Upstream-Status:Inappropriate [debian patch] From: Niko Tyni Subject: Squelch locale warnings in Debian package maintainer scripts Bug-Debian: http://bugs.debian.org/508764 The system locales are rather frequently out of sync with the C library during package upgrades, causing a huge amount of useless Perl locale warnings. Squelch them when running package maintainer scripts, detected by the DPKG_RUNNING_VERSION environment variable. Any real locale problem will show up after the system upgrade too, and the warning will be triggered normally again at that point. --- locale.c | 4 ++++ pod/perllocale.pod | 8 ++++++++ 2 files changed, 12 insertions(+), 0 deletions(-) diff --git a/locale.c b/locale.c index 16ccce8..2592b3c 100644 --- a/locale.c +++ b/locale.c @@ -359,6 +359,10 @@ Perl_init_i18nl10n(pTHX_ int printwarn) char *p; const bool locwarn = (printwarn > 1 || (printwarn && + + /* Debian specific change - see http://bugs.debian.org/508764 */ + (!PerlEnv_getenv("DPKG_RUNNING_VERSION")) && + (!(p = PerlEnv_getenv("PERL_BADLANG")) || atoi(p)))); if (locwarn) { diff --git a/pod/perllocale.pod b/pod/perllocale.pod index 0dbabe7..60b7bab 100644 --- a/pod/perllocale.pod +++ b/pod/perllocale.pod @@ -844,6 +844,14 @@ B: PERL_BADLANG only gives you a way to hide the warning message.
