Perhaps you can query the status of job using the correlation id
(taking the examples from ovirt-system-tests):
dead_snap1_params = types.Snapshot(
description=SNAPSHOT_DESC_1,
persist_memorystate=False,
disk_attachments=[
types.DiskAttachment(
disk=types.Disk(
id=disk.id [5]
)
)
]
)
correlation_id = uuid.uuid4()
vm1_snapshots_service.add(dead_snap1_params,
query={'correlation_id':
correlation_id})
testlib.assert_true_within_long(
lambda:
test_utils.all_jobs_finished(engine, correlation_id)
)
I tried this approach but with the snapshot deletion task instead of
creating one.
customuuid = uuid4()
snaps_service.service(newsnap.id).remove(query={'correlation_id':
customuuid})
However, when this task is run, I see no task with this correlation_id.
Moreover, I cannot find a correlation_id field in the job object.
In [40]: job
Out[40]: <ovirtsdk4.types.Job at 0x7f30c9312a10>
In [41]: job.
job.auto_cleared job.description job.external job.id
job.name job.start_time job.steps
job.comment job.end_time job.href job.last_updated
job.owner job.status
The 'id' field doesn't correspond to the correlation_id generated above.
All jobs finished checks that jobs with correlation_id have
finished,
it is implemented like this[2]:
def all_jobs_finished(engine, correlation_id):
try:
jobs = engine.jobs_service().list(
search='correlation_id=%s' % correlation_id
)
except:
jobs = engine.jobs_service().list()
return all(job.status != types.JobStatus.STARTED for job in
jobs)
You can instead do something like this:
jobs = engine.jobs_service().list(
search='correlation_id=%s' % correlation_id
)
This won't work either, it returns an exception claiming this:
TypeError: list() got an unexpected keyword argument 'search'
Any further hints with this?
Thanks
