The XFilesFactor that was being passed to the create method was being ignored previously. Now it isn't. Signed-off-by: ciaranj <ciaranj@gmail.com>
Previously calls to updateMany would ultimately have their data discarded, as concat does not mutate the existing arrays but returns a new one, the python-ported algorithm doesn't quite apply. Signed-off-by: ciaranj <ciaranj@gmail.com>
This change may be un-acceptable :(. If Hoard.js is used within the same process as statsd (as for example a back-end) then it is possible that hoard will refuse updates from statsD's flush event as the timestamp that statsd generates will appear to be from the future. This is because Hoard.js was using: parseInt( new Date().getTime() / 1000 ) But statsd is using : Math.round( new Date().getTime() / 1000 ) To get their idea of 'now'. Most of the time this will be ok, but if a the result of the division contains a fractional part greater than or equal to .5 then statsd will round-up to the next nearest integer value but Hoard was truncating (discarding?) the fractional part, meaning it would be (as far as it was concerned) timestamps from the future when update was called sufficiently quickly after the flush.

Much like commit 0cc664 in the python whisper project, this commit introduces support for specifying the aggregation type (one of 'sum', 'max', 'min', 'last' or 'average') when propagating values into the lower precision archives. This commit also bumps the package number as it introduces a breaking change to the create interface by making the xFilesFactor and new aggregationMethod arguments optional (defaulting to 0.5 and average respectively). Following semver.org recommendations that means a bump to the middle value :) Signed-off-by: ciaranj <ciaranj@gmail.com>

Be aware of @3c8b006 that might be contentious! |

3c8b006 is "contentious" but needed for compatibility. I like it. Let's get it merged! |

Just so you're aware, I've stopped working on this library, and moved over to https://github.com/ciaranj/ceres/tree/nodejs_port might be of use :) |

Based on top of the work done by @cwholt further fixes and an implementation of the aggregation method support, so now when aggregating to lower precision archives 'max, min, sum, last and average' can be used instead of just always averaging (the same as python's whisper)
