Re: [Monetdb-developers] [MonetDB-users] COPY INTO on aggregate queries crashes MonetDB
by Martin Kersten 04 Jan '09

04 Jan '09

Dear Peter, The problem mentioned could be reproduced. It is clearly a bug and registered as such in test copy-count.SF-2485215.sql. It seems a bug in the code generator of SQL. The progress can be followed in the sourceforge bugtracker. Thanks for using the MonetDB package and helping to improve its quality. regards, Martin Peter Farkash wrote: > Hi, > > When I use COPY INTO with a count query, monetDB crashes. > For example: > > copy select count (*) into 'C:\\copyinto.txt' using delimiters ','; > > Gives me the following result and kills the server: > > MAPI = monetdb@localhost:50000 > ACTION= read_line > QUERY = copy select count (*) into 'C:\\copyinto.txt' using delimiters ','; > ERROR = Connection terminated > > The same happens if I use sum, average, etc. On normal queries the copy into > works just fine. > I am using v5.8.2, and am getting the crash both when using mclient and the > MAPI programming interface. > > Any ideas? >

[Monetdb-developers] MonetDB at Ohloh
by Marcin Zukowski 03 Jan '09

03 Jan '09

Dear MonetDB Devs, As a pre-xmas present, I wanted to update MonetDB site on Ohloh.net - a site that has an ambition (and maybe a chance) to become a central information repository about FOSS projects and developers: https://www.ohloh.net/p/10306 Unfortunately, the code-analysis part of the site does not seem to like the 'sql' module, as it hangs during checking out its history: https://www.ohloh.net/p/10306/enlistments I contacted the Ohloh team, and it seems the error occurs at the following command: ~$ cvsnt -d :pserver:anonymous:@monetdb.cvs.sourceforge.net:/cvsroot/monetdb checkout -D'2001/06/07 13:41:21Z' -A -d'monetdb' 'sql' cvs checkout: Updating monetdb ... cvs [checkout aborted]: invalid change text in /cvsroot/monetdb/sql/src/odbc/driver/Attic/statement_dump.c,v If you think being properly visible on Ohloh is worth it, perhaps this is something some local CVS expert could investigate ;) Otherwise, we can remove the 'sql' module and hope the other ones work properly. cheers, Marcin

The order of attributes is only determined by the very implementation and (physical) order of input data, and can hence change. If it happens to differe between the MPS & ALG back-end for (some) StandOff tests, we could consider approving back-end specific (ALG or MPS) stable output for these tests.
