Forum OpenACS Development: Re: How to handle dotlrn-specific changes in core?

Posted by Andrew Grumet on
I agree that SC's are costly.  But callbacks as an idea can be cheap.  Maybe part of the problem is the SC implementation.  We might consider a lighter-weight, nsv-based thing that maintains a list of procs to call, each added to the nsv by the appropriate package-init.tcl script, with the arglist handled either by convention or passed through global scope.  If lighter weight, I wouldn't have a problem with callbacks that were only hooked into once, because the abstraction would be well worth it.  Still thinking...
