Not sure if this was meant to imply adding more schedulers to Nomad is
easy, or that we plan on adding pluggable schedulers. Either way,
neither of those statements is really true unless you really stretch the
definitions of "easy" and "plan".
So remove this sentence as I can't imagine it does anything other than
confuse people.
Thanks to @notnoop for this UX improvement suggestion.
The allocation’s task group is always known, so it
might as well be preselected in the sidebar when the
exec window opens. Also, if the task group only has
one task, might as well preselect it too.
This closes#8422, another bug facilitated by the difficulty
of automated testing when opening another window. Thanks to
@notnoop for narrowing this down.
Bring Nomad in line with other HashiCorp projects and remove stalebot. We get
little value in cleaning up issues automatically this way, it adds extra work
for maintainers when we have issues waiting on the backlog that we intend to
do, and it presents an unkind experience to issue contributors who get their
issues closed by an impersonal bot.
The reconcile loop sets `DeploymentState.DesiredCanaries` only on the first
pass through the loop and if the job is not paused/pending. In MRD,
deployments will make one pass though the loop while "pending", and were not
ever getting `DesiredCanaries` set. We can't set it in the initial
`DeploymentState` constructor because the first pass through setting up
canaries expects it's not there yet. However, this value is static for a given
version of a job because it's coming from the update stanza, so it's safe to
re-assign the value on subsequent passes.
The field name `Deployment.TaskGroups` contains a map of `DeploymentState`,
which makes it a little harder to follow state updates when combined with
inconsistent naming conventions, particularly when we also have the state
store or actual `TaskGroup`s in scope. This changeset changes all uses to
`dstate` so as not to be confused with actual TaskGroups.

If a job update includes a task group that has no changes, those allocations
have their version bumped in-place. The ends up triggering an eval from
`deploymentwatcher` when it verifies their health. Although this eval is a
no-op, we were only treating pending deployments the same as paused when
the deployment was a new MRD. This means that any eval after the initial one
will kick off the deployment, and that caused pending deployments to "jump
the queue" and run ahead of schedule, breaking MRD invariants and resulting in
a state with all regions blocked.
This behavior can be replicated even in the case of job updates with no
in-place updates by patching `deploymentwatcher` to inject a spurious no-op
eval. This changeset fixes the behavior by treating pending deployments the
same as paused in all cases in the reconciler.
