empty() behaves differently on 7.8.2
by Marco Lettere 08 May '14

08 May '14

Hello all, I'm pretty puzzled by the following fact. On version 7.8 the following code returns true() (which btw is what I expect to be right) let $a := () return empty($a) whereas in 7.8.2 it returns false(). Any advice? Thanks, M.

Hi, I can't figure out why the attached xquery-program triggers an error. Am I doing naughty things or is it a bug? Regards, Rob --- Dit e-mailbericht bevat geen virussen en malware omdat avast! Antivirus-bescherming actief is. http://www.avast.com

7.8 MAINMEM option
by Maximilian Gärber 07 May '14

07 May '14

Hi, I am running some queries against file based and main-memory dbs for comparison. Creating the main-memory db via xquery (declare option or pragma) did not work: declare option db:mainmem 'true'; or (# db:mainmem true #) Via command line it works: set mainmem true Only the db won't be listed and seems to be dropped after I open another db on the command line. I had expected the main-memory db to be treated like other dbs (e.g. being there as long as I don't drop it or stop the server) Is this behaviour on purpose? Regards, Max

7.8.2 Updating function items
by Marco Lettere 06 May '14

06 May '14

Hello all, after switching to 7.8.2 we started to get this error: XUST001 Updating function items are not yet supported when passing an updating function as a value. This used to work neatly from 7.6 at least onwards. I must admit that I'm pretty surpirsed and I'd like to ask where ni the docs I could get more info on that. Thanks. Regards, Marco.

Any news regarding increasing maximum node count?
by David Rudel 04 May '14

04 May '14

Hello, I found in the archive an email indicating that there were nebulous plans to dramatically increase the total number of nodes that a database could accommodate, from 2 billion to 8 quintillion. Are these plans still in the "nebulous" stage, or is there a more specific timeframe in mind? -David -- "A false conclusion, once arrived at and widely accepted is not dislodged easily, and the less it is understood, the more tenaciously it is held." - Cantor's Law of Preservation of Ignorance.

Customized, Persistent Hashes?
by David Rudel 02 May '14

02 May '14

Hello, Imagine you have data on 100000 test subjects. For every test subject there are 2 data files. For example, one might be a data file describing the actions of a test subject as he went through an obstacle course and the other data file may be time-stamped readings of the subject's heartbeat and breathing rates during the time. These are kept in separate files because the data differs in structure and paradigm (one is event-based the other is a time log). Queries run against such a data base will very frequently want to match up events in one data file to timestamped biometric data in the other for the same student. My question is whether there is a way to set up a persistent pairing of these two files so that any query run against the database knows of this natural connection without it having to be explicitly built each time. For example, it would be nice to create two persistent maps $events and $bio so that the keys of the $events map are document nodes of the data files recording actions students make in the obstacle course and the values are document nodes for associated biometric data, and then $bio is the reverse lookup. Is it possible in BaseX to create a persistent, user-defined hash that is stored and available without needing to be rebuilt to all queries run against a database?

Is there a way to identify an inline function in BaseX?
by Rob Stapper 01 May '14

01 May '14

Hi, In my xquery-program I need to identify an inline function. ( it's a generalized function with a specialized inline function as parameter. The generalized function has to determine which type it's dealing with) I tried annotations but the inspect:function( $f) function doesn't give anything away in case of an inline-function. See attachment. Is there a way to identify inline-functions? Even the namespace of the inline-function would be enough.
