This adds functionality to ensure that connections are closed on a
worker when the server is shut down or reloaded.
Connections are closed, and then the shutdown process waits for the next
report to the controller to go through, waiting the grace period that
was added in #1330. The rest of shutdown is then proceeded with.
Listener shutdown has been moved to the start of the process to ensure
that new connections can't be made while we are shutting down.
Additionally, functionality has been added to force shut down servers
after a second interrupt has been received after the first one. This
takes the form of code in both the server and dev mode code paths that
just performs an os.Exit if another shutdown is received during the
normal shutdown process.
Additionally, the commit also includes some refactoring to tests so that
we could use some of the new E2E testing code to test session
connections during shutdown and reload.
Additionally, this fixes a panic in worker startup when there are no
controllers defined. Looks like the shutdown call was attempting to call
into the controller, not the worker.
Finally, this also removes the extra shutdown within the outer worker
startup.
Shutdown is actually handled within the inner StartWorker(), attempting
shutdown on errors was actually leading to potential use of an
uninitialized worker, which is leading to panics in testing.
* updated dockerfile to support multi-arch; added new section in Make for multi-arch
* adding a line to changelog
* switching base image to hashicorp mirror
This is very useful when trying to write managed groups filters as you
can directly look at the structure of the claims for the accounts you're
trying to filter.
The output of the claims in text format on the CLI currently leaves
something to be desired. I started revamping some of the formatting
functions and it quickly got very fragile. Fundamentally at this point
we're likely better off -- now that we have a good idea what our output
format/standards are like -- rewriting the formatting code. I'll take
that as a tasker as I have a lot of ideas...
* Bump to Go 1.16.6, which fixes some important issues
* use linux/arm64 golang base image
- Discovered the correct digest using:
'docker manifest inspect golang:1.16.6 | jq -r '.manifests[] | select(.platform.os == "linux" and .platform.architecture == "amd64") | .digest'

This fixes this test which was failing intermittently.
* Ups the grace period timeout to 2s.
* Re-positions the testify require.New() so that incorrect code path
warnings are not given.
This commit adds the support to do the following:
* Mark connections for non-reporting workers as closed. This is the
controller counterpart to the worker functionality (see #1330). This is
written as a scheduled job that does the work DB-side in a single atomic
query.
* Works to reconcile states if such a broken controller-worker
connection resumes and a worker reports a connection as connected that
should be disconnected. In this case, the controller will send an update
request, and the worker will honor it and terminate the connection.
* Further refinement of the grace period setting has been added here.
We have converged on the current server "liveness" setting as our
default here, which is half of the previous 30s (15 seconds, in other
words). Additionally, this is now configurable on the controller and
worker side, with the caveat that it's currently impossible to do so in
config as the setting has been untagged in HCL. This is exposed so that
we can run some sophisticated testing scenarios where we skew the grace
period to either the controller or worker to ensure the aforementioned
reconciliation works.
* Some repository functions have been added to support the new
functionality, in addition to some test code to the worker to allow
querying of session state while testing.
* Finally, we've added some add timestamp subtraction functions
as well, basically serving as the opposite of the addition functions.
This adds enumeration constraints to the server table, ensuring that no
servers can be added other than the types "controller" and "worker".
This should already be impossible to do in code, but this adds a check
on the database level to ensure it's the case as well.
