Brad Fitzpatrick	db2f37d7c6	ipn/ipnlocal: add some test accessors ... Updates tailscale/corp#12990 Change-Id: I82801ac4c003d2c7e1352c514adb908dbf01be87 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
Brad Fitzpatrick	9538e9f970	ipn/ipnlocal: keep internal map updated of latest Nodes post mutations ... We have some flaky integration tests elsewhere that have no one place to ask about the state of the world. This makes LocalBackend be that place (as it's basically there anyway) but doesn't yet add the ForTest accessor method. This adds a LocalBackend.peers map[NodeID]NodeView that is incrementally updated as mutations arrive. And then we start moving away from using NetMap.Peers at runtime (UpdateStatus no longer uses it now). And remove another copy of NodeView in the LocalBackend nodeByAddr map. Change that to point into b.peers instead. Future changes will then start streaming whole-node-granularity peer change updates to WatchIPNBus clients, tracking statefully per client what each has seen. This will get the GUI clients from receiving less of a JSON storm of updates all the time.

Brad Fitzpatrick	926c990a09	types/netmap: start phasing out Addresses, add GetAddresses method ... NetworkMap.Addresses is redundant with the SelfNode.Addresses. This works towards a TODO to delete NetworkMap.Addresses and replace it with a method. This is similar to #9389.

Brad Fitzpatrick	760b945bc0	ipn/{ipnlocal,ipnstate}: start simplifying UpdateStatus/StatusBuilder ... * Remove unnecessary mutexes (there's no concurrency) * Simplify LocalBackend.UpdateStatus using the StatusBuilder.WantPeers field that was added in 0f604923d3, removing passing around some method values into func args. And then merge two methods. More remains, but this is a start. Updates #9433 Change-Id: Iaf2d7ec6e4e590799f00bae185465a4fd089b822 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago

Brad Fitzpatrick	7c1ed38ab3	ipn/ipnlocal: fix missing controlknobs.Knobs plumbing ... I missed connecting some controlknobs.Knobs pieces in 4e91cf20a8 resulting in that breaking control knobs entirely. Whoops. The fix in ipn/ipnlocal (where it makes a new controlclient) but to atone, I also added integration tests. Those integration tests use a new "tailscale debug control-knobs" which by itself might be useful for future debugging.

Brad Fitzpatrick	42072683d6	control/controlknobs: move ForceBackgroundSTUN to controlknobs.Knobs ...
