Database with data on disk shows 0 documents, throws error on optimize all
by Omar Siam 12 May '25

12 May '25

Hi! We had some serious problems with our storage last week and unfortunately that killed one of our important BaseX databases. Is there any way to restore the data? Does BaseX GmbH provide paid data rescue services? The symptoms are: There is data in that database: Mode LastWriteTime Length Name ---- ------------- ------ ---- -a--- 12.05.2025 13:16 25214377 atv.basex -a--- 12.05.2025 13:16 451580 atvl.basex -a--- 12.05.2025 13:16 106065 atvr.basex -a--- 12.05.2025 13:16 131 ftxx.basex -a--- 12.05.2025 13:16 449615 ftxy.basex -a--- 12.05.2025 13:16 697581 ftxz.basex -a--- 12.05.2025 13:59 319 inf.basex -a--- 12.05.2025 13:16 39 pth.basex -a--- 12.05.2025 13:16 28 swl.basex -a--- 12.05.2025 13:16 29798400 tbl.basex -a--- 12.05.2025 13:16 23650 tbli.basex -a--- 12.05.2025 13:16 693232 tokl.basex -a--- 12.05.2025 13:16 105495 tokr.basex -a--- 12.05.2025 13:16 53480811 txt.basex -a--- 12.05.2025 13:16 669153 txtl.basex -a--- 12.05.2025 13:16 166050 txtr.basex -a--- 12.05.2025 13:59 0 upd.basex Inspect reports 0 documents.

Strange behaviour with db:copy and put-value
by Marco Lettere 12 May '25

12 May '25

Dear all, running 11.7 I'm trying to rename some resources that have been inserted into a database with db:put-value(). Uncommenting and executing single lines of the following sequence [1] I get the output in [2] for the first db:list-details but the output in [3] for the second list-details. It somehow has to do with multiple renaming because if I rename the resources one by one this doesn't seem to happen. Could you provide some insight? Thank you, Marco. [1] (:db:create("test"):) (:db:put-value("test", <a/>, "first/a"), db:put-value("test", <b/>, "first/b"):) (:db:list-details("test", "first"):) (:db:rename("test", "first", "second"):) (db:list-details("test")) [2] <resource type="value" content-type="application/octet-stream" modified-date="2025-05-12T12:42:35.403Z" size="7">first/a</resource> <resource type="value" content-type="application/octet-stream" modified-date="2025-05-12T12:42:35.403Z" size="7">first/b</resource> [3] <resource type="value" content-type="application/octet-stream" modified-date="2025-05-12T12:37:24.563Z" size="7">second.basex/a</resource> <resource type="value" content-type="application/octet-stream" modified-date="2025-05-12T12:37:24.564Z" size="7">second.basex/b</resource>

Stemming and Italian
by Marco Lettere 12 May '25

12 May '25

Dear all, as stated in the documentation for fulltext, since I have lucene-3.4.0 jar file in the lib directory of BaseX (and thus in its classpath which is java -cp [...]/basex/BaseX.jar:[...]/basex/lib/custom/*:[...]/basex/lib/*: -Xmx2g org.basex.BaseXGUI) I was expecting the following query to return true() "cammina" contains text "camminare" any word using stemming using language "it" (: tried also with Italian:) But I always get false() with any combination whereas it works neatly with embedded English and German. Ho can I understand if stemming is actually used and in case with what language. Thanks for your support, Marco.

Compatibility of BaseX Java library between versions
by Matt Dziuban 05 May '25

05 May '25

Hello, I run a BaseX server and connect to it in code using the org.basex:basex Java library hosted on https://files.basex.org/maven, specifically using the ClientSession <https://github.com/BaseXdb/basex/blob/11.9/basex-core/src/main/java/org/bas…> and ClientQuery <https://github.com/BaseXdb/basex/blob/11.9/basex-core/src/main/java/org/bas…> classes. I'm wondering about the compatibility between the BaseX server and client versions. For example, if the BaseX server is running v11.8, but my code uses v11.9 of the Java library, am I likely to run into any issues? Thanks in advance, and congratulations on the 11.9 release! Matt

Recovering database in bad state
by Eliot Kimber 01 May '25

01 May '25

I have a database that shows having the expected 2 documents in it in the DBA databases list but when I go to the database in the DBA it shows 0 items. I think this is because the database was being written to and something happened that left it in a bad state. Is there any possibility of recovering this database so it is usable? The practical problem is that it takes several hours to populate this database, so recovering it rather than attempting another multi-hour load would be nice. Here’s what I see for files in the database’s directory on the server: -rw-r--r-- 1 eliot.kimber.adm domain users 73039559 Apr 18 14:50 atv.basex -rw-r--r-- 1 eliot.kimber.adm domain users 7544382 Apr 18 14:52 atvl.basex -rw-r--r-- 1 eliot.kimber.adm domain users 2730980 Apr 18 14:52 atvr.basex -rw-r--r-- 1 eliot.kimber.adm domain users 236 Apr 18 04:17 ftxx.basex -rw-r--r-- 1 eliot.kimber.adm domain users 218072 Apr 18 04:17 ftxy.basex -rw-r--r-- 1 eliot.kimber.adm domain users 1603678 Apr 18 04:17 ftxz.basex -rw-r--r-- 1 eliot.kimber.adm domain users 15 Apr 18 04:17 idp.basex -rw-r--r-- 1 eliot.kimber.adm domain users 15193 Apr 18 04:17 inf.basex -rw-r--r-- 1 eliot.kimber.adm domain users 67 Apr 18 04:17 pth.basex -rw-r--r-- 1 eliot.kimber.adm domain users 28 Apr 18 04:17 swl.basex -rw-r--r-- 1 eliot.kimber.adm domain users 83701760 Apr 18 14:52 tbl.basex -rw-r--r-- 1 eliot.kimber.adm domain users 9 Apr 18 04:17 tbli.basex -rw-r--r-- 1 eliot.kimber.adm domain users 112380335 Apr 18 14:52 tokl.basex -rw-r--r-- 1 eliot.kimber.adm domain users 2829520 Apr 18 14:52 tokr.basex -rw-r--r-- 1 eliot.kimber.adm domain users 1718692 Apr 18 04:17 txt.basex -rw-r--r-- 1 eliot.kimber.adm domain users 351326 Apr 18 04:17 txtl.basex -rw-r--r-- 1 eliot.kimber.adm domain users 285610 Apr 18 02:38 txtr.basex -rw-r--r-- 1 eliot.kimber.adm domain users 0 Apr 18 04:18 upd.basex In the Databases list I see: _temp_lrk_yokohama_link_records<http://mirabel.corp.service-now.com:8984/dba/database?name=_temp_lrk_yokoha…> 2 274 MB 2025-04-18, 14:52:42 But then when I go to the database itself it just say “0 entries”.

inspect:functions
by Rob Stapper 01 May '25

01 May '25

Hi, I want to make use the 'inspect:functions'-function but whatever I do I always get this error: ' [inspect:parse] Stopped at C:/Users/Rob/Projecten/SemanticWorldModel/repo/SWM.main/content/IMPLEMENTATION-DOMAIN/reverseArrayIterator.xqm, 4/27: [XQST0049] Duplicate declaration of static variable .........' It looks like the function traverse all through the module structure following the module imports. And when it encouters a cyclic situation, which is not abnormal within a module structure, the function trigers this error. I think it should just stop on that branche because obviously the model has already been processed. Maybe even, the function should not iterate through the module structure at all, just returning the functions of the requested module. Maybe I'm just doing things wrong here. Can you please shed some light on how to prevent this error when using 'inspect:functions'? Some background for this madness: I want to annotate my FunctionDataStructure, dataStructures as functioncallparameterset, with the name of the module that contains the functions for this type/class of data (class and methods in OO). Thanks in advance for your responce. mvgr. Rob Stapper

Problem in Java extension module
by Nico Verwer (Rakensi) 24 Apr '25

24 Apr '25

Greetings, BaseX creators and users! I am trying to make a custom XQuery function in Java. This works fine in most cases, but it seems to lose namespaces on attributes. The Java code in the function converts the BaseX representation of an element into a `org.w3c.dom.Element` DOM; transforms the DOM, creating a new DOM; sends the resulting DOM element back to BaseX. The problem is quite subtle and hard to explain in a few sentences. Therefore I have made a project demonstrating it, which can be seen on [Github](https://github.com/nverwer/possible-bug-in-BaseX). The project includes Java code and a simple XQuery that demonstrates the problem. I am at the point where I think the problem could be a bug in BaseX, which is why I thought it would be a good idea to post this to the basex-talk mailing list. If someone with more knowledge of the inner workings of BaseX could help me, I would much appreciate. Best regards, Nico Verwer
