Concept ACK modulo #26226 (comment)
It would be useful to include a build system release note when dependencies like this are updated, rather than leaving it hidden among the change-log sea; but that's aside this pr.

EOL of python shouldn't affect us, as we only use it to run the tests. Though, operating systems that ship with it going EOL would affect us. |

I don't get the argument to do this now when nothing has changed since #24017... |
|
No strong opinions. Paging @luke-jr. |
Right, there is no rush, so I guess I better close this. It just has to be done at some point in the future and I thought having a working patch couldn't hurt. |
Thanks. I did take a look at this the other day. My notes are that 3.6 was for RHEL, but it appears RHEL has since moved on. Personally, 3.6 is slightly more convenient to me since I have no easy way to get 3.7 anymore for testing (nor 3.6, but it's already installed) - Gentoo's oldest is 3.8. But I can adapt if need be. |

I think encoding is now unnecessary to specify in this line (and many others below) because text ensures stdout is a string and strings in Python 3 are by default unicode.

Heh, no. This only changed in Python 3.7, see https://docs.python.org/3/library/os.html#utf8-mode
I guess text/universal_newlines is not needed when specifying encoding, so might as well remove them completely.

Why wouldn't they be needed? Windows still has non-standard newlines.

Closing for now until there is a more pressing reason |

I hereby volunteer to provide the code necessary to generate a container sufficient to run the functional tests for anyone both (i) yelling and (ii) running an ancient version of Python. :) |

Right, Ubuntu Bionic will be EOL before the next release anyway. Centos Stream 8 runs until May 31st, 2024 , but they can install |

(Force pushed minimum to 3.7.16 and "maximum" to 3.12) |

The ci/lint system is separate from the ci/test system, so you should be able to get a test failure by reverting the image or packages in ci/test |

This reverts commit be59bd1 because the changes are no longer needed.

No, we also need git2.34 or later, which is only shipped in Ubuntu Jammy |

While there is nothing that requires a bump, it may require less maintenance to drop python3.6 support. Python3.7 is available through the package manager on all currently supported operating systems.
