will create multiple running events.
A CREATE IF NOT EXIST on an event that existed and was enabled caused
multiple instances of the event to run. Disabling the event didn't help.
If the event was dropped, the event stopped running, but when created
again, multiple instances of the event were still running. The only way
to get out of this situation was to restart the server.
The problem was that Event_db_repository::create_event() didn't return
enough information to discriminate between situation when event didn't
exist and was created and when event did exist and was not created
(but a warning was emitted). As result in the latter case event
was added to in-memory queue of events second time. And this led to
unwarranted multiple executions of the same event.
The solution is to add out-parameter to Event_db_repository::create_event()
method which will signal that event was not created because it already
exists and so it should not be added to the in-memory queue.
mysql-test/r/events_bugs.result:
Added results for test for Bug#12546938.
mysql-test/t/events_bugs.test:
Added test for Bug#12546938.
sql/event_db_repository.cc:
Event_db_repository::create_event was modified: set newly added out-parameter
event_already_exists to true value if event wasn't created because event
already existed and IF NOT EXIST clause was present.
sql/event_db_repository.h:
Added out-parameter 'event_already_exists' to create_event() method.
sql/events.cc:
Events::create_event was modified: insert new element into
event queue only if event was actually created.

NOTE
====
mysql-5.1-rpl-merge has been made a mirror of mysql-next-mr:
- "mysql-5.1-rpl-merge$ bzr pull ../mysql-next-mr"
This is the first cset (merge/...) committed after pulling
from mysql-next-mr.
The problem is that creating a event could fail if the value of
the variable server_id didn't fit in the originator column of
the event system table. The cause is two-fold: it was possible
to set server_id to a value outside the documented range (from
0 to 2^32-1) and the originator column of the event table didn't
have enough room for values in this range.
The log tables (general_log and slow_log) also don't have a proper
column type to store the server_id and having a large server_id
value could prevent queries from being logged.
The solution is to ensure that all system tables that store the
server_id value have a proper column type (int unsigned) and that
the variable can't be set to a value that is not within the range.

3. Add poll routines which ensure that subtests meet stable scenarios.
This does not change the sense of the subtests.
Bug#39848 events_bugs fails sporadically on pushbuild
(missing rows in table event_log)
Details: Reimplement the subtest for BUG 28924
- check if the number of rows within the table
event_log changes but don't print rows
because the number varies depending on
load on testing box
- shift DROP USER befor DROP EVENT
= Subtest fits again to old bug
- remove no more needed comments + variables
Bug#39863 events_bugs fails sporadically on pushbuild
(extra processes in I_S.PROCESSLIST)
Details: Abort with appropriate message to the protocol if
release_lock() does not has the intended effect.
This cannot prevent problems caused by the probably
buggy release_lock() but it reveals if we had a
problem in this area.
Bug#39978 main.events_bugs does not clean up
Detail: Restore global.event_scheduler = ON at end of test
Bug#39569 events_bugs fails sporadically on pushbuild
(should have failed with errno 1539)
Detail: Set $wait_timeout to 4 instead of 2
- Fix two instabilities (result sets pulled from processlist in
subtest for bug 16407) which were found during tests with high
parallel I/O load
- Minor improvements of formatting
Details:
- Add comments
- Remove tabs and trailing blanks
- Add line breaks for better readability
The problem is that one can not create a stored routine if sql_mode
contains NO_ENGINE_SUBSTITUTION or PAD_CHAR_TO_FULL_LENGTH. Also when
a event is created, the mode is silently lost if sql_mode contains one
of the aforementioned. This was happening because the table definitions
which stored sql_mode values weren't being updated to accept new values
of sql_mode.
The solution is to update, in a backwards compatible manner, the various
table definitions (columns) that store the sql_mode value to take into
account the new possible values. One incompatible change is that if a event
that is being created can't be stored to the mysql.event table, an error
will be raised.
The tests case also ensure that new SQL modes will be added to the mysql.proc
and mysql.event tables, otherwise the tests will fail.

There actually were several problems here:
- WRITE-lock is required to load events from the mysql.event table,
but in the read-only mode an ordinary user can not acquire it;
- Security_context::master_access attribute was not properly
initialized in Security_context::init(), which led to differences
in behavior with and without debug configure options.
- if the server failed to load events from mysql.event, it forgot to
close the mysql.event table, that led to the coredump, described
in the bug report.
The patch is to fix all these problems:
- Use the super-user to acquire WRITE-lock on the mysql.even table;
- The WRITE-lock is acquired by the event scheduler in two cases:
- on initial loading of events from the database;
- when an event has been executed, so its attributes should
be updated.
Other cases when WRITE-lock is needed for the mysql.event table
happen under the user account. So, nothing should be changed there
for the read-only mode. The user is able to create/update/drop
an event only if he is a super-user.
- Initialize Security_context::master_access;
- Close the mysql.event table in case something went wrong.
mysql-test/r/events_bugs.result:
Update result file.
mysql-test/t/events_bugs.test:
A test case for BUG#31111: --read-only crashes MySQL (events fail

sql/event_data_objects.cc:
When the worker thread is going to drop event after the execution
we should do it under the super-user privileges in order to be able
to lock the mysql.event table for writing in the read-only mode.
This is a system operation, where user SQL can not be executed.
So, there is no risk in compromising security by dropping an event
under the super-user privileges.
sql/event_db_repository.cc:
1. Close tables if something went wrong in simple_open_n_lock_tables();
2. As soon as the system event scheduler thread is running under
the super-user privileges, we should always be able to acquire
WRITE-lock on the mysql.event table. However, let's have an assert
to check this.
sql/event_scheduler.cc:
Run the system event scheduler thread under the super-user privileges.
In particular, this is needed to be able to lock the mysql.event table
for writing when the server is running in the read-only mode.
The event scheduler executes only system operations and does not
execute user SQL (this is what the worker threads for). So, there
is no risk in compromising security by running the event scheduler
under the super-user privileges.
sql/events.cc:
Open the mysql.event table as the super user to be able to acquire
WRITE-lock in the read-only mode.
sql/sql_class.cc:

Creating an EVENT to be executed at a time close to the end of the allowed
range (2038.01.19 03:14:07 UTC) would cause the server to crash. The
expected behavior is to accept all calendar times within the interval and
reject all other values without crashing.
This patch replaces the function 'sec_to_epoch_TIME' with a Time_zone API call.
This function was broken because it invoked the internal function 'sec_to_epoch'
without respecting the restrictions on the function parameters (and this caused
assertion failure). It also was used as a reverse function to
Time_zone_utc::gmt_sec_to_TIME which it isn't.

sql/event_data_objects.cc:
Replaced function 'sec_since_epoch_TIME' since it was implemented as

into account. The function was used to load information about event
execution time from mysql.events table. Further more, the function wasn't
the inverse function of Time_zone_utc::gmt_sec_to_TIME() which was used
by events code to store information about event execution time.
sql/event_db_repository.cc:
Replaced my_tz_UTC object with my_tz_OFFSET0 object because the first one
doesn't supply us with a bijective MYSQL_TIME<->my_time_t translation. Instead
the function sec_since_epoch_TIME was used as a reverse function to the method
my_tz_UTC::gmt_sec_to_TIME.
sql/event_queue.cc:
Replaced my_tz_UTC object with my_tz_OFFSET0 object because the first one

my_tz_UTC::gmt_sec_to_TIME.

- BUG#21249: Character set of SP-var can be ignored
- BUG#25212: Character set of string constant is ignored (stored routines)
- BUG#25221: Character set of string constant is ignored (triggers)
There were a few general problems that caused these bugs:
1. Character set information of the original (definition) query for views,
triggers, stored routines and events was lost.
2. mysqldump output query in client character set, which can be
inappropriate to encode definition-query.
3. INFORMATION_SCHEMA used strings with mixed encodings to display object
definition;
1. No query-definition-character set.
In order to compile query into execution code, some extra data (such as
environment variables or the database character set) is used. The problem
here was that this context was not preserved. So, on the next load it can
differ from the original one, thus the result will be different.
The context contains the following data:
- client character set;
- connection collation (character set and collation);
- collation of the owner database;
The fix is to store this context and use it each time we parse (compile)
and execute the object (stored routine, trigger, ...).
2. Wrong mysqldump-output.
The original query can contain several encodings (by means of character set
introducers). The problem here was that we tried to convert original query
to the mysqldump-client character set.
Moreover, we stored queries in different character sets for different
objects (views, for one, used UTF8, triggers used original character set).
The solution is
- to store definition queries in the original character set;
- to change SHOW CREATE statement to output definition query in the
binary character set (i.e. without any conversion);
- introduce SHOW CREATE TRIGGER statement;
- to dump special statements to switch the context to the original one
before dumping and restore it afterwards.
Note, in order to preserve the database collation at the creation time,
additional ALTER DATABASE might be used (to temporary switch the database
collation back to the original value). In this case, ALTER DATABASE
privilege will be required. This is a backward-incompatible change.
3. INFORMATION_SCHEMA showed non-UTF8 strings
The fix is to generate UTF8-query during the parsing, store it in the object
and show it in the INFORMATION_SCHEMA.
Basically, the idea is to create a copy of the original query convert it to
UTF8. Character set introducers are removed and all text literals are
converted to UTF8.
This UTF8 query is intended to provide user-readable output. It must not be
used to recreate the object. Specialized SHOW CREATE statements should be
used for this.
The reason for this limitation is the following: the original query can
contain symbols from several character sets (by means of character set
introducers).
Example:
- original query:
CREATE VIEW v1 AS SELECT _cp1251 'Hello' AS c1;
- UTF8 query (for INFORMATION_SCHEMA):
CREATE VIEW v1 AS SELECT 'Hello' AS c1;
