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.

mysql.procs_priv table itself does not get replicated.
Inserting routine privilege record into mysql.procs_priv table
is triggered by creating function/procedure statements
according to current user's privileges.
Because the current user of SQL thread has GLOBAL_ACL,
which doesn't need any check mysql.procs_priv privilege
when create/alter/execute routines.
Corresponding GLOBAL_ACL privilege user
doesn't insert routine privilege record into
mysql.procs_priv when creating a routine.
Fixed by switching the current user of SQL thread to definer user if
the definer user exists on slave.
That populates procs_priv, otherwise to keep the SQL thread
user and procs_priv remains unchanged.

Compiling with debug and assigning an invalid directory to --slave-load-tmpdir
was crashing the slave due to the following assertion DBUG_ASSERT(! is_set() ||
can_overwrite_status). This assertion assumes that a thread can change its
state once (i.e. ok,error, etc) before aborting, cleaning/resuming or completing
its execution unless the overwrite flag (i.e. can_overwrite_status) is true.
The Append_block_log_event::do_apply_event which is responsible for creating
temporary file(s) was not cleaning the thread state. Thus a failure while
trying to create a file in an invalid temporary directory was causing the crash.
To fix the problem we check if the temporary directory is valid before starting
the SQL Thread and reset the thread state before creating a file in
Append_block_log_event::do_apply_event.
~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.

Any statement reading corrupt archive data file
(CHECK/REPAIR/SELECT/UPDATE/DELETE) may cause assertion
failure in debug builds. This assertion has been removed
and an error is returned instead.
Also fixed that CHECK/REPAIR returns vague error message
when it mets corruption in archive data file. This is
fixed by returning proper error code.

"Release_lock("hello")" is now also successful when delivering NULL, replaced two sleeps by wait_condition. The last two "sleep 1" have not been replaced as all tried wait conditions leaded to nondeterministic results, especially to succeeding concurrent updates. To replace the sleeps there should be some time planned (or internal knowledge of the server may help).
If a sys-var has a base and a block-size>1, and then a
user-supplied value >= minimum ended up below minimum
thanks to block-size alignment, we threw a warning.
This meant for instance that when getting, then setting
the minimum, we'd see a warning. This was needlessly
confusing. (updated patch)
The problem is issued because we set wrong start position and stop position of query string into binlog.
That two values are stored as part of head info of query string.
When we parse binlog, we first get position values then get the query string according position values.
But seems that two values are not calculated correctly after the parse of Yacc.
We don't want to touch so much of yacc because it may influence other codes.
So just add one space after 'INTO' key word when parsing.
This can easily resolve the problem.

predicates.

Revised patch incorporating cleaner test code brought up during review.
Removed the use of grep and accomplished same actions via SQL / use of the server.
Runs as before on *nix systems and now runs on Windows without Cygwin as well.
