[Monetdb-developers] FYI: DBD::monetdb test suite via MonetDB ODBC Driver

by Steffen Goeldner

FYI, I'm using the DBD::monetdb test suite to test the MonetDB ODBC Driver: set DBI_DSN=dbi:ODBC:driver=MonetDB ODBC Driver dmake test Here is the test summary: Failed Test Stat Wstat Total Fail Failed List of Failed --------------------------------------------------------- t\02cxn.t 5 1280 8 4 50.00% 7-8 t\12bind.t 1 256 6 1 16.67% 3 t\13count.t 16 4096 30 16 53.33% 12-27 t\23null.t 255 65280 14 22 157.14% 4-14 1 test and 2 subtests skipped. Failed 4/22 test scripts, 81.82% okay. 30/382 subtests failed, 92.15% okay. In light of all the additional layers, this is an unexpected good result. (Admittedly, my tests are not very aggressive.) And, even better, all is on the mend: t\02cxn.t This is a bug in DBD::ODBC: <http://www.xray.mpe.mpg.de/mailing-lists/dbi/2005-02/msg00061.html> fixed in svn: <http://svn.perl.org/viewcvs/modules/dbd-odbc/trunk/dbdimp.c?rev=858&r1=561&…> t\12bind.t This is bug #1229018: <http://sourceforge.net/tracker/index.php?func=detail&aid=1229018&group_id=5…> t\13count.t This is a bug in DBD::ODBC. It looks like DBD::ODBC doesn't expect that an ODBC driver is able to return the number of rows of a result set. t\23null.t This is bug #1225455: <http://sourceforge.net/tracker/index.php?func=detail&aid=1225455&group_id=5…> Steffen

[Monetdb-developers] MonetDB.conf contains path on developer's machine

by Roger Erens

I don"t know whether MonetDB.conf in CWI\MonetDB\etc is used, but it contains the following lines: # Where MonetDB is installed prefix=C:\Documents and Settings\sjoerd\My Documents\src\MonetDB\NT exec_prefix=C:\Documents and Settings\sjoerd\My Documents\src\MonetDB\NT Roger

[Monetdb-developers] (no subject)

by Roger Erens

Hi, I had some problems installing MonetDB-4.8.0 on MS Windows XP: the Duesseldorf sourceforge mirror still serves the installer that misses the pqueue stuff. Removing the wrong version via the Add or Remove Programs left a filled folder CWI in the Program Files folder and also a filled folder in my home folder's Application Data folder called MonetDB. Only after removing these and using the installer from the Paris sourceforge mirror I was freed from a lot of strange messages. All in all, the installer should have its version number upped, I think. Hopefully this will lead to up-to-date mirrors. Also, the installer should notify the user of the old files and folders, giving the choice of backing those up, or overwrite them, or whatever seems best. ===================================================================== Choosing MonetDB SQL Server and MonetDB SQL Client from the Start Menu: # Monet Database Server V4.8.0 # Copyright (c) 1993-2005, CWI.

Perhaps it works better for you in this case if you use the xquery language, instead of mil from your PHP script.

You might need to connect using xquery otherwise, but I'm not sure on that.

In PHP 4, OnUpdateInt is declared in Zend/zend_ini.h, in the same block which also declares OnUpdateString. Note that in your output there is no indication that OnUpdateString is not defined. zend_ini.h is include by php_ini.h which is included by php_monetdb.c. -- Sjoerd Mullender

[Monetdb-developers] license issues

by Sjoerd Mullender

There is a problem with the MonetDB and Pathfinder licenses. - The new (1.1) license is not yet available on the main web site; - On the staging web site (stem), the license is available with the wrong URL: .../Legal/MonetDBLicense-1.1/index.html instead of .../Legal/MonetDBLicense-1.1.html. I don't know whether the Development that is also stuck into the stem URL is a problem (that depends on how the URLs get translated when this moves to the real web site), but the ending is certainly a problem. The URL must end with MonetDBLicense-1.1.html and not MonetDBLicense-1.1/index.html. And the same for the Pathfinder license. -- Sjoerd Mullender

[Monetdb-developers] About MonetDB's modules

by Rodrigo Schmidt

Hello, I am PhD student at EPFL, Switzerland, and I am working on database replication. I just started looking at MonetDB and I have a simple doubt. Are modules like the SQL module written in MIL or in C/C++? I downloaded the sources of the SQL front end and I found some files whose extension is ".mx" and which seem to implement the SQL translator into MIL. The code looks pretty much like C++. Moreover, I read somewhere in your web page that two-phase-locking is implemented outside the database kernel. Where exactly is it implemented for the SQL front end? Thank you very much in advance! Best regards, Rodrigo Schmidt
