ffa7e0fabe MWL#116: Efficient group commit: Fix bug that binlog pos stored by XtraDB during commit was wrong when more than one commit in group.
Now the actual binlog position for each commit is stored in THD, and XtraDB
can fetch the correct value from within commit_ordered() or commit().

211552ccee Bug#56118 STOP SLAVE does not wait till trx with CREATE TMP TABLE ends,
replication aborts

When recieving a 'SLAVE STOP' command, slave SQL thread will roll back the
transaction and stop immidiately if there is only transactional table updated,
even through 'CREATE|DROP TEMPOARY TABLE' statement are in it. But These
statements can never be rolled back. Because the temporary tables to the user
session mapping remain until 'RESET SLAVE', Therefore it will abort SQL thread
with an error that the table already exists or doesn't exist, when it restarts
and executes the whole transaction again.

After this patch, SQL thread always waits till the transaction ends and then stops,
if 'CREATE|DROP TEMPOARY TABLE' statement are in it.

sql/slave.cc:

a4fff491eb Fix that one can run mysql_upgrade with long table names
Fall back to use ALTER TABLE for engines that doesn't support REPAIR when doing repair for upgrade.

9d6811502e WL#5370 Keep forward-compatibility when changing
'CREATE TABLE IF NOT EXISTS ... SELECT' behaviour
BUG#55474, BUG#55499, BUG#55598, BUG#55616 and BUG#55777 are fixed
in this patch too.

This is the 5.1 part.
It implements:
- if the table exists, binlog two events: CREATE TABLE IF NOT EXISTS
  and INSERT ... SELECT

- Insert nothing and binlog nothing on master if the existing object
  is a view. It only generates a warning that table already exists.


mysql-test/r/trigger.result:
  Ather this patch, 'CREATE TABLE IF NOT EXISTS ... SELECT' will not
  insert anything if the creating table already exists and is a view.
sql/sql_class.h:
  Declare virtual function write_to_binlog() for select_insert.
  It's used to binlog 'create select'
sql/sql_insert.cc:
  Implement write_to_binlog();
  Use write_to_binlog() instead of binlog_query() to binlog the statement.
  if the table exists, binlog two events: CREATE TABLE IF NOT EXISTS
  and INSERT ... SELECT
sql/sql_lex.h:
  Declare create_select_start_with_brace and create_select_pos.
  They are helpful for binlogging 'create select'
sql/sql_parse.cc:
  Do nothing on master if the existing object is a view.
sql/sql_yacc.yy:
  Record the relative postion of 'SELECT' in the 'CREATE ...SELECT' statement.
  Record whether there is a '(' before the 'SELECT' clause.

2124538d9c BUG#49124 Security issue with /*!-versioned */ SQL statements on Slave
/*![:version:] Query Code */, where [:version:] is a sequence of 5 
digits representing the mysql server version(e.g /*!50200 ... */),
is a special comment that the query in it can be executed on those 
servers whose versions are larger than the version appearing in the 
comment. It leads to a security issue when slave's version is larger 
than master's. A malicious user can improve his privileges on slaves. 
Because slave SQL thread is running with SUPER privileges, so it can
execute queries that he/she does not have privileges on master.

This bug is fixed with the logic below: 
- To replace '!' with ' ' in the magic comments which are not applied on
  master. So they become common comments and will not be applied on slave.

- Example:
  'INSERT INTO t1 VALUES (1) /*!10000, (2)*/ /*!99999 ,(3)*/
  will be binlogged as
  'INSERT INTO t1 VALUES (1) /*!10000, (2)*/ /* 99999 ,(3)*/

  this patch.
  Add member function yyUnput for Lex_input_stream. It set a character back the query buff.

0f9ddfa9d8 Bug#42733: Type-punning warnings when compiling MySQL --
strict aliasing violations.

One somewhat major source of strict-aliasing violations and
related warnings is the SQL_LIST structure. For example,
consider its member function `link_in_list` which takes
a pointer to pointer of type T (any type) as a pointer to
pointer to unsigned char. Dereferencing this pointer, which
is done to reset the next field, violates strict-aliasing
rules and might cause problems for surrounding code that
uses the next field of the object being added to the list.

The solution is to use templates to parametrize the SQL_LIST
structure in order to deference the pointers with compatible
types. As a side bonus, it becomes possible to remove quite
a few casts related to acessing data members of SQL_LIST.

sql/handler.h:
  Use the appropriate template type argument.
sql/item.cc:
  Remove now-unnecessary cast.
sql/item_subselect.cc:
  Remove now-unnecessary casts.
sql/item_sum.cc:
  Use the appropriate template type argument.
  Remove now-unnecessary cast.
sql/mysql_priv.h:
  Move SQL_LIST structure to sql_list.h
  Use the appropriate template type argument.
sql/sp.cc:
  Remove now-unnecessary casts.
sql/sql_delete.cc:
  Use the appropriate template type argument.
  Remove now-unnecessary casts.
sql/sql_derived.cc:
  Remove now-unnecessary casts.
sql/sql_lex.cc:
  Remove now-unnecessary casts.
sql/sql_lex.h:
  SQL_LIST now takes a template type argument which must
  match the type of the elements of the list. Use forward
  declaration when the type is not available, it is used
  in pointers anyway.
sql/sql_list.h:
  Rename SQL_LIST to SQL_I_List. The template parameter is
  the type of object that is stored in the list.
sql/sql_olap.cc:
  Remove now-unnecessary casts.
sql/sql_parse.cc:
  Remove now-unnecessary casts.

c2ebb0ac88 Bug #42064: low memory crash when importing hex strings, in
Item_hex_string::Item_hex_string

The status of memory allocation in the Lex_input_stream (called
from the Parser_state constructor) was not checked which led to
a parser crash in case of the out-of-memory error.

The solution is to introduce new init() member function in
Parser_state and Lex_input_stream so that status of memory
allocation can be returned to the caller.

3f8bde448c BUG#53560 CREATE TEMP./DROP TEMP. are not binglogged correctly after a failed statement
This patch fixes two problems described as follows:

1 - If there is an on-going transaction and a temporary table is created or
dropped, any failed statement that follows the "create" or "drop commands"
triggers a rollback and by consequence the slave will go out sync because
the binary log will have a wrong sequence of events.

To fix the problem, we changed the expression that evaluates when the
cache should be flushed after either the rollback of a statment or
transaction.

2 - When a "CREATE TEMPORARY TABLE SELECT * FROM" was executed the
OPTION_KEEP_LOG was not set into the thd->options. For that reason, if
the transaction had updated only transactional engines and was rolled
back at the end (.e.g due to a deadlock) the changes were not written
to the binary log, including the creation of the temporary table.
      
To fix the problem, we have set the OPTION_KEEP_LOG into the thd->options
when a "CREATE TEMPORARY TABLE SELECT * FROM" is executed.

sql/log.cc:
  Reorganized the code based on the following functions:
  
  - bool ending_trans(const THD* thd, const bool all);
  - bool trans_has_updated_non_trans_table(const THD* thd);
  - bool trans_has_no_stmt_committed(const THD* thd, const bool all);
  - bool stmt_has_updated_non_trans_table(const THD* thd);
sql/log.h:
  Added functions to organize the code in log.cc.
sql/log_event.cc:
  Removed the OPTION_KEEP_LOG since it must be used only when
  creating and dropping temporary tables.
sql/log_event_old.cc:
  Removed the OPTION_KEEP_LOG since it must be used only when
  creating and dropping temporary tables.
sql/sql_parse.cc:

79e60f0a40 Bug#48157: crash in Item_field::used_tables
MySQL handles the join syntax "JOIN ... USING( field1,
... )" and natural joins by building the same parse tree as
a corresponding join with an "ON t1.field1 = t2.field1 ..."
expression would produce. This parse tree was not cleaned up
properly in the following scenario. If a thread tries to
lock some tables and finds that the tables were dropped and
re-created while waiting for the lock, it cleans up column
references in the statement by means a per-statement free
list. But if the statement was part of a stored procedure,
column references on the stored procedure's free list
weren't cleaned up and thus contained pointers to freed
objects.
      
Fixed by adding a call to clean up the current prepared
statement's free list.

This is a backport from MySQL 5.1

71b453fa06 Bug #53371: COM_FIELD_LIST can be abused to bypass table level grants.
This is the 5.1 merge and extension of the fix.
The server was happily accepting paths in table name in all places a table
name is accepted (e.g. a SELECT). This allowed all users that have some 
privilege over some database to read all tables in all databases in all
mysql server instances that the server file system has access to.
Fixed by :
1. making sure no path elements are allowed in quoted table name when
constructing the path (note that the path symbols are still valid in table names
when they're properly escaped by the server).
2. checking the #mysql50# prefixed names the same way they're checked for
path elements in mysql-5.0.

54705ab176 Bug#50974: Server keeps receiving big (> max_allowed_packet) packets indefinitely.
The server could be tricked to read packets indefinitely if it
received a packet larger than the maximum size of one packet.
This problem is aggravated by the fact that it can be triggered
before authentication.

The solution is to no skip big packets for non-authenticated
sessions. If a big packet is sent before a session is authen-
ticated, a error is returned and the connection is closed.

e925bd737f BUG#48632: Fix for Bug #23300 Has Not Been Backported
To 5.x Release
      
Notes
=====
      
This is a backport of BUG#23300 into 5.1 GA.
      
Original cset revid (in betony):
luis.soares@sun.com-20090929140901-s4kjtl3iiyy4ls2h

Description
===========
      
When using replication, the slave will not log any slow query
logs queries replicated from the master, even if the
option "--log-slow-slave-statements" is set and these take more
than "log_query_time" to execute.
                    
In order to log slow queries in replicated thread one needs to
set the --log-slow-slave-statements, so that the SQL thread is
initialized with the correct switch. Although setting this flag
correctly configures the slave thread option to log slow queries,
there is an issue with the condition that is used to check
whether to log the slow query or not. When replaying binlog
events the statement contains the SET TIMESTAMP clause which will
force the slow logging condition check to fail. Consequently, the
slow query logging will not take place.
                    
This patch addresses this issue by removing the second condition
from the log_slow_statements as it prevents slow queries to be
binlogged and seems to be deprecated.

REORGANIZE PARTITION

There were several problems which lead to this this,
all related to bad error handling.

1) There was several bugs preventing the ddl-log to be used for
   cleaning up created files on error.

2) The error handling after the copy partition rows did not close
   and unlock the tables, resulting in deletion of partitions
   which were in use, which lead InnoDB to put the partition to
   drop in a background queue.

377d710296 BUG#47418 RBR fails, failure with mixup of base/temporary/view
'CREATE TABLE IF NOT EXISTS ... SELECT' statement were causing 'CREATE
TEMPORARY TABLE ...' to be written to the binary log in row-based 
mode (a.k.a. RBR), when there was a temporary table with the same name.
Because the 'CREATE TABLE ... SELECT' statement was executed as 
'INSERT ... SELECT' into the temporary table. Since in RBR mode no 
other statements related to temporary tables are written into binary log,
this sometimes broke replication.

This patch changes behavior of 'CREATE TABLE [IF NOT EXISTS] ... SELECT ...'.
it ignores existence of temporary table with the 
same name as table being created and is interpreted
as attempt to create/insert into base table. This makes behavior of
'CREATE TABLE [IF NOT EXISTS] ... SELECT' consistent with
how ordinary 'CREATE TABLE' and 'CREATE TABLE ... LIKE' behave.

b3dd4d9486 Bug#33982 debug assertion and crash reloading grant tables after sighup or kill
In certain rare cases when a process was interrupted
during a FLUSH PRIVILEGES operation the diagnostic
area would be set to an error state but the function
responsible for the operation would still signal
success. This would lead to a debug assertion error
later on when the server would attempt to reset the
DA before sending the error message.

This patch fixes the issue by assuring that
reload_acl_and_cache() always fails if an error
condition is raised.

The second issue was that a KILL could cause
a console error message which referred to a DA
state without first making sure that such a
state existed.

This patch fixes this issue in two different
palces by first checking DA state before
fetching the error message.

 

sql/sql_acl.cc:
  * Make sure that there is an error to print before attempting to do so.
  * Minor style change: change 1 to TRUE for clarity.
sql/sql_parse.cc:
  * Always fail reload_acl_and_cache() if the query was killed.
sql/sql_servers.cc:
  * Make sure that there is an error to print before attempting to do so.

c8b5804f29 Bug#48157: crash in Item_field::used_tables
MySQL handles the join syntax "JOIN ... USING( field1,
... )" and natural joins by building the same parse tree as
a corresponding join with an "ON t1.field1 = t2.field1 ..."
expression would produce. This parse tree was not cleaned up
properly in the following scenario. If a thread tries to
lock some tables and finds that the tables were dropped and
re-created while waiting for the lock, it cleans up column
references in the statement by means a per-statement free
list. But if the statement was part of a stored procedure,
column references on the stored procedure's free list weren't
cleaned up and thus contained pointers to freed objects.

Fixed by adding a call to clean up the current prepared
statement's free list.

be397eb400 Bug #49137 Replication failure on SBR/MBR + multi-table DROP TEMPORARY TABLE
In statement-based or mixed-mode replication, use DROP TEMPORARY TABLE
to drop multiple tables causes different errors on master and slave, 
when one or more of these tables do not exist. Because when executed
on slave, it would automatically add IF EXISTS to the query to ignore
all ER_BAD_TABLE_ERROR errors.

To fix the problem, do not add IF EXISTS when executing DROP TEMPORARY
TABLE on the slave, and clear the ER_BAD_TABLE_ERROR error after
execution if the query does not expect any errors.

mysql-test/suite/rpl/r/rpl_drop_temp.result:
  Updated for the patch of bug#49137.
mysql-test/suite/rpl/t/rpl_drop_temp.test:
  Added the test file to verify if DROP MULTI TEMPORARY TABLE
  will cause different errors on master and slave, when one or
  more of these tables do not exist.
sql/log_event.cc:
  Added code to handle above cases which are 
  removed from sql_parse.cc
sql/sql_parse.cc:
  Remove the code to issue the 'Unknown table' error, 
  if the temporary table does not exist when dropping 
  it on slave. The above cases decribed in comments
  will be handled later in log_event.cc.

06a1df9181 Bug#48983: Bad strmake calls (length one too long)
The problem is a somewhat common misusage of the strmake function.
The strmake(dst, src, len) function writes at most /len/ bytes to
the string pointed to by src, not including the trailing null byte.
Hence, if /len/ is the exact length of the destination buffer, a
one byte buffer overflow can occur if the length of the source
string is equal to or greater than /len/.

client/mysqldump.c:
  Make room for the trailing null byte.
libmysql/libmysql.c:
  Add comment, there is enough room in the buffer.
  Increase buffer length, two strings are concatenated.
libmysqld/lib_sql.cc:
  Make room for the trailing null byte.
mysys/default.c:
  Make room for the trailing null bytes.

  Make room for the trailing null byte.
sql/log.cc:

sql/sp_pcontext.h:
  Cosmetic fix.

  MAX_HOSTNAME already specifies space for the trailing null byte.

- Did changes in pbxt and maria storage engines becasue of changes in thd->query
- Reverted wrong code in sql_table.cc for how ROW_FORMAT is used.

This is a re-commit of Monty's merge to eliminate an extra commit from

This is a merge of the MySQL 5.1.41 clone-off (clone-5.1.41-build). In

CURRENT_USER() in GRANT ... TO CURRENT_USER() only gave us a definer,

dereferencing the password led to a crash.
