Properly guard consulPullHeartbeatDeadline behind heartbeatLock
2016-06-10 15:54:39 -04:00

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.

This has been done to allow the Server and Client to reuse the same

simultaneously and we only want one Syncer object alive in the agent.

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

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.

Allow ports to be optional when adding servers
...
When updating a clients servers, as nomad does not use the gossip
protocol over a specified port for clients, it was required to specify
ports along with server addresses.
Now specifying ports are optional, and if unspecified the default `4647`
port is used, reflecting a notice back to the user.
