Hi During KohaCon, Plack and Data persistance was discussed and wome work was done on that. Ian posted a perl script. Marc did another script. It works quite fast. I wanted to publicise this in order to contribute code so that eventually all the circular references could be solved. Find enclosed both scripts : CIRCDeps.pl from Marc and dep_check.pl We will try and keep you informed of what we achieved with that.
Unfortunately (if i'm reading correctly) this will only find modules that have circular dependencies on other modules. Yes, both (Ian and Marc scripts) are investigating Circular Modules references.
What causes memory leaks is circular references in the code, where an object refers to an object that refers to the inital object (or to another object that refers to it).

These are much harder to find. But there is a module that can help us http://search.cpan.org/dist/Devel-Cycle/lib/Devel/Cycle.pm
I am aware of Devel::Cycle, but I doubt we have circular objects references other than Modules, since Koha has mostly been procedural and not object oriented.
When I say object, I dont mean an Object in the Object Oriented approach, but a thing, it could be a hashref, that references a hash, that contains a reference to the first hash. Id find it highly suprising if we didn't have at least a few of these. Chris
