Category: Unicode Group: None Status: Closed Resolution: Invalid Priority: 5 Submitted By: Joe Wreschnig (piman) Assigned to: M.-A. Lemburg (lemburg) Summary: Broken __hash__ for Unicode objects Initial Comment: http://docs.python.org/ref/customization.html says equal objects should hash to the same value. But this is not the case when the default Unicode encoding has been changed (by e.g. importing PyGTK). Using Python 2.4.2: >>> import sys >>> reload(sys) <module 'sys' (built-in)> >>> sys.setdefaultencoding('utf-8') >>> hash(u"\u1234"), hash(str(u"\u1234")) (-518661067, -1855038154) >>> u"\u1234" == str(u"\u1234") True ---------------------------------------------------------------------- >Comment By: Joe Wreschnig (piman) Date: 2006-03-29 22:03 Message: Logged In: YES user_id=796 What's the point of having a default encoding if it breaks a fundamental part of the language on anything but the default value? I mean, I can tweak site.py to set it to utf-8; does this become a valid bug then? site.py even contains a check to set the encoding to an alternate value if I want. This may be a "known fact". Every reported bug is a known fact. That doesn't mean it's not a bug. ---------------------------------------------------------------------- Comment By: M.-A. Lemburg (lemburg) Date: 2006-03-29 19:54 Message: Logged In: YES user_id=38388 This is a known fact. When changing the default encoding, you are basically on your own, so there's nothing much we can about it. BTW, the above hack that you're using to get at the sys.setdefaultencoding() API already indicates that you're leaving the path of standard Python. We deliberatly remove that API from the sys module in site.py to make changing the default encoding an explicit task. If importing PyGTK has the side-effect of applying such a hack, then PyGTK is seriously broken and you should report this to their developers. Closing as "Invalid". ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1460886&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
