Fixed compilation problem on windows.
configure.cmake:
Added test for pthread_attr_getguardsize
include/my_stacktrace.h:
Define dummy my_init_stacktrace() to allow one to call it without #ifdef HAVE_STACKTRACE
sql/mysqld.cc:
Move my_setstacksize() to fix compilation problem on windows
Don't disable core on signal just becasue platform doesn't handle stack trace
mysql-test/suite/innodb/t/group_commit_crash.test:
remove autoincrement to avoid rbr being used for insert ... select
mysql-test/suite/innodb/t/group_commit_crash_no_optimize_thread.test:
remove autoincrement to avoid rbr being used for insert ... select
mysys/my_addr_resolve.c:
a pointer to a buffer is returned to the caller -> the buffer cannot be on the stack
mysys/stacktrace.c:
my_vsnprintf() is ok here, in 5.5
include/mysql_com.h:
remove "shutdown levels" that aren't shutdown levels from mysql_enum_shutdown_level
mysys/my_addr_resolve.c:
my_snprintf in 5.5 (but not in 5.3) supports %p
sql/item_func.cc:
use a method (that exists only in 5.5) instead of directly accessing a member
sql/item_subselect.cc:
use a method (that exists only in 5.5) instead of directly accessing a member
sql/opt_subselect.cc:
use a method (that exists only in 5.5) instead of directly accessing a member
sql/sql_select.cc:
use a method (that exists only in 5.5) instead of directly accessing a member
modified for MySQL 5.5. Logger service moved to the
plugin/sql_errlog directory to be properly used later.
plugin/sql_errlog/sql_errlog.c:
Fixes for bugs #956427 (SQL_ERROR_LOG plugin produces bogus warnings about sql-error-log-size-limit value) and #956463 (Server crashes if SQL_ERROR_LOG fails to initialize) they're also MDEV-184 and MDEV-183
The sql_error_log_deinit() should be prepared for the logger_file to be NULL.
The logger_file_size_limit upper limit wasn't properly set.
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
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
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.

Fixed README with link to source
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.
