If a thread is killed in the server, we throw "shutdown" only if one is actually in
progress; otherwise, we throw "query interrupted".
Control-C in the mysql command-line client is "incremental" now.
First Control-C sends KILL QUERY (when connected to 5.0+ server, otherwise, see next)
Next Control-C sends KILL CONNECTION
Next Control-C aborts client.
As the first two steps only pertain to an existing query,
Control-C will abort the client right away if no query is running.
client will give more detailed/consistent feedback on Control-C now.
client/mysql.cc:
Extends Control-C handling; enhances up feedback to user.
On 5.0+ servers, we try to be nice and send KILL QUERY first
if Control-C is pressed in the command-line client, but if
that doesn't work, we now give the user the opportunity to
send KILL CONNECTION with another Control-C (and to kill the
client with another Control-C if that somehow doesn't work
either).

There are some problems about help text:
- It is stated that "auto" is the default twice. It need be stated only once.
- It is stated that --base64-output is short for --base64-output=always. But that sounds
like the default is "always", not "auto".
Make the help text clear as following:
Determine when the output statements should be base64-encoded BINLOG
statements: 'never' disables it and works only for binlogs without
row-based events; 'auto' prints base64 only when necessary (i.e.,
for row-based events and format description events); 'always' prints
base64 whenever possible. 'always' is for debugging only and should
not be used in a production system. If this argument is not given,
the default is 'auto'; if it is given with no argument, 'always' is used.
The 'BEGIN/COMMIT/ROLLBACK' log event could be filtered out if the
database is not selected by --database option of mysqlbinlog command.
This can result in problem if there are some statements in the

To fix the problem, mysqlbinlog will output 'BEGIN/ROLLBACK/COMMIT'
in regardless of the database filtering rules.

All statements executed by mysql_upgrade are binlogged and then are replicated to slave.
This will result in some errors. The report of this bug has demonstrated some examples.
Master and slave should be upgraded separately. All statements executed by
mysql_upgrade will not be binlogged.
--write-binlog and --skip-write-binlog options are added into mysql_upgrade.
These options control whether sql statements are binlogged or not.
Option "--without-server" still not working in 5.1
The general approach is to make sure that source files
which require thread support are only compiled if the build
really needs thread support,
which means when the server is built or a thread-safe client
library.
This required several changes:
- Make sure the subdirectories "storage/" and "plugin/" are
only processed if the server is built, not ifclient-only.
- Make the compilation of some modules which inherently
require threading depend on thread supportin the build.
- Separate the handling of threading in "configure.in" from
that of server issues, threading is also needed in a
non-server build of a thread-safe client library.
Also, "libdbug" must get built even in a client-only build,
so "dbug/" must be in the list of client directories.
In addition, calls to thread functions in source files which
can be built without thread support must use the wrapper
functions which handle the non-threaded build.
So the modules "client/mysqlimport.c" and "client/mysqlslap.c"
must call "my_thread_end()" only via "mysql_thread_end()".
Makefile.am:
The directories "storage/" and "plugin/" contain files
which are needed for the server only, so their contents
is to be built only if a server is built.
They must not be named unconditionally, because building
their contents will fail unless threads are enabled.
These directories are now listed in the "configure"
variable "sql_server_dirs" which becomes part of
"sql_union_dirs" if the server is to be built.
client/mysqlimport.c:
Use the wrapper function "mysql_thread_end()" which
correctly handles the case of a non-threaded build.
client/mysqlslap.c:
Use the wrapper function "mysql_thread_end()" which
correctly handles the case of a non-threaded build.
configure.in:
Various changes to support builds "--without-server":
1) For the unit tests, we need "libdbug".
2) Separate the treatment of the server from that of the
thread-safe client library.
3) Introduce an "automake conditional" "NEED_THREAD"
which can be checked in some "Makefile.am".
4) Include "storage/" and "plugin/" in the list of
"sql_server_dirs" so that they are handled in the
top "Makefile.am" only if the server is to be built
(see the change in that file).
mysys/Makefile.am:
The code of "mf_keycache.c" in 5.1 is no longer safe
to be built without thread support.
(In 5.0, this was possible.)
Rather than fix these issues, which is tedious and risky,
avoid the need to ever build it without thread support:
It is needed in the server only, which needs thread support.
The only case where we build a "libmysys" without thread
support is for a non-threaded client, where "mf_keycache"
is not neded.
So its inclusion in the list of source files can depend
on the new conditional "NEED_THREAD".
unittest/mysys/Makefile.am:
Test program "my_atomic-t" is to verify the correct handling
of threads only, it cannot be built without thread support
and is not needed in such cases either.
Let its build depend on the new conditional "NEED_THREAD".

client/CMakeLists.txt:
BUG#46591 - .frm file isn't sync'd with sync_frm enabled
for CREATE TABLE...LIKE...
Add my_sync.c to mysqltest sources list
CREATE TABLE...LIKE...
The mysql server option 'sync_frm' is ignored when table is created with
syntax CREATE TABLE .. LIKE..
Fixed by adding the MY_SYNC flag and calling my_sync() from my_copy() when
the flag is set.
In mysql_create_table(), when the 'sync_frm' is set, MY_SYNC flag is passed
to my_copy().
Note: TestCase is not attached and can be tested manually using debugger.

with gcc 4.3.2
This patch fixes a number of GCC warnings about variables used
before initialized. A new macro UNINIT_VAR() is introduced for
use in the variable declaration, and LINT_INIT() usage will be
gradually deprecated. (A workaround is used for g++, pending a
patch for a g++ bug.)
GCC warnings for unused results (attribute warn_unused_result)
for a number of system calls (present at least in later
Ubuntus, where the usual void cast trick doesn't work) are
also fixed.
client/mysqlmanager-pwgen.c:
A fix for warn_unused_result, adding fallback to use of
srand()/rand() if /dev/random cannot be used. Also actually
adds calls to rand() in the second branch so that it actually
creates a random password.

when used with --tab
1) New syntax: added CHARACTER SET clause to the
SELECT ... INTO OUTFILE (to complement the same clause in
LOAD DATA INFILE).
mysqldump is updated to use this in --tab mode.
2) ESCAPED BY/ENCLOSED BY field parameters are documented as
accepting CHAR argument, however SELECT .. INTO OUTFILE
silently ignored rests of multisymbol arguments.
For the symmetrical behavior with LOAD DATA INFILE the
server has been modified to fail with the same error:
ERROR 42000: Field separator argument is not what is
expected; check the manual
3) Current LOAD DATA INFILE recognizes field/line separators
"as is" without converting from client charset to data
file charset. So, it is supposed, that input file of
LOAD DATA INFILE consists of data in one charset and
separators in other charset. For the compatibility with
that [buggy] behaviour SELECT INTO OUTFILE implementation
has been saved "as is" too, but the new warning message
has been added:
Non-ASCII separator arguments are not fully supported
This message warns on field/line separators that contain
non-ASCII symbols.
client/mysqldump.c:
mysqldump has been updated to call SELECT ... INTO OUTFILE
statement with a charset from the --default-charset command
line parameter.

2) warn with a new WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED
message on non-ASCII field or line separators.
The select_export::send_data() merhod has been modified to
convert item data to output charset (see new SELECT INTO OUTFILE
syntax). By default the BINARY charset is used for backward
compatibility.
sql/sql_class.h:
The select_export::write_cs field added to keep output
charset.

(common code has been moved from check_string_copy_error()).
sql/sql_string.h:
New String::is_ascii() method and new global convert_to_printable()
function have been added.
sql/sql_yacc.yy:
New syntax: added CHARACTER SET clause to the
SELECT ... INTO OUTFILE (to complement the same clause in
LOAD DATA INFILE). By default the BINARY charset is used for
backward compatibility.
unnecessarily
The problem is that libmysqlclient.so is built with THREAD
undefined, while a client compiling against the same header
files will see THREAD as defined and definitions in
my_pthread.h will be included, possibly resulting in undefined
symbols that cannot be resolved with libmysqlclient.so.
The suggested solution is to require that clients wanting to
link with libmysqlclient.so should be built with
MYSQL_CLIENT_NO_THREADS defined. This requires a documentation
change, and more details for this will be supplied if this
patch is approved.
The MYSQL_CLIENT_NO_THREADS define was renamed from
UNDEF_THREADS_HACK, to get a more suitable (less suspicious)
name for the define. (The UNDEF_THREADS_HACK is retained for
backwards compatibility, though.)
This patch is also in anticipation of WL#4958, which will
remove this problem altogether by dropping the building of
libmysqlclient.
server
If the server connection was lost during repeated status commands,
the client would fail to detect this and the client output would be inconsistent.
This patch fixes this issue by making sure that the server is online
before the client attempts to execute the status command.
client/mysql.cc:
* Replace variable "connected" with a call to mysql_real_query_for_lazy()

mysqlbinlog --database parameter was being ignored when processing
row events. As such no event filtering would take place.
This patch addresses this by deploying a call to shall_skip_database
when table_map_events are handled (as these contain also the name of
the database). All other rows events referencing the table id for the
filtered map event, will also be skipped.
client/mysqlbinlog.cc:
Added shall_skip_database call to the part of the code that handles
Table_map_log_events. It inspects the database name and decides whether
to filter the event or not. Furthermore, if table map event is filtered
next events referencing the table id in the table map event, will also
be filtered.
mysql-test/suite/binlog/t/binlog_row_mysqlbinlog_db_filter.test:
Test case that checks if row events are actually filtered out.
