Marios Andreou commented on DTACLOUD-306:
-----------------------------------------
Christian: thanks very much for your input! I was confused at first by your
explanation, because I know that the openstack rubygem we are using (and to
which deltacloud core developers are the main contributors) actually does
something like:
[in openstack-1.0.1/lib/compute/server.rb ]:
49 def populate(data=nil)$
50 path = "/servers/#{URI.encode(@id.to_s)}"$
51 if data.nil? then$
52 response = @compute.connection.req("GET", path)$
53 OpenStack::Exception.raise_exception(response) unless
response.code.match(/^20.$/)$
54 data = JSON.parse(response.body)["server"]$
55 end$
[...]
as you can see in line 50 above, the id passed from deltacloud is already
turned into a string. But you are right that the problem is in the 'to_i' from
the deltacloud driver... since for example the instance id
"2a308316-ee76-4df7-b050-c7de0d18b569" is converted to the integer 2 (the to_i
parses the string and extracts whatever leading numbers it can, and returns
just 0 if there are none). So the result was that the openstack rubygem was
making the call with an instance id of "2".
I'll remove the extraneous 'to_i' from the deltacloud driver and run the
openstack tests to make sure all is in order before sending the patch here.
I'm a little confused that Leander was able to get at specific images though if
the same applies to those.
Thanks again for your input, marios
