Yeah, I remember when we used to use them, but then removed them due
them changing so much.
Ahh. That does sound pretty well thought out then. Yeah, let’s up it to
5.14, as we definitely require it for
Koha/SearchEngine/Elasticsearch/QueryBuilder.pm, and no one should be
running a Linux system with < 5.14 these days. Anyone running RHEL 6
should really be upgrading.
Oh, I do a Reply All that includes the author of the previous message.
Personally, I filter koha-devel, so if someone replies directly to me, I
see it before I check my filtered koha-devel folder. I figure other
people do the same so I do the same.

Smart matches where used a while back but marked as experimental and we
removed their only uses.
5.10 was required for defined-or, and Julian suggests we need 5.14
because of the use of /r.
PS is it me or the reply-to on this list puts the author of the previous

Those are good points. Personally, I’d like us to specify the Perl
version minimum based on actual usage as well. I just wonder how
best we determine what the minimum version should be (why 5.14?) and
where we specify that.
Should we be using “use 5.14.0” in plack.psgi for instance*? Or are
we just thinking about specifying the minimum in terms of the Debian
packages?
I wonder if there is a reliable list of features by Perl version
without reading through every delta listed at
https://perldoc.perl.org/index-history.html. There is something at
https://en.wikipedia.org/wiki/Perl_5_version_history.
Looking at “Non-destructive substitution (s///r)”, I see that’s only
used 2 (obvious) times and it’s in
Koha/SearchEngine/Elasticsearch/QueryBuilder.pm.
That said, that Wikipedia list doesn’t include the nuances of the
smart match operator, so it doesn’t seem very comprehensive.
I know Martin is interested in subroutine signatures but they look
experimental even in 5.30.0 according to
https://perldoc.perl.org/perlsub.html#Signatures.
Thoughts?

I agree with Martin we should be requiring newer versions when we
need them to (say) get better code or results.
And we should be consistent. Right now the minimum should be 5.14
and we are not making it clear to the users.
External library dependencies might be another reason to shift Perl
versions. So all of that is in the mix. And we try to be
conservative about this, specially when we pick external libraries
and QA should consider this.

I doubt we will need to worry about Perl 7 until it's available
in Debian. It's essentially 5.32 with some better defaults ( no
need to 'use strict' for example ). There will also be a
migration path from Perl 5 to Perl 7 ( but not from Perl 5 to
Perl 8 ). Perl 5 is expected to have about 10 years of continued
support.

Unlike Perl 6 (now known as Raku), Perl 7 appears to be an
actual backwards compatible successor to Perl 5:
https://www.perl.com/article/announcing-perl-7/. If you
don't want to read the link, "the bottom line" is "Perl 7 is
v5.32 with different settings. Your code should work if it’s
not a mess. Expect a user release within a year."

As for Perl 5.x versions, in the past, I've said let's stay
at 5.10 because of RHEL 6, but RHEL 6 is being retired
November 30, 2020 (with an "Extended Life Cycle Support
Add-On" available until June 30, 2024). I really don't think
we should be hamstrung by RHEL 6 anymore. RHEL 7 comes with
5.16 and RHEL 7's "Software Collections" can be used with
Perl 5.20 and Perl 5.24, although I don't think that the
RHEL 7 "Software Collections" can be used with the
#!/usr/bin/perl shebang (which would be used in CGI and
Plack's CGI emulation). That said, RHEL 8 is available now
and it comes with Perl 5.26.
Maybe we should just focus on Perl versions for supported
Debian/Ubuntu OSes, and if people want to use other OSes,
then they just need to upgrade to a newer version that
supports a newer Perl.
I think you can install Docker on RHEL 7, so that's another
consideration for people running Koha on non-Debian/Ubuntu
OSes. They can always just look at implementing a
container-based solution, which leverages Debian/Ubuntu as
the container OS.
So yeah... let's pick the lowest Perl on our supported
Debian/Ubuntu and have that be the minimum supported Perl.

Ubuntu 16.04.6 LTS (Xenial Xerus) was released February 28,
2019, has an "End of Standard Support" set at April 2021,
and "End of Life" of April
2024 -- where some package enhancements are ensured up to
the first of those dates, and *security* is ensured until
the second, i.e nearly another four years from now.
I obviously cannot speak for more than the organizations
with which I am involved, but basically we are all keeping
c++, php and perl based code on 16.04 LTS using Apache, and
have moved only python coding to 18.04.
However, we do use Nginx on 18.04 as a front end, proxying
to the 16.04 back ends. We are beginning to look at 20.04,
but first impressions of the transition are slightly painful.
As Mark mentions below, Xenial uses Perl 5.22.1-9ubuntu0.6.
I understand that the "1-9ubuntu0.6" denotes some fifty
patches and fixes on top of "basic 5.22" but not amounting
to 5.24. Just for completeness, 18.04 uses perl 5.26, and
20.04 comes with perl 5.30. However, from what I have
heard, the perl 5 branch has very few deprecated, let alone
removed, details, so backwards compatibility is on a fairly
firm footing. In fact, a quick look at 5.22 and 5.26 show
very much the same patches, but of course this may not apply
to non-core modules.
