When looking up a container or pod by from user input, we handle collisions between names and IDs differently than Docker at present. In Docker, when there is a container with an ID starting with "c1" and a container named "c1", commands on "c1" will always act on the container named "c1". For the same scenario in podman, we throw an error about name collision. Change Podman to follow Docker, by returning the named container or pod instead of erroring. This should also have a positive effect on performance in the lookup-by-full-name case, which no longer needs to fully traverse the list of all pods or containers.

Nice. Specific should always take priority on guess or less specific (like short-hand id prefix matching with collisions possibility) |
