Version information is determined at build-time and thus there is
no need to pass it down from main. In its own package it can
be used from various other packages.
Resolves#609 by removing two dependencies on git.
- Use the Makefile to find the current directory.
- In the case of building from an archive fall back to fixed REV
and BRANCH values.
We were using Godep incorrectly (cloning repos from the internet during
build time instead of including Godeps/_workspace in the GOPATH via
"godep go"). However, to avoid even having to fetch "godeps" from the
internet during build, this now just copies the vendored files into the
GOPATH.
Also, the protocol buffer library moved from Google Code to GitHub,
which is reflected in these updates.
This fixes https://github.com/prometheus/prometheus/issues/525
- Move CONTRIBUTORS.md to the more common AUTHORS.
- Added the required NOTICE file.
- Changed "Prometheus Team" to "The Prometheus Authors".
- Reverted the erroneous changes to the Apache License.
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.

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.

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.
