progressReportIntervalMilliseconds (old
ProgressReportIntervalMilliseconds) is accessed by multiple goroutines
and it is reported as race.
For avoiding this report, this commit wraps the variable with
functions. They access the variable with atomic operations so the race
won't be reported.
Fix https://github.com/coreos/etcd/issues/4730.
Previously we put keys async and there might be a race when
the watch triggers before the put receives the response. When that
happens, put might fails to get the response since we shutdown the server
when watch triggers.
This sets Created and Cancel true in pb.WatchResponse
when it has received wrong start revision instead of
panic. So that clientv3 can set 'Canceled' in WatchResponse
as well.
Fix https://github.com/coreos/etcd/issues/4610.
