Hi,

Here's an update on where we're standing right now.  Including only non-
masked packages.  Please note that there's only month left.  Afterwards,
the offending packages will be cleaned up / last rited (except for
build-time deps).


Waiting for cleanup of old (non-trivial!):
- dev-db/percona-server
- media-tv/mythtv
- x11-plugins/enigmail

Build-time deps, only old versions:
- dev-lang/spidermonkey

Build-time deps, to stay for the time being:
- dev-python/pypy*
- dev-qt/qtwebengine
- games-strategy/0ad
- www-client/chromium

Waiting for py3 port (likely last rite candidates):
- games-engines/renpy

Dependencies of other packages on the list:
- dev-python/numpy-python2 (games-engines/renpy)
- dev-python/pygame_sdl2 (likewise)

RenPy 7.4.0, released on the 26th of November, features "new Python 3 
compatibility mode". It is of course up to the maintainer of this 
package to decide how to proceed but were this up to me, I would very 
much rather version-bump games-engines/renpy (in spite of 7.4.0 being 
described by upstream as a pre-release) than last-rite it altogether.

Sure but I'm afraid the games will need explicit porting to py3 as well.

Well, the games will probably have to go - if I see correctly we have 
currently got 4 games-engines/renpy revdeps in the tree 
(games-misc/katawa-shoujo, games-rpg/asphyxia, games-rpg/sakura-spirit, 
games-rpg/the-royal-trap) and they all explicitly depend on a slotted 
older version of the engine.

Looks like you misunderstood what "Python 3 compatibility mode"
means. See official explanation:
https://www.renpy.org/dev-doc/html/changelog.html#python-2-python-3-compatibility-mode
*****************************************************
Full Changelog
7.4.0
[...]
Python 2/Python 3 Compatibility Mode

While Ren'Py is not yet supported on Python 3, this release of
Ren'Py includes several features to allow you to begin writing
scripts that will work on both Python 2 and Python 3.
*****************************************************

Just to be sure I tried to build renpy-7.4.0 using python3: it
fails because it still uses python2 code inside (but with import
future, so it can support scripts in python 3).

Python3 support for the RenPy itself is expected in 8.0 version.

1. pygame_sdl2 is ported to python3, so there is no need to remove
it even if renpy will be temporarily gone.

2. It should be possible to keep renpy and games as masked in the
tree, but this will require users to setup some python2 env
themselves. If this is an acceptable option, I can bump renpy to
7.4.0 in the tree.

So I have. Oh well, last rites it most likely is then.  Or move py2 versions of RenPy and their revdeps to a dedicated overlay, maybe. I am not quite convinced simply having then masked in the main tree makes sense, as these will have to stay masked even after RenPy 8.0 has come out.

Do we have a dedicated py2 overlay? Renpy has quite some py2 deps,
so it will be reasonable to support it in such overlay instead of
duplicating job for common packages.

The sense I see:
1) it will make it easier to update to 8.0;
2) for users willing to use renpy it will be a starting point,
though they'll need to setup py2 outside of portage somehow, maybe
using pip.

But maybe it will be easier for users to use bundled renpy from
games (it often comes with its own py2); though not all games have
linux port — that is the killer feature of the in-tree renpy
version.
