This PR takes the host ID and runs it through a hash so that it is well
distributed. This makes it so that machines that report similar host IDs
are easily distinguished.
Instances of similar IDs occur on EC2 where the ID is prefixed and on
motherboards created in the same batch.

We used to be checking a RequireTLS field that was never set. Instead we
can just check the TLSConfig.EnableRPC field and require TLS if it's
enabled.
Added a few unfortunately slow integration tests to assert the intended
behavior of misconfigured RPC TLS.
Also disable a lot of noisy test logging when -v isn't specified.
Fixes an issue where the Ruby runtime expects the sticky bit to be set
on the temp directory. The sticky bit is commonly set on the temp
directory since it is usually shared by many users. This change brings
ours in line with that assumption.
This PR adds tracking to when a task starts and finishes and the logs
API takes advantage of this and returns better errors when asking for
logs that do not exist.
This PR fixes token revocation and adds tests to make sure it is
working. The 0.5.6 RC1's token revocation does not work becasue the
token's value is captured at the instantiation of the deferred
stoprenewal statement rather than its exectution.
This PR allows accessing the Node's attributes and metadata as in a
template.
```
template {
data = "{{ env \"attr.unique.network.ip-address\" }}"
destination = "local/out"
}
```
This PR fixes an issue that is hit when running templates with restart
mode in which the client could panic when the handle is not running.

This PR fixes two issues:
* Folder permissions in -dev mode were incorrect and not suitable for
running as a particular user.
* Was not setting the group membership properly for the launched
process.
Fixes https://github.com/hashicorp/nomad/issues/2160
This PR:
* Uses Go 1.8 executable lookup
* Stores any err message from stats init method
* Allows overriding of Cpu Compute for hosts where it can't be detected
This PR introduces a parallelism limit during garbage collection. This
is used to avoid large resource usage spikes if garbage collecting many
allocations at once.
This PR adds the following metrics to the client:
client.allocations.migrating
client.allocations.blocked
client.allocations.pending
client.allocations.running
client.allocations.terminal
Also adds some missing fields to the API version of the evaluation.
This commit adds Solaris versions of the following functions:
- `linkDir`
- `unlinkDir`
- `createSecretDir`
- `removeSecretDir`
I believe this requires Go 1.8 in order to compile, as the unlink
syscall was previously missing.
Previously, this value was guarded against running on Windows
because it called the `uname` command which is unlikely to
be there.
This change now sets the value from gopsutil, which might
well be an empty string.

Previously with client fingerprinting, sys/exec's Command
function was being used to execute `uname -r` and the return
string processed into the kernel.version node attribute.
This change uses gopsutil/host KernelVersion function
instead. This means we can drop the os/exec, strings and
fmt imports... and not execute an external binary.

This PR fixes two issues:
1) A close of a nil stopCollection channel when restoring and prestart
fails. The failure will cause the killCh to be triggered which will
close collection before it has been initialized.
2) Fixes a deadlock in which the handleWaitCh is never triggered since
it is not initialized when there is an error in prestart and the killCh
is triggered.
Both fixes are by maintaining the loop invariant that the two channels
are valid after there is a handle.
This PR fixes our vet script and fixes all the missed vet changes.
It also fixes pointers being printed in `nomad stop <job>` and `nomad
node-status <node>`.
This PR introduces a coordinator for doing CRUD on a Docker image. It
should fix racy deletion of images. The issue before was images would be
deleted between prestart and start causing an error.
A change in the behavior of `os.Rename` in Go 1.8 brought to light a
difference in the logic between `{Alloc,Task}Runner` and this test:
AllocRunner builds the alloc dir, moves dirs if necessary, and then lets
TaskRunner call TaskDir.Build().
This test called `TaskDir.Build` *before* `AllocDir.Move`, so in Go 1.8
it failed to `os.Rename over` the empty {data,local} dirs.
I updated the test to behave like the real code, but I defensively added
`os.Remove` calls as a subtle change in call order shouldn't break this
code. `os.Remove` won't remove a non-empty directory, so it's still
safe.
