myisam/mi_uniue.c:mi_check_unique() should skip trailing spaces comparing 
TEXT and VARTTEXT key segments.


myisam/mi_unique.c:
  Fix for bug #20709: Collation not used in group by on 4.1.    
  
  myisam/mi_uniue.c:mi_check_unique() should skip trailing spaces comparing 
  TEXT and VARTTEXT key segments.
    
  Example: assume, we have a 'char(200) collate utf8_unicode_ci' field,
  there are two records with _utf8"0x65" and _utf8"0xC3A9" characters;
  these values are equal according
  to the utf8_unicode_ci collation, but two 600 byte length corresponding keys:  
  "0x65<0x20 repeats 599 times>" and "0xC3A9<0x20 repeats 598 times>" are not    
  equal if we count trailing spaces and it may cause inconsequent behavior.
  
  So, let's pass 1 as the skip_end_space parameter value to the mi_compare_text()
  function for proper TEXT and VARTTEXT key segments comparison.

Problem described in this bug report affects MyISAM tables only.

Running mysqld --flush instructs mysqld to sync all changes to disk
after each SQL statement. It worked well for INSERT and DELETE
statements, but it did sync for UPDATE only in case if there was
index change (change of colum that has an index). If no updated column
has an index, data wasn't synced to disk.

This fix makes UPDATE statement to sync data to disk even if there is
no index change (that is only data change) and mysqld is run with
--flush option.


myisam/mi_update.c:
  Every myisam function that updates myisam table must end with
  call to _mi_writeinfo(). If operation (second param of
  _mi_writeinfo()) is not 0 it sets share->changed to 1, that is
  flags that data has changed. If operation is 0, this function
  equals to no-op in this case.
  
  mi_update() must always pass !0 value as operation, since even if
  there is no index change there could be data change.

This problem is 4.1 specific. It doesn't affect 4.0 and was fixed
in 5.x before.

Having any mysql user who is allowed to issue multi table update
statement and any column/table grants, allows this user to update
any table on a server (mysql grant tables are not exception).

check_grant() accepts number of tables (in table list) to be checked
in 5-th param. While checking grants for multi table update, number
of tables must be 1. It must never be 0 (actually we have
DBUG_ASSERT(number > 0) in 5.x in grant_check() function).

When processing aggregate functions all tables values are reset
to NULLs at the end of each group. 
When doing that if there are no rows found for a group
the const tables must not be reset as they are not recalculated 
by do_select()/sub_select() for each group.


mysql-test/r/subselect2.result:
  * Bug #20792: Incorrect results from aggregate subquery
   - test suite for the bug. This is dependent on InnoDB despite
     the fact that the bug and the fix are not InnoDB specific.
     This is because of the table flag HA_NOT_EXACT_COUNT.
     When this flag is off (as in MyISAM) both t2 and t3 become of
     join type 'system' as they are estimated to have 1 record and
     and this statistics can be trusted (according to the absence of
     HA_NOT_EXACT_COUNT).

Too many cursors (more than 1024) could lead to memory corruption.
This affects both, stored routines and C API cursors, and the
threshold is per-server, not per-connection.  Similarly, the
corruption could happen when the server was under heavy load
(executing more than 1024 simultaneous complex queries), and this is
the reason why this bug is fixed in 4.1, which doesn't support
cursors.

The corruption was caused by a bug in the temporary tables code, when
an attempt to create a table could lead to a write beyond allocated
space.  Note, that only internal tables were affected (the tables
created internally by the server to resolve the query), not tables
created with CREATE TEMPORARY TABLE.  Another pre-condition for the
bug is TRUE value of --temp-pool startup option, which, however, is a
default.

The cause of a bug was that random memory was overwritten in
bitmap_set_next() due to out-of-bound memory access.


mysys/my_bitmap.c:
  Local 'bitmap_size' is measured in bytes, no need to multiply it by 8.
sql/sql_select.cc:
  Clear the temp_pool_slot bit only if we have set it previously.

 When optimizing conditions like 'a = <some_val> OR a IS NULL' so that they're
 united into a single condition on the key and checked together the server must 
 check which value is the NULL value in a correct way : not only using ->is_null 
 but also check if the expression doesn't depend on any tables referenced in the 
 current statement. 
 This additional check must be performed because that optimization takes place 
 before the actual execution of the statement, so if the field was initialized 
 to NULL from a previous statement the optimization would be applied incorrectly.

  Send the ouput from "mysqlbinlog" to a file and then read execute it with "mysql"
  This is a workaround for a windows bug in the test tools in mysql-4.1, which makes
  it impossible to use "|" to send the output from one program directly to the other.
  This has been fixed in mysql-5.0.
