Danielle Tomlinson 6b72e96eba client: Move driver/logging to logmon/logging
The logging package is used by logmon and the legacy mock_driver. Because the
legacy drivers are going away, I'm moving it here to signify its actual
ownership.

Danielle Tomlinson 1a29811169 drivers: Move client/drivers/env to drivers/shared/env
As part of deprecating legacy drivers, we're moving the env package to a
new drivers/shared tree, as it is used by the modern docker and rkt
driver packages, and is useful for 3rd party plugins.

Chris Baker da35fda145 testing: in MkAllocDir, do not update TaskConfig with All() from the task builder, just with Env() (because it pollutes environment variables with node attributes and fails the rkt tests) 2018-11-28 22:19:48 +00:00

Michael Schurter 3e56ee005a add nil check around task resources in device hook
Looking at NewTaskRunner I'm unsure whether TaskRunner.TaskResources
(from which req.TaskResources is set) is intended to be nil at times or
if the TODO in NewTaskRunner is intended to ensure it is always non-nil.

Michael Schurter 85073f9d29 client: properly support hook env vars
The old approach was incomplete. Hook env vars are now:

 * persisted and restored between agent restarts
 * deterministic (LWW if 2 hooks set the same key)

Alex Dadgar 4ee603c382 Device hook and devices affect computed node class
This PR introduces a device hook that retrieves the device mount
information for an allocation. It also updates the computed node class
computation to take into account devices.

TODO Fix the task runner unit test. The environment variable is being
lost even though it is being properly set in the prestart hook.

Michael Schurter 944ea6d38b client: emit last sent alloc to new listeners
Fixes a deadlock where the allocwatcher would block forever waiting for
an update from a terminal alloc.

Made the broadcaster easier to debug as well.

Michael Schurter 4f7e6f9464 client: fix races in use of goroutine group
The group utility struct does not support asynchronously launched
goroutines (goroutines-inside-of-goroutines), so switch those uses to a
normal go call.

This means watchNodeUpdates and watchNodeEvents may not be shutdown when
Shutdown() exits. During nomad agent shutdown this does not matter.

During tests this means a test may leak those goroutines or be unable to
know when those goroutines have exited.

Since there's no runtime impact and these goroutines do not affect alloc
state syncing it seems ok to risk leaking them.

Michael Schurter 22771aa19e client/ar: remove useless wait ch from runTasks
Arguably this makes task.WaitCh() useless, but I think exposing a wait
chan from TaskRunners is a generically useful API.
