ECLASS VARIABLES

MYSQL_PV_MAJOR = "$(get_version_component_range 1-2 ${PV})"
Upstream MySQL considers the first two parts of the version number to be the major version. Upgrades that change major version should always run mysql_upgrade.
MYSQL_VERSION_ID
MYSQL_VERSION_ID will be: major * 10e6 + minor * 10e4 + micro * 10e2 + gentoo revision number, all [0..99] This is an important part, because many of the choices the MySQL ebuild will do depend on this variable. In particular, the code below transforms a $PVR like "5.0.18-r3" in "5001803" We also strip off upstream's trailing letter that they use to respin tarballs
MYSQL_COMMUNITY_FEATURES
Specifiy if community features are available. Possible values are 1 (yes) and 0 (no). Community features are available in mysql-community AND in the re-merged mysql-5.0.82 and newer
XTRADB_VER = "${XTRADB_VER}"
Version of the XTRADB storage engine
PERCONA_VER = "${PERCONA_VER}"
Designation by PERCONA for a MySQL version to apply an XTRADB release
