I'll explain what it is, how it (A dynamic array automatically expands when adding new elements, unlike a normal C array.) Here's the . Garbage collection; Reference Counting; Automatic Reference Counting. Emoticon:cat In my post about ShedSkin a couple of days ago I said that I was unsure how ShedSkin handled memory management and whether it has any sort of garbage collection. NewLISP also does references passing by packaging variables into contexts. Their very existence tells me . The problem with garbage collection is that it solves only a subset of the overall problem set of dynamic resource management. Dynamic scoping style seems not to be a disadvantage when using the language, as long as you divide your code into context modules. Automatic garbage collection is the feature of dynamic languages which most reduces programmer headaches. If memory is freed automatically, the programmer loses at least some control over programs' resource usage. Compiler level feature; Also a run time Memory management can be broadly classified into two, garbage collected and reference counted models. One technique which can make memory management a lot easier is reference counting, which this article is about. From a user's perspective, newLISP's memory management works just like garbage collection in other scripting languages: memory gets allocated automatically and unused memory gets recycled. Of course depending on the implementation it can lead to less memory efficiency than hand coded C or C++. Like a lot of programming terms, this is a simple concept which has an odd name. If even reference counting is too tedious for you, then maybe you want garbage collection, which almost completely eliminates manual memory management — but garbage collection is way outside the scope of this article. Since are using a selector to call a method dynamically at runtime, ARC doesn't really know if the method called returns a +1 retained object or a auto-released object. ShedSkin Part II: Garbage Collection and Memory Management. Before going to the details, let's briefly .. A less than perfectly C++ smart pointers offer the possibility of a similar level of dynamic-memory safety as garbage collection, but with a different set of performance tradeoffs.
