Summary
This PR attempts to handle the results file failures by separating concerns.
Load the results file without changing directories. We are pretty consistently seeing "No file named
results_<whatever>.pklz
, which at the minimum is uninformative. There's no reason not to know the full path of the file when we try to open it.Perform
pickle.loads
on the file contents as a single-linewith indirectory
context block.All other operations are directory independent and file-lock independent.
Alternative to #3047.
Sorry to preempt that process, but we're seeing this a lot, and I don't really know how to help move that one along. I'm going to use this branch to see if we can resolve these issues that are popping up a lot in the fMRIPrep tests.
