blame the one which links PHP in 2017 still against libmysql at all
http://php.net/manual/de/book.mysqlnd.php

however, if you upgrade libraries it's pretty normal that you have to 
rebuild consumers of that libraries and hence you have 
build/staging/test systems before deployment - do you?

while i hate this useless rename and have currently no idea how to 
bootstrap the upgrade to 10.2 for other software than PHP and why it not 
simply has symlinks to satisfy already compiled dependencies... upgrade 
to 10.2 within a dist-upgrade is a nogo

if you just jump blindly to a new major release, don't test anything, 
don't inform yourself and mix distribution and other packages and to 
make it worst throw self compiled stuff not properly packaged in the mix 
you are the one to blame and nonody else

Hello everybody!

Since MariaDB 10.2 is finally stable and I resolved all issues that 
blocked it for Fedora, I'd like to propose an update for Rawhide.

Current version of MariaDB: 10.1.24
Update planned to: 10.2.6 (or newer)

*This change introduces change of library name from "libmysqlclient.so" 
to "libmariadb.so".*
*There are many dependant packages affected.*

The current (optimistic) plan is to deliver the update before Fedora 27 
mass rebuild <https://fedoraproject.org/wiki/Releases/27/Schedule> at 
12.7.2017.
Either the rebuild of all depending packages is inevitable.

We actively track the issue here 
<https://bugzilla.redhat.com/show_bug.cgi?id=1467297>. There is also a 
list of affected packages.
We have a work repository in COPR, where you can find builds of your 
packages here 
<https://copr.fedorainfracloud.org/coprs/g/db-sig/mariadb-10.2/packages/>.

We go through all of the issues and we are trying to solve all of those, 
which are caused by the library change. More information will appear in 
bugzillas connected to the tracker.

Issues are also consulted with MariaDB upstream.
I was told, that there should be strong API and ABI compatibility.

-

Notes:
  - this means also drop of symlinks to "libmysqlclient.so.18.0.0" library.
  - the version of the library in MariaDB 10.2.6 is "mariadb.so.3", 
however in mariadb-connector-c it is only "mariadb.so.2". That should 
sync in next big update in about a month, I believe.

Feel free to ask any questinos here or in tracker BZ, I'll try to search 
for all answers.
