unexpected behaviour
by Rob Stapper 27 Nov '14

27 Nov '14

Hi, I'm playing with the new XQuery 3.1 functions amongst which the JSON-serilization. I would expect all three snippets below to result in the same output but all three give a different result. Snippet 1: ======= declare option output:method 'json'; serialize( <a>test</a> ) Snippet 2: ======= serialize( <a>test</a> , map{ 'method' : 'json'} ) Snippet 3: ======= declare option output:method 'json'; serialize( <a>test</a> , map{ 'method' : 'json'} ) If I do the same with XML-serilization than all three results are the same. Are my expectations correct in this? - Rob --- Dit e-mailbericht is gecontroleerd op virussen met Avast antivirussoftware. http://www.avast.com

Windows startup script problems
by Marc van Grootel 27 Nov '14

27 Nov '14

Hi, I just downloaded the latest snapshot and on Windows I got a problem with the startup scripts. I saw that compared to earlier the way to set JVM options has changed. In my case this was causing problems. When I started the default basexhttp.bat I got: Invalid maximum heap size: -Xmx512m I looked at the batch script and had to change the BASEX_JVM line from set BASEX_JVM=-Xmx512m %BASEX_JVM% to set BASEX_JVM=-Xmx512m Could it be that the extra space after 512m is causing the problem. Probably same issue in other startup scripts. (nice language windows batch file, isn't it ...) --Marc

Hi, I am trying to output some html that have php instructions, and the instructions keep showing as comments. For example: <body> <?php include 'footer/index.html'; ?> </body> Show up as: <body></body> Example: *declare* %rest:path('/cms/ehtml2html5') %rest:GET %output:method("html") %output:html-version("5.0")... *function* *xhtmlsrc:view-html5*(){ <body> <?php include 'footer/index.html'; ?> </body>}; What am I missing? -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com

Http-module error response-bodies always returned as string
by Johan Mörén 25 Nov '14

25 Nov '14

Hi I have a REST service that communicates details about any errors that occurs during execution via a an XML-payload in the response body. I have noticed that the http-module ignores the content-type header of the response if the status-code is > 399. Then it is flagged as being in error and in HttpPayload this line forces the content type of the body to text/plain HttpPayload.java // error: use text/plain as content type final String ct = error ? TEXT_PLAIN : utype != null ? utype : contentType(ctype); Overriding the content type via the override-media-type attribute of http:request doesn't help either in this case. Is there any special reason that error response-bodies are handled in this way? To my knowledge it is very common that REST services provides error information by sending it in the response body. I guess that changing the default behaviour might break existing implementations. But perhaps an additional attribute in the http-request could flag that the media-type of the content-type should be used even with error-responses. Or perhaps via an additional option in the http:send-request() function. Exampel of request and response where this error occurs. Request: http:send-request(<http:request override-media-type="application/xml" href="{'http://localhost:9595/sequencegenerator/objectInstanceId/' || '0'}" method="get"/>) Response: <http:response xmlns:http="http://expath.org/ns/http-client" status="400" message="Bad Request"> <http:header name="nbrOfIds" value="0"/> <http:header name="typeOfId" value="objectInstanceId"/> <http:header name="Transfer-Encoding" value="chunked"/> <http:header name="breadcrumbId" value="ID-2013M-2-local-61198-1416819131884-37-54"/> <http:header name="User-Agent" value="Java/1.7.0_45"/> <http:header name="Accept" value="text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2"/> <http:header name="Content-Type" value="application/xml"/> <http:header name="Server" value="Jetty(8.1.15.v20140411)"/> <http:body media-type="text/plain"/> </http:response><faultResponse><errorMessage>number of ids must be a positive integer larger than 0</errorMessage></faultResponse> Regards, Johan Mörén

Re: [basex-talk] best way to process a collection
by Christian Grün 25 Nov '14

25 Nov '14

Hi Peter, > In this case there are about 23k documents. My approach is given in the attached file. I have a basex client and server running and also an apache tika server. it's all on a 32 bit machine so heap size is restricted. I initially get a JSON file with the URLs to a set of Excel or PDF docs, PUT those to Tika and then PUT those to basex. > > I have had to find a way of chunking (using subsequence) otherwise I get Out of Memory errors. > However, doing a small subsequence seems to take ages. I have had this programme running over 3 days and it didn't complete. Hm, 23k documents does not sound that much. I know too less about Tika. What part of the code is responsible for the error? Could you provide me with the stack trace of the OOM error (you may need to use -d to get it on screen)? Christian

best way to process a collection
by pw＠themail.co.uk 25 Nov '14

25 Nov '14

Hello list I have a large collection of documents that I want to process and was wanting to get peoples' views on the best design patterns for this. I guess I'm looking at how to map-reduce or similar for a FLOWR process, which AFAIK is a single thread operation. Are there any suitable approaches within a single programme? Could I pre-process the programme to define collection subsequences and then run multiple clients against a basex server? TIA Peter

REST queries: "Read permissions needed"
by Jérôme Chauveau 25 Nov '14

25 Nov '14

Hi, i am using BaseX79 as a webapp - embedded in a tomcat7 server. I am working on a php application which runs REST xqueries to my BaseX server. I created a "mydb" database and a user "myuser". Then i granted READ permissions for "myuser". > *GRANT read TO myuser* > *GRAND read TO myuser ON mydb* > *show users* Username Read Write Create Admin ------------------------------------ admin X X X X myuser X > *show users on mydb* Username Read Write --------------------- myuser X All my REST xqueries returns a "READ permission needed." message with the user "myuser" when its works properly with the admin user account. Moreover, REST xqueries via a web browser (logged as 'myuser') works properly too. Did i miss something? Thank's for help.

Same question: http://stackoverflow.com/questions/22676574/why-cant-you-query-database-pat… /rest/xml/path/test.xml returns the content of the XML file, but if you try a query like: /rest/xml/path/test.xml?query=//element you have the error: [BXDB0005] Query must yield database nodes. What's wrong here ? Best regards Florent -- FLOSS Engineer & Lawyer

Dear Chirstian I am opening the database and replacing the existing xml file with new xml file to the database .It is adding successfully,but after that my database size is increasing every replacing operation.Can you please suggest me how to stop the size increment. I am using below code to replacing XML file to database. Context context = new Context(); LocalSession localSess = new LocalSession(context); localSess .execute("OPEN "+"DBANME"); localSess .replace("FILENAME", new FileInputStream("FILEPATH")); Thanks&Regards Chandra Sekhar The information contained in this e-mail and any accompanying documents may contain information that is confidential or otherwise protected from disclosure.

Experiencing unexpected fallback to Xalan with xslt:transform
by Marc van Grootel 23 Nov '14

23 Nov '14

Hi, I was using an XSLT 2 stylesheet to transform xqdoc XML to Markdown. I already had a stylesheet that did the same with HTML. This stylesheet is XSLT 2 and uses Saxon HE which is located inside the BaseX lib directory. Saxon HE is picked up just fine with xslt:transform and xslt:transform-text. I used this as basis for the conversion to markdown. Then I added an xsl:function called i:code-block and suddenly got this error message: [bxerr:BXSL0001] ERROR: 'The first argument to the non-static Java function 'codeBlock' is not a valid object reference.' FATAL ERROR: 'Could not compile stylesheet' Ok, so I changed it to a named template called code-block then I got an error about the string-join used inside. So I re-wrote to not use this xpath function. [bxerr:BXSL0001] ERROR: 'Invalid conversion from 'com.sun.org.apache.xalan.internal.xsltc.dom.AdaptiveResultTreeImpl' to 'node-set'.' So something is causing a fallback to Xalan XSLT 1 processor but I cannot undersand why. However, if I remove all functions and named templates this same stylesheet is compiled and executed fine using Saxon again!!?? If necessary I can add some more code. --Marc
