Thank you for so fast implementation!
Sorry for not answering on original e-mail. I've lost it somehow.
My comments so far:
What's the reason of insisting that path must be absolute?
May be it's just me, but I find it a bit scaring to use absolute path in .wks
The patch is relative to the rootfs directory from my point of view.
It also looks quite strange in the code to insist on absolute path
+ if not os.path.isabs(path):
+ msger.error("Must be absolute: --exclude-path=%s" %
and then immediately making it relative:
+
+ while os.path.isabs(path):
+ path = path[1:]
I know, this is just a matter of taste, but I'd not use brackets around
head, tail here. They're redundant and the code looks better without
them from my point of view.
+ (head, tail) = os.path.split(remaining)
This causes rmtree to throw NotADirectoryError on files:
+ for entry in os.listdir(full_path):
+ shutil.rmtree(os.path.join(full_path, entry))
