Remove generate_protobuf_stubs.sh

[ftomassetti]

We have already another file to generate protobuf stubs inside the worldengine directory

[tcld]

Do any of those work properly? I have never managed to generate protobuf/World_pb2.py successfully, so I wasn't able to add variables to class World.

[ftomassetti]

for me the script inside the worldengine directory works

[tcld]

This one?
So I have to manually edit World.proto and it'll work? I don't see how it would generate World_pb2.py.

[ftomassetti]

yes, that one. You can try deleting the existing World_pb2.py and it should regenerate it.

[tcld]

Ok, a new file is indeed created. But it is using the method unicode() which for me (Python 3) causes NameError: name 'unicode' is not defined.

I already asked here #188 about how to regenerate a proper, working World_pb2.py. I still don't know how the current one was generated - maybe it can only be created under Python 2? Maybe it was manually edited afterwards?

protobuf3 should create the new file for us, on python2 or 3 and should work on both. Unless there has been a regression somewhere?

[tcld]

I remember when you generated the current file - I got the same broken result back then as I do now. So I don't think it is a regression; I think that either you are generating it differently than me or the problem is related to Python 3.

[ftomassetti]

protoc --version tells you 3.0.0a3, right?

[tcld]

No, it doesn't. I didn't know that was independent of the Python-installed protobuf. I'll try to update that and try again!

EDIT: That is probably the correct fix, even though I'll have to figure out how to update protoc on my system. Thanks for the hint!

[tcld]

I compiled a new version of Protobuf and everything works now - thanks for the hint, @ftomassetti .
The updating_protobuf_format.sh-script works fine, too. The output slightly changed but so far that doesn't seem to be a problem.

I had to add syntax = "proto2"; as the very first line of World.proto, however. (I assume "proto3" would be fine, too, but I didn't try).

So yes, it seems that generate_protobuf_stubs.sh should be removed - and World.proto slightly updated to keep things in working order. I'll have to do this for PR #188, so if you aren't in a hurry and see a chance of that PR being merged, you could just wait a little bit.

[ftomassetti]

No hurry, thanks for looking into this!

[tcld]

I think this can be closed. The file has been removed in #189 .

[psi29a]

roger that.
