Blackhole slave testing
=======================

Blackhole slave means intermediate server between master and slave by
schema:

master -> blackhole slave -> slave

The script bhs.pl copies mysql-test/suite/rpl into mysql-test/suite/rpl_bhs 
and updates some files there for adding blackhole slave. After that bhs.pl
calls mysql-test-run.pl.
The script bhs.pl requires one argument in command line: 
--trans-test-list=<test list for update> (currently it is 
update_test_cases)

Other arguments in command line will be used by mysql-test-run.pl

The behavior of update is controlled by bollowing files:

bhs/update_test_cases - list of files for update. Each line contains path to 
test case (use asteriks instead filename if you want to update all files in a 
directory) and file with rules

bhs/default.rules - default rules for update.
