[Mageia-dev] HEADSUP: mariadb available for testing

Tue Nov 29 00:21:04 CET 2011

Hi,
+
+in order to get more testing, i've decided to submit to cauldron core/release, 
+however there lies a problem:
+
+Since everything is almost exact with mysql, same files and such, there are 
+some library conflicts which would present always a choice if we want both 
+mysql and mariadb (in particular libmysqlclient.so.X). Since we also want this 
+really used at build/link time one of both versions should be used.
+
+considering that mariadb mysql client works perfectly for both mysql and 
+mariadb. and that mysql mysql-client may not work perfectly for local servers 
+due to the my.cnf file being used for both client and server (mysql client is 
+supported for remote mariadb servers), I'd like to use the mariadb client 
+packages.
+
+The way I see it, there are 2 possibilities:
+A. I remove the mysql-client, libmysqlclient, mysql-common and assorted 
+packages from mysql, and provide them with mariadb, since libmysqlclient is 
+drop-in replacable (same library ABI and such), there is not 100% requirement 
+of rebuilding all libmysqlclient dependant programs.
+
+advantages:
+ - both mariadb and mysql servers are present, people can choose
+disadvantages:
+ - more QA
+ - more work for me
+
+B. We drop mysql completely and submit mariadb
+
+advantages:
+ - less work for me
+ - less work for QA
+disadvantages:
+ - mysql is completely gone.
+
+If I get to choose, i'd know which one i would choose, but I'd like some 
+feedback on this point.
+
+Some more bordering information:
+ - mariadb has XtraDB, which is essentially a patched InnoDB (it also supplies 
+an exact vanilla InnoDB as a plugin)
+ - mariadb still has myISAM support
+ - mariadb has as a default storage engine Aria (which can be used either as 
+transactional and as non-transactional)
+ - the files are exactly the same as mysql, it's still mysqld, mysql for client 
+so upgrading issues should be minimal, but still tested, of course.
+
+so please, test mariadb, build stuff against lib64mariadbclient18 , and give 
+opinion to which option to choose: A/B .
