basex SERVERHOST
by Liam R E Quin 22 Dec '12

22 Dec '12

How do I use SERVERHOST in ~/.basex (or elsewhere) to get basex to listen on the given PORT only on localhost (127.0.0.1) and not on externally-visible IP addresses? Setting SERVERHOST and HOST to localhost does not seem to accomplish this.

server / GUI synchronization and data safety
by C. M. Sperberg-McQueen 22 Dec '12

22 Dec '12

At various points in the documentation, it is observed that the BaseX server, the BaseX client, and the GUI interface all run in different virtual machines, so the GUI and the server's databases are not synchronized. In the GUI of BaseX 7.3, I see an optional Server Administration on the Database menu, which carries the warning Warning: The client/server architecture and the GUI are not synchronized. The same database should not be opened from clients and the GUI. Does this mean that it's safe to run both the server and the GUI as long as they have different databases open? (It doesn't say that; it says it's unsafe if they have the *same* database open. You see how timid warnings can make a user!) Also - in my case it would be convenient to be able to open the GUI and do some work while the BaseX HTTP server is running. If the HTTP server handles a request directed at database X, does that database remain open indefinitely or is it closed when the request has been handled? That is, is it safe to work with database X as long as I don't pass requests against X to the HTTP server at the same time/ And third - if neither the HTTP server nor the GUI are performing any updates, but only retrievals from the database, does the warning still apply, or is read-only access from multiple instances of BaseX actually safe? (I ask because if I need to shut down the HTTP server every time I want to launch the GUI to experiment with a new function, and then shut down the GUI so I can launch the HTTP server and work on the Web interface to the new function, then I am going to want to find a more convenient way of starting and stopping the HTTP server than going into a terminal window and running the shell script.)

Spatial XQuery
by David Stuebe 21 Dec '12

21 Dec '12

Hi Basex-ers I am new to the list but have been working with basex for a few weeks now. We are using basex to search ISO 19115 geospatial metadata. The full text search is simple and works better than any of the existing purpose built catalog tools we have worked with so far. I am very interested in the pervious thread on Spatial Xquery. https://mailman.uni-konstanz.de/pipermail/basex-talk/2012-January/002484.ht… I am looking over the Geo Module geospatial API<http://expath.org/spec/geo> today, and also at Zorba's Geo Module<http://www.zorba-xquery.com/html/modules/expath/geo> implementation. Has the Basex community made an further progress? The API is the first issue and so far the Geo Module definition looks great. If linear search using the existing attribute indexes is all that is available now, that is fine. It would be fantastic to write a geo spatial index to support that API in basex in the future. What type of indexes have you considered? I would think an Rtree would probably be best for supporting that API. This email is essentially a status query – as I work on this over the next week or two we can start new threads for specific topics.

Restxq updating functions running indefinitely.
by France Baril 19 Dec '12

19 Dec '12

Hi, I just upgraded to 7.5 from 7.4. Everything seems to work except the Updating functions db:replace and db:store (I use db:add elsewhere and it works as it did before). There is very little information regarding what the problem could be: - I am starting the httpserver with these .basex settings: USER = admin and PASS = admin. So I do not expect the problem to be security. - Symtom: the query runs and never times out. Browser stays on empty page. I have to stop the server with the httpstop script. - Error messages in the terminal window: None. - When I start the server I get this message before the server starts: Null identity service, trying login service: null Finding identity service: null I tried two different 7.5 snapshots including today's RC1. Any clue is welcome. -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com (514) 572-0341

DTD validation
by France Baril 18 Dec '12

18 Dec '12

Hi, We are having challenges with validation. We have built a Documentation Controller for authors that create XML content. On a regular basis, we ask them to check that all documents are valid. We are running the process on hundreds of file. the ideal situation would be to collect all errors and display them of the webpage for authors to find and correct. Ex. of dream code: *let **$db* := *app:open-db*(*$lang*) *let* *$topic-validation* := <ul>{*for **$x* *in **$db*/*[* name*()='topic' or *name*()='media'] *return if* (*contains*(* validate:dtd*(*$x*, *$app:dtd-topic*), 'BXVA0001')) *then *<li>File {*$x*/* base-uri*()} doesn't validate against the DTD.</li> *else *() } </ul> *let* *$menu-validation* := <ul>{*for **$x* *in **$db*/*[* name*()='menu'] *return if* (*contains*(* validate:dtd*(*$x*, *$app:dtd-menu*), 'BXVA0001')) *then *<li>File {*$x*/* base-uri*()} doesn't validate against the DTD.</li> *else *() }</ul> *return if* (*count*(*$topic-validation*/*li*) + *count*(* $menu-validation*/*li*[*normalize-space*(.) != '']) != 0) *then *<div>{*$topic-validation*}{*$menu-validation*} </div> *else *<ul><li *style*=*"color:green"*>All menus and topics validate against the DTDs.</li></ul> Instead, as soon as validate:dtd finds one single file with an error, it crashes the web page with an error message like this: Stopped at line 270, column 77 in /Applications/basex75/webapp/restxq/How2_Admin.xqm: [BXVA0001] Validation failed: 1355790115420.xml, 3:22: Element type "headin" must be declared. On top of this, the name of the file that is referenced in the error message doesn't exist. I've been querying the DB to find errors. Ex. Search for all files with 'headin' in this case. However, we'd really like the writer to be able to find their own faulty files. Are we misusing the function? Is this a bug? What can we do about it? Thanks in advance for you help! -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com (514) 572-0341

Binding a sequence to an external variable?
by Johannes Krampf 18 Dec '12

18 Dec '12

Hello, I would like to bind a sequence of xs:string to an external variable. I've tried various ways and after trying to read the source and the spec I fear that it might not be possible. First of all the code: Inside the xquery: declare variable $mysequence as xs:string* external; On the Java side: ClientQuery clientQuery = clientSession.query(query); clientQuery.bind(parameter, values.get(parameter)); I tried to give the type "xs:string*" as a third parameter to clientQuery.bind, but I got the error message "org.basex.core.BaseXException: [XPST0003] Unknown type 'xs:string*'", so this is not the way to do it. I furthermore tried to pass a string array as a parameter, but the variable got the value of the output of the toString method. When I tried with a list of Strings, I got again the output of the toString method. What I want is something like the following: let $mysequence := ("Hello", "world") but using sequence values transmitted from the java application using an external variable. Is there any way to achieve this? The goal is to test for membership in the sequence, i.e. allowing the parametrize the query using a variable number of possible values. Thanks for your assistance, Johannes

Full Text Index giving error for ..7.5 GB XML Data
by John Best 18 Dec '12

18 Dec '12

Dear XML Team, I have a XML DB of size 7.5GB. When creating an Full-Text Index I get an error message - * Out of Main Memory. You can try to: - increase Java's heap size with the flag -Xmx<size> - deactivate the text and attribute indexes.* I tried this with 7.3 and thru GUI... To make searching fast I need FT Index.. :( Another interesting thing I would like to highlight about this error.... In the data folder the FT Index files (ftxXX and ftyXX is the format of the files) are created... The first time when this happened, I checked the data folder and found that the above ftxXX and ftyXX files where up to ftx23 and fty23. Then I tried Full-Text index again with no success. Again I checked the same files. This time they were up to ftx36 and fty36... This might help you that is why I am mentioning..... -- Have a nice day JBest
