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.
mysql-client used static buffer to concatenate server-
version and version_comment. Sufficiently long comments
could get cut off. This was harmless, but looked daft.
Now using a dynamic buffer instead.
client/mysql.cc:
Use dynamic rather than static buffer for server
information. If we can get both version and comment,
concat them and use that. Otherwise, try to use just
version. If that fails too, return empty string so
overly trusting callers do not crash. Release memory
as needed.
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.

Added a test case for bug #41486.
mysql-test/t/mysql.test:
Added a test case for bug #41486.
--ignore-table option
mysqldump would correctly omit temporary tables for views, but would
incorrectly still emit all CREATE VIEW statements.
Backport a fix from 5.1, where we capture the names we want to emit
views for in one pass (the placeholder tables) and in the pass where
we actually emit the views, we don't emit a view if it wasn't in that
list.
Took the Xfree implementation (based on the same rewrite as the NDB one)
and added it instead of the current implementation.
Added a macro to make the calls to MD5 more streamlined.

There was a problem when a DELIMITER COMMAND is not the first
command on the line. I this case an extra line feed was added
to the glob buffer and this was causing subsequent attempts
to enter this delimiter to fail.
Fixed by not adding a new line to the glob buffer if the
command being added is a DELIMITER

mysqldump included character_set_client magic
that is unknown before 4.1 even when asked for
an appropriate compatibility mode.
In compatibility (3.23, 4.0) mode, we do not
output charset statements (not even in a
"comment conditional"), nor do we do magic on
the server, even if the server is sufficient
new (4.1+). Table-names will be output converted
to the charset requested by mysqldump; if such
a conversion is not possible (Ivrit -> Latin),
mysqldump will fail.
Typo existed in help-text for command "charset" in mysql
client, making the parameter-name different for long and
short forms of the command for no good reason.
Fixed.
client/mysql.cc:
Make parameter-name in help-text the same for
long and short forms, for consistency.
- Remove bothersome warning messages. This change focuses on the warnings
that are covered by the ignore file: support-files/compiler_warnings.supp.
- Strings are guaranteed to be max uint in length
