Chengyi Zhao 2e00356c98 lib: core: add prepare_shutdown vfunc to fix Lua GC crash on exit ... When WirePlumber exits, it crashes with SIGABRT. The backtrace shows: 7 g_closure_invalidate 10 g_object_unref 15 g_value_unset 16 _wplua_gvalue_userdata___gc 26 close_state (lua_close) 27 wp_plugin_deactivate 33 wp_registry_clear 34 wp_core_dispose Root cause: lua_State is referenced by both the main plugin and each WpLuaScript object. During registry cleanup, scripts call lua_close again on an already-destroyed state, causing use-after-free. Fix: - Add a prepare_shutdown vfunc in WpPlugin. Call it from wp_core_dispose *before* clearing the registry. - Lua plugin implements prepare_shutdown to close its lua_State early, allowing all __gc finalizers to run while GObjects are still alive. - Then clear the lua_State pointer from every WpLuaScript object via wp_lua_script_clear_lua_state(). - Guard WpLuaScript finalize to skip if pointer is already NULL.		2026-05-08 14:44:44 +08:00
