annoyingly, they don't link to the actual bug in question, just say: > Systems with the rust-coreutils package version 0.2.2-0ubuntu2 or earlier have the bug, it is fixed in 0.2.2-0ubuntu2.1 or later. based on the changelog [0] it seems to be: > date: use reference file (LP: #2127970) from there: [1] > This is fixed upstream in 88a7fa7adfa048dabdffc99451d7aba1d9e6a9b6 which in turn leads to [2, 3] > Display the date and time of the last modification of file, instead of the current date and time. this is not the type of bug I was expecting, I assumed it would be something related to a subtle timezone edge case or whatever. instead, `date -r` is supposed to print the modtime of a given file: > date --utc -Is -r ~/.ssh/id_ed25519.pub 2025-04-29T19:25:01+00:00 > date --utc -Is 2025-10-23T21:46:47+00:00 and it seems like the Rust version just...silently ignored that expected behavior? maybe I'm missing something? if not this seems really sloppy and not at all what I'd expect from a project aiming to replace coreutils with "safer" versions. 0: https://launchpad.net/ubuntu/questing/+source/rust-coreutils/+changelog https://launchpad.net/ubuntu/questing/+source/rust-coreutils... 1: https://bugs.launchpad.net/ubuntu/+source/rust-coreutils/+bug/2127970 https://bugs.launchpad.net/ubuntu/+source/rust-coreutils/+bu... 2: https://github.com/uutils/coreutils/issues/8621 https://github.com/uutils/coreutils/issues/8621 3: https://github.com/uutils/coreutils/pull/8630 https://github.com/uutils/coreutils/pull/8630

It's supposed to pass the coreutils upstream tests. If it does, then that would mean the upstream tests still need work

  It... doesn't though: https://uutils.github.io/coreutils/docs/test_coverage.html https://uutils.github.io/coreutils/docs/test_coverage.html Neither this issue, which doesn't appear to be a bug at all but merely an unimplemented feature, nor the fact that uutils doesn't (yet) pass the entire testsuite, seem to me to at all be an indictment of the uutils project, merely a sign that it is incomplete. Which is hardly surprising when I get the impression it's primarily been a hobby project for a bunch of different developers. It does make me wonder about the wisdom of Ubuntu moving to it.

    Wow. Maybe I'm missing something but it seems really weird to replace a tool with a rewrite that doesn't pass the test suite!

      The non-passing test was only added like 17 hours ago: https://github.com/coreutils/coreutils/commit/14d24f7a530f587099057fa5411ebcf3cfc55e7d https://github.com/coreutils/coreutils/commit/14d24f7a530f58... So this is a good thing even for coreutils itself, they will slowly find all of these untested bits and specify behaviour more clearly and add tests (hopefully).

    I mean, how long did they take to realize that the more(1) they shipped had no equivalent in GNU coreutils at all? Its from util-linux: https://github.com/uutils/coreutils/issues/8975 https://github.com/uutils/coreutils/issues/8975 Doesn't look like people who do their homework
  - e2le 1y ago
    If it's not passing the test suite, then why is it even considered for inclusion in a distribution like Ubuntu? Ubuntu is likely used by 10s of millions of servers and desktops. I'm not sure why this kind of breakage is considered acceptable. Very confusing.

      Maybe the thought is that there will be more pressure now on getting all the tests to pass given the larger install base? It isn't a great way to push out software, but it's certainly a way to provide motivation. I'm personally more interested in whether the ultimate decision will be to leave these as the default coreutils implementation in the next Ubuntu LTS release version (26.04) or if they will switch back (and for what reason).

      It's a part of Ubuntu 25.10 to get it ready for prime time for Ubuntu 26.04. Users who need stability should use the LTS releases. The interim releases have always been more experimental, and have always been where Canonical introduces the big changes to ensure everything's mature by the time the LTS comes around.

  yeah, based on some more digging, it looks like a test case for `date --reference` in GNU coreutils was only added a few hours ago [0] so I assume it was in response to this bug. but I don't think that should let the uutils authors off the hook - if `--reference` wasn't implemented, that should have been an error rather than silently doing the wrong thing. after even more Git spelunking, it looks like that problem goes all the way back to the initial "Partial implemantion of date" [1] commit from 2017 - it included support for `--reference` in the argument parsing, including the correct help text, but didn't do anything with it, not even a "TODO: Handle this option" comment like `--set` has. 0: https://github.com/coreutils/coreutils/commit/14d24f7a530f587099057fa5411ebcf3cfc55e7d https://github.com/coreutils/coreutils/commit/14d24f7a530f58... 1: https://github.com/uutils/coreutils/commit/41d1dfaf440eabba3001595d15aaa150eb19d207#diff-4e9c0c311083a12291320e66258a163afba04e4af79e4a57dc56fe7d73338295R211-R212 https://github.com/uutils/coreutils/commit/41d1dfaf440eabba3...

  > then that would mean the upstream tests still need work More coverage is nice, but the foremost care should be to do the right thing, not have some tests for it. Some cultures do not include testing-first and instead treat tests as a tool for edge cases. Nobody bothered to add a tests, for -r, because the did not thing of that as an edge case, but as a core behaviour.
