Much appreciated. I'm curious how you got hold of the Pascal version... I've been trying to get rid of it for quite a while - it's *so* old and unstable (in comparison). Any pointers would be much appreciated. >Richard, having down loaded the LEAP program I am most interested to begin >to examine it in much detail.

LEAP doesn't have SQL query support (yet - it's probably a version 2 thing, if I ever get that far)... >However my current work environment is Delphi 3 not Turbo Pascal 7.

LEAP has an EasyWin version - which sucks - it is simply a port of the latest version to Windows using Borlands EasyWin target - which gives you basic support, but no more. You can't cut/paste, scroll etc. LEAP also has a native Win32 version, compiled from the 'C' version, using Cygnus Solutions GNUWin project, which allows Unix programs written with the GNU utilities to be ported with no code modifications. It is a console binary. Again, no scroll bars, but cut/pasting is easier. It's also much faster and reliable. >P.S Since writing this I have gone to your home page and found the version >I've downloaded istruely out of date. >Question : Your new work is all in 'C'? Is there any activity in Pascal?. Yes. (All 'C'). No (Pascal is dead. Long live C). >I'm pretty good at general programing in Delphi, but know very little of >the 'real' work of a RDBMS. I may be able to help put of pretty face on an >old workhorse. ( But I would like it in PASCAL) Here's where I'll start getting excited. LEAP will only be a 'C' program from now. The three reasons are: Portability; Portability and Portability. B orland Pascal (and, for that matter, Delphi) is *NOT* portable beyond Windows. ANSI-C is portable to practically any architecture. Linux, Solaris, AIX, SunOS, Windows, Windows-NT, Next, Ultrix all run LEAP without problems. Beat that in Delphi. However, I'm well aware of the fact that LEAP does not have a pretty face. CLI's are rather frustrating, and some form of graphical interface would be wonderful. Unfortunately, making it portable has rather stumped me. My thoughts recently have circled around putting a CGI wrapper around LEAP and give it a Web based interface, which would solve the portability issue. There was some work going on with LEAP in Sweden with something java-ish, but I've unfortunately not heard anything in a long time so cannot say any more. Nonetheless, a LEAP GUI of some description, whatever it's written in, would be beneficial to making LEAP more useful as a teaching tool. On this matter, I'm sure there are mechanisms to allow library functions (generated from 'C'), to be called from Delphi. There were in Borland Pascal... I suppose if a DLL is generated, we've not got a problem, but processing structures might not be as easy... The structure of LEAP 1.1.x has LEAP broken into a library (with all the functions), and the cli, which simply calls process_query(db,query). A relation is returned. Any GUI should therefore only need to build a query, determine which database it is to be run in, pass the parameters, and then process the result. Functions exist to return tuples in a structure that can easily be processed and displayed with all their spangly scroll bars and buttons. I'd be interested in your ideas and thoughts. One last note, you originally sent this e-mail to the LEAP mailing list. I've replied to the mailing list just in case anybody was interested in my reply. If you'd like to take this offline, then please reply to rleyton@acm.org Regards, Richard. >From leap-owner Thu Dec 11 00:38:22 1997 Received: by brookes.ac.uk (8.8.7/SMI-SVR4) id AAA29513; Thu, 11 Dec 1997 00:38:21 GMT From: Richard Leyton To: LEAP Mailing List Subject: leap list: LEAP 1.1 - Next release Date: Thu, 11 Dec 1997 00:31:32 -0000 Message-ID: <01bd05cc$217317a0$c2c0dec2@dogbert.demon.co.uk> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.71.1712.3 X-MimeOLE: Produced By Microsoft MimeOLE V4.71.1712.3 Sender: leap@brookes.ac.uk Precedence: bulk Reply-To: leap@brookes.ac.uk Ladies and Gents, I'm pleased to be able to say I shall be releasing what I hope to be the penultimate LEAP 1.1 beta release (1.1.7) at the weekend. This version contains a fair amount of new functionality, namely: * create database operator implemented (create database (db)) * reverse operator implemented - To reverse engineer a database. * create relation operator changed to allow nesting: relation (name) ((a1,t1,l1),...) * Complete auto-install of LEAP, no conversion process required. * Multitude of Bug-fixes These changes really make the installation of LEAP much simpler. Once LEAP is installed and compiled, a 'make install' will BUILD the default database suite FROM SCRATCH using a generic script which creates and populates the databases, relations, scripts as necessary. This will, in time, enable the footprint of LEAP to be minimal in a home directory, and the main binaries to reside in a central location. The 1.1.4 and earlier 1.1 distributions would require the old format relations to exist, and require a 'convert' program to be run on each database. The tar/zip file does not therefore contain a 'database' heirarchy any more. Once I've stabalised 1.1.7 (as it stands, it's main bug is memory leaks. It's as stable as it's ever been before.), 1.1.8 will follow as a 'final-beta'. Once that's survived without any major changes or bugs, I'll rebadge it 1.2 and push it out as a 'stable' release for use by all and sundry. I'll fix problems to it in the 1.2, but new functionality will start appearing in 1.3 (as 1.1 does to 1.0). Hope that makes sense. Here's the complete list of 1.1/1.2 functionality: * Self contained relations, no seperate files (.tmp, .fld, .rel) * Seperate Utilities included for conversion/analysing databases. * Command line editing using GNU readline, gives Emacs, vi like editor * delete routine implemented. * Activity log implemented to record user activity. * Database to open specified on command line (-b dbname). * Optimisation step * Incorrectly specified "create relation" commands clean up if incorrect data type specified. * create database operator * reverse operator implemented - To reverse engineer a database. * create relation can be nested. * LEAP auto-installs As always, the LEAP web page is at: http://www.dogbert.demon.co.uk/leap.html This information will be updated on the Web page in the next few days. My apologies for not being very active on the LEAP development of late, as always, work got heavy, and it is the party season, and you just *can't* turn down free beer when it's offered. It's just not cricket... 8-) Regards, Richard. -- Richard Leyton mailto:rleyton@acm.org >From leap-owner Sun Dec 14 22:22:42 1997 Received: by brookes.ac.uk (8.8.7/SMI-SVR4) id WAA24476; Sun, 14 Dec 1997 22:21:59 GMT From: Richard Leyton To: LEAP Mailing List Subject: leap list: LEAP 1.1.7 released Date: Sun, 14 Dec 1997 21:22:14 -0000 Message-ID: <01bd08d6$596114c0$c2c0dec2@dogbert.demon.co.uk> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.71.1712.3 X-MimeOLE: Produced By Microsoft MimeOLE V4.71.1712.3 Sender: leap@brookes.ac.uk Precedence: bulk Reply-To: leap@brookes.ac.uk Dear all, I've just completed releasing LEAP 1.1.7 to: ftp://ftp.demon.co.uk/pub/compsci/databases/leap/leap-1.1.7.tar.gz ftp://sunsite.unc.edu/pub/Linux/Incoming/leap-1.1.7.tar.gz Links are of course available at: http://www.dogbert.demon.co.uk/leap.html LEAP 1.1.7 is definately worth getting your mits on. It's considerably better than any other 1.1 release previously, and it's considerably smaller. The compressed archive is 163k, versus 230k (1.1.3). It's about 400k smaller uncompressed. The space has been recovered by removing old documentation, the databases archive, and the regression test suite (which will be included in 1.2 - it's not working yet with 1.1). It is also much more stable, as I've identified a few risky sections of code that would cause a core dump or GPF. The only thing I am not happy with is the documentation. It's still very much 1.0 documentation. I'll be updating it for the first 1.2 release. I've also managed to clear up almost all of the memory leaks. Something I thought would have to wait until 1.1.8. To install LEAP, you must first "make install" - as this builds the "database" heirarchy (-c on it's own merely builds the 'user' and 'master' databases). The install.src builds the date, korth and stanczyk databases with all their examples. Take a look at this for lots of good examples on the new 1.1.7 features. With the holiday season almost upon us, I very much expect this will be the last announcement on LEAP for a fair few weeks. I'll drop any bug fixes to the list as soon as they're discovered though. Wishing you all a happy new year!

To my knowledge difference and join are the worst hit. 1.1.7 also has a couple of technical bugs that manifest themselves when the size of data in a particular attribute is the maximum size of the attribute (ex_auth in the stanczyk database is a good example). All to do with NULL terminators in 'C'... *sigh* - It brings back memories of data structure lecturers - it's ALWAYS the boundary conditions that catch you out. Anyway - my advice, as always, - stick with 1.0 as a stable release for any serious use. 1.1.x is BETA, and bugs are still buzzing around. I'm hoping to get 1.1.8 (which should fix the above bugs) out by the end of this week, but chances are it may not be after Christmas, Oxford Street being what it is... ;-) Do keep those bug reports coming... Hopefully, you're all going to be on holiday/vacation anyway, and will read this after 1.1.8 is available!!! Have a good one! Richard. -- Richard Leyton mailto:rleyton@acm.org
