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.
sql/log_event.h:
Added a map for holding the currently ignored table map events.
Table map events are inserted when they shall be skipped and removed
once the last row event in the statement is processed.
uninitialized variable used as subscript

Bug #44886: SIGSEGV in test_if_skip_sort_order() -
uninitialized variable used as subscript
1. The test_if_order_by_key function returned unitialized
used_key_parts parameter in case of a "constant" InnoDB
table. Calling function uses this parameter values as
an array index, thus sometimes it caused a crash.
The test_if_order_by_key function has been modified
to set used_key_parts to 0 (no need for ordering).
2. The test_if_skip_sort_order function has been
modified to accept zero used_key_parts value and
to prevent an array access by negative index.
The problem is that when a optimization of read-only transactions
(bypass 2-phase commit) was implemented, it removed the code that
reseted the XID once a transaction wasn't active anymore:
sql/sql_parse.cc:
- bzero(&thd->transaction.stmt, sizeof(thd->transaction.stmt));
- if (!thd->active_transaction())
- thd->transaction.xid_state.xid.null();
+ thd->transaction.stmt.reset();
This mostly worked fine as the transaction commit and rollback
functions (in handler.cc) reset the XID once the transaction is
ended. But those functions wouldn't reset the XID in case of
a empty transaction, leading to a assertion when a new starting
a new XA transaction.
The solution is to ensure that the XID state is reset when empty
transactions are ended (by either commit or rollback). This is
achieved by reorganizing the code so that the transaction cleanup
routine is invoked whenever a transaction is ended.

Problem:
Crash happened with a user-defined utf8 collation,
on attempt to insert a value longer than the column
to store.
Reason:
The "ctype" member was not initialized (NULL) when
allocating a user-defined utf8 collation, so an attempt
to call my_ctype(cs, *str) to check if we loose any important
data when truncating the value made the server crash.
Fix:
Initializing tge "ctype" member to a proper value.

The server was not cleaning the last IO error and error number when
resetting slave.
This patch addresses this issue by backporting into 5.1 part of the
patch in BUG 34654. A fix for this issue had already been pushed into
6.0 as part of the aforementioned bug, however the patch also included
some refactoring. The fix for 5.1 does not take into account the
refactoring part.
mysql-test/extra/rpl_tests/rpl_reset_slave.test:
Backported the test case and improved with deploying include/start_slave.inc
in relevant spots.
sql/slave.cc:
Backported part of patch from 6.0 that includes cleaning
mi->clear_error() at:
1. beginning of handle_slave_io
2. on successful connection
Also, backported the assertion added in the original patch.
sql/sql_repl.cc:
Backported the call to mi->clear_error() on reset_slave().
The crash happens due to wrong max_length value which is set on
Item_func_round::fix_length_and_dec() stage. The value is set to
args[0]->max_length which is too big in case of LONGTEXT(LONGBLOB) fields.
The fix is to set max_length using float_length() function.

BEGIN/COMMIT/ROLLBACK was subject to replication db rules, and
caused the boundary of a transaction not recognized correctly
when these queries were ignored by the rules.
Fixed the problem by skipping replication db rules for these
statements.

MySQL crashes if a user without proper privileges attempts to create a procedure.
The crash happens because more than one error state is pushed onto the Diagnostic
area. In this particular case the user is denied to implicitly create a new user
account with the implicitly granted privileges ALTER- and EXECUTE ROUTINE.
The new account is needed if the original user account contained a host mask.
A user account with a host mask is a distinct user account in this context.
An alternative would be to first get the most permissive user account which
include the current user connection and then assign privileges to that
account. This behavior change is considered out of scope for this bug patch.
The implicit assignment of privileges when a user creates a stored routine is a
considered to be a feature for user convenience and as such it is not
a critical operation. Any failure to complete this operation is thus considered
non-fatal (an error becomes a warning).
The patch back ports a stack implementation of the internal error handler interface.
This enables the use of multiple error handlers so that it is possible to intercept
and cancel errors thrown by lower layers. This is needed as a error handler already
is used in the call stack emitting the errors which needs to be converted.

* Moved my_ok() signal from mysql_routine_grant to make it easier to avoid

so that if "CREATE PROCEDURE" fails because "Password hash isn't a hexidecimal
number" it is still clear what happened.

mysqldump --tab still dumped triggers to stdout rather than to
individual tables.
We now append triggers to the .sql file for the corresponding

old_password() functions
The PASSWORD() and OLD_PASSWORD() functions could lead to
memory reads outside of an internal buffer when used with BLOB
arguments.
String::c_ptr() assumes there is at least one extra byte
in the internally allocated buffer when adding the trailing
'\0'. This, however, may not be the case when a String object
was initialized with externally allocated buffer.
The bug was fixed by adding an additional "length" argument to
make_scrambled_password_323() and make_scrambled_password() in
order to avoid String::c_ptr() calls for
PASSWORD()/OLD_PASSWORD().
However, since the make_scrambled_password[_323] functions are
a part of the client library ABI, the functions with the new
interfaces were implemented with the 'my_' prefix in their
names, with the old functions changed to be wrappers around
the new ones to maintain interface compatibility.
