Double asterisk wildcard overreach?

[xiaohan-xue]

hello! thanks for making this super useful library :)

In path_to_regex(), is it intended that the expanded ** regex match not only subfolders, but also partial filenames?

For example, a/**/b/ converts to re.compile('\\Aa/.*b/'), which will match paths like a/prefix_b/:

# expected ** behavior
>>> re.compile('\\Aa/.*b/').findall("a/b/")
['a/b/']
>>> re.compile('\\Aa/.*b/').findall("a/subfolder/b/")
['a/subfolder/b/']

# is this behavior also expected?
>>> re.compile('\\Aa/.*b/').findall("a/prefix_b/")
['a/prefix_b/']

This seems different from what git does; the docs say that codeowners follows mostly the same patterns as gitignore, which doesn't seem to recognize ** as prefixes:

# gitignore rule: a/**/b

# folder directory
>> ls -R a
a:
b  prefix_b

# matches rule, is ignored
>> git check-ignore a/b -n -v
.gitignore:8:a/**/b	a/b

# no matches
>> git check-ignore a/prefix_b -n -v
::	a/prefix_b

Thank you so much! Happy Halloween ^ ^
