Previous releases of LEAP have been of the Borland Pascal, MS-DOS system. This is the first release of the Unix version. Full C source code is included, and is distributed under the terms of the GNU General Public License - details of which are included in the distribution. LEAP is a relational database management System that can easily be used as an educational tool. It supports the relational algebra as a query language, and many examples from popular Database texts are included in the standard distribution. It is distributed free of charge, under the GNU General Public License. The author only requests feedback on the system in return. For more information on LEAP, and instructions on how to download the current release(s), please have a look at the NEW Leap home page (Now completely revised, as of 3rd September, 1996): http://www.brookes.ac.uk/~e0190404/leap.html There is also a mailing list concerning LEAP, to subscribe, send a one line e-mail to: majordomo@brookes.ac.uk - The one line (in the body) containing "subscribe leap". A line containing "help" will include more information on options. The remainder of this e-mail concerns the C release. The Pascal/MS-DOS release may also be downloaded via the above URL. This release constitutes Alpha release 0.7.0 of version 0.11 of LEAP. The code is still VERY much in development, and has quite a long way to go before it is truly portable to multiple architectures. As of 3rd September, LEAP compiles and runs with no problems on: x Linux 1.2.13 x Solaris 2.4 It has been compiled, to various extents, on SunOS, NeXt, Windows/DOS, and Ultrix systems. Subsequent (alpha) versions will support these systems. The GNU C compiler/Debugger has been used for development, but ANSI compliant C compilers should work. BSD/POSIX issues affect the portability to all Unix platforms. The system is an alpha release, and has a number of large functionality gaps. However, at this stage: x All relational operators are supported x Source files are supported x The query/condition parser works and is extendable x Previous examples should work Later releases are not following any rough schedule. Major announcements will be sent to various (appropriate) newsgroups, and (of course), the LEAP mailing list. 0.8.0 - Support for existing 0.10 functionality. Efficent memory usage. 0.9.0 - Minor issues resolved, rewrites of bad routines/modules. 0.10.0- Portability and functionality bugs resolved. Subsequent releases will constitute Beta 0.11, and release 1.0 will occur when stability has been attained on multiple platforms. If you have any further questions or comments, please direct them either to the leap mailing list, or to myself at the following e-mail address.

Compiled using the Standard Sun C compiler. Ultrix 4.4 - Compiles LEAP, but unfortunately cores straight away. This smacks of a silly pointer issue that other OS ignore. Compiled using gcc. NeXt - Compiles LEAP, but has a bit of a problem with creating files. Compiled using gcc. In all of the above, in order to get it to compile/run, remove the: if (errno!=ENOENT) in relation.c - This appears to be a Linux specific, and should be removed. I'll include this "fix" in the next release.

These have (hopefully) been rectified. The Unix Download page now includes: x TEMPORARY link to sunsite.unc.edu incoming directory where I have uploaded leap for positioning. (/pub/Linux/Incoming). x Link to the expected final location of LEAP on sunsite (/pub/Linux/apps/databases) x Page containing the UUENCODED version of the 0.7.1 distribution. Just click on this, save to file, and run uuedecode against resulting file. If you continue to have problems, please let me know. Oh, and the version up there now is 0.7.1, which has a few minor improvements, and the start of the regression test scripts. The distribution now is LSM "compliant", ie. all in one file, with src directory, and LSM entry.

The remaining 5% are minor items relating to obscure functionality that I'm yet to turn my attention to. - LEAP contains an automatic configuration script, generated by GNU autoconf, which should enable it to be compiled on any Unix architecture. There are still various issues to be resolved, but LEAP should work. Let me know how you get on. Full details are included in the distribution. - Regression test scripts which should check basic functionality are included. Check out src/tests I'll be uploading the current distribution - leap-0.8.3.tar.gz to sunsite.unc.edu /pub/Linux/Incoming later today, and also to ftp.demon.co.uk /pub/compsci/databases/leap (which will take a few days to be positioned), as will micros.hensa.ac.uk. If you'd like me to ftp it somewhere else for you. please let me know. Check out the home page for more information: http://www.brookes.ac.uk/~e0190404/leap.html What's next? - Remaining compatibility/portability items. - Complete implementation of the existing (DOS) support environment. - Documentation transfer to Unix. At this point, LEAP will reach Beta 0.11 (ie. the next "major" version of LEAP). I'd like to then spend a bit of time on getting the 'C' version running under DOS/Windows. At this point, I think I will finally make LEAP a "real " program, ie. Version 1.0 After that? New functionality. All sorts of things are possible then...

This means that it will be mirrored around the world by all the sunsite machines that also mirror the Linux subdirectoy! The "master" server is sunsite.unc.edu, but the mirrors are numerous. It is located in /pub/Linux/apps/databases - and the current version is 0.8.3 (The most recent version) - leap-0.8.tar.gz is the filename. There is a link on the LEAP homepage. The only problem I can forsee is how often the Linux archives are updated. It might take some time for a new version to be placed correctly. As always, let me know if you have any problems, questions etc. regarding downloading, or anything else related to LEAP.
