Issue Summary

Follow up task from BSERV-13507: we would like to update the perl script to create sockets in IPv6 environment for customers running Bitbucket 8.0+ on MacOS. This includes an update to release notes of the version that this releases in.

In Bitbucket 8.0+ hook-callback.pl has been replaced by a native programme that no longer relies on the Perl script for production environment. But this script is still used in 8.0+ for running on MacOS (which is only supported for evaluations and plugin development).

We want to update this in a future minor version of Bitbucket along with a corresponding increase in the minimum Perl version required.

This is reproducible on Data Center: yes

Steps to Reproduce

1. see BSERV-13507

Expected Results

$BITBUCKET_HOME/bin/git-hooks/hook-callback.pl should be able to create a socket with an IPv6 host address.

Actual Results

Trying to clone or push into a repository would fail.

Workaround

Suggestion:

Consider replacing IO::Socket::INET with IO::Socket::IP, which is capable of handling IPv4 and IPv6 addresses, since INET6 has deprecated.

Original workaround:

Modify the $BITBUCKET_HOME/bin/git-hooks/hook-callback.pl to use IPv6

Change the below line on $BITBUCKET_HOME/bin/git-hooks/hook-callback.pl

my $socket = new IO::Socket::INET

It should be replaced to:

my $socket = new IO::Socket::INET6

(also added use IO::Socket::INET6; at top of hook-callback.pl)

Please Note this isn't a permanent setting everytime the Bitbucket service is restarted the hook-callback.pl is regenerated by the Bitbucket so it must be modified every time after the restart.
