Hi all,
See attached the draft news item for MySQL/MariaDB dropping PBXT
support.
I would like to drop the blocks into the tree not later than June 3rd.
I think it should affect very few users, as PBXT was a niche feature.
This should clear us to get MySQL/MariaDB 5.5 into stable.

Title: MySQL/MariaDB packages dropping support for PrimeBase (PBXT) engine

The PBXT/PrimeBase engine is unsupported upstream in MySQL & MariaDB for some
time now [1]. 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/mysql-cluster-5.5 pbxt # overlay
>=dev-db/mariadb-5.5 pbxt
>=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 should convert the tables
to another format before upgrading to MySQL/MariaDB 5.5, as the tables will
otherwise become inaccessible.
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.

Too long, maximum 44 characters according to GLEP 42. The above will even
be truncated by eselect news.

from the draft:
"All users who have data stored in PBXT-backed tables should convert the
tables to another format before upgrading to MySQL/MariaDB 5.5, as the
tables will otherwise become inaccessible. "
s/before/BEFORE/
it should be very visible.
Also, is it possible to halt the merge into filesystem if some PBXT
tables exists in ${MY_DATADIR}?
Not that I like it but maybe users prefer this to be forced to downgrade
after.

Will do.

I'll meet in the middle, and display a big warning if there are any .xt
files in MY_DATADIR. I will NOT halt the upgrade.
