Current status
- Targeted release: Fedora 32
- Last updated: 2020-03-29
- Tracker bug: #1756468
- Release Notes tracking: #391
- Release Engineering ticket: https://pagure.io/releng/issue/8783
Detailed Description
Update of MariaDB package in Fedora from 10.3 version to 10.4 version.
Benefit to Fedora
I'm cooperating with the upstream to bring the latest stable software to Fedora users.
10.4 series introduces number of enhancements, which cannot be found in previous series. Apart from that, MariaDB Galera Cluster has been significantly reworked and enhanced. (galera 3 updated to galera 4)
Scope
- Proposal owners:
- Prepare MariaDB 10.4 as a module for Rawhide and atleast one stable Fedora release (done)
- Prepare MariaDB 10.3 as a module for Rawhide, so there would be a failover in case of problems (done)
- Release MariaDB 10.4 to Rawhide (blocked by #1724283; solving with upstream)
- Check software that requires or depends on 'mariadb' or 'galera' package for incompatibilities
- Gather user input on the changes between MariaDB 10.3 and 10.4
- Other developers: N/A (not a System Wide Change)
- Release engineering: (a check of an impact with Release Engineering is needed)
- List of deliverables: N/A (not a System Wide Change)
- Policies and guidelines: N/A (not a System Wide Change)
- Trademark approval: N/A (not needed for this Change)
Upgrade/compatibility impact
The MariaDB client library is compatible, so the shouldn't be any issues and / or need for rebuild of dependent packages.
MariaDB 10.4 defaults to using unix_socket password authentication plugin.
The old behaviour can still be invoked in several ways, so it shouldn't be an issue for those who can't adapt to it just yet.

Galera package bumped version from 25.3 to 25.4 which introduces bigger changes. However since no other project in Fedora than MariaDB use Galera, I don't expect any issue here.
UPDATE (02/2020)
MariaDB 10.4.12 is now available in Fedora Rawhide, 32 and as a module for Fedora 30 and later. Currently, there is a known issue, affecting user logins to the DB: RHBZ#1796106. We are working to resolve this issue before F32 will be released.
UPDATE (03/2020)
The issue above was resolved. Packages containing the fix are now in F32 stable repositories.
How To Test
Usual testing as when upgrading between major MariaDB versions.
Test that all other software runs well with MariaDB 10.4. Report any issues, so I can reach the different upstreams and check if they plan update their software to support MariaDB 10.4 and when.
User Experience
The users will have to upgrade their databases the same way as between major MariaDB versions.
If the users want to stick with MariaDB for a little longer, I provide MariaDB 10.3 module. If the users want to test it beforehand, I provide MariaDB 10.4 module.
Dependencies
There should be absolute minimum amountof packages, that use MariaDB as a BuildRequires. Since the separation of MariaDB client library, only packages that build server plugins may use MariaDB as a BuildRequires.
Since the client library ('mariadb-connector-c') is not changing, dependent software should work fine.
Contingency Plan
Modules will provide the functional version of MariaDB 10.3, available to all users.
- Contingency mechanism: Fedora Modules available
- Contingency deadline: beta freeze
- Blocks release? N/A (not a System Wide Change)
- Blocks product? N/A (not a System Wide Change)
