Resolver.glob on node without children gives IndexError

[lverweijen]

Resolver.glob on node without children gives IndexError.
For non-existing paths it also seems to return nothing instead of an empty iterable, which would be preferred.
When using resolver.get instead it gives correct output instead.

import anytree
node = anytree.Node("root")
resolver = anytree.Resolver()
resolver.glob(node, "/root")  # IndexError, expected [node]
resolver.glob(node, ".")  # IndexError, expected [node]
resolver.glob(node, "")  # IndexError, expected [node]
resolver.glob(node, "..")  # IndexError, expected (ResolverError or just [], but should be consistent with get)
resolver.glob(node, "root")  # Returns nothing, expected []
resolver.glob(node, "bla")  # Returns nothing, expected []
resolver.glob(node, "/bla")  # Returns nothing, expected []

Version used is 2.8.0

By the way, can't glob just use the standard library function fnmatchcase in the background (which gives you some features for free)?

Seems to be the same as #125 (but that issue is closed)

I agree, that the Resolver is a little bit too addicted to exceptions.
I will add a relax attribute, which gives expected empty list.
I will also ensure consistency between get and glob.
