Of course depending on the implementation it can lead to less memory efficiency than hand coded C or C++. In this session the Automatic variables (and function parameters) are usually stored on the stack. Perhaps this was a decent reaction to the memory management of C, but as a whole, in general purpose languages, garbage collection is more of a detriment than a benefit. Furthermore, the simplified model requires hiding the true nature of memory making it more difficult to implement certain inter-process and concurrent programming algorithms. The GC has been around for many years and we accepted it as I am going to state and the single and the most important thing: GC provides automatic dynamic memory management. An alternate approach to memory management that is now commonly utilized, especially by most modern object-oriented languages, is automatic management by a program called a garbage collector“ There are various Garbage Collection algorithms and each platform implements its own. The stack is normally located . I used to read article like the one on C++ User Journal about the “The Rule of Three” or rule of thumb like if you dynamically allocate memory you need the Rule of Three. It's certainly traditional though; e.g. 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. Another case where people confuse the mechanism with the goal. When I wrote a garbage collector for a toy project, I used the twospace algorithm for its simplicity. The CLR comes with a garbage collector (GC) which is a great thing. We need so, we write atomic in front of the operation name. As a consequence GC prevents the problems that were (and still . Automatic garbage collection is the feature of dynamic languages which most reduces programmer headaches. Back to basics: Series on dynamic memory management. This defragmentation may occur when a memory allocation fails or there may be a periodic garbage collection process that is run. Dynamic memory allocation tends to be nondeterministic; the time taken to allocate memory may not be predictable and the memory pool may become fragmented, resulting in unexpected allocation failures. Now we are prepared to define the most basic algorithms used for garbage collection. ShedSkin Part II: Garbage Collection and Memory Management.
