Every query executed in dba Queries causes a global read lock
by Omar Siam 17 Oct '17

17 Oct '17

Hi list! Just discovered sth. unexpected: Every query executed in dba Queries causes a global read lock. Also other (very simple) queries using RESTXQ which use a DB explicit in the query are executed with a global read lock. Is this intentional? Is this just a side effect? I noticed that internally the code I run is wrapped in an xquery:eval. Maybe this causes this lock? Or does every RESTXQ cause a global read lock? I ran into this because I wanted to execute async code using this interface using the jobs module and then wait for the result. This of course locks up as soon as any access to data in dbs is attempted. Best regards Omar Siam

Incorrect result with negative 7-digit number from fn:format-number()
by Andrew Savikas 17 Oct '17

17 Oct '17

Hello, I'm struggling with some odd behavior while trying to format currency amounts. When the number is negative and 7-digits long, the picture string is not working properly. You should (I hope!) be able to replicate the issue in the GUI: format-number(-999999, "$#,##0") *Result:* -$999,999 <-- Expected Result format-number(-9999999, "$#,##0") *Result:* -$9999,999 <-- *Comma is in the wrong place* format-number(-99999999, "$#,##0") *Result:* -$99,999,999 <-- Expected Result Am I missing something here? Thank you!

404

Hi List, a question I have in mind since a long time: I have a Basex serving multiple project sites behind Nginx Redirections. I wrote a servlet for 404 errors in web.xml: <error-page> <error-code>404</error-code> <location>/error404</location> </error-page> and a function: declare %rest:path("/error{$code}") %output:method("html") But if i try to get "http://www.bla.fr/xzxzxzxzxz", basex answers: "No function found that matches the request." How could I inhibit this behavior ? thanks ! -- Ce message peut contenir des informations réservées exclusivement à son destinataire. Toute diffusion sans autorisation est interdite.

How to identify the error when create database is unsuccessful
by Dave Day 13 Oct '17

13 Oct '17

Greetings list, I'm getting the following error when I try to create a new database using the Basex gui on windows. "No text allowed before root element." This is the error I get if I set the parsing option to 'use internal XML parser'. If I uncheck that, I get "Content is not allowed in prolog." The file I am using as input does not have a prolog statement. If I look at the .log folder, there is nothing in there. I suspect that the FTP process I used (microsoft ftp command from a dos window) to move the data from an IBM mainframe to my desktop has done something to the file. Isn't there some way to turn on a diagnostic feature to see exactly what the parsing issue is? I don't see anything in the file before the root element using Notepad. Thanks for any help, -- Dave Day

proc:system ?
by jean-marc Mercier 13 Oct '17

13 Oct '17

Hello BaseX team, I am an extensive user of the proc:system BaseX command (and looking forward for proc:fork !). I am using this command with in-memory arguments, it means that my way of using it is : proc:system("my_exe", $my_arguments_for_exe) $my_arguments_for_exe is an xml node serialized to string by BaseX. As my test are getting more complex, the size of $my_arguments_for_exe are increasing. It seems that we are reaching a limit now, since the compiler refuses to pass arguments : "Stopped at CoDeFi_Interface.xqm, 44/22: [BXPR9999] Cannot run program "C:\Jiheme\scientifique\recherche\CoDeFi\CoDeFi\CoDeFi.exe": CreateProcess error=206, Nom de fichier ou extension trop long " Is there a way to bypass this ? Thank you for your answer, Cheers, Jean-Marc

Storing SQL text as an XML element
by Dave Day 10 Oct '17

10 Oct '17

Greeting list, Is there anything 'special' that needs to be done to an SQL statement to save it as an XML element in BaseX? Create the element, move the text? What happens if the SQL has the "<" or ">" embedded within the text? Regards, -- Dave Day

HTTP module
by Giuseppe Celano 10 Oct '17

Hi, I am accessing a RESTful API via the following command: curl -F data=(a)example.txt -F tokenizer= -F tagger= -F parser= http://lindat.mff.cuni.cz/services/udpipe/api/process > example2.txt I am wondering what the best way is to do that in BaseX. The service also has a URL syntax, as shown in the following example: http://lindat.mff.cuni.cz/services/udpipe/api/process?tokenizer&tagger&pars…. <http://lindat.mff.cuni.cz/services/udpipe/api/process?tokenizer&tagger&pars….> I have tried: http:send-request(<http:request method='get' href='http://lindat.mff.cuni.cz/services/udpipe/api/process?tokenizer&tagger&…'/>) and works perfectly; but I was trying to put the body of the request in http:body, but it does not work: http:send-request(<http:request method='get' href='http://lindat.mff.cuni.cz/services/udpipe/api/process'> <http:body media-type ="string"> tokenizer&tagger&parser&data=Děti pojedou k babičce. Už se těší. </http:body> </http:request>) I could invoke the curl command in BaseX, but maybe there is a more elegant way to send the content of the file (than adding it to the URL). Thanks.
