Hi folks,
I was looking to unretire the unmaintained python-pp because some neuro
packages still use it but then was reminded by @music that we already
provide python-ppft which is a maintained fork and drop-in replacement
for pp.
https://github.com/uqfoundation/ppft
Currently python3-ppft provides these:
$ rpm -q --provides python3-ppft
python-ppft = 1.6.6.4-2.fc35
python3-ppft = 1.6.6.4-2.fc35
python3.10-ppft = 1.6.6.4-2.fc35
python3.10dist(ppft) = 1.6.6.4
python3dist(ppft) = 1.6.6.4
Can we also provide all these for `pp` so that packages in Fedora that
require pp automatically use ppft?
I tried adding `%py_provides pp` to python3-ppft, and while that does
add a few of these, it does not add the python3.10dist(pp) or
python3dist(pp) ones (which are autogenerated from the metadata?):
$ rpm -q --provides -p
./results_python-ppft/1.6.6.4/3.fc36/python3-ppft-1.6.6.4-3.fc36.noarch.rpm
python-pp = 1.6.6.4-3.fc36
python-ppft = 1.6.6.4-3.fc36
python3-pp = 1.6.6.4-3.fc36
python3-ppft = 1.6.6.4-3.fc36
python3.10-pp = 1.6.6.4-3.fc36
python3.10-ppft = 1.6.6.4-3.fc36
python3.10dist(ppft) = 1.6.6.4
python3dist(ppft) = 1.6.6.4
Would there be a way to include these machine readable provides too
since these forms are used by other packages in the automatically
generated requires etc. (if this is the right thing to do)?
I guess the alternative would be that every package that requires pp be
patched to require ppft, but tweaking a single python-ppft package would
be less work. :)
Hi,
These are generated from Python metadata, e.g. install_requires in
setuptools:
https://github.com/uqfoundation/ppft/blob/a4dd5832103512f6df717637b03fb507a00efd84/setup.py#L200
If you only add the RPM provides, tools that read the Python-specific
metadata might complain about not finding pp. And unfortunately Python
packaging doesn't have good support for "virtual provides"
(Provides-Dist) yet.
So it looks like it would be best to patch setup.py (or equivalent) in
all dependent packages. And perhaps push the change upstream, if ppft is
better than pp. (I don't know anything about these packages.)
