[Bug 719547] [NEW] euca2ools doesn't parse EC2_URL correctly

[Andreas Hasenack]

Public bug reported:

Binary package hint: euca2ools

The EC2_URL shell variable holds an URL to an EC2 or Eucalyptus
endpoint.

There is a problem with the URL parsing code where, if said URL doesn't
contain a port number, it thinks the whole URL is a hostname.

Example (with fake keys on purpose):

export EC2_URL="https://staging.landscape.canonical.com/cloud/ec2/landscape-devel/amra-uec/dev1"
export EC2_SECRET_KEY=1
export EC2_ACCESS_KEY=1

$ euca-describe-regions 
(wait a long time).
[Errno -2] Name or service not known

Now change the EC2_URL so that is also includes the port number:
export EC2_URL="https://staging.landscape.canonical.com:443/cloud/ec2/landscape-devel/amra-uec/dev1"

And the expected answer comes right away:
$ euca-describe-regions 
AuthFailure: No user with access key '1'

A packet sniffer shows that without the port number in the URL, euca2ools is trying to resolve the wrong hostname:
  0.000000     10.0.1.7 -> 10.0.1.1     DNS Standard query AAAA staging.landscape.canonical.com/cloud/ec2/landscape-devel/amra-uec/dev1
  0.009434     10.0.1.1 -> 10.0.1.7     DNS Standard query response, No such name
  0.028092     10.0.1.7 -> 10.0.1.1     DNS Standard query A staging.landscape.canonical.com/cloud/ec2/landscape-devel/amra-uec/dev1
  0.048702     10.0.1.1 -> 10.0.1.7     DNS Standard query response, No such name

I tried with both euca2ools 1.2-0ubuntu10.1 from lucid and
1.3.1-0ubuntu5 from natty.
