26ba25
219 has two issues that may lead to sporadic failure, both of which are
26ba25
the result of issuing query-jobs too early after a job has been
26ba25
modified.  This can then lead to different results based on whether the
26ba25
modification has taken effect already or not.
26ba25
26ba25
First, query-jobs is issued right after the job has been created.
26ba25
Besides its current progress possibly being in any random state (which
26ba25
has already been taken care of), its total progress too is basically
26ba25
arbitrary, because the job may not yet have been able to determine it.
26ba25
This patch addresses this by just filtering the total progress, like
26ba25
what has been done for the current progress already.  However, for more
26ba25
clarity, the filtering is changed to replace the values by a string
26ba25
'FILTERED' instead of deleting them.
26ba25
26ba25
Secondly, query-jobs is issued right after a job has been resumed.  The
26ba25
job may or may not yet have had the time to actually perform any I/O,
26ba25
and thus its current progress may or may not have advanced.  To make
26ba25
sure it has indeed advanced (which is what the reference output already
26ba25
assumes), keep querying it until it has.
