This patch:
- Moves all definitions from the mysql_priv.h file into
header files for the component where the variable is
defined
- Creates header files if the component lacks one
- Eliminates all include directives from mysql_priv.h
- Eliminates all circular include cycles
- Rename time.cc to sql_time.cc
- Rename mysql_priv.h to sql_priv.h

Before this fix, client tools (mysql_upgrade, mysqlcheck, mysqldump)
would try to process performance schema tables, leading to failures.
The fix is to align FIRST_PERFORMANCE_SCHEMA_VERSION to 5.5.3,
which is the version number of mysql-trunk where the
performance schema is first available.
mysql_upgrade was passing an non-initialized non-null tmpdir to create_temp_file() if no
--tmpdir was specified. This prevents create_temp_file() from taking the system
temporary file path and as a result mysql_upgrade was trying to open a file in a
directory that it may not have write access to.
Fixed by making sure mysql_upgrade will pass a zero length temp dir string to
create_temp_file() if no --tmpdir is specified.
The problem was that mysqltest could attempt to execute a
SHOW WARNINGS statement through a connection that was not
properly reaped, thus violating its own rules.
The solution is to skip SHOW WARNINGS if a connection has
not been properly repeaed.
client/mysqltest.cc:
Skip SHOW WARNINGS if connection hasn't been reaped.
I found three issues during the analysis:
1. Memory leak caused by temp_buf not being freed;
2. Memory leak caused when handling argv;
3. Conditional jump that depended on unitialized values.
Issue #1
--------
DESCRIPTION: when mysqlbinlog is reading from a remote location
the event temp_buf references the incoming stream (in NET
object), which is not freed by mysqlbinlog explicitly. On the
other hand, when it is reading local binary log, it points to a
temporary buffer that needs to be explicitly freed. For both
cases, the temp_buf was not freed by mysqlbinlog, instead was
set to 0. This clearly disregards the free required in the
second case, thence creating a memory leak.
FIX: we make temp_buf to be conditionally freed depending on
the value of remote_opt. Found out that similar fix is already
in most recent codebases.
Issue #2
--------
DESCRIPTION: load_defaults is called by parse_args, and it
reads default options from configuration files and put them
BEFORE the arguments that are already in argc and argv. This is
done resorting to MEM_ROOT. However, parse_args calls
handle_options immediately after which changes argv. Later when
freeing the defaults, pointers to MEM_ROOT won't match, causing
the memory not to be freed:
void free_defaults(char **argv)
{
MEM_ROOT ptr
memcpy_fixed((char*) &ptr,(char *) argv - sizeof(ptr), sizeof(ptr));
free_root(&ptr,MYF(0));
}
FIX: we remove load_defaults from parse_args and call it
before. Then we save argv with defaults in defaults_argv BEFORE
calling parse_args (which inside can then call handle_options
at will). Actually, found out that this is in fact kind of a
backport for BUG#38468 into 5.1, so I merged in the test case
as well and added error check for load_defaults call.
Fix based on:
revid:zhenxing.he@sun.com-20091002081840-uv26f0flw4uvo33y
Issue #3
--------
DESCRIPTION: the structure st_print_event_info constructor
would not initialize the sql_mode member, although it did for
sql_mode_inited (set to false). This would later raise the
warning in valgrind when printing the sql_mode in the event
header, as this print out is protected by a check against
sql_mode_inited and sql_mode variables. Given that sql_mode was
not initialized valgrind would output the warning.
FIX: we add initialization of sql_mode to the
st_print_event_info constructor.
client/mysqlbinlog.cc:
- Conditionally free ev->temp_buf.
- save defaults_argv before handle_options is called.
mysql-test/t/mysqlbinlog.test:
Added test case from BUG#38468.
sql/log_event.cc:
Added initialization of sql_mode for st_print_event_info.
WL#5154 was a task for formally deprecating and removing items that
were mentioned in the manual as having been deprecated since MySQL
4.1 or 5.0, but that had never been removed.
Since WL#5154 was created, examination of mysqld.cc, mysql.cc, and
mysqldump.c reveals additional deprecations not mentioned in the
manual. (In some cases, the items are simply not mentioned in the
5.1+ manuals.)
This is a follow-on task to deprecate and remove these additional
items.
The deprecation happened in MySQL 5.1, and the options/variables
are now removed from the code.
client/mysql.cc:
--no-tee is now removed
client/mysqldump.c:
--all is now removed
-a now points to --create-options
sql/mysqld.cc:
delay-key-write-for-all-tables is removed
--enable-locking is removed
--log-update is removed
--skip-locking is removed
--skip-symlink is removed
--sql-bin-update-same is removed
--warnings is removed
--record-buffer is removed
A set of program options and variables was deprecated in
MySQL 5.1, and is hereby removed.

-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:

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
