Ruby husimamia memory kiotomatiki kupitia garbage collector (GC) inayotwaa tena objects ambazo hazirejelewi tena. Ruby ya kisasa (MRI) hutumia collector ya generational, incremental mark-and-sweep yenye compaction. Kuielewa husaidia katika utendaji na kutambua matatizo ya memory katika applications zinazoendeshwa kwa muda mrefu.
Garbage collection ya kiotomatiki
Ruby allocates objects on the heap; the GC reclaims those that are no longer REACHABLE
(referenced). You never free memory manually.
Modern MRI GC characteristics:
✓ Mark-and-sweep — marks reachable objects (from roots), sweeps unreachable ones
✓ Generational (since Ruby 2.1) — new objects collected often, old ones rarely
(based on "most objects die young")
✓ Incremental — spreads GC work to reduce pause times
✓ Compacting (GC.compact, Ruby 2.7+) — reduces memory fragmentation
