New submission from amcinnes <an...@amcinnes.info>:
The documentation says SpooledTemporaryFile "operates exactly as TemporaryFile() does". seek() would be expected to return the new absolute position; this is what it does for TemporaryFile, and is the documented behaviour of seek() in IOBase. But for SpooledTemporaryFile it returns None. Probably trivial to fix by sticking a "return" on https://github.com/python/cpython/blob/0361556537686f857f1025ead75e6af4ca7cc94a/Lib/tempfile.py#L741 Python 3.8.2 (default, Apr 8 2020, 14:31:25) [GCC 9.3.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import tempfile >>> t = tempfile.TemporaryFile() >>> print(t.seek(0)) 0 >>> u = tempfile.SpooledTemporaryFile() >>> print(u.seek(0)) None >>> ---------- components: Library (Lib) messages: 366475 nosy: amcinnes priority: normal severity: normal status: open title: SpooledTemporaryFile.seek returns None type: behavior versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40287> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
