Copy the updated version of freeport (sdk/freeport), and tweak it for use
in Nomad tests. This means staying below port 10000 to avoid conflicts with
the lib/freeport that is still transitively used by the old version of
consul that we vendor. Also provide implementations to find ephemeral ports
of macOS and Windows environments.
Ports acquired through freeport are supposed to be returned to freeport,
which this change now also introduces. Many tests are modified to include
calls to a cleanup function for Server objects.
This should help quite a bit with some flakey tests, but not all of them.
Our port problems will not go away completely until we upgrade our vendor
version of consul. With Go modules, we'll probably do a 'replace' to swap
out other copies of freeport with the one now in 'nomad/helper/freeport'.
This is a workaround for the windows process model.
Go os/exec does not pass the parent process handle to the child
processes STARTUPINFO struct, this means that unless we wait in
the _same_ execution context as Starting the process, the
handle will be lost, and we cannot kill it without regaining
a handle.
A better long term solution would be a higher level process
abstraction that uses windows.CreateProcess on windows.
When vault is installed through chocolatey, it also installs a shim that
will not pass kill signals to the child. This means the process will
never actually terminate, and we lose the process handle.
Here, rather than waiting forever, we timeout fast.
This drops the testings stdlib pkg from our dependencies. Saves a
whopping 46kb on our binary (was really hoping for more of a win there),
but also avoids potential ugliness with how testing sets flags.
