Bug#645221: tomcat6: Tomcat6 initscript influenced by user's environment variables

[Nicolas Pichon]

Package: tomcat6
Version: 6.0.32-6
Severity: normal
Tags: l10n


Hi,

I use Tomcat6 on several machines running Debian Squeeze and Sid. Some of them are servers using locale en_GB.UTF-8, while my PC is using fr_FR.UTF-8. When I'm connecting on these servers, SSH forwards some environment variables, including LC_ALL.

Here is my PC's locale :

LANG=fr_FR.UTF-8
LANGUAGE=fr_FR.UTF-8
LC_CTYPE="fr_FR.UTF-8"
LC_NUMERIC="fr_FR.UTF-8"
LC_TIME="fr_FR.UTF-8"
LC_COLLATE="fr_FR.UTF-8"
LC_MONETARY="fr_FR.UTF-8"
LC_MESSAGES="fr_FR.UTF-8"
LC_PAPER="fr_FR.UTF-8"
LC_NAME="fr_FR.UTF-8"
LC_ADDRESS="fr_FR.UTF-8"
LC_TELEPHONE="fr_FR.UTF-8"
LC_MEASUREMENT="fr_FR.UTF-8"
LC_IDENTIFICATION="fr_FR.UTF-8"
LC_ALL=fr_FR.UTF-8


And here is the locale on the server when I'm connected to by SSH :

LANG=en_GB.UTF-8
LANGUAGE=en_GB:en
LC_CTYPE="fr_FR.UTF-8"
LC_NUMERIC="fr_FR.UTF-8"
LC_TIME="fr_FR.UTF-8"
LC_COLLATE="fr_FR.UTF-8"
LC_MONETARY="fr_FR.UTF-8"
LC_MESSAGES="fr_FR.UTF-8"
LC_PAPER="fr_FR.UTF-8"
LC_NAME="fr_FR.UTF-8"
LC_ADDRESS="fr_FR.UTF-8"
LC_TELEPHONE="fr_FR.UTF-8"
LC_MEASUREMENT="fr_FR.UTF-8"
LC_IDENTIFICATION="fr_FR.UTF-8"
LC_ALL=fr_FR.UTF-8



This is because Debian's openssh-client package has by default "SendEnv LANG LC_*" in /etc/ssh/ssh_config (which is not the case upstream according to the ssh_config(5) manpage)


After a server restart; if I run a test JSP script which outputs the day of week, I get "Thursday" :

SimpleDateFormat day_of_week = new SimpleDateFormat("EEEEEEEEE");
out.print(day_of_week.format(new java.util.Date()));


If I do a "/etc/init.d/tomcat6 restart", The same page gives "jeudi".

I added a line "unset LC_ALL" in /etc/default/tomcat6 and restarted Tomcat, and the test script gives now "Thursday".


Init scripts should not be influenced by user's environment, and restarting Tomcat by a user should not give a behaviour different to when Tomcat has been started on system boot.

The fix would be to unset LC_ALL variable in the init script provided by the package.

Nicolas Pichon.
