nixos/test-driver: Allow interactive testing on Wayland-only setups
On my system I have XWayland disabled and therefore only WAYLAND_DISPLAY
is set. This ensures that the graphical output will still be enabled on
such setups (both Wayland and X11 are supported by the viewer).

Luke Granger-Brown 4de343cccf nixos/test-driver: use a variety of different Tesseract settings for OCR
When performing OCR, some of the Tesseract settings perform better than
others on a variety of different workloads, but they mostly take
~negligible incremental time to run compared to the overhead of running
the ImageMagick filters.

After this commit, we try using all three of the current Tesseract
models (classic, LSTM, and classic+LSTM) to generate output text. This
fixes chromium-90's tests at release-20.09, and should make cases where
you're looking for *specific* text better, with the tradeoff of running
Tesseract multiple times.

To make it sensible to cherrypick this into release-20.09, this doesn't
change the existing API surface for the test driver. In particular,
get_screen_text continues to have the existing behaviour.

Frederik Rietdijk f36b838e2a nixos test-driver: fix single line docstrings, fixes #104467

It seems support for this landed in the latest version of Black.

Konrad Borowski 254d30d4c9 test-driver.py: remove bufsize=1 from Popen calls
According to Python documentation [0], `bufsize=1` is only meaningful in
text mode. As we don't pass in an argument called `universal_newlines`,
`encoding`, `errors` or `text` the file objects aren't opened in text
mode, which means the argument is ignored with a warning in Python 3.8.

    line buffering (buffering=1) isn't supported in binary mode,
    the default buffer size will be used

This commit removes this warning that appared when using
interactive test driver built with `-A driver`. This is done by
removing `bufsize=1` from Popen calls.

The default parameter when unspecified for `bufsize` is `-1` which
according to the documentation will be interpreted as
`io.DEFAULT_BUFFER_SIZE`. As mentioned by a warning, Python already
uses default buffer size when providing `buffering=1` parameter for
file objects not opened in text mode.

test-driver.py: defaulting keepVmState in Machine init
ecb73fd555 introduced a new keepVmState
CLI flag for test-driver.py. This CLI flags gets forwarded to the
Machine class through create_machine.

It created a regression for the boot tests where __main__ end up not
being evaluated. See
https://github.com/NixOS/nixpkgs/pull/97346#issuecomment-690951837 for
bug report.

Defaulting keepVmState to false when __main__ ends up not being
evaluated.

test-driver.py: fix VM state directory deletion
The previous version of the code would only kick in if the state
directory path pointed at a *file*, which never occurs. Making that
codepath actually work reveals an ordering bug, which this patch fixes
as well.

It also replaces the confusing, imperative case log message "delete VM
state directory" with "deleting VM state directory".

Finally, we hint the user about how to prevent this deletion. IE. by
passing the --keep-vm-state flag.

Bug report:
https://github.com/NixOS/nixpkgs/pull/91046#issuecomment-685568750

nixos/test-driver: Use guest time when using sleep
With the Perl driver, machine.sleep(N) was doing a sleep on the guest
machine instead of the host machine. The new Python test driver however
uses time.sleep(), which instead sleeps on the host.

While this shouldn't make a difference most of the time, it *does*
however make a huge difference if the test machine is loaded and you're
sleeping for a minimum duration of eg. an animation.

I stumbled on this while porting most of all my tests to the new Python
test driver and particularily my video game tests failed on a fairly
loaded machine, whereas they don't with the Perl test driver.

Switching the sleep() method to sleep on the guest instead of the host
fixes this.

test-driver.py: delete VM state directory after test run
Keeping the VM state test across several run sometimes lead to subtle
and hard to spot errors in practice. We delete the VM state which
contains (among other things) the qcow volume.

We also introduce a -K (--keep-vm-state) flag making VM state to
persist after the test run. This flag makes test-driver.py to match
its previous behaviour.

qemu-vm: fix inconsistent caching of xchg dirs
xchg is advertised as a bidirectional exchange dir, but file content
transfer from host to VM fails due to caching:
If a file is read in the VM and then modified on the host, subsequent
re-reads in the VM can yield old, cached data.
This is caused by the use of 9p's cache=loose mode that is explicitly
meant for read-only mounts.

9p doesn't provide any suitable cache modes, so fix this by disabling
caching.

Also, remove a now unnecessary sync in the test driver.

test-driver: remove useless syncs
These syncs have the goal to transfer host filesystem changes to the VM,
but they have no effect because 1) syncing in the VM can't possibly pull
in host data and 2) 9p is accessing the host filesystem on the cached
layer anyways, so even syncing on the host would have no effect in the
VM.

The test harness provides the commands it wishes to run in Bourne

with fish:

Eelco Dolstra 78f2a83029 test-driver.py: Fix deadlock when the log queue gets full
If a program (e.g. nixos-install) writes more than 1000 lines to
stderr during execute(), then process_serial_output() deadlocks
waiting for the queue to be processed. So use an unbounded queue
instead.

We should probably get rid of the structured log output (log.xml),
since then we don't need the log queue anymore.

Erik Arvstedt 5bdb653baf test-driver.py: fix decoding of VM output
The codec format 'unicode_escape' was introduced in 52ee102 to handle
undecodable bytes in boot menus.

This made the problem worse as unicode chars outside of iso-8859-1
produce garbled output and valid utf-8 strings (such as "\x" ) trigger
decoding errors.

Fix this by using the default 'utf-8' codec and by explicitly ignoring
decoding errors.

Eric Culp 21f567bdd9 test-driver.py: Share the shared dir between VMs
This changes the python test driver to match the behavior of the perl

same for all machines.

This probably fixes many tests, but I found this while investigating
failures in nixos/tests/ceph-multi-node.nix.
