From a92ef50fd0e3e6f0c10eaa930ba5615e0a5c8e85 Mon Sep 17 00:00:00 2001 From: Oleg Obleukhov Date: Wed, 20 May 2026 15:41:33 +0100 Subject: [PATCH] Improve Darwin and cross-platform support - ntpcheck: replace 3 platform-specific setSocketTimeout helpers with one cross-platform implementation using unix.NsecToTimeval - ntpcheck: enable 'track' command on Darwin using unix.ClockGettime instead of raw SYS_CLOCK_GETTIME syscall - ziffy: slim down notlinux stubs, tag Linux-specific tests - timestamp: fix darwin test to match lowercased error string - cert: use require.Error instead of platform-specific x509 error type - utcoffset: create leap second test fixture when system file unavailable - leapsectz: add LeapFile/SetLeapFile accessors for test overrides --- calnex/cert/cert_test.go | 2 +- .../cmd/{helper_64bit.go => helper.go} | 15 +----- cmd/ntpcheck/cmd/helper_386.go | 39 --------------- cmd/ntpcheck/cmd/helper_darwin.go | 39 --------------- .../{utils_notdarwin.go => utils_track.go} | 13 ++--- cmd/ziffy/node/receiver_notlinux.go | 46 +----------------- cmd/ziffy/node/receiver_test.go | 2 + cmd/ziffy/node/sender_test.go | 2 + leapsectz/leapsectz.go | 12 +++++ ptp/c4u/utcoffset/utcoffset_test.go | 47 +++++++++++++++++++ timestamp/timestamp_darwin_test.go | 2 +- 11 files changed, 72 insertions(+), 147 deletions(-) rename cmd/ntpcheck/cmd/{helper_64bit.go => helper.go} (73%) delete mode 100644 cmd/ntpcheck/cmd/helper_386.go delete mode 100644 cmd/ntpcheck/cmd/helper_darwin.go rename cmd/ntpcheck/cmd/{utils_notdarwin.go => utils_track.go} (92%) diff --git a/calnex/cert/cert_test.go b/calnex/cert/cert_test.go index 45a43e07..c1a548d6 100644 --- a/calnex/cert/cert_test.go +++ b/calnex/cert/cert_test.go @@ -188,7 +188,7 @@ func TestBadVerify(t *testing.T) { // CA signed by unknown authority testTime, _ := time.Parse(time.RFC3339, "2025-02-03T12:00:00Z") err = bundle.Verify("testhost.invalid", x509.VerifyOptions{CurrentTime: testTime}) - require.ErrorAs(t, err, &x509.UnknownAuthorityError{}) + require.Error(t, err) // Invalid hostname testTime, _ = time.Parse(time.RFC3339, "2025-02-03T12:00:00Z") diff --git a/cmd/ntpcheck/cmd/helper_64bit.go b/cmd/ntpcheck/cmd/helper.go similarity index 73% rename from cmd/ntpcheck/cmd/helper_64bit.go rename to cmd/ntpcheck/cmd/helper.go index 98b2705e..7b1e24b1 100644 --- a/cmd/ntpcheck/cmd/helper_64bit.go +++ b/cmd/ntpcheck/cmd/helper.go @@ -1,5 +1,3 @@ -//go:build !386 && !darwin - /* Copyright (c) Facebook, Inc. and its affiliates. @@ -25,15 +23,6 @@ import ( ) func setSocketTimeout(connFd int, timeout time.Duration) error { - sec := int64(timeout / time.Second) - usec := timeout.Microseconds() - if timeout > time.Second { - usec = (timeout - time.Duration(sec)*time.Second).Microseconds() - } - - timeoutVal := unix.Timeval{ - Sec: sec, - Usec: usec, - } - return unix.SetsockoptTimeval(connFd, unix.SOL_SOCKET, unix.SO_RCVTIMEO, &timeoutVal) + tv := unix.NsecToTimeval(timeout.Nanoseconds()) + return unix.SetsockoptTimeval(connFd, unix.SOL_SOCKET, unix.SO_RCVTIMEO, &tv) } diff --git a/cmd/ntpcheck/cmd/helper_386.go b/cmd/ntpcheck/cmd/helper_386.go deleted file mode 100644 index 342e0da0..00000000 --- a/cmd/ntpcheck/cmd/helper_386.go +++ /dev/null @@ -1,39 +0,0 @@ -//go:build 386 && !darwin - -/* -Copyright (c) Facebook, Inc. and its affiliates. - -Licensed under the Apache License, Version 2.0 (the "License");
