[ovs-dev] [PATCH ovn v4.1 4/7] tests: Eliminate most "sleep" calls.
Ben Pfaff
blp at ovn.org
Wed Nov 11 01:24:51 UTC 2020
Many of these could be replaced by "ovn-nbctl sync". Some weren't
really needed at all because they were adjacent to something that itself
called sync or otherwise used --wait. Some were more appropriately
done with explicit waits for what was really needed.
I left some "sleep"s. Some were because they were "negative" sleeps:
they were giving time for something to happen that should *not* happen
(in other words, if you wait for it to happen, you'll wait forever,
unless there's a bug). Some were because I didn't know how to properly
wait for what they were waiting for, or because I didn't understand
the circumstances deeply enough.
