Benjamin Bannier commented on MESOS-7016:
-----------------------------------------
Linking MESOS-7318 which is related in the sense that test expectations might
also fail when tests are run in e.g., a virtual machine which is for some
reason suspended by the host.
> Make default AWAIT_* duration configurable

> Key: MESOS-7016
> URL: https://issues.apache.org/jira/browse/MESOS-7016
> Project: Mesos
> Issue Type: Improvement
> Components: libprocess, test
> Reporter: Benjamin Bannier
>
> libprocess defines a number of helpers {{AWAIT_*}} to wait for a
> {{process::Future}} reaching terminal states. These helpers are used in tests.
> Currently the default duration to wait before triggering an assertion failure
> is 15s. This value was chosen as a compromise between failing fast on likely
> fast developer machines, but also allowing enough time for tests to pass in
> high-contention environments (e.g., overbooked CI machines).
> If a machine is more overloaded than expected, {{Futures}} might take longer
> to reach the desired state, and tests could fail. Ultimately we should
> consider running tests with paused clock to eliminate this source of test
> flakiness, see MESOS-4101, but as an intermediate measure we should make the
> default timeout duration configurable.
> A simple approach might be to expose a build variable allowing users to set
> at configure/cmake time a desired timeout duration for the setup they are
> building for. This would allow us to define longer timeouts in the CI build
> scripts, while keeping default timeouts as short as possible.
