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: https://github.com/moby/moby/commit/f8aef6a92f5961f2615ada37b7d108774a0821e0 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: https://github.com/moby/moby/blob/8e610b2b55bfd1bfa9436ab110d311f5e8a74dcb/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; https://github.com/moby/moby/blob/f1b5612f2008827fdcf838abb4539064c682181e/daemon/kill.go#L40-L48 - Windows only looks to support 2 signals currently https://github.com/moby/moby/blob/8e610b2b55bfd1bfa9436ab110d311f5e8a74dcb/pkg/signal/signal_windows.go#L17-L26 - Upstream Golang looks to define `SIGINT` as well; https://github.com/golang/go/blob/77f9b2728eb08456899e6500328e00ec4829dddf/src/runtime/defs_windows.go#L44 - This looks like the current list of Signals upstream in Go; https://github.com/golang/sys/blob/3b58ed4ad3395d483fc92d5d14123ce2c3581fec/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) ) ``` Signed-off-by: Sebastiaan van Stijn <github@gone.nl> (cherry picked from commit eeaa0b30d47e6b9dac8d8ea2ced6d5ce44c24463) Signed-off-by: Dani Louca <dani.louca@docker.com> Upstream-commit: f481d4c02366093b337e9aebfbbf23b1ff3968fe Component: engine
