BaseX steps for Calabash?
by Florent Georges 05 Sep '11

05 Sep '11

Hi, Has anyone ever thought about writing extension steps for Calabash, in order to evaluate queries using BaseX? Using either the standalone processor, or to send queries to the server. Regards, -- Florent Georges http://fgeorges.org/ http://h2oconsulting.be/

SET textindex / attrindex switched around
by Daniël Knippers 29 Aug '11

29 Aug '11

@version 6.7.1 Good evening, Small bug-report: I noticed something odd with the SET command when connected as a client: > set attrindex Full-Text Index: OFF > set textindex Attribute Index: OFF In other words; when I want to change the value of 'attrindex' the reponse mentions the Full-Text Index, whereas trying to change 'textindex' seems to actually change the Attribute Index. -- Daniël

XML name characters and regexes with multi-character escapes?
by C. M. Sperberg-McQueen 25 Aug '11

25 Aug '11

Recently I had occasion to test a string to see whether it is an NCName. I typed something like: matches("foo","\i\c*") But instead of the value 'true', I got an error message saying that '\i\c*' is an invalid regular expression. I believe it is a valid regular expression and that \i and \c are defined as multi-character escapes in XSD. Other multi-character escapes (., \s, ...) seem to be supported. Am I missing something? Since \i and \c vary for different versions of XML, perhaps BaseX is expecting me to tell it which version of XML I want to be using for them? I'm currently using 6.5.1 and have not checked against the current version of BaseX, but I don't see anything about regular expressions in the change logs. -- **************************************************************** * C.

XQuery / BaseX: distinct after sort
by Mainberger, Christof 24 Aug '11

24 Aug '11

Hi, I got some performance problems with basex: My query is distinct-values(for $item in doc('gemaelde')/items/item order by $item/kuenstler/@order return $item/kuenstler). It takes about 26 s for 1.500 items. Is there any possibility to formulate the query in other ways to make this faster? Or indexes/materialized views to support such kind of queries? This problem occurs only on our Debian (virtual) server, not on my PC. Are there any configuration parameters for basex-server (ram etc.), which might help? Thanks!

Embedded BaseX server restart
by Igor Farinic 23 Aug '11

23 Aug '11

Hi, we have problem with restart (stop and immediate start) of embedded BaseX server. The root cause is that when you close server socket it remains in a timeout state for a period of time and restart fails, because it is not possible to bind to a socket in timeout state. Enabling SO_REUSEADDR prior to binding the socket using bind allows the socket to be bound even though a previous connection is in a timeout state. Following fix in BaseXServer class should help (lines 94 and 95): socket = new ServerSocket(); socket.setReuseAddress(true); SocketAddress endpoint = new InetSocketAddress(port); socket.bind(endpoint); esocket = new ServerSocket(); esocket.setReuseAddress(true); endpoint = new InetSocketAddress(context.mprop.num(MainProp.EVENTPORT)); esocket.bind(endpoint); regards, Igor Farinic

vanishing namespace declaration
by Igor Farinic 16 Aug '11

16 Aug '11

Hi, in BaseX 6.7.2 beta we are hitting new issue, that we haven't observed in 6.7.1. I store following xml: <task oid="91919191-76e0-59e2-86d6-998877665544" xmlns="http://midpoint.evolveum.com/xml/ns/public/common/common-1.xsd" xmlns:c="http://midpoint.evolveum.com/xml/ns/public/common/common-1.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:my="http://myself.me/schemas/whatever"> <extension> <my:shipState>capsized</my:shipState> <my:dead xsi:type="xsd:integer">42</my:dead> </extension> </task> ... and when I retrieve it, the xsd namespace declaration is missing. However the xsd namespace is used in value of xsi:type attribute. regards, Igor Farinic

Hello everybody, I created some BaseX REST client examples with C# and Scala. Feedback is welcome since I am not a professional Scala and C# developer ;) The Java BaseX REST client examples can be found here [1]. regards Lukas [1] http://docs.basex.org/wiki/JAX-RX_API#Usage_Examples

Re: [basex-talk] BaseXServer.bat not respecting the -c"SET DBPATH ..." option?
by Igor Farinic 15 Aug '11

15 Aug '11

Hi, I am hitting the same issue: When I pass set dbpath command on server start, it seems that the server sets the new value, but is partially ignoring it. Logs are created in new directory, however data are stored in default directory (~/BaseXData/). It is causing problems, because I cannot run 2 BaseXServer instances over the same directory. How to replicate: String serverPath = "SOME_PATH"; StringBuffer commands = new StringBuffer(); commands.append("-cset dbpath ").append(serverPath).append(";info"); new BaseXServer("-d", "-D", "-s", commands.toString()); Environment: BaseX 6.7.1 regards, Igor Farinic

Embedded BaseX server exits whole process
by Igor Farinic 15 Aug '11

15 Aug '11

Hi, in our junit tests we are starting BaseX server in embedded mode. The problem is that, if there is some problem (e.g. server socket is unable to bind to port), basex server will terminate whole process. When the process is terminated during automatic junit test execution, then maven surefire plugin will report that 0 test were executed and all passed ... and we will never know that there are some problems in our application code :( I am using following command to initialize BaseX server: server = new BaseXServer("-p" + port, "-d", "-D", "-s"); Environment: BaseX 6.7.1 regards, Igor Farinic

BaseX: Support for JSON
by Christian Grün 14 Aug '11

14 Aug '11

Dear all, we've just added a frequently requested feature to the latest snapshot of BaseX: JSON files can now be converted to XML and back to their original representation! The chosen XML representation is supposed to be well readable and easily editable. As there is no lossless, bidirectional conversion available for XML and JSON, we have also added support for the JsonML format, which allows to serialize arbitrary XML documents to JSON and back to XML. More information is found in our Wiki [1]. Feel free to check out our latest sources [2] and snapshots [3], and don't hesitate to give us your valuable feedback. All the best, Christian [1] http://docs.basex.org/wiki/JSON [2] https://github.com/BaseXdb/basex/ [3] http://files.basex.org/releases/latest/ ___________________________ BaseX Team Christian Grün Uni KN, Box 188 D-78457 Konstanz http://www.basex.org
