Prevent duplicate servers being added in AddPrimaryServer. 
This logic was already present elsewhere and was missed in this one
place.

Create a consulContext using a client's consul config. 
This is wrong and should be the Agent's Consul Config.  This is a
step in the right direction, so committing to mark the necessary
future change.

Populate the RPC Proxy's server list if heartbeat did not include a leader. 
It's possible that a Nomad Client is heartbeating with a Nomad server that
has become issolated from the quorum of Nomad Servers.  When 3x the
heartbeatTTL has been exceeded, append the Consul server list to the primary
primary server list.  When the next RPCProxy rebalance occurs, there is a
chance one of the servers discovered from Consul will be in the majority.
When client reattaches to a Nomad Server in the majority, it will include
a heartbeat and will reset the TTLs *AND* will clear the primary server list
to include only values from the heartbeat.

Rename structs.Task's Service attribute to ConsulService 2016-06-10 15:54:39 -04:00
Sean Chittenden 8c813630e6
Move package client/consul/sync to command/agent/consul. 
This has been done to allow the Server and Client to reuse the same
Syncer because the Agent may be running Client, Server, or both
simultaneously and we only want one Syncer object alive in the agent.
 2016-06-10 15:54:39 -04:00
Sean Chittenden d6ef97911b
Rename Syncer.SetServiceIdentifier to SetServiceRegPrefix() 
This attribute isn't actually an identifier because it can represent
a collection of services.  Rename `serviceIdentifier` to
`serviceRegPrefix which more accurately conveys the intention of this
Syncer attribute.

While here, also rename `SetServiceIdentifier()` to `SetServiceRegPrefix()`
and `GenerateServiceIdentifier()` to `GenerateServicePrefix()`.
 2016-06-10 15:54:39 -04:00
Sean Chittenden 6b126ce488
Change the API signature of Syncer.SyncServices(). 
SyncServices() immediately attempts to sync whatever information
the process has with Consul.  Previously this method would take an
argument of the exclusive list of services that should exist,
however this is not condusive to having a Nomad Client and Nomad
Server share the same consul.Syncer.

Change the signature of the PeriodicCallback to return an error 
I *KNEW* I should have done this when I wrote it, but didn't want to
go back and audit the handlers to include the appropriate return
handling, but now that the code is taking shape, make this change.

Change client/consul.NewSyncer() to accept a shutdown channel 
In addition to the API changing, consul.Syncer can now be signaled
to shutdown via the Shutdown() method, which will call the Run()'ing
sync task to exit gracefully.

Rename rpcproxy.UpdateFromNodeUpdateResponse to RefreshServerLists

arguments to RefreshServerLists.  The servers parameter is reusing
`structs.NodeServerInfo` for the time being, but this can be revisited
if the needs of the strucutre diverge in the future.

Make the locking protocol more explicit in client.NewClient 
With an over abundance of caution, preevnt future copy/pasta by
using the right locks when bootstrapping a Client.  Strictly speaking
this is not necessary, but it makes explicit the locking semantics
and guards against future concurrent or parallel initialization.

Register two services each for clients and servers, http and rpc. 
In order to give clients a fighting chance to talk to the right port,
differentiate RPC services from HTTP services by registering two
services with different tags.  This yields
`rpc.nomad-server.service.consul` and
`http.nomad-server.service.consul` which is immensely more useful to
clients attempting to bootstrap their world.

Establish a floor of one core for the number of cores. 
In most cases the upstream library [shirou/gopsutil](https://github.com/shirou/gopsutil)

 2016-05-09 11:56:35 -07:00
Sean Chittenden 2ff8b10e05
Rename cgroup_universal.go to cgroup_default.go 
Universal implies it is applicable to Linux, whereas default implies
the fallthrough for the non-Linux build targets.
 2016-05-09 11:56:35 -07:00
Sean Chittenden f8e9a759d3
Move network detection code to Linux-specific build 
Non-Linux build targets get the current default of 0.  This will allow
platform specific fingerprinting for network capabilities.

Sean Chittenden d1268cfb76 Break out the windows vs UNIX Fingerprinter 
cgroup's are applicable to Windows and will require a more specific abstraction.  Stub out the difference.  The *NIX exec drivers will likely be broken out over time (e.g. *BSD and Solaris).

Sean Chittenden 1314227863 Explicitly enumaret the build targets in _unix 
`!windows` was being used as the synonym for `darwin dragonfly freebsd linux netbsd openbsd solaris`.  While I don't imagine `android` will be a prime target for Nomad in the near term, favor explicit build targets.
