GLExec Wrap and Unwrap environment variables] describes how you can wrap environment variables in such a way that they don't get wipe and unwrap them (safely) in the target account (pilot job payload) process.
Where to find packages and sources
We provide a new packages named glexec-wrapper-scripts (at the moment primarily) through the Etics system.
The sources can be found in our SVN repository.
gLExec wrapper scripts: glexec_wrapenv.pl and glexec_unwrapenv.pl)
Helper script to restore the environment variables previously wrapped into the environment variable GLEXEC_ENV using the glexec_wrapenv.pl script.
Intended usage:
export GLEXEC_ENV=`glexec_wrapenv.pl` /opt/glite/sbin/glexec glexec_unwrapenv.pl -- <YOUR-COMMAND>
By default the following environment variables are NOT unwrapped:
- HOME
- LOGNAME
- USER
- X509_USER_PROXY
- _ (yes that's '_' !)
A user can add more env vars to be excluded using either
--exclude=A --exclude=B
or
--exclude=A,B,...
Example 1:
export GLEXEC_ENV=`glexec_wrapenv.pl --exclude=MYVAR` /opt/glite/sbin/glexec glexec_unwrapenv.pl -- <YOUR-COMMAND>
Example 2:
export GLEXEC_ENV=`glexec_wrapenv.pl` /opt/glite/sbin/glexec glexec_unwrapenv.pl --exclude=MYVAR -- <YOUR-COMMAND>
Example 3:
export GLEXEC_ENV=`glexec_wrapenv.pl --exclude=MYVAR` /opt/glite/sbin/glexec glexec_unwrapenv.pl -- <YOUR-COMMAND>
