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

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.

Re: [basex-talk] mapping functions
by Imsieke, Gerrit, le-tex 17 Aug '23

17 Aug '23

Hi Graydon, Replying to the list for posterity. I hope you don’t mind. When you dynamically evaluate an expression (xquery:eval(), job:eval(), …), you start with the default values of the static context [1]. Nothing of the XQuery module from which you evaluate the expression is known (unless supplied by binding, but ordinary function declarations are not amenable to binding), therefore no risk of circularity. As stated in the table in [1], you can use module import [2] to augment this clean slate. In particular the module’s function declarations/signatures will be available then. If you don’t want the dynamically evaluated expression to import the whole module, you can store functions into variables and supply these variables to the evaluation through bindings. Haven’t tried it yet.

Accessing BaseX server on remote machine
by Furst, Thomas 17 Aug '23

17 Aug '23

Hello, I am attempting to use BaseX from a central location on our network so that all team members can access it. I am using the Python Client to achieve this. Everything works fine when the host is entered as 'localhost'. Once I change it to the remote host name, I am getting a time out error reported back: TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond On the remote machine (Windows 10 Pro for Workstations) I have opened port 1984 in the firewall on both the inbound and outbound. Can someone help me understand what I may be doing incorrectly? Or what I may have overlooked doing that is also required? Thank you, Tom Furst

mapping functions
by Graydon Saunders 15 Aug '23

15 Aug '23

Hello -- I have various databases that will be run through the same code after their contents is regularized. So the only different function is the one used for regularization. This can be handled by writing a wrapper function and passing in a label to say which function to use, but I was wondering if there's a way to do it in the configuration map directly. The configuration map exists as a text file and gets run through xquery:eval() at the start of the process. declare namespace abc='http://some/uri'; 'regularizationFunction': map { 'typeOne': abc:regularizationOne#1, 'typeTwo': abc:regularizationTwo#1 } doesn't work, because the abc functions aren't known at evaluation time. These functions are defined in the library module that's evaluating the configuration file but xquery:eval() doesn't know that. I don't see a way to use bindings to get around this. Is there a way to map a locally-defined function reference so xquery:eval() will recognize it? thanks! Graydon -- Graydon Saunders | graydonish(a)fastmail.com Þæs oferéode, ðisses swá mæg. -- Deor ("That passed, so may this.")
