Description From Peter Lane 2006-06-14 13:09:24

The PBS adapter module is setting LD_LIBRARY_PATH and it's cousin library env
vars to nothing (i.e. "LD_LIBRARY_PATH=;") if no libraryPath elements were
specified in the job description. This is causing problems with the SoftEnv
extensions because it overrides any values SoftEnv would have set for these env
vars.

I propose that these library vars should simply not be set if there are no
occurances of the libraryPath elements in the job description. That would still
allow the user to override SoftEnv with explicity library paths if so desired.
Fixes should be added to HEAD, globus_4_0_branch, and globus_4_0_community.

What are the semantics supposed to be for the various ways one can set the
library-path: environment, libraryPath, and softEnv? What should be done if
more than one is present (override, append) and in what order ought they be
evaluated?

I would say the order of priority would be SoftEnv, environment, libraryPath
since it goes from least explicit to most explicit. Nothing needs to be done to
check SoftEnv since it doesn't actually set anything explicitly in the adapter
module.

committed a fix to the pbs job manager in 4.0 branch, 4.2 branch and trunk
