0.6 is around the corner!

0.6 is around the corner!

[Ludovic Courtès]

Hello,

0.6 is getting ready!  The remaining items are Mark’s new union.scm, and
Nikita’s signed-substitutes support.
  
I think we can expect to have them in shape within a few days, hopefully.
So it’s definitely time to report any issues you may have.

Comments welcome!

I've run into a build issue with recent master on x86_64 and Loongson 3A
(both hosted on Debian wheezy).  Python 3 fails in the tests with
"OSError: out of pty devices" and then the guix-daemon sometimes gets
stuck in a sleeping state and hangs indefinitely.

My Loongson 2F system, based on 1eefbb2693f0f29f8f095af9f067240b85e735aa
with some cherry-picks and local patches, did not run into this problem.
My guess is that a commit since 1eefbb2 broke things.  Alternatively,
maybe the difference is that my Loongson 2F is not based on Debian, but
rather on my home-built custom system based on CLFS.

For completeness, here are the patches I added to 1eefbb2, so the
problem isn't in any of these:

--8<---------------cut here---------------start------------->8---
727c3ed * [mhw] gnu: pulseaudio: Increase timeouts for tests.

  pth, bazaar, ocaml, indent, netpbm.

* Look into security updates for mutt, file, and libssh:

Actually, the reason it worked on my Loongson 2F is that the Python 3
tests weren't run at all.  They've been enabled since then.

On the subject of things I want to get into 0.6, I forgot these:

> a44bec8 * PRELIMINARY Upgrade sqlite to 3.8.4, and apply large page size fix.

Dan Kennedy, who I guess is an sqlite dev, gave me a patch to fix the
problems with sqlite on systems with 64K pages, such as my YeeLoong.
I'd like to get this in, along with an upgrade to 3.8.4, or 3.8.4.1 if
it's on the sourceforge mirror now (it wasn't the last time I checked).

> b749814 * TEMPORARY HACK: Disable tests for gdb.

gdb-7.7 seems to work for me, but the test suite consistently fails for
me on MIPS, and apparently also i686 judging from hydra, last I checked.

The problem is that there are always tests in GDB’s test suite that may
fail on some platform, and I don’t really know how we’re supposed to
interpret that (well, I haven’t investigated.)

Any idea what this test is doing?  (Maybe Cyril knows?)

How does that happen?  Could you get a backtrace next time it shows up,
and ideally a way to reproduce?

One candidate is 9a9a3ad (“Enable tests in Python 3.”).

Definitely.  The last draft you posted looked OK to me; I can write test
sometime before or after you push it.

OK, but that shouldn’t be blocking.

Yes, makes sense.  Thanks for keeping track of that!

Cyril is apparently unable to reproduce the problem on his system, which
he tells me is Debian Sid running in a VM.

Eric Bavier reported seeing the same problem on x86_64 Trisquel 6.0.

See below for the tail of my build log.

This particular test is fixed by the daemon patch I posted, which makes
sure /dev/pts/ptmx is 0666 (I’ll update nix-upstream.)

Now I see one remaining failure:

It doesn’t help, though.

What are the security implications of this?  Why do you suppose that
Debian (or Linux, the kernel?) uses perms 0000 for /dev/pts/ptmx, and
how it is that these tests normally work outside of guix-daemon, when
the perms are 0000?

The devpts file system of Linux creates this file with perms 000 by
default:

  https://www.kernel.org/doc/Documentation/filesystems/devpts.txt

> and how it is that these tests normally work outside of guix-daemon,

Often, outside the chroot, /dev/ptmx is directly a character device,
with perms 0666.  Conversely, inside the chroot it’s a symlink to
/dev/pts/ptmx (as suggested in devpts.txt), but until this patch was
applied, it had perms 000.

Re: 0.6 is around the corner!

Looks like the important things are in place.  We still need to do
something about Python 3’s failing test (Cyril?).  I was also thinking
of preparing a QEMU image with X.

I’d like to push the release by Wednesday, so please test, and let’s fix
packages that fail to build!

I suppose that these are genuine bugs in the ctypes module for MIPS.

I've tested this on the Loongson 3A machine, and it works as expected.

    Thanks!

What does 'python -c "import platform; print(platform.machine())"' 
return on your machine ? The tests that fail are now disabled on mips64.

‘mips64’.

I ran ‘make clean’ & co., rebuilt Python; and the tests succeeded.

Thanks!

What would you think of pushing an upgrade to 3.3.5 at the same time?

(Plus a MIPS fix or workaround, which Mark is looking at.)
