Description Dan Horák 2016-10-13 16:18:59 UTC 
test_os started to fail with the latest python3 build on s390x, the difference to previous (successful) build might be the builders are now F-24 based, the difference to primary builders is that we use XFS for root fs

Comment 1 Charalampos Stratakis 2016-10-13 19:18:41 UTC 
Hmm this is weird.

An upstream patch [0] from 3.5.3 was backported to python3 in rawhide in order to fix a FTBFS with the rebased OpenSSL 1.1.0. (Basically to make the ssl and hashlib python modules OpenSSL 1.1.0 compatible)

Latest release is python3-3.5.2-6.fc26 though, where I made some minor fixes related to that, I tried a scratch build but it still fails with the same error: [1]

In rawhide however python 3.6 will be deployed soon(ish) so I tried to build the 3.6 beta 2, which fails with a different error so I guess it would be better to debug that one [2]

Will try to find some time next week for it.

Comment 2 Dan Horák 2016-10-14 21:39:38 UTC 
I run few more tests by rebuilding the python3-3.5.2-5.fc26 source rpm on a F-24 based machines (ext4 and xfs root fs) using
mock -r fedora-rawhide-s390x python3-3.5.2-5.fc26.src.rpm
(all that is close how the s390 koji build environment looks) and the results are
 - ext4 passes with kernel 4.7.3-200.fc24.s390x
 - xfs  passes with kernel 4.6.4-301.fc24.s390x
        fails  with kernel 4.7.3-200.fc24.s390x

Is it possible to prepare a standalone test case that could the XFS filesystem devels use to analyse the issue? The problem is rather in XFS in kernel than in python.
Comment 3 Dan Horák 2016-10-17 08:43:11 UTC 
few more results
s390x xfs
           fails  with kernel 4.8.1-1.fc25.s390x
           fails  with kernel 4.8.0-0.rc7.git3.1.fc26.s390x (local rebuild on f26)

ppc64 xfs passes with kernel 4.5.5-300.fc24.ppc64
          fails  with kernel 4.7.4-200.fc24.ppc64

=> (my conclusion) something broke in XFS extended attributes on big endians (only?) between kernel 4.6 and 4.7

the Python code reproducing the failure is

        many = sorted("user.test{}".format(i) for i in range(100))
        for thing in many:
            setxattr(fn, thing, b"x", **kwargs)
        self.assertEqual(set(listxattr(fn)), set(init_xattr) | set(many))


Switching to kernel and asking our XFS maintainer for his view.

got same failure with kernel 4.7.7-200.fc24.ppc64le -> shouldn't be endian related
Comment 5 Dan Horák 2016-10-17 10:54:12 UTC 
Created attachment 1211306 [details]
standalone test case

run with "python3 test.py"

when the number in range() is lowered from 100 to 22, the test passes, starting at 23 it fails
Comment 7 Charalampos Stratakis 2016-10-18 09:00:21 UTC 
Maybe it's worth reporting the issue at python's upstream issue tracker.

I believe it's a kernel issue, so likely not worth to bother Python upstream with it.
Comment 9 Dan Horák 2016-10-18 13:45:03 UTC 
when run the test with value 23 in range() - see the "selinux" attribute there

Comment 10 Eric Sandeen 2016-10-18 13:53:30 UTC 
I think this was regressed with

2a6fba6 "xfs: only return -errno or success from attr ->put_listent"

in v4.7, and fixed with

791cc43 Make __xfs_xattr_put_listen preperly report errors.

which will hit 4.9.

Any chance you could retest with the latest rawhide kernel
(i.e. https://kojipkgs.fedoraproject.org/packages/kernel/4.9.0/0.rc1.git0.2.fc26/ ?)

We probably need to get that commit sent to -stable.

thanks,
-Eric

You are right, it's fixed :-)

I've pointed that commit out to the Fedora kernel team.  They'll bring it into the 4.8.y Fedora release kernels until it hits stable.
