euca-describe-images yields no output when -a/-o/-x unspecified

[Garrett Holmstrom]

euca-describe-images rather unhelpfully gives no output when one doesn't specify -a, -o, or -x. This isn't necessarily a problem, but it would be nice to either search *something* by default or print a warning that says, "Hey, give me something to search!" This especially causes confusion when one specifies an image to look for but no options. ``euca-describe-images ami-bb709dd2'' yields no output, for example, even though the image clearly exists and is visible to the user.

ec2-describe-images defaults to listing all images owned by the user when given no arguments. It searches through all images visible to the user when an image ID is specified. This may or may not be a good default, but if the default is to remain searching an empty set, then a warning saying so would be beneficial.

Version-Release:
euca2ools-1.2-1.fc12 (Fedora 12)

Right now this package is an unmodified build of 1.2.

Description of problem:
euca-describe-images rather unhelpfully shows no output if none of -o -a -x are specified

Version-Release number of selected component (if applicable):
euca2ools.noarch 0:1.2-1.fc12

How reproducible:
Always

Steps to Reproduce:
1. euca-describe-images -A 01CA26RV706EVPYQMX02 -S ahtrfBT+nPZtzTyTCnYRXziCm5pVya3ZL9XFYAtR -U https://ec2.amazonaws.com
2.
3.

Actual results:
(Nothing)

Expected results:
Amazon's EC2 tools show those images which the user owns (-o self). I'm not saying this should be the default behavior, but something should sure be described, or an error message saying to the user "hey, pick something to describe, this won't output anything".

Even specifying "euca-describe-images ami-????????" shows nothing since it doesn't know the owner designation.

Agreed, a change in its behavior here would definitely make things clearer. I submitted this upstream; we'll see what they have to say. I can't patch such behavioral changes in, of course, so we'll see what, if anything, they do with the next release.

Hi Garrett,

can you please check if the latest head fixes your problem (no output when you list an image id)?

$ euca-describe-images ami-bb709dd2
IMAGE ami-bb709dd2 ubuntu-images-us/ubuntu-karmic-9.10-i386-server-20100121.manifest.xml 099720109477 available public i386 machine aki-5f15f636 ari-d5709dbc

[Garrett Holmstrom (gholms)]

The current head seems to fix the lack of output when an image ID is given.

What would you think of adding a warning that triggers "if defaults and len(image_ids) == 0" somewhere around line 124 so people running the program with no arguments whatsoever know not to expect any output? Or maybe specifying a default set of images to display in that case?

This was fixed in euca2ools-2.0, which displays all images by default.
