Curious "Stack Overflow: Try tail recursion?" error message
Hi, Using a fresh install on 8.3.1 and running basexgui.bat on windows. I install this expath package https://github.com/expkg-zone58/ex-xparse/releases/download/v0.0.5/ex-xparse... Then, paste the following code into an editor window.. ------------------------ import module namespace xp="http://expath.org/ns/xparse"; "http://www.xqueryfunctions.com/xq/functx-1.0-doc-2007-01.xq" !unparsed-text(.) !xp:parse(.,map{"lang":"xquery"}) ----------------------- The result is the error... Stack Overflow: Try tail recursion? The curious part is.. if I keep retrying by clicking the execute button - after around 10 tries it starts working and seems to continue to work every time after that within that GUI instance. I have reproduced this on another pc. /Andy
Hi Andy, Sorry for the late reply. I can reproduce the behavior you have been describing, and I agree it’s quite surprising. I have no idea what’s the reason for that; my assumption is that the Java stack size is increased after a while (?). As you may know, the stack size can be increased via an JVM option in the BaseX script. With -Xss2m, your query will be successfully executed with the first run. Hope this helps, Christian On Thu, Nov 12, 2015 at 10:13 PM, Andy Bunce <bunce.andy@gmail.com> wrote:

Thanks for the reply. I had not thought that this is really just the Java stack. After reviewing the code I noticed the XQuery parser was created some time ago. The new version runs with the default stack for me [1] /Andy [1] https://github.com/expkg-zone58/ex-xparse/releases/tag/v0.2.1 On 20 November 2015 at 12:38, Christian Grün <christian.gruen@gmail.com> wrote:
