Hi all,
it seems that this bug is linked to the introspection module. I isolated a
code that produces on my config a exception, see at end of mail.
Note :
- It seems to be a regression, as this code worked finely with the 3/12
version of BaseX.
- It took me a whole day to isolate this exception. This "overhead" is due
to the JAVA catch / raising exception BaseX mechanism, letting the user
blind with its XQUERY code. As bugs are becoming harder and harder to spot,
maybe we should think about a way, or a tool, to easen trace / debug while
the interpreter raises a JAVA exception ?
Cheers
declare function local:map_inspect_functions() { map:new(for $fun in
inspect:functions() return map:entry(local:name-function($fun),$fun)) };
declare function
local:name-function($fun){fn:data(inspect:function($fun)/@name)};
declare function local:get_void() { function(){ () }};
declare variable $local:MapIntrospecting := local:map_inspect_functions();
let $fun_2 := map:get($local:MapIntrospecting,"local:get_void")
return count($fun_2())
Improper use? Potential bug? Your feedback is welcome:
