mariadb/mysql-test/README
Michael Widenius e6c45f5e1f - Reduced memory requirements for mysqltest to 1/4.th This also gave a speedup for 5x for some tests.
- Reduced memory usage from safe_mutex.
- Fixed problem with failing tests that could not restart mysqld becasue the port was reserved
- More DBUG information
- Fixed bug where bitmap_set_prefix() wrote over buffer area.
- Initialize n_pages_flushed in xtradb which was used uninitialized.

client/mysqltest.cc:
  Reduced memory usage (400K -> 80 for simple test;  400M -> 70M for some other tests)
  - Smaller dynamic arrays at start
  - Made 'st_connection' significantly smaller by allocation 'mysql' on demand in mysql_init() and storing require_file in a mem_root.
  - Fixed that when one does --debug we get information from safemalloc in the trace
  (Most of changes are changing &connect->mysql to connect->mysql
libmysql/libmysql.c:
  Don't call mysql_thread_end() if my_init() was called outside of mysql_server_init()
  This is needed to get information from my_end() into the DBUG log
mysql-test/README:
  Fixed wrong comment
mysql-test/mysql-test-run.pl:
  Reserv 20 ports / mysql-test-run thread.
  (Needed as some tests uses 9 mysqld servers)
mysys/hash.c:
  More DBUG information
mysys/my_bitmap.c:
  Fixed bug where bitmap_set_prefix() wrote over buffer area.
mysys/safemalloc.c:
  More DBUG information
mysys/thr_mutex.c:
  Initialize smaller arrays be default.
sql-common/client.c:
  More DBUG_PRINT
storage/xtradb/srv/srv0srv.c:
  Initialize n_pages_flushed which was used uninitialized.

This directory contains a test suite for the MySQL daemon. To run
the currently existing test cases, simply execute ./mysql-test-run in
this directory. It will fire up the newly built mysqld and test it.
Note that you do not have to have to do "make install", and you could
actually have a co-existing MySQL installation. The tests will not
conflict with it. To run the test suite in a source directory, you
must do make first.
All tests must pass. If one or more of them fail on your system, please
read the following manual section for instructions on how to report the
problem:
http://kb.askmonty.org/v/reporting-bugs
If you want to use an already running MySQL server for specific tests,
use the --extern option to mysql-test-run. Please note that in this mode,
the test suite expects you to provide the names of the tests to run.
For example, here is the command to run the "alias" and "analyze" tests
with an external server:
mysql-test-run --extern socket=/tmp/mysql.sock alias analyze
To match your setup, you might also need to provide --socket, --user, and
other relevant options.
With no test cases named on the command line, mysql-test-run falls back
to the normal "non-extern" behavior. The reason for this is that some
tests cannot run with an external server.
You can create your own test cases. To create a test case, create a new
file in the t subdirectory using a text editor. The file should have a .test
extension. For example:
xemacs t/test_case_name.test
In the file, put a set of SQL statements that create some tables,
load test data, and run some queries to manipulate it.
We would appreciate it if you name your test tables t1, t2, t3 ... (to not
conflict too much with existing tables).
Your test should begin by dropping the tables you are going to create and
end by dropping them again. This ensures that you can run the test over
and over again.
If you are using mysqltest commands (like result file names) in your
test case, you should create the result file as follows:
mysql-test-run --record test_case_name
or
mysqltest --record < t/test_case_name.test
If you only have a simple test cases consisting of SQL statements and
comments, you can create the test case in one of the following ways:
mysql-test-run --record test_case_name
mysql test < t/test_case_name.test > r/test_case_name.result
mysqltest --record --database test --result-file=r/test_case_name.result < t/test_case_name.test
When this is done, take a look at r/test_case_name.result
- If the result is incorrect, you have found a bug. In this case, you should
edit the test result to the correct results so that we can verify
that the bug is corrected in future releases.
If you want to submit your test case you can send it
to maria-developers@lists.launchpad.com or attach it to a bug report on
https://bugs.launchpad.net/maria/.
If the test case is really big or if it contains 'not public' data,
then put your .test file and .result file(s) into a tar.gz archive,
add a README that explains the problem, ftp the archive to
ftp://ftp.askmonty.org/private and send a mail to
https://bugs.launchpad.net/maria/ about it.
