Hi Eliot,

Thanks for the pointer that led me to update the documentation:

We returned “something like a stack trace” in a previous version of BaseX, but the result was often misleading: Functions are inlined and simplified at compile time, and it’s often not possible to return a stack trace representation at runtime that reflects function calls of the original query. This is why we eventually dropped this information.

During development, though, it can be helpful to assign 0 to the INLINELIMIT option. This way, function inlining is disabled, and the returned stack traces (without try/catch) make more sense. However, queries without inlining may run much slower than standard ones.

Hope this helps, Christian

The docs for Try/Catch in in the XQuery_3.0 page say:

· $err:additional: error stack trace

However, in my testing, this only returns the place where the error was thrown, not the complete stack trace as is shown e.g., in a web app when an exception is thrown.

Is it possible to get the stack trace in XQuery? I didn’t find anything searching on the BaseX-supplied DBA app.

Thanks,

E.
