Set pushed.

The general_assembly.pl script should now be usable as the authoritative
source for GA members.

The patches mostly LGTM.

My Perl knowledge in general is really mostly from 20 years ago.
So if there is any Perl-ish devil in the details I surely have
overlooked it.

Please pardon me if I missed any details on how the program works.
The edge cases are always the tricky stuff...

One thing about this patch and that program in general is a bit
unfortunate: The use of PerlDate is_between.

Here is the doc I found for it:

    $dt->is_between( $lower, $upper )
    Checks whether $dt is strictly between two other DateTime objects.

    "Strictly" means that $dt must be greater than $lower and less than $upper. If it is equal to either object then this method returns false.


AFAIU it affects the script in 2 places:

1. In subroutine get_date_range:
   Here the exact day matching date_ga_rule is treated like
   anything >= date_first_regular

2. In the loop adding the extra member. The member would not be added
   on both, the day they were elected nor the day 2 years after.

Case 1 should be "strictly academical" and thus not really important
because to my knowledge no vote was started on that day.

For case 2 it will be not important on most days, but it would seem
more common and intuitive to use either the closed interval or a
half open interval. Where including the first and the last day or
including the first and excluding the day seem most natural to me.


Best regards,
  Alexander


P.S.
As date calculations always turn out nightmares if you look at them
long enough, it would possible be a good idea to always use UTC and
review how time zones are handled in git CLI.

P.P.S.
For quick reference follow copies for both places referenced above:

Case 1:
    sub get_date_range {
        my ($now) = @_;

        # date on which the GA update rule was established, and the voter list
        # was extraordinarily updated; cf.:
        # * http://lists.ffmpeg.org/pipermail/ffmpeg-devel/2023-October/316054.html

        # * http://lists.ffmpeg.org/pipermail/ffmpeg-devel/2023-November/316618.html
        #   Message-Id <5efcab06-8510-4226-bf18-68820c7c69ba@betaapp.fastmail.com>
        my $date_ga_rule       = DateTime->new(year => 2023, month => 11, day => 06);
        # date when the regular update rule is first applied
        my $date_first_regular = DateTime->new(year => 2024);

        if ($now->is_between($date_ga_rule, $date_first_regular)) {
            return ($date_ga_rule->clone()->set_year($date_ga_rule->year - 3), $date_ga_rule);
        }

        if ($now < $date_ga_rule) {
            print STDERR  "GA before $date_ga_rule is not well-defined, be very careful with the output\n";
        }

        my $cur_year_jan  = $now->clone()->truncate(to => "year");
        my $cur_year_jul  = $cur_year_jan->clone()->set_month(7);
        my $date_until    = $now > $cur_year_jul ? $cur_year_jul : $cur_year_jan;
        my $date_since    = $date_until->clone()->set_year($date_until->year - 3);

        return ($date_since, $date_until);
    }


Case 2:
    foreach my $entry (@extra_members) {
        my $elected = $entry->[2];
        if ($date->is_between($elected, $elected->clone()->set_year($elected->year + 2))) {
            $assembly{$entry->[0]} = $entry->[1];
        }
    }

I can only say wow as I know zero about perl. Is it the same reason to write it in perl as
automake so it can be run everywhere?

These objects are not days, they are specific times with nanosecond
resolution. Since I'm not specifying time in the constructor, it
defaults to the first nanosecond-long instant of the day, so none of
these problems really apply.

tools/general_assembly.pl
Can't locate object method "is_between" via package "DateTime" at tools/general_assembly.pl line 75.

is_between seems to have been added in 1.52   2020-02-29
So this is unavailable in several distros, it works with cpan though
but this shoould be docuemnted if it cannot be avoided

thx
