Current status
- Targeted release: Fedora 29
- Last updated: 2020-02-19
- Tracker bug: #1582618
- Release Notes tracking: #174
Detailed Description
Update of MySQL package in Fedora from 5.7 version to 8.0 version.
Benefit to Fedora
I'm cooperating with the upstream to bring the latest stable software to Fedora users.
Scope
- Proposal owners:
- Release MySQL 8.0.11 to Rawhide (done)
- Check software that requires community-mysql package (done, only mysql-connector-odbc)
- Gather user input on the changes between mysql 5.7 and 8.0
- Other developers: N/A (not a System Wide Change)
- Release engineering: Releng issue number 7486 (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 'libmysqld' embedded server library has been removed by upstream. (Though, applications requiring 'libmysqld' can be (re)built against mariadb-embedded-devel, which Provides mysql-embedded-devel and ships a libmysqld.so symlink to libmariadbd.so.*.)
Downgrade from MySQL 8 to MySQL 5.7 is not supported.
How To Test
Usual testing as when upgrading between major MySQL versions.
Test that all other software runs well with MySQL 8. Report any issues, so I can reach the different upstreams and check if they plan update their software to support MySQL 8 and when.
User Experience
The users will have to migrate their applications and databases, if the y want to use MySQL 8.
If the users want to stick with MySQL 5.7 for a little longer, I'm providing COPR repo with MySQL 5.7 built from f28 branch for Rawhide.
Also, module with MySQL 5.7 is planned.
Dependencies
mysql-connector-odbc
- also maintained by me
- currently FTBFS against the MySQL 8.0.11, working on the fix. However for MariaDB there is mariadb-connector-odbc, so users don't depend on this piece of software.
There may be more software, which does not support MySQL 8 yet. For such occurences, COPR repo with MySQL 5.7 was created.
Contingency Plan
The COPR repository until F29 freeze seems enough to me. For F29, there should be a module available with MySQL 5.7 to cover users that can't / don't want to upgrade.
- Contingency mechanism: COPR and Module with MySQL 5.7 available
- Contingency deadline: beta freeze
- Blocks release? N/A (not a System Wide Change)
- Blocks product? N/A (not a System Wide Change)
