Package: bash
Version: 3.1-4
Severity: important
"unset LANG" doesn't change the locale of the current bash.
I think this is an omission. This leads to the following
inconsitency:
$ env | egrep LANG
LANG=en_US
LANGUAGE=en_US:en_GB:en
$ echo [D-Y]*
m M
$ unset LANG LANGUAGE
$ echo [D-Y]*
m M
$ /bin/bash
$ env | egrep LANG
$ echo [D-P]*
M
$
That is, even in the absense of the LANG env. var.,
[D-Y] matches both lower and upper cases in the parent bash,
but not so, in the child. Since "export LANG=C" changes
the locale of the current bash, so should "unset LANG".
The experiment above was done without any dot-files in my home
directory. In particular, I didn't have
~/.bash, ~/.bash_profile, or ~/.profile
I'm attaching a typescript obtained as
script -c 'ltrace -e setlocale bash'
(My mistypes were edited out from the script.)
Hope this helps,
Ryo
