Matt T. Proud a3f1d81e24 Publicize a few storage components for curation.
This commit introduces the publicization of Stop and other
components, which the compaction curator shall take advantage
of.

Matt T. Proud db4ffbb262 Wrap dto.SampleKey with business logic type.
The curator work can be done easier if dto.SampleKey is no longer
directly accessed but rather has a higher level type around it that
captures a certain modicum of business logic.  This doesn't look
terribly interesting today, but it will get more so.

Matt T. Proud 092c7bd88e Stochastic test support plural SampleValueSeries.
After SampleValue was refactored into SampleValueSeries, which
involves plural values under a common super key, the stochastic
test was never refreshed to reflect this reality.  We had other
tests that validated the functionality, but this one was
insufficently forward-ported.

Julius Volz 99dcbe0f94 Integrate memory and disk layers in view rendering. 2013-04-19 16:01:27 +02:00
Julius Volz 63625bd244 Make view use memory persistence, remove obsolete code.
This makes the memory persistence the backing store for views and
adjusts the MetricPersistence interface accordingly. It also removes
unused Get* method implementations from the LevelDB persistence so they
don't need to be adapted to the new interface. In the future, we should
rethink these interfaces.

All staleness and interpolation handling is now removed from the storage
layer and will be handled only by the query layer in the future.

Matt T. Proud a55602df4a Validate diskFrontier domain for series candidate.
It is the case with the benchmark tool that we thought that we
generated multiple series and saved them to the disk as such, when
in reality, we overwrote the fields of the outgoing metrics via
Go map reference behavior.  This was accidental.  In the course of
diagnosing this, a few errors were found:

1. ``newSeriesFrontier`` should check to see if the candidate fingerprint is within the given domain of the ``diskFrontier``.  If not, as the contract in the docstring stipulates, a ``nil`` ``seriesFrontier`` should be emitted.

2. In the interests of aiding debugging, the raw LevelDB ``levigoIterator`` type now includes a helpful forensics ``String()`` method.

This work produced additional cleanups:

1. ``Close() error`` with the storage stack is technically incorrect, since nowhere in the bowels of it does an error actually occur.  The interface has been simplified to remove this for now.
