# There are multiple Python 3 versions packaged, but only one can be the "main" version |
|
# 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. |
|
# |
|
# There are two macros: |
|
# |
|
# 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), |
|
# set to the same as above, but historically hasn't included the dot. |
|
# This is left intentionally a separate macro, in case the naming convention ever changes. |

# python3_pkgversion specifies the version of Python 3 in the distro. |

# Alternatively, it can be overridden in spec (e.g. to "3.8") when building for alternate Python stacks. |

# locations. We want each Python stack in RHEL to have their own wheels, |
|
# because the main python3 wheels (which we can't upgrade) will likely be |
|
# quite old by the time we're adding new alternate Python stacks. |

# - In ELN we want to follow Fedora, because builds for ELN and Fedora rawhide |
