getent group fails

getent group fails

[Denis Excoffier]

Hello,

I'm under x86, with no /etc/nsswitch.conf, and my /etc/passwd and group
files with 1 line each (me and 'Domain Users'). The command
'getent group' seems to loop forever on the 'Users' group:

% /usr/bin/getent group
Domain Users:S-1-5-21-878717028-1334384809-310601177-513:10513:
+Users:S-1-5-32-545:545:
...
+Users:S-1-5-32-545:545:
^C
%

'getent passwd' seems ok (9 lines): my line and 8 lines beginning
with '+’.

I tried several snapshots (including 20140507), and this bahaviour
was already present in snapshot 20140410 (the first one where the
"Corinna's prize-winning passwd/group rewrite" was reintroduced). It
was not present in snapshot 20140305.

Regards,

Denis Excoffier.

Thanks for the report.  I made a dumb Copy/paste error.  This should
be fixed in the today's snapshot from http://cygwin.com/snapshots/


Thanks,
Corinna

Indeed, it is working now.

Also, i have noticed that 'getent group' produces this line:

+Utilisateurs authentifiés:S-1-5-11:11:
 (with \303\251 meaning é, like under UTF-8)

while 'getent passwd' produces (among other lines):

+SERVICE RÉSEAU:*:20:20:,S-1-5-20:/:/sbin/nologin
  (with \311 meaning É, like under ISO-Latin)

This is with LC_CTYPE=fr_FR, no /etc/nsswitch.conf, /etc/passwd
and /etc/group with only one line each, domain member with currently no
network connected, under Cygwin 32bits 'Just Me', installed on top of
XP SP3 32bits [french only], with snapshot '20140508 19:51:25’,
and all packages up-to-date.

If i setenv LC_CTYPE C, or unsetenv LC_CTYPE, i also get UTF-8 for
'getent passwd' (ie for both).

What bothers me is that under LC_CTYPE=fr_FR (or fr_FR@euro), the
getent output is not consistent.

Denis Excoffier.

I can't explain that.  In both cases, getent calls setlocale(LC_ALL, "").
In both cases, the account information comes as UTF-16 string from
the OS and is converted to multibyte in Cygwin.

The only (vague) idea I have is that this may be a result of caching.
If the first account ("authenticated users") has been fetched while
LANG was still set to "C" or "C.UTF-8", it would explain this
discrepancy.

Which shows that using non UTF-8 locales is not such a good idea.  There
is a chicken-egg problem.  Early initialization always uses UTF-8 for
hopefully obvious reasons.  Using UTF-8 in all multibyte scenarios is
really the way to go in future.

Do you by chance set any of the LC_* variables separately anywhere?

I've seen a problem with locales in UTF-8 vs. singlebyte terminal encodings,
but it was supposedly fixed.
But I only set LANG=, and let the subsystem do the magic.
