Set strip whitespace mode
by Hans-Juergen Rennau 15 Sep '23

15 Sep '23

Dear BaseX folks, question: what is the recommended way of ensuring that an application calling BaseX via command-line (basex ...) uses a certain strip whitespace mode (true or false), if the application is deployed on servers with different BaseX versions? Option -w cannot naively be used, as it toggles the strip whitespace mode, so the effect depends on the version. I have not found out how to determine the version of BaseX reliably, using XQuery or a command. So how can a script decide whether or not to use -w? Thank you for help. Kind regards,Hans-Jürgen

Variable declaration of variable containing a recursive function triggers an error! (golden oldy)
by Rob Stapper 12 Sep '23

12 Sep '23

Hi Christian, I’ve addressed this issue already in feb 2022 and nov 2020. Since I think it is a bug I am coming back on it again. Hopefully with a better formulated argument this time. There is a easy workaround but if code is generated, as in my case, having to change the code manually each time after generation is getting pretty tedious. (and I very much like my code to be consistent) So, why is it that a function-declaration of a function that is recursive doesn’t trigger an self-depending-error and a variable-declaration that has such a function assigned to, does? In the first situation preventing an endless loop is, obviously and rightly so, treated as a programmers responsibility. However in the second situation this responsibility is taken away from the programmer by not even allowing the situation. This is not consistent. Sure, the compiler should and does detect cyclic variable-assignments but that is actually not the case here. Assigning a function to a variable is per definition a non-cyclic assignment. Possible recursiveness in this case should be treated the same as with a function-declaration, that is, as a programmers responsibility. I hope the above makes some sense. Is it worth an effort to address this issue? It would probably make the compiler code even less complex.

I see that docker images have not been updated in over 2 years. I was wondering what the best way to deploy basex in kubernetes is. -- Diego Alcorta dalcorta(a)gmail.com ----------------------------------------------------- "If patience is a virtue, and ignorance is bliss, you can have a pretty good life if you're ignorant and willing to wait" -----------------------------------------------------

Support non-admin user access to database admin interface (DBA)
by Matthew Dziuban 30 Aug '23

30 Aug '23

Hi all, While the subject might sound contradictory, I'm curious what you think about opening up the DBA code to allow non-admin users to access it and perform actions for which they have permissions? I currently maintain and run a fork of the DBA web app at work to make this possible, but I'd love to have the behavior built into BaseX if possible. You can view the changes I've made against BaseX 10.7 here: https://github.com/mblink/basex-webapp/compare/upstream-webapp...webapp-10.7 If you're open to this, I'd be happy to open a pull request with my changes! Thanks, Matt

copy/modify/return and the base URI
by Hans-Juergen Rennau 28 Aug '23

28 Aug '23

Dear BaseX team, I seem to remember that in earlier versions of BaseX a copy/modify/return did not change the base URI of the processed document. However, now it is lost, or more precisely, replaced with the static base URI of the processing XQuery module. Am I mistaken? At any rate it would be very desirable for copy/modify/return to preserve the base URI of the processed document or fragment. Kind regards,Hans-Jürgen

XQuery-Java-Binding: Nullpointer "nsMap" is null (on returning a w3c.dom.Node)
by Andreas Hengsbach | nexoma 28 Aug '23

Hi all, in a Java module I create a "org.w3c.dom.Node" (with java.xml.parsers.DocumentBuilder) and return it to XQuery/BaseX. Since 10.7 I get this exception: # schnipp Exception in thread "main" java.lang.NullPointerException: Cannot invoke "org.basex.util.hash.TokenMap.put(byte[], byte[])" because "nsMap" is null at org.basex.query.value.node.FElem.build(FElem.java:99) at org.basex.query.value.type.NodeType$3.cast(NodeType.java:60) at org.basex.query.value.type.NodeType$3.cast(NodeType.java:55) at org.basex.query.func.java.JavaCall.toValue(JavaCall.java:262) at org.basex.query.func.java.DynJavaFunc.eval(DynJavaFunc.java:90) at org.basex.query.func.java.JavaCall.value(JavaCall.java:81) at org.basex.query.expr.List.value(List.java:230) at org.basex.query.expr.gflwor.GFLWOR.value(GFLWOR.java:92) at org.basex.query.expr.gflwor.Let$LetEval.next(Let.java:146) at org.basex.query.expr.gflwor.GFLWOR.value(GFLWOR.java:92) at org.basex.query.expr.Try.value(Try.java:93) at org.basex.query.expr.List.value(List.java:226) at org.basex.query.expr.gflwor.GFLWOR.value(GFLWOR.java:92) at org.basex.query.expr.List.value(List.java:230) at org.basex.query.expr.If.value(If.java:158) at org.basex.query.expr.List.value(List.java:230) at org.basex.query.expr.Try.value(Try.java:93) at org.basex.query.expr.gflwor.GFLWOR.value(GFLWOR.java:92) at org.basex.query.expr.If.value(If.java:158) at org.basex.query.expr.List.value(List.java:226) at org.basex.query.expr.Try.value(Try.java:93) at org.basex.query.expr.ParseExpr.iter(ParseExpr.java:46) at org.basex.query.scope.MainModule.iter(MainModule.java:48) at org.basex.query.QueryContext.lambda$iter$4(QueryContext.java:357) at org.basex.query.QueryContext.run(QueryContext.java:766) at org.basex.query.QueryContext.iter(QueryContext.java:357) at org.basex.query.QueryProcessor.iter(QueryProcessor.java:95) # schnapp Do I have to create the Node differently now, or is this a bug? nsMap. a map of namespace I guess.

"Expressions must be all updating" puzzle
by Eliot Kimber 21 Aug '23

21 Aug '23

In BaseX 10: In an updating function I have a call to another updating function that uses update:output() to log messages. If that function call is included, BaseX says that expressions must be all updating, but if I remove the call, BaseX is happy. The calling function is: declare %updating %rest:path('/now/rest/analytics/store-latest-acrolinx-users' ) function now:storeAcrolinxUsers() { let $acrolinxMap as map(*)? := try { acrolinx:getUserDataMap() } catch * { util:logToConsole( 'storeAcrolinxUsers' ,``[`{$err:code}` - `{$err:description}`]`` ,'warn' ) } return if (exists($acrolinxMap)) then let $doc as element() := acrolinx:serializeAcrolinxUserMap($acrolinxMap) let $fileName as xs:string := 'acrolinx-users_' || replace($doc/@timestamp, ':', '~') || '.xml' return db:put(analyticsmgmt:getAnalyticsDatabase(), $doc, relpath:newFile('acrolinx/users', $fileName)) }; The offending function is util:logToConsole(), which is declared as: declare %updating function util:logToConsole( $functionName as xs:string, $message as xs:string, $logLevel as xs:string ) { let $logMessage as xs:string := '[' || upper-case($logLevel) || '] ' || $functionName || '(): ' || $message return ( update:output(prof:dump($logMessage)) , update:output($logMessage) ) }; This is declared as an updating function and returns “updating” functions. If I comment out the call to util:logToConsole() in the first function, then BaseX is happy. If I use the non-updating version of logToConsole(), util:logToLog(), then BaseX is also happy. So my question is: why is BaseX complaining about the use of this updating function in an updating function? There must be some subtlety that I’m missing but I have not yet figured out what it is.

Use Bash to construct multi-file form submission
by Eliot Kimber 18 Aug '23

18 Aug '23

This is not strictly a BaseX question but it is in the context of communicating with a BaseX-implemented REST service and I’m hoping someone in this community can answer my question as I’ve not found a solution the interwebs. I’ve implemented a POST method that expects a multi-part form request with multiple files that then loads those files into a database. The files are all related such that I want something close to an atomic commit for the set of files. Thus the multi-file form approach. The REST method works and I can use from the command line using curl, i.e: curl --location http://localhost:9984/now/rest/validation/reports?debug=false \ --form 'files=@"/Users/eliot.kimber/git-basex/product-content-analytics/validation-reports/vancouver/bundle-strategic-portfolio-mgmt_errors_vancouver_2023-08-14T22~11~28Z_1ae692f8_1692054936.xml"' \ --form 'files=@"/Users/eliot.kimber/git-basex/product-content-analytics/validation-reports/vancouver/bundle-tech-technology-industry_errors_vancouver_2023-08-14T22~11~28Z_1ae692f8_1692054971.xml"' What I haven’t been able to figure out is how to construct the equivalent curl command in a bash script, where the script gets a list of flies to load and then constructs the –form parameters. Everything I’ve tried results in a “Warning: Trailing data after quoted form parameter” message or some more utter failure. It must be some subtlety of how to escape the quotes—my googling around produces lots of stack overflow discussions of how to manage the escapes, but nothing I’ve tried has so far worked. My bash approach is simply: curlcmd=”curl --location …” for file in ${files[@]}; do curlcmd+=” --form ‘files=@\”${file}\”’ done And then execute the resulting string: bash -c $curlcmd I have a separate script that successfully constructs a curl call to a companion end point that takes one file: curl \ "--location" "${serverUrl}:${serverPort}/now/rest/validation/report/${fileName}?debug=${debug}" \ "--header" "Content-Type: text/xml" \ "--data-binary" "@${filePath}" And I’m currently just calling this for each file, which is OK. But I’d really like to be able to send a set of files as a single REST call.
