Some changes on the same class appears that they could be consolidated but it wasn't easy to do so and I think there is merit in keeping the history.
## Bug Fix 1. Fixed Duration's stream insertion operator so that the output string does not have trailing zeros after the decimal point. (libstout): https://reviews.apache.org/r/11134 ## Clock::now() returns "double -> Duration" 2. Added a default constructor for Seconds for Clock::now() to return Seconds. (libstout): https://reviews.apache.org/r/11136 3. Updated Clock::now() and Clock::now(ProcessBase*) to return a "Seconds". (libprocess): https://reviews.apache.org/r/11137 4. Updates due to Clock::now() and Clock::now(ProcessBase*) now returning a "Seconds": https://reviews.apache.org/r/11138 ## Storing integer in Duration - Per our initial discussion we decided to keep the constructors using doubles because some third-party APIs still use them. 5. Changed Duration to use int64_t to store the value in nanoseconds for better precision. (libstout): https://reviews.apache.org/r/11139 6. Fix due to Seconds can no longer hold DBL_MAX correctly. (libprocess): https://reviews.apache.org/r/11140 ## Time 7. Added a Time class as a new abstraction that works with Duration for various time related calculations. (libprocess): https://reviews.apache.org/r/11142 8. Replaced usage of "Seconds" and "Duration" that represents time with the new "Time". (libprocess): https://reviews.apache.org/r/11143 ## Duration adopts integer constructors - We now decided to get rid of "double" constructors. For cases where a Duration needs to be constructed from a "double", a Try method is added. 9. Changed Duration to 1) use integers in constructors; 2) include overloaded multiplication & division operators. (libstout): https://reviews.apache.org/r/11145 10. Fixes in libprocess due to the new Duration API. (libprocess): https://reviews.apache.org/r/11146 11. Fixes due to the new Duration API. (Mesos): https://reviews.apache.org/r/11147 ## More Refactoring on eliminating time in the "double" type. 12. Changed various *time* variables to use the "Time" type instead of "double": https://reviews.apache.org/r/11148 Yan -- Jiang Yan Xu <[email protected]> @xujyan <http://twitter.com/xujyan>
