STINNER Victor <victor.stin...@haypocalc.com> added the comment: I don't like the idea of adding new fields to os.stat() *by default* because it may break backward compatibility. And if the new fields are decimal.Decimal objects, the module has to be imported and it means that any call to os.stat() would be slower just to provide timestamps with a finer resolution: this is not acceptable if you just want to check if a file exists.
In the issue #13882, I propose to add a format argument to functions getting time (time.time(), time.clock(), etc.). My patch doesn't change the default type, but add a "decimal" format to get time as a decimal.Decimal object. The option (format) value is a string to be able to add other formats without having to change the API later: - "decimal": decimal.Decimal object - "datetime": datetime.datetime object - "tuple": low-level value, (intpart: int, floatpart: int, divisor: int) - "float128" - etc. For os.stat(), the optional argument can be called "timestamp". So if you want timestamps in the best available resolution, use timestamp="decimal". If you prefer the datetime API, use timestamp="datetime". If you don't care of timestamps, just call os.stat() without setting the timestamp option ;-) We might add a registry to add user-defined types, but the "tuple" format should be enough. (I don't know if we need to expose the low level "tuple" format.) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11457> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
