This directory contains scripts for manipulating of replication suite (rpl).

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.

Binlog checksum testing
=======================

1. How it works.
The script copies a <suite> to directory <suite>_checksum,
collects test case names for t/ directory (except tests from
disabled def), randomly choose 90% of tests and add them
to disabled.def.
It means that mtr will run only 10% of random tests from each
suite.
At end the script run mtr:
./mysql-test-run.pl --suite=aaa_checksum,bbb_checksum \
    --mysqld=--binlog-checksum=CRC32 arg1 ... argN

aaa,bbb 	- suite names from --suite option
arg1,argN	- other command-line arguments of checksum.pl

2. The options:

--suite=suite1,suite2.  Mandatory option. The list of suites for
    binlog checksum testing.

--percent=N, where N is 1..99. Percent of running tests.
