[Toaster] [PATCH 1/2] toaster: time data for tasks differ from buildstats

Tue Mar 11 08:15:06 PDT 2014


The BuildInfoHelper class was measuring separately the time for a build.
This was causing many difference in the time measured by buildstats class and
the time measured here. The main problem is toaster does database operations
which delay the arrival of events.

The simplest solution, which is implemented in this fix, is to keep the time
of creation for every BaseTask event and calculate the duration by making a
difference between the creation time of TaskSucceeded and TaskStarted.
