2 Arjuna (Distr Prog System)

What: Release 2 of Arjuna Distributed Programming System From: arjuna@newcastle.ac.uk (Arjuna Project) Date: Mon, 17 May 1993 12:37:34 GMT We are pleased to announce the availability of a new version of Arjuna: a programming system for reliable distributed computing, and the Arjuna mailing list. The software and the manual for the Arjuna system can be obtained by anonymous ftp: arjuna.ncl.ac.uk (128.240.150.1) Arjuna System This beta release of ArjunaPR2.0 fixes all known bugs present in ArjunaPR1.2B that have been reported to us or that we have found, and contains only minimal information about how to use the new features provided. This release should be compilable with the following compilers: AT&T Cfront Release 2.1, on SunOS 4.1.x, (using Sun supplied lex and yacc). AT&T Cfront Release 3.0.1, on SunOS 4.1.x and Solaris 2.1, (using Sun supplied lex and yacc). GCC versions 2.1, 2.2.2, on SunOS 4.1.x, (using flex(v2.3.x) and bison). Patched GCC version 2.3.3 on SunOS 4.1.x and Solaris 2.1, (using flex(v2.3.x) and bison). Sun C++ 2.1, on SunOs 4.1.x, (using Sun's lex++ and yacc++). HP C++ (B2402 A.02.34), HP-UX 8.07, (using HP supplied lex and yacc or lex++ and yacc++). The major new features are: - Faster object store. - Support for replicated objects. - Memory resident object store. - Support for ANSAware (not available via ftp) Arjuna supports nested atomic actions (atomic transactions) for controlling operations on objects (instances of C++ classes), which can potentially be persistent. Arjuna has been implemented in C++ to run on stock platforms (Unix on SUNs, HPs etc). The software available includes a C++ stub generator which hides much of the details of client-server based programming, plus a system programmer's manual containing details of how to install Arjuna and use it to build fault-tolerant distributed applications. The software and the manual can be obtained by anonymous ftp: arjuna.ncl.ac.uk (128.240.150.1) Several enhancements and ports on various distributed computing platforms are in progress. We would be pleased to hear from researchers and teachers interested in using Arjuna. The programmer's manual contains the e-mail addresses for sending your comments and problem reports.

3 BOS (prototyping)

What: BOS From: Sean.Levy@cs.cmu.edu Date: 23 Apr 92 18:07:32 GMT [For readers of comp.object and self-interest, BOS is a prototype-based object system that I have, er, prototyped in Tcl. It is available via anon FTP to monch.edrc.cmu.edu under /usr0/snl/archive/bos-1.2.tar.Z (you have to cd to /usr0/snl/archive first and then get the file, due to CMU security hacks in ftpd). I thought that this would be of interest to comp.object and self-interest, so I'm cross-posting/mailing --S] Note: I play very fast and loose with the terminology of OOP to get my point across. I apologize if I offend any sensibilities, and will clarify what I say if it is obfuscated by my use of terms.

6 FMPL (prototyping)

What: Interpreter for FMPL of Accardi, Release 1 From: blojo@xcf.berkeley.edu (Jon Blow) Date: 2 Jun 92 08:42:26 GMT An interpreter for FMPL of Accardi, Release 1 is now available for ftp at xcf.berkeley.edu:src/local/fmpl/. *FMPL is a prototype-based object-oriented programming language. *FMPL possesses lambda-calculus based constructs. *FMPL is an event-driven language; the events it responds to are mainly based on the behavior of input/output streams, not only within the unix domain but across the internet as well. *FMPL supports "pretty"-printing of internally-represented code back into readable form. *FMPL is an experimental language developed at the Experimental Computing Facility of the University of California, Berkeley. This release is something of a beta test since the language has not been widely used outside Berkeley. It is hoped that this release will draw useful comments and suggestions from the world at large that will help in improving future versions of FMPL.

7 MAX (visual OO)

From: fingerhu@ircam.fr (Michel Fingerhut) Subject: IRCAM DSP software for DEC/ALPHA and DEC/MIPS Organization: Inst. de Recherche et Coordination Acoustique/Musique, Paris Date: Fri, 13 Aug 93 11:25:23 GMT ftp.ircam.fr:/pub/IRCAM/programs contains some of the IRCAM-developed software packages (in demo version; see further down for availability of the fully functional versions), including runnable binaries for both the DEC/ALPHA (osf1) and DEC/MIPS (ultrix) architectures, and soon available on other platforms (SGI and Macintosh). MAX MAX is a visual, object-oriented, programming language, initially designed for interactive musical performance, but which is suitable for digital signal processing as well as real-time control. It allows interconnecting of oscillators and filters, building custom controller modules and simulation units all from a core collection of signal processing objects. First developed by Miller Puckette at IRCAM in late 1986 to control the IRCAM 4X, it was later implemented on the Apple Macintosh as a graphical programming environment for MIDI applications. This version has been extended by the Opcode company in Palo Alto, CA (USA), and is available through them. The Alpha version (and its demo-only subset) is based on the NeXT version, where it is used to control the IRCAM-designed ISPW board. This card, based on two Intel i860 microprocessors, handles numerically-intensive real-time operations. To date, it has been extensively used in live performance of full-length musical compositions (see some references in the MAX/doc directory), as well as in scientific and experimental applications requiring real-time control. SVP SVP (``Super Vocodeur de Phase'') is a signal processing tool which was designed and developed at IRCAM by Gilles Poirot and Philippe Depalle. It is a full system for the analysis and synthesis of sound, whose core is a phase vocoder, and which comprises several modules for analysis (FFT, LPC..), filtering (band modes, surface modes...), time- scaling, mixing, spectral combination, cross-synthesis and amplification, which can be combined in multiple ways. UDI UDI is a library of C routines which provides a coherent software approach for developing and maintaining digital signal processing algorithms on stand-alone workstations or on host/array processor configuration. Initially designed for sound signal analysis and synthesis, it can be used by any application which does vector math calculation. It provides functions ranging from elementary vector and matrix operations to more specific DSP operations, such as, but not limited to, FFT, least-square, linear prediction coding, discrete cepstrum and pitch detection. UDI was actually used in implementing SVP. HOW TO RETRIEVE The following example contains underlined text.

8 O'small (OO lang for teaching)

From: hense@sol.cs.uni-sb.de (Andreas Hense) Subject: *** NEW O'small compiler available by ftp !!! *** Date: 25 Jun 1993 13:54:35 GMT Organization: Universitaet des Saarlandes,Rechenzentrum O'small - THE object-oriented language for teaching --------------------------------------------------- (Announcement of a new compiler) *** An object-oriented language for teaching? Depending on which aspects of object-orientation you want to convey you may choose your teaching language. If you want to teach the aspect of software reuse and nice graphical user interfaces, you should choose Smalltalk. If you want to show students how to program in a best selling language you should choose C++. *** In which case should I choose O'small? You should consider O'small if you believe that computer languages should have a GOOD FORMAL SEMANTICS. Everyone will agree that a language needs a formal semantics. Otherwise, your program will yield different results on different implementations. A good formal semantics does not only serve the purpose of precisely defining what the results of your programs are, it also gives insights about the nature of the language. You should consider O'small if you do not want to waste time on unnecessary details. O'small is CONCISE. Its syntax and semantics takes no more than one page (if you choose the right font). Its syntax is similar to more traditional languages. O'small has been used in a lecture showing the differences between wrapper semantics (denotational) and method lookup semantics (operational). O'small is FREE! Up to now, there has only been an O'small interpreter written in Miranda [Hen91b]. This interpreter is directly based on the denotational semantics of O'small [Hen91d]. The interpreter itself is available by ftp. However, you need Miranda in order to run it. Now, there is a NEW IMPLEMENTATION of O'small based entirely on EASILY AVAILABLE SOFTWARE. This software is not free but it does not cost anything. The new implementation is based on an abstract machine [Boe93]. You can MODIFY the language and have your students make experiments with it. The source code of the abstract machine and the specifications for the parser and scanner generators are available. Using these generators you can make experiments for your own research in statical analysis of object-oriented languages. *** I would like to TRY O'small You get the implementation by anonymous internet ftp. The following table gives the ftp connection information.

9 OBJ3 (OO lang)

What: Release 2.0 of OBJ3 (needed for FOOPS and OOZE, concurrent OOP) Date: Thu, 4 Jun 92 15:07:26 BST From: Paulo.Borba@prg.oxford.ac.uk OBJ is available from SRI, see the message below; prototypes implementations of FOOPS (without the concurrent extension) and OOZE are due to the end of the year, but for both you also need OBJ. Unfortunately, I don't have any document about the FOOPS extension now, but probably by the end of the year. I will send it to you as soon as possible. What: Release 2.0 of OBJ3 is now available From: winkler@csl.sri.com (Timothy Winkler) Date: 6 Apr 92 08:35:40 GMT Release 2.0 of OBJ3 is now available! Improvements in this version include some language extensions and additional theorem proving features. In addition, an effort has been made to speed up the implementation; rewriting is often twice as fast as in the original implementation. We are including the AKCL patches from the University of Texas at Austin in the distribution, which are necessary for maintaining the portability of OBJ3 and also improve its efficiency. In addition, we are distributing a SPARC version of OBJ3. OBJ3 has pattern matching modulo associativity, commutativity, and identity. New: the system automatically computes conditions for rules involving matching modulo identity that are used to prevent obvious non-termination problems. Also new to this version of OBJ3 is a facility for controlled rewriting. This provides substantially increased support for the use of the system for equational theorem proving. To receive the OBJ3 distribution tape or an OBJ3 license, send a request to: Judith Burgess (OBJ3) Computer Science Laboratory SRI International 333 Ravenswood Ave. Menlo Park, CA 94025-3493, USA Telephone: (415) 859-5924 Fax: (415) 859-2844 email: obj3dist@csl.sri.com Be sure to give us your postal mailing address. Then we will send you the OBJ3 Information Form, and License Agreement, with instructions on how to fill them out. (A KCL license form will also be included.) When you return them to us, appropriately filled out and signed, we will send you the tape, somedocumentation, and, in case you are requesting a tape, an invoice for $150.00 plus any required taxes. If you already have an OBJ3 license, then you don't need to get a new license, but, if you are requesting a tape from SRI, you are asked to pay the above distribution fee. It is also possible to get a license for OBJ3 at no charge from SRI and then get the OBJ3 distribution itself from some third party also having a license.

11 OOT (OO Turing demo)

What: OOT From: holt@turing.toronto.edu (Ric Holt) Date: 26 Apr 93 20:14:43 GMT OBJECT ORIENTED TURING: DEMO AVAILABLE VIA FTP OOT (Object Oriented Turing) is a programming language that has been developed at the University of Toronto. An OOT demo, which includes the fully implemented language, is available for Sun/4's running X windows. See below for instructions to copy the demo to your site. OOT supports the standard OOPL features of information hiding, classes, polymorphism and generics, as well as the usual features in C and Pascal style languages. It also supports concurrency, exception handling and system programming (pointer arithmetic, bit manipulation, etc). The OOT environment is designed for teaching Computer Science. It is being used in introductory programming courses, courses on OO concepts, compiler courses, OS courses, etc. The OOT environment is fully integrated, with multi-window editing, turbo speed compiler, integrated color graphics, GUI user interface, implicit MAKE, on-line manual, integrated demos, etc. The system includes an experimental CASE tool with an interface browser and a visual system browser.

12 Sather (simple Eiffel)

What: SATHER Sather is under development at the International Computer Science Institute. Sather has clean and simple syntax, parameterized classes, object-oriented dispatch, multiple inheritance, strong typing, and garbage collection. The compiler generates efficient and portable C code which is easily integrated with existing code. The initial beta test release of the language was in May, 1991. The compiler, debugger, Emacs development environment, documentation, and library classes are available by anonymous ftp from "icsi-ftp.berkeley.edu". "sather@icsi.berkeley.edu" is a mailing list for discussing aspects of Sather and "sather-admin@icsi.berkeley.edu" should be used for bug reports and requests to be added or deleted from the mailing list. Sather is based on Eiffel but is more concerned with efficiency and less with some of the formal and theoretical issues addressed by Eiffel. The language is much smaller than the current Eiffel, it eliminates over 40 keywords and simplifies the syntax and inheritance rules. Like Eiffel, Sather code is compiled into portable C and efficiently links with existing C code. The Sather compiler is written in Sather and has been operational for almost a year, though it is still being improved. Preliminary benchmarks show a performance improvement over Eiffel of between a factor of 4 and 50 on basic dispatching and function calls. On the benchmarks used at Stanford to test Self (including 8 queens, towers of hanoi, bubblesort, etc), Sather is even slightly faster than C++. The Sather compiler and libraries are publicly available under a very unrestrictive license aimed at encouraging contribution to the public library without precluding the use of Sather for proprietary projects. The goal is to establish a repository for efficient, reusable, well written, publicly available, classes for most of the important algorithms in computer science. There are currently about 120 classes in the library. The libraries are growing quickly and will collect together classes from many authors under the same unrestrictive license. A GNU emacs development environment for Sather is available. A debugger based on gdb from the Free Software Foundation is also available. A parallel version of Sather for shared memory machines called "Psather" is also under development. From the Sather FAQ, August 16, 1993 (See Section 1.24): Q 1: What is Sather? ~~~~~~~~~~~~~~ Sather is an object oriented language which aims to be simple, efficient, interactive, safe, and non-proprietary. It aims to meet the needs of modern research groups and to foster the development of a large, freely available, high-quality library of efficient well-written classes for a wide variety of computational tasks. It was originally based on Eiffel but now incorporates ideas and approaches from several languages. One way of placing it in the "space of languages" is to say that it attempts to be as efficient as C, C++, or Fortran, as elegant and safe as Eiffel or CLU, and to support interactive programming and higher-order functions as well as Common Lisp, Scheme, or Smalltalk. Sather has garbage collection, statically-checked strong typing, multiple inheritance, separate implementation and type inheritance, parameterized classes, dynamic dispatch, iteration abstraction, higher-order routines and iters, exception handling, assertions, preconditions, postconditions, and class invariants. The development environment integrates an interpreter, a debugger, and a compiler. Sather code can be compiled into C code and can efficiently link with C object files.

13 Self

From: hoelzle@Xenon.Stanford.EDU (Urs Hoelzle) Subject: Announcing Self 3.0 Date: 28 Dec 93 22:19:34 GMT ANNOUNCING Self 3.0 The Self Group at Sun Microsystems Laboratories, Inc., and Stanford University is pleased to announce Release 3.0 of the experimental object-oriented programming language Self. This release provides simple installation, and starts up with an interactive, animated tutorial. Designed for expressive power and malleability, Self combines a pure, prototype-based object model with uniform access to state and behavior. Unlike other languages, Self allows objects to inherit state and to change their patterns of inheritance dynamically. Self's customizing compiler can generate very efficient code compared to other dynamically-typed object-oriented languages. The latest release is more mature than the earlier releases: more Self code has been written, debugging is easier, multiprocessing is more robust, and more has been added to the experimental graphical user interface which can now be used to develop code. There is now a mechanism (still under development) for saving objects in modules, and a source-level profiler. The Self system is the result of an ongoing research project and therefore is an experimental system. We believe, however, that the system is stable enough to be used by a larger community, giving people outside of the project a chance to explore Self. 2 This Release This release is available free of charge and can be obtained via anonymous ftp from Self.stanford.edu. Also available for ftp are a number of published papers about Self. There is a mail group for those interested in random ramblings about Self, Self-interest@Self.stanford.edu. Send mail to self-request@self.stanford.edu to be added to it (please do not send such requests to the mailing list itself!). 2.1 Implementation Status Self currently runs on SPARC-based Sun workstations running SunOS 4.1.x or Solaris 2.3. The Sun-3 implementation is no longer provided. 2.2 Major Changes Below is a list of changes and enhancements that have been made since the last release (2.0.1). Only the major changes are included. o The graphical browser has been extended to include editing capabilities. All programming tasks may now be performed through the graphical user interface (the "ui"). Type-ins allow for expression evaluation, menus support slot editing, and methods can be entered and edited. If you are familiar with a previous version of the Self system, Section 14.1 of the manual entitled "How to Use Self 3.0" contains a quick introduction to the graphical user interface. The impatient might want to read that first. o A mechanism - the transporter - has been added to allow arbitrary object graphs to be saved into files as Self source. The system has been completely modularized to use the transporter; every item of source now resides in a transporter-generated module. Transport-generated files have the suffix .sm to distinguish them from "handwritten" files (.Self), though this may change as we move away from handwritten source. The transporter is usable but rough, we are still working on it. o Every slot or object may now have an annotation describing the purpose of the slot. In the current system, annotations are strings used to categorize slots. We no longer categorize slots using explicit category parent objects. Extra syntax is provided to annotate objects and slots. o A new profiler has been added, which can properly account for the time spent in different processes and the run-time system, and which presents a source-level profile including type information (i.e., methods inherited by different objects are not amalgamated in the profile, nor are calls to the same method from different sites). It also presents a consistent source-level view, abstracting from the various compiler optimizations (such as inlining) which may confuse the programmer. o Privacy is not enforced, although the privacy syntax is still accepted. The previous scheme was at once too restrictive (in that there was no notion of "friend" objects) and too lax (too many object had access to a private slot). We hope to include a better scheme in the next release. o The "new" compiler has been supplanted by the SIC ("simple inlining compiler"), and the standard configuration of the system is to compile first with a fast non-optimizing compiler and to recompile later with the SIC. Pauses due to compilation or recompilation are much smaller, and applications usually run faster. o Characters are now single-byte strings. There is no separate character traits. o Prioritized inheritance has been removed; the programmer must now manually resolve conflicts. We found the priority mechanism of limited use, and had the potential for obscure errors. 2.4 Bug Reports Bug reports can be sent to self-bugs@self.stanford.edu.

17 Exodus (Storage Man, perst)

What: Exodus project software (Storage Manager & GNU E) From: zwilling@caseus.cs.wisc.edu (Mike Zwilling) Date: 16 Jul 92 04:53:19 GMT In the past there have been discussions in comp.object and comp.databases about persistent storage for object-oriented databases and programming languages. As you may know, the EXODUS Database Toolkit project at the University of Wisconsin has researched these issues and others for a number of years. The purpose of this note is to inform you that the software from the EXODUS project is freely available via anonymous ftp. The EXODUS software includes the EXODUS Storage Manager and the compiler for the E persistent programming language. Also included is documentation, and a suite of test programs for both components. This note briefly describes the software and explains how to obtain it. We currently support DECstation 3100s/5000s and SPARC based workstations. Others have ported the code to HP700s and IBM RS6000s. The EXODUS Storage Manager is a client-server object storage system which provides "storage objects" for storing data, versions of objects, "files" for grouping related storage objects, and indexes for supporting efficient object access. A storage object is an uninterpreted container of bytes which can range in size from a few bytes to hundreds of megabytes. The Storage Manager provides routines to read, overwrite, and efficiently grow and shrink objects. In addition, the Storage Manager provides transactions, lock-based concurrency control, and log-based recovery. GNU E is a persistent, object-oriented programming language developed as part of the Exodus project. GNU E extends C++ with the notion of persistent data, program level data objects that can be transparently used across multiple executions of a program, or multiple programs, without explicit input and output operations. GNU E's form of persistence is based on extensions to the C++ type system to distinguish potentially persistent data objects from objects that are always memory resident. An object is made persistent either by its declaration (via a new "persistent" storage class qualifier) or by its method of allocation (via persistent dynamic allocation using a special overloading of the new operator). The underlying object storage system is the Exodus storage manager, which provides concurrency control and recovery in addition to storage for persistent data. The current release of GNU E is based on gcc/g++ version 2.2.2, and is upward compatible with C++ as implemented by that compiler. A bibliography of EXODUS related papers can be obtained from the ftp site described below. To obtain the software, simply ftp to ftp.cs.wisc.edu (128.105.8.18), login as anonymous with your email address as a password, "cd" to the "exodus" directory, and follow the directions (directions will be given as you "cd"). See the README for the latest information about the software and an indication of our future plans. If you decide to use the software, please contact us at exodus@cs.wisc.edu so that we can notify you of changes.

Ode 2.0 An Object-Oriented Database C++ Compatible, Fast Queries, Complex Application Modeling, Multimedia Support, and more Ode 2.0 is now available to Universities. Users who currently have Ode 1.1 will be automatically sent a tape with Ode 2.0. There is no charge for Ode. However, AT&T requires the signing of a non-disclosure agreement. Details ------- ODE OBJECT-ORIENTED DATABASE The Ode object database is based on the C++ object paradigm. Ode uses one integrated data model (C++ classes) for both database and general purpose manipulation. The Ode database is defined, queried and manipulated in the database programming language O++, which provides simple and elegant facilities for manipulating the database. O++ is an upward-compatible extension of C++. A few facilities have been added to C++ to make it into a database programming language. C++ programmers can learn O++ in a very short time. O++ programs can be compiled with C++ programs thus allowing the use of existing C++ code. THE ODE MODEL OF PERSISTENCE Ode offers a simple and elegant notion of persistence which is modeled on the ``heap''. Specifically, memory is partitioned into volatile and persistent. Volatile objects are allocated in volatile memory (stack or heap). Persistent objects are allocated in persistent store and they continue to exist after the program that created them has terminated. An Ode database is a collection of persistent objects. Each object is identified by a unique object id (i.e., a persistent pointer, or to be precise, a pointer to a persistent object). The database programming language O++ provides facilities for creating and manipulating the Ode database. For example, O++ provides facilities for specifying transactions, creating and manipulating persistent objects, querying the database, creating and manipulating versions. WHAT IS AN OBJECT-ORIENTED DATABASE Some important characteristics of an object-oriented database are: + data is stored as objects, + data can be interpreted (using methods) only as specified by the class designer, + relationship between similar objects is preserved (inheritance), and + references between objects are preserved. ADVANTAGES OF OBJECT-ORIENTED DATABASES + Speed: Queries can be faster because joins (as in relational databases) are often not needed. This is because an object can be retrieved directly without a search, by following object ids. + No impedance mismatch: The same data model is used by both the database programming language and the database; it is not necessary to do any format conversions when reading the data from disk and when storing the data on disk. + Programmers need to learn only one programming language: The same programming language is used for both data definition and data manipulation. + Complex applications: The full power of the database programming language's type system can be used to model the data structures of a complex application and the relationship between the different data items. + Multimedia applications: The semantic information stored in the database (class methods) facilitates correct interpretation of the data. This reduces application complexity since applications do no have to be responsible for the correct interpretation of data. + Versions: Object-oriented databases typically provide better support for versioning. An object can viewed as the set of all its versions. Also, object versions can be treated as full fledged objects. + Triggers and constraints: Object-oriented databases provide systematic support for triggers and constraints which are the basis of active databases. Finally, most, if not all, object-oriented applications that have database needs will benefit from using an object- oriented database. Specifically, C++ applications that have database needs will benefit from using Ode. FEATURES OF ODE 1. Ode is C++ based and compatible with C++. 2. The Ode object database provides four object compatible mechanisms for manipulating and querying the database: O++, OdeView, OdeFS, and CQL++: + O++ is a database programming language based on C++. O++ is upward compatible with C++ and it makes minimal changes to C++. O++ offers a simple and elegant notion of persistence which is modeled on the ``heap''. O++ provides facilities for querying the database, and a variant of other facilities. + OdeView is a graphical X-based interface to the Ode database. + OdeFS is a file system interface to the Ode object database. OdeFS allows objects to be treated and manipulated like files. Standard commands such as rm, cp and mv and tools such as vi and grep can be used to manipulate objects in the database. + CQL++ is a C++ variant of SQL for easing the transition from relational databases to object- oriented databases such as Ode. Currently, only O++ is shipped with Ode 2.0. A beta- test version of OdeFS is available upon request. 3. Ode supports large objects (these are critical for multi-media applications). Ode provides both transparent access for large objects and a file like interface for large objects. The latter can be used to efficiently access and update parts of a large object. 4. Users can create versions of objects. Ode will track the relationship between versions and provides facilities for accessing the different versions. 5. Transactions can be specified as read-only; such transactions are faster because they are not logged and they are less likely to deadlock. 6. Users can run ``hypothetical'' transactions. Hypothetical transaction allow users to pose ``what- if'' scenarios (as often done with spread sheets). User can change data and see the impact of these changes without changing the database. 7. EOS, the storage engine of Ode, is based on a client- server architecture. Some features of EOS: a. Efficient and transparent handling of large objects. A file-like interface is also provided for very large objects. b. Concurrency is based on multi-granularity two- version two-phase locking; it allows many readers and one writer to access the same item simultaneously. c. Log records contain only after images of updates, thus making logs small. Recovery from system failures requires one scan over the log resulting in fast restarts. USE MODES Ode supports two modes of use: 1. Client-server (allows multiple users to access the database concurrently). 2. Single user (improved performance compared to using the client-server mode). USERS Ode 2.0 is currently being used as the multi-media database engine for AT&T's Interactive TV project. Ode 1.1 (older version of Ode with limited capabilities) has also been distributed to 30+ sites within AT&T and 135+ universities.

21 POSTGRES (Ext. Rel. DBMS)

What: Version 4.0 of the POSTGRES DBMS From: mer@gaia.CS.Berkeley.EDU (Jeff Meredith) Date: 16 Jul 92 04:53:17 GMT Version 4.0 of the POSTGRES DBMS is now available for distribution. Version 4.0 provides significant advances in functionality over 3.1. General improvements in the code and some key multi-user bug fixes have resulted in a much more reliable system than we have ever previously released. Major new features include: o Complete support for language (POSTQUEL) functions. o Handling of nested dot expressions. o Optimization of predicates with expensive functions. o Binary portals o Initial support of sets o Indices on system catalogs. Postgres runs on Sparc I, Sparc II, Sun 4 running SunOs, and DECstations running ULTRIX >= 4.0, as well as Sequent Symmetry machines. Postgres consists of about 250,000 lines of C. If you would like to get Postgres 4.0, you can get it in one of two ways: (1) Anonymous FTP from postgres.berkeley.edu cd pub get postgres-setup.me binary get postgres-v4r0.tar.Z quit Or, if you do not have net.access, you can order a Postgres distribution tape by sending a check payable to the Regents of the University of California for $150.00 to: Postgres Project 571 Evans Hall University of California Berkeley, CA 94720. Indicate in your accompanying letter whether you want the system on a 9-track tape at 1600 BPI, at 6250 BPI, on a cartridge tape for SUN shoeboxes (QIC 24 format), or on a TK50 DEC cartridge tape.

24 short tool

From: neil@aldur.demon.co.uk (Neil Wilson) Subject: New version of 'short' available Date: Sat, 7 Aug 1993 09:38:25 +0000 A new beta release (1.2) of 'short' is available from the Stuttgart Eiffel archive (ftp.informatik.uni-stuttgart.de) in directory /pub/eiffel/eiffel-3/sig Command line processing is now included in the short system. Short can now cope with multiple input files, the standard input and deal with most file errors. Short now depends on the argument cluster which is available from the same archive and directory. Short supports the following options: -V, +version, -h, +help Displays the 'short' version information and gives the usage help message for the command. -e, +abstract, +eiffel Produces a fully deferred version of the input class(es) which will compile just like any other class (hopefully :-) -l <class_name>, +view Produces the output from the point of view of the class <class_name> - the "short form for ". Special handling for ANY and NONE of course. By default short outputs the "short form for ANY". -f, +full Produces the short form including all the feature blocks. (Implemented as the "short form for NONE".) -p, +parents Retains the inheritance clause in the output. The default is to drop it. -b <number>, +blank Indent levels by <number> characters. -c <number>, +column Width of the output is <number> characters. Should be greater than 20. Obsolete features are not retained. Obsolete classes retain no features. The output of the tool now conforms to the layout rules in Appendix A of ETL and should look like the 'short' examples in the book. As much as is possible the output and command line options conform to ISE's 2.3 version of 'short'. This release of short has been tested on all the v1.21 Eiffel/S libraries, itself and the argument clusters, plus any other class fragments I had lying around at the time. My biggest debt is of course to David Morgan. This version is only really a tiny modification of his work. His ELEXER Eiffel 3 parser remains the core of the tool. I though am responsible for any remaining deficiencies or problems with this release. Problems, suggestions, comments, criticisms to me please. All gratefully received - I can't improve my Eiffel if somebody doesn't tell me where I blew it.

32 Law of Demeter

From: lieber@ccs.neu.edu (Karl Lieberherr) Subject: Law of Demeter/Adaptive Software Organization: College of CS, Northeastern University Date: Fri, 4 Jun 1993 20:41:49 GMT >... Yes, the Law of Demeter paper is available in electronic form on the net. Indeed, many of the Demeter project papers are available from the ftp server at Northeastern University (see instructions below). The Law of Demeter idea has been automated in the Demeter Tools/C++ as an adaptive software tool which automatically makes much of your C++ code compliant with the Law of Demeter. The tool is an add-on tool to your favorite C++ development environment and is commercially available from Demeter International.

34 Pred Classes (Cecil)

What: "Predicate Classes" paper From: chambers@klamath.cs.washington.edu (Craig Chambers) Date: Fri, 30 Apr 93 01:25:02 GMT "Predicate classes are a new linguistic construct designed to complement normal classes in object-oriented languages. Like a normal class, a predicate class has a set of superclasses, methods, and instance variables. However, unlike a normal class, an object is automatically an instance of a predicate class whenever it satisfies a predicate expression associated with the predicate class. The predicate expression can test the value or state of the object, thus supporting a form of implicit property-based classification that augments the explicit type-based classification provided by normal classes. By associating methods with predicate classes, method lookup can depend not only on the dynamic class of an argument but also on its dynamic value or state. If an object is modified, the property-based classification of an object can change over time, implementing shifts in major behavior modes of the object. A version of predicate classes has been designed and implemented in the context of the Cecil language." Comments on the ideas in the paper are appreciated. -- Craig Chambers

From: M.C.Little@newcastle.ac.uk (Mark Little) Subject: C++SIM Release 1.0 Announcement Organization: Computing Laboratory, U of Newcastle upon Tyne, UK NE17RU Keywords: C++, SIMULA, simulation, object-oriented Date: Mon, 14 Jun 1993 15:02:33 GMT C++SIM 1.0 Release Announcement. This is to announce the release of version 1.0 of C++SIM, a simulation package written in C++. C++SIM provides discrete process based simulation similar to that provided by the simulation class and libraries of SIMULA. The linked list manipulation facilities provided by SIMSET are also included in the package. Inheritance was used throughout the design to an even greater extent than is already provided by SIMULA. This has allowed us to add new functionality without affecting the overall system structure, and hence provides for a more flexible and expandable simulation package. A paper is included which describes the design and implementation of C++SIM and includes a worked example of how to use the package. The paper describes the class hierarchy which we have created, and indicates how it can be used to further refine the simulation package. The simulation package requires the use of a threads package and currently only works with Sun's lightweight process library or the Gnu thread package (which *is* included in the distribution). The package has been used on Sun workstations, and, with the exception of the thread library requirement, contains no system specific code which should make porting to other systems relatively easy. The code has been compiled with Cfront 2.1 and Cfront 3.0.1 and g++ 2.3.3 If you find any bugs or make modifications (e.g., ports to other thread packages) or port it to other systems, then please let me know so I can keep the sources up-to-date for other users. The package is available via anonymous ftp from arjuna.ncl.ac.uk

40 C++ Signatures (subtyping)

From: gb@cs.purdue.edu (Gerald Baumgartner) Newsgroups: comp.object,comp.lang.c++ Subject: signature implementation for G++ 2.5.2 and tech report available Date: 4 Nov 1993 12:03:00 -0500 Organization: Department of Computer Sciences, Purdue University Announcing the paper Signatures: A C++ Extension for Type Abstraction and Subtype Polymorphism by Gerald Baumgartner and Vincent F. Russo. Tech report CSD-TR-93-059, Dept. of Computer Sciences, Purdue University, September 1993. Submitted to Software Practice & Experience. and a beta release of our implementation of signatures for GCC 2.5.2. How to Get that Stuff? ---------------------- You can get both the paper and the implementation by ftp from host: ftp.cs.purdue.edu (128.10.2.1) login: anonymous password: your e-mail address directory: pub/gb files: COPYING Copyright notice. README This file. Signatures.{dvi,ps}.gz DVI and Postscript versions of the paper. gcc-2.5.2.sig.diff.gz Patch to upgrade GCC 2.5.2. test.tar.gz Test files and script to run the tests. To make GCC 2.5.2 understand signatures, just copy the context diff file into the GCC source directory, type gunzip gcc-2.5.2.sig.diff.gz patch < gcc-2.5.2.sig.diff and rebuild and install `gcc,' `cc1plus,' the man pages, and the manual. For compiling C++ code containing signatures, you need to use the command line option -fhandle-signatures We tested our extension on Sun 4 only, but since there are no changes to the compiler backend, it is expected work on other architectures as well. To test whether it works on your architecture, unpack the file `test.tar.gz' and run the shell script Test It compiles the test programs and runs them. If everything works correctly, all the test programs (all 40 of them) should print Hello World. What are Signatures anyway? --------------------------- Roughly, signatures are type abstractions or interfaces of classes. They are related to ML's signatures, categories in Axiom, definition modules in Modula-2, interface modules in Modula-3, and types in POOL-I. The main language constructs added are signatures and signature pointers. For example, the signature declaration signature S { int foo (void); int bar (int); }; defines a new abstract type `S' with member functions `int foo (void)' and `int bar (int).' Signature types cannot be instantiated since they don't provide any implementation. Only signature pointers and signature references can be defined. For example, C obj; S * p = &obj; defines a signature pointer `p' and initializes it to point to an object of class type `C,' where `C' is required to contain the public member functions `int foo (void)' and `int bar (int).' The member function call int i = p->foo (); executes then `obj.foo ().' Class `C' is called an implementation of the abstract type `S.' In this example, we could have made `S' an abstract virtual class and `C' a subclass of `S,' and we would have had the same effect. The advantages of signatures over abstract virtual classes are - you can build a type hierarchy separate from the class inheritance (implementation) hierarchy, - subtyping becomes decoupled from inheritance, and - signatures can be used with compiled classes, while you cannot retrofit an abstract virtual class on top of compiled class hierarchies. For more information, please, see the paper. What's Implemented and what's not? ---------------------------------- Signature declarations and signature pointers are implemented and working. For examples of what's working and how to use them you can have a look at the test files. The following bugs are known: - The destructor of objects cannot be called though signature pointers. - A signature pointer cannot point to an object of a class defined by multiple inheritance. - The signature conformance check does not work if the signature contains other signature declarations or class declarations. - Operator and conversion operator member functions of signatures can only be called with function call syntax, such as `p->operator+(17),' but not with operator or conversion syntax. The following language constructs and features are not yet implemented: - constants in signatures, - signature references, - signature inheritance, - the `sigof' (signature of a class) construct, - views (not even the parsing is done), - signature templates, and - exception specifications in signature member function declarations. The following optimization is not implemented: - Looking up a virtual class member function through a signature pointer/reference requires double indirection. This can be optimized by memoizing, so that only the first lookup of a member function requires double indirection and further lookups require only single indirection. The items above are roughly in the order in which they will be implemented. Besides bug fixes, the main features that have been implemented since the last release are default implementations of signature member functions and opaque types.

41 The Texas Persistent Store

The Texas Persistent Store, version 0.1 Texas is a simple, portable, high-performance and (best of all) FREE persistent store for C++ using "pointer swizzling at page fault time" to translate persistent addresses to hardware-supported virtual addresses. Texas is built on top of a normal virtual memory, and relies on the underlying virtual memory system for caching. It uses user-level virtual memory protections to control the faulting of data from a persistent storage file into virtual memory. All addresses in a page are translated from a persistent format to actual virtual addresses when the page is brought into virtual memory, and subsequent memory references (including pointer traversals) are just as fast as for non-persistent data. Texas is easy to use, and is implemented as a UNIX library. It is small and can be linked into applications. It requires no special operating system privileges, and persistence is orthogonal to type---objects may be allocated on either a conventional transient heap, or on the persistent heap, as desired. Texas supports simple checkpointing of heap data. A log-structured storage module is under development, and will provide fast checkpointing of small transactions. Texas is beta software, and the current prerelease version supports only simple single-machine operation. Future releases will support client-server operation, a flexible access control scheme, and transaction support. Texas currently runs under SunOS and ULTRIX, using Sun CC or GNU C++. Porting to other modern systems (e.g., OS/2, WNT, Mach) should be easy---it requires only mprotect(), signal(), and sbrk() calls (or their equivalent) to control virtual memory protection setting and trap handling. Papers about the pointer swizzling scheme and Texas itself (referenced below) are available via anonymous ftp from cs.utexas.edu (IP address 128.83.139.9), as postscript files swizz.ps and texaspstore.ps in the directory pub/garbage.

42 OSE C++lib

From: Graham.Dumpleton@nms.otc.com.au (Graham Dumpleton) Date: Tue, 9 May 1995 08:58:55 +1000 (EST) OSE is a collection of programming tools and class libraries for C++. The core of the environment is the C++ class libraries, of which three are provided. These are: OTCLIB - A library of generic components, including support for error handling, error message logging, error recovery, program debugging, memory management, resource management, generic collections, text manipulation, date/time, operating system interfacing and event driven systems. OUXLIB - A library of components which primarily extends classes in the OTCLIB library to support features specific to the UNIX operating system. OTKLIB - A library of components which builds on the OTCLIB and OUXLIB libraries to allow integration of the TCL/TK library into applications using the event driven systems framework provided by the OTCLIB library. The C++ libraries are portable to a wide range of C++ compilers on the UNIX platform. Supported C++ compilers include those from ATT/USL (CFRONT), CenterLine, DEC, HP, IBM, Lucid, ObjectStore, SGI (CFRONT), SGI (DELTA), Sun (CFRONT) and Sun (NATIVE), as well as the freely available GNU C++ compiler. If your C++ compiler does not support templates, it is possible to use a template preprocessor which is supplied with OSE. If your C++ compiler support exceptions, they will be used. Portability to all the major variants of UNIX has been achieved. Supported platforms include AIX, BSD, HPUX, IRIX, Linux, NeXT, OSF, SCO, Solaris, SunOS, SYSV and Ultrix. In addition to being available under UNIX, the OTCLIB library has been ported to DOS, OS/2 and Windows NT using Borland, Watcom and Microsoft C++ compilers. The C++ libraries have been fully integrated with the ObjectStore OODBMS, allowing instances of classes from the C++ libraries to be made persistent. The C++ libraries can also be used in conjunction with applications using Versant, although in this case instances of classes from the C++ libraries cannot be made persistent. In addition to the C++ libraries, a build environment is provided. The build environment greatly simplifies the writing of makefiles, making the the task of building applications, as well as the generation and installation of both static and shared libraries easy. The details of template instantiation for many of the C++ compilers is also hidden, making it possible to write makefiles which are portable between different C++ compilers as well as different platforms. The build environment also supports tasks such as schema generation for the ObjectStore and Versant OODBMS, and testing of applications using tools such as Purify, Quantify, PureCoverage, TestCenter and Sentinel. Comprehensive documentation for the C++ libraries and build environment is provided. Documentation for the C++ libraries comes in the form of a UNIX style manual page for each class and higher level documentation giving examples of how to use the classes. The UNIX style manual pages are generated from the class header files using documentation extraction tools. These tools are provided with OSE and are capable of generating both UNIX style manual pages and Frame documents. Development of OSE commenced in 1990, being made freely available via the Internet in 1993. OSE was winner of CODA'94, the ComputerWorld Object Developer Awards, held in conjunction with ObjectWorld in Sydney, Australia. The category in which OSE was a winner was "Best implementation of a reusable development environment for company deployment".

As I see it, predicate classes are a key step towards solving one of the most frustrating problems of OO programming: the struggle over whether to encode some difference among objects in the value of a slot (that is one of its parts) or in the object's `method table' (class or that which it is one-of). A closely related problem, that has also come up in this series of messages, is how so-called factory objects can dynamically select the behavior of the objects they create. We have developed a new OO language concept called Traces, that can be used to make much more powerful factory objects, as well as handle some of the things predicate classes do. The two ideas are similar in that they both make behavior selection a much more dynamic phenomena. My ISOTAS'93 paper presents the concept of Traces and shows it application to some problems. This paper is available for anonymous FTP from ftp.parc.xerox.com, in the /pub/mops directory. The file is traces.ps. Gregor Following is the abstract from the paper: Object-oriented techniques are a powerful tool for making a system end-programmer specializable. But, in cases where the system not only accepts objects as input, but also creates objects internally, specialization has been more difficult. This has been referred to as the ``make isn't generic problem.'' We present a new \oo{} language concept, called traces, that we have used successfully to support specialization in cases that were previously cumbersome. The concept of traces makes a fundamental separation between two kinds of inheritance in \oo{} languages: inheritance of default implementation -- an aspect of code sharing; and inheritance of specialization, a sometimes static, sometimes dynamic phenomenon.

From: ad@munta.cs.mu.OZ.AU (Andrew Davison) Subject: BeBOP v.1.0 Available Message-ID: <9325614.15552@mulga.cs.mu.OZ.AU> Organization: Department of Computer Sci, University of Melbourne Follow-Up: comp.parallel Date: Mon, 13 Sep 1993 04:08:41 GMT BeBOP and bp Version 1.0 now available ====================================== What is BeBOP? ============== The language BeBOP is a unique combination of sequential and parallel Logic Programming (LP), object oriented programming and meta-level programming. The LP component offers both don't know non-determinism and stream AND-parallelism, a combination not possible with concurrent LP languages. BeBOP's object oriented features include object IDs, encapsulation, message passing, state updating, and object behaviour modification. The meta-level capabilities are based on the treatment of Prolog theories as first order entities, which enables them to be updated easily, and for fragments to be passed between objects in messages. BeBOP is implemented by translation down to NU-Prolog, and its parallel extension, PNU-Prolog. An unusual aspect of this is the way that object IDs are utilized as a communication mechanism between objects. What is bp? =========== The bp interactive interpreter supports BeBOP programming by allowing the flexible invocation of objects, and offering the means for setting up communication links between objects at any time. An incidental benefit is the ability to use `global' variables in queries. Since bp is an augmentation of the NU-Prolog np system, objects and Prolog goals can be combined, and a by-product is that the floundering of Prolog queries is avoided. Where are they? =============== The BeBOP system (BeBOP and bp), and the PNU-Prolog preprocessor pnp, can be found at the anonymous ftp site munnari.oz.au (128.250.1.21), in the directory pub as the file bebop.tar.Z. Remember to use binary mode when copying it. The release comes with a user manual, several papers (in Postscript format), sample programs, and source code. System requirements =================== The BeBOP system requires the following: * The NU-Prolog system, compiler and interpreter * The pnp preprocessor (this is included as part of the BeBOP system release) * GCC or similar compiler * Yacc (or Bison) and Lex For more details, contact: ========================== Andrew Davison Dept. of Computer Science University of Melbourne Parkville, Victoria 3052 Australia Email: ad@cs.mu.oz.au Fax: +61 3 348 1184 Phone: +61 3 287 9172 / 9101 Telex: AA 35185

Khosla, "Design of Dynamically Reconfigurable Real-Time Software using Port-Based Objects," Carnegie Mellon University Tech Report #CMU-RI-TR-93-11, July 1993. Abstract: The current development of applications for sensor-based robotic and automation (R&A) systems is typically a `one-of-a-kind' process, where most software is developed from scratch, even though much of the code is similar to code written for other applications. The cost of these systems can be drastically reduced and the capability of these systems improved by providing a suitable software framework for all R&A sys tems. We describe a novel software framework, based on the notion of dynamically reconfigurable software for sensor-based control systems. Tools to support the implementation of this framework have been built into the Chimera 3.0 Real-Time Operating System. The framework provides for the systematic development and predictable execution of flexible R&A applications while maintaining the ability to reuse code from previous applications. It combines object-oriented design of software with port-automaton design of digital control systems. A control module is an instance of a class of port-based objects. A task set is formed by integrating objects from a module library to form a specific configuration. An implementation using global state variables for the automatic integration of port-based objects is presented. A control subsystem is a collection of jobs which are executed one at a time, and can be programmed by a user. Multiple control subsystems can execute in parallel, and operate either independently or cooperatively. One of the fundamental concepts of reconfigurable software design is that modules are developed independent of the target hardware. Our framework defines classes of reconfigurable device driver objects for proving hardware independence to I/O devices, sensors, actuators, and special purpose processors. Hardware independent real-time communication mechanisms for inter-subsystem communication are also described. Along with providing a foundation for design of dynamically reconfigurable real-time software, we are also developing many modules for the control module, device driver, and subroutine libraries. As the libraries continue to grow, they will form the basis of code that can eventually be used by future R&A applications. There will no longer be a need for developing software from scratch for new applications, since many required modules will already be available in one of the libraries.

On WUArchive (wuarchive.wustl.edu) there is a series of slides developed in Microsoft's PowerPoint. The course material includes lesson plans, tests, and workbooks, along with full notes accompanying each slide. There's one _little_ catch -- it's in the Public Ada Library. Now, the OOP course (there's three courses, one on OOD, OOP, and Software Engineering) covers both C++ and Ada. It was designed to let the students work in both languages to get an objective opinion of the pluses and minuses of each language (gee, what a concept!). The OOD slides do NOT cover OMT. Some material is used from Booch's OOD book, but not the notation. From looking at the slides, it appears very easy to insert your own notation. The important part for students is communicating the concepts, which (for the price) these slides do a DAMN good job of. <- (Safire's Violation #45: "A perposition is a bad thing to end a sentence with." :-) Ah, but WHERE on WUArchive are they?

REPORTS AVAILABLE FROM THE DISTRIBUTED OBJECT COMPUTING DEPARTMENT GTE LABORATORIES INCORPORATED 40 Sylvan Road, M/S 62 Waltham, Massachusetts 02254 For over six years, the primary focus of the Distributed Object Computing Department within GTE Laboratories has been the Distributed Object Management (DOM) project. The DOM project conducts research into object-oriented technology for integrating heterogeneous, autonomous, distributed (HAD) computer systems/resources. Major research areas include: interoperable object models; interoperable, distributed object architectures; heterogeneous, extended transaction models; and information requests in HAD environments. We are experimenting in these areas using our prototype DOM system which we have developed over the past five years. This technology is based on ideas from a number of technical areas including distributed, object-oriented, databases, multi-database systems, operating systems, and programming languages.

53 KEOBJ, OO DSP micro-kernel

From: clb@softia.com (Chris Bidaut) Subject: Object kernel for DSP & RISC processors Date: Mon, 15 Nov 1993 22:48:46 Organization: Softia, Inc. This is an announcement for KEOBJ, an object-oriented micro-kernel for Digital Signal Processors (DSP) and RISC processors. This is also a request for comments from the Internet community. Feedback on the architecture and programming interface will be appreciated and incorporated into the next release. 1 DESCRIPTION ------------- KEOBJ is an object-oriented micro-kernel optimized for advanced embedded applications, and it particularly targets Digital Signal Processors (DSP) and RISC processors in multimedia environments. Its main features are object-orientation, real-time behavior, signal processing support, micro-kernel architecture and scalability. 1.1 Object-orientation The kernel is a collection of system classes exported to the applications (e.g Process, Thread, Memory, ...). An object name space provides a way to locate any public object (e.g. IPC, memory) using a symbolic path. The kernel is written in C++ and is easily portable. 1.2 Real-time behavior The design stresses fast response time and predictability to qualify for the real-time label. The kernel is reentrant and preeemptable. 1.3 Signal processing support Besides providing an architecture appropriate for most general purpose applications, the kernel incorporates dedicated features for signal processing applications. This includes two phases interrupt processing, time-deadline scheduling, Inter Process Communications, multiple memory pools, awareness of the constraints due to a single data type (word). 1.4 Micro-kernel architecture Probably the most important feature of the kernel is the ability to be extended at run-time with new services such as devices drivers, public classes (IPC, file systems, windowing systems). Applications and system services are dynamically loaded by a COFF compatible loader. The core kernel is customizable at run-time through a personality mechanism to emulate other environments (Operating systems) or to tailor the processes environments. 1.5 Scalability The API supports physical and virtual memory organizations with the same semantics. Applications source code will be portable across DSP and RISC processors. The architecture supports symmetric multiprocessing and distribution (Available by mid-1994). 2 WHERE TO FIND THE PACKAGE --------------------------- A set of documentation about KEOBJ is available via anonymous ftp on the following Internet server: netcom.com (192.100.81.100) in file /pub/softia/keobj.zip If you do not have access to Internet, contact me for other delivery media at: Chris Bidaut clb@softia.com Telephone (408) 262-6520 Fax (408) 262-7210
