Jeremy White ATS Issues

[dawson6]

so ran into a couple things trying to get that new flux adapter working.

first is just a note on flux shenanigans in case you get questions: if in a virtualenv you do have to have cffi and pyyaml installed for import flux to work -> they are in the base python installs on the clusters and thus it worked for your example just fine, but they won't be if you spawn a clean virtual environment from those python installs. And boy were those stack traces pointing to flux's python unhelpful, lol

second, i think i found a bug in ats in the latest branch when i pulled in changes from python3->7.0.111 to get the new adapter. This new ats code parser appears to choke on our ats files: python3...release/7.0.111#diff-688de384e3480973c6f9e0c6a4ba14267b4ddcc5091a572d33d3ddc53693f73cL256

the sample that seems to crash it is a simple test collector:

import os
fnames=os.listdir('.')
for fname in fnames:

dies in here before it can do anything -> looks like it's execing incomplete chunks or something? i dunno, as i've not done much ast hacking before
