regarding bug https://bugs.mageia.org/show_bug.cgi?id=5260
after talking with mariadb people and some others, i'm proposing to update mysql 5.5.10 to mariadb-5.5.23 in mga1. however, QA should extra-double-test the php-mysql dependency, as mariadb noted that php-mysql seems to have a very strict versioning scheme sometimes and having a new mysql provider without rebuilding php-mysql often fails... in case of no objections, i'll go ahead with this.
