We are not reusing buffers yet. This could introduce problems,
so the behavior is disabled for now.
Cursory benchmark data:
- Marshal for 10,000 samples: -30% overhead.
- Unmarshal for 10,000 samples: -15% overhead.

Since go1.2, the release engineers have keyed their release
artifacts to the major release family of Mac OS X.

This introduces semantic versioning (http://semver.org/) in Prometheus:
- A new VERSION file contains the semantic version string.
- The "tarball" target now includes versioning and build information in
the tarball name, like: "prometheus-0.1.0.linux-amd64.tar.gz".
- A new "release" target allows scp-ing the versioned tarball to a
remote machine (file server).
- A new "tag" target allows git-tagging the current revision with the
version specified in VERSION.

So far, we are compiling C/C++ code without any optimization.
In non-representative, but practically relevant tests, the -O3
improved the total query time for a demanding graph by ~20%.

If you want to use a different binary package than the officially
provided, you now can point the env var GOURL to the package you
want to get instead.

This reverts commit 0e9e3e068d.
Not only do we know this to produce problematic artifacts, it refuses
to build on Mac OS X.

The race condition binary target is special in that it needs to
explicitly link against the dependent libraries and recompile the CGO
bindings. Because of this, we have a new build target that produces
these binaries.
This commit updates the documentation, Makefiles, formatting, and
code semantics to support the 1.1. runtime, which includes ...
1. ``make advice``,
2. ``make format``, and
3. ``go fix`` on various targets.
This commit extracts the model.Values truncation behavior into the actual
tiered storage, which uses it and behaves in a peculiar way—notably the
retention of previous elements if the chunk were to ever go empty. This is
done to enable interpolation between sparse sample values in the evaluation
cycle. Nothing necessarily new here—just an extraction.
Now, the model.Values TruncateBefore functionality would do what a user
would expect without any surprises, which is required for the
DeletionProcessor, which may decide to split a large chunk in two if it
determines that the chunk contains the cut-off time.
