Ramkumar Aiyengar reopened SOLR-6275:
-------------------------------------
Reopening this to resolve some Jenkins failures with the MacOSX..
[~thetaphi] pointed me to
http://mail.openjdk.java.net/pipermail/hotspot-dev/2013-May/009496.html which
talks about MacOSX using wall time instead (gettimeofday) -- which would
certainly fail this test (and is in some sense validation of why this issue
exists! :) )
We have two approaches here..
- Disable the test for {{nanoTime}} altogether
- Disable it just for MacOSX
I haven't included reverting the change as it doesn't make things any better,
the test failure is on a platform which is a no-op as far as this change is
concerned anyway, and there haven't been other failures..
> Improve accuracy of QTime reporting

> Currently, {{QTime}} uses {{currentTimeMillis}} instead of {{nano Time}} and
> hence is not suitable for time measurements. Further, it is really started
> after all the dispatch logic in {{SolrDispatchFilter}} (same with the top
> level timing reported by {{debug=timing}}) which may or may not be expensive,
> and hence may not fully represent the time taken by the search. This is to
> remedy both cases.
