This is the non-ndb part of the patch.
The return value of mysql_bin_log.write was ignored by most callers,
which may lead to inconsistent on master and slave if the transaction
was committed while the binlog was not correctly written. If
my_error() is call in mysql_bin_log.write, this could also lead to
assertion issue if my_ok() or my_error() is called after.
This fixed the problem by let the caller to check and handle the
return value of mysql_bin_log.write. This patch only adresses the
simple cases.

Non-transactional updates that take place inside a transaction present problems
for logging because they are visible to other clients before the transaction
is committed, and they are not rolled back even if the transaction is rolled
back. It is not always possible to log correctly in statement format when both
transactional and non-transactional tables are used in the same transaction.
In the current patch, we ensure that such scenario is completely safe under the
ROW and MIXED modes.
Backport for 5.5
In non debug builds, the statements:
- SHOW PROCEDURE CODE
- SHOW FUNCTION CODE
used to fail with a "syntax error", which is misleading.
These statements have been changed to return the following error for non
debug builds:
ERROR HY000: The 'SHOW PROCEDURE|FUNCTION CODE' feature is disabled; you
need MySQL built with '--with-debug' to have it working
For debug builds (./configure --with-debug), nothing is changed.
BUG#47983: rpl_extraColmaster_myisam failed in PB2 with "Found
warnings!!"
BUG 45214 fixed the case when get_master_version_and_clock
function, used by the slave, would not report errors. The slave
now detects them and if related to transient network failures, it
prints some warnings and retries to connect. On the other hand,
if not network related, it just gives up and fails.
As such, sometimes, in PB2, the slave comes across some transient
communication issues between master and slave, while calling
get_master_version_and_clock, causing warnings print outs to the
error log. Nevertheless, in such cases slave retries to connect,
in which it succeeds, and the test case continues as it normally
would. But then, at the end of a successful test run, MTR checks
the error log, finds the unexpected warnings and considers them
harmful. This causes MTR to report error and, consequently, PB2
to report a failing test.
We fix this by adding to the global warnings suppress list the
warnings related to transient network failures only, which are
reported while in function get_master_version_and_clock.
Problem 1:
column_priv_hash uses utf8_general_ci collation
for the key comparison. The key consists of user name,
db name and table name. Thus user with privileges on table t1
is able to perform the same operation on T1
(the similar situation with user name & db name, see acl_cache).
So collation which is used for column_priv_hash and acl_cache
should be case sensitive.
The fix:
replace system_charset_info with my_charset_utf8_bin for
column_priv_hash and acl_cache
Problem 2:
The same situation with proc_priv_hash, func_priv_hash,
the only difference is that Routine name is case insensitive.
So the fix is to use my_charset_utf8_bin for
proc_priv_hash & func_priv_hash and convert routine name into lower
case before writing the element into the hash and
before looking up the key.
Additional fix: mysql.procs_priv Routine_name field collation
is changed to utf8_general_ci.
It's necessary for REVOKE command
(to find a field by routine hash element values).
Note:
It's safe for lower-case-table-names mode too because
db name & table name are converted into lower case
(see GRANT_NAME::GRANT_NAME).

Patch for Bug#38347: ALTER ROUTINE privilege allows SHOW CREATE TABLE.
If a user has any of the following privileges for a table (or the database
if the table), he should be able to issue SHOW CREATE TABLE for the table:
- CREATE
- DROP
- ALTER
- DELETE
- INDEX
- INSERT
- SELECT
- UPDATE
- TRIGGER
- REFERENCES
- GRANT OPTION
- CREATE VIEW
- SHOW VIEW
Any other privilege (even SUPER) should not allow SHOW CREATE TABLE.

message:
Additional patch for Bug#38347 (ALTER ROUTINE privilege
allows SHOW CREATE TABLE).
The problem was that information_schema.test,
information_schema_parameters.test and information_schema_routines.test
failed with the first patch. That happened due to limitation in check_access():
it allows only SELECT_ACL privilege for INFORMATION_SCHEMA tables.
The patch is to request only SELECT_ACL privilege for INFORMATION_SCHEMA tables.
------------------------------------------------------------
Before the patch, slaves only appear in the output of SHOW SLAVE HOSTS
when report-host option is set. If an expected slave does not appear in
the list, nobody knows whether the slave does not connect or has started
without the "report-host" option. The output also contains a strange
field "Rpl_recovery_rank" which has never been implemented and the manual
of MySQL5.4 declares that the field has been removed from MySQL5.4.
This patch is done with these,
According to the manual of MySQL5.4, "Rpl_recovery_rank" is removed.
Slaves will register themselves to master no matter if report_host option is set
or not. When slaves are registering themselves, their Server_ids, report_host
and other information are together sent to master. Sever_ids are never null
and is unique in one replication group. Slaves always can be identified with
different Server_ids no matter if report_host exists.

message:
Cover four special cases of WL#4166 with tests:
- when the query cache is disabled at the time of prepared statement
reprepare
- when long data parameters are used
- when character_set_connection != character_set_client, and a parameter
conversion takes place
- when parameter data is out of acceptable range, e.g. year 10000 is
supplied as part of MYSQL_TYPE_DATETIME value. The server is supposed
to warn in such case.
mysql-test/include/query_cache_sql_prepare.inc:
Addditional test for Bug#27430
mysql-test/r/query_cache_ps_no_prot.result:
Update result file.
mysql-test/r/query_cache_ps_ps_prot.result:
Update result file.
tests/mysql_client_test.c:
Add more tests (Bug#27430 and WL#4166).
Fix test_datetime_range() test to correctly assert for the number
of warnings. Additionally, print these warnings out.
"have_profiling"
1) Renamed have_community_features server system variable to
have_profiling.
2) Removed eable-community-features configure option and
ENABLE_COMMUNITY_FEATURES macro.
3) Removed COMMUNITY_SERVER macro and replaced its usage by
ENABLED_PROFILING.
Only --enable-profiling is now needed to enable profiling.
It was the only existing "community feature", so there was
no need for both configure options.
Using --enable-community-features will give a warning message
since it no longer exists.
- Remove the "hack" from mtr.pl that skipped searching for the .dll files
when embedded and windows. Now the variables will be preoperly initialized.
- Make the tests detect that they can't run on windows+embedded
