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.	12 years ago
Matt T. Proud	c3e3460ca6	Spin up curator run in the tests. After this commit, we'll need to add validations that it does the desired work, which we presently know that it doesn't. Given the changes I made with a plethora of renamings, I want to commit this now before it gets even larger.	12 years ago

Matt T. Proud	6dcaa28806	Include LevelDB fixture generators for curator. This will help reduce common boilerplate for our test process with respect to LevelDB-related things.	12 years ago
Matt T. Proud	b2e4c88b80	Wrap LevelDB iterator operations behind interface. The LevelDB storage types return an interface type now that wraps around the underlying iterator. This both enhances testability but improves upon, in my opinion, the interface design for the LevelDB iterator. Secondarily, the resource reaping behaviors for the LevelDB iterators have been improved by dropping the externalized io.Closer object. Finally, the iterator provisioning methods provide the option for indicating whether one wants a snapshotted iterator or not.	12 years ago
Matt T. Proud	f2a30cf20c	Several important cleanups and deprecations. EachFunc is deprecated. Remove deprecated ``Pair`` and ``GetAll``. These were originally used for forensic and the old gorest impl. Nothing today in the user-facing path nor the tests uses them, especially since the advent of the ForEach protocol in the interface.	12 years ago
Matt T. Proud	8f6b55be71	Several interface cleanups. - Kill Close in Persistent and document interface. - Extract batching behavior into interface. - Kill IteratorManager, which was used for unknown reasons.	12 years ago

Matt T. Proud	ec3e98b365	Include Snappy in Runtime. Snappy should have been explicitly included in the runtime, for I erroneously thought that LevelDB bundled this into its runtime as-is. It turns out that this assumption is wrong, and I thought we had Snappy compression support all-along.	12 years ago
Matt T. Proud	79ba248bbe	Make LevelDB operating modes invocation-time conf. Presently our use of LevelDB and its operating modes are hardcoded into the storage stack. This pull request decouples this and re-exposes this through flags. We can now perform benchmarking and remedial tuning.	12 years ago
Matt T. Proud	ea54751431	Update import paths to new location. This repository moved from matttproud/prometheus to prometheus/prometheus, and all import paths need to be updated.	12 years ago
Matt T. Proud	3ac5d48b1a	Impl' storage i'faces and fix non-idiomatic warts. This change includes implementation of most major storage layer features, albeit some imperfect. It also includes nascent telemetry bindings, too.	12 years ago

Matt T. Proud	15a6681651	Various cleanups. Kill LevelDB watermarks due to redundancy. General interface documentation has begun. Creating custom types for the model to prevent errors down the road. Renaming of components for easier comprehension. Exposition of interface in LevelDB. Slew of simple refactorings.	12 years ago
