$ pkgcheck scan --net --commits --exit error
pkgcheck scan: error: failed running git log: fatal: unrecognized argument: --no-find-copies


No clue if it was removed, or if no such option ever existed.

    profiles: unmask =dev-vcs/git-2.43.2
    
    pkgcheck now has a workaround in stable and it's not a build-time failure
    so we can unmask this safely w/o worrying about upgrade ordering or anything.

Comment 5 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2024-02-17 00:11:14 UTC
I've posted a real fix at https://github.com/pkgcore/pkgcheck/pull/664.

The gist is that there is a real option but we were using a short form, and I assumed they were two *distinct* options, but instead git started rejecting ambiguous unknown options in some contexts.
Comment 6 Robin Johnson archtester Gentoo Infrastructure gentoo-dev Security 2024-02-17 06:29:37 UTC
yes, git changed it's behavior, but it wasn't a documented option as far as I can see.

Besides merging Sam's patch, I suggest asking Git upstream to add docs & testcase for --no-find-copies-harder

    git: fix no-copies option
    
    This reverts commit 9103513e26f9f2aeade5b563a49697c0e2665e3e.
    
    I originally added --no-find-copies in e688357bdc5773009bb2e106075d9852f2513f89
    to suppress git being too clever which ends up confusing our git integration, as
    we're not really interested in copies. I was going to use --no-find-copies-harder
    but I figured --no-find-copies sounded better as it was less specific and for
    our purposes here, we don't want copies at all, so why not?
    
    But --no-find-copies isn't a boolean option, it's just that until git commit
    5825268db1058516d05be03d6a8d8d55eea5a943 ('parse-options: fully disable option abbreviation with PARSE_OPT_KEEP_UNKNOWN'),
    it tolerated it and expanded it to --no-find-copies-harder. Oops!
    
    Let's use --no-find-copies-harder as we originally should have, as the only
    available option to control the behavior, modulo setting a similarity % threshold
    with --find-copies=n.
    
    We're fine to do this as, quoting the git-log docs:
    "[...] and options applicable to the git-diff[1] command to control how the changes each commit introduces are shown."
