Round the node lookup prefix down to the nearest modulo two size before 
performing the lookup.

Reduce the size of the UUID Lookup Length restriction from `8` to `2`. 
I'm torn on this.  It's useful from a UX perspective for an operator to
be able to type in something that's short.  At the same time, by
enforcing an `8` character length, we reduced the probability of a user
depending on the behavior and having it suddenly stop working in the
future when a duplicate prefix is injected into the environment.

Treat a uuid prefix lookup error as a soft error, as if a node name 
lookup returned nil.

Add a TODO to note where a future point of logging should occur once a
logger is present and a few additional comments to explain the program
flow.

Enable looking up consul nodes by their node ID. 
Assuming the following output from a consul agent:

```
==> Consul agent running!
           Version: 'v0.7.3-43-gc5e140c-dev (c5e140c+CHANGES)'
           Node ID: '40e4a748-2192-161a-0510-9bf59fe950b5'
         Node name: 'myhost'
```

it is now possible to lookup nodes by their Node Name or Node ID, or a
prefix match of the Node ID, with the following caveats re: the prefix
match:

1) first eight digits of the Node ID are a required minimum (eight was
   chosen as an arbitrary number)
2) the length of the Node ID must be an even number or no result will be
   returned.

Small premature optimization in `isUUID()`. 
If the length isn't `36`, return `false` immediately before firing up
the regexp engine.

Pass state store pointer into the blocking query work function. 
Previously the blocking functions all closed over the state store from
their first query, with would not have worked properly when a restore
occurred. This makes sure they get a frest state store pointer each time,
and that pointer is synchronized with the abandon watch.

Adds diff check for node and service parts of register requests. 
We always did an update before which caused excessive watch churn, even
with our new fine-grained queries. This does a diff any only updates the
node and service records if something actually changed.

Don't do any watch tracking for non-blocking queries. 2017-01-25 09:58:22 -08:00
James Phillips 05735e39a5
Removes some incorrect comments. 
We can't actually return a fine-grained index from these tables unless
support is added for tombstones. Otherwise, the index could slip backwards
as things are deleted.

James Phillips 32be684fdf
Fixes a startup ordering issue between Raft and Serf. 
This fixes #2663 and fixes #1899. It's not super related to this PR,
but the startup time changes that this PR brings made this a lot worse
so I was able to track it down.
