Instead of checking iotests.py only, check all Python files in the qemu-iotests/ directory. Of course, most of them do not pass, so there is an extensive skip list for now. (The only files that do pass are 209, 254, 283, and iotests.py.) (Alternatively, we could have the opposite, i.e. an explicit list of files that we do want to check, but I think it is better to check files by default.) Unless started in debug mode (./check -d), the output has no information on which files are tested, so we will not have a problem e.g. with backports, where some files may be missing when compared to upstream. Besides the technical rewrite, some more things are changed: - For the pylint invocation, PYTHONPATH is adjusted. This mirrors setting MYPYPATH for mypy. - Also, MYPYPATH is now derived from PYTHONPATH, so that we include paths set by the environment. Maybe at some point we want to let the check script add '../../python/' to PYTHONPATH so that iotests.py does not need to do that. - Passing --notes=FIXME,XXX to pylint suppresses warnings for TODO comments. TODO is fine, we do not need 297 to complain about such comments. - The "Success" line from mypy's output is suppressed, because (A) it does not add useful information, and (B) it would leak information about the files having been tested to the reference output, which we decidedly do not want.
