ShedSkin Part II: Garbage Collection and Memory Management. One of the most common mistakes that new programmers make when dealing with dynamic memory allocation is to use delete instead of delete[] when deleting a dynamically allocated array. Compiler level feature; Also a run time Memory management can be broadly classified into two, garbage collected and reference counted models. Automatic memory management, also known as automatic garbage collection, is the practice of allowing the language implementation to keep track of used and unused memory, freeing the programmer from this burden. Before going to the details, let's briefly .. There are various technique for getting around this behavior (as mentioned, reference counting and garbage collection), some of which C++ support and some of which it doesn't. 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. 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. LISP in 1959 started a new technique called Automatic Memory Management known by the more popular term Garbage Collection (GC). Memory allocated dynamically had to be managed carefully because if allocated memory is not de-allocated after it's use is over, it becomes garbage and un-available (called memory leak) and slowly runs out of space. Something that is worth looking into is smart pointers (there C++ uses RAII ( Resource Acquisition Is Initialization) programming idiom, there is nothing like automatic memory management known as Garbage Collector in java or AutoZone in Objective-C 2. Automatic garbage collection is the feature of dynamic languages which most reduces programmer headaches. Garbage collection; Reference Counting; Automatic Reference Counting. Of course depending on the implementation it can lead to less memory efficiency than hand coded C or C++. You either have to explicitly delete the objects (if in dynamic storage) or they will be deleted automagically (but not by the garbage collector) if in automatic storage. Java classes can have a finalize function. In languages without automatic memory management, the In contrast, C++ programmers manually specify where an object with dynamic extent is to be reclaimed by coding a delete statement. Using the scalar version of delete on . Memory Management: Algorithms and Implementation in C/C++ presents several concrete implementation of garbage collection and explicit memory management algorithms.
