Hello Alexey Serbin, Yingchun Lai, Kudu Jenkins, Adar Dembo,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/14979
to look at the new patch set (#2).
Change subject: tablet: detach metrics first in destructor
......................................................................
tablet: detach metrics first in destructor
Previously the FunctionGaugeDetacher in a Tablet could be destructed
after some of the state in the Tablet had already been destructed.
Specifically, the metrics would be detached after destructing
'last_rw_time_lock_' et al. This led to some TSAN warnings[1].
Without this patch, RaftConsensusNumLeadersMetricTest
TestNumLeadersMetric, which deletes tablets and then immediately fetches
metrics, would fail 29/1000 times in TSAN mode. With it, it only failed
7/1000, those due to an unrelated timeout (not addressed in this patch).
I went ahead and updated other misordered instances of
FunctionGaugeDetachers. As far as I can tell, there aren't any other
affected tests.
