Hi All,
the current python test packages remove the link python->python2.7
and replace with an alternative appraouch.
Before making the switch, I would like to review the packages that could
be broken, so I looked at all packages, not in "python*-*" form,
that pull one of the "python", "python2" and "python27" using
$ cygcheck-dep -O -S -q -n python..
as base.
There are almost 200 binary packages
(of the almost 9000 currently present on 64 bit)
The list with source package and maintainer is here:
https://drive.google.com/file/d/1xaPzIZ78JzHtJXcdzB77qJoeNlvVQRJq/view?usp=sharing
I know that Mercurial need rebuild, and I assume the same
for subversion (that I plan to adopt).
Could you please check your packages if they will work with
preferred python3.8 ?
Texlive and fontforge seem the most urgent, IMHO, for a verification.
As python2 is officially dead, a fast switch is nice to have
without braking too many critical packages.
Thanks in advance & Regards
Marco

And how can I ensure that units_cur is tested using only python38 modules?
Will the hash-bang override the command line run python38 `which units_cur`?

Hi Brian,
python3-requests for the time being will pull python36-requests.
That is fine for your
#!/usr/bin/python3.6m
Cygport has hard coded the OBSOLETES, this is something
we need to change in cygport:
>>> python36-requests OBSOLETES: python3-requests
> And how can I ensure that units_cur is tested using only python38 modules?

rebuilding from your source I had
units requires: cygwin findutils libreadline7 python38 python38-requests
It seems the "inherit python3" is pulling the current choice
of my system
$ alternatives --display python3
python3 - status is auto.
link currently points to /usr/bin/python3.8
/usr/bin/python3.7 - priority 37
/usr/bin/python3.6 - priority 36
/usr/bin/python3.8 - priority 38
Current `best' version is /usr/bin/python3.8.
Regards
Marco

I think TeX Live should be fine. All of the python scripts provided by the
texlive-collection-* packages are identical across platforms, so any python3
incompatibilities would almost certainly have been reported and fixed by now. I
think all I have to do is rebuild the collections that contain python scripts to
make sure I pick up the latest versions of the upstream packages, and also to
let cygport update the dependencies. I can do that quickly as soon as cygport
is ready for the new system.
My other package listed in your spreadsheet, bzr-fastimport, is of very low
priority. It can be dealt with when and if bzr is updated. Since there hasn't
been an upstream bzr release in 5 years, updating bzr might simply be a matter
of changing the shebang in /usr/bin/bzr to specify python2. But that's up to Jari.

Same on mine as of package release time.
I still have direct symlinks from installs:
$ llrt -go /bin/python{,[23]*}
-rwxr-xr-x 1 9.1K Apr 10 2020 /bin/python3.7m.exe*
lrwxrwxrwx 1 14 Apr 11 2020 /bin/python3.7 -> python3.7m.exe*
-rwxr-xr-x 1 9.1K May 23 2020 /bin/python2.7.exe*

-rwxr-xr-x 1 9.6K Jun 8 2020 /bin/python3.6m.exe*
lrwxrwxrwx 1 14 Jun 26 2020 /bin/python3.6 -> python3.6m.exe*
lrwxrwxrwx 1 13 Jun 26 2020 /bin/python -> python2.7.exe*

lrwxrwxrwx 1 16 Jan 2 13:39 /bin/python3-config -> python3.8-config*
Problem is if units goes quiet for a while, as it has sometimes for 2-3 years,
averaging a release a year, it may require python3.X packages to stay around
long after really required, even if obsoleted by many later releases, when it
really just needs to depend on python3{,-requests}.
At the moment, python 3.6 has to stay around until the next units release!
I would rather not have to generate package releases per python release (or few)
just for this, but I don't mind testing each.
Should I hack the build files next release to avoid resolving the symlinks and
retain the base version?

I've promoted fontforge packages from test to current, which pass ctests.

I've started doing some trial rebuilds on a system with the test python3
packages installed. I'm finding that cygport doesn't pick up any python
dependency for some packages (such as texlive-collection-binextra-doc) even
though there's a script with a shebang "#!/usr/bin/env python". Marco, you've
probably said this already, but could you confirm that this is to be expected
until cygport is modified?

Hi Ken,
it is expected as python is not anymore reporting to any package.
Just add python38 or python3 as dependency.
I plan to put python38 that obsoletes python3
