Sean Chittenden 01b8311c94 Include the current version along side the available version.
When checkpoint emits a log message indicating an agent is out of
date, include the current version along with the available version
according to checkpoint.

Sean Chittenden 7a814fce63 Print a helpful message re: duplicate addresses
IP sockets provide nice endpoints where the kernel will fail to bind and will error out saying socket already in use.  UNIX sockets, however, don't enjoy this nice property when cleaning up stale sockets on listen.  Given the number of addresses in Consul, provide operators with a helpful message that indicates the source of the reused address.

Before this fix, it was possible for the HTTP socket to unlink the RPC socket, leading to confusing blocked behavior when running commands like `consul info`.

```
% cat tmp.config.json
{
    "addresses": {
	"http": "unix:///tmp/.consul.sock",
	"rpc": "unix:///tmp/.consul.sock"
    },
    "unix_sockets": {
	"mode": "0700"
    }
}
% consul agent -config-file tmp.config.json -advertise=127.0.0.1 -data-dir=/tmp/
==> All listening endpoints must be unique: HTTP address already configured for RPC
Exit 1
```

Sean Chittenden 5994c9efbf skip_leave_on_int's default changes based on agent mode

Miquel Sabaté Solà 4567963d8e command: deprecated the -dc flag in the agent CLI
The `-dc` flag from the agent CLI command has been deprecated in favor of
`-datacenter`. This is done this way because:

- Other CLI commands used `-datacenter`. See: event, exec and watch.
- The agent configuration file uses `datacenter`.

These would manifest in the HTTP output as Javascript nulls instead of

convert nil slices to empty ones so they JSON-ify properly, and we added
tests to catch this in the future.

Wojciech Bederski b014c0f91b make Pause()/Resume()/isPaused() behave more like a semaphore
see: https://github.com/hashicorp/consul/issues/1173 #1173

Reasoning: somewhere during consul development Pause()/Resume() and
PauseSync()/ResumeSync() were added to protect larger changes to
agent's localState.  A few of the places that it tries to protect are:

- (a *Agent) AddService(...)      # part of the method
- (c *Command) handleReload(...)  # almost the whole method
- (l *localState) antiEntropy(...)# isPaused() prevents syncChanges()

The main problem is, that in the middle of handleReload(...)'s
critical section it indirectly (loadServices()) calls  AddService(...).
AddService() in turn calls Pause() to protect itself against
syncChanges(). At the end of AddService() a defered call to Resume() is
made.

With the current implementation, this releases
isPaused() "lock" in the middle of handleReload() allowing antiEntropy
to kick in while configuration reload is still in progress.
Specifically almost all services and probably all check are unloaded
when syncChanges() is allowed to run.

This in turn can causes massive service/check de-/re-registration,
and since checks are by default registered in the critical state,
a majority of services on a node can be marked as failing.
It's made worse with automation, often calling `consul reload` in close
proximity on many nodes in the cluster.

This change basically turns Pause()/Resume() into P()/V() of
a garden-variety semaphore. Allowing Pause() to be called multiple times,
and releasing isPaused() only after all matching/defered Resumes() are
called as well.

TODO/NOTE: as with many semaphore implementations, it might be reasonable
to panic() if l.paused ever becomes negative.

Peter Fern b023904298 Add TCP check type
Adds the ability to simply check whether a TCP socket accepts
connections to determine if it is healthy.  This is a light-weight -
though less comprehensive than scripting - method of checking network
service health.

The check parameter `tcp` should be set to the `address:port`
combination for the service to be tested.  Supports both IPv6 and IPv4,
in the case of a hostname that resolves to both, connections will be
attempted via both protocol versions, with the first successful
connection returning a successful check result.

Example check:

```json
{
  "check": {
    "id": "ssh",
    "name": "SSH (TCP)",
    "tcp": "example.com:22",
    "interval": "10s"
  }
}

Hans Hasselberg 267e0caf81 Implement advertise_addrs for SerfLan, SerfWan and RPC.
Fixes #550.
This will make it possible to configure the advertised adresses for
SerfLan, SerfWan and RPC. It will enable multiple consul clients on a
single host which is very useful in a container environment.

This option might override advertise_addr and advertise_addr_wan
depending on the configuration.

It will be configureable with advertise_addrs. Example:

{
  "advertise_addrs": {
    "serf_lan": "10.0.120.91:4424",
    "serf_wan": "201.20.10.61:4423",

Jeff Mitchell 11a3ce0bdd RPC and HTTP interfaces fully generically-sockified so Unix is supported.
Client works for RPC; will honor CONSUL_RPC_ADDR. HTTP works via consul/api;
honors CONSUL_HTTP_ADDR.

The format of a Unix socket in configuration data is:
"unix://[/path/to/socket];[username or uid];[gid];[mode]"

Obviously, the user must have appropriate permissions to create the socket
file in the given path and assign the requested uid/gid. Also note that Go does
not support gid lookups from group name, so gid must be numeric. See
https://codereview.appspot.com/101310044

When connecting from the client, the format is just the first part of the
above line:
"unix://[/path/to/socket]"

Atin Malaviya 4732c36d88 Consul Session TTLs
The design of the session TTLs is based on the Google Chubby approach
(http://research.google.com/archive/chubby-osdi06.pdf). The Session
struct has an additional TTL field now. This attaches an implicit
heartbeat based failure detector. Tracking of heartbeats is done by
the current leader and not persisted via the Raft log. The implication
of this is during a leader failover, we do not retain the last
heartbeat times.

Similar to Chubby, the TTL represents a lower-bound. Consul promises
not to terminate a session before the TTL has expired, but is allowed
to extend the expiration past it. This enables us to reset the TTL on
a leader failover. The TTL is also extended when the client does a
heartbeat. Like Chubby, this means a TTL is extended on creation,
heartbeat or failover.

Additionally, because we must account for time requests are in transit
and the relative rates of clocks on the clients and servers, Consul
will take the conservative approach of internally multiplying the TTL
by 2x. This helps to compensate for network latency and clock skew
without violating the contract.

Ryan Uber b7587cac42 agent: allow config reload to modify checks/services persistence
This change consolidates loading services and checks from both config
and persisted state into methods on the agent. As part of this, we
introduce optional persistence when calling RemoveCheck/RemoveService.

Fixes a bug where config reloads would kill persisted services/checks.
Also fixes an edge case:

1. A service or check is registered via the HTTP API
2. A new service or check definition with the same ID is added to config
3. Config is reloaded

The desired behavior (which this implements) is:

1. All services and checks deregistered in memory
2. All services and checks in config are registered first
3. All persisted checks are restored using the same logic as the agent
   start sequence, which prioritizes config over persisted, and removes
   any persistence files if new config counterparts are present.
