Command history in basex client
by adj7388 12 Aug '15

12 Aug '15

Hello, Does the basex command line client keep no command history? I am using the Linux version. In most Linux command line programs, the up- and down-arrows allow you to scroll through past commands so you don't have to retype them every time. I see "Save command-line history" in the change log for version 8.0.1 ( and I have version 8.2.3 installed) but command history does not appear to work. Thanks, Alan

HTML parsing in the DBA
by Kristian Kankainen 12 Aug '15

12 Aug '15

Hello! I tried simple cut and paste from the wiki and came up with the following query for importing an HTML file. The DBA says "Query was successful", but no resources are never added to the db. declare option db:parser "html"; declare option db:htmlparser "html=false,nodefaults=true"; db:replace("dbname", "filename.html", "/file/path/filename.html") I'm running the latest war file on Tomcat. Best wishes Kristian Kankainen

Using BaseX With oXygenXML: Validate XQuery 3.1 Syntax
by Eliot Kimber 09 Aug '15

09 Aug '15

I've started using oXygenXML rather than the DBA Web app to run my test queries (mostly so I can handle large result sets in the output). If I have a statement like: Let $foo as map(*) := map {} Oxygen reports a static validation error. If I remove the "as" clause, then it's happy. My question: is it possible to configure oXygenXML so it validates the 3.1 expressions BaseX supports? I'm not sure if this an oXygenXML or a BaseX issue. Thanks, Eliot ---- Eliot Kimber, Owner Contrext, LLC http://contrext.com

Scope of options set with SET
by Amanda Galtman 06 Aug '15

06 Aug '15

Hi, I'm not sure if the following is a bug or if I misunderstand the scope of options set with SET. Suppose I have a) A DTD that defines a text entity b) A catalog file that points to the DTD c) An XML file with a DOCTYPE line that references the DTD, and XML content that references the text entity If I do the following in a standalone BaseX session SET DTD true SET CATFILE [path to my catalog file...] xquery fetch:xml([path to my XML file...]) then the text entities are missing, presumably because the catalog or DTD is not being read. Either of the following works as expected, with the text entities resolved: xquery fetch:xml([path to my XML file...],map {'dtd': true(), 'catfile': [path to my catalog file...]}) xquery doc([path to my XML file...]) But why do I have to use the 2nd input in fetch:xml if I used SET in the same session? I thought the SET command would suffice, and the 2nd input argument in fetch:xml was available if I either wanted to override an option I had previously set with SET or did not use SET previously. Thanks, Amanda

SIGPIPE error
by mar＠centrum.cz 06 Aug '15

06 Aug '15

Hi, I am having difficulties with populating BASEX database. I have plenty of XML files (~ half a million, with various sizes ranging from several kilobytes up to hundred of kilobytes). I use BASEX Java API and finally I call for each file org.basex.core.cmd.Add. I am trying to import them into BASEX database, in fact there are 22 types of files (22 XSD definitions) the files conform to, so I have 22 different databases in a single BASEX server. I have plenty of RAM and CPU power and I monitor the process (both -- the BASEX server and my client program) from within JVisualVM, the JVM reaches the CPU boundaries, but RAM is never exhausted. Before importing, I need to enhance the XML data with some additional information taken from SQL database. I have written a Groovy multithreaded program that uses BASEX Java API with heavy use of GPars library. Simply put, the program: 1. has several producer threads -- each producer reads given portion of the database and provides those additional information 2. has several consumer threads -- each consumer takes the original files, wraps it with additional information and finally calls org.basex.core.cmd.Add command. Various testing with less data (upto ~ several thousands of files) provides good results -- no loss of data, BASEX server and my client program behaves as it should. Unfortunately when trying to import all of the files, the program starts fine, but when it gets "warm" I got SIGPIPE errors in log from time to time (as I said, there is plenty of RAM and CPU available) (see attachment please). Comments to picture: 1. I am adding document with ID ISPOP_166007 -- this ID is indeed missing in the final database 2. just simple call to Add: Closure add = { session -> def cmd = new org.basex.core.cmd.Add(dsn, enhancedXml) session.execute(cmd) } 3. I am reusing the session, the session is bound to current thread and never gets closed until the thread (consumer) finishes There is nothing wrong in BASEX server log, other documents are added just fine, there is no trace about document ISPOP_166007. Just for reference the complete stack trace follows: - - - - ERROR basex.support.AddResourcesSupport - unable to consume ISPOP_166007 java.net.SocketException: Roura přerušena (SIGPIPE) at java.net.SocketOutputStream.socketWrite0(Native Method) ~[na:1.8.0_45] at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:109) ~[na:1.8.0_45] at java.net.SocketOutputStream.write(SocketOutputStream.java:153) ~[na:1.8.0_45] at org.basex.io.out.BufferOutput.flush(BufferOutput.java:60) ~[basex-8.2.jar!/:8.2] at org.basex.io.out.BufferOutput.write(BufferOutput.java:54) ~[basex-8.2.jar!/:8.2] at org.basex.io.out.PrintOutput.write(PrintOutput.java:66) ~[basex-8.2.jar!/:8.2] at java.io.OutputStream.write(OutputStream.java:116) ~[na:1.8.0_45] at java.io.OutputStream.write(OutputStream.java:75) ~[na:1.8.0_45] at org.basex.api.client.ClientSession.send(ClientSession.java:238) ~[basex-8.2.jar!/:8.2] at org.basex.api.client.ClientSession.execute(ClientSession.java:160) ~[basex-8.2.jar!/:8.2] at org.basex.api.client.ClientSession.execute(ClientSession.java:167) ~[basex-8.2.jar!/:8.2] at org.basex.api.client.Session.execute(Session.java:36) ~[basex-8.2.jar!/:8.2] at org.basex.api.client.Session$execute.call(Unknown Source) ~[na:na] at basex.support.AddResourcesSupport$_consume_closure9$_closure17.doCall(AddResourcesSupport.groovy:255) ~[basex-1.0.jar!/:na] at sun.reflect.GeneratedMethodAccessor368.invoke(Unknown Source) ~[na:na] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[na:1.8.0_45] at java.lang.reflect.Method.invoke(Method.java:497) ~[na:1.8.0_45] at org.codehaus.groovy.reflection.CachedMethod.invoke(CachedMethod.java:93) [groovy-2.4.4.jar!/:2.4.4] at groovy.lang.MetaMethod.doMethodInvoke(MetaMethod.java:325) [groovy-2.4.4.jar!/:2.4.4] at org.codehaus.groovy.runtime.metaclass.ClosureMetaClass.invokeMethod(ClosureMetaClass.java:294) [groovy-2.4.4.jar!/:2.4.4] at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:1019) [groovy-2.4.4.jar!/:2.4.4] at org.codehaus.groovy.runtime.callsite.PogoMetaClassSite.call(PogoMetaClassSite.java:42) [groovy-2.4.4.jar!/:2.4.4] at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:125) [groovy-2.4.4.jar!/:2.4.4] at basex.BasexSessionRegistry.withThreadBoundSession(BasexSessionRegistry.groovy:79) ~[basex-1.0.jar!/:na] at basex.BasexSessionRegistry$withThreadBoundSession$0.call(Unknown Source) ~[na:na] at basex.support.AddResourcesSupport$_consume_closure9.doCall(AddResourcesSupport.groovy:257) ~[basex-1.0.jar!/:na] at sun.reflect.GeneratedMethodAccessor327.invoke(Unknown Source) ~[na:na] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[na:1.8.0_45] at java.lang.reflect.Method.invoke(Method.java:497) ~[na:1.8.0_45] at org.codehaus.groovy.reflection.CachedMethod.invoke(CachedMethod.java:93) [groovy-2.4.4.jar!/:2.4.4] at groovy.lang.MetaMethod.doMethodInvoke(MetaMethod.java:325) [groovy-2.4.4.jar!/:2.4.4] at org.codehaus.groovy.runtime.metaclass.ClosureMetaClass.invokeMethod(ClosureMetaClass.java:294) [groovy-2.4.4.jar!/:2.4.4] at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:1019) [groovy-2.4.4.jar!/:2.4.4] at org.codehaus.groovy.runtime.callsite.PogoMetaClassSite.call(PogoMetaClassSite.java:42) [groovy-2.4.4.jar!/:2.4.4] at org.codehaus.groovy.runtime.callsite.BooleanReturningMethodInvoker.invoke(BooleanReturningMethodInvoker.java:51) ~[groovy-2.4.4.jar!/:2.4.4] at org.codehaus.groovy.runtime.callsite.BooleanClosureWrapper.call(BooleanClosureWrapper.java:53) ~[groovy-2.4.4.jar!/:2.4.4] at org.codehaus.groovy.runtime.DefaultGroovyMethods.find(DefaultGroovyMethods.java:3908) ~[groovy-2.4.4.jar!/:2.4.4] at org.codehaus.groovy.runtime.dgm$191.invoke(Unknown Source) ~[groovy-2.4.4.jar!/:2.4.4] at org.codehaus.groovy.runtime.callsite.PojoMetaMethodSite$PojoMetaMethodSiteNoUnwrapNoCoerce.invoke(PojoMetaMethodSite.java:274) ~[groovy-2.4.4.jar!/:2.4.4] at org.codehaus.groovy.runtime.callsite.PojoMetaMethodSite.call(PojoMetaMethodSite.java:56) ~[groovy-2.4.4.jar!/:2.4.4] at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:125) [groovy-2.4.4.jar!/:2.4.4] at basex.support.AddResourcesSupport.consume(AddResourcesSupport.groovy:251) ~[basex-1.0.jar!/:na] - - - - Best Regards, Martin

Running BaseX In A Docker Container?
by Eliot Kimber 05 Aug '15

05 Aug '15

As part of my DITA For Small Teams project we're setting up a set of coordinated Docker containers to manage the various components (git server, Jenkins server, BaseX server). We're setting up our own custom containers so that they are appropriately pre-configured. In the case of BaseX that means configured with the DFST Web app and supporting modules, configuration details, etc. Just curious if anyone has experience putting BaseX in a container and if there's anything we should look out for or anything we can contribute back out of this effort. Cheers, E. ---- Eliot Kimber, Owner Contrext, LLC http://contrext.com

Destination of result-document from XSLT module
by Lizzi, Vincent 05 Aug '15

05 Aug '15

I'm trying to use the XSLT Module in BaseX 8.2.3 with Saxon 9.6 to run an XSLT that produces several output documents using xsl:result-document. I'm having trouble setting the location of the output documents. I want to have xsl:result-document create the output documents in a temporary folder because the documents need to be zipped together. According to Saxon's documentation, the a relative path in the href attribute of xsl:result-document will be resolved using either the path of the Destination, or the current directory. The XSLT Module does not appear have a way to provide a path for a destination document. What I'm seeing is that the result documents are created in BaseX's home directory. The XSLT works as expected when run using Saxon from the command line, where it's possible to set a destination path. Is there a way to specify a Base Output URI to the XSLT Module? Or, would it be possible to specify a file URI output location to a method like xslt:transform? One possible workaround is to provide an absolute path as a parameter to the XSLT, and use that parameter in the xsl:result-document href location. Here is a self-contained example code: declare function local:example($in, $xsl, $zipPath) { let $tempDir := file:create-temp-dir('test', 'example') let $x := xslt:transform-text($in, $xsl) return let $zip := archive:create-from($tempDir) return ( file:write-binary($zipPath, $zip) (: , file:delete($tempDir, true()) :) ) }; let $xsl := <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" version="2.0"> <xsl:template match="/"> <xsl:result-document href="doc1.xml"> <test>this is a test 1 <xsl:apply-templates/></test> </xsl:result-document> <xsl:result-document href="doc2.xml"> <test>this is a test 2 <xsl:apply-templates/></test> </xsl:result-document> </xsl:template> </xsl:stylesheet> let $doc := <test>this is input</test> let $zipPath := 'report.zip' return local:example($doc, $xsl, $zipPath) The expected output is a zip file report.zip that contains doc1.xml and doc2.xml. However, what I'm seeing is that report.zip is created as an empty zip file and doc1.xml and doc2.xml are placed in BaseX's home directory. Thanks, Vincent
