Bug #2415
closed
setlocale() for unknown locales
Description
The return value of setlocale() for LC_ALL deviates from implementations
found in FreeBSD, NetBSD, GNU libc and OpenSolaris. Other implementations
return NULL for unknown locales and the category LC_ALL, where instead
DragonflyBSD isresponding with the internal value list.
Thus an environment variable LC_ALL=fake produces
- setlocale(LC_ALL, "");
C/C/fake/fake/fake/C
- setlocale(LC_CTYPE, "");
(null)
The LC_ALL category is hiding the erroneous effect from the
invoking program, whereas the other categories are correctly
reporting their failures.

Hi,
Not sure if I've understood. In the case you pass the "locale" string to setlocale(3):
$ uname -a
DragonFly hammer.df.com 3.6-RELEASE DragonFly v3.6.0-RELEASE #8: Fri Nov 22 13:22:00 PST 2013 root@pkgbox64.dragonflybsd.org:/usr/obj/build/home/justin/src/sys/X86_64_GENERIC x86_64
$ ./t_locale
setlocale(LC_ALL, "es_ES.UTF-8")=es_ES.UTF-8
setlocale(LC_ALL, "en_EN.UTF-8")=(null)
setlocale(LC_ALL, "fake")=(null)
setlocale(LC_ALL, NULL)=es_ES.UTF-8
$ uname -a
DragonFly hammer.df.com 3.7-DEVELOPMENT DragonFly v3.7.1.1227.g566f1-DEVELOPMENT #1: Thu May 22 19:25:43 CEST 2014 root@:/usr/obj/usr/src/sys/X86_64_GENERIC x86_64
$ ./t_locale1
setlocale(LC_ALL, "es_ES.UTF-8")=es_ES.UTF-8
setlocale(LC_ALL, "en_EN.UTF-8")=(null)
setlocale(LC_ALL, "fake")=(null)
setlocale(LC_ALL, NULL)=es_ES.UTF-8
root@testfbsd:/root # uname -a
FreeBSD testfbsd 9.1-RELEASE-p10 FreeBSD 9.1-RELEASE-p10 #0: Sun Jan 12 20:11:23 UTC 2014 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64
root@testfbsd:/root # cc t_locale.c -o t_locale
root@testfbsd:/root # ./t_locale
setlocale(LC_ALL, "es_ES.UTF-8")=es_ES.UTF-8
setlocale(LC_ALL, "en_EN.UTF-8")=(null)
setlocale(LC_ALL, "fake")=(null)
setlocale(LC_ALL, NULL)=es_ES.UTF-8
In the case of using "" as locale:
DFly:
$ ./t_locale1
setlocale(LC_ALL, "")=(null)
$ echo $LC_ALL
fake
FreBSD 9.1:
root@testfbsd:/root # ./t_locale
setlocale(LC_ALL, "")=(null)
root@testfbsd:/root # echo $LC_ALL
fake
I hope I'm not misunderstanding what you just said.
Best regards,

Your reading of my message was correct, but with a probability close to certainty
this issue was inadvertedly amended in commit 0d5acd74 by John Marino, whose commit
touched also the file "lib/libc/locale/setlocale.c".
For reference, the behaviour of 3.4 and 3.9:
$ uname -v
DragonFly v3.9.0.33.g96b40-DEVELOPMENT ...
setlocale(LC_ALL, "fake") = NULL
and identically for LC_COLLATE, LC_CTYPE, LC_MESSAGES, LC_MONETARY,
LC_NUMERIC and LC_TIME.
$ uname -v
DragonFly v3.4.3-RELEASE ...
setlocale(LC_ALL, "fake") = "C/C/fake/fake/fake/C"
setlocale(LC_MONETARY, "fake") = "fake"
setlocale(LC_NUMERIC, "fake") = "fake"
setlocale(LC_TIME, "fake") = "fake"
but the correct value NULL is passed for LC_COLLATE, LC_CTYPE, LC_MESSAGES.
I must conclude that the issue #2415 can be closed for the current
development branch.
Best regards,
Mats Erik Andersson
