New submission from Petr Viktorin <encu...@gmail.com>:
The ZIP format cannot handle times before 1980. Issue6090 provided a nice error message for trying to add such files. I'm seeing a system for reproducible builds that sets mtime to 1970 (zero UNIX timestamp), resulting in files that Python can't package into (zip-based) wheels. At least here on Fedora, the `zip` command-line utility silently bumps old timestamps to 1980-01-01. Of course, silently corrupting data would not be good default behavior for Python. But in many cases timestamps don't matter. It would be nice to give ZipFile and ZipFile.write() a `strict_timestamps=True` keyword argument that could be turned off. ---------- components: Library (Lib) messages: 321460 nosy: petr.viktorin priority: normal severity: normal status: open title: ZIP does not support timestamps before 1980 versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34097> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
