Hi Omar,

Thanks for your observation.

We have removed the BaseX-specific string output, as it was redundant. You should be able to reproduce the old output as follows (using the new XQuery 4 string template syntax):

`Stopped at { $err:module }, { $err:line-number }/{ $err:column-number }:
{ $err:description }`

As you’ve already discovered the responsible commit, you may have discovered the new XQuery 4 $err:map variable: It bundles all other error values into a single variable.

And @Martin Honnen thanks for mentioning fn:stack-trace. The function is still under discussion and might be dropped again: The specification gives processors much freedom in optimizing its expressions, so it’s hardly possible to define the function in a way that’s not completely implementation-defined.

Hope this helps,

Christian

I think stack traces were removed in this commit from basex-core/src/main/java/org/basex/query/expr/Catch.java

I get: Unknown function: fn:stack-trace() when I use stack-trace().

Ah, sorry, it looks like it is not yet implemented. Wait for Christian to give you hopefully some better info than my ill guess.
