2022-04-25iotests/163: Fix broken qemu-io invocationJohn Snow
The 'read' commands to qemu-io were malformed, and this invocation only worked by coincidence because the error messages were identical. Oops. There's no point in checking the patterning of the reference image, so just check the empty image by itself instead. (Note: as of this commit, nothing actually enforces that this command completes successfully, but a forthcoming commit in this series will enforce that qemu_io() must have a zero status code.)

2022-03-22iotests: Remove explicit checks for qemu_img() == 0John Snow
qemu_img() returning zero ought to be the rule, not the exception. Remove all explicit checks against the condition in preparation for making non-zero returns an Exception.

2022-02-01iotests: specify some unsupported_imgopts for python iotestsVladimir Sementsov-Ogievskiy
We are going to support IMGOPTS for python iotests. Still some iotests will not work with common IMGOPTS used with bash iotests like specifying refcount_bits and compat qcow2 options. So we should define corresponding unsupported_imgopts for now.

2019-10-04iotests: Remove Python 2 compatibility codeKevin Wolf
Some scripts check the Python version number and have two code paths to accomodate both Python 2 and 3. Remove the code specific to Python 2 and assert the minimum version of 3.6 instead (check skips Python tests in this case, so the assertion would only ever trigger if a Python script is executed manually).

2019-09-10iotests: Restrict file Python tests to fileMax Reitz
Most of our Python unittest-style tests only support the file protocol. You can run them with any other protocol, but the test will simply ignore your choice and use file anyway. We should let them signal that they require the file protocol so they are skipped when you want to test some other protocol.

2018-10-30iotests: Different iterator behavior in Python 3Max Reitz
In Python 3, several functions now return iterators instead of lists. This includes range(), items(), map(), and filter(). This means that if we really want a list, we have to wrap those instances with list(). But then again, the two instances where this is the case for map() and filter(), there are shorter expressions which work without either function. On the other hand, sometimes we do just want an iterator, in which case we have sometimes used xrange() and iteritems() which no longer exist in Python 3. Just change these calls to be range() and items(), works in both Python 2 and 3, and is really what we want in 3 (which is what matters). But because it is so simple to do (and to find and remove once we completely switch to Python 3), make range() be an alias for xrange() in the two affected tests (044 and 163). In one instance, we only wanted the first instance of the result of a filter() call. Instead of using next(filter()) which would work only in Python 3, or list(filter())[0] which would work everywhere but is a bit weird, this instance is changed to use a generator expression with a next() wrapped around, which works both in 2.7 and 3.
