From md at linux.it Tue Jul 7 23:41:23 2026 From: md at linux.it (Marco d'Itri) Date: Wed, 8 Jul 2026 01:41:23 +0200 Subject: random tests failing on s390x Message-ID: Random tests (t02014.vtc, c00046.vtc, t02016.vtc) are failing on the Debian s390x build infrastructure: https://buildd.debian.org/status/logs.php?pkg=vinyl-cache&arch=s390x Is this caused by the s390x build daemons being overloaded? The page shows that building the package takes 2m without tests and over 20m with tests. Tests are run on all builds, but only considered on the official 64 bit ports: amd64, arm64, loong64, ppc64el, s390x, except for riscv64 which is currently too slow (and indeed some tests are failing there as well). Is this something that can be worked around, either upstream or in the Debian package, or should I disable the test suite on s390x? -- ciao, Marco -------------- next part -------------- A non-text attachment was scrubbed...

That's my conclusion. We also have a s390x instance in our own "vtest": https://vinyl-cache.org/vtest/ and it shows similar random lossage, even though we run that platform with VTEST_DURATION=180 That said, some of our test-cases are more sensitive to timing than others, and we try to improve that where we can, and I recoginize the cases you mention as being on my personal "trouble-list". We have discussed if some tests should be "advisory", in the sense that a failure is just a "warning" not an "error", but that feels too much like giving up :-) > Is this something that can be worked around, either upstream or in the > Debian package, or should I disable the test suite on s390x? I would disable tests on s390x. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk at FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
