[Monetdb-developers] Re: [MonetDB-users] AMD64 version of MonetDB for Windows?
by Peter Boncz 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.

[Monetdb-developers] MonetDB::CLI: MapiLib alternatives
by Steffen Goeldner 15 Nov '05

15 Nov '05

I'd like to add a more perlish layer around MapiLib (working title: MonetDB::CLI). This may look like: my $Cxn = MonetDB::CLI->connect( ... ); my $Req = $Cxn->query('select * from env'); while ( my $Cnt = $Req->fetch_row ) { print $Req->fetch_field( $_ ) for 0 .. $Cnt-1; } Still much in the spirit of Mapi, but handles are now objects (with destructors), functions are methods and the methods can throw exceptions. Once we have such an interface, additional implementations are possible. For instance, a XS module could skip the MapiLib layer and use libMapi directly. Later on, an implementation for MCL will be added (I hope) - either in pure perl or on top of libMCL (in case such a library will emerge). Of course, I'd like to use this new interface from DBD::monetdb to be able to choose between various implementations and to ease the transition to MCL. On the downside: additional modules means additional installation efforts. Especially the people resposible for the RPM's will be affected. If this sounds too screwy, it's now the chance to stop me ;-) Steffen

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

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?
