[Mono-dev] Need Help on Commons.Xml.Relaxng.dll

[Panop Suvaphrom]

Hi,
 
        I have used the Commons.Xml.Relaxng.dll in VS2010. 
        I also think that the memory is going up especially when validation exception occurred. 
        When profiling on .net memory profiler, I can see many of Commons.Xml.Relaxng.Derivative.
 
       Not sure about this, Do I miss something ?

Thank You,
Panop S.

Hello,

That's an interesting page. I didn't know that and am pretty glad to see it :)

Hmm, but that sounds weird. I tried some of the samples on that page with mono --profile (simpler one), but cannot see such huge memory consumption. Can you show me the --profile result (or any profiling stuff) ?

Commons.Xml.Relaxng is based on James Clark's derivative algorithm[*1] and I have implemented all the optimization trick such as avoiding exponential blowup and memoization. There could be of course bugs that prevents them though.
