Was adding tests while you were typing - is that one enough, or should I expand? |
|
If you have a case that I don't handle, then add it. But if this is enough, then just take them. |

We attempted to share all logic for parsing labels and environment variables, which on the surface makes lots of sense (both are formatted key=value so parsing logic should be identical) but has begun to fall apart now that we have added additional logic to environment variable handling. Environment variables that are unset, for example, are looked up against environment variables set for the process. We don't want this for labels, so we have to split parsing logic.
