No, of course not. It was introduced in 5.1 so that one could load
the engine from storage/innodb_plugin instead of the compiled-in engine
from storage/innobase. The tree had two versions of innodb.

Now MySQL has only one version of InnoDB, this switch can only be used
to load XtraDB instead.

But MariaDB is shipped with both XtraDB and InnoDB, and we want our
users to have a choice, they need --ignore-builtin-innodb.

Yes, I think so. LOCK TABLE ... LOW_PRIORITY WRITE is exactly identical
to LOCK TABLE ... WRITE, "LOW_PRIORITY" is ignored basically since MDLs
were introduced.

I don't know. Looks annoying to me. And it doesn't help anyway -
remember how many bug reports we've got like "MYSQLD DOESN'T START, IT
ONLY PRINTS `Fatal error: Please read Security section of the manual to
find out how to run mysqld as root!' WHAT SHOULD I DO?"

what do you mean?

it's a support for DATA DIRECTORY in InnoDB
please create a jira issue for 10.1.

No, that's badly implemented support for SHA256 password hashing.
We might want to do it - properly - if there will be a convincing reason
to.

It comes with test cases. Do they pass? Fail?
I suppose you can create a Jira issue for that, like you did for other
bugs.

See above.

Please create a jira task for 10.1 (adding ipv6/ipv4 functions like in
5.6). Unless we have it already, there are few ipv6-related tasks.
