Running against a new server without a typemap/stream spec will cause errors on trying to set up either.

The 'p4 streams' and 'p4 typemap' specs don't get populated correctly by the fetch_* commands if they are empty.

Apologies for not just giving you PR, I don't have permission from employer; but you can use .get("TypeMap", []) etc instead of ["TypeMap"] and all is fine. Thanks for the tool, it looks very promising.

Thanks Brett!
I just submitted a PR #2 to fix the fetch_typemap issue and update the tests.
From testing it, I don't think fetch_stream has the same issue, because that command returns an empty streamspec if the stream doesn't already exist. Or, if the path is malformed or the depot doesn't exist, it will throw an exception, which I would imagine is the desired behavior.

Let me know if there's something I've missed and that fetch_stream can return an empty dict. Otherwise hopefully this gets merged and we can close the issue!

Thanks Jase,

For fetch streams, I conflated a very similar issue with iterate_streams(), which usually just runs 'p4 streams' and creates an iterator. In the case that 'p4 streams' is empty, you get an exception for the warning 'No such stream.'. Needs a try/except P4.P4Exception

existing_stream_names = {_["Stream"] for _ in server.iterate_streams()}
