Resolver.glob returns IndexError where Resolver.get does not

[zegervdv]

Example:

from anytree import Node
top = Node("top", parent=None)
sub0 = Node("sub0", parent=top)
sub0sub0 = Node("sub0sub0", parent=sub0)
sub0sub1 = Node("sub0sub1", parent=sub0)
sub1 = Node("sub1", parent=top)

from anytree import Resolver
r = Resolver('name')

Getting the top node from sub0:

>>> r.get(sub0, '..')
Node('/top')

Using glob:

>>> r.glob(sub0, '..')
.../anytree/resolver.py in __glob(self, node, parts)
    165     def __glob(self, node, parts):
    166         nodes = []
--> 167         name = parts[0]
    168         remainder = parts[1:]
    169         # handle relative

IndexError: list index out of range

Good catch. This is a bug. I will fix it. Will be fixed in 1.8.1

Great! Just tested with the fix and it works.

This issue seems to be back in 2.8.0 for the original relative case and when directly referencing the top node.

from anytree import Node, Resolver
top = Node("top", parent=None)
sub0 = Node("sub0", parent=top)
r = Resolver('name')

For sub0

>>> print(r.get(sub0, '..'))
Node('/top')
>>> print(r.glob(sub0, '..'))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Program Files\Python37\lib\site-packages\anytree\resolver.py", line 147, in glob
    return self.__glob(node, parts)
  File "C:\Program Files\Python37\lib\site-packages\anytree\resolver.py", line 171, in __glob
    nodes += self.__glob(node.parent, remainder)
  File "C:\Program Files\Python37\lib\site-packages\anytree\resolver.py", line 167, in __glob
    name = parts[0]
IndexError: list index out of range

Referencing the top level in the glob.

>>> print(r.get(top, '/top'))
Node('/top')
>>> print(r.glob(top, '/top'))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Program Files\Python37\lib\site-packages\anytree\resolver.py", line 147, in glob
    return self.__glob(node, parts)
  File "C:\Program Files\Python37\lib\site-packages\anytree\resolver.py", line 167, in __glob
    name = parts[0]
IndexError: list index out of range

It hasn't been released yet. The 1.8.1 above was a typo.

Will release 3.0.0 soon

Hey guys, I'm curious if this bug was ever patched. The repo still says it's on version 2.8.0
