runtime: failed build, compile and use compiled binary on macOS Sierra Beta 4(16A270f)

[zchee]

At first, I'm not good at English. If you can't understand, please point out.

1 . What version of Go are you using (go version)?
go version devel +f575873 Tue Aug 2 01:58:14 2016 +0000 darwin/amd64

2 . What operating system and processor architecture are you using (go env)?

GOARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GOOS="darwin"
GOPATH="/Users/zchee/go"

3 . What did you do?
On macOS Sierra Beta 4(16A270f), all of the go compiled tools can not be used.
Broken go runtime on Sierra again :(

It's related upgrade of macOS kernel to Beta 4, also there is no direct relationship to Xcode and Command Line Tools.
It is certainly. Because I know way of the downgrade to macOS kernel and I had tested.

Also, now my kernel version is the downgrade to Beta3 (16A254g).
but If you want to more debug, I can try to upgrade again and any debugging.

---

The error log is described below. Please click to ▶︎.

First and second is building go binary use ./make.bash.
Second is set GODEBUG=gctrace=1,schedtrace=100,scheddetail=1 because suggests at #16272 (comment). But maybe it's for __commpage_gettimeofday?
If so, and if you want to more debug log with other flags, Please feel free to instruct.

./all.bash also fail in the same way, so does not put it.

That result will occur runtime.MSpanList_Insert error and more.

env:

• $GOROOT_BOOTSTRAP=/usr/local/bootstrap/go/go1.4.3

Next is compiling package, e.g. gb.

env:

• $GOROOT=/usr/local/bootstrap/go/go1.7rc3
  • Because /usr/local/go/bin/go was broken.
• which clang:
  • /Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang

or

fatal error: systemstack called from unexpected goroutine

I don't know why to occur that error and go runtime source, but I think related goroutine.
Because If does not use the goroutine (than main) cli tool, does not occur. such as gotype.

4 . What did you expect?
Build the go binary to complete successfully, also package.
and use go compiled tools successfully.

5 . What did you see instead?
build, compile, use cli.

Oh, I forgot.

If that problem was the macOS feature specification rather than a macOS's bug, I think the very impact issue.
I do not know whether it is difficult to fix this, However, It does not work anything.

[bradfitz]

From an email thread,

Beta 4 of macOS 10.12 may subtly break Go's gettimeofday(2) stub again.

% lldb /usr/lib/system/libsystem_kernel.dylib
(lldb) disas -n __gettimeofday
libsystem_kernel.dylib`__gettimeofday:
libsystem_kernel.dylib[0x195d9] <+0>:  movq   $0x0, %rdx
libsystem_kernel.dylib[0x195e0] <+7>:  movl   $0x2000074, %eax
libsystem_kernel.dylib[0x195e5] <+12>: movq   %rcx, %r10
libsystem_kernel.dylib[0x195e8] <+15>: syscall 

Zero’ing the third argument is a change from earlier betas. It’s now used to specify an address where we will copy-out an additional value, so if it contains garbage it may corrupt the memory at that address.

@zchee, thanks for confirming that it does indeed break things.

It's at least harmless for me on OS X 10.11.

@bradfitz Thanks! oh, it's known issue :)
Sorry for I'm not checked email thread.

Now tested that patch only ./make.bash, but results will same... :(

[bradfitz]

@zchee, no, my fault probably. We'll take a look tomorrow. Thanks for the report and for trying that patch.

[zchee]

@bradfitz I got it. Thanks :)
I will try to more debug use llvm, will reports if I find something.

and FYI, I have macOS Sierra Beta1 ~ Beta4 upgrade pkg, also expanded included file to flatten directory.
If you want to disassemble any dylib information, I can offer that data per each Beta version to the Go core members.

[sekimura]

It's true that there are some changes in gettimeofday but is this related to runtime.systime in sys_darwin_amd64.s fixed in #16272 ? I wonder if it's about runtime.switchtoM in asm_amd64.s according to the error messages.

[zchee]

@sekimura I think so, too. It's have not to the related of _gettimeofday in the error log.

As @bradfitz says, surely libsystem_kernel.dylib has been changed, but It does not hit those that related to _gettimeofday in the lldb output.

I cannot read .s and not familiar with lldb, but I think maybe the different issue from the _gettimeofday.

[zchee]

This may not be relevant...
but I found new __gettimeofday_with_mach on the /usr/local/lib/libsystem_kernel.dylib from the Beta4.
Beta3's libsystem_kernel.dylib has not that syscall.

I don't know where to use. but just to be sure, post the those disassemble results.

@zchee the error you are reporting is coming from the Go 1.4 distribution you are using. (Note the first position listed in the stack trace, /usr/local/go/src/runtime/mheap.c:692.)

If you are applying @bradfitz's patch to your GOROOT, it won't fix the error you are seeing because the 1.4 binary is already built and not being rebuilt.

Do you have another machine not running Beta4? If so, could you please:

1. Apply the patch on the other machine.
2. Build a Go installation.
3. Copy the Go installation to the machine with Beta4.
4. Use the new copy of Go as GOROOT_BOOTSTRAP.

If you don't have another machine I could build you a patched Go release and put it somewhere for you to download.
