File representation for folders
===============================
Folders can be represented in file-system-like protocols (e.g. FTP). An
adapter abstracts some internals away and adds support for accessing the
'++etc++site' folder from those protocols.
>>> from zope.container.folder import Folder
>>> from zope.container.directory import ReadDirectory
>>> folder = Folder()
The new folder isn't a site manager and doesn't have any entries:
>>> fs_folder = ReadDirectory(folder)
>>> list(fs_folder.keys())
[]
>>> fs_folder.get('test', )
>>> fs_folder['test']
Traceback (most recent call last):
KeyError: 'test'
>>> list(fs_folder.__iter__())
[]
>>> fs_folder.values()
[]
>>> len(fs_folder)
0
>>> fs_folder.items()
[]
>>> 'test' in fs_folder
False
This is a short regression test for #728: we get a KeyError when trying to
access non-existing entries:
>>> from zope.security.proxy import ProxyFactory
>>> from zope.security.checker import NamesChecker
>>> proxied_folder = ProxyFactory(fs_folder, NamesChecker(('get',)))
>>> proxied_fs_folder = ReadDirectory(proxied_folder)
>>> print proxied_fs_folder['i dont exist']
Traceback (most recent call last):
KeyError: 'i dont exist'
