run_query_stmt() might use disable_xxx vars after calling handle_no_error
But handle_no_error() hes reverted any ONCE settings
Fix is to take revert_properties() out of handle_no_error()
Problem: commit_1innodb fails on pb2 after the patch for BUG#11758262
Background: Certain statements threw warnings only in statement mode causing
the result cintent mismatch.
Fix: disabled warnings from the statements.
Binary log of master can get a partially logged event if the server
runs out of disk space and, while waiting for some space to be freed,
is shut down (or crashes). If the server is not stopped, it will just
wait endlessly for space to be freed, thus no partial event anomaly
occurs. The restarted master server has had a dubious policy to send
the incomplete event to slave which it apparently can't handle.
Although an error was printed out the fact of sending with unclear
error message is a source of confusion.
Actually the problem of presence an incomplete event in the binary log
was already fixed by WL 5493 (which was merged to our current trunk
branch, major version 5.6). The fix makes the server truncate the
binary log on server restart and recovery.
However 5.5 master can't do that. So the current issue is a problem of
sending incomplete events to the slave by 5.5 master.
It is fixed in this patch by changing the policy so that only complete
events are pushed by the dump thread to the IO thread. In addition,
the error text that master sends to the slave when an incomplete event
is found, now states that incomplete event may have been caused by an
out-of-disk space situation and provides coordinates of
the first and the last event bytes read.

sql/share/errmsg-utf8.txt:
Increasing the explanatory part of ER_MASTER_FATAL_ERROR_READING_BINLOG error message twice
in order to fit to the updated version which carries some more info.
sql/sql_repl.cc:
Error text indicating a failure of reading from binlog that master delivers to the slave
is made more clear;
A policy to regard a partial event to send it out to the slave anyway is removed.
Problem: The following statements can cause the slave to go out of sync
if logged in statement format:
INSERT IGNORE...SELECT
INSERT ... SELECT ... ON DUPLICATE KEY UPDATE
REPLACE ... SELECT
UPDATE IGNORE :
CREATE ... IGNORE SELECT
CREATE ... REPLACE SELECT
Background: Since the order of the rows returned by the SELECT
statement or otherwise may differ on master and slave, therefore
the above statements may cuase the salve to go out of sync with
the master.
Fix:
Issue a warning when statements like the above are exectued and
the bin-logging format is statement. If the logging format is mixed,
use row based logging. Marking a statement as unsafe has been
done in the sql/sql_parse.cc instead of sql/sql_yacc.cc, because while
parsing for a token has been done we cannot be sure if the parsing
of the other tokens has been done as well.
Six new warning messages has been added for each unsafe statement.
binlog.binlog_unsafe.test has been updated to incoporate these additional unsafe statments.

mysql-test/extra/rpl_tests/rpl_insert_duplicate.test:

Warnings disabled for the unsafe statements.
mysql-test/extra/rpl_tests/rpl_insert_ignore.test:
1. Disabled warnings while for unsafe statements
2. As INSERT...IGNORE is an unsafe statement, an insert ignore not changing any rows,
will not be logged in the binary log, in the ROW and MIXED modes. It will however be logged
in STATEMENT mode.

SYSTEM VARIABLE NAME SQL_MAX_JOIN_SI
BACKGROUND:
ER_TOO_BIG_SELECT refers to SQL_MAX_JOIN_SIZE, which is the
old name for MAX_JOIN_SIZE.
FIX:
Support for old name SQL_MAX_JOIN_SIZE is removed in MySQL 5.6
and is renamed as MAX_JOIN_SIZE.So the errmsg.txt
and mysql.cc files have been updated and the corresponding result
files have also been updated.
CREATE_TIME IN INFORMATION_SC
It was impossible to determine MEMORY table creation time,
since it wasn't stored/exposed.
With this patch creation time is saved and it is available via
I_S.TABLES.CREATE_TIME.
Note: it was decided that additional analysis is required before
implementing UPDATE_TIME. Thus this patch doesn't store UPDATE_TIME.
Replace part of the patch that Kevin apparently forgot to push.
Fix the bug also in the built-in InnoDB of MySQL 5.1.
I cannot explain why the test case was not failing without the
full patch.
This was rb:762, approved by me.
Extra fix: 'if (p5 < p5_a + P5A_MAX)' is not portable.
p5 starts out pointing to a static array, then may point
to a buffer on the stack, then may point to malloc()ed memory.
The problem occurred when indexes are added between the time that an
UNDO record is created and the time that the purge thread comes around
and deletes the old secondary index entries. The purge thread would
hit an assert when trying to build a secondary index entry for
searching. The problem was that the old value of those fields were not
in the UNDO record since they were not part of an index when the UPDATE
occured.
A test case was added to innodb-index.test.

WITH MYSQL_REFRESH()
reset_slave_info.all was not initialized.
We fix this by setting lex->reset_slave_info.all= false in
the lex_start routine, which is called before every statement.

New test cases.

New test cases.
strings/dtoa.c:
Increasing the buffer size slightly made some queries pass without leaks.
Adding Bfree(p51, alloc) fixed the remaining leaks.
Added options --boot-gdb etc.
Extended gdb_arguments() with optional input argument
Cannot use set args in gdb init file, as run < <input> kills them (?)
For some reason the test authentication plugin accepted connection with arbitrary password. But the intention of the plugin is that password should equal to the authentication string and in the later versions of the server connection fails if password is wrong. So I have updated auth_rpl test to specify the correct password.
FULLTEXT INDEXES
myisamchk may create incorrect fulltext index for compressed

fulltext index.
