When MariaDB was introduced to Fedora, it seemed like it eventually replaces MySQL and therefore the packages were designed so that `mysql` names were provided by MariaDB and MySQL was renamed to community-mysql. The both projects were drop-in replacements that time, so that design also helped smooth transition. Since then, a lot changed, MariaDB diverged from MySQL pretty lot, so it does not make sense to call it mysql (in RPM provides) any more. Also, the package name community-mysql are Fedora specific. Oracle upstream uses mysql-community, debian and RHEL use mysql names. To keep the naming convention more close to other Fedora-related clones, the proposal is to rename the MySQL packages to mysql-*.
Most (if not all) of the changes I propose here doesn't probabbly need such a formal process as Fedora Change is.
What I want is primarly to increase the visibility of the changes, and preserve those information in a permament document, allowing both users and maintainers to find this page both now, and in the future.
 
The changes described here are something I mostly <u>need</u> to be done, as a maintainer. They are my informed decisions backed up by the expertise I've gained over the many years I maintain these packages. I believe in the community discussion to focus primarly the technical aspects of the changes to help me to implement them correctly, bug-free, rather than whether to apply these changes at all.
 
Moreover, the changes here are described in a specific order. The order is based on how each task logicaly follow other. In case some of the changes would be found problematic, it might be dropped from the proposal (with all changes that directly relies on it)
 
 
 
 
 
'''Drop of the i686 architecture:'''
 
Both MariaDB and MySQL databases are huge pieces of software, taking hours to compile and test, taking up noticeable amount of system resources on our builders and any attached system (e.g. repositories). At the same time, I can hardly imagine anyone running those databases in production on i686 nowadays. <br>
Nothing, expect the 'mariadb' and 'community-mysql' packages, which provide the DB servers and client <u>application</u>. Drop of the other packages from the stack is not part of this proposal. So for now, packages like 'mariadb-connector-c' (which provides the client <u>library</u> 'libmariadb.so') and the ODBC or JAVA connectors will keep to build and ship their i686 variants. <br>
However the DB servers themselves are IMO expendable.
 
On top of the resources saved, I also keep finding bugs and issues, that are exclusive for the i686 architecture. They are more often than not in the tooling around, rather than the package itself, but it keeps needlessly devouring my time and energy anyway.
 
Last but not least, all maintainers are currently encouraged to drop i686 support, starting from leaf packages.<br>
https://fedoraproject.org/wiki/Changes/EncourageI686LeafRemoval
 
So I have to make sure the MariaDB and MySQL are leaf package on i686 architecture, so I can drop their i686 variants too.<br>
I've started the process by fixing https://bugzilla.redhat.com/show_bug.cgi?id=2241091
 
 
I use the following code to find out which packages requires which provides:
 
  #!/bin/bash
  mkdir -p RESULTS
  for REPO in "rawhide" "rpmfusion-free" "rpmfusion-nonfree" ; do
    for PROVIDE in "mariadb" "mariadb-devel" "mariadb-connector-c" "mariadb-connector-c-devel" "pkgconfig(mariadb)" "pkgconfig(libmariadb)" "mysql" "mysql-devel" "community-mysql" "community-mysql-devel" "pkgconfig(mysql)" ; do
      echo -e "\n\nREPO: $REPO ; PROVIDE: $PROVIDE";
      dnf -q --repo="$REPO" --repo="$REPO"-source repoquery --whatrequires "$PROVIDE" --alldeps | tee "./RESULTS/$REPO-$PROVIDE"
    done
  done
 
It show that other than the last few occurrences described in the bugzilla above, all is ready.
 
 
 
 
 
'''Rename package 'community-mysql' to 'mysql'''' <br>
and '''Stop providing 'mysql' symbols by package 'mariadb': '''
 
When MariaDB was introduced to Fedora, it seemed like it eventually replaces MySQL and therefore the packages were designed so that 'mysql' names were provided by MariaDB, and MySQL was renamed to community-mysql.
 
The both projects were drop-in replacements at that time, so that design helped the smooth transition.
Since then, a lot changed. First, those two databases developed different sets of features. The last "major major" version of MariaDB marked as a drop-in replacement is MariaDB 5.5.
From MariaDB 10.0, it is usually still easy to upgrade from one to another. <br>
https://mariadb.com/kb/en/mariadb-vs-mysql-compatibility/
 
Since MySQL 8.0 and circa MariaDB 10.5, the differences grew significantly and so it does not make sense anymore to provide 'mysql' names (= 'mysql' RPM `Provides:` ) by MariaDB package(s).
 
Moreover, the package name 'community-mysql' is Fedora specific. Oracle upstream uses 'mysql-community', Debian, RHEL and CentOS Stream use 'mysql'. From my experience I can say users usually search for 'mysql' name.
To keep the naming convention closer to Fedora-related clones, the proposal is to rename the MySQL packages from 'community-mysql' to 'mysql'.
 
This change will save me, the maintainer, noticeable amount of time and energy when cherry-picking commits and patches from Fedora to CentOS Stream and RHEL. <br>
And the more energy I save downstream, the more I can put into Fedora and upstream.
 
This change was being prepared to be proposed back for Fedora 37, but was left unfinished due to capacity reasons:
https://fedoraproject.org/wiki/Changes/MariaDB_MySQL_Renaming
 
 
 
 
 
'''Drop cross-installation functionality:'''
 
In Fedora, it is currently possible, on the packaging level, to cross install server of one DB with client of another. <br>
Specifically, you can install MariaDB server with MySQL client or MySQL server with MariaDB client.
 
I introduced this functionality to try it out, in hope of delivering a handy enhancement for the users. <br>
Sadly, the drawbacks outweights the positives. This behavior became a generator of elusive bugs I was never able to resolve. <br>
E.g.: https://bugzilla.redhat.com/show_bug.cgi?id=2026933
 
Moreover, as the MariaDB and MySQL projects diverged significantly (see the above point), it stopped to make sense around the time the MariaDB stopped to be drop-in replacement for MySQL.
 
AFAIK, Fedora is the only distribution I know of, which ever allowed such installation combination. <br>
I though it would be interesting, I tried it, I found out, now I want to end the experiment.
 
This change should not affect any other packages from the stack ('mariadb-connector-c', the ODBC, Python or JAVA connectors, ...) as they implement the API on their own and don't rely on the client <u>application</u>.
 
 
 
 
 
'''Switch to the versioned layout of MariaDB and MySQL packages:'''
 
I used the modularity heavily, as a package maintainer. <br>
It allowed me to ship alternative versions of MariaDB that I or the users wanted. During chnages of the default major version of MariaDB in Fedora, they served as a handy way for anyone to use them way before the change is implemented, or after it when the haven't adapted their systems to the new default version. I've regurarly selected the versions I maintain in CentOS Stream and RHEL - those which received the most care - and supported them fro the longest time as Fedora modules.
 
With Modularity retired https://fedoraproject.org/wiki/Changes/RetireModularity this ability has been lost.
 
When researching alternative approaches, only one seem to cover the same goals without too much of additional fuss. <br>
That is the "Multiple packages with the same base name": <br>
https://docs.fedoraproject.org/en-US/packaging-guidelines/Naming/#multiple
 
I want to change the packaging structure so the result will look as follows:
* The unversioned name ('mariadb') will become a meta-package
** It will point to the one versioned variant which I choose to be the default one for the given Fedora release
** It will provide all of the unversioned names for the versioned variant that is default for the given Fedora release, to minimize the changes visible to the users
* All other versions will have their own versoined package (e.g "mariadb10.5" "mariadb10.11") and will conflict with each other
 
This will allow for:
* users to keep using the unversioned names they are used to
* mainatiner to change the default version for a given Fedora release on a single, centralized place
* users to enjoy all of the features of the modularity I offered them, in a simpler way
* maintainer to add new versions quickly, without any need of changing the default version (other than adding new conflicts)
 
  Note:
  I specifically don't want the packages to be parallel installable. I only want them to be parallel available.
  That's why I didn't choose "Alternatives" as the solution:
  https://docs.fedoraproject.org/en-US/packaging-guidelines/Alternatives/
 
 
 
 
 
'''Introduce MariaDB 10.11 and MySQL 8.1'''
 
I would like to introduce MariaDB 10.11 and MySQL 8.1 into the Fedora.
 
Based on the previous point, it should be achieved without any user disturbance, as I won't change what is the default version in the distribution, I will just add an alternative for the users to choose from.
 
Proof of concept (needs additional work) for MariaDB 10.11 here: <br>
https://koji.fedoraproject.org/koji/taskinfo?taskID=102927697 <br>
https://src.fedoraproject.org/fork/mschorm/rpms/mariadb/commits/10.11-LTS
 
 
 
 
 
'''Change default MariaDB version in Fedora to 10.11'''
 
To keep being the leading edge distribution, I propose to update the default version of MariaDB in Fedora to the latest upstream LTS version, the MariaDB 10.11.
 
I have received a feedback on several occasions from various users that they would love to see this version in Fedora. Since I made a working proof of concept, I am confident that I will introduce the new version in time.
 
The MariaDB 10.6 LTS release has been skipped (was only available as a module) in Fedora, due to strategic reasons. At the time of early days of MariaDB 10.5 and 10.6, the MariaDB upstream changed their strategy of delivering the new releases. They switched to predictable quarterly releases, with new "major major" release every quarter. With this change, all releases are short-term releases with a support for only a single year. Some of the releases are made LTS, mostly based on the community feedback, discussion and demand. This all was new and unclear at the beginning, so we selected 10.5 LTS to be the main version maintained through Fedora, CentOS Stream and RHEL, so users from all three operating systems would contribute via reports to the health of the release and all those user's MariaDB would receive the same care. When the 10.6 was announced to become LTS, we didn't rush for it, both due to capacity reasons and to keep the bigger user-base advantage. We didn't know how long it would take for the next LTS to be announced.
 
Now, when the situation is clear, and the 10.11 was announced as the LTS, I believe it is appropriate to upgrade to this version in Fedora (and work is being strated downstream to again keep the bigger user-base advantage).
 
If the previous two changes are accepted and implemented, this change will be only a matter of updating the 'mariadb' meta-package to point to the 'mariadb10.11' as the Fedora default, instead of the 'mariadb10.5'

Describe what Users will see or notice, for example:
  - Packages are compressed more efficiently, making downloads and upgrades faster by 10%.
  - Kerberos tickets can be renewed automatically. Users will now have to authenticate less and become more productive. Credential management improvements mean a user can start their work day with a single sign on and not have to pause for reauthentication during their entire day.
- Libreoffice is one of the most commonly installed applications on Fedora and it is now available by default to help users "hit the ground running".
- Green has been scientifically proven to be the most relaxing color. The move to a default background color of green with green text will result in Fedora users being the most relaxed users of any operating system.
