(Updated Aug. 1, 2019, 11:03 a.m.) Review request for mesos and Andrei Sekretenko. Changes ------- Tweak existing comment as suggested by asekretenko offline Repository: mesos Description ------- The code intends to construct a seconds value too 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.
