Fwd: Re: functionParameterTyping issue
by Rob Stapper 20 May '25

20 May '25

Hi Christian, Good news, I hope. The problem with the dynamic typecasting is not as much a typecasting-issue but an issue with recognizing derived functions. The problem is that derived functions are treated as functioncalls where it shouldn't. I can remenber that once there was an issue with the parity of derived functions. It is something like that. attached some demos: [referentialDemo.xq] shows that dynamic and strict typing works within version-11.9 [buggyDemo.xq] shows that dynamic and strict typing fails in case of derived functions. [workingDemo,xq] show the workaround. Thought you would like to know what the issue is.

Once correctly validated the data wil be stored as XML and wil be garanteed to be a string (in this case).

If there is a (hidden) dependency in the semantics in your code that $p will always be a map if $n is "a", it is something the complete cannot »guess«. In those cases, it is better to omit type declarations in your code. The reason is that the optimizer will also rewrite and simplify those parts of your code that may not be evaluated at runtime. > > > > Hope this helps, > > Christian > > > > > > > > > > > > > > > mvgr. > > Rob Stapper > mvgr.

11.9 doc() not working with DOCTYPE declaration
by Graydon Saunders 15 May '25

15 May '25

Hello -- I'm on linux, using 11.9 and using 20:59 graydon % java -version openjdk version "21.0.7" 2025-04-15 OpenJDK Runtime Environment (Red_Hat-21.0.7.0.6-1) (build 21.0.7+6) OpenJDK 64-Bit Server VM (Red_Hat-21.0.7.0.6-1) (build 21.0.7+6, mixed mode, sharing) If I use the basexgui "Create DB" dialog and the internal parser, I can load the whole folder without error; I get the expected DB and the named entities in the content have been resolved. (These are effectively HTML 4 entity names, so that's not completely guaranteeing that the DTD in the DOCTYPE is being found and parsed somewhere.) If I use the doc() function with an absolute file system path to one of the same files that loaded into the DB just fine, I get an error. I get the same error if I try to switch off the internal parser and set a catalog. It's at least several files in the folder that loads fine as a DB. All of this works fine with 11.8; whatever changed changed in 11.9. The error is: Could not execute XQUERY doc('/home/graydon/GeneralCode/git/cpc-conversion/Chapter/BU4372-14A.xml'): Improper use?

xqj-api library
by Lyn Elisa Goltz 14 May '25

14 May '25

Hi all, BaseX is an excellent tool, and we are interested in integrating its API into our open-source project. Our project is licensed under the AGPL-3.0, and we want to ensure license compatibility with all the libraries we use. Unfortunately, BaseX depends on the xqj-api library, for which neither a license nor source code appears to be available. The main concern, therefore, is the unclear provenance of this dependency. Could you please provide the license information or the source code for this library? Best regards, Lyn -- l a t / l o n GmbH Im Ellig 1 53343 Wachtberg, Germany phone ++49 +228 24 333 784 http://www.lat-lon.de http://www.deegree.org lat/lon gesellschaft für raumbezogene informationssysteme mbH Registergericht: Amtsgericht Bonn, HRB 13042 Geschäftsführer: Jens Fitzke und Torsten Friebe

Database with data on disk shows 0 documents, throws error on optimize all

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?

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”.
