[Monetdb-developers] Re: [MonetDB-users] AMD64 version of MonetDB for Windows?
by Peter Boncz 15 Nov '05

15 Nov '05

Hi Fabian, I just got my new workstation and it is an AMD64 machine with windows64 installed. I also got myself both the microsoft 64 bits compiler as well as the intel 64 bits compiler. With the particular goal of course to port MonetDB. I am not promising any timeframe but if we don't have a native windows64 port in the next couple of months I would be very surprised if not disappointed. Peter >> >> >> >> Just a small note.

Re: [Monetdb-developers] DBD::monetdb: DBI registration

O.k., FYI, I registered the 'monetdb_' prefix within DBI: <http://www.xray.mpe.mpg.de/mailing-lists/dbi/2005-08/msg00102.html> As soon as Tim commits this patch, you'll see it here: <http://svn.perl.org/viewcvs/modules/dbi/trunk/DBI.pm?view=log> Further on, I proposed DBD::monetdb for inclusion in the Module List <http://www.xray.mpe.mpg.de/mailing-lists/modules/2005-08/msg00695.html> Usually, this takes time. (Somebody of the module list maintainers has to acknowledge the proposal.) Certainly, DBI users expect to find a DBI driver on CPAN: <http://search.cpan.org/modlist/Database_Interfaces/DBD> Do you have any objections that I upload snapshots of DBD::monetdb to CPAN? Such a package will be generated as follows: cd MonetDB/src/mapi/clients/perl/DBD Makefile.PL make dist I'm aware that currently, with its MapiLib dependency, the package isn't very useful on its own - the user needs a MonetDB client anyway. That's not nice, but nothing out of the ordinary (and it may be changed). Steffen

[Monetdb-developers] JDBC: transaction/savepoint issue
by Andrei Martsinchyk 02 Sep '05

02 Sep '05

Hello, I am trying to use MonetDB as a backend for Java application I am developing. I have noticed that inserts the application does have no effect. Statements are executed without exceptions, but data rows do not get into table. I have investigated the problem and have figured out that problem is in transaction and savepoint handling. If transaction had savepoints, it could be silently rolled back when Connection.commit() is called. I have finished with short Java program that demonstrate the bug(?), I am attaching it to the message. Please, take a look. I tested with MonetDB-4.8.2+sql-2.8.2 (release, source tarball) and with MonetDB-4.8.3+sql-2.8.3 (nightly build, August 30). Platforms: 32-bit Linux RedHat 9, 32-bit Linux Ubuntu 5.04 -- Best regards, Andrei Martsinchyk mailto:andrei.martsinchyk@gmail.com

[Monetdb-developers] Directories not created by install
by Robi Sen 02 Sep '05

02 Sep '05

I just installed the windows version of MonetDB and tried to follow the Tutorial on Mknife but was unable to connect. Looking at my system neither of the files /infosets/MILinfoset.xml;/infosets/MILdemo.xml where created nor where the directories. Is this a know issue?

I just found the immense TestWeb page today. I was initially assuming that pathfinder was distributed with its tests like MonetDB. [Side node: IMO, the web page might be easier to navigate if the subnodes on the left hand side had the same content as the submenus on the top bar. E.g. Starting from http://monetdb.cwi.nl/XQuery/index.html and clicking the Development on the left hand side lists a submenu 'Download from CVS', while clicking Development on the top takes me to a page with 'Partners', 'Contributors', 'TestWeb', etc on the left menu. This was how I missed the TestWeb earlier] Your were right about Mtest not being in my path. I forgot to 'rehash' after installing MonetDB. Cheers - EA

Just type `make check'. Be aware, though, that those test cases take their time. Also note that there are currently some tests in that do not work as expected. So you will not get a 100% pass. The `make check' run will print a summary after processing. You will also find a directory that contains the detailed test results marked up with HTML (directory `mTests'). Tests with unexpected outcome are highlighted in red; you will see the diffs between actual and expected outcome. Results of the nightly test runs, btw., are available on the MonetDB TestWeb website: http://monetdb.cwi.nl/Development/TestWeb/index.html. > Re: The usecases.

Most test cases are tested ``by hand'', sometimes by comparing against other implementations. At least in theory, all of them are cross-checked by hand. > > (well, you may redefine a function with same name, but > > different number of arguments). > Wow, I didn't know that.

[Monetdb-developers] new requirements for building MonetDB and associated projects
by Sjoerd Mullender 24 Aug '05

24 Aug '05

There is a new (well already quite a few weeks old) CVS module available at our SourceForge repository called buildtools. This module is now a prerequisite for compiling MonetDB and all other projects. Check out buildtools: export CVSROOT=... cvs checkout buildtools cd buildtools # read REAME file and follow instructions Then you can update your MonetDB and other projects and bootstrap and build those projects. The main difference is: - autogen.py must be found in your $PATH (autogen is now part of buildtools); - Mx must either be found in your $PATH, or you must specify the option --with-mx=.../Mx on the configure command line; - mel must either be found in your $PATH, or you must specify the option --with-mel=.../mel on the configure command line; - for Pathfinder, burg must either be found in your $PATH, or you must specify --with-burg=.../burg on the configure command line. -- Sjoerd Mullender

[Monetdb-developers] AMD64 version of MonetDB for Windows?
by Cardillo Raymond A Civ AFRL/IFEA 19 Aug '05

19 Aug '05

Has anyone out there taken the time to build an MSI for the AMD64 versions of Windows? The x64 version of Windows was released a few months ago and was available in Beta for a while, so I'm hoping someone has either done this already, or can provide some advice on how to build/compile for this platform. Anyone know of future plans to make this one of the standard platform builds? Windows x64 is only going to grow in popularity from here, especially amongst researchers and others who can benefit from 64 bits. Thanks for any info, Ray Cardillo

[Monetdb-developers] quotes around chr values
by Sjoerd Mullender 17 Aug '05

17 Aug '05

I have prepared a patch to put (single) quotes around chr values in tables as printed by the Mserver. E.g.: MonetDB>'a'.print(); [ 'a' ] Previously this resulted in MonetDB>'a'.print(); [ a ] In addition to adding quotes, my patch also escapes control characters: MonetDB>chr(10).print(); [ '\012' ] Previously: MonetDB>chr(10).print(); [ ] This also shows a very important reason for wanting to make this change. Another example which is possibly even worse is chr(0).print(). I ran the pathfinder and sql tests, and only in pathfinder there are 2 tests that are affected (I will appprove them when I check the patch in). This message is a heads up. If you think you might be affected (JDBC, Perl, others?), then maybe you will need to make changes once I check this in. The Mapi library already deals with single-quoted values. -- Sjoerd Mullender
