Description:
It is not possible to use mysql-test-run.pl to start a server with a non-default --maria-block-size option:

perl mysql-test-run.pl --start-and-exit --mysqld=--maria-block-size=1K

error log says:

080928 20:40:10 [ERROR] mysqld: Got error 'Block size in control file (8192) is different than given maria_block_size: 1024' when trying to use maria control file '/build/bzr/6.0-maria/mysql-test/var/master-data/maria_log_control'

This is possibly because mysqld is started once before it is started for a second and final time in the same dir. The first server start is with default maria settings and causes a default maria_log_control file to be created. The second start thus fails.

This prevents full Maria testing using mysql-test-run.pl .

How to repeat:
perl mysql-test-run.pl --start-and-exit --mysqld=--maria-block-size=1K

Suggested fix:
Either start mysqld only once or start it with the same maria options both times.

Feels like mtr.pl is used in a "hackish" way using --start-and-exit, which  does not allow it to have full control of the test cycle.

Think we should discuss how to implement these tests as .test files.

Starting the server with --start-and-exit is a first stage for many testing frameworks which perform tests which can not be expressed with a .test/.result scenario, e.g. the Random Query Generator.

Thank you for a bug report. Verified also with mysql-6.0 main tree from bzr.

A fix for this has been pushed to mysql-maria.

Test suite changes. No changelog entry needed.
