This seems to be because the $_MODULEBEGINENV_ environment variable is not reset when we change to a new user. The same kind of thing happens if you login as a normal user with a $HOME on a node with an NFS filesystem that has no root privlidges, and you "su" to root -- root cannot write to the user's $HOME/.modulesbeginenv. It seems that there are several variables that should probably be reset/unset when we change to a new user. So in addition to $MODULE_OSCAR, do we also need a $MODULE_OSCAR_USER that we maintain the username of the current user, and if whoami returns a different string than what is in $MODULE_OSCAR_USER, then we reset all the module env vars and re-do all the setup? Something along these lines is worth looking into. ---------------------------------------------------------------------- >Comment By: Jeff Squyres (jsquyres) Date: 2002-05-24 00:32 Message: Logged In: YES user_id=11722 Oops -- this was fixed, not a duplicate. ---------------------------------------------------------------------- Comment By: Jeff Squyres (jsquyres) Date: 2002-05-23 22:21 Message: Logged In: YES user_id=11722 Fixed in CVS. Now, if the shell or the user changes, the profile.d/00-modules.* shell script will detect this and force the modules package to do a hard reset by unsetting all the modules-related environment variables. ---------------------------------------------------------------------- You can respond by visiting: http://sourceforge.net/tracker/?func=detail&atid=465044&aid=559634&group_id=51915 |
