We only enable 8-bit output for known single-byte locales, currently
ISO8859-*. For all other locales the program output is unchanged.
RFC-1288 recommends that administrators have a mechanism to enable
characters greater than ASCII 126. A suggested solution is an
environment variable. The environment variables of choice here are
LC_CTYPE and LANG.
Thanks to Martin Husemann <martin@duskware.de> for the idea on checking
for known single-byte locales, to Johan Danielsson <joda@pdc.kth.se> for
checking RFC-1288, and to Jun-ichiro itojun Hagino <itojun@iijlab.net>
for insisting on retaining security for multi-byte locales.
If you experience any problems with these changes, please send me email
describing the problem and how to repeat it. I'd rather try to fix the
problem than have this change reverted. Thanks!
daemon is a bad idea, (2) there's no standard in 8bit finger, (3) there's no
guarantee that finger/fingerd uses the same locale, (4) existing finger client
could scream. see tech-userlevel.
valid for output. If something bad gets printed, either the locale
settings for the user (or output terminal) are wrong, or the LC_CTYPE
definitions on the system are invalid.
-o (the reverse of this, also the default)
- use vis(3) in vputc() instead of handcrufted function (from OpenBSD).
- move gecos expansion into expandusername() (a la sendmail's buildfname).
A generic version of this last bit in libutil would be useful...
- cleanup the code, fix prototypes, etc.
needed a finger on that platform which grokked the office/phone # GCOS
info), I decided to put mail status in (as the solaris version has
that).
The attached patch adds:
- manual page typos fixed: finger doesn't scan .forward, contrary to
what the man page says (and really shouldn't either, IMHO - that's
what telnet host SMTP & VRFY are for :)
- added a mail check (printed between login info and the project).
three different messages possible:
- if you have no mail:
No Mail.
- if you have mail, but there's no unread mail:
Mail last read DDD MMM ## HH:MM (TZ)
- if you have new mail:
New mail received DDD MMM ## HH:MM (TZ)
Unread since DDD MMM ## HH:MM (TZ)
- fixed the manual page.
