Dear Michael Sperberg-McQueen, thanks as usual for your concise feedback, and sorry for the delay and the fact that I cannot tell why the error occurred in your particular case. In earlier versions of BaseX, problems like this sometimes happened if multiple GUIs with the same database instance were opened at the same time (as each GUI runs in its own JVM, no synchronization took place). If the problem should happen again with the latest version, we'll be glad to spend some more time in investigating the problem. All the best, Christian ___________________________ On Sat, Mar 31, 2012 at 3:19 AM, C. M. Sperberg-McQueen <cmsmcq@blackmesatech.com> wrote:

[2d posting - this time with the promised attachment]

I got some error messages today which seem to indicate a problem, either in BaseX or in (my understanding of) the documentation.  Since the error messages (in the attached log) suggest contacting you about it, I am doing so.

The document at http://www.w3.org/TR/xsd-unicode-blocknames/ includes a table of Unicode block names created by querying a database consisting of XML representations of the various versions of the Unicode Database.  Today I noticed that a new version of the Unicode Database was issued in January, and so I downloaded the XML data and added the document to my existing BaseX database of Unicode information.  The command seemed to run successfully, but when I ran my old query, I got an error message saying "Data access out of bounds".

I installed version 7.2 then, which gave the same error message.

Rebuilding the database from scratch allowed me to run the query without any problems, so I don't actually have a problem at the moment.  But I'm sending this problem report in the hopes that it may help you diagnose either a problem with dynamic adds to a database or perhaps a problem with the server command language documentation (it's entirely possible that I did something wrong when adding the new document to the database).

If there is any information I can provide that would be helpful, please let me know.

best,

Michael Sperberg-McQueen
