Okay, pushed with no further MSVC changes, after doing a round on CI.

Looks reasonable just by eyeball, did not test.

Agreed --- the MSVC scripts are on a pretty short leash now.
Not clear it's worth fixing them for this point.  If we've
failed to get rid of them by the time v16 release approaches,
maybe it'd be worth doing something then.

In that case, here is a quick update with commit message. Not yet any
change for MSVC, but I can put together something later.

Since we're much less willing to support older Windows and Visual
Studio versions, maybe it's low-enough risk defer the check to the
Meson conversion? I understand our MSVC process will then go away much
more quickly than autoconf...

Subject: [PATCH v2] Bump minimum Perl version to 5.14

The oldest vendor-shipped Perl in the buildfarm is 5.14.2, which is the
last version that Debian Wheezy shipped. That OS is EOL, but we keep
it running because there is no other convenient way to test certain
non-mainstream 32-bit platforms. There is no bugfix in the .2 release
that is required, and yet it's also not the latest minor release --
that would be 5.14.4. To clarify the situation, we also have arranged the
buildfarm to test 5.14.0. That allows configure scripts and documentation
to state 5.14 without fine print.

Discussion: https://www.postgresql.org/message-id/20220902181553.ev4pgzhubhdkg...@awork3.anarazel.de

As soon as I hit send, it occurred to me that we don't check the perl
version on Windows, since (I seem to recall) 5.8.3 was too old to be
an option on that platform. We'll have to add a new check somewhere.

Yeah, that seems like a reasonable new minimum for Perl.  I might
see about setting up an animal running 5.14.0, just so we can say

5.14 would be a trivial lift as far as the buildfarm is concerned. The Debian
7 animals couldn't trivially be updated to a newer perl. It's from 2013-05-04,
so I wouldn't feel bad about dropping support for it - but probably wouldn't
personally bother just for this.

Andres Freund

minimum perl version

Hi,

Split off from the meson thread at

5.8.3 is from 2004-Jan-14, that's impressive :). I don't see any benefit in
setting up a buildfarm animal running that old a version.

For the meson stuff it'd suffice to set 5.9.3. as the minimum version for
plperl (or I could try to work around it). However, supporting a perl version
from 2006-Jan-28 doesn't strike me as particularly useful either.


Relevent somewhat recent discussion / work:
https://postgr.es/m/87y278s6iq.fsf%40wibble.ilmari.org
https://www.postgresql.org/message-id/E1mYY6Z-0006OL-QN%40gemulon.postgresql.org


I looked at which buildfarm animals currently use 5.14 (mentioned by John),
and it's frogfish, snapper and skate. The latter two do build with plperl.


I started a query on the buildfarm machine to collect the perl versions, but
it's just awfully slow...

Greetings,

Andres Freund
