Bug Description

It looks like it should be correct given that its taking a hash of the key for the filename in the bucket dir, but it looks like its running afoul before it gets there.. sample script to reproduce (python+boto) against nova-objectstore (s3server.py)

import boto
import os
from boto.s3.connection import S3Connection, OrdinaryCallingFormat

s3 = S3Connection(
    aws_access_key_id=os.environ["EC2_ACCESS_KEY"],
    aws_secret_access_key=os.environ["EC2_SECRET_KEY"],
    host = os.environ["S3_URL"][len("http://"):],
    is_secure = False,
    calling_format=OrdinaryCallingFormat())

bucket = s3.create_bucket("es-testing-123")

print "new key"
key = bucket.new_key("abc.txt")
key.set_contents_from_string("abcdef")

print "new nested key"
key = bucket.new_key("zoo/abc.txt")
key.set_contents_from_string("abcdef")

fwiw the objectstore was never meant as a S3 replacement, so I wouldn't be surprised if other things failed.

Just to understand where the project is going, is there anything officially seen as an S3 replacement including API compatibility, Thierry?

Gustavo: No, I don't think that is a priority. Swift has an S3-ish wrapper for its own interface:

http://swift.openstack.org/misc.html#module-swift.common.middleware.swift3

In addition, Glance supports S3 backends.

But I don't think it is on the roadmap to have an S3 replacement that uses the S3 API.

Cheers,
jay

Wow, ok.. I clearly missed the AWS compatibility take there. Thanks Jay.

@Gustavo: afaict it was always about "EC2" compatibility (not "AWS"). Eucalyptus had the same approach, btw (by their own admission, Walrus was never meant to be deployed as a S3 competitor).

"""
Walrus is a storage service included with Eucalyptus that is interface compatible with Amazon's S3. Walrus allows users to store persistent data, organized as buckets and objects (see Amazon's S3 Getting Started Guide for more information). Walrus system options can be modified via the administrator web interface.
