# This script runs the transactional stress test "stress_tx_rr" against the
# transactional storage engine and looks for errors in two log files:
#   var/stress/<timestamp>/mysql-stress-test.log
#   var/log/master.err
#
# The script assumes current working dir is mysql-test/.
#
# Regarding the server error log, currently only error lines containing the 
# string "Error:" will be reported as a critical error, in addition to signs
# of crashes.
#
# In the stress test log, all lines matching the regex "S\d:" (denoting an
# error with a specified severity) will be reported as errors.
#
# Error information including the full server log in the case of server crash
# is output to standard out.
#
# This script is and should be silent if no errors are detected.

--engine=<engine>
    The engine used to run the test. \<engine\> needs to be provided exactly as 
    it is reprted in the SHOW ENGINES comand.
    EXCEPTION: In order to use the InnoDB plugin, specify 'InnoDB_plugin'
  Required option.

--duration=nn
    The time the test should run for in seconds. Defaut value is 600 seconds (10 minutes).
  Optional parameter

--threads=nn
    The number of clients used by the test driver. Defaut value is 10.
  Optional parameter

--try
    Do not run the actual test but show what will be run
  Optional parameter

\nThis test is can be run against any transactional engine. However scripts need to be modifed in order
to support such engines (support to InnoDB is provided as an example).
In order to add support for a new engine, you will need to modify scripts as follows:
   1) cd to INSTALL_DIR/mysql-test/suite/engines/rr_trx
   2) Modify the 'run_stress_rr.pl' file by adding an 'elsif' section for your engine and have it
      include specifc values required to be passed as startup parameters to the MySQL server by
      specifying them using "--mysqld" options (see InnoDB example).
   3) Copy the 'init_innodb.txt' file to 'init_<engine>.txt file and change its content to be "init_<engine>".
   4) In the 't' directory copy the "init_innodb.test" file to "init_\<engine\>.test" and change the value of
      the '\$engine' variable to \<engine\>.
   5) In the 'r' directory copy "the init_innodb.result" file to "init_\<engine\>.result" and change refrences
      to 'InnoDB' to \<engine\>.
