strmov() is not guaranteed to work correctly on overlapping
source and destination buffers. On some OSes it may work,
but Fedora 12 has a stpcpy() that's not working correctly
on overlapping buffers.
Fixed to use the overlap-safe version of strmov instead.
Re-vitalized the overlap-safe version of strmov.
The problem is a somewhat common misusage of the strmake function.
The strmake(dst, src, len) function writes at most /len/ bytes to
the string pointed to by src, not including the trailing null byte.
Hence, if /len/ is the exact length of the destination buffer, a
one byte buffer overflow can occur if the length of the source
string is equal to or greater than /len/.
client/mysqldump.c:
Make room for the trailing null byte.

Add comment, there is enough room in the buffer.

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).

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
transaction are not filtered out.
To fix the problem, mysqlbinlog will output 'BEGIN/ROLLBACK/COMMIT'
in regardless of the database filtering rules.
client/mysqlbinlog.cc:
Skip the database check for BEGIN/COMMIT/ROLLBACK log events.

Add my_sync.c to mysqltest sources list in CMakeLists.txt
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.

Fixed mysql_create_like_table() to call my_sync() when opt_sync_frm variable

Failing to connect would release parts of the MYSQL struct.
We would then proceed to try again to connect without re-
initializing the struct.
We prevent the unwanted freeing of data we'll still need now.
client/mysqladmin.cc:
Losing a connection (or not even getting on in the first place) should
not trash the MYSQL-struct.
Add a lot of comments.
Rewrite re-connection fu.

Assert against bad parameters usually caused by de-initing a
MYSQL-struct without re-initing it again before re-use.
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.
- Define and pass compile time path variables as pre-processor definitions to
mimic the makefile build.
- Set new CMake version and policy requirements explicitly.
- Changed DATADIR to MYSQL_DATADIR to avoid conflicting definition in
Platform SDK header ObjIdl.h which also defines DATADIR.
memory issue ?
The mysql command line client could misinterpret some character
sequences as commands under some circumstances.
The upper limit for internal readline buffer was raised to 1 GB
(the same as for server's max_allowed_packet) so that any input
line is processed by add_line() as a whole rather than in
chunks.

The --hexdump option crashed mysqlbinlog when used together
with the --read-from-remote-server option due to use of
uninitialized memory.
Since Log_event::print_header() relies on temp_buf to be
initialized when the --hexdump option is present,
dump_remote_log_entries() was fixed to setup temp_buf to point
to the start of a binlog event as done in
dump_local_log_entries().
The root cause of this bug is identical to the one for
bug #17654. The latter was fixed in 5.1 and up, so this
patch is backport of the patches for bug #17654 to 5.0.
Only 5.0 needs a changelog entry.
client/mysqlbinlog.cc:
Fixed dump_remote_log_entries() so that temp_buf is initialized
as it may be used later by Log_event::print_header() if the
--hexdump option is present.
mysql-test/r/mysqlbinlog.result:
Added a test case for bug #41943.
mysql-test/t/mysqlbinlog.test:
Added a test case for bug #41943.
When the thread executing a DDL was killed after finished its
execution but before writing the binlog event, the error code in
the binlog event could be set wrongly to ER_SERVER_SHUTDOWN or
ER_QUERY_INTERRUPTED.
This patch fixed the problem by ignoring the kill status when
constructing the event for DDL statements.
This patch also included the following changes in order to
provide the test case.
1) modified mysqltest to support variable for connection command
2) modified mysql-test-run.pl, add new variable MYSQL_SLAVE to
run mysql client against the slave mysqld.
When asking what database is selected, client expected
to *always* get an answer from the server.
We now handle failure more gracefully.
See comments in ticket for a discussion of what happens,
and how things interlock.
client/mysql.cc:
Handle empty result-sets gracefully, as opposed
to just result sets with n>0 items that may themselves
be empty.
When loading dump created by mysqldump tool an error is
thrown saying storage engine for the table doesn't have
an option.
mysqldump tries to re-insert the data into the federated
table which causes the error. Since the data is already
available on the remote server, mysqldump shouldn't try
to dump the data again for FEDERATED tables.
As stated in the bug page, it can be considered similar
to the MERGE ENGINE with "view only" nature.
Fixed by adding the "FEDERATED ENGINE" to the exception
list to ignore the data.
client/mysqldump.c:
Fixed check_if_ignore_table() to ignore FEDERATED engine
when dumping the table data.

~40Mb after mysqldump/import
When the input string exceeds the maximum allowed size for the
internal buffer, batch_readline() returns a truncated string.
Since there was no way for a caller to determine whether the
string was truncated or not, the command line client assumed
batch_readline() to always return the whole input string and
appended a newline character. This resulted in garbled data
when importing dumps containing strings longer than the
maximum input buffer size.
Fixed by adding a flag to the batch_readline() interface to
signal a truncated string to the caller.
Other minor problems fixed during patch implementation:
- The maximum allowed buffer size for batch_readline() was set
up depending on the client's max_allowed_packet value. It does
not actully make any sense, as those variables are not
related. The input buffer size limit is now always set to 1
MB.
- fill_buffer() did not always set the EOF flag.
- The input buffer could actually grow twice as the specified
limit due to insufficient checks in intern_read_line().
client/my_readline.h:
Changed the interface of batch_readline().
client/mysql.cc:
Honor the truncated flag returned by batch_readline() and do
not append the newline character if it was set. Since we can't
change the interfaces for readline()/fgets() used in the
interactive mode, always assume the returned string was not
truncated. In addition, always set the batch_readline()
internal buffer to 1 MB, independently from the client's
max_allowed_packet.
client/readline.cc:
Added the 'truncated' argument do batch_readline() to signal
truncated string to a caller.
Fixed fill_buffer() to set the EOF flag correctly.
Fixed checks in intern_read_line() to not allow the internal
buffer grow past the specified limit.
mysql-test/r/mysql.result:
Added a test case for bug #41486.
mysql-test/t/mysql.test:
