Sudo ruby loosing environment?

Ruby

My Ruby installation is from the Ubuntu package repository. Yesterday,
I upgraded my system to Heron and since then one of my Ruby scripts
stopped working. I traced the problem to this:

$ ruby -e"p ENV[‘ROLL_PATH’]"
“/home/trans/Company/TigerOps/programs”

$ sudo ruby -e"p ENV[‘ROLL_PATH’]"
nil

At first I though it might have something to do with sudo itself, but:

$ echo $ROLL_PATH
/home/trans/Company/TigerOps/programs

$ sudo echo $ROLL_PATH
/home/trans/Company/TigerOps/programs

So that’s not it. Anyone have any idea what’s going on?

My current version of Ruby is now:

$ ruby -v
ruby 1.8.6 (2007-09-24 patchlevel 111) [x86_64-linux]

Thanks,
T.

Yes, it’s sudo. Your test is flawed.

$ echo $ROLL_PATH
/home/trans/Company/TigerOps/programs

$ sudo echo $ROLL_PATH
/home/trans/Company/TigerOps/programs

$ROLL_PATH is interpreted by the shell before sudo is ever invoked.

This is unrelated to Ruby or Ubuntu. This is how sudo works. Read the
sudoers man page, looking for env_keep. You will need to edit the
/etc/sudoers file (with visudo, not directly).

Ok. That makes sense. Though I don’t yet understand what changed --it
was working fine before the dist-upgrade.
