Subject svn commit: r1095168 - /incubator/deltacloud/trunk/server/lib/deltacloud/drivers/ec2/ec2_driver.rb
Date Tue, 19 Apr 2011 18:56:56 GMT
Author: lutter

New Revision: 1095168

URL: http://svn.apache.org/viewvc?rev=1095168&view=rev
Log:
EC2: do not allow using env vars EC2_URL and S3_URL

Setting these variables to the empty string caused the aws gem to issue
invalid signatures on requests.

This issue was introduced in commit b8e725c6
