Hi Giuseppe
I'm cross-posting to maria-discuss since this is now a non-technical
discussion. Please remove maria-developers when replying.

Of course, all of the MariaDB source code is available as GPL, just
like for MySQL. Sun is not prohibited from using it under the GPL,
just like we are using MySQL code.

We've made some adjustments, but yes, apparently it is one of the best
contributor agreements around, the community seems to think. That's
why we use it.

Actually, it is very important that MariaDB copyrights are pooled to
one owner, we could get into trouble if we didn't do that. (I won't
give the details, so as not to give any ideas.)
Same is true for XtraDB, where we have advised Percona to pool the
copryights from any non-Percona contributors. It's not like we (MP)
want to own everything, but somebody has to do it.
Personally my first motivation in favor of pooling copyrights was
however entirely benevolent towards MySQL and its users. By having the
copyrights pooled in one place (rather than just going all GPL), we
are able to assign the code back to Sun (if we so agree), and I'd
really like to do that so that all MySQL users, also the commercial
licensees would benefit from the MariaDB work.

Hi!
We're getting a compile error when trying to compile PBXT+Maria on ppc MacOS X:

looking at the bottom there, one sees:

Is PBXT expected to work on MacOS X G5?

Why does UNION ALL use a temp table? Many users are surprised by this.
It would be faster to return rows from each branch of a UNION ALL
query directly to the network.

Does MariaDB have any plans to support explain for
insert/update/delete/replace/CTAS? There have been feature requests
open for a very long time on official MySQL without any progress. I
have had a few problems in production from 'bad' delete statements
that had a very different plan than the select statement with the same
where clause. The only way to check for a bad plan today is to use
SHOW INNODB STATUS to determine whether the statement locks all rows
in a table.
