RESTXQ oddity?
by Murray, Gregory 29 Jan '24

29 Jan '24

Hello, I’m trying to build my first BaseX web application. I’ve got a RESTXQ function for returning static files to the browser, and other RESTXQ functions corresponding to URLs in the web application. The function for static files is based on the one in DBA: (:~ Returns the specified static file to the browser as binary data. :) declare %rest:GET %rest:path('theocom/static/{$dir=.+}/{$file=.+}') function c:file($dir as xs:string, $file as xs:string) { let $path := file:base-dir() || 'static/' || $dir || '/' || $file return ( web:response-header( map { 'media-type': web:content-type($path) }, map { 'Content-Length': file:size($path) } ), file:read-binary($path) ) }; Another function returns the home page for the web application. That page works just fine. The HTML document gets returned to the browser, and the static CSS and image files are sent to the browser successfully. (:~ Returns the home page for the entire web application. :) declare %rest:GET %rest:path('theocom') %output:method('html') %output:html-version('5') function c:home() { let $params := c:http-params() return ( c:extra-response-headers(), home:get-home-page($params) ) }; I have another RESTXQ function that corresponds to a URL that goes deeper into the web application: (:~ Returns a page listing contributors (libraries whose content we've imported), for browsing. :) declare %rest:GET %rest:path('theocom/contributors/{$alpha=[a-z]}') %output:method('html') %output:html-version('5') function c:browse-contributors($alpha as xs:string) { let $params := map:merge( ( map:entry("browse", "contributor"), map:entry("alpha", upper-case($alpha)), c:http-params() ) ) return ( c:extra-response-headers(), browse:contributors($params) ) }; The problem I’m having is that on this page, the browser returns 404 for the static files, even though the code for the HTML <head> where the CSS files are linked is identical to the home page. Am I doing something wrong, or is the BaseX RESTXQ implementation doing something unexpected? Thanks, Greg Gregory Murray Director of Digital Initiatives Wright Library Princeton Theological Seminary

Tim, I'm on an M1 MacBook Air and Cmd-V works for me in the GUI exactly as normal on macOS. Interestingly Ctl-V doesn't. I build BaseX as an app[1] but I just tried double clicking the .jar file directly and Cmd-V still worked. I wonder if the JDK has an impact? I run the Amazon Corretto version.

Consistent NPE loading content on one server, other server works
by Eliot Kimber 24 Jan '24

I have two servers running the same code, both on 10.7. I have a REST API handler that takes data as input and stores it in a database, applying some preprocessing to the data first. The data successfully loads on my dev server and consistently fails on the production server, with this Java failure: [INFO] Posting "/Users/eliot.kimber/git-basex/product-content-analytics/analytics/adobe/adobe-analytics-Utah_Pages_Viewed_Aug2023-clean.csv" [INFO] as filename "adobe-analytics-Utah_Pages_Viewed_Aug2023-clean.csv" [INFO] to Mirabel server "http://mirabel.corp.service-now.com:9984"...

function prof:dump not working
by DK Singh 22 Jan '24

22 Jan '24

Hi, I am using BaseX 9.5 and we are using the prof:dump() function for debugging code and data. When a query is run in the BaseX GUI, the output of prof:dump() is shown in the info view. When we are calling this function in XQUERY and try to print output of prof:dump() in the log then it is not printing anything. As per BaseX documentation, if LOGTRACE is 'ON' and BaseX is being used as a web-application, then the output of prof:dump() function gets logged in database logs. Checked on the server, LOGTRACE is 'ON' but the output is not getting logged in log file.. Also we try it to store output prof:dump() in a variable and print it into log file but not working let $_Logs := prof:dump($work/@id || ' (' || $work/*:titleSet/*:title[1] || ')', 'Excluded from output, as no media found: ') return admin:write-log('output of function prof:dump is: '|| $_Logs) Can you please suggest how we can capture output of function prof:dump() in a XML format or in the BaseX log file? Thank You Dharmendra

GUI feature request: paste into search boxes
by Thompson, Timothy 17 Jan '24

17 Jan '24

Hello, In the BaseX GUI, it’s not possible (as far as I can tell) to paste a copied value into search boxes. Not being able to do so can be inconvenient, for example, when searching for a string like a UUID in result output, etc. Is lack of support for pasting intentional, or am I missing something? Thanks in advance, Tim -- Tim A. Thompson (he, him) Librarian for Applied Metadata Research Yale University Library www.linkedin.com/in/timathompson<http://www.linkedin.com/in/timathompson>

Processing stack traces in XQuery code
by Omar Siam 15 Jan '24

15 Jan '24

Hi, Until 10.6 one could find the stack trace of an error in $err:additional. This feature is now gone from BaseX and the documentation. I made my life much easier with reporting stack traces on errors in RestXQ endpoints. Now I don't see how to get that information anymore. Any advice how to get this functionality back?

Corrupt data base not recognized by inspect
by Jürgen Schwenk Büro 15 Jan '24

Hello, in our application we "produced" a corrupt data base caused by a power fail. On restart we check data base using the "inspect" command to detect failures, creating new empty data base if found one. The attached data base seems OK using "inspect", but accessing the data base we get an exception. Perhaps this may help to make "inspect" more reliable.
