The %{? in the comment made the entire block of macros not work.
Since nobody actually used those on Fedora, because they did not exist,
we can safely remove them. No need to document this in the %changelog.

# That means that it owns the "python3" namespace:
|
|
# - python3 package name
|
|
# - /usr/bin/python3 command
|
|
# - python3-foo packages are meant for this version
|
|
# Other versions of Python 3 always contain the version in the namespace:
|
|
# - python3.XX package name
|
|
# - /usr/bin/python3.XX command
|

# - python3.XX-foo packages (if allowed)

# Python spec files use the version defined here to determine defaults for the
|
|
# %%py_provides and %%python_provide macros, as well as for the "pythonname" generator that
|
|
# provides python3-foo for python3.XX-foo and vice versa for the default "main" version.
|
|
# E.g. in Fedora 33, python3.9-foo will provide python3-foo,
|
|
# python3-foo will provide python3.9-foo.
|

|
|
# This always contains the major.minor version (with dots), default for %%python3_version.

# The pkgname version that determines the alternative provide name (e.g. python3.9-foo),

# This is left intentionally a separate macro, in case the naming convention ever changes.
