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.

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.

users of VM.wait_migration() to specify the final runstate they desire
and then poll the VM until it has reached that state. (This should be
over very quickly, so busy polling is fine.)
Without this patch, I see intermittent failures in the new iotest 280

maybe they just occur even more rarely, or it is because they also wait

case_notrun() does not actually skip the current test case. It just
adds a "notrun" note and then returns to the caller, who manually has to
skip the test. Generally, skipping a test case is as simple as
returning from the current function, but not always: For example, this
model does not allow skipping tests already in the setUp() function.
Thus, add a QMPTestCase.case_skip() function that invokes case_notrun()
and then self.skipTest(). To make this work, we need to filter the
information on how many test cases were skipped from the unittest
output.

This requires some changes to keep iotests 104 and 207 working.
qemu-img info in 104 will now return a filename including the user name
and the port, which need to be filtered by adjusting REMOTE_TEST_DIR in
common.rc. This additional information has to be marked optional,
however (which is simple as REMOTE_TEST_DIR is a regex), because
otherwise 197 and 215 would fail: They use it (indirectly) to filter
qemu-img create output which contains a backing filename they have
passed to it -- which probably does not contain a user name or port
number.
The problem in 207 is a nice one to have: qemu-img info used to return
json:{} filenames, but with this patch it returns nice plain ones. We
now need to adjust the filtering to hide the user name (and port number
while we are at it). The simplest way to do this is to include both in
iotests.remote_filename() so that bdrv_refresh_filename() will not
change it, and then iotests.img_info_log() will filter it correctly
automatically.

Supported formats listed by 'qemu' may differ from those listed by
'qemu-img' due to whitelists. Some test cases require specific formats
that may be used with qemu. They can be inquired directly by running
'qemu -drive format=help'. The response takes whitelists into account.
The method supported_formats() serves for that. The method decorator
skip_if_unsupported() checks if all requested formats are whitelisted.
If not, the test case will be skipped. That has been implemented in
the 'check' file in the way similar to the 'test notrun' mechanism.

VDI keeps the whole bitmap in memory, and the maximum size (which is
tested here) is 2 GB. This may not be available on all machines, and it
rarely is available when running a 32 bit build.
Fix this by making VM.run_job() return the error string if an error
occurred, and checking whether that contains "Could not allocate bmap"
in 211. If so, the test is skipped.

In some cases, we may want to deal with qemu-nbd errors (e.g. by
launching it in a different configuration until it no longer throws
any). In that case, we do not want its output ending up in the test
output.
It may still be useful for handling the error, though, so add a new
function that works basically like qemu_nbd(), only that it returns the
qemu-nbd output instead of making it end up in the log. In contrast to
qemu_img_pipe(), it does still return the exit code as well, though,
because that is even more important for error handling.

As laid out in the previous commit's message:
```
Several places in iotests deal with serializing objects into JSON
strings, but to add pretty-printing it seems desirable to localize
all of those cases.
log() seems like a good candidate for that centralized behavior.
log() can already serialize json objects, but when it does so,
it assumes filters=[] operates on QMP objects, not strings.
qmp_log currently operates by dumping outgoing and incoming QMP
objects into strings and filtering them assuming that filters=[]
are string filters.
```
Therefore:
Change qmp_log to treat filters as if they're always qmp object filters,
then change the logging call to rely on log()'s ability to serialize QMP
objects, so we're not duplicating that effort.
Add a qmp version of filter_testfiles and adjust the only caller using
it for qmp_log to use the qmp version.

To have qmp_log use log's serialization, qmp_log will need to
accept only qmp filters, not text filters.
However, only a single caller of qmp_log actually requires any
filters at all. I remove the default filter and add it explicitly
to the caller in preparation for refactoring qmp_log to use rich
filters instead.
test 206 is amended to name the filter explicitly and the default

Python before 3.6 does not sort dictionaries (including kwargs).
Therefore, printing QMP objects involves sorting the keys to have
a predictable ordering in the iotests output. This means that
iotests output will sometimes show arguments in an order not
specified by the test author.
Presently, we accomplish this by using json.dumps' sort_keys argument,
where we only serialize the arguments dictionary, but not the command.
However, if we want to pretty-print QMP objects being sent to the
QEMU process, we need to build the entire command before logging it.
Ordinarily, this would then involve "arguments" being sorted above
"execute", which would necessitate a rather ugly and harder-to-read
change to many iotests outputs.
To facilitate pretty-printing AND maintaining predictable output AND
having "arguments" sort after "execute", add a custom sort function
that takes a dictionary and recursively builds an OrderedDict that
maintains the specific key order we wish to see in iotests output.
The qmp_log function uses this to build a QMP object that keeps
"execute" above "arguments", but sorts all keys and keys in any
subdicts in "arguments" lexicographically to maintain consistent
iotests output, with no incompatible changes to any current test.

When dumping an object into the log, there are differences between
Python 2 and 3. First, unicode strings are prefixed by 'u' in Python 2
(they are no longer in 3, because unicode strings are the default
there). Second, the order of keys in dicts may differ. Third,
especially long numbers are longs in Python 2 and thus get an 'L'
suffix, which does not happen in Python 3.
We can get around all of these differences by dumping objects (lists and
dicts) in a language-independent format, namely JSON. The JSON
generator even allows emitting dicts with their keys sorted
alphabetically.
This changes the output of all tests that use these logging functions
(dict keys are ordered now, strings in dicts are now enclosed in double
quotes instead of single quotes, the 'L' suffix of large integers is
dropped, and "true" and "false" are now in lower case).
The quote change necessitates a small change to a filter used in test
207.

Since byte strings are no longer the default in Python 3, we have to
explicitly use them where we need to, which is mostly when working with
structures. It also means that we need to open a file in binary mode
when we want to use structures.
On the other hand, we have to accomodate for the fact that some
functions (still) work with byte strings but we want to use unicode
strings (in Python 3 at least, and it does not matter in Python 2).
This includes base64 encoding, but it is most notable when working with
the subprocess module: Either we set universal_newlines to True so that
the default streams are opened in text mode (hence this parameter is
aliased as "text" as of 3.7), or, if that is not possible, we have to
decode the output to a normal string.

test execution. It is the responsibility of tests to remove any files
they create.
A nice way of doing this is to declare files at the beginning of the
test and automatically remove them with a context manager:
with iotests.FilePath('test.img') as img_path:
qemu_img(...)
qemu_io(...)
# img_path is guaranteed to be deleted here

Test cases 030, 041 and 055 used to sleep for a second after calling
block-job-pause to make sure that the block job had time to actually
get into paused state. We can instead poll its status and use that one
second only as a timeout.
The tests also slept a second for checking that the block jobs don't
make progress while being paused. Half a second is more than enough for
this.
These changes reduce the total time for the three tests by 25 seconds on
my laptop (from 155 seconds to 130).

be None
- The QEMUQtestMachine class constructor needs to use

Running an iotests-based Python test directly might appear to work,
but may fail in subtle ways and is insecure:
- It creates files with predictable file names in a world-writable
location (/var/tmp).
- Tests expect the environment to be set up by check. E.g. 041 and 055
may take the wrong code paths if QEMU_DEFAULT_MACHINE is not
set. This can lead to false negatives.
Instead fail hard and tell the user we want to be run via "check".
The actual environment expected by the tests is currently only defined
by the implementation of "check". We use two of the environment
variables set by "check" as indication of whether we're being run via
"check". Anyone writing their own test runner (replacing "check") will
need to replicate the full environment (in a broader sense, not just
environment variables) provided by "check" anyway, including setting
the two environment variables we check. Whereas a regular developer
just trying to invoke the tests usually won't have both of these
defined in their environment so we can catch their mistake and give
out useful advice.

The names used by iotests are highly prone to name collisions, so
importing them all unconditionally is a bad idea anyway. Since __all__

qemu-iotests test case 148 already had some code for skipping the test
if quorum support is missing, but it didn't work in all
cases. TestQuorumEvents.setUp() gets run before the actual test class
(which contains the skipping code) and tries to start qemu with a drive
using the quorum driver. For some reason this works fine when using
qcow2, but fails for raw.
As the entire test case requires quorum, just check for availability

When testing a topic branch, it's possible that a bug introduced by a
code change makes the python test case hang, with debug output, it is
much easier to locate the problem.
This can also be helpful if you want to watch the progress of a python
test, it offers you a way to sense the speed of each test case method
you're writing.
Note: because there is no easy way to get *both* the verbose output and
the output expected by ./check comparison, the case would always fail
with an "output mismatch". The sole purpose of using this option is

will no longer directly depend on the size of the block device;
therefore, drop these checks from this test. Instead, just check whether
the final offset equals the block job length.
As 041 uses the wait_until_completed function from iotests.py, the same
applies there as well which in turn affects tests 030, 055 and 056. On
the other hand, a block job's length does not have to be related to the

in that out-of-tree build should be supported as well. To do so, a

a symlink, and if so, will assume it is run in the build tree. All
output and temporary operations performed by iotests are then redirected
here and, unless specified otherwise by the user, QEMU_PROG etc. will be
set to paths appropriate for the build tree.
Also, drop making every test case executable if it is not yet, as this
