Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Darryl Dixon (esrever_otua) Assigned to: Nobody/Anonymous (nobody) Summary: getpass.getpass() performs differently on Windows vs *nix Initial Comment: getpass.getpass() on *nix platforms allows users to input unicode characters and other NLS input. getpass.getpass() on Windows only allows ASCII input in the 0-127 codepage range. This means that getpass can not be used cross-platform for complex passwords. ---------------------------------------------------------------------- >Comment By: Reinhold Birkenfeld (birkenfeld) Date: 2005-07-07 12:01 Message: Logged In: YES user_id=1188172 First of all, don't accuse me of lying. If I wanted to lie professionally, I would have become politician, not programmer. I'm German, and using a German keyboard layout which does have the ü, so it can be perfectly input. Your problem is that you cannot input characters which don't directly create keycodes on the keyboard, but must be copied to the console in some way. In python-dev, you said that msvcrt.getch() would have to call _getch() a second time in the case that it returns 0x00 or 0xe0 the first time and/or return a Unicode string. First, the documentation for _getch() says that this is a special case for arrow and function keys (such as F1 or <Up>). These keys don't have a representation in any character set, as they are control keys, so how would you represent them as Unicode? Second: In my console, pressing F7 yields the return values "\x00" and "A". When the 0x00/0xe0 read the first time is secretly swallowed, the user of msvcrt.getch() can't know whether the user pressed "A" or F7. That said, the behaviour of getch() is documented and correct. But how does that all help you with your original problem, which is that _getch() doesn't help you with Alt+XXXX sequences or console window Copy-Paste? In my understanding _getch() only works with characters directly input to the console. Sorry, but then this is not a Python problem but a Windows one. ---------------------------------------------------------------------- Comment By: Darryl Dixon (esrever_otua) Date: 2005-07-07 11:18 Message: Logged In: YES user_id=567623 I think that, because I've read the source, and getpass.getpass() uses msvcrt.getch() on Windows, which doesn't support anything at all above ASCII 255. Also because I have a bug report pending against one of the projects that I maintain from a user that is experiencing a problem because of exactly this issue. See: https://sourceforge.net/tracker/index.php?func=detail&aid=1224877&group_id=69259&atid=523935 Also, I call shenanigans on your claim of successfully inputting an umlaut-u into getpass.getpass(); this character can *theoretically* be input, as it's below ASCII 255, but in practice I can neither input it directly, nor COPY+PASTE it from the clipboard on my WinXP SP2 with Python 2.4.1 installed. Finally, regardless of whether "ü" works or not, other characters that live solely in unicode, such as "¿" most certainly do not (and never will) work (not even theoretically).

I tried it on Windows XP, in a cmd.exe session. I could enter, for example, an ü (umlauted u), which in the resulting string came out encoded as \x81, as is correct in the encoding used by the console window, namely cp850. I could then convert this to latin1 by using s.decode(sys.stdin.encoding).encode("latin-1"). ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1233785&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
