Avery Pennarun	0181a4d0ac	ipnlocal: don't pause the controlclient until we get at least one netmap. ... Without this, macOS would fail to display its menu state correctly if you started it while !WantRunning. It relies on the netmap in order to show the logged-in username.

Avery Pennarun	4ef207833b	ipn: !WantRunning + !LoggedOut should not be idle on startup. ... There was logic that would make a "down" tailscale backend (ie. !WantRunning) refuse to do any network activity. Unfortunately, this makes the macOS and iOS UI unable to render correctly if they start while !WantRunning. Now that we have Prefs.LoggedOut, use that instead. So `tailscale down` will still allow the controlclient to connect its authroutine, but pause the maproutine. `tailscale logout` will entirely stop all activity. This new behaviour is not obviously correct; it's a bit annoying that `tailsale down` doesn't terminate all activity like you might expect. Maybe we should redesign the UI code to render differently when disconnected, and then revert this change. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
Avery Pennarun	4f3315f3da	ipnlocal: setting WantRunning with EditPrefs was special. ... EditPrefs should be just a wrapper around the action of changing prefs, but someone had added a side effect of calling Login() sometimes. The side effect happened *after* running the state machine, which would sometimes result in us going into NeedsLogin immediately before calling cc.Login(). This manifested as the macOS app not being able to Connect if you launched it with LoggedOut=false and WantRunning=false. Trying to Connect() would sent us to the NeedsLogin state instead.

Avery Pennarun	b0382ca167	ipn/ipnlocal: some state_test cleanups. ... This doesn't change the actual functionality. Just some additional comments and fine tuning. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
Avery Pennarun	b7e31ab1a4	ipn: mock controlclient.Client; big ipn.Backend state machine test. ... A very long unit test that verifies the way the controlclient and ipn.Backend interact. This is a giant sequential test of the state machine. The test passes, but only because it's asserting all the wrong behaviour. I marked all the behaviour I think is wrong with BUG comments, and several additional test opportunities with TODO. Note: the new test supercedes TestStartsInNeedsLoginState, which was checking for incorrect behaviour (although the new test still checks for the same incorrect behaviour) and assumed .Start() would converge before returning, which it happens to do, but only for this very specific case, for the current implementation. You're supposed to wait for the notifications. Updates: tailscale/corp#1660 Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
