This commit makes two reasonably major changes:
Set a default timeout for the go HTTP server (which gin uses), which
allows us to actually have broken long poll sessions fail so we can have
the client re-establish them.
The current 10s number is chosen randomly and we need more testing to
ensure that the feature work as intended.
The second is adding a last updated field to keep track of the last time
we had an update that needs to be propagated to all of our
clients/nodes. This will be used to keep track of our machines and if
they are up to date or need us to push an update.
This commit adds a new field to machine, lastSuccessfulUpdate which
tracks when we last was able to send a proper mapupdate to the node. The
purpose of this is to be able to compare to a "global" last updated time
and determine if we need to send an update map request to a node.
In addition it allows us to create a scheduled check to see if all known
nodes are up to date.
Also, add a helper function to send a message to the update channel of a
machine.
This commit adds integration tests to headscale. They are currently
quite simple, but it lays the groundwork for more comprehensive testing
and ensuring we dont break things with the official tailscale client.
The test works by leveraging Docker (via dockertest) to spin up a
Headscale container, and a number of tailscale containers (10).
Each tailscale container is joined to the headscale and then "passed on"
to the tests.
Currently three tests have been implemented:
- Have all tailscale containers join headscale (in the setup process)
- Get IP from each container (I plan to extend this with cross-ping)
- List nodes with headscales CLI and verify all has been registered
This test depends on Docker, and currently, I have not looked into
hooking it into Github Actions.
This commit makes several changes to the dockerfile:
- Add go.mod and go.sum in a seperate stage, subsequently calling `go
mod download` to make it cache dependencies and speed up builds
- Use ubuntu:latest (28MB larger) instead of scratch, makes the image a
lot easier to debug (e.g. it has a shell and a package manager)
- Change ENTRYPOINT to CMD, this makes the behaviour of the image
slightly different from a CLI perspective, but makes interacting with
the image from code, docker-compose and kubernetes easier.
This is based on the premis that "the user know what command they
executed" and therefor know that the output is the key.
This makes the command a lot more useful in scripts.
This commit tries to detect if users can render colors in their terminal
and only enables color logs if that is true.
It also adds no-color.org's NO_COLOR env var support to allow it to be
disabled.
This commit removes most of the locks in the PollingMap handler as there
was combinations that caused deadlocks. Instead of doing a plain map and
doing the locking ourselves, we use sync.Map which handles it for us.
