Bjoern Rabenstein ca6a4fccef Weed out our homegrown test.Tester.
The Go stdlib has testing.TB now, which fulfills the exact same
purpose.

Matt T. Proud 9cde48754b Fix race conditions in TargetPool.
The race condition detector found a few anomalies whereby a
TargetPool could be read during a mutation.  This has been fixed.

Julius Volz f1fc7d717a Allow replacing job targets via HTTP API.
This roughly comprises the following changes:

- index target pools by job instead of scrape interval
- make targets within a pool exchangable while preserving existing
  health state for targets
- allow exchanging targets via HTTP API (PUT)
- show target lists in /status (experimental, for own debug use)

Julius Volz 047eb219e4 Fix target health state update.
Right now, futureState is only used to give hints to the health scheduler, but
nowhere is this future state persisted into the target's state field, so we
don't actually track a target's state over time.

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.

Matt T. Proud 9752f1e61d Refactor Target as interface for testability.
Future tests around the ``TargetPool`` and ``TargetManager`` and
friends will be a lot easier when the concrete behaviors of
``Target`` can be extracted out.  Plus, each ``Target``, I suspect,
will have its own resolution and query strategy.

Matt T. Proud 9af0faaefb Get ``TargetPool`` test working again. 2013-01-13 20:12:38 +01:00
Matt T. Proud d772c6c2b5 Refactor target scheduling to separate facility.
``Target`` will be refactored down the road to support various
nuanced endpoint types.  Thusly incorporating the scheduling
behavior within it will be problematic.  To that end, the scheduling
behavior has been moved into a separate assistance type to improve
conciseness and testability.

``make format`` was also run.

Matt T. Proud 7a9777b4b5 Create ``TargetPool`` priority queue.
``TargetPool`` is a pool of targets pending scraping.  For now, it
uses the ``heap.Interface`` from ``container/heap`` to provide a
priority queue for the system to scrape from the next target.

It is my supposition that we'll use a model whereby we create a
``TargetPool`` for each scrape interval, into which ``Target``
instances are registered.
