Michael Schurter 1769db98b7 Fix regression by returning error on unknown alloc 2017-11-01 15:16:38 -05:00
Michael Schurter 73e9b57908 Trigger GCs after alloc changes
GC much more aggressively by triggering GCs when allocations become
terminal as well as after new allocations are added.

Michael Schurter 2a81160dcd Fix GC'd alloc tracking
The Client.allocs map now contains all AllocRunners again, not just
un-GC'd AllocRunners. Client.allocs is only pruned when the server GCs
allocs.

Also stops logging "marked for GC" twice.

Alex Dadgar 4831380e57 Node access is done using locked Node copy
Fixes https://github.com/hashicorp/nomad/issues/3454

Reliably reproduced the data race before by having a fingerprinter
change the nodes attributes every millisecond and syncing at the same
rate. With fix, did not ever panic.

Alex Dadgar 07ed83fdd5 Non-locked accessors to common Node fields
This PR removes locking around commonly accessed node attributes that do
not need to be locked. The locking could cause nodes to TTL as the
heartbeat code path was acquiring a lock that could be held for an
excessively long time. An example of this is when Vault is inaccessible,
since the fingerprint is run with a lock held but the Vault
fingerprinter makes the API calls with a large timeout.

interface has 3 implementations:

1. local for blocking and moving data locally
2. remote for blocking and moving data from another node

Michael Schurter e204a287ed Refactor Consul Syncer into new ServiceClient
Fixes #2478 #2474 #1995 #2294

The new client only handles agent and task service advertisement. Server
discovery is mostly unchanged.

The Nomad client agent now handles all Consul operations instead of the
executor handling task related operations. When upgrading from an
earlier version of Nomad existing executors will be told to deregister
from Consul so that the Nomad agent can re-register the task's services
and checks.

Drivers - other than qemu - now support an Exec method for executing
abritrary commands in a task's environment. This is used to implement
script checks.

Interfaces are used extensively to avoid interacting with Consul in
tests that don't assert any Consul related behavior.
