#31415 proposed an option to show import timings. The output is primarily designed for humans. I propose to instrument importlib with two dtrace hooks: probe import__find__load__start(const char *) probe import__find__load__done(const char *, int); arg0 is the absolute module name as UTF-8 string. arg1 of import_find_load_done probe indicates if the module was found (1) or import failed (0). |
