Anand Mazumdar commented on MESOS-5886: --------------------------------------- [~abudnik] Can you find a shepherd for this? I am retargeting this for 1.5.0. > FUTURE_DISPATCH may react on irrelevant dispatch. > ------------------------------------------------- > > Key: MESOS-5886 > URL: https://issues.apache.org/jira/browse/MESOS-5886 > Project: Mesos > Issue Type: Bug > Affects Versions: 1.1.2, 1.2.1, 1.3.0, 1.4.0 > Reporter: Alexander Rukletsov > Assignee: Andrei Budnik > Labels: mesosphere, tech-debt, tech-debt-test > > [{{FUTURE_DISPATCH}}|https://github.com/apache/mesos/blob/e8ebbe5fe4189ef7ab046da2276a6abee41deeb2/3rdparty/libprocess/include/process/gmock.hpp#L50] > uses > [{{DispatchMatcher}}|https://github.com/apache/mesos/blob/e8ebbe5fe4189ef7ab046da2276a6abee41deeb2/3rdparty/libprocess/include/process/gmock.hpp#L350] > to figure out whether a processed {{DispatchEvent}} is the same the user is > waiting for.
