Thanks for the info. Beware that using the LANGUAGE envvar like that takes advantage of a glibc extension, and hence is not portable. Knowing this, I've added "LANGUAGE" to the list of envvars that coreutils unsets when running its test suite. (for many Perl scripts it was already handled in individual scripts, but this change also protects shell scripts, none of which guarded against this) From 837924c5a3554f0f875625ec08c50de3708d8ae9 Mon Sep 17 00:00:00 2001 From: Jim Meyering <[email protected]> Date: Wed, 3 Mar 2010 20:55:27 +0100 Subject: [PATCH] tests: don't let the LANGUAGE envvar perturb tests * tests/envvar-check (vars): Add LANGUAGE to the list of envvars to unset, if possible. At least in glibc (as an extension to POSIX), its value actually trumps LC_ALL when the default locale is not C: $ LC_ALL=C LANGUAGE=fr_FR.UTF-8 /bin/cat no-such /bin/cat: no-such: No such file or directory $ LC_ALL=es_ES LANGUAGE=fr_FR.UTF-8 /bin/cat no-such /bin/cat: no-such: Aucun fichier ou dossier de ce type Prompted by a report from Mads Kiilerich. --- tests/envvar-check | 1 + 1 files changed, 1 insertions(+), 0 deletions(-) diff --git a/tests/envvar-check b/tests/envvar-check index 65fda9b..e31b941 100644 --- a/tests/envvar-check +++ b/tests/envvar-check @@ -31,6 +31,7 @@ vars=' COLUMNS DF_BLOCK_SIZE DU_BLOCK_SIZE + LANGUAGE LS_BLOCK_SIZE LS_COLORS POSIXLY_CORRECT -- 1.7.0.1.464.g0adc7 -- livecd mailing list [email protected] https://admin.fedoraproject.org/mailman/listinfo/livecd
