Reg : Chunk By Chunk To DB
by Chandrasekhar 12 Dec '14

12 Dec '14

Dear Christian I am adding xml to the database using two ways in java 1) LocalSession ls = new LocalSession(context); ls.execute("ADD ","FILEPATH"); 2) ls.add("PATH", new FileInputStream("FILEPATH")); In first case taking time to adding the xml to database,when my xml is big and in databasesize also big.But this case memory consumption is very less. In second case it is adding to database very fast in both the cases.But it is consuming the memory.Is their any way to add xml to db with less memory and as well with performence. Is their any way to add xml with chunk by chunk to the database. MY XML MAX SIZE: 6GB Please do the needful.

Upgrades and version compatibility
by Pascal Heus 12 Dec '14

12 Dec '14

Is there any documentation available around database compatibility across BaseX versions? For example, can I use a 7.6 database with 7.7 / 7.8 / 7.9 / 8.0 etc.? If I opena 7.6 database with 7.9, it may work may can the database still be used with 7.6 if I make any change? I we want to convert a 7.6 database to 7.9 or 8.0, what would be the easiest approach (besides a full reload of the source document, which in some case is not possible)? We have a couple projects running on 7.2 and 7.6 and trying to find a good upgrade strategy. Also, some users have opened these databases with more recent releases and experiencing stability issue so trying to determine if this could be a source of the problems. thanks *P

BaseX 8.0: Updates, User Management
by Christian Grün 10 Dec '14

10 Dec '14

Hi all, Since a while now, BaseX 8.0 is on the agenda, and we are busy finishing all the features requested by you and ourselves. As promised, there will be no changes in the database layout: You can easily move on to 8.0 without needing to migrate your existing data. However, we have decided to discard the old user management in favor of a more up-to-date architecture [1]. Here are some of the most prominent changes: • An XQuery User Module allows you to manage users via XQuery • Permissions can now be manually edited (all credentials will be stored as XML) • Instead of md5, we now use salted sha256 hashes • Additionally, digest hashes are used for the new HTTP Digest Authentication, and for the existing client bindings (cram-md5 was dropped) As a result, credentials of existing databases cannot be migrated to 8.0. Moreover, the existing language bindings will need to be updated. The changes are marginal, so it shouldn't be a big deal [2]. If you want to help us, we welcome you to update your favorite bindings to the latest standard! And as you can guess… The latest snapshot is online [3]. Thanks for your attention, Christian PS: Our BaseX Users Meetup has been confirmed. It will be attached to the XMLPrague conference, and it will take place February 13 in the afternoon [4]. More to come! [1] http://docs.basex.org/wiki/User_Management [2] http://docs.basex.org/wiki/Clients [3] http://files.basex.org/releases/latest [4] http://lanyrd.com/2015/basex/

more thoughts
by Rob Stapper 09 Dec '14

09 Dec '14

Hi Christian, Now I'm still on it, I've another thought; c.q. request. With closures as datastructures we're half way an OOP'ish-implementation. The other half concerns class-methods. Modules work pretty good here, ( now it comes) however it would be nice if some sort of inheritance could be implemented. For example: I store my map:update-function ( see my previous mail) with some other map-sugar functions in "XQR.map"-module, which is just an extension in the BaseX map-module. If I don't want to be put up with both modules in my program, which for obvious reasons is a good attitude, I have to redirect all standard map-function calls in my self defined XQR.map-module to Basex's map-module. But now I find myself programming these redirections, which, for the same obvious reasons, is not an optimal situation. I was wondering if there is or maybe can be created, an easy way to redirect unresolved function calls within a module to a specified module. With or without entering W3C-territory. What's your opinion on this? Rob Stapper --- Dit e-mailbericht is gecontroleerd op virussen met Avast antivirussoftware. http://www.avast.com

Bug in computed attribute constructor
by Hans-Juergen Rennau 08 Dec '14

08 Dec '14

Dear BaseX team, I think there is a bug in the computed attribute constructor. If the name expression evaluates to a value of type xs:string or xs:untypedAtomic and the value contains no prefix, the attribute name should be in no namespace. However, the following code: <node xmlns="http://www.infospace.org/pcollection">{ attribute a1 {'foo1'}, attribute {'a2'} {'foo2'} }</node> yields this result:<node xmlns:ns0="http://www.infospace.org/pcollection" xmlns="http://www.infospace.org/pcollection" a1="foo1" ns0:a2="foo2"/> While @a1 has the expected name, @a2 hasn't. I used the latest snapshot: BaseX 8.0 beta 95b7e5f [Standalone] Kind regards,Hans-Juergen http://www.w3.org/TR/xquery-30/#id-computedAttributes

requests concerning the map-module
by Rob Stapper 08 Dec '14

08 Dec '14

Hi Christian, When processing XML-sources one is most probably going to need internal lookup-tables. The map-module in combination with closures;-) for its mapped data makes a great solution for this. However, the map-key just being just a single atomic value restricts its use or at least leads to some creativeness: - Sometimes one just needs a combined key instead of a single value key. My solution now is to convert the key-values to strings and concatenate them but this is no full-proof method. - Or, when processing XML-data, one wants the key to be an XML-element. For this I use a json-conversion, which works, but I still have to program the conversion. Both situations occur within my project. So, my request is to extend the map-key to allow multiple key-values and XML-elements. Well, now we're on it; why not allow closures as key-values. In that case we've our solution for the previous multiple key value request. How do you feel about this? Oh, now we're on the map-module; an update-function would be great. While processing XML-data one needs to update its lookup-tables often. I use the code below in a module. Maybe it's a candidate for an embedded map-module function. declare function XQR.map:update ( $map as map(*) , $key as xs:anyAtomicType , $init.data as item() , $updateFunction as function(*) ) { map:put( $map , $key , $updateFunction( let $go := function( $entry.data ) { if ( exists( $entry.data)) then $entry.data else $init.data } return $go( map:get( $map, $key)) ) ) } ; Kind regards, Rob Stapper --- Dit e-mailbericht is gecontroleerd op virussen met Avast antivirussoftware. http://www.avast.com

running BaseX 8.0 under OSX 10.6.8?
by C. M. Sperberg-McQueen 02 Dec '14

02 Dec '14

When I attempt to run the copy of BaseX 8.0 I just downloaded under OS X 10.6.8, I get the following error report, which at the moment I am having some trouble deciphering. cmsmcq$ /opt/local/BaseX-8.0/basex/bin/basexgui Exception in thread "main" java.lang.UnsupportedClassVersionError: org/basex/BaseXGUI : Unsupported major.minor version 51.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:637) at java.lang.ClassLoader.defineClass(ClassLoader.java:621) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) at java.net.URLClassLoader.defineClass(URLClassLoader.java:283) at java.net.URLClassLoader.access$000(URLClassLoader.java:58) at java.net.URLClassLoader$1.run(URLClassLoader.java:197) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) cmsmcq$ Is this telling me that BaseX requires a more recent version of Java than I currently have on this machine? Or is it something else? [Yes, I know, I should upgrade my operating system and possibly my hardware ... someday.] Thanks for any help. -- **************************************************************** * C. M.

It was already up for a while but DNS issues made my blog go missing for almost a week. Now it's back. http://xokomola.com/2014/11/18/xquery-origami-2.html The post describes how to do screen scraping using Origami extractors. I'm quite happy with the outcome. --Marc

Fold - HTTP routing library
by Marc van Grootel 01 Dec '14

01 Dec '14

Hi, I would like to announce a new library (very alpha) called Fold. https://github.com/xokomola/fold It is a an HTTP routing library which provides an alternative way to map HTTP requests to XQuery functions. In future I hope to use this together with Origami to build REST services and small web apps. My main goal of announcing this is to get feedback on how to improve this. Currently it is defined on top of RESTXQ but in future this might be handled by a Java extension. There are parts missing still and I strongly advise you not to use this for a serious project. Performance gets bad quite quickly. Performance gains may very well be possible by XQuery refactorings. I basically wrote this as a port from a couple of Clojure libraries. A bit of documentation for this library and for Origami can be found in each project's wiki. Note that I only just started these and they are not complete. I'll be working on this library over the next month to get it into a more usable shape. Happy to receive comments and improvements. --Marc

More Diacritic Questions
by Chris Yocum 30 Nov '14

30 Nov '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi Everyone, I am rather confused again about diacritic handling in basex. For instance, with Full Text turned on a word like athgabáil will match both athgabail and athgabáil with "diacritics insensitive" which is what I would expect. However, if I try to match a word like cúachṡnaidm (with s with a dot above), it will not match without "diacritics sensitive" turned on in the query itself. I am rather confused why it would match in the case of athgabáil but not in the case of cúachṡnaidm. Does anyone know why this is happening and how to make it match like the other match? All the best, Chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iF4EAREIAAYFAlRyFScACgkQDjE+CSbP7HogoQD/eyQT0ioILJv3KHL1cKyNi+Ht a8s0g3Az5o6Uvnniw50A/Reyycsn8YiIY3naEOPuwKydBOUwrYKSe5fjOTqtZyXl =jycQ -----END PGP SIGNATURE-----

How to use ft:search() for querying 2 or more phrases?
by John Best 28 Nov '14

Hi BaseX Team, The subject itself is explanatory. I have following query - ft:search("Articles", ("electromagnetic waves"), map { 'mode':='Phrase' })/ancestor::Doc return $x This query searches for "electromagnetic waves" as a phrase. I want to search another phrase "electromagnetic particles" with the previous phrase. List only those Articles having both these phrases. -- Have a nice day JBest

CSV : escape character feature
by Fabrice Etanchaud 28 Nov '14

28 Nov '14

Dear all, I did not find a way to specify how to escape quotes when importing a csv file with quotes=yes. Here is an example : "12345"|"TOTO LE HERO"|"Toto le héro 3 \"A'' LP"|"67"|"8051"|"4000"|"XX"|""|"LU"|""|""|"ITE"|""||"GB"|""|"20.10" where quotes are escaped with a leading \ (the '' after the A are two single quotes). But it seems BaseX detects quote quote ("") as escaped quote. Could it be possible to have in the future an option to override the default behavior ? Best regards, Fabrice Etanchaud Questel/Orbit

unexpected behaviour
by Rob Stapper 27 Nov '14

27 Nov '14

Hi, I'm playing with the new XQuery 3.1 functions amongst which the JSON-serilization. I would expect all three snippets below to result in the same output but all three give a different result. Snippet 1: ======= declare option output:method 'json'; serialize( <a>test</a> ) Snippet 2: ======= serialize( <a>test</a> , map{ 'method' : 'json'} ) Snippet 3: ======= declare option output:method 'json'; serialize( <a>test</a> , map{ 'method' : 'json'} ) If I do the same with XML-serilization than all three results are the same. Are my expectations correct in this? - Rob --- Dit e-mailbericht is gecontroleerd op virussen met Avast antivirussoftware. http://www.avast.com

Windows startup script problems
by Marc van Grootel 27 Nov '14

27 Nov '14

Hi, I just downloaded the latest snapshot and on Windows I got a problem with the startup scripts. I saw that compared to earlier the way to set JVM options has changed. In my case this was causing problems. When I started the default basexhttp.bat I got: Invalid maximum heap size: -Xmx512m I looked at the batch script and had to change the BASEX_JVM line from set BASEX_JVM=-Xmx512m %BASEX_JVM% to set BASEX_JVM=-Xmx512m Could it be that the extra space after 512m is causing the problem. Probably same issue in other startup scripts. (nice language windows batch file, isn't it ...) --Marc
