Subject: [PATCH 01/11] Bug#27580 SPACE() function collation bug? Problem: when
 character_set_connection=utf8, mixing SPACE() with a non-Unicode column (e.g.
 for concat) produced "illegal mix of collations" error. Fix: Item_string()
 corresponding to space character is now created using "ASCII" repertoire.
 Previously it was incorrectly created using "UNICODE" repertoure, which
 didn't allow to convert results of SPACE() to a non-Unicode character set.

mysql-test/include/ctype_common.inc:
  - Adding test for bug#27580
  - Restoring previous values of character_set_client and character_set_results,
  because ctype_common.inc now changes them when doing "set names utf8"
  in the test for bug#27580

  to allow automatic conversion from UTF8 to column's character
  set e.g. for CONCAT().

Subject: [PATCH 02/11] Bug#32705 - myisam corruption: Key in wrong position   
          at page 1024 with ucs2_bin

Inserting strings with a common prefix into a table with
characterset UCS2 corrupted the table.

An efficient search method was used, which compares end space
with ASCII blank. This doesn't work for character sets like UCS2,
which do not encode blank like ASCII does.

Use the less efficient search method _mi_seq_search()
for charsets with mbminlen > 1.


myisam/mi_open.c:

Subject: [PATCH 05/11] Fix for bug #33758: Got query result when using ORDER
 BY ASC, but empty result when using DESC

Problem: fetching MyISAM keys we copy a key block pointer to the end of the key buffer.
However, we don't take into account the pointer length calculatig the buffer size,
that may leads to memory overwriting and in turn to unpredictable results.

Fix: increase key buffer size by length of the key block pointer.

Note: no simple test case.


myisam/mi_open.c:
  Fix for bug #33758: Got query result when using ORDER BY ASC, but
  empty result when using DESC
    - increase possible maximum key length by size of the key block pointer,
      as it's copied into the key buffer in the get_key() MyISAM functions.

 gives error 1430             from storage engine

Federated may crash a server, return wrong result set, return
"ERROR 1030 (HY000): Got error 1430 from storage engine" message
when local (engine=federated) table has a key against nullable
column.

The problem was wrong implementation of function that creates
WHERE clause for remote query from key.


mysql-test/r/federated.result:
  A test case for BUG#33946.
mysql-test/t/federated.test:
  A test case for BUG#33946.
sql/ha_federated.cc:
  Fixed that federated adds " IS NULL " condition to a remote query,
  whereas "IS NOT NULL" requested by original query.

  Fixed that federated didn't check for end of key buffer, didn't
  setup key buffer pointer and remaining lenght of key buffer,
  didn't add " AND " between conditions in case original query
  has IS [NOT] NULL condition against nullable column.

  Fixed that federated wrongly shifts key buffer pointer by extra
  one byte when key part may be null (was: store_length + 1,
  now: store_length).

Subject: [PATCH 07/11] Fix for bug #33304: Test 'func_group' hangs on Mac OS X
 10.4 PowerPC 64-bit

Problem: SLEEP(0) never returns on 64-bit Mac OS X due to a bug in
pthread_cond_timedwait().

Fix: when given a very short timeout just return immediately.


sql/item_func.cc:
  Fix for bug #33304: Test 'func_group' hangs on Mac OS X 10.4 PowerPC 64-bit

  - if given a very short timeout (< 10 mcs) just return from SLEEP().

With this fix NAME_CONST() inherits collation from the value argument.

Subject: [PATCH 09/11] BUG#13861 - START SLAVE UNTIL may stop 1 evnt too late
 if             log-slave-updates and circul repl

Slave SQL thread may execute one extra event when there are events
skipped by slave I/O thread (e.g. originated by the same server).
Whereas it was requested not to do so by the UNTIL condition.

This happens because we compare with the end position of previously
executed event. This is fine when there are no skipped by slave I/O
thread events, as end position of previous event equals to start
position of to be executed event. Otherwise this position equals to
start position of skipped event.

This is fixed by:
- reading the event to be executed before checking if the until condition
  is satisfied.
- comparing the start position of the event to be executed. Since we do
  not have the start position available, we compute it by subtracting
  event length from end position (which is available).
- if there are no events on the event queue at the slave sql starting
  time, that meet until condition, we stop immediately, as in this
  case we do not want to wait for next event.

  Store length of event. This is needed for further calculation of

  Slave SQL thread may execute one extra event when there are events
  skipped by slave I/O thread (e.g. originated by the same server).
  Whereas it was requested not to do so by the UNTIL condition.

Subject: [PATCH 10/11] Bug#23097 mysql can't insert korean on mysql prompt.
 Problem: libedit is a very pure-ASCII oriented library, and it is not aware
 of extended (0x80..0xFF) or even multi-byte characters. It considered such
 characters as non-printable and didn't allow to input them. Fix: make libedit
 think that all bytes >= 0x80 are printable.

cmd-line-utils/libedit/el.h:
  Defining macro, a locale's isprint() replacement.
  We'll consider all 8bit values as printable characters.
