Bugs in existing tests
Description
Observation¶
Instead of expected redirection to /dev/hvc0, ?DEV?HVC) is typed.
Is sporadic issue
openQA test in scenario sle-12-SP3-Server-DVD-ppc64le-migration_offline_sle12sp2-sdk+allpatterns_fullupdate@ppc64le fails in
patch_before_migration
Reproducible¶
https://openqa.suse.de/tests/958514#step/patch_before_migration/14
Fails since (at least) Build 0400
Expected result¶
In previous run it's different error.
Last good: (unknown) (or more recent)
Further details¶
In the autoinst logs values are correct:
04:36:43.7336 Debug: /var/lib/openqa/cache/openqa.suse.de/tests/sle/tests/update/patch_before_migration.pm:41 called testapi::assert_script_run

Always latest result in this scenario: latest
Maybe related to https://progress.opensuse.org/issues/19194 as on malbec issue doesn't appear

- Subject changed from Shift key pressed during the assert_script_execution call in patch_before_migration on PowerPC to Unstable key presses on PowerPC on QA-Power8-5-kvm worker host
Using single ticket, as multiple failures have same symptoms and most likely same root cause, which is unstable typing which is replicates on QA-Power8-5-kvm, but not on malbec.
In https://progress.opensuse.org/issues/19230 ">" is not typed, which caused "?DEV?HVC)" as shift key was still pressed.
In https://progress.opensuse.org/issues/19266 alt-s combination is used to press "Search" button and then alt key is not released when arrow key is pressed which results in navigation in File menu.
As an experiment we'll try to lower VNC_TYPING_LIMIT value on affected worker to see if it helps.

Nick and I try to fix test runs on QA-Power8-5-kvm and slow down typing speed to see if it helps (see https://progress.opensuse.org/issues/19414) For that we'll hardcode VNC_TYPING_LIMIT variable value in the worker code to get couple of runs. VNC_TYPING_LIMIT value was changed from 10, which is default for PPC to 3.
Where/how did you try and set the typing limit? I cannot see any changes on QA-Power8-5-kvm
Hi Richard,
We've modified /usr/lib/os-autoinst/consoles/vnc_base.pm perl module by changing $seconds_per_keypress variable value. It's the only usage of VNC_TYPING_LIMIT variable we could find in workers code. We did it this way, as it's easiest one and can be easily reverted, as we are not sure if it helps at all. Otherwise we need new machine and new worker class, which is tricky as we already define VNC_TYPING_LIMIT as 10 for all PPC jobs.
Note: these changes could be already reverted with salt, but we got 3 runs yesterday where this "known" issue hasn't taken place.

Oh my..please don't do that sort of hotfixing again..
You could have set VNC_TYPING_LIMIT in the workers.ini via salt
That is what I would have recommended...
I'm actively reverting the hotpatch, as it totally prevents any effort by me to diagnose anything
We've tried to set it in workers.ini manually, but it was not picked up by the worker as is already defined in machine settings. Tried both as global and per worker setting. Anyways, this setting helps pnly when command is typed, but not with unreleased alt/shift keys. Let me know if I can assist you in investigation, as there are around 5 tickets which point us to same issue. I've also created a bug for qemu to get some feedback how we can trace the issue if it's a bug in qemu/kvm.
