From 1f669d708b4f07d7f4d9b9008f2231dc1d4b80bb Mon Sep 17 00:00:00 2001 From: Saiful Amin Date: Thu, 26 Feb 2026 13:59:44 +0000 Subject: [PATCH] Bug 41353: koha-dump failing on mysqldump PROCESS privileges 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-.sql.gz | tail 9.
