server/vault: Lock Vault expiration tracking
2018-12-04 19:46:59 -05:00
Mahmood Ali 50e38104a5 server/nomad: Lock Vault expiration tracking
`currentExpiration` field is accessed in multiple goroutines: Stats and
renewal, so needs locking.

I don't anticipate high contention, so simple mutex suffices.

Danielle Tomlinson d4cbd608ff nomad: Remove on-submission job validation
With the introduction of driver plugins, we're temporarily relying on

time.

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 56ed4f01be vault: fix panic by checking for nil secret
Vault's RenewSelf(...) API may return (nil, nil). We failed to check if
secret was nil before attempting to use it.

RenewSelf:
e3eee5b4fb/api/auth_token.go (L138-L155)

Calls ParseSecret:
e3eee5b4fb/api/secret.go (L309-L311)

If anyone has an idea on how to test this I didn't see any options. We
use a real Vault service, so there's no opportunity to mock the
response.

Danielle Tomlinson 9c72dafc95 scheduler: Add is_set/is_not_set constraints
This adds constraints for asserting that a given attribute or value
exists, or does not exist. This acts as a companion to =, or !=
operators, e.g:

```hcl
constraint {
        attribute = "${attrs.type}"
        operator  = "!="
        value     = "database"
}

constraint {
        attribute = "${attrs.type}"
        operator  = "is_set"
}

Mahmood Ali 4e18846fd9 Adjust streaming duration
This test expects 11 repeats of the same message emitted at intervals of
200ms; so we need more than 2 seconds to adjust for time sleep
variations and the like.  So raising it to 3s here that should be
enough.

Mahmood Ali 9c0a15f3ce Run job deregistering in a single transaction
Fixes https://github.com/hashicorp/nomad/issues/4299

Upon investigating this case further, we determined the issue to be a race between applying `JobBatchDeregisterRequest` fsm operation and processing job-deregister evals.

Processing job-deregister evals should wait until the FSM log message finishes applying, by using the snapshot index.  However, with `JobBatchDeregister`, any single individual job deregistering was applied accidentally incremented the snapshot index and resulted into processing job-deregister evals.  When a Nomad server receives an eval for a job in the batch that is yet to be deleted, we accidentally re-run it depending on the state of allocation.

This change ensures that we delete deregister all of the jobs and inserts all evals in a single transactions, thus blocking processing related evals until deregistering complete.
