It is no longer built in the upstream MariaDB 5.5 binaries[2][3] +and if it is enabled in a source build, it fails many tests [4]. + +In light of this, the MySQL team has decided to mask it in +profiles/base/package.use.mask for all relevant packages. +>=dev-db/mysql-5.5 pbxt +>=dev-db/mariadb-5.5 pbxt +>=dev-db/mysql-cluster-5.5 pbxt # overlay +>=dev-db/mariadb-galera-5.5 pbxt # overlay +>=dev-db/percona-server-5.5 pbxt # overlay +>=dev-db/google-mysql-5.5 pbxt # overlay + +All users who have data stored in PBXT-backed tables MUST convert the tables +to another format BEFORE upgrading to MySQL/MariaDB 5.5, as the tables will +become inaccessible otherwise. + +We will continue to allow it to be built in the 5.0/5.1 series, to make the +above data migration easy, but we strongly encourage all users to move their +data out of the PBXT engine. + +If you need to check for PBXT tables easily, look in your MySQL/MariaDB +datadir for any files with a .xt extension. + +1. https://lists.launchpad.net/pbxt-discuss/msg00134.html +2. http://www.bytebot.net/blog/archives/2012/05/25/mariadb-5-5-has-deprecated-pbxt +3. https://kb.askmonty.org/en/about-pbxt/ +4. https://bugs.gentoo.org/show_bug.cgi?id=471616#c1 |
