e.g.MYSQL_AUDIT_GENERAL_ERROR
General audit API (MYSQL_AUDIT_GENERAL_CLASS) didn't expose event
subclass to plugins.
This patch exposes event subclass to plugins via
struct mysql_event_general::event_subclass.
This change is not compatible with existing general audit plugins.
Audit interface major version has been incremented.
include/mysql/plugin_audit.h:
Expose event subclass to audit general plugins.
plugin/audit_null/audit_null.c:
Added distinct counters for general event sub-classes.
Removed printf() from deinit(). One can easily see number of
calls via status variables.
To make code nicer, modified class mask to use macro instead
of hardcoded number.
Incremented audit plugin minor version.
sql/sql_audit.cc:
Expose event subclass to audit general plugins.
to cleanup open connections
It was possible to UNINSTALL storage engine plugin when binding
between THD object and storage engine is still active (e.g. in
the middle of transaction).
To avoid unclean deactivation (uninstall) of storage engine plugin
in the middle of transaction, additional storage engine plugin
lock is acquired by thd_set_ha_data().
If ha_data is not null and storage engine plugin was not locked
by thd_set_ha_data() in this connection before, storage engine
plugin gets locked.
If ha_data is null and storage engine plugin was locked by
thd_set_ha_data() in this connection before, storage engine
plugin lock gets released.
If handlerton::close_connection() didn't reset ha_data, server does
it immediately after calling handlerton::close_connection().
Note that this is just a framework fix, storage engines must switch
to thd_set_ha_data() from thd_ha_data() if they want to see fit.
include/mysql/plugin.h:
As thd_{get|set}_ha_data() have some extra logic now, they
must be implemented on server side.
include/mysql/plugin.h.pp:
As thd_{get|set}_ha_data() have some extra logic now, they
must be implemented on server side.
sql/handler.cc:
Make sure ha_data is reset and ha_data lock is released.
sql/handler.h:
hton is not supposed to be updated by ha_lock_engine(),
make it const.
sql/sql_class.cc:
As thd_{get|set}_ha_data() have some extra logic now, they
must be implemented on server side.
sql/sql_class.h:
Added ha_data lock.

Bug#13174: SHA2 function
Patch contributed from Bill Karwin, paper unnumbered CLA in Seattle
Implement SHA2 functions.
Chad added code to make it work with YaSSL. Also, he removed the
(probable) bug of embedded server never using SSL-dependent
functions. (libmysqld/Makefile.am didn't read ANY autoconf defs.)
Function specification:
SHA2( string cleartext, integer hash_length )
-> string hash, or NULL
where hash_length is one of 224, 256, 384, or 512. If either is
NULL or a length is unsupported, then the result is NULL. The
resulting string is always the length of the hash_length parameter
or is NULL.
Include the canonical hash examples from the NIST in the test
results.

Several problems addressed:
1. The maximum value for --open_files_limit on non-windows boxes
is now raised to UINT_MAX (the maximum possible without significant
changes in the code). The maximum value on windows is kept to be
2048 due to a known limitation (bug 24509).
2. mysqld_safe now supports --open_files_limit=xx in addition to
--open-files-limit=xx
3. mysqld_safe always passes through --open[_-]files[_-]limit
to the underlying mysqld. It used to pass it through only if it
the user running the script has access to the root directory or
there was an --user argument specified.
4. Fixed a prototype in my_file.c to match its counterpart in
the other #ifdef branch.
This patch:
- Moves all definitions from the mysql_priv.h file into
header files for the component where the variable is
defined
- Creates header files if the component lacks one
- Eliminates all include directives from mysql_priv.h
- Eliminates all circular include cycles
- Rename time.cc to sql_time.cc
- Rename mysql_priv.h to sql_priv.h

This is a fix specific for HPUX,
for which the compiler does not resolve properly dependencies
involving unused inline functions.
(See existing comments in mysql_thread.h)
In include/mysql/psi/mysql_thread.h,
the instrumentation helpers for mysql_prlock_*
uses the pr lock apis.
These apis are implemented in mysys/thr_rwlock.c,
which is not linked to client code.
As a result, the code does not link in libmysql_r, on HPUX.
The fix is to cut dependencies explicitely,
by introducing -DDISABLE_MYSQL_RWLOCK_H,
when building client code.
Before this fix, the performance schema instrumentation
in mdl.h / mdl.cc was incomplete, causing:
- build warnings,
- no data collection for the performance schema
This fix:
- added instrumentation helpers for the new preferred
reader read write lock, mysql_prlock_*
- implemented completely the performance schema
instrumentation of mdl.h / mdl.cc

On platforms where read-write lock implementation does not
prefer readers by default (Windows, Solaris) server might
have deadlocked while detecting MDL deadlock.
MDL deadlock detector relies on the fact that read-write
locks which are used in its implementation prefer readers
(see new comment for MDL_lock::m_rwlock for details).
So far MDL code assumed that default implementation of
read/write locks for the system has this property.
Indeed, this turned out ot be wrong, for example, for
Windows or Solaris. Thus MDL deadlock detector might have
deadlocked on these systems.
This fix simply adds portable implementation of read/write
lock which prefer readers and changes MDL code to use this
new type of synchronization primitive.
No test case is added as existing rqg_mdl_stability test can
serve as one.

Extended existing my_rw_lock_t implementation to support

Use portable read-write locks which prefer readers instead of
relying on that system implementation of read-write locks has
this property (this was true for Linux/NPTL but was false,
for example, for Windows and Solaris).
Added comment explaining why preferring readers is important
for MDL deadlock detector (thanks to Serg for example!).
sql/mdl.h:
Use portable read-write locks which prefer readers instead of

for example, for Windows and Solaris).
A client doing multiple mysql_library_init() and
mysql_library_end() calls over the lifetime of the process may
experience lost character set data, potentially even a
SIGSEGV.
This patch reinstates the reloading of character set data when
a mysql_library_init() is done after a mysql_library_end().
Two problems addressed here:
Embedded-server linking failure.
sql/sys_vars.cc absents in the libmysqld/CMakeLists.txt
The PERFORMANCE_SCHEMA-related failure of the embedded-server compilation.
We try to disable the PERFORMANCE_SCHEMA in the embedded server
as it's considered useless there. But we do it in wrong way as
we only disable header's links to the PF, not the PF's library itself.
So on Unix-ex the embedded library still contains the PF code and
grows bigger with no reason. On Windows that just fails to compile.
per-file comments:
include/my_global.h
Bug#41103 6.0 Windows embedded-server tests fail
No PERFORMANCE_SCHEMA disabling in the embedded server. User can
just use the --without-perfschema-engine-plugin option to exclude it
from the compilation.

The task is to

(b) increase the maximum length of column, table and the new index comments.
The patch committed on behalf of Yoshinori Matsunobu (Yoshinori.Matsunobu@Sun.COM).
This patch removes the unused server variable
"table_lock_wait_timeout".
mysql-test/r/variables.result:
Updated the test for Bug#28580 to reflect that
"table_lock_wait_timeout" no longer exists.
mysql-test/t/variables.test:
Updated the test for Bug#28580 to reflect that
"table_lock_wait_timeout" no longer exists.
This patch introduces timeouts for metadata locks.
The timeout is specified in seconds using the new dynamic system
variable "lock_wait_timeout" which has both GLOBAL and SESSION
scopes. Allowed values range from 1 to 31536000 seconds (= 1 year).
The default value is 1 year.
The new server parameter "lock-wait-timeout" can be used to set
the default value parameter upon server startup.
"lock_wait_timeout" applies to all statements that use metadata locks.
These include DML and DDL operations on tables, views, stored procedures
and stored functions. They also include LOCK TABLES, FLUSH TABLES WITH
READ LOCK and HANDLER statements.
The patch also changes thr_lock.c code (table data locks used by MyISAM
and other simplistic engines) to use the same system variable.
InnoDB row locks are unaffected.
One exception to the handling of the "lock_wait_timeout" variable
is delayed inserts. All delayed inserts are executed with a timeout
of 1 year regardless of the setting for the global variable. As the
connection issuing the delayed insert gets no notification of
delayed insert timeouts, we want to avoid unnecessary timeouts.
It's important to note that the timeout value is used for each lock
acquired and that one statement can take more than one lock.
A statement can therefore block for longer than the lock_wait_timeout
value before reporting a timeout error. When lock timeout occurs,
ER_LOCK_WAIT_TIMEOUT is reported.
Test case added to lock_multi.test.
