It's a bit convoluted, but the file is actually deleted before the `os.stat` call. Because there are no references to anything but the `name` (which is just a string), the `_GeneratorContextManager` (result of `my_tmp_file`) and the `_TemporaryFileWrapper` (result of `my_tmp_file().__enter__()`) are both destroyed. Because `NamedTemporaryFile` is called with `delete=True` (default), the `_TemporaryFileWrapper` has a `_closer` attribute which is a `_TemporaryFileCloser`, which calls `self.close()` in `__del__`, which deletes the file. If a reference to the result of `my_tmp_file()` is saved anywhere along the way, none of the objects are destroyed and the file still exists. This also wouldn't happen in an implementation without reference counting. ---------- nosy: +zach.ware resolution: -> not a bug status: open -> pending _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45833> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
