nacl-amd64p32 builder running (and failig)

[Brad Fitzpatrick]

The nacl-amd64p32 builder is now running.

Here's it failing:

    http://build.golang.org/log/7006e1791aad742f6c321e30985e80e5b9d5ab41

[Brad Fitzpatrick]

And there's me failing to type in the subject.

[Rémy Oudompheng]

It should use GOHOSTARCH=amd64 and GOARCH=amd64p32.

[Dave Cheney]

From memory the builder always sets GOHOSTARCH etc, in this case it shouldn't. 

[Brad Fitzpatrick]

Yes, to be clear I'm only using the builder:

builder -v linux-amd64 linux-386 nacl-amd64p32

[Dave Cheney]

I was the one that added the GOHOSTOS/ARCH=GOOS/ARCH bit to the
builder a while back when we found out that builders were actually
doing cross compiles on linux and darwin for 386.

Let me take a crack at modifying this behaviour.

[Brad Fitzpatrick]

I don't remember that change.

If it was recent, it's possible the Linux builder binary is old.

[Brad Fitzpatrick]

Current manual build, on a different (but ~identical) linux-amd64 machine:

ante:src $ PATH=$HOME/nacl:$PATH GOOS=nacl GOHOSTARCH=amd64 GOARCH=amd64p32 ./all.bash

Known?

How far is it expected to get currently?

Know error. I proposed a CL to add the fake time support
(runtime.timens is the switch to turn it off/on) but it was too
invasive so was dropped. rsc suggested just merging the bit that
defines the symbol as 0. I'll do that this morning

https://codereview.appspot.com/72790043, needs a second LGTM.

> compress/lzw

[Dave Cheney]

https://codereview.appspot.com/74220043/ fixes the missing
runtime.timens symbol. Fake time is not finished, so is disabled.

With this ./make.bash finishes on darwin/amd64, I'm assuming
linux/amd64 as well.

[Dave Cheney]

Hi Brad,

Could you please try this small change to the builder. Hopefully the
accompanying comment will explain what is going on.

https://codereview.appspot.com/74230043

[Brad Fitzpatrick]

Done.

ac22f24159cc path/filepath: fixed misaligned comment will now build with the updated + patched builder.  It was running a builder from July of last year, before the builder moved to the go.tools subrepo.

[Dave Cheney]

Awesome, I'll mail out that change.

Are you going to setup nacl/386 as well ?

[Rémy Oudompheng]

Do you know why the nacl/386 shows so many segfaults ?
Like http://build.golang.org/log/0e69b744b9df0b7ccd83c41bf09209d6c29f1730

It says:

ok hash/adler32 0.053s
ok hash/crc32 0.036s

** Signal 11 from untrusted code: pc=49012
FAIL hash/crc64 0.037s

On my machine I don't have an issue at all:

% GOARCH=386 GOOS=nacl bin/go test hash/crc64
ok hash/crc64 0.028s
% GOARCH=386 GOOS=nacl bin/go test -short hash/crc64
ok hash/crc64 0.028s

Is it using the correctl NaCl loader ?

Rémy.

I thought I just copied what Russ wrote and said to do.

Here's what the builder's got, with this directory in the builder's $PATH:
