archive_discover
Fixed buffer underrun in cleanup_dirname().
Also fixed that original (unencoded) database and table
names were used to discover archive tables.

Fixed buffer underrun in cleanup_dirname(), when
it gets path like "a/../" (relative path, where
first directory is to be cut off).

Handler discover method gets database and table
names as is. It must use build_table_filename()
to get name similar to what it gets on create()

It is not necessary to support INSERT DELAYED for a single value insert,
while we do not support that for multi-values insert when binlog is
enabled in SBR.
The lock_type is upgrade to TL_WRITE from TL_WRITE_DELAYED for
INSERT DELAYED for single value insert as multi-values insert
did when binlog is enabled. Then it's safe. And binlog it as
INSERT without DELAYED.

sql/sql_insert.cc:
Updated code for the following things:
1. Upgrade the lock_type to TL_WRITE from TL_WRITE_DELAYED
for INSERT DELAYED for single value insert as multi-values
insert did when binlog is enabled.
2. Clear code to not binlog INSERT DELAYED STMT in SBR.
3. Get rid of privilege check for log_on.
When using BINLOG statement to execute rows log events, session variables
foreign_key_checks and unique_checks are changed temporarily. As each rows
log event has their own special session environment and its own
foreign_key_checks and unique_checks can be different from current session
which executing the BINLOG statement. But these variables are not restored
correctly after BINLOG statement. This problem will cause that the following
statements fail or generate unexpected data.
In this patch, code is added to backup and restore these two variables.
So BINLOG statement will not affect current session's variables again.

After dropping and recreating the database specified along with --one-database
option at command line, mysql client keeps filtering the statements even after
the execution of a 'USE' command on the same database.
--one-database option enables the filtering of statements when the current
database is not the one specified at the command line. However, when the same
database is dropped and recreated the variable (current_db) that holds the
inital database name gets altered. This bug exploits the fact that current_db
initially gets set to null value (0) when a 'use db_name' follows the recreation
of same database db_name (speficied at the command line) and hence skip_updates
gets set to 1, which inturn triggers the further filtering of statements.
Fixed by making get_current_db() a no-op function when one_database is set,
and hence, under that condition current_db will not get altered.
Note, however the value of current_db can change when we execute 'connect'
command with a differnet database to reconnect to the server, in which case,
the behavior of --one-database will be formulated using this new database.
client/mysql.cc:
Bug #54899 : --one-database option cannot handle DROP/CREATE DATABASE commands
Added an if statement at the beginnning of get_current_db() , which makes it
a no-op function if one-database option is specified, and hence current_db
remains unchanged.
Changed the help message for one-database option to a more appropriate message
as specified in mysql documentation.
mysql-test/r/mysql.result:
Added a test case for bug#54899 and some more test cases to
check other one-database option related behaviors.

Problem: LIKE over an indexed column optimized away good results,
because my_like_range_utf32/utf16 returned wrong ranges for contractions.
Contraction related code was missing in my_like_range_utf32/utf16,
but did exist in my_like_range_ucs2/utf8.
It was forgotten in utf32/utf16 versions (during mysql-6.0 push/revert mess).
Fix:
The patch removes individual functions my_like_range_ucs2,
my_like_range_utf16, my_like_range_utf32 and introduces a single function
my_like_range_generic() instead. The new function handles contractions
correctly. It can handle any character set with cs->min_sort_char and
cs->max_sort_char represented in Unicode code points.

@ strings/ctype-ucs2.c
- my_fill_mb2 did not put the high byte, as previously
it was used to put only characters in ASCII range.
Now it puts high byte as well
(needed to pupulate cs->max_sort_char correctly).
- Adding DBUG_ASSERT()
- Removing character set specific functions:
my_like_range_ucs2(), my_like_range_utf16() and my_like_range_utf32().
- Using my_like_range_generic() instead of the old functions.

works correctly for all character sets and collations.
It does work in general, the problem here was that the test name
'alter_table' matches 'main.alter_table-big' which has already been found.
Fixed by matching more explicitly (with/without suite name)
(we don't need to port the actual code from 5.1;
5.5+ do the relevant things differently, but correctly. the
test obviously is so it stays that way.)

If mysqltest dies, mtr waits to see if mysqld dies too within 100ms

In case of low memory sort buffer QUICK_INDEX_MERGE_SELECT creates
temporary file where is stores row ids which meet QUICK_SELECT ranges
except of clustered pk range, clustered range is processed separately.
In init_read_record we check if temporary file is used and choose
appropriate record access method. It does not take into account that
temporary file contains partial result in case of QUICK_INDEX_MERGE_SELECT
with clustered pk range.
The fix is always to use rr_quick if QUICK_INDEX_MERGE_SELECT
with clustered pk range is used.

The autotools-based build system has been superseded and
is being removed in order to ease the maintenance burden on
developers tweaking and maintaining the build system.
In order to support tools that need to extract the server
version, a new file that (only) contains the server version,
called VERSION, is introduced. The file contents are human
and machine-readable. The format is:
MYSQL_VERSION_MAJOR=5
MYSQL_VERSION_MINOR=5
MYSQL_VERSION_PATCH=8
MYSQL_VERSION_EXTRA=-rc
The CMake based version extraction in cmake/mysql_version.cmake
is changed to extract the version from this file. The configure
to CMake wrapper is retained for backwards compatibility and to
support the BUILD/ scripts. Also, a new a makefile target
show-dist-name that prints the server version is introduced.
VERSION:
Add top-level version file.
cmake/mysql_version.cmake:
Get version information from the top-level VERSION file.
Do not cache the version components (MAJOR_VERSION, etc).
Add MYSQL_RPM_VERSION as a replacement for MYSQL_U_SCORE_VERSION.
Regression introduced by WL#2649.
Problem: queries with date/datetime columns did not use indexes:
set names non_latin1_charset;
select * from date_index_test
where date_column between '2010-09-01' and '2010-10-01';
before WL#2649 indexes worked fine because charset of
date/datetime
columns was BINARY which always won.
Fix: testing that collation of the operation matches collation
of the field is only needed in case of "real" string data types.
For DATE, DATETIME it's not needed.

Updated the server to treat a missing mysql.proxies_priv table
as empty.
Added some grants to make sure tables are correctly opened
when they must be opened.
Fixed a mysql_upgrade omission not adding rights to root to
execute GRANT PROXY on other users.
Removed a redundant CREATE TABLE from
mysql_system_tables_fix.sql since it's always executed after
mysql_system_tables.sql and the first file has CREATE TABLE
in it.
Added a test case for the above.
Fixed error handling code to close the cursor
leave the table unusable".
Failing ALTER statement on partitioned table could have left
this table in an unusable state. This has happened in cases
when ALTER was executed using "fast" algorithm, which doesn't
involve copying of data between old and new versions of table,
and the resulting new table was incompatible with partitioning
function in some way.
The problem stems from the fact that discrepancies between new
table definition and partitioning function are discovered only
when the table is opened. In case of "fast" algorithm this has
happened too late during ALTER's execution, at the moment when
all changes were already done and couldn't have been reverted.
In the cases when "slow" algorithm, which copies data, is used
such discrepancies are detected at the moment new table
definition is opened implicitly when new version of table is
created in storage engine. As result ALTER is aborted before
any changes to table were done.
This fix tries to address this issue by ensuring that "fast"
algorithm behaves similarly to "slow" algorithm and checks
compatibility between new definition and partitioning function
by trying to open new definition after .FRM file for it has
been created.
Long term we probably should implement some way to check
compatibility between partitioning function and new table
definition which won't involve opening it, as this should
allow much cleaner fix for this problem.
mysql-test/r/partition_innodb.result:
Added test for bug #57985 "ONLINE/FAST ALTER PARTITION can
fail and leave the table unusable".
mysql-test/t/partition_innodb.test:
Added test for bug #57985 "ONLINE/FAST ALTER PARTITION can
fail and leave the table unusable".
sql/sql_table.cc:
Ensure that in cases when .FRM for partitioned table is
created without creating table in storage engine (e.g.
during "fast" ALTER TABLE) we still open table definition.
This allows to check that definition of created table/.FRM
is compatible with its partitioning function.
