Review request for mesos and Andrei Sekretenko.
Repository: mesos
Description
-------
The code intends to construct a seconds value to large to fit into the
internal representation in nanoseconds, but since the `long` value was
passed to a function expecting a `double` the value will implicitly be
converted. As the `long` value is large, `double` is not able to
represent all possible `long` values which can lead to lossy
conversions.
This is exactly what happened here. Recent clang has a warning to catch
such issues at compile time if possible,
```
../src/tests/master_tests.cpp:7194:34: warning: implicit conversion from
'long' to 'double' changes value from 99999999999999999 to 1.0E+17
[-Wimplicit-int-float-conversion]
framework.set_failover_timeout(99999999999999999);
~~~~~~~~~~~~~~~~~~~~ ^~~~~~~~~~~~~~~~~
```
This patch changes the value to `1e+17` (a `double` value) which removes
the lossy conversion, and still accomplishes what the test required.
