I just know that when starting from __file__, it seems to work in that manner. I used that trick when I added the PYTHONPATH stuff directly into testenv a while back and never thought more of it. If it makes people uneasy to look at, I can just use .parent for the Principle of Least Surprise.

I don't see any potential problem with the second hunk because we're dealing with the path of a directory there, but "regular_file.py/.." looks a bit fishy to me and doesn't work if you ask the kernel. Is this guaranteed to work in Python or is it an implementation detail of Path that may change? Kevin

[PATCH] iotests: fix source directory location
If you invoke the check script from outside of the tests/qemu-iotests directory, the directories initialized as source_iotests and build_iotests will be incorrect. We can use the location of the source file itself to be more accurate.
