[Pulp-list] Timestamp question



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

When performing a CDS sync, we write out two CDS events to the mongo DB,
"sync_started" and "sync_finished", with the actual sync occuring in
between. Then when you get the CDS event history, they are sorted by
timestamp (default to descending order).

I have a few unit tests that check to make sure those are present. The
tests where sync throws an error are sporadically failing.

- From what I can tell, sometimes the history events are being returned
with the "sync_finished" occuring before the "sync_started" in the event
list.  I'm not entirely sure why.

When the event is created to be saved, it's setting the timestamp to
datetime.datetime.now(). I'm wondering if that's not precise enough to
differentiate between two events created in rapid succession, as would
occur if that sync call immediately errors out.

Is there something better I should be using for the value for the timestamp?

I added in a secondary sort by ID. The inserts are done with safe=True,
so they should get IDs that will properly reflect their order. I'm
hoping that clears it up. If hudson still randomly complains about
failures and the error comes from test_cds_api.py, let me know because
it's likely this issue.
