Tomás Senart 09c58ce481 Upgrade to Go 1.4
This change set upgrades Prometheus to use Go 1.4
The other modifications were intended to compare benchmarks between the
old and new versions using `golang.org/x/tools/cmd/benchcmp`.

Bjoern Rabenstein 006b5517e2 Simplify makefiles.
This removes the dependancy on C leveldb and snappy.
It also takes care of fewer dependencies as they would
anyway not work on any non-Debian, non-Brew system.

Julius Volz c6e9f085a3 Update used Go version to 1.3.
Go downloads moved to a different URL and require following redirects
(curl's '-L' option) now.

Go 1.3 deliberately randomizes ranges over maps, which uncovered some
bugs in our tests. These are fixed too.

Matt T. Proud 3e969a8ca2 Parameterize the buffer for marshal/unmarshal.
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.

Matt T. Proud e9eda76192 Fix Mac OS X build since we upgraded to go1.2.
Since go1.2, the release engineers have keyed their release
artifacts to the major release family of Mac OS X.

Julius Volz 44390d831d Introduce semantic versioning.
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.

Bjoern Rabenstein 1f90abdc1f Add -O3 to all C/C++ compiles.
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%.

Julius Volz 6b7de31a3c Upgrade to LevelDB 1.14.0 to fix LevelDB bugs.
This tentatively fixes https://github.com/prometheus/prometheus/issues/368 due
to an upstream bugfix in snapshotted LevelDB iterator handling, which got fixed
in LevelDB 1.14.0:

Johannes 'fish' Ziemke d438e1c96c Allow overriding url to fetch go from by env var
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.

Matt T. Proud 9c8112a053 Revert "Add flags to build prometheus statically"
This reverts commit 0e9e3e068d.

Not only do we know this to produce problematic artifacts, it refuses
to build on Mac OS X.

Matt T. Proud 3784b1779f Upgrade LevelDB to 1.12.0.
A number of core fixes have occurred in upstream LevelDB.  Given API
compatibility, we should upgrade.

Matt T. Proud 9215580488 Include race condition binary target.
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.

Matt T. Proud 244a4a9cdb Update to go1.1.
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.

Matt T. Proud 161c8fbf9b Include deletion processor for long-tail values.
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.
