There is failure on pushbuild machines which are using old compilers complaining about
ULLONG_MAX declaration. Changing this to ULONGLONG_MAX to solve the problem.

  Change ULLONG_MAX to ULONGLONG_MAX for the max_binlog_cache_size option

Problem was that InnoDB used filenam_to_tablename,
which do not handle partitions (due to the '#' in
the filename).

Solution is to add a new function for explaining
what the filename means: explain_filename.
It expands the database, table, partition and subpartition
parts and uses errmsg.txt for localization.
It also converts from my_charset_filename to system_charset_info
(i.e. human readable form for non ascii characters).

It has three different output styles.

NOTE: This is the server side ONLY part (introducing the explain_filename
function). There will be a patch for InnoDB using this function to solve
the bug.

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.

Running a SELECT query over an IBMDB2I table with a cp1250 character set
was producing an error 2027 (ibmdb2i error 2027: Error converting single-byte
sort sequence to UCS-2).

The QMY_DESCRIBE_RANGE API was returning error 2027 to the storage engine
because the CCSID used for a cp1250 column (870) does not match the CCSID
used by the DB2 sort sequences associated with cp1250_* collations (1153).
This was because the storage engine relies on a set of system APIs to
determine which CCSID value most closely matches a particular MySQL
character set. However, in the case of cp1250, the system is returning
CCSID 870, which does not have a codepoint for the euro symbol, making it
an incorrect match.

This patch overrides the selection of a compatible CCSID to always return
1153 for cp1250.

  Bug#45197 cp1250 character set with IBMDB2I generates 2027 error

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.

  Skip checking replication db rules for BEGIN/COMMIT/ROLLBACK statements

Bug#34309: '_PC' macro redefinition

For reasons that are now a mystery, we had defined a CPP symbol to
help ancient compilers work better (in some way that's lost to history).
This interferes with at least one modern compiler.

Now, don't define the _PC symbol.  Those other underscore-leading
symbols are suspect also, but at least the names aren't inscrutable.
Let's leave them for now.

Make the caller of Query_log_event, Execute_load_log_event
constructors and THD::binlog_query to provide the error code
instead of having the constructors to figure out the error code.

sql/log_event.cc:
  Changed constructors of Query_log_event and Execute_load_log_event to accept the error code argument instead of figuring it out by itself
sql/log_event.h:
  Changed constructors of Query_log_event and Execute_load_log_event to accept the error code argument

When doing ALTER TABLE, we forgot to point out that we actually have
ROW_FORMAT information (from the original table), so we dropped to
"sensible defaults". This affects both ALTER TABLE and OPTIMIZE TABLE
which may fall back on ALTER TABLE for InnoDB.

We now flag that we do indeed know the row-type, thereby preserving
compression-type etc.

No .test in 5.1 since we'd need a reasonable new plugin from InnoDB to
show this properly; in higher versions, maria can demonstrate this.

sql/sql_table.cc:
  In mysql_alter_table() flag that we have row-type info
  from old table. In compare_tables(), we must explicitly
  check whether row-type has changed (rather than rely on
  the flag which will always be set at this point now).

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.

wmemset was being used to fill the row buffers.
wmemset was intended  to  fill the buffer with
16-bit UCS2 pad values.  However,  the  64-bit
version of wmemset uses 32-bit wide characters
and thus filled the buffer incorrectly. In some
cases, the null  byte  map would be overwritten,
causing ctype_utf8.test and ibmdb2i_rir.test to
fail, giving the error message CPF5035.

This patch eliminates the use of wmemset to fill
the row buffer. wmemset has  been  replaced with
memset16, which always  fills  memory with 16-bit
values.
