listing of keys is inconsistent with boto's implementation

[antimora]

The following code demonstrates that the listing of keys is inconsistent with boto's implementation.

Here is the output:

real s3
[u'toplevel/x/key', u'toplevel/x/y/key', u'toplevel/x/y/z/key', u'toplevel/y.key1', u'toplevel/y.key2', u'toplevel/y.key3']
[u'toplevel/y.key1', u'toplevel/y.key2', u'toplevel/y.key3', u'toplevel/x/']

mocked s3
[u'toplevel/y.key1', u'toplevel/y.key2', u'toplevel/y.key3', u'toplevel/x']
[u'toplevel/y.key1', u'toplevel/y.key2', u'toplevel/y.key3', u'toplevel/x']

The test code:

import boto
from boto.s3.key import Key
from moto import mock_s3

BUCKET = 'dilshodtest1bucket'
prefix = 'toplevel/'

def main():

    conn = boto.connect_s3()
    conn.create_bucket(BUCKET)
    bucket = conn.get_bucket(BUCKET)

    def store(name):
        k = Key(bucket, prefix + name)
        k.set_contents_from_string('somedata')

    names = ['x/key', 'y.key1', 'y.key2', 'y.key3', 'x/y/key', 'x/y/z/key']

    for name in names:
        store(name)

    delimiter = None

    keys = [x.name for x in bucket.list(prefix, delimiter)]

    print keys

    delimiter = '/'
    keys = [x.name for x in bucket.list(prefix, delimiter)]

    print keys


if __name__ == '__main__':

    print 'real s3'

    main()

    print 'mocked s3'

    mock = mock_s3()
    mock.start()
    main()
    mock.stop()
