Plugins get error notifications only when my_message_sql() is called.
But errors are launched with THD::raise_condition() calls in other
places. These are push_warning(), implementations of SIGNAL and
RESIGNAL commands.
So it makes sence to notify plugins there in THD::raise_condition().
Analysis
--------
Running 'MYSQLD --help --verbose' as ROOT user without
using '--user' option displays the help contents but
aborts at the end with an exit code '1'.
While starting the server, a validation is performed to
ensure when the server is started as root user, it should
be done using '--user' option. Else we abort. In case
of help, we dump the help contents and abort.
Fix:
---
During the validation, we skip aborting the server incase
we are using the help option under the condition mentioned
above.
NOTE: Test case has not been added since it requires using
'root' user.

- Added MALLOC_LIBRARY variable to hold name of malloc library
- Back ported valgrind related fixes from jemalloc 3.4.1 to the included jemalloc 3.3.1
- Renamed bitmap_init() and bitmap_free() to my_bitmap_init() and my_bitmap_free() to avoid clash with jemalloc 3.4.1
- Use option --soname-synonyms=somalloc=NON to valgrind when using jemalloc
- Show version related variables in mysqld --help
-- Added SHOW_VALUE_IN_HELP marker
Increased back_log to 150 as the original value was a bit too small

The initialization & de-initialization of wsrep plugin is solely
controlled by wsrep_on system variable. Now, as wsrep_on is ON by
default, the plugin gets initialized during server start. However,
there would be a leakage in case wsrep_on is turned off before plugin's
deinitialization (while server is shutting down) takes place, in which
case the deinit routine will not be invoked.
In this particular case, wsrep_on is turned off as no wsrep provider
has been specified & thus the valgrind warnings.
Fixed by introducing a flag which tracks and now controls the
(de|)initialization of the wsrep plugin instead on wsrep_on.
Added necessary asserts.
main.connect [ pass ] 16534
valgrind_report [ pass ]
(thd && thd->variables.wsrep_on)) && wsrep_emulate_bin_log) ||
mysql_bin_log .is_open()' fails on SAVEPOINT with disabled
wsrep_provider
As wsrep_on system variable is ON by default the binlog handlerton
is implicitly enabled during the server initialization phase. Later,
while wsrep plugin is getting initialized, wsrep_on in corrected &
turned OFF in case wsrep provider is not specified (leaving binlog
in ON state!). This leads to the reported assertion.
Fixed by adding another check for wsrep provider before binlog
is enabled.
Added a test case.
This is now otherwise on level wsrep-25.9, but storage/innobase has not been fully merged
wsrep-5.5 is not good source for that, so we probably have to cherry pick innodb changes from wsrep-5.6
This patch fixes both the reported issues :
(1) Included '-wsrep' to the server version information.
> select @@version;
+-----------------------------+
| @@version |
+-----------------------------+
| 5.5.33a-MariaDB-wsrep-debug |
+-----------------------------+
(2) The @@version_comment would no longer have XXXX
in the wsrep version information in case cmake couldn't
determine the current bzr revision.
There were some places where insufficient locking between
parallel threads could cause invalid memory accesses and
possibly other grief.
This patch adds the missing locking, and moves the locking
into the struct rpl_binlog_state methods to make it easier
to see that proper locking is in place everywhere.
Fixed the following compilation errors and test failures:
- maria SE: "stage_waiting_for_a_resource" wasn't declared w/o PFS
- sql_repl.h: PSI_mutex_key is not available in non-PFS builds
- mysqld.cc: pfs_param is not available in non-PFS builds
- mysqld.cc: init_show_explain_psi_keys() is not available in non-PFS builds
- mysqld.cc: call net_before_header_psi, net_after_header_psi even if PFS
is not available so that thread enters stage_init at proper time. Fixes
sp-threads and a few tests in funcs_1.
- myisam_file_io.opt: added missing loose prefix

Fix: A NULL pointer was dereferenced due to which there was crash.A check was introduced
for NULL string before dereferencing it.No test cases written as it is a bug during

The merge is still missing a few hunks related to temporary tables and
InnoDB log file size. The associated code did not seem to exist in
10.0, so the merge of that needs more work. Until this is fixed, there
are a number of test failures as a result.
