Hi Roland,


I've committed the patches from #13567 and last nights master builds
have completed OK. Even Focal, which has been failing since python2
support was removed in Focal a week or two ago, build OK :). Thanks Roland!


As for the script Bill is probably the one to ask about that. My
personal opinion is we should be encouraging users to switch to using
the python3 bindings, the latest  version of most/all? distros are going
to remove support for python2 so they wont have much choice soon. Maybe
add your script to the wiki but make it clear it's only a short term
solution that wont work in the near future?


Paul H.

Hi Roland,

My initial attempt was to modify the Makefile for the Python bindings and have it detect
if v3 and v2 were available. Then run setup.py for discovered Python versions. I wasn't
successful.

So, I added this some time ago: https://www.mythtv.org/wiki/Python3_Conversion#Install_both_sets_of_bindings
and it's linked to from the release notes. It only works for those building from source
though.

Roland, sounds like your script works for those not building from source. I think it
could live in the Python3_Conversion Wiki. If you don't have access to the Wiki
yet, email me a copy and I'll add it.

For most of the time during the conversion, I ran with both v3 and v2 installed.

As to my _deprecated_ comment in the release notes: I think it's still true. But
packagers make the decision. That way if there's a distro that doesn't support
v3, they can still choose v2.

I posted a "Heads up" in the -users list and on the Forum.

https://lists.gt.net/mythtv/users/628768
https://forum.mythtv.org/viewtopic.php?f=30&t=3384

I got one and two responses respectively. Could mean it's not going to be an
issue, OR that folks are planning to work things out when the move to v31.

My concern was for folks with private or Wiki tools that need conversion (and may
simply stop working on v31.)

Just a heads up, current mythtv-frontend from ppa:mythbuntu/31 will not
install on Ubuntu 18.04 LTS as python3-imdbpy is not available.

I don't see any users of imdbpy in the source. Commit b5de3b264d6a2384caa9957de505d3e08f3af2ab
removed it in 2011. Looks like it was never removed from packaging. I'll take the ticket.
