How Racket Handles Memory Management
- Racket dynamically allocates memory for data structures, functions, and control info, managed automatically without dev intervention.
- Racket's memory management involves stack and heap allocation optimized for specific data types and operations.
- Functions in Racket use the stack for local variables and control info, creating and removing stack frames during execution.
- Racket distinguishes between boxed and unboxed values for performance optimization during memory allocation.
- New objects in Racket are initially allocated in the young generation, with promotion to the old generation based on usage and references.
- Custom structures in Racket are stored in memory to optimize access and assist the garbage collector in efficient memory management.
- Large objects like arrays are allocated directly in the old generation to minimize copying during garbage collection.
- Racket uses memory alignment and object promotion techniques to enhance memory access and allocation efficiency.
- Generational garbage collection, mark-and-sweep algorithm, and compaction are vital parts of Racket's memory management system.
- To handle circular references, Racket's garbage collector employs a tracing collector that correctly identifies and removes unreachable objects.
