Philip O'Toole 42b4a0b8bf string return is totally unused 2015-07-22 02:55:13 -07:00
Philip O'Toole 45dcf9960c Optimize the very inner loop of cursor iteration 
This change moves tracking of next timestamp and values to simple
slices, as performance measurement showed that Peek() on TagSet cursors
was a huge performance drain. There is much more that can be done here,
but with this in place query performance has been restored to 0.9.1
levels.

This change also uses -1 to indicate that no value is available for a
given timestamp.

Jason Wilder d0cc98356b Fix error calling MarshalJSON for type *influxdb.Result: json: unsupported value: NaN 
If the MapMean did not have any values in the iterator, it would return
and empty meanMapOutput().  ReduceMean would in turn divider the results
by an unitialized float64 producing a NaN.  NaN is not serializable to JSON
by default.
