Hi Donald, Did you try db:name()? See our documentation for more information [1].

quick and dirty guide to increasing memory capacity?
by C. M. Sperberg-McQueen 12 Jul '17

12 Jul '17

I’m working on some XQuery code for language corpora and testing a function that reads a corpus and gathers information about its contents. The function works fine on the one-million word Brown Corpus, but it’s failing with an out-of-memory error on the five-million-word Hamburg Dependency Treebank (the XML for which is somewhat more verbose than Brown’s). Before I spend a lot of time trying to rewrite the code to reduce memory usage: Is there a quick way to give the BaseX GUI interface more memory? Once the code is more complete, it will make sense to try to improve its speed and lower its resource consumption (and at that point I’ll surely have lots of questions for the list), but for the moment I would prefer to postpone such considerations, and focus on writing code I understand. Thanks! ******************************************** C. M.

Data Access out of bounds error when running XQuery on a databse
by Jason Ricles 11 Jul '17

11 Jul '17

I am running BaseX 7.9 (yes I know its old but for reasons beyond the scope of this we can't just update BaseX) on RHEL 6.9. The BaseX is not running any instance as a server but as a standalone application with its libraries being used with my java application. I am able to add new files to the database, but when I run an XQuery I get the following output: *error running xquery: declare namespace tr = '[query]org.basex.core.BaseXException: Improper use?

“You’ll become smart at the age of forty,” a Swabian saying goes („Mit 40 wird man g’scheid.“, see also [1]). If this is true, and if the (excellent) current system is the product of Christian’s pre-40 dabbling, how much more sophisticated will BaseX become from now on? Happy birthday, Christian!

Fwd: invalid entry compressed size (expected4294967295but got 13733720 bytes)
by Christian Grün 01 Jul '17

01 Jul '17

Hi Donald, I downloaded the referenced zip file, and I noticed indeed that various of the file meta data in the archive is invalid: The first zip entry has 13732320 bytes, but instead of E089D100 (little-endian), the compressed file size is set to FFFFFFFF. Moreover, I noted that the zip entries are not really compressed (although they are flagged as such), and I can reducing its size from 1,8 GB to 40 MB by zipping it again. Thanks for the zip4j pull request. I tend to stick with the default Java ZIP streams, because it seems to work fine if the input is valid. Maybe you have any chance to unzip the files before passing them on to BaseX?

Uppercase ß ?
by C. M. Sperberg-McQueen 30 Jun '17

30 Jun '17

From Die Zeit, I learn that new orthographic rules issued by the Rat für deutsche Rechtschreibung specify that ß / esszett / sharp s shall now have an uppercase form. From the comments there, I learn further that codepoint U+1E9E has already been assigned to this character. Will the default collation used for upper-case be changed to map U+00DF to U+1E9E? I notice that lower-case already maps U+1E9E to U+00DF, in the version 7.9 on my disk. (Am I already that far out of date? Sigh.) best regards, Michael Sperberg-McQueen -- **************************************************************** * C. M.

Dockerizing a BaseX app
by Richard Stanley 28 Jun '17

28 Jun '17

Hi, I'm dockerizing a BaseX app: https://github.com/openhie/openinfoman This has been done by others using an Ubuntu image but I'd like to do it with the official BaseX Docker image. I've had assistance here already (Thanks!): https://github.com/BaseXdb/basex/issues/1467 Modules can be mounted as volumes from the GitHub repo into the BaseXRepo and BaseXWeb container dirs just fine. But, there's an error suggesting that the namespace is confused when hitting the server, e.g.: Stopped at /srv/BaseXWeb/adapter.xqm, 3/85: [XQST0059] Module not found: https://github.com/openhie/openinfoman/csr_proc. I'm guessing that when modules are installed with 'basex repo install' the modules URIs are rewritten but this doesn't happen if they are only mounted. One solution is to install the xqms inside a container instead of mounting them. This fails because basex-api.jar is not in the classpath for the basex command inside the container. So, does this mean one must change the classpath/command to run basex for the container? If so, a hint here would be great and happy to educate myself. Best, Richard

Hello everyone, When I was creating database from a ZIP file in BaseX GUI, I encountered this problem. "W:/10-004/10-004.ZIP/10/20081212000000001000000000000000LEPRSEN20081212EP004/20081212000000001000000000000000LEPRSEN20081212EP004.XML"invalid entry compressed size (expected 4294967295 but got 13733720 bytes) Anyone have seen this one before? Does the baseX validate the zip entries before importing them? maybe disable the validating can bypass this error, is not it? By the way, how could I debug baseX GUI in Eclipse and how to print the stack trace of this error? Thanks a lot!

BaseX ordered results?
by Bram Vanroy 24 Jun '17

24 Jun '17

Dear list We were wondering if BaseX always returns the results in the same order, even when using an XQUERY position(). In other words, if we only request the first 10 results as defined by position(), will this *always* be the same results, or is it possible that each time it will be ten different results? Or will caching and indexing alter the way in which results are returned first? Thank you in advance Bram Vanroy https://bramvanroy.be

Strange behavior while adding existing elements into new element.
by Jan Dölle 21 Jun '17

21 Jun '17

Hi, just before you asking me. No we wasn't to isolate the Problem for now. Working on a complex transaction with database involved, we get the following phenomenon. declare function m:paths($el as element()) as xs:string* { distinct-values( for $e in $item/descendant::* return string-join($e/ancestor-or-self::*/local-name(.), "/") ) }; This function should produce a list of paths to all child of $el. And it works! But sometimes we get some strange results. We created new element constructed from others, may existing, elements. let $sequence-of-elements := collect-some-elements($from-somewhere) let $new-element := element el { $sequence-of-elements } return paths($new-element) Most of the time we get as expected results like: el/c1 el/c1/c12 el/c2 el/c2/c21 el/c2/c22 el/.. But sometimes it looks like that parents of the copied elements are not set correctly: oldParentOfc1/c1 oldParentOfc1/c1/c12 otherOld/ParentOfc2/c2 otherOld/ParentOfc2/c2/c21 otherOld/ParentOfc2/c2/c22 ... If we do a copy of the result <el> like parse-xml(serialize($new-element))/* and call paths() again, everything looks now as expected. We call the function what products such results, isolated within a test-script with exact the same inputs. But suddenly the result was correct. Then we copied the inputs of the function within the integration (parse-xml, serialize). But it failed again. Also notable is, that the "bad result" is stable. It produces always the same result on same inputs (no random). So we have no idea to isolate the issue. Any suggestions?

Problem with serialize function and use-character-maps option
by Martin Honnen 18 Jun '17

18 Jun '17

When I try serialize("This is a test with a slash / Test.", map { 'method' : 'json', 'use-character-maps' : map { '/' : '/'}}) with BaseX 8.6.4 is indicates an error [SEPM0017] Invalid 'use-character-maps' value 'map { "/": "/" }'; must be a string. However, the W3C spec https://www.w3.org/TR/xpath-functions-31/#func-serialize suggests the syntax is use-character-maps map(xs:string, xs:string)? with "For the use-character-maps option, the value is a map, whose keys are the characters to be mapped (as xs:string instances), and whose corresponding values are the strings to be substituted for these characters.". So it seems BaseX is not implementing the finalized spec here.
