Add ability to parse all files within a directory. Additionally add the ability to parse all results in the KUnit debugfs repository.
Nice, I'd been hoping for this. It's enough to pull me back in for a bit :)

Hi Daniel!
Yes, happy to make this change for the next version.
total_test = kunit_parser.Test()
total_test.status = kunit_parser.TestStatus.SUCCESS

This branch no longer does anything, since we only parse what's in `parsed_files`
E.g. if you try $ kunit.py parse $FILENAME it'll work whereas $ kunit.py parse < $FILENAME will do nothing
We'll need to rework the control flow somehow
Ahh I see. Thanks for bringing this to my attention! I will change this for the next version.
else:
with open(cli_args.file, 'r', errors='backslashreplace') as f:
elif cli_args.file_path == "debugfs":
for (root, _, files) in os.walk("/sys/kernel/debug/kunit"):
for file in files:
if file == "results":
parsed_files.append(os.path.join(root, file))
elif os.path.isdir(cli_args.file_path):
for (root, _, files) in os.walk(cli_args.file_path):
for file in files:
parsed_files.append(os.path.join(root, file))
just a note here, we could make this a bit terser via parsed_files.extend(os.path.join(root, f) for f in files)
and the debugfs branch could be rendered as parsed_files.extend(os.path.join(root, f) for f in files if f == "results")
Will do.
elif os.path.isfile(cli_args.file_path):
parsed_files.append(cli_args.file_path)
nit: should there be an `else` here that prints a warning?
Example that would trigger this case and silently do nothing $ mkfifo /tmp/example_fifo $ ./tools/testing/kunit/kunit.py parse /tmp/example_fifo
<no output>
Yep you are definitely right I will add one here.

Should this mention that the make `debugfs` string works?
type=str, nargs='?', metavar='input_file')
Tangent: would it be useful to allow the user to pass in multiple files now and set this to nargs='*'?
E.g. $ kunit.py parse /my/dir/some_prefix*
It would also let people implement their own version of the debugfs logic via $ find /other/debugfs/dir -name 'results' | xargs kunit.py parse
That could be useful if the user has recursively copied off the debugfs from a test machine and wants to inspect it elsewhere, for example.
Oh this is an interesting idea. I will play around with it!
Thanks for looking this patch over! -Rae
Thanks, Daniel
