[PATCH] tests/avocado: configure acpi-bits to use avocado timeout

[PATCH] tests/avocado: configure acpi-bits to use avocado timeout

[John Snow]

Instead of using a hardcoded timeout, just rely on Avocado's built-in
test case timeout. This helps avoid timeout issues on machines where 60
seconds is not sufficient.

We might want some wait for consoles as well depending on what is output
during the run.

Ah! there's the catch I was forgetting. I subbed this in and it appeared to
work, so I thought I was home free.

OK, back to the drawing board...

actually I think you won't get anything on the console since grub is
not configured to use the serial console.  I tried "-serial stdio" a
while back without any output.

Grub is certainly capable of serial output but I think the grub.cfg
needs changes to support that. It would definitely be an improvement if
we could enable serial output because currently the test is totally mute
while running which is unlike every other test in avocado.

sounds reasonable. bits seems to have its own way to set up grub
serial port redirect and I tried something quickly but it didn't quite
work. Need to spend more time looking at it.

just when I wrote this, it seems my hack finally worked! Will need
more testing before pushing.

I think this is fine. This just waits until the VM is shutdown on its
own and relies on the avocado framework to timeout if it doesn't. We
do not need to look into the console. The test issues a shutdown from
the VM itself once its done with the batch operations.

Alex's critique is valid, though: the way vm.wait() works is to
immediately  terminate the serial console connection as it prepares for the
VM to shut down. I forgot about this.

(For historical reasons, it does this to avoid deadlocks when the pipe
fills.)

I think we definitely do want to make sure we watch the console *while* we
wait for it to shut down, which is not a feature QEMUMachine really offers
right now in a meaningful way.

I need to make some more drastic changes to machine.py, but in the meantime
I can revise this patch to do something a bit smarter so we get console
logging while we wait. This is a use case worth supporting.

(Thanks for writing new and interesting tests!)

Still, if it fails, we want to see the output, right? It's very frustrating
if it doesn't, especially in an automated pipeline.

Maybe  we can push your current patch while we consider these console
logging enhancements for the next release window. Console logging woikd
require some changes in bits and some more testing. I'm not sure if I'll
have time for it immediately at present.

Spoke to John on IRC. Seems this patch using vm.wait() is safe for
this release as I do not use the console o/p in the test and do not
call vm.set_console().
When we enable the console output, some additional work will need to
be done for the QemuMachine library to make sure we avoid races when
we call vm.wait() with _early_cleanup().

Thomas, since you are picking up my other patch, maybe you want to
also pick this one up as well if you have not sent out your PR
already?
