Description

Observation

openQA test in scenario OpenQA::Schema::Result::TestSuites=HASH(0xaeb1b28) fails in
bootloader_zkvm

[2019-02-01T10:03:04.876 CET] [debug] Connection to root@s390p8.suse.de established
Calling Net::SSH2::Channel::readline in non-blocking mode is usually a programming error at /usr/lib/os-autoinst/backend/baseclass.pm line 1221.

First time seeing this in Beta2 Candidate of SLE15-SP1, restarting worked though

Workaround

  • restarting the test

Reproducible

Fails since (at least) Build 158.4 (current job)

Expected result

Last good: 157.1 (or more recent)

Further details

Always latest result in this scenario: latest

UPDATE

bootloader_zkvm failures are not related to this warning. This warning comes from perl-Net-SSH2 version 0.66 (commit ad5f9f0 ("Warn about readline being called in non-blocking mode"). I guess 157.1 (last good) also had this warning, just didn't fail due some other reason. I'll fix this issue during fixing #45863.

actually this also occurs in tests which are successful, so it's more a warning

It's possible to debug it if you set debug mode for SSH2: Net::SSH2->new(debug => 1);

Beware it takes a lot data.

@mgriessmeier please always use a team-assignment like [u] or [y]. As you know, we want the teams to be more independant so we should rely less on "catch-all" approaches like people like me to crosscheck the tickets that fall between the silos ;)

BTW I use Net::SSH2::Channel for another serial connection (over nc/virsh console call) for svirt serial terminal in blocking mode in this PR.
https://github.com/os-autoinst/os-autoinst/pull/1109 (#45863)

I hope I'll find a time to address this problematic connection in it as well.

@jlausuch I do not know who added you in that weird way to the projects however I added you now to https://progress.opensuse.org/projects/qa/settings/members as manager so you should be able to do everything yourself now :)

Actually, this must be solved during fixing svirt serial implementation in #45863.

This should be fixed with https://github.com/os-autoinst/os-autoinst/pull/1239 and I haven't seen this log message anymore. Recent tests in the same scenario are not failing anymore, too.
