	On FreeBSD, perl isn't in /usr/bin, its in /usr/local/bin or
elsewhere in the path.
Like storage/{maria/unittest/,}ma_test_* , we use /usr/bin/env to
find perl and run it.

This program tries to find all limits and capabilities for a SQL
 | 
						||
server.  As it will use the server in some 'unexpected' ways, one
 | 
						||
shouldn\'t have anything important running on it at the same time this
 | 
						||
program runs!  There is a slight chance that something unexpected may
 | 
						||
happen....
 | 
						||
 | 
						||
As all used queries are legal according to some SQL standard. any
 | 
						||
reasonable SQL server should be able to run this test without any
 | 
						||
problems.
 | 
						||
 | 
						||
All questions is cached in $opt_dir/'server_name'[-suffix].cfg that
 | 
						||
future runs will use limits found in previous runs. Remove this file
 | 
						||
if you want to find the current limits for your version of the
 | 
						||
database server.
 | 
						||
 | 
						||
This program uses some table names while testing things. If you have any
 | 
						||
tables with the name of 'crash_me' or 'crash_qxxxx' where 'x' is a number,
 | 
						||
they will be deleted by this test!
 | 
						||
 | 
						||
$0 takes the following options:
 | 
						||
 | 
						||
--help or --Information
 | 
						||
  Shows this help
 | 
						||
 | 
						||
--batch-mode
 | 
						||
  Don\'t ask any questions, quit on errors.
 | 
						||
 | 
						||
--config-file='filename'
 | 
						||
  Read limit results from specific file
 | 
						||
 | 
						||
--comment='some comment'
 | 
						||
  Add this comment to the crash-me limit file
 | 
						||
 | 
						||
--check-server
 | 
						||
  Do a new connection to the server every time crash-me checks if the server
 | 
						||
  is alive.  This can help in cases where the server starts returning wrong
 | 
						||
  data because of an earlier select.
 | 
						||
 | 
						||
--database='database' (Default $opt_database)
 | 
						||
  Create test tables in this database.
 | 
						||
 | 
						||
--dir='limits'
 | 
						||
  Save crash-me output in this directory
 | 
						||
 | 
						||
--debug
 | 
						||
  Lots of printing to help debugging if something goes wrong.
 | 
						||
 | 
						||
--fix-limit-file
 | 
						||
  Reformat the crash-me limit file.  crash-me is not run!
 | 
						||
 | 
						||
--force
 | 
						||
  Start test at once, without a warning screen and without questions.
 | 
						||
  This is a option for the very brave.
 | 
						||
  Use this in your cron scripts to test your database every night.
 | 
						||
 | 
						||
--log-all-queries
 | 
						||
  Prints all queries that are executed. Mostly used for debugging crash-me.
 | 
						||
 | 
						||
--log-queries-to-file='filename'
 | 
						||
  Log full queries to file.
 | 
						||
 | 
						||
--host='hostname' (Default $opt_host)
 | 
						||
  Run tests on this host.
 | 
						||
 | 
						||
--password='password'
 | 
						||
  Password for the current user.
 | 
						||
   
 | 
						||
--restart
 | 
						||
  Save states during each limit tests. This will make it possible to continue
 | 
						||
  by restarting with the same options if there is some bug in the DBI or
 | 
						||
  DBD driver that caused $0 to die!
 | 
						||
 | 
						||
--server='server name'  (Default $opt_server)
 | 
						||
  Run the test on the given server.
 | 
						||
  Known servers names are: Access, Adabas, AdabasD, Empress, Oracle, 
 | 
						||
  Informix, DB2, Mimer, mSQL, MS-SQL, MySQL, Pg, Solid or Sybase.
 | 
						||
  For others $0 can\'t report the server version.
 | 
						||
 | 
						||
--suffix='suffix' (Default '')
 | 
						||
  Add suffix to the output filename. For instance if you run crash-me like
 | 
						||
  "crash-me --suffix="myisam",
 | 
						||
  then output filename will look "mysql-myisam.cfg".
 | 
						||
 | 
						||
--user='user_name'
 | 
						||
  User name to log into the SQL server.
 | 
						||
 | 
						||
--db-start-cmd='command to restart server'
 | 
						||
  Automaticly restarts server with this command if the database server dies.
 | 
						||
 | 
						||
--sleep='time in seconds' (Default $opt_sleep)
 | 
						||
  Wait this long before restarting server.
 | 
						||
 | 
						||
--verbose
 | 
						||
  Log into the result file queries performed for determination parameter value
 | 
						||
  This causes rows starting with ' ###' to be logged into the .cnf file
 | 
						||
 | 
						||
--noverbose
 | 
						||
  Don't log '###' quries to the .cnf file.

Some of the tests you are about to execute may require a lot of

memory.  Your tests WILL adversely affect system performance. It\'s

not uncommon that either this crash-me test program, or the actual

database back-end, will DIE with an out-of-memory error. So might

any other program on your system if it requests more memory at the

wrong time.
 | 
						||
 | 
						||
Note also that while crash-me tries to find limits for the database server
 |

it will make a lot of queries that can\'t be categorized as \'normal\'.  It\'s

not unlikely that crash-me finds some limit bug in your server so if you

run this test you have to be prepared that your server may die during it!

you agree to the above!
