6ac3d502d7 Bug#32091: Security breach via directory changes
Problem: the table's INDEX and DATA DIR was taken
  directly from the table's first partition.
  This allowed rename attack similar to
  bug#32111 when ALTER TABLE REMOVE PARTITIONING

Solution: Silently ignore the INDEX/DATA DIR
  for the table. (Like some other storage engines
  do). 
  Partitioned tables do not support DATA/INDEX
  DIR on the table level, only on its partitions.

55499d2bf4 Fix for bug #32202: ORDER BY not working with GROUP BY
The bug is a regression introduced by the fix for bug30596. The problem
was that in cases when groups in GROUP BY correspond to only one row,
and there is ORDER BY, the GROUP BY was removed and the ORDER BY
rewritten to ORDER BY <group_by_columns> without checking if the
columns in GROUP BY and ORDER BY are compatible. This led to
incorrect ordering of the result set as it was sorted using the
GROUP BY columns. Additionaly, the code discarded ASC/DESC modifiers
from ORDER BY even if its columns were compatible with the GROUP BY
ones.

This patch fixes the regression by checking if ORDER BY columns form a
prefix of the GROUP BY ones, and rewriting ORDER BY only in that case,
preserving the ASC/DESC modifiers. That check is sufficient, since the
GROUP BY columns contain a unique index.

737cdfeaeb Fix for bug #32020: loading udfs while --skip-grant-tables is enabled
causes out of memory errors

The code in mysql_create_function() and mysql_drop_function() assumed
that the only reason for UDFs being uninitialized at that point is an
out-of-memory error during initialization. However, another possible 
reason for that is the --skip-grant-tables option in which case UDF 
initialization is skipped and UDFs are unavailable.

The solution is to check whether mysqld is running with
--skip-grant-tables and issue a proper error in such a case.

0347bfcd5f Remove the --source-install option and instead make use of --srcdir
to install system tables directly from the source tree (useful for
testing purposes).  This helps clean the script up a lot and clarify
the three possible ways the script can be called (using compiled-in
paths, passing --basedir pointing to alternative install location,
or --srcdir).  Include further tidying as well.
  
This fixes bug#30759.

  Re-order the logic in printing messages at the end of the
  script, to make it clearer which paths are taken depending
  on tests or outcome of command status.  Tidy some output.

b1fc4b9e63 Bug#31990: MINUTE() and SECOND() return bogus results when used on a DATE
HOUR(), MINUTE(), ... returned spurious results when used on a DATE-cast.
This happened because DATE-cast object did not overload get_time() method
in superclass Item. The default method was inappropriate here and
misinterpreted the data.

Patch adds missing method; get_time() on DATE-casts now returns SQL-NULL
on NULL input, 0 otherwise. This coincides with the way DATE-columns
behave.

707f42a6b9 Bug #20748: Configuration files should not be read more than once
A user could not override system-wide settings in their ~/.my.cnf,
because the DEFAULT_SYSCONFDIR was being searched last.  Also, in
some configurations (especially when the --sysconfdir compile-time
option is set to /etc or /etc/mysql), the system-wide my.cnf file
was read multiple times, causing confusion and potential problems.

Rearrange default directories to conform to the manual and logic.
Move --sysconfdir=<path> (DEFAULT_SYSCONFDIR) from the last default
directory to the middle of the list.  $HOME/.my.cnf should be last,
so the user is able to override the system-wide settings.

Change init_default_directories() to remove duplicates from the
list.

mysys/default.c:
  Change order in which defaults files are added to default_directories,
  in order to conform to the manual (and to common sense).  This fixes
  a particularly bad problem on Unix, where ~/.my.cnf was read before
  /usr/local/etc/my.cnf.
  
  Also, don't add duplicate entries; move the existing entry to the
  end of the list instead.
  
  
  Here is a comparison of the order of defaults files, BEFORE and AFTER
  this patch.
  
  On Windows:
  
  BEFORE:  C:\, GetWindowsDirectory(), GetSystemWindowsDirectory(),
           $MYSQL_HOME, defaults-extra-file, INSTALLDIR
  
  AFTER:  GetSystemWindowsDirectory(), GetWindowsDirectory(), C:\,
          INSTALLDIR, $MYSQL_HOME, defaults-extra-file
  
  GetSystemWindowsDirectory() is moved before GetWindowsDirectory() because
  the former is shared by all Terminal Services users, while the latter is
  private for each user.
  
  
  On Netware (no change):
  
  BEFORE:  sys:/etc/, $MYSQL_HOME, defaults-extra-file
  
  AFTER:  sys:/etc, $MYSQL_HOME, defaults-extra-file
  
  
  On OS/2:
  
  BEFORE:  $ETC, /etc, $MYSQL_HOME, defaults-extra-file
  
  AFTER:  /etc, $ETC, $MYSQL_HOME, defaults-extra-file
  
  
  On everything else (general Unix):
  
  BEFORE:  /etc, $MYSQL_HOME, defaults-extra-file, ~/, --sysconfdir
  
  AFTER:  /etc/, --sysconfdir, $MYSQL_HOME, defaults-extra-file, ~/
  
  The BEFORE code added --sysconfdir on all systems, but only the
  Unix build system actually defined a value for it.

0a7a55d175 Fix for bug #32103: optimizer crash when join on int and mediumint with
variable in where clause.

Problem: the new_item() method of Item_uint used an incorrect
constructor. "new Item_uint(name, max_length)" calls
Item_uint::Item_uint(const char *str_arg, uint length) which assumes the
first argument to be the string representation of the value, not the
item's name. This could result in either a server crash or incorrect
results depending on usage scenarios.

Fixed by using the correct constructor in new_item():
Item_uint::Item_uint(const char *str_arg, longlong i, uint length).

f668665955 Fix for bug #30666: Incorrect order when using range conditions on 2
tables or more

The problem was that the optimizer used the join buffer in cases when
the result set is ordered by filesort. This resulted in the ORDER BY
clause being ignored, and the records being returned in the order
determined by the order of matching records in the last table in join.

Fixed by relaxing the condition in make_join_readinfo() to take
filesort-ordered result sets into account, not only index-ordered ones.

  Fix for Bug# 31860, in the Bug 16979 fix there was an erroneous assertion that
  autoincrement columns can't contain negative values. With the fix, the
  autoincrement table counter is set to 0 if the maximum value read from
  the autoinc column index is negative.

Fixes the following bugs:

Bug #30706: SQL thread on slave is allowed to block client queries when slave load is high
  Add (innodb|innobase|srv)_replication_delay MySQL config parameter.

Bug #30888: Innodb table + stored procedure + row deletion = server crash
  While adding code for the low level read of the AUTOINC value from the index,
  the case for MEDIUM ints which are 3 bytes was missed triggering an
  assertion.

Bug #30907: Regression: "--innodb_autoinc_lock_mode=0" (off) not same as older releases
  We don't rely on *first_value to be 0 when checking whether
  get_auto_increment() has been invoked for the first time in a multi-row
  INSERT. We instead use trx_t::n_autoinc_rows. Initialize trx::n_autoinc_rows
  inside ha_innobase::start_stmt() too.

Bug #31444: "InnoDB: Error: MySQL is freeing a thd" in innodb_mysql.test
  ha_innobase::external_lock(): Update prebuilt->mysql_has_locked and
  trx->n_mysql_tables_in_use only after row_lock_table_for_mysql() returns
  DB_SUCCESS.  A timeout on LOCK TABLES would lead to an inconsistent state,
  which would cause trx_free() to print a warning.

Bug #31494: innodb + 5.1 + read committed crash, assertion
  Set an error code when a deadlock occurs in semi-consistent read.

  Fixed bug#28404.
  This patch adds cost estimation for the queries with ORDER BY / GROUP BY
  and LIMIT.
  If there was a ref/range access to the table whose rows were required
  to be ordered in the result set the optimizer always employed this access
  though a scan by a different index that was compatible with the required
  order could be cheaper to produce the first L rows of the result set.
  Now for such queries the optimizer makes a choice between the cheapest
  ref/range accesses not compatible with the given order and index scans
  compatible with it.

  Revision r1873:
  snprintf() should always return non-negative result. According to
  Microsoft documentation about _vscprintf():
  
    If format is a null pointer, the invalid parameter handler is invoked,
    as described in Parameter Validation. If execution is allowed to
    continue, the functions return -1 and set errno to EINVAL.
  
  The UNIX variant of snprintf() segfaults if format is a NULL pointer
  (similar to strlen(NULL) for example), so it is better to conform to
  this behavior and crash our custom Windows version instead of
  returning -1. Noone would expect -1 to be returned from snprintf().

  Add ut_snprintf() function. On Windows this needs to be implemented
  using auxiliary functions because there is no snprintf-variant on
  Windows that behaves exactly as specified in the standard:
  
  * Always return the number of characters that would have been printed
    if the size were unlimited (not including the final `\0').
  * Always '\0'-terminate the result
  * Do not touch the buffer if size=0, only return the number of characters
    that would have been printed. Can be used to estimate the size needed
    and to allocate it dynamically.
  
  See http://www.freebsd.org/cgi/query-pr.cgi?pr=87260 for the reason why
  2 ap variables are used.

  Revision r1866:
  Revert r1850 as MySQL did not approve the addition.
  
  log for r1850:
  
  Implement this feature request:
  http://bugs.mysql.com/30706
  
  * Add a function that returns the number of microseconds since
    epoch - ut_time_us().
  
  * Add (innodb|innobase|srv)_replication_delay MySQL config parameter.
  
  * Add UT_WAIT_FOR() macro that waits for a specified condition to occur
    until a timeout elapses.
  
  * Using all of the above, handle the replication thread specially in
    srv_conc_enter_innodb().
  
  
  Revision r1787:
  Move the prototype of innobase_print_identifier() from ut0ut.c to
  ha_prototypes.h.  Enclose the definitions in ha_prototypes.h in
  #ifndef UNIV_HOTBACKUP.
  
  
  Revision r1789:
  ut_print_namel(): Do not assume that all '/' are separators between
  database and table names.
  
  Approved by Heikki.
  
  
  Revision r1936:
  ut_print_buf(): Add a Valgrind check that the buffer is wholly defined.

  innodb-semi-consistent: New tests for InnoDB semi-consistent reads.
  Unfortunately, these will not trigger Bug #31494, because there merely
  occur lock wait timeouts, not deadlocks.
