Hey folks -

I noticed an wacky problem with that only manifests itself when I run a program from the top level of my home directory. (OS X Lion, Python 2.7, pyglet 1.1.4.):

import os

import pyglet

print __file__

dirname = os.path.dirname(__file__)

loc = pyglet.resource.FileLocation(dirname)

This program runs fine when it is located anywhere in my directory tree except precisely in my "root" home directory. When the file is there and I run it, the program hangs. When I stop it with a ctrl-c, I get the below error. Any idea what's going on?

Thanks...

No idea, sorry.  But that script (if you put it in a file) works fine on Mountain Lion (10.8.3) and the 1.2dev version from the repository.

I've discovered the problem, actually -- pyglet.resource.FileLocation seems to take an enormously long time when run from directories with a lot of subdirectories/files (such as my home directory). Can anyone clarify what's going on there? Should this be considered a bug?

I don't think that's the problem.  Take a look at the code for FileLocation (it's almost...no code at all)

class Location(object):

    def open(self, filename, mode='rb'):

        raise NotImplementedError('abstract')

class FileLocation(Location):

    def __init__(self, path):

        self.path = path

    def open(self, filename, mode='rb'):

        return open(os.path.join(self.path, filename), mode)

Hi Nathan -

I see your point, and yet the problem occurs. This works fine:

whereas this doesn't (the errors appear after I hit ctrl-c when I get
tired of waiting):
