juliusv 09d543de97 Merge pull request #35 from matttproud/fix/targetpool-and-manager-queueing
``TargetManager`` and ``TargetPool`` as pointers.

Refactor Target into Interface to Enhance Testability
2013-01-15 07:22:15 -08:00
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 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 f1a4f26d3b Merge pull request #30 from matttproud/fix/get-metrics-for-labelset-semantics
``GetFingerprintsForLabelSet`` uses intersection.

Matt T. Proud d9b165220e `GetFingerprintsForLabelSet` uses intersection.
This implementation needs to be cleaned up considerably, but it
should hopefully provide some breathing room.  Ultimately this will
be extracted out of the storage layer---specifically the LevelDB
hierarchy---to interface with a generic set of abstractions for a
storage system, but this will be where it remains for now.

Julius Volz cb6eb30182 Fix state cleanup bug between rule/config parser runs.
This fixes a bug that has been annoying me minorly for some time now:
sometimes, after parse errors, a subsequent parser run would fail.  The reason
is that yylex() modifies some global variables (yytext, yydata) during its run
to keep state. To make subsequent parser runs correct, these have to be reset
before each run.

Also, close files after reading them.

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.
