Remove custom DLL loader code from innodb plugin code, use
symbols exported from mysqld.
storage/innodb_plugin/handler/ha_innodb.cc:
Remove a Win32 workaround for current_thd.
The original problem that innodb plugin used
value of TLS variable across DLL boundaries is
solved in MySQL server (current_thd is a function
not TLS variable now)
storage/innodb_plugin/handler/handler0alter.cc:
Remove custom delay loader
storage/innodb_plugin/handler/handler0vars.h:
Remove custom delay loader
storage/innodb_plugin/handler/i_s.cc:
Remove custom delay loader
storage/innodb_plugin/handler/win_delay_loader.cc:
Remove custom delay loader
storage/innodb_plugin/plug.in:
Remove commented out MYSQL_PLUGIN_STATIC,
CMake would not parse that correctly
The Innodb plugin 1.0.4 can be installed dynamically using the 'INSTALL PLUGIN' syntax
If mysqld is already statically linked with the inbuilt innodb, it is not possible to
install the innodb plugin 1.0.4 dynamically. Doing so would throw this error - Function
'innodb' already exists.
storage/innodb_plugin/Makefile.am:
Remove references of 'storage/innobase' and use $(srcdir) instead.
Renamed the dynamic plugin library name to 'ha_innodb_plugin' so
that it can be installed along with inbuilt plugin.
storage/innodb_plugin/Makefile.in:
Remove this file as it can be generated automatically by automake
using the Makefile.am
storage/innodb_plugin/handler/ha_innodb.cc:
Remove refernces to "storage/innobase" and the headers can be included directly.
Declare the plugin with the new name innodb_plugin
storage/innodb_plugin/plug.in:
Rename the plugin innobase as innodb_plugin
On 64-bit Windows: querying MERGE table with keys may cause
server crash.The problem is generic and may affect any statement
accessing MERGE table cardinality values.
When MERGE engine was copying cardinality statistics, it was
using incorrect size of element in cardinality statistics array
(sizeof(ptr)==8 instead of sizeof(ulong)==4), causing access
of memory beyond of the allocated bounds.
sql/ha_myisam.cc:
When copying rec_per_key array (an array of ulong) use proper
size of element, that is sizeof(ulong).
sql/ha_myisammrg.cc:
When copying rec_per_key array (an array of ulong) use proper
size of element, that is sizeof(ulong).
sql/table.cc:
When allocating rec_per_key array (an array of ulong) use proper
size of element, that is sizeof(ulong).
The fix is to allow myisamchk to use >4G key_buffer_size on win64
include/myisam.h:
use ulonglong instead of ulong for use_buffers
storage/myisam/myisamchk.c:
use ulonglong instead of ulong for use_buffers
doesn't find 'logger'
Due to a variable quoting mistake, the $PATH environment
variable isn't parsed correctly when searching for the
existence of the desired executable(s) (logger in this
case).
This patch removes the quotes.
The problem is that the server failed to follow the rule that
every X509 object retrieved using SSL_get_peer_certificate()
must be explicitly freed by X509_free(). This caused a memory
leak for builds linked against OpenSSL where the X509 object
is reference counted -- improper counting will prevent the
object from being destroyed once the session containing the
peer certificate is freed.
The solution is to explicitly free every X509 object used.
mysql-test/r/openssl_1.result:
Add test case result for Bug#42158
mysql-test/t/openssl_1.test:
Add test case for Bug#42158
sql/sql_acl.cc:
Deallocate X509 objects.
HAVING
When calculating GROUP BY the server caches some expressions. It does
that by allocating a string slot (Item_copy_string) and assigning the
value of the expression to it. This effectively means that the result
type of the expression can be changed from whatever it was to a string.
As this substitution takes place after the compile-time result type
calculation for IN but before the run-time type calculations,
it causes the type calculations in the IN function done at run time
to get unexpected results different from what was prepared at compile time.
In the CASE ... WHEN ... THEN ... statement there was a similar problem
and it was solved by artificially adding a STRING argument to the set of
types of the IN/CASE arguments at compile time, so if any of the
arguments of the CASE function changes its type to a string it will
still be covered by the information prepared at compile time.

stop/start slave
When stopping and restarting the slave while it is replicating
temporary tables, the server would crash or raise an assertion
failure. This was due to the fact that although temporary tables are
saved between slave threads restart, the reference to the thread in
use (table->in_use) was not being properly updated when the restart
happened (it would still reference the old/invalid thread instead of
the new one).
This patch addresses this issue by resetting the reference to the new
slave thread on slave thread restart.
mysql-test/r/rpl_temporary.result:
Result file.
mysql-test/t/rpl_temporary.test:
Test case that checks that both failures go away.
sql/slave.cc:
Changed slave.cc to reset sql_thd reference in temporary tables.
Created new .test file - mysqldump_restore that does test restore from mysqldump
output for a limited number of basic cases.
Create new .inc file - mysqldump.inc - renames original table and uses mysqldump
output to recreate the table, then uses diff_tables.inc to compare the two tables.
Backported include/diff_tables.inc to facilitate this testing.
New patch incorporating review feedback prior to push.
mysqldump.test - removed redundant call to include/have_log_bin.inc (was used twice in the test!)
assertion .\filesort.cc, line 797
A query with the "ORDER BY @@some_system_variable" clause,
where @@some_system_variable is NULL, causes assertion
failure in the filesort procedures.
The reason of the failure is in the value of
Item_func_get_system_var::maybe_null: it was unconditionally
set to false even if the value of a variable was NULL.

Bug #42778: delete order by null global variable causes
assertion .\filesort.cc, line 797
The longlong_from_string_with_check function has been modified
to skip unwanted warnings: now it uses the THD::no_errors
flag to suppress warnings.
The Item_func_get_system_var::update_null_value method
sets the no_error flag.
sql/item_func.cc:
Bug #42778: delete order by null global variable causes
assertion .\filesort.cc, line 797
1. The Item_func_get_system_var::fix_length_and_dec method
has been modified to make system variables truly nullable.
2. The Item_func_get_system_var::update_null_value method
method has been overloaded with a simple wrapper (like
Item_field::update_null_value) to suppress unwanted warnings
from Item_func_get_system_var::val_int() calls on non-numeric
variable values: the Item_func_get_system_var::update_null_value
method sets and restores THD::no_errors flag for a nested
call of the longlong_from_string_with_check function.
sql/item_func.h:
Bug #42778: delete order by null global variable causes

Created new .test file - mysqldump_restore that does this for a limited number
of basic cases.
Created new .inc file - mysqldump.inc - renames original table and uses mysqldump
output to recreate the table, then uses diff_tables.inc to compare the two tables.
Backported include/diff_tables.inc to facilitate this testing.
