Please note the on Debian MariaDB 5.5. and 10.0 already builds fine and all build tests also pass for PPC64. The packaging source is at http://anonscm.debian.org/cgit/pkg-mysql/mariadb-10.0.git and http://anonscm.debian.org/cgit/pkg-mysql/mariadb-5.5.git but the Debian packaging changes havn't fully been upstreamed simply due to lack of time due to other priorities in Debiian packaging at the moment.

As noted in Stewart Smith's LCA2015 talk http://youtu.be/KxTNMoOTMIA / http://lca2015.linux.org.au/schedule/30203/view_talk?day=wednesday the test suite didn't adequately test the boundaries and memory barriers.

MDEV-7004 says some are merged in 10.1

It sounds like 5.5 / 10.0 are significantly unreliable without patches.

Comment by Sergey Vojtovich [ 2015-01-18 ]

danblack, MDEV-7004 is all about scalability and doesn't affect reliability in any way. And exactly reliability was the reason not to implement them in 5.5 and 10.0.
