Moves the FSM into its own package. 
This will help make it clearer what happens when we add some registration
plumbing for the different operations and snapshots.

Creates a registration mechanism for RPC endpoints. 2017-11-29 18:36:52 -08:00
James Phillips d1ad538345 Makes RPC handling more robust when rolling servers. (#3561) 
* Adds client-side retry for no leader errors.

This paves over the case where the client was connected to the leader
when it loses leadership.

* Adds a configurable server RPC drain time and a fail-fast path for RPCs.

When a server leaves it gets removed from the Raft configuration, so it will
never know who the new leader server ends up being. Without this we'd be
doomed to wait out the RPC hold timeout and then fail. This makes things fail
a little quicker while a sever is draining, and since we added a client retry
AND since the server doing this has already shut down and left the Serf LAN,
clients should retry against some other server.

* Makes the RPC hold timeout configurable.

* Reorders struct members.

* Sets the RPC hold timeout default for test servers.

* Bumps the leave drain time up to 5 seconds.

* Robustifies retries with a simpler client-side RPC hold.

* Reverts untended delete.

James Phillips fcaa889116 Bumps default Raft protocol to version 3. (#3477) 
* Changes default Raft protocol to 3.

* Changes numPeers() to report only voters.

This should have been there before, but it's more obvious that this
is incorrect now that we default the Raft protocol to 3, which puts
new servers in a read-only state while Autopilot waits for them to
become healthy.

* Fixes TestLeader_RollRaftServer.

* Fixes TestOperator_RaftRemovePeerByAddress.

* Fixes TestServer_*.

Relaxed the check for a given number of voter peers and instead do
a thorough check that all servers see each other in their Raft
configurations.

* Fixes TestACL_*.

These now just check for Raft replication to be set up, and don't
care about the number of voter peers.

* Fixes TestOperator_Raft_ListPeers.

* Fixes TestAutopilot_CleanupDeadServerPeriodic.

* Fixes TestCatalog_ListNodes_ConsistentRead_Fail.

* Fixes TestLeader_ChangeServerID and adjusts the conn pool to throw away
sockets when it sees io.EOF.

* Changes version to 1.0.0 in the options doc.

* Makes metrics test more deterministic with autopilot metrics possible.

James Phillips 247f4a7e41 Simplifies Serf dynamic port selection code. 
This isn't racy, it's just a little dirty. The listen will happen and a port
will be selected and injected into the config once the Serf instance is
created, so we don't need the retry loop here.

Frank Schroeder b3189a566a rpc: refactor sessionTimers and fix racy tests 
The sessionTimers map was secured by a lock which wasn't used
properly in the tests. This lead to data races and failing tests
when accessing the length or the members of the map.

This patch adds a separate SessionTimers struct which is safe
for concurrent use and which ecapsulates the behavior of the
sessionTimers map.

Frank Schroeder c33f7ecbe2 rpc: discover serf wan port before starting serf lan 
When using dynamic ports for the serf clusters then
the actual bind port of the serf WAN cluster needs to
be discovered before the serf LAN cluster is started
since the serf LAN cluster announces the port of the WAN
cluster.

Frank Schroeder d3ab99244b agent: make the RPC endpoint overwrite mechanism more transparent 
This patch hides the RPC handler overwrite mechanism from the
rest of the code so that it works in all cases and that there
is no cooperation required from the tested code, i.e. we can
drop a.getEndpoint().

Frank Schroeder e930b55f71 agent: move the SnapshotReplyFn out of the way

the SnapshotReplyFn needs to be in a separate package to avoid
a circular dependency.
