Hello,

To complete the previous threads :

1) I forgot a definition : declare function local:call($fun,$args) {$fun($args)};

2) The same behavior seems to occurs with the following code, not involving try catch expression :

declare function local:test($i){fn:for-each(1 to $i, function($a){2*$a})};

declare variable $test := prof:time(local:test(10000000),false(),"2 :");

prof:time(count(local:test(10000000)),false(),"1 :"),count($test)

Output :

2 :2508.42 ms

1 :710.51 ms

Hello all,

I wrote some basic debugging / profiling tools for xquery code, using try{} catch *{} mechanisms. However, profiling tools are not reliable.

The suspected reason is that inlining is not activated in try catch expression. If confirmed, is it a desired behavior ?

Here is the basic test :

declare function local:test($i){fn:for-each(1 to $i, function($a){2*$a})};
declare function local:fun-profile($fun,$args) {try{local:call($fun,$args)} catch *{()}};
declare function local:fun-profile2($fun,$args) {local:call($fun,$args)};

With default options (ie inlining activated)

prof:time(count(local:fun-profile2(local:test#1, 10000000))) Output : 683.12 ms
prof:time(count(local:fun-profile(local:test#1, 10000000))) Output : 2465.47 ms

With inlining desactivated (ie INLINELIMIT=0)
prof:time(count(local:fun-profile2(local:test#1, 10000000))) Output : 2480.32 ms
