There shouldn't be that much to do. Enabling the python 3 binding building in the SDK is one thing, selecting the python 3 binding in the build system the other. Everthing else should start to work by itself then, except testing if the Python scripts were updated properly.

Both related to updating the packaging scripts.

Some distributives excluded FreeOrion from their repositories, need to fix that. I am not familiar with that world.
Aside from poking the packagers there is not much to do. Also what is a "distributive"?

Python-C++ glue is common for AI, universe generator, and turn events.

Linux is done.

SDK is ready but isn't released yet.

  • Remove compatibility from the python code
    I don't know if we want to do it in the release or later.
I think we should only disable tests for 2.7.

I hope they will take FreeOrion back after migration.

Do we plan to release any other features?
No. If something gets done alongside the migration to Python3 and is finished and ready in time so it can be included, it will, but I do not want to block the release for any other features than the Python3 stuff.
Linux, mac builds.
Do we need to do something here or it will work from the box?
As far as I can tell, there is nothing special to be done for the Linux platform (there is no Linux distro which doesn't support Python3 at this point to my knowledge). On macOS however we need to ship the Python3 framework instead of Python2, which means the app generation procedure needs to get updated accordingly.

What about SDK release? It doesn't left many big python3 errors to fix.

There are no more pylint warnings about python3 compatibility.
It does not mean that code compatible, o01eg has encountered a lot of errors that was not reported by this tool.

GitHub has some project management features. I will try to play with it. Forum is not best place to figure out what need to be done.

I think the next step will be to finish with these PRs:

I suppose the most important step is to release SDK.

Has the master branch of the SDK already received all the patches required for the switch to Python3?

And would a new SDK release also still support Python2?

Yes, I've built freeorion with python3 from master SDK.

Yes, SDK builds both python and boost-python libraries.

I have created a project on github.

Main purpose to track all things to be done in one place.

If you know that something to be done please create a card and add it tot he project.

If you have already done something just create a card and move it to done. Like new SDK with python3 support (is it cross platform?).
