The task is to
(a) add a comment on indexes and
(b) increase the maximum length of column, table and the new index comments.
The patch committed on behalf of Yoshinori Matsunobu (Yoshinori.Matsunobu@Sun.COM).
A set of program options and variables was deprecated in
MySQL 5.1, and is hereby removed.
client/mysql.cc:
--no-auto-rehash (-A) is no longer deprecated
--no-named-commands (-g) is now removed
--skip-line-numbers (-L) is no longer deprecated
--set-variable (-O) is now removed
--no-pager is now removed
client/mysqlbinlog.cc:
--position is now removed (use --start-position)
-j is now equivalent with --start-position
client/mysqldump.c:
--first-slave is now removed
--no-set-names (-N) is now removed
--set-variable (-O) is now removed
mysql-test/include/default_mysqld.cnf:
default-character-set is removed as an option
character-set-server is equivalent.
mysql-test/t/bug47671-master.opt:
default-character-set option is removed
character-set-server is equivalent
mysql-test/t/ctype_latin1_de-master.opt:
default-character-set option is removed
character-set-server is equivalent
mysql-test/t/ctype_ucs2_def-master.opt:
default-collation is removed
collation-server is equicalent
scripts/mysqld_multi.sh:
--config-file has been superseded by
--defaults-extra-file
sql/mysql_priv.h:
Removed the version number in the deprecation
warning text, as decided by ServerPT.
sql/mysqld.cc:
--default-character-set (-C) is removed
--default-collation is removed
--log-long-format (-0) is removed
--safe-show-database is removed
--set-variable (-O) is removed
sql/sql_yacc.yy:
The FRAC_SECOND keyword is removed
sql/sys_vars.cc:
The sql_log_update system variable is removed
causing crashes!
Adding a SPATIAL INDEX on a non-geometrical column caused a
segmentation fault when the table was subsequently
inserted into.
A test was added in mysql_prepare_create_table to explicitly
check whether non-geometrical columns are used in a
spatial index, and throw an error if so.
mysql-test/t/gis.test:
Added test cases to verify that only geometrical
columns can get a spatial index.
In addition, verify that only a single geom.
column can participate in a spatial index.
mysql-test/t/disabled.def:
Restore disabled ssl tests: SSL certificates were updated.
Disable sp_sync.test, the test case can't work in next-4284.
mysql-test/t/partition_innodb.test:
Disable parsing of the test case for Bug#47343,
the test can not work in next-4284.
mysql-test/t/ps_ddl.test:
Update results (CREATE TABLE IF NOT EXISTS takes
into account existence of the temporary table).
Change the error code for ER_WARN_I_S_SKIPPED_TABLE, to not
upset the tests that rely on ER_SLAVE_CONVERSION_ERROR error
code = 1667.
Fix a merge bug with binlogging of CREATE TABLE (temporary tables).

BUG#46364 MyISAM transbuffer problems (NTM problem)
It is well-known that due to concurrency issues, a slave can become
inconsistent when a transaction contains updates to both transaction and
non-transactional tables.
In a nutshell, the current code-base tries to preserve causality among the
statements by writing non-transactional statements to the txn-cache which
is flushed upon commit. However, modifications done to non-transactional
tables on behalf of a transaction become immediately visible to other
connections but may not immediately get into the binary log and therefore
consistency may be broken.
In general, it is impossible to automatically detect causality/dependency
among statements by just analyzing the statements sent to the server. This
happen because dependency may be hidden in the application code and it is
necessary to know a priori all the statements processed in the context of
a transaction such as in a procedure. Moreover, even for the few cases that
we could automatically address in the server, the computation effort
required could make the approach infeasible.
So, in this patch we introduce the option
- "--binlog-direct-non-transactional-updates" that can be used to bypass
the current behavior in order to write directly to binary log statements
that change non-transactional tables.
Besides, it is used to enable the WL#2687 which is disabled by default.

The auto-inc unsafe warning makes sense even though it's just
one auto-inc table could be involved via a trigger or a stored
function.
However its content was not updated by bug@45677 fixes continuing to mention
two tables whereas the fixes refined semantics of replication of auto_increment
in stored routine.
Fixed with updating the error message, renaming the error and an internal unsafe-condition
constants.
A documentation notice
======================
Inserting into an autoincrement column in a stored function or a trigger
is unsafe for replication.
Even with just one autoincrement column, if the routine is invoked more than
once slave is not guaranteed to execute the statement graph same way as
the master.
And since it's impossible to estimate how many times a routine can be invoked at
the query pre-execution phase (see lock_tables), the statement is marked
pessimistically unsafe.

removed in MySQL 6.0
CREATE TABLE... TYPE= returns the warning "The syntax
'TYPE=storage_engine' is deprecated and will be removed in
MySQL 6.0. Please use 'ENGINE=storage_engine' instead"
This syntax is deprecated already from version 5.4.4, so
the message has been changed.
In addition, the deprecation macro was changed to reflect
the ServerPT decision not to include version number in the
warning message.
A number of test result files have been changed as a
consequence of the change in the deprecation macro.
using cmake option INSTALL_LAYOUT=STANDALONE would produce the layout as in
tar.gz or zip packages.
INSTALL_LAYOUT=UNIX will produce unixish install layout (with mysqld being in sbin subdirectory , libs in lib/mysql etc). This layout is used for RPM packages.
Subtle differences in both packages unfortunately lead to the need to recompile MySQL to use with other package type - as otherwise for example default plugins or data directories would be wrong set.
There are numerous other variables that allow fine-tuning packaging layout. (INSTALL_BINDIR, INSTALL_LIBDIR , INSTALL_PLUGINDIR etc).
This options are different from autotools as they do not expect full paths to directories, but only subdirectory of CMAKE_INSTALL_PREFIX.
There are 2 special options that expect full directory paths
- MYSQL_DATADIR that defines default MYSQL data directory (autotools equivalent
is --localstatedir)
- SYSCONFDIR can be added to search my.cnf search path (autotools equivalent is --sysconfdir)

that change non-transactional tables.

mysql-test/extra/rpl_tests/rpl_binlog_max_cache_size.test:
Changes the result set as the STMT mode behaves as both the ROW and MIXED modes and as such uses the non-trx-cache and takes longer to fill the trx-cache up and trigger an error.
mysql-test/extra/rpl_tests/rpl_implicit_commit_binlog.test:
Changes the result set as the STMT mode behaves as both the ROW and MIXED modes and as such uses the non-trx-cache. It also fixes comments.
mysql-test/extra/rpl_tests/rpl_mixing_engines.test:
The STMT mode is unsafe when mixed-statements are executed thus making slaves to go out of sync. For that reason, it checks consistency if not in STMT mode.

the option is disabled.
Several items said to be deprecated in the 4.1 manual
have never been removed. This worklog adds deprecation
warnings when these items are used, and warns the user
that the items will be removed in MySQL 5.6.
A couple of previously deprecation decision have been
reversed (see single file comments)
client/client_priv.h:
Macro similar to the one in the server (mysql_priv.h)
for printing a deprecation warning message
client/mysql.cc:
no-auto-rehash will not be deprecated
skip-line-numbers will not be deprecated
skip-column-names will not be deprecated
no-pager is deprecated
set-variable is deprecated
no-named-commands is deprecated
client/mysqladmin.cc:
set-variable is deprecated
client/mysqlbinlog.cc:
position is deprecated
client/mysqldump.c:
first-slave is deprecated
no-set-names is deprecated
set-variable is deprecated
mysql-test/r/mysqlbinlog.result:
Adding the [Warning] to the test case, just to show that the
deprecation works.
The test case will be changed in Celosia to use --start-position.
mysys/my_getopt.c:
set-variable (include -O) is deprecated
scripts/mysqld_multi.sh:
Warning for mysqld_multi
sql/mysqld.cc:
default-collation is deprecated
log-bin-trust-routine-creators is deprecated
set-variable is deprecated
default-character-set is deprecated
safe-show-database is deprecated
sql/share/errmsg.txt:
Added version number for sql_log_update deprecation message.
Problem: The test case failed because: (i) warning text in
result file differed from the warning output by the
server, and (ii) binlog contents in result file did
not show the statements logged wrapped in BEGIN/COMMIT
as it is the case after WL 2687.
Solution: We update the result file, but first we change the
unsafe warning text to also refer to performance_schema
table(s). This required changing the result files for
existing test cases that provide output for warnings
related to ER_BINLOG_UNSAFE_SYSTEM_TABLE. "Grepping" in
result files, shows that only binlog_unsafe contained
reference to such a warning.
We also update the result file with the missing
BEGIN/COMMIT statements.
