Out of memory bug
by Ivan Lagunov 31 Jul '13

31 Jul '13

Hello, I've got 'Out of memory' error and corrupted database again, this time it's for 6.3 version. Steps: 1. Started server, started terminal client, checked there are no text and attribute indexes. 2. Started my Java application that runs several tests on database: querying, adding, removing. 3. Then I forgot to reopen terminal client and used the one that I opened in Step 1. 4. Run optimize command for the collection and got error. 5. Cannot open the collection any more as I'm getting 'Out of memory'. It's clear that I shouldn't have used the terminal client that I opened before execution of my Java application. But sometimes it's hard to remember. And it's completely unacceptable that these actions result in the corrupted database. You really should catch ArrayIndexOutOfBoundsException everywhere in order to save database from being corrupted. Terminal client stacktrace: > optimize Possible bug?

Hi, we're observing that our BaseXServer 6.2.7 deadlocks. The stack traces are here: http://top.cs.vt.edu/~gback/bx/deadlock-6.2.7/basex-deadlock.txt Could you take a look to see if these ring any bells? Has this problem been addressed in a more recent version? - Godmar

Hello, I am doing setup for REST enabled basex database with procedure mentioned in http://docs.basex.org/wiki/JAX-RX_API URL. Configuring & starting server and running failed due to class not found, but later I've modified the ./basexrest script as: (Included all the jars in lib folder) ######START #!/bin/bash # Path to this script PWD=`dirname $0` # Paths to distributed files or source directories BASEX=$PWD/BaseX.jar BASEXAPI=$PWD/../lib/basex-api.jar # Classpath LIB=$PWD/../lib LIB_CP="" for JAR_FILE in $LIB/*.jar do LIB_CP="$LIB/$JAR_FILE:$LIB_CP" done CP=$BASEX:$BASEXAPI:$LIB_CP # Options for virtual machine VM=-Xmx1g # Run REST server java -cp "$CP" $VM org.basex.api.jaxrx.JaxRxServer "$@" ######END after this, server started successfully, hit the URL - http://localhost:8984/basex/jax-rx I am getting following exception: java.lang.IncompatibleClassChangeError: Class javax.ws.rs.core.Response$Status does not implement the requested interface javax.ws.rs.core.Response$StatusType at com.sun.jersey.spi.container.ContainerResponse.getStatus(ContainerResponse.java:548) at com.sun.jersey.spi.container.ContainerResponse$CommittingOutputStream.commitWrite(ContainerResponse.java:156) at com.sun.jersey.spi.container.ContainerResponse$CommittingOutputStream.write(ContainerResponse.java:133) at org.basex.io.BufferedOutput.flush(BufferedOutput.java:50) at org.basex.io.PrintOutput.flush(PrintOutput.java:126) at org.basex.data.XMLSerializer.cls(XMLSerializer.java:206) at org.basex.data.Serializer.close(Serializer.java:219) at org.basex.api.jaxrx.BXJaxRx$1.code(BXJaxRx.java:96) at org.basex.api.jaxrx.BXCode.run(BXCode.java:53) at org.basex.api.jaxrx.BXOutput.write(BXOutput.java:53) at com.sun.jersey.core.impl.provider.entity.StreamingOutputProvider.writeTo(StreamingOutputProvider.java:71) at com.sun.jersey.core.impl.provider.entity.StreamingOutputProvider.writeTo(StreamingOutputProvider.java:57) at com.sun.jersey.spi.container.ContainerResponse.write(ContainerResponse.java:299) Your help is appreciated.

help like JAXP in BaseX ?
by Burkert, Michael 25 Jul '11

25 Jul '11

Hello ! We want to fill a JTree with xquery-result, like <A attr="a1"> <B attr="b1"> </B> </A> This returns lines: ResourceSet set = service.query(QUERY); ResourceIterator iter = set.getIterator(); while(iter.hasMoreResources()) { Resource res = iter.nextResource(); System.out.println(res.getContent()); } This returns the XML-structure: DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); factory.setNamespaceAware(true); DocumentBuilder builder = null; Document doc = null; try { builder = factory.newDocumentBuilder(); doc = builder.parse(XMLFile); } catch (xx) NodeList nodeList = doc.getChildNodes(); I need something like NodeList (JAXP), to iterate through xml-structure. How to do this with BaseX ? With best regards Michael
