Problem:
Starting from MySQL 5.7.31 and MySQL 8.0.20, mysqldump requires the
PROCESS privilege to access tablespace metadata by default. Without
this privilege, backup operations fail with permission errors.
Solution:
Add the --no-tablespaces flag to the dbflag variable. This prevents
mysqldump from attempting to access tablespace metadata, allowing
backups to complete successfully without requiring the PROCESS privilege.
Test Plan:
1. Set up a MySQL instance (5.7.31+ or 8.0.20+) without PROCESS privilege for the Koha database user
2. Run the koha-dump script for a Koha instance:
sudo koha-dump kohadev
3. Notice the backup fails with a PROCESS privilege error
4. Apply the patch
5. Copy debian/scripts/koha-dump to /usr/sbin/koha-dump
6. Repeat step 2
7. Notice the backup now completes successfully without permission errors
8. Test restoring the dump to ensure it's valid:
zcat /var/spool/koha/kohadev/kohadev-<date>.sql.gz | tail
