+ add a test for parseAndRemoveLogLevel() + add a test for drainPendingMessages() + test JSON log encoding including several special cases Other tests frequently send logs but a) don't check the result and b) do so by happenstance, such that the code in encode() was not consistently being exercised and leading to spurious changes in code coverage. These tests attempt to more systematically test the logging function. This is the second attempt to add these tests, the first attempt (in https://github.com/tailscale/tailscale/pull/1114) had two issues: 1. httptest.NewServer creates multiple goroutine handlers, and logtail uses goroutines to upload, but the first version had no locking in the server to guard this. Moved data handling into channels to get synchronization. 2. The channel to notify the test of the arrival of data had a depth of 1, in cases where the Logger sent multiple uploads it would block the server. This resulted in the first iteration of these tests being flaky, and we reverted it. This new version of the tests has passed with go test -race -count=10000 and seems solid.

Tailscale
Private WireGuard® networks made easy
Overview
This repository contains all the open source Tailscale client code and
the tailscaled daemon and tailscale CLI tool. The tailscaled
daemon runs primarily on Linux; it also works to varying degrees on
FreeBSD, OpenBSD, Darwin, and Windows.
The Android app is at https://github.com/tailscale/tailscale-android
Using
We serve packages for a variety of distros at https://pkgs.tailscale.com .
Other clients
The macOS, iOS, and Windows clients use the code in this repository but additionally include small GUI wrappers that are not open source.
Building
go install tailscale.com/cmd/tailscale{,d}
If you're packaging Tailscale for distribution, use build_dist.sh
instead, to burn commit IDs and version info into the binaries:
./build_dist.sh tailscale.com/cmd/tailscale
./build_dist.sh tailscale.com/cmd/tailscaled
If your distro has conventions that preclude the use of
build_dist.sh, please do the equivalent of what it does in your
distro's way, so that bug reports contain useful version information.
We only guarantee to support the latest Go release and any Go beta or release candidate builds (currently Go 1.15) in module mode. It might work in earlier Go versions or in GOPATH mode, but we're making no effort to keep those working.
Bugs
Please file any issues about this code or the hosted service on the issue tracker.
