includes 'perform' in this case) is called the meta-object protocol.

Other applications of reflection include:

- memoized calls
  (the result of a function call is cached, for use on subsequent calls with
  the same parameters)
- future objects
  (an object is calculated in a parallel thread; any access to the object
  blocks until it is ready)
- transaction messages
  (as used in ODBMSs)
- asynchronous messages
  (as used in Actor languages)
- interfaces to other languages and type systems
- implementation of garbage collection
- heaps optimized for different granularities of object
- persistence
- checkpointing
- replication

and so on.

                  OZ++ System, Version 1, Release 2

                            Release Notes

 Tsukuba Research Laboratory Of Open Fundamental Software Technology

Copyright (c) 1994 Information-Technology Promotion Agency, Japan (IPA)

All rights reserved.  No guarantee.  
This technology is a result of the Open Fundamental Software Technology
Project of the Information-Technology Promotion Agency, Japan (IPA)

   This document  describes  the  objectives  and  the  configuration  of  this
software and the features of this release.
   Details  on  the  copyrights  of  this  software  are  described in the file
'COPYRIGHT'.

1. What is OZ++ ?

   In the software industry, people throughout the world have been  continually
developing  software  with  very  similar  features;  and thus "reinventing the
wheel" as it were.  Such  redundancy  has  been  impeding  the  improvement  of
software  productivity and reliability. Therefore, the sharing and distribution
of not only information but also of software is needed over the  network  (i.e.
Internet).  However,  this  cannot  be  achieved  merely by opening the network
infrastructure and making software publicly available.

   The OZ++ system has therefore  been  developed  to  solve  this  problem  of
software transfer.  Based on the concept of object-orientation, the OZ++ system
provides distribution, upgrading, and authorization function of  software  over
the network. The high modularity of object-oriented systems and the conformance
checking  of  interface  between  objects  promotes  the  re-using  of software
components.  The infrastructure is now being put into place so that  components
of different software products can be combined in much the same way as hardware
products.  Because the OZ++ systems enables the distribution of software  (i.e.
program),  software  can  be  brought  from all over the world; furthermore, it
allows such software to  run  without  complicated  installation.  Because  the
versions  of  software  are automatically recognized by the system, old and new
versions are available at the same time and the newer version is  automatically
distributed.  In  addition,  validation functions have been included to confirm
the source of the software so that everyone can use it without  worrying  about
viruses.  Because  of these functions, OZ++ system users are always able to use
the newest and most appropriate types of software available.

2.The configurations of the OZ++ system

   In OZ++, the computation takes place by  communicating  distributed  objects
placed  over  the network. Objects are run on processes called executors.  An
executor can run an arbitrary number of  objects  and  is  managed  by  process
called  'nucleus'.  Each  station  is always managed by a nucleus and a nucleus
can manage an arbitrary number of executors.

   See README.first for how to install and startup the OZ++ system.

3. About this release

   This release contains the following:

*Nucleus
*Executor
*Launcher
*Compiler-front-end
*Object-images for demonstration

   By this release you can you can compile and execute OZ++ program.

   To compile your OZ++ program, you  can  use  the  `compiler-front-end'.  How
to use of it is described in the file doc/README.compile.

   To  execute  your  OZ++  program, you can use the `launcher'.  How to use of
it is described in the file doc/README.launcher.

   To create new object image, a tool called `newimage'  is  provided.  How  to
use of this tool is described in the file doc/README.newimage

   Furthermore, you can see two kind of demonstrations of the OZ++ system:

*Application 'Encyclopedia'

Showing the method invocations between remote stations.

*Application 'Object mail system'

Showing where a  new  version  of  a  program  is  automatically  selected  and
distributed.
   A tutorial of these demonstrations is provided in doc/DemoTutorial.

   The Release schedule for future versions is as follows:

*Release 3

Around 6/20.  You can compile, manage, and run OZ++ programs distinguishing its
versions.  The first version of debugger will be included.

>84 OOA/D Example, Java

From: Rick van Rein <rick@iconcomp.com>
Newsgroups: comp.object, comp.lang.java
Subject: Full OOA&D example now has Java Implementation
Date: Wed, 07 Feb 1996 16:53:38 -0600
Organization: ICON Computing, Inc.

Hello All,

Some time ago we anounced a full example of OOA&D to be available on our
web site. We are pleased to inform you that the Java implementation is
now also available.

The exercise available is a small Telephone Switch system, of which the
Java/AWT GUI on a Netscape browser provides an excellent means of
getting a feel for the application's workings. This is likely to be of
great use in understanding the models built during analysis and design.

The example is available on:

        http://www.iconcomp.com/demo/case-Phone/phoneCase.html

and the implementation in Java can be accessed by clicking on
'Implementation'.

Have fun with it,

>86 OODB Driver

How many drivers do you put on your client to simultaneously access: 

  Oracle 
  Sybase 
  Informix 
  uniVerse 
  Ingres 
  ISAM 
  DB2 

And how many more do you add when you have on the same client: 

  Smalltalk apps 
  Visual Basic apps 
  Visual C++ apps 
  Java applets 

How would you like to have one database driver that is free that you can
download off the Internet? And how would you like that driver to be a Web
development kit so that any data you access from your OO apps can be brought
up simultaneously as a Web database server? 

If you are a developer that has any variation of these problems you owe it
to yourself to take a look at a product that was just announced today: 

  http://www.vmark.com/news/preleases/presrel21.html 

This is object-oriented middleware built in C++ that does true object passing
between the database and application environments. The guy the engineered it
wrote the first CORBA spec for the OMG (although this particular product is
engineered for high performance DB access and not CORBA). 

It's taken six months to convince VMARK to put this on the net for free. It
is the real stuff and is used in large production sites worldwide. For
example, the Kew Royal Botanical Gardens serves the net using this middleware:
