Fwd: Incorrect implementation of XQUF?
by software developer 23 May '11

23 May '11

Hi, All I did was upgrade from 6.5.1 to 6.6.3-SNAPSHOT which I took from BaseX file-server today (a couple of hours ago) and I get: Not expected (Data Access out of bounds [pre:2050100, indexSize:8028, access:8028 > 8027] This is quite similar to the issue I faced when I raised the original query regarding XQUF (this thread). Immediately downgraded to 6.5.1 and the issue got fixed (I did not update the data at all). Thanks.

(Poss.) Bug Report BaseX 6.6.2
by Loyde Yates 22 May '11

22 May '11

Dear BaseX, Don't know if this is important. I'm new to BaseX, but I thought I should relay the entry I received when attempting to download info into BaseX. The six previsous files seem to load okay. I still have to learn more to make that determination. Thanks for making the software available! Loyde Yates Error: Possible bug?

JAXRXPATH property, Basic auth
by Computer Software Developer 20 May '11

20 May '11

1. After upgrading to 6.6.2 from 6.5.1, JAXRX cannot find my xquery files stored on server side even though the property JAXRXPATH is defined and is pointing to the directory containing the xquery files, the directory is mounted. Any pointers on how it should be configured? Below is the ~/.basex file's contents: DBPATH = /home/developer/BaseXData JAXRXPATH = /media/queries/ LANG = English LANGKEYS = false HOST = localhost PORT = 1984 SERVERPORT = 1984 JAXRXPORT = 8984 TIMEOUT = 0 Do I need to specify RESTPATH instead (if I do that, I get RESTPATH not found message upon JAXRX server startup)? 2. I have been trying to provide basic auth using admin:admin@localhost:8984 notation in the URL in Firefox, but Firefox says the web-site does not require authentication and then does not apparently pass the auth header to JAX-RX. Does JAX-RX not return 401 with WWW-Authenticate header so the user can authenticate? Thanks.

Determine remote server version.
by Huib Verwey 20 May '11

20 May '11

Hi all, I'm trying to determine the BaseX version running a remote server. When I connect using the client on my local machine the server does not say which version it is When I use the GUI to connect to the remote server I can't find any info on the version. When I login to the remote machine and go to the server folder I can't find any info on which version it is. When I look at the logs in the .logs folder I can't find any info on the server version (I could not find the startup info that the server generates). I copied the BaseX.jar to a place where I could unpack it and found version "6.6" in the META-INF/maven/org.basex/basex/pom.xml file. Is there a more convenient way of determining the remote version that I missed? And did I actually find the correct version in the pom? Hartelijke groet, Huib Verweij. P.S. In the BaseX GUI the "Logs" tab shows me the logs of the local BaseX even when I connect to a remote BaseX - could be on puprpose, I just found it somewhat counter intuitive.

Re: [basex-talk] Renaming of documents
by Leo Wörteler 18 May '11

18 May '11

Hi Thomas, I could reproduce the bug and we'll fix it soon. Your query however looks a bit strange to me: Am 21.04.2011 14:31, schrieb Thomas Kaltofen: > insert node collection('db/docb')/rootB > after collection('db/doca')/rootA Your collection looks something like this: > collection(db) > | > |-- document(doca) > | | > | `-- <rootA .../> > | > `-- document(docb) > | > `-- <rootB .../> Your query doesn't create a new document node (as XQuery Update doesn't operate on document level) but inserts the <rootB .../> element directly into the first document, which then has two(!) root elements: > collection(db) > | > |-- document(doca) > | | > | |-- <rootA .../> > | | > | `-- <rootB .../> > [...] That's allowed in XQuery Update, but isn't valid XML any more and I can't think of a scenario where it's actually desirable. Is that what you wanted to do? If not, could you explain in more detail what you intended? Cheers Leo

Re: [basex-talk] BaseXServer.bat not respecting the -c"SET DBPATH ..." option?
by Jason Klassen 17 May '11

17 May '11

Hi Christian, Using 6.6.3 does solve the default directory creation but it still does not respect the SET DBPATH for execution. What I also noticed was that after I start the basexserver I can change the .basex file on the fly and the clientsession in the app will then reflect that change. So something still seems to give the .basex dbpath value precedence. Interestingly the logs are recording and locked using the directory from -c"SET DBPATH..." even when I change the .basex file. Here's the command I was using to start it up. Makes no difference if I replace basex-6.6.3-SNAPSHOT.jar in the basexserver.bat either. C:\BaseX\bin>java -cp C:\basex\basex-6.6.3-SNAPSHOT.jar org.basex.BaseXServer -p1985 -c"SET DBPATH C:/BaseX/BaseXData;info" General Information Database Path: C:/BaseX/BaseXData Used Main Memory: 1129 KB Database Creation Whitespace Chopping: ON Entity Parsing: OFF Indexes Path Summary: ON Text Index: ON Attribute Index: ON Full-Text Index: OFF BaseX 6.6.3 beta [Server] Server was started. Jason -----Original Message----- From: Christian Grün [mailto:christian.gruen@uni-konstanz.de] Sent: May-17-11 3:54 AM To: Jennifer Violago; Jason Klassen Subject: Re: [basex-talk] BaseXServer.bat not respecting the -c"SET DBPATH ..." option? Dear Jason, I had a quick look into the code base; the commands (specified by -c) were executed after having initialized the server instance. As a consequence, the default database directory was created before parsing the DBPATH option. I decided to switch the execution order: the specified commands will now be executed before initializing the logger (which is responsible for creating the database/.logs directory, and locking that folder). Feel free to give us some feedback on the latest 6.6.3 snapshot of BaseX (which is as stable as the official release): http://files.basex.org/releases/latest/ Hope this helps, Christian
