BaseX 7.9 problem
by cmarchand＠oxiane.com 23 Jul '15

23 Jul '15

Hello ! I have an exception throw on BaseX 7.9 I've just installed it on a linux box, in /usr/local/basex-79, owned by root, chowned -R a+wr *, and run by another user. Here is the problem : $ /usr/local/basex/bin/basex -d BaseX 7.9 [Standalone] Try help to get more information. > SHOW USERS Exception in thread "main" java.lang.NullPointerException at org.basex.core.Context.perm(Context.java:220) at org.basex.core.Command.execute(Command.java:84) at org.basex.server.LocalSession.execute(LocalSession.java:121) at org.basex.server.Session.execute(Session.java:37) at org.basex.core.CLI.execute(CLI.java:106) at org.basex.core.CLI.execute(CLI.java:90) at org.basex.BaseX.console(BaseX.java:197) at org.basex.BaseX.<init>(BaseX.java:171) at org.basex.BaseX.main(BaseX.java:42) Any help will be appreciated to identify the problem...

basexclient and modules
by cmarchand＠oxiane.com 23 Jul '15

23 Jul '15

Hello ! we would like to execute thru basexclient a xquery script that includes a xquery module : xquery encoding "utf-8"; declare namespace db="http://basex.org/modules/db"; import module namespace om-ll='http://els.eu/ns/efl/offresMetiers/CreateCIActu/lowLevel' at 'lowLevel.xqm'; With basexgui and basex CLI, no problem. But with basexclient, it seems included files are not send to server, so server can not resolve dependencies, and compile xquery. I can understand that compilation must be done on server-side - well, at least optimization - but client could parse the .xq file to check if there are imports, and either push them to server, or throw an error without accessing the server. Is this an issue ? Is there an utility-tool which allows to generates a single script file from a .xq and included .xqm, that I could use before running basexclient ? Best regards, Christophe

Union of maps?
by Graydon Saunders 20 Jul '15

20 Jul '15

Hi -- In BaseX 8.2.1, I have a bunch of maps; the maps may have some overlap of key values. I would like to merge/find the union of all of these maps while retaining all the values associated with each key in the resulting map-of-all-maps. (Combined map? Any word can be wrong, here! :) map:merge() doesn't do this; http://docs.basex.org/wiki/Map_Module#map:merge says "The associated value for each such key is taken from the last map in the input sequence $input that contains an entry with this key." and testing confirms this. Is there a straightforward way to do this that I'm missing? Thanks! Graydon

BaseX Pegging Java Process: How To Diagnose?
by Eliot Kimber 20 Jul '15

20 Jul '15

Using BaseX 8.2.1 HTTP server, not actively performing any queries (but having performed some after restarting the server), BaseX is pegging one of my processors. What can I do to determine what BaseX is doing when it's in this state? Thanks, E. ---- Eliot Kimber, Owner Contrext, LLC http://contrext.com

Re: [basex-talk] More Array Troubles: Syntax Subtlety That I'm Missing

Please ignore my question: apparently I hadn't saved the module that corrected my bug. So sorry for the noise.

More Array Troubles: Syntax Subtlety That I'm Missing
by Eliot Kimber 17 Jul '15

17 Jul '15

I have this recursive function that takes an array as its second parameter: declare function lmm:applyScopesToNames( $keyNames as xs:string+, $keyScopes as array(*), $qualifiedNames as xs:string*) as xs:string* { let $result := if (array:size($keyScopes) = 0) then $qualifiedNames else let $newNames := for $name in $keyNames return for $scopeName in $keyScopes(1) return $scopeName || "." || $name return lmm:applyScopesToNames( $newNames, array:tail($keyScopes), ($qualifiedNames, $newNames) ) return $result }; Testing with this input: let $keyName := "base" $keyScopes := [("s3", "s4"), ("s1", "s2")] This call: let $qualifiedNames := lmm:applyScopesToNames( ($keyName), $keyScopes, ()) Results in the message "Item expected, sequence found: [("s3", "s4"), ("s1", "s2")]." Unfortunately, the BaseX interactive query tool doesn't report the line that produces the message, but the only place I'm passing the full array is in the initial call to the function from my test query. I've also verified that if I pass in [] as the keyScopes parameter then I get the expected result (that is, the value of the 3rd parameter is returned). I've verified that $keyScopes is an array of two sequences and as far as I can tell I'm passing arrays where arrays are expected so I'm not sure what my error is, but there must be one.

Full memory database
by cmarchand＠oxiane.com 16 Jul '15

16 Jul '15

Hello, is there a way to put all the databases in memory ? We have a 30Gb database, serving as repository for XInclude-like resolution, and I want to avoid disk access (I work with Marc Messeant...) Using special JVM, I can allocate many memory, and so want to work only in memory. Is this possible ? Best regards, Christophe

RESTXQ: function loading
by Jérôme Chauveau 15 Jul '15

15 Jul '15

Hi, i'd like to execute a function (which I wrote in an .xqm module) with an fn:function-lookup call. This function has no %rest:path annotation and seems to be unavailable from the current context function list (I inpected it with an inspect:context//function call). Is there a way to "force" its loading? I am currently working with the last BaseX8.2.2 war version. Thanks. Regards, Jérôme -- Jérôme Chauveau - CERTIC-DSI - Campus I Université de Caen Basse-Normandie

Whitespace
by meumapple 14 Jul '15

14 Jul '15

Hi, When I use the file:write function, the whitespaces before an element are deleted (and also the initial whitespace of a string in an element). This is a problem for elements containing text and elements. Is there a way to avoid this? Thanks. J.
