events: fix wildcard namespace handling (#10935)
This fixes a bug in the event stream API where it currently interprets
namespace=* as an actual namespace, not a wildcard. When Nomad parses
incoming requests, it sets namespace to default if not specified, which
means the request namespace will never be an empty string, which is what
the event subscription was checking for. This changes the conditional
logic to check for a wildcard namespace instead of an empty one.

It also updates some event tests to include the default namespace in the
subscription to match current behavior.

Fixes #10903

Mahmood Ali 0c2551270a oversubscription: Add MemoryMaxMB to internal structs
Start tracking a new MemoryMaxMB field that represents the maximum memory a task
may use in the client. This allows tasks to specify a memory reservation (to be
used by scheduler when placing the task) but use excess memory used on the
client if the client has any.

This commit adds the server tracking for the value, and ensures that allocations
AllocatedResource fields include the value.

Fixup uses of sanity (#10187)
* Fixup uses of `sanity`
* Remove unnecessary comments.

These checks are better explained by earlier comments about
the context of the test. Per @tgross, moved the tests together
to better reinforce the overall shared context.

* Update nomad/fsm_test.go

prevent double job status update (#9768)
* Prevent Job Statuses from being calculated twice

https://github.com/hashicorp/nomad/pull/8435 introduced atomic eval
insertion iwth job (de-)registration. This change removes a now obsolete
guard which checked if the index was equal to the job.CreateIndex, which
would empty the status. Now that the job regisration eval insetion is
atomic with the registration this check is no longer necessary to set
the job statuses correctly.

* test to ensure only single job event for job register

* periodic e2e

* separate job update summary step

* fix updatejobstability to use copy instead of modified reference of job

* update envoygatewaybindaddresses copy to prevent job diff on null vs empty

* set ConsulGatewayBindAddress to empty map instead of nil

fix nil assertions for empty map

Michael Schurter 9dd59ceaa7 core: improve job deregister error logging
Noticed this error in some production logs, and they were far from
helpful. Changes:

2. Wrap errors and log once instead of double log lines
3. Test fsm error handling behavior

Transaction change tracking
This commit wraps memdb.DB with a changeTrackerDB, which is a thin
wrapper around memdb.DB which enables go-memdb's TrackChanges on all write
transactions. When the transaction is comitted the changes are sent to
an eventPublisher which will be used to create and emit change events.

Mahmood Ali 2c963885b0 handle upgrade path and defaults
Ensure that `""` Scheduler Algorithm gets explicitly set to binpack on
upgrades or on API handling when user misses the value.

The scheduler already treats `""` value as binpack.  This PR merely
ensures that the operator API returns the effective value.

Seth Hoenig 9df33f622f nomad: proxy requests for Service Identity tokens between Clients and Consul
Nomad jobs may be configured with a TaskGroup which contains a Service
definition that is Consul Connect enabled. These service definitions end
up establishing a Consul Connect Proxy Task (e.g. envoy, by default). In
the case where Consul ACLs are enabled, a Service Identity token is required
for these tasks to run & connect, etc. This changeset enables the Nomad Server
to recieve RPC requests for the derivation of SI tokens on behalf of instances
of Consul Connect using Tasks. Those tokens are then relayed back to the
requesting Client, which then injects the tokens in the secrets directory of
the Task.

Seth Hoenig 2b66ce93bb nomad: ensure a unique ClusterID exists when leader (gh-6702)
Enable any Server to lookup the unique ClusterID. If one has not been
generated, and this node is the leader, generate a UUID and attempt to
apply it through raft.

The value is not yet used anywhere in this changeset, but is a prerequisite
for gh-6701.

Blocked evaluation fixes
2018-11-13 10:29:03 -08:00
Alex Dadgar 6d8bb3a7bd Duplicate blocked evals cancelling improved
The old logic for cancelling duplicate blocked evaluations by job id had
the issue where the newer evaluation could have additional node classes
that it is (in)eligible for that we would not capture. This could make
it such that cluster state could change such that the job would make
progress but no evaluation was unblocked.

Alex Dadgar 352f2e03b5 Clean up leaked deployments on restoration
This PR cancels deployments that are active but do not have a job
associated with them. This is a broken invariant that causes issues in
the deployment watcher since it will not track them. Thus they are
objects that can't be operated on or cleaned up.
