LP #1077070: innobackupex gets stuck if /tmp is out of space

Description

**Reported in Launchpad by Vadim Tkachenko last update 26-03-2013 11:33:24

this is not critical, but could be very confusing if you try to figure out why backup is not working.

if /tmp partition runs out of space , innobackupex gets stuck.
the reason is it call mysql with redirects to /tmp

sh -c mysql --defaults-file='/etc/my.cnf' --socket='/tmp/mysql.sock' --unbuffered – >/tmp/qwtrwer 2>/tmp/aIuldPGEzc

in this case Innobackupex gets into infinity loop in mysql_ping function,
as it tries to read from mysql_stdout, and it is always empty.

Does not apply to 2.1 as mysql_stdout is not used there. I think it is reasonable to not fix it in lower versions.

I'd normally set this to High, but fixing this essentially involves a large rewrite/replacement of innobackupex, which is more of Wishlist than anything else.

Not a Bug
