[v3] location-importer.in: track original countries as well
Commit Message
This helps us to determine how many network objects have more than one
country set, and what their original country code set looked like.
The third version of this patch uses ALTER TABLE to add the column for
original countries, preventing existing SQL setups from breaking, and is
correctly based against the current "master" branch.

It would be more Pythonic to write “if not key in inetnum:”.
I believe your implementation creates a list which has to be searched whereas mine performs a dictionary lookup which should be much faster. It wouldn’t matter much when you only have a hand full of elements to check, but since we perform this code tens of thousands of times, every little bit counts.

You call .upper() a second time when you could just store the value and use that instead.

Would you submit a second patch that fixes those minor things and I will merge both?

Hello Michael,
thanks for your reply and the annotations.
Patch #4390 (https://patchwork.ipfire.org/patch/4390/) should fix them. :-)
Thanks, and best regards,
Peter Müller
