Brian Moyles added the comment: I ran into the same problem when running the test suite against a fresh Python 3.6.2 build on Ubuntu 16.04. It specifically appears to be a problem with ndbm and retrieving an empty byte string value:
Python 3.6.2 (default, Sep 8 2017, 18:31:28) [GCC 5.4.0 20160609] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import dbm.gnu, dbm.ndbm >>> g = dbm.gnu.open('gnudb', 'c') >>> g['0'.encode('ascii')] = b'' >>> g.keys() [b'0'] >>> g['0'.encode('ascii')] b'' >>> >>> n = dbm.ndbm.open('ndbm', 'c') >>> n['0'.encode('ascii')] = b'' >>> n.keys() [b'0'] >>> n['0'.encode('ascii')] Traceback (most recent call last): File "<stdin>", line 1, in <module> KeyError: b'0' Same behavior when using the distribution's stock Python 3.5.2 so I suspect there's a behavioral change in libdb that's not accounted for? ---------- nosy: +bmoyles _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31026> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
