bc65ae6961 tests/functional: Move the check for the parameters from avocado to functional
test_x86_64_pc in tests/avocado/boot_linux_console.py only checks
whether the kernel parameters have correctly been passed to the
kernel in the guest by looking for them in the console output of the
guest. Let's move that to the functional test framework now, but
instead of doing it in a separate test, let's do it for all tuxrun
tests instead, so it is done automatically for all targets that have
a tuxrun test.

23686dfb76 tests/functional: remove all class level fields
A number of fields are set at the class level on QemuBaseTest, even
though the exact same named field is then set at the object level
later in most cases.

The 'self.logger' initialization in ACPI bits test needs to be removed
since 'self.log' won't exist at that point in the flow. It already
initialized 'self.logger' later in the setUp() method, so the __init__
method was redundant.

28adad0a4d tests/functional/asset: Add AssetError exception class
Assets are uniquely identified by human-readable-ish url, so make an
AssetError exception class that prints url with error message.

A property 'transient' is used to capture whether the client may retry
or try again later, or if it is a serious and likely permanent error.
This is used to retain the existing behaviour of treating HTTP errors
other than 404 as 'transient' and not causing precache step to fail.
Additionally, partial-downloads and stale asset caches that fail to
resolve after the retry limit are now treated as transient and do not
cause precache step to fail.

For background: The NetBSD archive is, at the time of writing, failing
with short transfer. Retrying the fetch at that position (as wget does)
results in a "503 backend unavailable" error. We would like to get that
error code directly, but I have not found a way to do that with urllib,
so treating the short-copy as a transient failure covers that case (and
seems like a reasonable way to handle it in general).

7524e1b336 tests/functional/asset: Verify downloaded size
If the server provides a Content-Length header, use that to verify the
size of the downloaded file. This catches cases where the connection
terminates early, and gives the opportunity to retry. Without this, the
checksum will likely mismatch and fail without retry.

a5e8299d1a tests/functional/asset: Fail assert fetch when retries are exceeded
Currently the fetch code does not fail gracefully when retry limit is
exceeded, it just falls through the loop with no file, which ends up
hitting other errors.

Add a check for non-existing file, which indicates the retry limit was

9813958892 tests/functional: stop output from zstd command when uncompressing
The zstd command will print incremental decompression progress to stderr
when running. Fortunately it is not on stdout as that would confuse the
TAP parsing, but we should still not have this printed. By switching
from 'check_call' to 'run' with the check=True and capture_output=True
we'll get the desired silence on success, and on failure the raised
exception will automatically include stdout/stderr data for diagnosis
purposes.

let's extract it into the qemu_test module.
Also add  an __enter__ and __exit__ function that can be used for
using this functionality in a locked context, so that tests that
are running in parallel don't try to compete for the same ports
later.
Also make sure to only use ports in the "Dynamic Ports" range
(see https://www.rfc-editor.org/rfc/rfc6335) and "randomize" the
start of the probed range with the PID of the test process to
further avoid possible clashes with other competing processes.

674a750b51 tests/functional: ignore errors when caching assets, except for 404
We see periodic errors caching assets due to a combination of transient
networking and server problems. With the previous patch to skip running
a test when it has missing assets, we can now treat most cache download
errors as non-fatal.

Only HTTP 404 is retained as fatal, since it is a strong indicator of
a fully broken test rather than a transient error.

f84f8e71eb tests/functional: add helpers for building file paths
Add helper methods that construct paths for

 * log files - to be preserved at the end of a test
 * scratch files - to be purged at the end of a test
 * build files - anything relative to the build root
 * data files - anything relative to the functional test source root
 * socket files - a short temporary dir to avoid UNIX socket limits

These are to be used instead of direct access to the self.workdir,
or self.logdir variables, or any other place where paths are built
manually.

The 'which' helper is simpler, not depending on the external 'which'
binary, and is sufficient for test needs.

3ea06d65be tests/functional: introduce some helpful decorators
Reduce repeated boilerplate with some helper decorators:

 @skipIfNotPlatform("x86_64", "aarch64")

  => Skip unless the build host platform matches

 @skipIfMissingCommands("mkisofs", "losetup")

  => Skips unless all listed commands are found in $PATH

 @skipIfMissingImports("numpy", "cv2")

  => Skips unless all listed modules can be imported

 @skipFlakyTest("https://gitlab.com/qemu-project/qemu/-/issues/NNN")

  => Skips unless env var requests flaky tests with the
     reason documented in the referenced gitlab bug

 @skipBigData

  => Skips unless env var permits tests creating big data files

 @skipUntrustedTest

  => Skips unless env var permits tests which are potentially
     dangerous to the host

f5578e427f tests/functional: avoid accessing log_filename on earlier failures
If a failure occurs early in the QemuBaseTest constructor, the
'log_filename' object atttribute may not exist yet. This happens
most notably if the QEMU_TEST_QEMU_BINARY is not set. We can't
initialize 'log_filename' earlier as we use the binary to identify
the architecture which is then used to build the path in which the
logs are stored.

1a8755a51e tests/functional: add a QMP backdoor for debugging stalled tests
Support the QEMU_TEST_QMP_BACKDOOR=backdoor.sock env variable as a
way to get a QMP backdoor for debugging a stalled QEMU test. Most
typically this would be used if running the tests directly:

 $ QEMU_TEST_QMP_BACKDOOR=backdoor.sock \
   QEMU_TEST_QEMU_BINARY=./build/qemu-system-arm \
   PYTHONPATH=./python \
   ./tests/functional/test_arm_tuxrun.py

And then, when the test stalls, in a second shell run:

 $ ./scripts/qmp/qmp-shell backdoor.sock

97d79319f0 tests/functional: remove time.sleep usage from tuxrun tests
The tuxrun tests send a series of strings to the guest to login
and then run commands. Since we have been unable to match on
console output that isn't followed by a newline, the test used
many time.sleep() statements to pretend to synchronize with
the guest.

This has proved to be unreliable for the aarch64be instance of
the tuxrun tests, with the test often hanging. The hang is a
very subtle timing problem, and it is suspected that some
(otherwise apparently harmless) I/O error messages could be
resulting in full FIFO buffers, stalling interaction with
the guest.

With the newly rewritten console interaction able to match
strings that don't have a following newline, the tux run
tests can now match directly on the login prompt, and/or
shell PS1 prompt.
