batch_readline_init() was modified - make check for 
type of file for input stream unless target platform
is WINDOWS since on this platform S_IFBLK is undefined.

Reverse DNS lookup of "localhost" returns "broadcasthost" on Snow Leopard (Mac), and NULL on most others.
Simply ignore the output, as this is not an essential part of UDF testing.

batch_readline_init() was modified - return an error
if the input source is a directory or a block device.

This follow-up is necessary because on some platforms,
such as Solaris, call to read() from directory may be
successful.

Test failed on a certain Linux platform in automated environment. It turns out that this platform has an old version of Perl modules DBI and DBD::mysql installed, as well as the OS itself being relatively old.
Allowing error code 11 to be returned from mysqlhotcopy on expected error seems harmless and will make the test pass also with older libraries.

privileges".

The first problem was that DROP USER didn't properly remove privileges 
on stored functions from in-memory structures. So the dropped user
could have called stored functions on which he had privileges before
being dropped while his connection was still around.
Even worse if a new user with the same name was created he would
inherit privileges on stored functions from the dropped user.
Similar thing happened with old user name and function privileges
during RENAME USER.

This problem stemmed from the fact that the handle_grant_data() function
which handled DROP/RENAME USER didn't take any measures to update
in-memory hash with information about function privileges after
updating them on disk.

This patch solves this problem by adding code doing just that.

The second problem was that RENAME USER didn't properly update in-memory
structures describing table-level privileges and privileges on stored 
procedures. As result such privileges could have been lost after a rename
(i.e. not associated with the new name of user) and inherited by a new
user with the same name as the old name of the original user.

This problem was caused by code handling RENAME USER in
handle_grant_struct() which [sic!]:
a) tried to update wrong (tables) hash when updating stored procedure
   privileges for new user name.
b) passed wrong arguments to function performing the hash update and
   didn't take into account the way in which such update could have
   changed the order of the hash elements.

This patch solves this problem by ensuring that a) the correct hash
is updated, b) correct arguments are used for the hash_update()
function and c) we take into account possible changes in the order
of hash elements.

sql/sql_acl.cc:
  Changed handle_grant_data() to also update hash with function 
  privileges. This allows DROP/RENAME USER correctly keep this 
  in-memory structure up-to-date.
  
  To do this extended handle_grant_struct() to support updating of this
  hash. In addition fixed code in this function which is responsible for 
  handling of column and routine hashes during RENAME USER, ensured that
  we correctly update these hashes after changing user name and that we
  don't skip elements while iterating through the hash and doing updates.

      
Also fix bug#59110: Memory leak of QUICK_SELECT_I allocated memory.
Includes Jørgen Lølands review comments.
      
Root cause of these bugs are that test_if_skip_sort_order() decided to
revert the 'skip_sort_order' descision (and use filesort) after the
query plan has been updated to reflect a 'skip' of the sort order.
      
This might happen in 'check_reverse_order:' if we have a 
select->quick which could not be made descending by appending 
a QUICK_SELECT_DESC. ().
      
The original 'save_quick' was then restored after the QEP has been modified,
which caused:
      
  - An incorrect 'precomputed_group_by= TRUE' may have been set, 
    and not reverted, as part of the already modifified QEP (Bug#59308)
  - A 'select->quick' might have been created which we fail to delete (bug#59110).
      
This fix is a refactorication of test_if_skip_sort_order() where all logic
related to modification of QEP (controlled by argument 'bool no_changes'), is
moved to the end of test_if_skip_sort_order(), and done after *all* 'test_if_skip'
checks has been performed - including the 'check_reverse_order:' checks.
      
The refactorication above contains now intentional changes to the logic which 
has been moved to the end of the function.
      
Furthermore, a smaller part of the fix address the handling of the 
select->quick objects which may already exists when we call 
'test_if_skip_sort_order()' (save_quick) -and
new select->quick's created during test_if_skip_sort_order():
      
  - Before new select->quick may be created by calling ::test_quick_select(), we
    set 'select->quick= 0' to avoid that ::test_quick_select() prematurely
    delete the save_quick's. (After this call we may have both a 'save_quick' 
    and 'select->quick')
      
  - All returns from ::test_if_skip_sort_order() where we may have both a
    'save_quick' and a 'select->quick' has been changed to goto's to the
    exit points 'skiped_sort_order:' or 'need_filesort:' where we
    decide which of the QUICK_SELECT's to keep, and delete the other.

if the standard input is a directory.

The problem is that mysql monitor try to read from stdin without
checking input source type.

The solution is to stop reading data from standard input if a call
to read(2) failed.

A new test case was added into mysql.test.

client/my_readline.h:
  Data members error and truncated was added to LINE_BUFFER structure.
  These data members used instead of out parameters in functions
  batch_readline, intern_read_line.
client/mysql.cc:
  read_and_execute() was modified: set status.exit_status to 1
  when the error occured while reading the next command line in
  non-interactive mode. Also the value of the truncated attribute
  of structure LINE_BUFF is taken into account only for non-iteractive mode.
client/readline.cc:
  intern_read_line() was modified: cancel reading from input if
  fill_buffer() returns -1, e.g. if call to read failed.
  batch_readline was modified: set the error data member of LINE_BUFFER
  structure to value of my_errno when system error happened during call
  to my_read/my_realloc.
mysql-test/t/mysql.test:
  Test for bug#57450 was added.

Replace --debug with --loose-debug to prevent failure exit
Update: added workaround for 50627, skip all debugging of mysqlbinlog

handling.

The problem was that parsing of nested regular expression involved
recursive calls. Such recursion didn't take into account the amount of
available stack space, which ended up leading to stack overflow crashes.

mysql-test/t/not_embedded_server.test:
  Added test for bug#58026.
regex/my_regex.h:
  added pointer to function as last argument of my_regex_init() for check
  enough memory in stack.
regex/regcomp.c:
  p_ere() was modified: added call to function for check enough memory
  in stack. Function for check available stack space specified by
  global variable my_regex_enough_mem_in_stack. This variable set to
  NULL for embedded mysqld and to a pointer to function
  check_enough_stack_size otherwise.
regex/reginit.c:
  my_regex_init was modified: pass a pointer to a function for check
  enough memory in stack space. Reset this pointer to NULL in my_regex_end.
sql/mysqld.cc:
  Added function check_enough_stack_size() for check enough memory in stack.
  Passed this function as second argument to my_regex_init. For embedded 
  mysqld passed NULL as second argument.

When fixing the 27072 bug, the shell snippets running before/after
a RPM upgrade got expanded to look at files in the data directory
and at the PID file.
In this expansion, the standard locations were used.

There are users who configure their installations to use non-standard
locations for the data directory, the PID file, and other objects.
For these users, the fix of 27072 did not work.
As a result, the fact that a server was running at upgrade start was
not noticed, and the new server was not started after the upgrade.

With this patch, the shell snippets now try to get these locations
from "my_print_defaults" before falling back to the defaults.
Now, the fact that the old server is running is again noticed (even
with non-standard locations), and the new server is started.

Also, the upgrade log is written to the correct data directory.

support-files/mysql.spec.sh:
  See the global comment for the purpose of this change.
  
  In tests on SuSE 11, it was found necessary to use the full path name
  of "my_print_defaults", it seems $PATH die not include "/usr/bin".

      
There is one part of the test case that needs to break
and re-establish the circular topology. For this the test
stops the slave threads on a couple of servers and restarts
them with START SLAVE. However, no check is done on the
status of the IO or SQL threads before proceeding with
the subsequent commands.
      
Because rpl_only_running_threads is set to 1 this can lead
to silently not syncing all slave threads as expected, 
ultimately resulting in unexpected results (and consequently
on a failing test run).
      
We fix this by replacing the START SLAVE instructions with
calls to --source include/start_slave.inc, which will wait
for the slave threads to be running (show 'Yes' in 
Slave_IO|SQL_Running fields of SHOW SLAVE STATUS) before 
proceeding. Additionally, we change rpl_sync.inc to make the
IO thread report that it is running when its running status
is any other than 'No'.

Bug #55755 : Date STD variable signness breaks server on FreeBSD and OpenBSD

* Added a check to configure on the size of time_t
* Created a macro to check for a valid time_t that is safe to use with datetime 
  functions and store in TIMESTAMP columns.
* Used the macro consistently instead of the ad-hoc checks introduced by 52315
* Fixed compliation warnings on platforms where the size of time_t is smaller than
  the size of a long (e.g. OpenBSD 4.8 64 amd64).

Bug #52315: utc_date() crashes when system time > year 2037

* Added a correct check for the timestamp range instead of just variable size check to
SET TIMESTAMP.
* Added overflow checking before converting to time_t. 
* Using a correct localized error message in this case instead of the generic error.
* Added a test suite.
* fixed the checks so that they check for unsigned time_t as well. Used the checks 
  consistently across the source code.
* fixed the original test case to expect the new error code.

btr_rec_get_field_ref_offs(), btr_rec_get_field_ref(): New functions.
Get the pointer to an externally stored field.

btr_cur_set_ownership_of_extern_field(): Assert that the BLOB has not
already been disowned.

btr_store_big_rec_extern_fields(): Rename to
btr_store_big_rec_extern_fields_func() and add the debug parameter
update_in_place. All pointers to externally stored columns in the
record must either be zero or they must be pointers to inherited
columns, owned by this record or an earlier record version. For any
BLOB that is stored, the BLOB pointer must previously have been
zero. When the function completes, all BLOB pointers must be nonzero
and owned by the record.

primary_key_no == 0".

Attempt to create InnoDB table with non-nullable column of
geometry type having an unique key with length 12 on it and
with some other candidate key led to server crash due to
assertion failure in both non-debug and debug builds.

The problem was that such a non-candidate key could have
been sorted as the first key in table/.FRM, before any legit
candidate keys. This resulted in assertion failure in InnoDB
engine which assumes that primary key should either be the
first key in table/.FRM or should not exist at all.

The reason behind such an incorrect sorting was an wrong
value of Create_field::key_length member for geometry field
(which was set to its pack_length == 12) which confused code
in mysql_prepare_create_table(), so it would skip marking
such key as a key with partial segments.

This patch fixes the problem by ensuring that this member
gets the same value of Create_field::key_length member as 
for other blob fields (from which geometry field class is
inherited), and as result unique keys on geometry fields
are correctly marked as having partial segments.

sql/field.cc:
  Changed Create_field::create_length_to_internal_length() to
  correctly set Create_field::key_length member for geometry
  fields. Similar to the blob types key_length for such fields
  should be the same as length and not field's packed length
  (which is always 12 for geometry).
  
  As result of this change code handling table creation now
  always correctly identifies btree/unique keys on geometry
  fields as partial keys, so such keys can't be erroneously
  treated as candidate keys and sorted in keys array in .FRM
  before legit candidate keys.
  
  This fixes bug #58650 "Failing assertion: primary_key_no ==
  -1 || primary_key_no == 0" in which incorrect candidate key
  sorting led to assertion failure in InnoDB code.
