Added the logger service that provides us with the rotating logs.
The plugin SQL_ERROR_LOG added. It logs the errors using the 'logger service'
for the rotating log files.
the example record from the log:
2012-03-09 15:07:29 root[root] @ localhost [] ERROR 1146: Table 'test.xyz' doesn't exist : select * from test.xyz
There are two threads. In one thread, dml operation is going on
involving cascaded update operation. In another thread, alter
table add foreign key constraint is happening. Under these
circumstances, it is possible for the dml thread to access a
dict_foreign_t object that has been freed by the ddl thread.
The debug sync test case provides the sequence of operations.
Without fix, the test case will crash the server (because of
newly added assert). With fix, the alter table stmt will return
an error message.
Backporting the fix from MySQL 5.5 to 5.1

Fixed wrong mutex order bug in Aria when flush_log_for_bitmap() was called when table is not yet marked for change.
include/my_base.h:
Added flag that table is opened only for status
mysql-test/r/myisam-big.result:
Test case for lp:925377
mysql-test/t/myisam-big.test:
Test case for lp:925377
sql/sql_base.cc:
If thd->version == 0 (happens only when we are opening a table that is flushed under MYSQL_LOCK_IGNORE_FLUSH), open the table in HA_OPEN_FOR_STATUS mode
storage/maria/ma_bitmap.c:
Fixed wrong mutex order bug in Aria when flush_log_for_bitmap() was called when table is not yet marked for change.
storage/maria/ma_dbug.c:
Ignore last_version <= 1 as these are either flushed or only opened for status
storage/maria/ma_open.c:
Use last_version=1 as a marker that table was opened with HA_OPEN_FOR_STATUS.
In this case we just open a new version of the table in read only mode.
storage/myisam/mi_create.c:
Update prototype
storage/myisam/mi_dbug.c:
Ignore last_version <= 1 as these are either flushed or only opened for status
storage/myisam/mi_open.c:
Use last_version=1 as a marker that table was opened with HA_OPEN_FOR_STATUS.
If HA_OPEN_FOR_STATUS is used, we will not assert if there is an old not-to-be-used version of the table existing.
In this case we just open a new version of the table in read only mode.
storage/myisam/myisamdef.h:
Updated prototype

Merged InnoDB change to XtraDB
README:
Added information of where to find MariaDB code
storage/archive/ha_archive.cc:
Removed memset() of rows, a MariaDB checksum's doesn't touch not used data.
On shutdown(), Windows can drop traffic still queued for sending even if that
wasn't specifically requested. As a result, fatal errors (those after
signaling which the server will drop the connection) were sometimes only
seen as "connection lost" on the client side, because the server-side
shutdown() erraneously discarded the correct error message before sending
it.
If on Windows, we now use the Windows API to access the (non-broken) equivalent
of shutdown().
Backport from trunk

Backport from trunk
include/violite.h:
export mysql_socket_shutdown(). It lives in vio in the backport.
sql/mysqld.cc:
Go through our own shutdown() rather than straight to the POSIX one.
vio/viosocket.c:
Define mysql_socket_shutdown(). On UNIXoid systems, it's just a wrapper for shutdown(), but
on Window, it uses DisconnectEx, which is magic.
The error is due to conflict between min/max macros in my_global.h
and system header < limits>, indirectly included via generated
probes_mysql_dtrace.h
Temporarily undefined min/max for the inclusion of the probes_mysq_dtrace.h
Fix memory leak in one error case in mysqldump.
Fix that HAVE_VALGRIND_VALGRIND_H is now HAVE_VALGRIND in 5.5.
Fix that @have_ssl should not be set in embedded (introduced when
removing #undef HAVE_OPENSSL from my_global.h).
VIO has SSL in embedded server anyway, so we do not win anything by excluding it.
This was actually already done in this changeset:
revision-id: kostja@sun.com-20100413150445-8x23keoxdiufgq76
"... Also, he removed the (probable) bug of embedded server never using SSL-dependent functions..."
But was apparenly lost by a mis-merge of WL#5030.
ON 64 BIT MACHINES
PROBLEM: When sorting index during repair of
myisam tables, due to improper casting
of buffer size variables value of myisam_
sort_buffer_size is not set greater than
4GB.
SOLUTION: Proper casting of buffer size variable.
myisam_buffer_size changed to unsigned
long long to handle size > 4GB on
linux as well as windows.
Introducing new collations:
utf8_general_mysql500_ci and ucs2_general_mysql500_ci,
to reproduce behaviour of utf8_general_ci and ucs2_general_ci
from mysql-5.1.23 (and earlier).
The collations are added to simplify upgrade from mysql-5.1.23 and earlier.
Note: The patch does not make new server start over old data automatically.
Some manual upgrade procedures are assumed.
Paul: please get in touch with me to discuss upgrade procedures
when documenting this bug.

- Do not compile files that are not needed on Windows (my_addr_resolve, an
d safemalloc related stuff it it is not used)
Avoids linker warnings about compilation of essentially empty files.
to work around the lack of a bzero() prototype.
include/m_string.h:
AIX does have bzero() in its system libraries,
and the configure phase detects it, including the prototype
(sets both HAVE_BZERO and HAVE_DECL_BZERO),
but the declaration is missing when the source is compiled.
Several attempts all failed.
This patch takes the brute force approach to always map
"bzero()" to "memset()" on AIX,
like is done on platforms where "bzero()" is not found at all.
and cryptic error 1126 message
The problem was that dlopen() related code was using just a subset
of the path normalization routines used in other places.
Fixed the expansion of the pre-dlopen() behavior for plugins and UDFs
to use a platform-dependent consistent encoding of the paths.
Fixed the error dlopen() error handling to take the correct error message
and strip off the trailing newline character(s).
Fixed tests to do a platform independent replace of directories and to
account for the traling slash.
Main change is that non-blocking operation is now an option that must be
explicitly enabled with mysql_option(mysql, MYSQL_OPT_NONBLOCK, ...)
before any non-blocing operation can be used.
Also the CLIENT_REMEMBER_OPTIONS flag is now always enabled and thus
effectively ignored (it was not really useful anyway, and this simplifies
things when non-blocking mysql_real_connect() fails).
