The issue was that Aria allowed too long keys to be created (so that the internal buffer was not big enough to hold the whole key).
Key lengths is now limited to HA_MAX_KEY_LENGTH (1000), as for MyISAM.
Fixed failure in  "_ma_apply_redo_index: Assertion `new_page_length == 0", as found by buildbot.

mysql-test/suite/maria/r/maria.result:
  Updated results
mysql-test/suite/maria/r/maria3.result:
  Updated results. Added test for bug fix
mysql-test/suite/maria/t/maria3.test:
  Updated results. Added test for bug fix
mysql-test/suite/maria/t/optimize.test:
  Updated test for new max key length
storage/maria/ha_maria.cc:
  Limit key to HA_MAX_KEY_LENGTH.
storage/maria/ma_key_recover.c:
  Limit used page length to max page size (this is in line with the code that writes the entry to the log).
  This fixes failure in  "_ma_apply_redo_index: Assertion `new_page_length == 0", as found by buildbot.
storage/maria/ma_search.c:
  Extra DBUG
storage/maria/ma_write.c:
  Added test to detect errors earlier.

A better fix for this bug will be pulled from mariadb-5.2.

The field key_cache_mem_size of the KEY_CACHE structure must be
initialized in the function init_key_cache() and updated in the
function resize_key_cache().

Cause of the bug is uninitialized items before evaluation HAVING clasue in case of empty result.

The result of materialization of the right part of an IN subquery predicate
is placed into a temporary table. Each row of the materialized table is
distinct. A unique key over all fields of the temporary table is defined and
created. It allows to perform key look-ups into the table.
The table created for a materialized subquery can be accessed by key as
any other table. The function best_access-path search for the best access
to join a table to a given partial join. With some where conditions this
function considers a possibility of a ref_or_null access. If such access
employs the unique key on the temporary table then when estimating
the cost this access the function tries to use the array rec_per_key. Yet,
such array is not built for this unique key. This causes a crash of the server.

Rows returned by the subquery that contain nulls don't have to be placed
into temporary table, as they cannot be match any row produced by the
left part of the subquery predicate. So all fields of the temporary table
can be defined as non-nullable. In this case any ref_or_null access
to the temporary table does not make any sense and it does not make sense
to estimate such an access.

The fix makes sure that the temporary table for a materialized IN subquery
is defined with columns that are all non-nullable. The also ensures that 
any row with nulls returned by the subquery is not placed into the
temporary table.  

- Enable subquery materialization for CREATE TABLE ... SELECT.

Problem was a crash in internal temporary (Maria) files when row length exceeded 65535

mysql-test/suite/maria/r/maria3.result:
  Added test case
mysql-test/suite/maria/t/maria3.test:
  Added test case
storage/maria/ma_open.c:
  Added support for row length > 65535.
  This fixes crash when using tables with longer row lengths.

- After the exec_const_cond->val_int() call, check for error and return.
  (if we don't do it, we will eventually hit an error when trying to set status OK in 
   the diagnostics area, which already has an error status).

Removed const declarations to get rid of compiler warnings. The changes are similar to what is done in innobase in MySQL 5.5

BUILD/SETUP.sh:
  By default, build also with innodb-plugin
mysql-test/mysql-test-run.pl:
  Also search in lib64 directory for plugins (This is used at least on OpenSuse 12.1 when using default build scripts)
mysql-test/r/lock_multi.result:
  Allow test to be re-run even if it crashed.
mysql-test/t/lock_multi.test:
  Allow test to be re-run even if it crashed.
scripts/make_binary_distribution.sh:
  Ensure that libexecdir is named libexec (was not on OpenSuse 12.1)
scripts/mysql_config.sh:
  Fixed detection of lib64 was used.

This also fixes a (not likely) crashing bug when forcing a thread that was doing a table lock to re-open it's files, for example by creating a trigger.


mysys/thr_lock.c:
  Added more checking to find wrong locks.
  Removed one, not needed, parameter to thr_lock
sql/lock.cc:
  Fixed mysql_lock_tables() to retry with new sql_lock if lock fails. This was needed as table may be closed and reopened between retry's and then the old sql_lock will point to stale data.
sql/mysql_priv.h:
  Updated prototype
sql/sql_base.cc:
  Ensure that all tables are closed if opening of system table failes; This fixes the assert in THD::restore_backup_open_tables_state
sql/sql_handler.cc:
  Updated variable type

 execution which mtr --embedded does not support

Sort counters by their names (otherwise, the order of SHOW STATUS output is sometimes sorted and sometimes not)

 Handler_mrr_key_refills, Handler_mrr_rowid_refills.

the mysql-5.6 code line.

UNIX_TIMESTAMP() can be null, and returns null for invalid values

Fixed compiler warnings found by buildbot

Makefile.am:
  Removed extra empty line
cmd-line-utils/libedit/sys.h:
  Fixed that strndup() doesn't give compiler warnings
mysql-test/Makefile.am:
  Fixes for 'make distcheck'
plugin/auth_pam/auth_pam.c:
  Ensure that prototype for strndup() is included on linux
sql/share/Makefile.am:
  Fixes for 'make distcheck'
storage/innodb_plugin/btr/btr0sea.c:
  Fixed compiler warning
support-files/Makefile.am:
  Fixes for 'make distcheck'

mysql-test/suite/innodb_plugin/t/innodb_gis.test:
  Don't run test if innodb_plugin isn't used.

sql/signal_handler.cc:
  Added missing signal values.

Fixed supression in mysql-test-run so it also works on windows.

mysql-test/mysql-test-run.pl:
  Fixed supression so it also works on windows.
mysql-test/valgrind.supp:
  More general handling of memory loss in dlclose (backported from 5.2)
sql/signal_handler.cc:
  Added newlines around link to how to do bug reports

"relocation R_X86_64_PC32 against `handler_index_cond_check' can not be used when making a shared object; recompile with -fPIC"
