Michael Widenius b95d2778aa Fixes bugs found by testcase for lp:815022 and lp:726374 "ma_blockrec.c:3000: write_block_record: Assertion `cur_block[1].page_count == 0' failed with a multi-index Aria workload"
The issues was:
- For some tables with a lot of not packed fields, we didn't allocate enough memory in head page which caused DBUG_ASSERT's
- Removed wrong DBUG_ASSERT()
- Fixed a problem with underflow() where it generates a key page where all keys didn't fit.
- Max key length is now limited by block_size/3  (was block_size /2).  This is required for underflow() to work with packed keys.




mysql-test/lib/v1/mysql-test-run.pl:
  Remove --alignment=8 as this doesn't work on 64 bit systems
mysql-test/suite/maria/r/small_blocksize.result:
  Test case for Aria bug
mysql-test/suite/maria/t/small_blocksize-master.opt:
  Test case for Aria bug
mysql-test/suite/maria/t/small_blocksize.test:
  Test case for Aria bug
storage/maria/ha_maria.cc:
  Fixed comment
storage/maria/ma_bitmap.c:
  Fixed wrong variable usage in find_where_to_split_row() where we allocated too little memory for head page.
  We did not take into account space for head extents (long VARCHAR) when trying to split row on head page. This caused us to allocate too little space from bitmap which lead to ASSERT failures later.
storage/maria/ma_blockrec.c:
  Made some argument const (to ensure they was not accidently changed)
  Removed wrong DBUG_ASSERT()
storage/maria/ma_blockrec.h:
  Removed not used variable
storage/maria/ma_delete.c:
  Added my_afree() in case of error
  More comments and DBUG_ASSERT() for underflow()
storage/maria/ma_open.c:
  Make keyinfo->underflow_block_length smaller for packed keys. This has to be done as for long packed keys, underflow() otherwise generates a key page where all keys didn't fit.
storage/maria/ma_page.c:
  New DBUG_ASSERT()
storage/maria/ma_write.c:
  Fixed comment
storage/maria/maria_def.h:
  We have to have space for at least 3 keys on a key page.
  (Otherwise the underflow() code doesn't work for packed keys, even when we have an underflow() for an empty key page)

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.
