[News] AssociateLists

[Kor G. Begeman]

L.S.

We discovered a bug in the flat_db code of astrowise about 8 months ago.
This was repaired but we forgot to test whether there was any effect on
the already converted databases. Last week we found that it did matter!
The effect is that the order in which the sourcelists have been 
associated got lost while converting to a flat_db last year. This 
happens more or less at random so it was difficult to detect.
Willem-Jan Vriend and myself have created a script that recalculates the 
order and saves the order when appropriate. This script has been run on 
the Groningen database (db.astro.rug.astro-wise.org) already, the other 
databases will follow shortly.
The AssociateList methods affected by this bug are count_from_flag, 
count_from_members and get_data, so if you used those routines on 
AssociateLists created before march 2007 you might have gotten wrong 
results.

We are sorry for the inconvenience,


Regards,


Kor
