Hello everyone, Is there a way to run BaseX with high availability in a cluster? If not, are there any plans to do so? Best regards, Andreas

http:send-request() call emits certificate error
by Yitzhak Khabinsky 09 Dec '25

09 Dec '25

Hello, Using BaseX 12.0 All of a sudden I started to get the following error while calling http:send-request(): [experr:HC0001] SSL: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target XQuery repro: let $uri := "https://giswspro.miamidade.gov/ArcGIS/rest/services/MDPD_Locators/MDPDGeoAd…" return http:send-request(<http:request method='GET' status-only='true' json='format=xquery,lax=true'/>, $uri) By the way, the same error shows up for any URIs. The following SSL validator shows no issues with the certificates, or their chains: https://decoder.link/sslchecker https://decoder.link/sslchecker/giswspro.miamidade.gov/443 Also, the $uri is public, so it is testable on your side. Regards, Yitzhak Khabinsky

store:read within an updating function
by Rob Stapper 07 Dec '25

07 Dec '25

Hello Christian, Allthough the store:read function returns an empty sequense I found that it still triggers the error: 'expressions must all be updating ....', when used within an updating function. I guess this error is unnecesary. The workaround is quite easy by using a void function[1] [1] store:read( $name) => void() mvgr. Rob Stapper

Issue with request:parameter-map and repeated query parameters
by Tom De Herdt 15 Nov '25

15 Nov '25

Hello, I’ve encountered an issue with the new request:parameter-map function in BaseX. It throws an error when called with a query string that contains repeated parameters, such as ?a=1&a=2: [SERE0023] Value has more than one item. Is this behavior expected? As far as I know, query parameters may be repeated. For example, this can occur when submitting a form with checkboxes using the GET method. Additionally, JavaScript provides the URLSearchParams.getAll(<name>) method, which returns an array of values for a given parameter <name>. Wouldn't it be more logical for request:parameter-map to also return an array in such cases? I’ve tested this issue with BaseX 12 on Windows, using the following RESTXQ function: declare %rest:GET %rest:path("test") %output:method("json") function page:test() { request:parameter-map() }; Any insights are appreciated. Regards, Tom De Herdt

load-xquery-module
by Rob Stapper 11 Nov '25

11 Nov '25

Hi Christian, I'm experimenting with dynamic modul loading using: 'load-xquery-module'. I have a few questions concerning this function: - Does this function cache the loaded modul like "import module" does? If I interpret the profiling data correcty, it does not. If so is it possible to also cache dynamicly loaded modules? - "location-hints" of this function accepts a set of locations. It seems that all these locations must contain a module with the given modul-uri. I would expect the one would be sufficient. What is the idea behind this locationset? Thanx in advance for your response. mvgr. Rob Stapper

Processing XInclude "On-Demand" in BaseX
by Josef Thorne 07 Nov '25

07 Nov '25

I was wondering how people are using XInclude in BaseX. Currently, if I load a document into BaseX, XInclude is processed on-load. What if I want to do inclusion "on-demand" in the database context? For example, if I have a template for a web page and wanted to use XInclude to grab something from the database and fill it in when you load the page. One could just use an xquery-based template in that particular example, but there are other cases where this is useful. It was not obvious to me reading the documentation how you're intended to do that, if it is possible. Thanks!

BaseX fiddler is cutting off its Context pane
by Yitzhak Khabinsky 06 Nov '25

06 Nov '25

Hello, I am using BaseX fiddler: https://fiddle.basex.org/#/ And I love it. The fiddler recently got improved with the "Line Numbers" support for both panes: - XQuery - Context Unfortunately, the Context pane is cut off at the bottom If the XML sample is large enough, its end is invisible. Please fix it. Regards, Yitzhak Khabinsky

remove type check?
by David Birnbaum 03 Nov '25

03 Nov '25

Dear BaseX-Talk, I notice in the BaseX GUI that when I execute an XQuery script that includes type checks (e.g., *let $x as element(stuff) := <stuff/>*) the compilation report tells me that BaseX removes the type checks. How should I understand this removal? I can see that BaseX is performing type-checking because if I specify the wrong type, an error is thrown. I'd be grateful for any insights anyone can provide about what the "remove type check" messages mean? Best, David

Invisible XML doesn't accept lazy strings
by Josef Thorne 03 Nov '25

03 Nov '25

It seems that the invisible XML function can't accept a lazy string. It causes it to have a casting exception. A workaround I found is to serialize the lazy string before passing it to the function with fn:serialize's text method. > > let $grammar := file:read-text("basex/data/lcl_grammar.ixml") return fn:invisible-xml($grammar) Full stack trace: Version: BaseX 11.8 Java: Ubuntu, 21.0.8 OS: Linux, amd64 Stack Trace: java.lang.ClassCastException: class org.basex.query.value.item.StrLazy cannot be cast to class org.basex.query.value.item.Str (org.basex.query.value.item.StrLazy and org.basex.query.value.item.Str are in unnamed module of loader 'app') at org.basex.query.func.fn.FnInvisibleXml$Generator.generate(FnInvisibleXml.java:72) at org.basex.query.func.fn.FnInvisibleXml.item(FnInvisibleXml.java:51) at org.basex.query.func.fn.FnInvisibleXml.item(FnInvisibleXml.java:32) at org.basex.query.expr.ParseExpr.value(ParseExpr.java:54) at org.basex.query.expr.ParseExpr.iter(ParseExpr.java:49) at org.basex.query.expr.Pipeline$1.next(Pipeline.java:66) at org.basex.query.scope.MainModule$1.next(MainModule.java:65) at org.basex.query.QueryContext.next(QueryContext.java:387) at org.basex.query.QueryContext.lambda$cache$6(QueryContext.java:599) at org.basex.query.QueryContext.run(QueryContext.java:738) at org.basex.query.QueryContext.cache(QueryContext.java:579) at org.basex.query.QueryProcessor.cache(QueryProcessor.java:120) at org.basex.core.cmd.AQuery.run(AQuery.java:82) at org.basex.core.Command.run(Command.java:233) at org.basex.core.Command.execute(Command.java:93) at org.basex.gui.GUI.execute(GUI.java:430) at org.basex.gui.GUI.lambda$execute$5(GUI.java:375) at java.base/java.lang.Thread.run(Thread.java:1583)

Hi BaseX team, I am writing to report a possible bug for the AUR package of BaseX. For context, my environment is Omarchy/Arch Linux, and the command I am invoking is 'yay -S basex'. Error: install: cannot stat 'img/logo_256.png': No such file or directory ==> ERROR: A failure occurred in package(). Aborting... -> error making: basex-exit status 4 -> Failed to install the following packages. Manual intervention is required: basex - exit status 4 Investigation: Looking on the upstream GitHub source I couldn't find any 'logo_256.png' file. Please let me know if I can provide any more info to help address this error. Thank you for reviewing my issue. - Christian
