Server Crash
by Sony Vijay 26 Feb '11

26 Feb '11

Hi, I am using BaseX 6.5. I am running into a server crash. Could you fix it ? I see the following error where I run my server: Exception in thread "Thread-4" java.lang.NullPointerException at org.basex.query.up.Updates.size(Updates.java:110) at org.basex.query.QueryProcessor.updates(QueryProcessor.java:234) at org.basex.server.QueryProcess.initInfo(QueryProcess.java:162) at org.basex.server.QueryProcess.close(QueryProcess.java:139) at org.basex.server.ServerProcess.query(ServerProcess.java:291) at org.basex.server.ServerProcess.run(ServerProcess.java:128) Also, please find attached a copy of the complete log file. Thanks, Sony

Re: [basex-talk] BaseX question - Enhancing JAX-RX interface
by Jan Vlčinský (CAD) 26 Feb '11

Hi Christian I did try to write my ideas, but landed at reading what is REST and what not - and run out of time. So here is draft of some of ideas - unfortunately without clear proposal for next action, but someone will probably take it over and move on. Jan JAX-RX and BaseX - Aim - Summarize ideas and requests regarding JAX-RX interface of BaseX database - Topics - Mixing commands and queries in one request - Get and relevant post implementation without breaking compatibility - Are we REST like and do we need it? - What processing context we need - Typical Use Cases - Add document(s) and optimize - why - Want to be sure, that indexes will be updated after collection has been modified and no one will have a chance to run a query on not optimized collection - Updating query and optimize - why - Want to be sure, that indexes will be updated after collection has been modified and no one will have a chance to run a query on not optimized collection - Query with client defined timeout - why - It is better to quit too long query then risking that one too expensive query would endanger overall server performance There is no need to get query results too late, when our http connection already timed out - Set of independent simple expression queries - Mix updating and simple expression queries - Set of independent commands - why - Needing to run a batch of tasks, which cannot be interrupted by other clients - Ideas - add timeout parameter to each request - check, what other timeout-like parameters we may need - introduce new request element for POST, mixing queries and commands - Possible problems - compatibility with existing design - wish to pass query result into next command/query 2011/2/24 Christian Grün <christian.gruen(a)gmail.com> > > OK, I understand, that REST allows to perform the (SET) command, but to > use > > it with a query, I have to send the query in another, following, request. > > Will this second request keep enough context at the server side to know, > it > > shall use that timeout? > > Just recently, I've thought about extending the JAX-RX Interface to > allow more than a single query or command, or to allow both commands > and queries; regarding the syntax, this could be easily realized for > the GET method: > > http://localhost:8984/basex/jax-rx/factbook?query=1&query=2 > > http://localhost:8984/basex/jax-rx/factbook?command=set+timeout+1&query=1&c… > > On the other hand, I haven't decided yet how to best realize it for > the POST method without giving up compatibility.

Re: [basex-talk] Mixing non-updating and updating expressions in a single query
by Sony Vijay 25 Feb '11

25 Feb '11

@Christian and Lukas: Many thanks for helping me with the transform expression so far. However, I am not sure if we can use both non-updating and updating expressions in a single query ? Meaning, I am trying to modify one document and insert the modified document into the second document. *Example:* let $newchild := "This is a child node" copy $c := <entry><title>How to use updating and non-updating expressions together</title> <child>child 1<child> <child>child 2</child> </entry> modify ( for $child in $c//child return replace value of node $child with $newchild ) return insert node $c into doc('seconddocument') I also tried: let $newchild := "This is a child node" copy $c := <entry><title>How to use updating and non-updating expressions together</title> <child>child 1<child> <child>child 2</child> </entry> return modify ( for $child in $c//child return replace value of node $child with $newchild ) insert node $c into doc('seconddocument') Of course, I can achieve this when I use two xqueries (one to return the modified document and the other to insert it into a second document). But, it would be great if I could perform both actions in a single query.

Re: [basex-talk] Use of For loop in transforming a node without changing the database

Christian, Thank you very much for helping me with the query. However, I am not quite sure how the transform operation works if I have to use a for loop.

Re: [basex-talk] BaseX question
by Christian Grün 24 Feb '11

24 Feb '11

Hi Phil (cc'ed to the list), as far as I can judge, XQuery expressions are too heterogeneous to provide realistic cost estimations. While our query compiler has some notion of "costs", those values are all relative, and used to select the (presumably) cheapest query plan or index access. The same applies to the estimation of query results: the costs and size of single XQuery results can vary a lot, as a single result node can span several MB, while a single atomic item may just take a few bytes. Hope this helps (at least a little), Christian ___________________________ > Hi Christian - is there a way to perform a low-cost (very fast) estimation of the amount of time a particular query would take without actually executing the query? In a server environment this is extremely useful. I would like to be able to rapidly check that queries will not be issued which exceed a certain execution time (roughly or even very roughly - e.g. on the order of a second vs. on the order of 100 or 1000 seconds.) Since my queries are going to be dynamically generated based on user supplied parameters this is an issue. A related issue is estimating the number of nodes retrieved as a result of a given query (again without actually executing it.) The estimation would not have to be very exact.

Hi there, I just installed baseX 6.5.1 on a windows vista machine. Well, after installation my %PATH%-variable just contained exactly one entry: "C:\Program Files\BaseX\bin". The rest of my original path variable was removed by the installer... :-( Best regards, Marcus Beranek

Hello, I am facing problem while deploying BaseX under JBoss due to JBoss’s (Virtual File System) for the I/O operations. So “ClassLoader.getResource” under JBoss context returns JBoss resource and then getContent() returns “JBoss Stream” but not the java.io.InputStream, this can be fix by using getResourceAsStream which returns InputStream Changes required in org.basex.core.Lang.java at Line No: 66 ----------------------------------------------------------- final BufferedReader br = new BufferedReader(new InputStreamReader( (InputStream) url.getContent(), Token.UTF8)); ----------------------------------------------------------- Above line needs to be replaced with below: --------------------------------------------------------------- InputStream stream = Lang.class.getResourceAsStream(path); final BufferedReader br = new BufferedReader(new InputStreamReader( stream, Token.UTF8)); --------------------------------------------------------------- Regards, Ashish Jain

Hi I noticed, many answers in this forum got shortened a lot in last weeks into simple short url pointing into wiki. For couple of years I use simple trick to search quickly terms in Wikipedia - it works for me on Firefox as well as nowadays on Google Chrome (other browsers will probably work that way too). - using keyword en, pressing Tab, entering searched term on English Wikipedia and pressing enter I get the page I need - the same with cs for Czech Wikipedia - *Today I added bx for BaseX Wiki as I found myself searching this site so often* Chrome allows to control this by wrench tool - first tab (Basic) - section Search - button Manage en - http://en.wikipedia.org/w/index.php?title=Special:Search&search=%s bx - http://docs.basex.org/index.php?title=Special:Search&search=%s&go=Go Now I have (almost) all the knowledge of BaseX team at my fingertips - thanks for it DBIS team. And thanks to those, who are willing to share their knowledge on this wiki. Jan

Adding new doc into existing collection by means of XQuery

Hi Is there any method, how to add new doc into existing collection? I studied XQUF and it seems, like it can only update existing nodes. Options I was thinking about are - fn:put() - it is supposed for publishing into external documents, but if I could use uri of collection in BaseX and BaseX would accept it... - using database functions<http://docs.basex.org/wiki/Database_Functions>, but also here I do not see anything, what would add a doc The motivation is simple - if I could add docs by XQuery, I can save some roundtrips of data to insert Workaround is also not so difficult - simply using some sort of container doc in target collection and then modifying its nodes (putting here content of complete logical doc) instead of adding complete doc. Any comments are welcome. Jan
