Question re starting basexhttp
by spaelti 12 Oct '14

12 Oct '14

I have been trying to run BaseX as a web application on my mac. After some difficulties I have gotten it to work. However there is one thing that I am still unsure about. Whenever I start the web server using ‘basexhttp’ I get the following message: /usr/local/bin/basexhttp: line 11: cd: /usr/local/Cellar/basex/7.9/libexec/../basex: No such file or directory However everything thereafter seems to work fine. So why do I get this message, or what does it mean? In my installation (which I got through the brew script) there is no ‘basex’ file/folder at the specified location (which would be in the ‘7.9’ folder). Should there be? Any help or advice would be much appreciated. best Philip This is what /usr/local/Cellar/basex looks like: ---- basex 7.9 bin changelog.txt INSTALL_RECEIPT.json libexec BaseX.jar bin lib webapp license.txt readme.txt ---- --------------------------------------------------- Philip Spaelti Kobe Shoin Women's University, Graduate school ---------------------------------------------------

zsh plugin
by Dirk Kirsten 12 Oct '14

12 Oct '14

Hello, if any of you uses the excellent zshell, you might be interested in this small plugin for BaseX for the zsh: https://github.com/dirkk/zsh-basex. Aliases might also be useful for every other shell user, because they basically shorten all basex commands (e.g. bx is defined as an alias for basex).

BaseX Cluster Solution based on Galera Cluster
by Jaco van der Merwe 09 Oct '14

09 Oct '14

Hi All, We have recently started using the Galera Cluster for MySQL which works really well as either a single or a multi-master cluster with semi-synchronous replication. See http://galeracluster.com/ for more information. The nice thing about the Galera Cluster is that the cluster and replication management functionality has been abstracted and extracted into a component (actually an .so file) called the WSREP provider. The latter provides hooks that can be integrated into your DB. I was thinking that this could be a very nice solution for providing a cluster solution for BaseX. So my question is whether anybody out there has done this already for BaseX, or may have plans for doing this. Thanks Jaco

confused
by Rob Stapper 08 Oct '14

Hi, I'm confused. The code below results in false() for $e1 and true() for $e2. Shouldn't both be false? I must be overlooking something. Can somebody enlighten me, please? let $node := <node ID="X"><node ID="Y"/></node> let $e1 := exists( trace( $node/node[ ./@ID = "Z"], 'node: ')) let $e2 := exists( $node/node[ ./@ID = "Z"] ) return ( $e1, $e2) Thnx in advance, Rob Stapper --- Dit e-mailbericht bevat geen virussen en malware omdat avast!

regex for xquery
by Rob Stapper 08 Oct '14

08 Oct '14

Hi, Basically I want to break down the path-expression of a node in my XML into its elementary steps. QName: "Q{http://www.w3.org/2005/xpath-functions}root()/Q{}A[1]/Q{}B[1]/Q{}C[1]/Q{} D[1]" must become QName-sequence: ("Q{http://www.w3.org/2005/xpath-functions}root()", "Q{}A[1] ", "Q{}B[1] ", "Q{}C[1] ", "Q{}D[1]") So I need to break the path-expression down on the "/"-characters which aren't part of the namespace-uries. I'm using the "fn:tokenize"-function for this. The function uses a "regular expression" for it's separator. Unfortunately my regex-experience is zero (well, two days by now). I came up with the next brilliant ;-) solution: fn:tokenize( path( $node), "/(?=Q)"). Again, unfortunately, this doesn't work because the xquery-flavor of regex doesn't support looking around. Sure, I can use "/Q" as pattern and subsequently stick a "Q" in front of every substring (except the first one) but I'm looking for a solid solution. I there anyone out there with enough "regex-for-xquery"- experience to help me with this? Big thanx for that in advance. @Christian: On the other hand I can imagine that within Basex the path-expression is built from these elementary steps. If so, is it in any way possibly to retrieve this elementary steps sequence instead of this path-expression? Thanx, Rob Stapper --- Dit e-mailbericht bevat geen virussen en malware omdat avast!

IllegalMonitorStateException
by Gerald de Jong 07 Oct '14

07 Oct '14

Dear BaseX experts, I'm wondering if anybody can see something that I'm doing wrong. I would expect it to be possible to add documents from multiple threads. Am I wrong about that?? When I set two of my datasets saving documents to BaseX 7.9 at the same time, I get this exception: $ basexserver BaseX 7.9 [Server] Server was started (port: 1984) Exception in thread "Thread-2295" java.lang.IllegalMonitorStateException at java.util.concurrent.locks.ReentrantReadWriteLock$Sync.tryRelease(ReentrantReadWriteLock.java:374) at java.util.concurrent.locks.AbstractQueuedSynchronizer.release(AbstractQueuedSynchronizer.java:1260) at java.util.concurrent.locks.ReentrantReadWriteLock$WriteLock.unlock(ReentrantReadWriteLock.java:1131) at org.basex.core.DBLocking.release(DBLocking.java:219) at org.basex.core.Context.unregister(Context.java:249) at org.basex.core.Command.execute(Command.java:104) at org.basex.core.Command.execute(Command.java:117) at org.basex.server.ClientListener.execute(ClientListener.java:384) at org.basex.server.ClientListener.add(ClientListener.java:355) at org.basex.server.ClientListener.run(ClientListener.java:100) All I am doing is making concurrent calls in two parallel sessions: session = new ClientSession(...) session.execute(new Open(database)) session.execute(new Set("autoflush", "false")) session.add([path string], [document-bytes]) // a zillion times session.execute(new Flush()) During the execution of the parallel add commands, it crashes.

Re: [basex-talk] $ = AltGr + É
by Dániel Kiss-Kálmán 06 Oct '14

I think I found somehing but need help to correct it. CTRL Home is the jump to top shortkey. I went to http://www.w3.org/2002/09/tests/keys.html to check CTRL Home = keycode 36, but no charcode AltGR É = keycode 0, charcode 36 (and CTRL and ALT is pressed because of AltGR. so AltGr is nothong more than CTRL + ALT). basex / basex-core / src / main / java / org / basex / gui / layout / BaseXKeys.java line 31: /** Beginning of text. */ TEXTSTART(META, MAC ? VK_UP : VK_HOME), Can oneone please tell me how to correct it if I'm on the right way? maybe check the ALT or any other way? Daniel

Eclipse vs BaseX Gui differences ?
by jean-marc Mercier 06 Oct '14

06 Oct '14

Hi all, Happy to write again in this mailing-list, hope you are all doing well guys ! I am encountering a small problem running my old xquery modules. I guess that it is a classical issue, but I can't remember how to look into BaseX archive :( Here is the description of the problem : I am running a query, calling module_of_mine.xqm, on two different environments. The first one is eclipse, linked to the latest interpreter from BaseX80-20140923.183154 (but I tested also against older interpreter). In this way, this query saturated my 12 G Java machine after some minutes. Then I installed module_of_mine.xqm into BaseX repo, and ran the same query using basex gui with 4G heap size. The query ran perfectly in some 30 sec. My first penny guess is that the built-in BaseX xquery profiler is doing some nice work there ? If so, is there a way to activate / desactivate this profiler from eclipse or from some configuration files ? Cheers, Jean-Marc

$ = AltGr + É
by Dániel Kiss-Kálmán 06 Oct '14

06 Oct '14

Hello Basex-Talkers, when I try to enter a variable I need the $ char. I use hungarian keyboard, and $ is AltGr + É keyboard combination. The only annoying thing is when I press AltGr + É, $ appears, but just before that cursor jumps to the first row first char position. So $ is smiling as the first char in the first row. No other keboard combination does that, only AltGr + É. So every time I need a variable I use clipboard instead of pressing $ char. Can onyone make my life a little easier to correct it if it is possible at all? Or help me how to try to remove that cursor jump? Thanks in advance, Daniel
