Guilhem Bichot a955efc40c Fix for BUG#41493 "Maria: two recovery failures (wrong logging of BLOB pages)" and some more debugging
output related to this.

mysql-test/suite/maria/r/maria-recovery3.result:
  result update
mysql-test/suite/maria/t/maria-recovery3.test:
  Test for bug; before the fix, the "CHECK TABLE EXTENDED" would mention a bad bitmap, because the
  REDO_INSERT_ROW_BLOBS was containing a page number which was actually the one of a tail, so execution of this
  record would mark the tail page as full in bitmap (like if it were a blob page), though it wasn't full.
  Also, the assertion added around ma_blockrec.c:6580 in the present revision fired.
storage/maria/ma_blockrec.c:
  - fix for BUG#41493: if we found out that logging was not needed at this point (blob_length==0 i.e. tail page),
  then we forgot to increment tmp_block, so in the second iteration (assuming two BLOB columns), we would log the
  page range of the first iteration (i.e. the tail page's number) for this second BLOB, which would cause
  Recovery to overwrite the tail page with the second BLOB.
  - assert when marking the table corrupted during REDO phase; this catches some problems earlier
  otherwise they get caught only when a later record wants to use the table.
  - _ma_apply_redo_insert_row_blobs() now fills some synthetic info about the blobs and pages involved
  in a REDO_INSERT_ROW_BLOBS record, for inclusion into maria_recovery.trace: number of blobs, of ranges,
  first and last page (does not tell about any gaps in the middle, but good enough for now). It also asserts
  that it's not overwriting a tail/head page (which happened in the bug).
storage/maria/ma_blockrec.h:
  new prototype for _ma_apply_redo_insert_row_blobs
storage/maria/ma_recovery.c:
  Print info got from _ma_apply_redo_insert_row_blobs() to maria_recovery.trace (so far this file had mentioned
  what head and tail pages a record touched, but not blob pages).

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.

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://dev.mysql.com/doc/mysql/en/mysql-test-suite.html

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 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 --record-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.

To submit your test case, 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://support.mysql.com/pub/mysql/secret/ and send a mail
to bugs@lists.mysql.com
