This test is failing on Windows currently:
```
11:59:47 --- FAIL: TestHealthKillContainer (8.12s)
11:59:47 health_test.go:57: assertion failed: error is not nil: Error response from daemon: Invalid signal: SIGUSR1
``
That test was added recently in https://github.com/moby/moby/pull/39454, but
rewritten in a commit in the same PR:
f8aef6a92f
In that rewrite, there were some changes:
- originally it was skipped on Windows, but the rewritten test doesn't have that skip:
```go
testRequires(c, DaemonIsLinux) // busybox doesn't work on Windows
```
- the original test used `SIGINT`, but the new one uses `SIGUSR1`
Analysis:
- The Error bubbles up from: 8e610b2b55/pkg/signal/signal.go (L29-L44)
- Interestingly; `ContainerKill` should validate if a signal is valid for the given platform, but somehow we don't hit that part; f1b5612f20/daemon/kill.go (L40-L48)
- Windows only looks to support 2 signals currently 8e610b2b55/pkg/signal/signal_windows.go (L17-L26)
- Upstream Golang looks to define `SIGINT` as well; 77f9b2728e/src/runtime/defs_windows.go (L44)
- This looks like the current list of Signals upstream in Go; 3b58ed4ad3/windows/types_windows.go (L52-L67)
```go
const (
// More invented values for signals
SIGHUP = Signal(0x1)
SIGINT = Signal(0x2)
SIGQUIT = Signal(0x3)
SIGILL = Signal(0x4)
SIGTRAP = Signal(0x5)
SIGABRT = Signal(0x6)
SIGBUS = Signal(0x7)
SIGFPE = Signal(0x8)
SIGKILL = Signal(0x9)
SIGSEGV = Signal(0xb)
SIGPIPE = Signal(0xd)
SIGALRM = Signal(0xe)
SIGTERM = Signal(0xf)
)
