[21.10 FEAT] Update PCRE2 for JIT and Performance Improvements on s390x

[bugproxy]

PCRE2 version 10.37 as available from https://ftp.pcre.org/pub/pcre/
contains the enablement of the JIT and provides some performance improvements

Version 10.38 to be released in November or December 2021 will contain the complete implementation with full JIT performance.

To pick up the changes please configure with "--enable-jit" for s390x.

It may be beneficial to rebuild certain dependent packages after that change, such as haproxy.

I've created a patched new version and created this debdiff.

[Frank Heimes (fheimes)]

I've also successfully compiled the new patched package cross-platform in this PPA:
https://launchpad.net/~fheimes/+archive/ubuntu/lp1931857/+packages

[Frank Heimes (fheimes)]

I've also build the patched file locally on s390x (where also the build flags were changed);
and successfully ran the provided tests.

Since the updated pcre2 version just landed in proposed:
pcre2 | 10.37-0ubuntu1 | impish-proposed
I'm updating this ticket to Fix Committed.

The attachment "pcre2.debdiff" seems to be a debdiff. The ubuntu-sponsors team has been subscribed to the bug report so that they can review and hopefully sponsor the debdiff. If the attachment isn't a patch, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are member of the ~ubuntu-sponsors, unsubscribe the team.

This upload is currently stuck in -proposed due to an autokpkgtest failure in mariadb-10.5:

/usr/bin/mysqltest: error while loading shared libraries: libpcre2-posix.so.2: cannot open shared object file: No such file or directory

I've found that upstream changed the SONAME from libpcre2-posix.so.2 to libpcre2-posix.so.3, due to several dropped symbols. The binary package libpcre2-posix2 should be renamed to libpcre2-posix3 and reverse-dependencies hardlink and mariadb-10.5 need to be rebuilt.

I have tested all of this in my PPA and the rebuilt mariadb-10.5's autopkgtest now pass there.

I'd like an ack from release team before I go ahead and complete this transition.

+1 for the release team, this is a small self-contained transition for a change already in -proposed as of feature freeze.

Uploaded:

Now waiting for migration (blocked by glibc).
