gobject-introspection: Switch to python 3

[tla@…]

At the moment, gobject-introspection requires Python 2 to build (via py27-mako). There is as far as I can tell no good reason for this - it works fine with py34-mako too. It would be good to have a port variant for python 3, and perhaps even better to make it the default.

I tried but the current stable version (1.44.0) doesn't build using python3. However, there have recently been some python3 commits upstream in the unstable branch and I am testing them now.

I agree it would be nice to upgrade to python3 so will leave this ticket open and make the necessary changes when possible. Thanks for the suggestion.

Hi,

It is now 3 year later, may be it could be interesting to consider again moving to python3 ?

Thanks,

An ​additional page confirms that it doesn't require Python2. It insist a reader to compile this library against Python3

[eirnym (Eir Nym)]

And it indeed compiles with Python3 on my local machine. I changed in port numbers and it worded.

Also configure code and some other internals mention Python3, even version 3.8 explicitly.

I also tried changing the python version to 3.7 locally and didn't run into any problems.

Considering that we are now at 10 month of Python2 End Of Life, switching to python3 should be taken seriously. Thanks.
