[Squeak-dev] Slowdown with required methods...

Hello,

As you probably noticed, the 'required' dynamic protocol slows down  
the code browsing.
The method DynamicProtocols class>>collectAllProtocolsOnClass: aClass  
has the following comment:
"Returns a collection of all dynamic protocols that should be displayed
        for the current class.
        Only non-empty protocols are returned"

Although it makes sense to display non-empty protocols only,  
DPRequired makes a significant slowdown because required methods have  
to be computed to determine if this dynamic protocol has to be  
displayed or not.

What about defining a hasRequiredMethod in Behavior? I guess this  
will remove the slowdown...

Regards,
Alexandre

Hi Alexandre,

I think the problem comes from the non-optimal algorithm which
computes the required methods. The algorithm must cache its result and
answer efficiently. The problem is that I don't have enough knowledge
to correct it. It's the Nathanael's algorithm which is included in
3.9.
