new feature: version info

[Matthew Kent]

Hi guys!

As we continue to expand the number of mysql versions we are using I'm finding myself in a position where I want to include the version information for mysql/xtrabackup/innobackex running at the time of backup. This is easy to write out to a file but impossible to include with the backup right now. To keep this tightly coupled with the backup data I'd like to include it within the copy/tar as well so it's impossible to lose.

For consideration is a patch to do just that, it adds a file, xtrabackup_backup_info, within the backup that includes the mysql, xtrabackup and innobackupex versions.

Wrote this against 2.0.5. Passes testrun.sh and includes it's own tests.

Thanks for the patch! I'd like us to look at including this in the XtraBackup 2.1 tree.

Thanks! Looks like it's marked as fix committed but I can't see it upstream (or I'm misunderstanding how launchpad works). Is this still pending review?

Ping?

Thank you for the patch. It is still pending review.

Hi Matt,

This request is closely related to https://blueprints.launchpad.net/percona-xtrabackup/+spec/history-on-the-server. I've updated it with some comments referencing this bug and the contributed patch. I think it would be reasonable to implement this request along with the history-on-the-server BP.

Thanks.

Rebased against 2.1.5.

[Alexey Kopytov (akopytov)]

This has been implemented along with with https://blueprints.launchpad.net/percona-xtrabackup/+spec/history-on-the-server and will be available in XtraBackup 2.2.
