[PATCH 017/608] dealloc and finalize_modules (#6934) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * rewrite finalize_modules with phased algorithm Replace the absence of module finalization during interpreter shutdown with a 5-phase algorithm matching pylifecycle.c finalize_modules(): 1. Set special sys attributes to None, restore stdio 2. Set all sys.modules values to None, collect module dicts 3. Clear sys.modules dict 4. Clear module dicts in reverse import order (2-pass _PyModule_ClearDict) 5. Clear sys and builtins dicts last This ensures __del__ methods are called during shutdown and modules are cleaned up in reverse import order without hardcoded module names. * dealloc the rigth way * fix finalize_modules: only clear __main__ dict, mark daemon thread tests as expected failure Without GC, clearing all module dicts during finalization causes __del__ handlers to fail (globals are None). Restrict Phase 4 to only clear __main__ dict — other modules' globals stay intact for their __del__ handlers. Mark test_daemon_threads_shutdown_{stdout,stderr}_deadlock as expected failures — without GC+GIL, finalize_modules clears __main__ globals while daemon threads are still running.

(#6981) - Add FieldType enum and FIELD_TYPES static table mapping all AST node classes to their ASDL field types - Resolve markers to real Python type objects (GenericAlias, Union, plain types) at module init in populate_field_types() - Set class-level None defaults for optional fields - Replace hardcoded LIST_FIELDS and class-name checks in slot_init with _field_types-based lookup - Add expr_context default to Load(), fix ImportFrom.level default (now None instead of 0) - Fix __class_getitem__ None check, compile() formatting - Remove 14 @expectedFailure decorators from test_ast ---
