Subject: [PATCH 04/20] Fixed bug#14169: type of group_concat() result changed
 to blob if tmp_table was used

In a simple queries a result of the GROUP_CONCAT() function was always of
varchar type.
But if length of GROUP_CONCAT() result is greater than 512 chars and temporary
table is used during select then the result is converted to blob, due to
policy to not to store fields longer than 512 chars in tmp table as varchar
fields.

In order to provide consistent behaviour, result of GROUP_CONCAT() now
will always be converted to blob if it is longer than 512 chars.
Item_func_group_concat::field_type() is modified accordingly.

  Added test case for bug#14169: type of group_concat() result changed to blob if tmp_table was used
mysql-test/r/func_gconcat.result:
  Added test case for bug#14169: type of group_concat() result changed to blob if tmp_table was used

sql/sql_select.cc:
  Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was used
  The unnamed constant 255 in the create_tmp_field() and create_tmp_field_from_item() functions now defined as the CONVERT_IF_BIGGER_TO_BLOB constant.
  The create_tmp_field() function now converts the Item_sum string result to a blob field based on its char length.
sql/item_sum.h:
  Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was used
  To the Item_func_group_concat calls added the member function field_type() which returns the BLOB or VAR_STRING type based on the items length.
sql/item_func.cc:
  Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was used
  In the Item_func::tmp_table_field() function the unnamed constant 255 is changed to the CONVERT_IF_BIGGER_TO_BLOB constant.
  The Item_func::tmp_table_field() function now measures the result length in chars rather than bytes when converting string result to a blob.

Subject: [PATCH 05/20] Bug#18691: Converting number to UNICODE string returns
 invalid result.

Conversion from int and real numbers to UCS2 didn't work fine:
CONVERT(100, CHAR(50) UNICODE)
CONVERT(103.9, CHAR(50) UNICODE)

The problem appeared because numbers have binary charset, so,
simple charset recast binary->ucs2 was performed
instead of real conversion.

Fixed to make numbers pretend to be non-binary.

Subject: [PATCH 06/20] BUG#17917 - SELECT from compressed MyISAM table crashes
 MySQL server

Retrieving data from compressed MyISAM table which is bigger than 4G on 32-bit box
with mmap() support results in server crash.

mmap() accepts length of bytes to be mapped in second param, which is 32-bit
size_t. But we pass data_file_length, which is 64-bit my_off_t. As a result only
first data_file_length % 4G were mapped.

This fix adds additional condition for mmap() usage, that is use mmap() for
compressed table which size is no more than 4G on 32-bit platform.


myisam/mi_packrec.c:
  Use mmap() for compressed table which size is no more than 4G on 32-bit platform.

Subject: [PATCH 09/20] Fixes for Bug#12429: Replication tests fail:
 "Slave_IO_Running" (?) differs related to MySQL 4.1   and Bug#16920
 rpl_deadlock_innodb fails in show slave status (reported for MySQL 5.1)   -
 backport of several fixes done in MySQL 5.0 to 4.1   - fix for new discovered
 instability (see comment on Bug#12429 + Bug#16920)   - reenabling of
 testcases

mysql-test/r/rpl_deadlock.result:
  Updated results
mysql-test/r/rpl_relayrotate.result:
  Updated results
mysql-test/t/disabled.def:
  Reenabling of tests
mysql-test/t/rpl_deadlock.test:
  - replace sleep with real_sleep (backport fix for Bug#15624 MySQL 5.0)
  - egalized value for Slave_IO_Running
  - line 105 (backport fix for Bug#12429 MySQL 5.0)
  - line 85 (see comment in Bug#12429
             + Bug#16920 rpl_deadlock_innodb fails in show slave status)
  - improve readability of show slave status output (--vertical_results)
mysql-test/t/rpl_relayrotate.test:
  - Replace select ... with select max(a)
  - add sync_with_master (backport fix done by Kristian in MySQL 5.0 because of timing
    problems similar to Bug#15624)
mysql-test/t/rpl_until.test:
  Add wait_for_slave_to_stop like in the current MySQL 5.0 version of this test.
  I assume this makes the test results more predictable.

Subject: [PATCH 10/20] Fixed bug #19079. The bug caused a reported index
 corruption in the cases when key_cache_block_size was not a multiple of
 myisam_block_size, e.g. when key_cache_block_size=1536 while
 myisam_block_size=1024.

mysql-test/r/key_cache.result:
  Added a test case for bug #19079.
mysql-test/t/key_cache.test:
  Added a test case for bug #19079.

Subject: [PATCH 11/20] Bug#18544 - LOCK TABLES timeout causes MyISAM table
 corruption

After a locking error the open table(s) were not fully
cleaned up for reuse. But they were put into the open table
cache even before the lock was tried. The next statement
reused the table(s) with a wrong lock type set up. This
tricked MyISAM into believing that it don't need to update
the table statistics. Hence CHECK TABLE reported a mismatch
of record count and table size.

Fortunately nothing worse has been detected yet. The effect
of the test case was that the insert worked on a read locked
table. (!)

I added a new function that clears the lock type from all
tables that were prepared for a lock. I call this function
when a lock failes.

No test case. One test would add 50 seconds to the
test suite. Another test requires file mode modifications.
I added a test script to the bug report. It contains three
cases for failing locks. All could reproduce a table
corruption. All are fixed by this patch.

This bug was not lock timeout specific.


sql/lock.cc:
  Bug#18544 - LOCK TABLES timeout causes MyISAM table corruption
  Resetting the lock type in the open table(s) lock data
  after a locking error.

+    reset_lock_data()
+      sql_lock                  The MySQL lock.
+
+  DESCRIPTION
+
+    After a locking error we want to quit the locking of the table(s).
+    The test case in the bug report for Bug #18544 has the following
+    cases: 1. Locking error in lock_external() due to InnoDB timeout.
+    2. Locking error in get_lock_data() due to missing write permission.
+    3. Locking error in wait_if_global_read_lock() due to lock conflict.
+
+    In all these cases we have already set the lock type into the lock
+    data of the open table(s). If the table(s) are in the open table
+    cache, they could be reused with the non-zero lock type set. This
+    could lead to ignoring a different lock type with the next lock.
+
+    Clear the lock type of all lock data. This ensures that the next
+    lock request will set its lock type properly.
+
+  RETURN

Subject: [PATCH 16/20] Fixed bug #18767. The bug caused wrong result sets for
 union constructs of the form (SELECT ... ORDER BY order_list1 [LIMIT n])
 ORDER BY order_list2. For such queries order lists were concatenated and
 limit clause was completely neglected.

mysql-test/r/order_by.result:
  Added a test case for bug #18767.
mysql-test/t/order_by.test:
  Added a test case for bug #18767.
sql/sql_lex.h:
  Fixed bug #18767.
  Placed the code the created a fake SELECT_LEX into a separate function.
sql/sql_parse.cc:
  Fixed bug #18767.
  Placed the code the created a fake SELECT_LEX into a separate function.
sql/sql_select.cc:
  Fixed bug #18767.
  Changed the condition on which a SELECT is treated as part of a UNION.
  The SELECT in
  (SELECT ... ORDER BY order_list1 [LIMIT n]) ORDER BY order_list2
  now is handled in the same way as the first SELECT in a UNION
  sequence.
sql/sql_union.cc:
  Fixed bug #18767.
  Changed the condition at which a SELECT is treated as part of a UNION.
  The SELECT in
  (SELECT ... ORDER BY order_list1 [LIMIT n]) ORDER BY order_list2
  now is handled in the same way as the first SELECT in a UNION
  sequence.
sql/sql_yacc.yy:
  Fixed bug #18767.
  Changed the condition at which a SELECT is treated as part of a UNION.
  The SELECT in
  (SELECT ... ORDER BY order_list1 [LIMIT n]) ORDER BY order_list2
  now is handled in the same way as the first SELECT in a UNION
  sequence. In the same way is handled the SELECT in
  (SELECT ... LIMIT n) ORDER BY order list.
  Yet if there is neither ORDER BY nor LIMIT in the single-select
  union construct
  (SELECT ...) ORDER BY order_list
  then it is still handled as simple select with an order clause.

Subject: [PATCH 18/20] Bug#17263 temporary tables and replication  
 Backporting a changeset made for 5.0. Comments from there:

  The fix refines the algorithm of generating DROPs for binlog.
  Temp tables with common pseudo_thread_id are clustered into one query.
  Consequently one replication event per pseudo_thread_id is generated.




mysql-test/r/rpl_temporary.result:
  results changed
mysql-test/t/rpl_temporary.test:
  test to generate problematic drop in binlog to feed it to restarting slave
  to see no stop.
sql/sql_base.cc:
  change in drop temprorary tables alg in close_temporary_tables.

Subject: [PATCH 19/20] Bug#17263: incorrect DROP query in temporary tables
 replication accounting non-ai32 in tmpkeyval. This changeset is supposed to
 be specifically for 4.1. Another changeset is going to push into 5.

sql/sql_base.cc:
  correction due to uint4korr definition: can not sizeof on not ia32.
