CPython Internals
CPython-Internals este un ghid tehnic de implementare și referință pentru interpretorul CPython. Oferă o analiză detaliată a codului sursă C intern și a arhitecturii, concentrându-se pe logica care guvernează comportamentul interpretorului.
Proiectul documentează modelul de obiecte Python și pipeline-ul de compilare, urmărind procesul de la gramatica brută și arborii de sintaxă abstractă până la bytecode-ul executabil. De asemenea, servește ca referință pentru dezvoltarea extensiilor C, explicând cum să interfațați cu structurile de date interne și să utilizați API-ul C.
Materialul acoperă gestionarea memoriei, inclusiv numărarea referințelor și garbage collection-ul generațional, precum și funcția global interpreter lock (GIL).
