Out of memory bug
by Ivan Lagunov 31 Jul '13

31 Jul '13

Hello, I've got 'Out of memory' error and corrupted database again, this time it's for 6.3 version. Steps: 1. Started server, started terminal client, checked there are no text and attribute indexes. 2. Started my Java application that runs several tests on database: querying, adding, removing. 3. Then I forgot to reopen terminal client and used the one that I opened in Step 1. 4. Run optimize command for the collection and got error. 5. Cannot open the collection any more as I'm getting 'Out of memory'. It's clear that I shouldn't have used the terminal client that I opened before execution of my Java application. But sometimes it's hard to remember. And it's completely unacceptable that these actions result in the corrupted database. You really should catch ArrayIndexOutOfBoundsException everywhere in order to save database from being corrupted. Terminal client stacktrace: > optimize Possible bug?

deadlock in BaseXServer 6.2.7

Hi, we're observing that our BaseXServer 6.2.7 deadlocks. The stack traces are here: http://top.cs.vt.edu/~gback/bx/deadlock-6.2.7/basex-deadlock.txt Could you take a look to see if these ring any bells? Has this problem been addressed in a more recent version? - Godmar

Problems in using BaseX REST server - IncompatibleClassChangeError javax.ws.rs.core.Response$Status does not implement the requested interface

Getting the document path in a collection using XQuery
by chas＠munat.com 30 May '11

30 May '11

Say I have a collection c with xml documents x.xml, y.xml, and z.xml and that I've added them using "to" so that they are found here: collection('c/x') ... Let's say that in each document I have a node <code/>, so in x.xml I have <code id='1'/>, in y.xml I have <code id='2'/>, etc. I can query across the documents to find the <code/> node with id = 2 pretty easily. But now that I've found it, I want to do further queries limiting myself to that document. In other words, I want to learn using XQuery that the <code/> node with id = 2 is in collection('c/y'). How can I do this? TIA, Chas.

Hi Christian, Thank you for looking at the query. You are always a great help! The result I am looking for is the total number of occurences. Because there is such a large repository of letters. With this number I am able to say that the word 'zonnebloemen' occurs 30 times in all documents. For example. I thought this could be accomplished with a small alteration of this query. If you see a solution that would be great, otherwise I just count them by hand.

adding zip contents – bug or feature?

When I add a directory to a database in 6.6.1 using the plain *.xml createfilter, and when there's a zip file below this directory, the zip file's contents will be indexed, too, as if they reside in the server's working directory. If this is a feature, how can I switch it off? Gerrit
