Kevin Wolf 503c2b31b6 iotests.py: Fix type check errors in wait_migration()
Commit 1847a4a8c2 clarified that event_wait() can return None (though
only with timeout=0) and commit f12a282ff4 annotated it as returning
Optional[QMPMessage].

Type checks in wait_migration() fail because of the unexpected optional
return type:

iotests.py:750: error: Value of type variable "Msg" of "log" cannot be "Optional[Dict[str, Any]]"
iotests.py:751: error: Value of type "Optional[Dict[str, Any]]" is not indexable
iotests.py:754: error: Value of type "Optional[Dict[str, Any]]" is not indexable

Fortunately, the non-zero default timeout is used in the event_wait()
call, so we can make mypy happy by just asserting this.

John Snow 090744d552 iotests.py: Adjust HMP kwargs typing
mypy wants to ensure there's consistency between the kwargs arguments
types and any unspecified keyword arguments. In this case, conv_keys is
a bool, but the remaining keys are Any type. Mypy (correctly) infers the
**kwargs type to be **Dict[str, str], which is not compatible with
conv_keys: bool.

Because QMP typing is a little fraught right now anyway, re-type kwargs
to Dict[str, Any] which has the benefit of silencing this check right
now.

A future re-design might type these more aggressively, but this will
give us a baseline to work from with minimal disruption.

(Thanks Kevin Wolf for the debugging assist here)

John Snow 52ea799e96 iotests: use python logging for iotests.log()
We can turn logging on/off globally instead of per-function.

Remove use_log from run_job, and use python logging to turn on
diffable output when we run through a script entry point.

iotest 245 changes output order due to buffering reasons.

An extended note on python logging:

A NullHandler is added to `qemu.iotests` to stop output from being
generated if this code is used as a library without configuring logging.
A NullHandler is only needed at the root, so a duplicate handler is not
needed for `qemu.iotests.diff_io`.

When logging is not configured, messages at the 'WARNING' levels or
above are printed with default settings. The NullHandler stops this from
occurring, which is considered good hygiene for code used as a library.

See https://docs.python.org/3/howto/logging.html#library-config

When logging is actually enabled (always at the behest of an explicit
call by a client script), a root logger is implicitly created at the
root, which allows messages to propagate upwards and be handled/emitted
from the root logger with default settings.

When we want iotest logging, we attach a handler to the
qemu.iotests.diff_io logger and disable propagation to avoid possible
double-printing.

For more information on python logging infrastructure, I highly
recommend downloading the pip package `logging_tree`, which provides
convenient visualizations of the hierarchical logging configuration
under different circumstances.

See https://pypi.org/project/logging_tree/ for more information.

John Snow 239bbcc0ae iotests: add hmp helper with logging
Minor cleanup for HMP functions; helps with line length and consolidates
HMP helpers through one implementation function.

Although we are adding a universal toggle to turn QMP logging on or off,
many existing callers to hmp functions don't expect that output to be
logged, which causes quite a few changes in the test output.

For now, offer a use_log parameter.

Typing notes:

QMPResponse is just an alias for Dict[str, Any]. It holds no special
meanings and it is not a formal subtype of Dict[str, Any]. It is best
thought of as a lexical synonym.

We may well wish to add stricter subtypes in the future for certain
shapes of data that are not formalized as Python objects, at which point
we can simply retire the alias and allow mypy to more strictly check
usages of the name.

John Snow 1cd0dbfc12 iotests: touch up log function signature
Representing nested, recursive data structures in mypy is notoriously
difficult; the best we can reliably do right now is denote the leaf
types as "Any" while describing the general shape of the data.

Regardless, this fully annotates the log() function.

Typing notes:

TypeVar is a Type variable that can optionally be constrained by a
sequence of possible types. This variable is bound to a specific type
per-invocation, like a Generic.

log() behaves as log<Msg>() now, where the incoming type informs the
signature it expects for any filter arguments passed in. If Msg is a
str, then filter should take and return a str.

John Snow 368e062003 iotests: ignore import warnings from pylint
The right way to solve this is to come up with a virtual environment
infrastructure that sets all the paths correctly, and/or to create
installable python modules that can be imported normally.

That's hard, so just silence this error for now.

This doesn't fix everything in here, but it does help clean up the

This should be 100% style changes only; the intent is to make pylint
more useful by working on establishing a baseline for iotests that we
can gate against in the future.

Kevin Wolf fd586ce8be iotests: Filter testfiles out in filter_img_info()
We want to keep TEST_IMG for the full path of the main test image, but
filter_testfiles() must be called for other test images before replacing
other things like the image format because the test directory path could
contain the format as a substring.

Insert a filter_testfiles() call between both.

John Snow 72b2903056 iotests: remove 'linux' from default supported platforms
verify_platform will check an explicit whitelist and blacklist instead.
The default will now be assumed to be allowed to run anywhere.

For tests that do not specify their platforms explicitly, this has the effect of
enabling these tests on non-linux platforms. For tests that always specified
linux explicitly, there is no change.

For Python tests on FreeBSD at least; only seven python tests fail:
045 147 149 169 194 199 211

045 and 149 appear to be misconfigurations,
147 and 194 are the AF_UNIX path too long error,
169 and 199 are bitmap migration bugs, and
211 is a bug that shows up on Linux platforms, too.

This is at least good evidence that these tests are not Linux-only. If
they aren't suitable for other platforms, they should be disabled on a
per-platform basis as appropriate.

Therefore, let's switch these on and deal with the failures.
