Description

webperf: log per-user-agent Navigation Timing data

  • Parse user-agent strings using a custom set of regular expressions, because the set of browsers which implement Navigation Timing is a small subset of the set of browsers that user-agent parsing libraries handle. The regular expressions in this patch were tested against a log of user-agent strings from NavigationTiming events.
  • Drop '_with_zero' metrics, added for T104902.

Data will be available under the metric hierarchy
frontend.navtiming.by_platform.*.
