routine does not exist
There is an inconsistency with DROP DATABASE IF EXISTS, DROP TABLE IF
EXISTS and DROP VIEW IF EXISTS: those are binlogged even if the DB or
TABLE does not exist, whereas DROP PROCEDURE IF EXISTS does not. It
would be nice or at least consistent if DROP PROCEDURE/STATEMENT
worked the same too.
Fixed DROP PROCEDURE|FUNCTION IF EXISTS by adding a call to
mysql_bin_log.write in mysql_execute_command. Checked also if all
documented "DROP (...) IF EXISTS" get binlogged.
NOTE: This is a 5.0 backport patch as requested by support.
mysql-test/r/rpl_drop_if_exists.result:
Result file for test case added.
mysql-test/r/rpl_sp.result:
Updated result file for existing test case that has now extra events in
binary log (the ones from drop if exists procedure/function).
mysql-test/t/rpl_drop_if_exists.test:
Added test case for asserting validity of proposed patch.
sql/sql_parse.cc:
Added call mysql_bin_log.write when lex has drop_if_exists enabled for
stored procedures.
The problem is that a SELECT .. FOR UPDATE statement might open
a table and later wait for a impeding global read lock without
noticing whether it is holding a table that is being waited upon
the the flush phase of the process that took the global read
lock.
The same problem also affected the following statements:
LOCK TABLES .. WRITE
UPDATE .. SET (update and multi-table update)
TRUNCATE TABLE ..
LOAD DATA ..
The solution is to make the above statements wait for a impending
global read lock before opening the tables. If there is no
impending global read lock, the statement raises a temporary
protection against global read locks and progresses smoothly
towards completion.
Important notice: the patch does not try to address all possible
cases, only those which are common and can be fixed unintrusively
enough for 5.0.

When the thread executing a DDL was killed after finished its
execution but before writing the binlog event, the error code in
the binlog event could be set wrongly to ER_SERVER_SHUTDOWN or
ER_QUERY_INTERRUPTED.
This patch fixed the problem by ignoring the kill status when
constructing the event for DDL statements.
This patch also included the following changes in order to
provide the test case.
1) modified mysqltest to support variable for connection command
2) modified mysql-test-run.pl, add new variable MYSQL_SLAVE to
run mysql client against the slave mysqld.
due to name_const substitution
Problem:
"In general, statements executed within a stored procedure
are written to the binary log using the same rules that
would apply were the statements to be executed in standalone
fashion. Some special care is taken when logging procedure
statements because statement execution within procedures
is not quite the same as in non-procedure context".
For example, each reference to a local variable in SP's
statements is replaced by NAME_CONST(var_name, var_value).
Queries like
"CREATE TABLE ... SELECT FUNC(local_var ..."
are logged as
"CREATE TABLE ... SELECT FUNC(NAME_CONST("local_var", var_value) ..."
that leads to differrent field names and
might result in "Incorrect column name" if var_value is long enough.
Fix: in 5.x we'll issue a warning in such a case.
In 6.0 we should get rid of NAME_CONST().
Note: this issue and change should be described in the documentation
("Binary Logging of Stored Programs").

(Pushing for Azundris)
We allow security-contexts with NULL users (for
system-threads and for unauthenticated users).
If a non-SUPER-user tried to KILL such a thread,
we tried to compare the user-fields to see whether
they owned that thread. Comparing against NULL was
not a good idea.
If KILLer does not have SUPER-privilege, we
specifically check whether both KILLer and KILLee
have a non-NULL user before testing for string-
equality. If either is NULL, we reject the KILL.

- Strings are guaranteed to be max uint in length
If the system time is adjusted back during a query execution
(resulting in the end time being earlier than the start time)
the code that prints to the slow query log gets confused and
prints unsigned negative numbers.
Fixed by not logging the statements that would have negative
execution time due to time shifts.
No test case since this would involve changing the system time.
sql/sql_parse.cc:
Bug #35396: don't log queries with negative execution times
(due to shifts in system time).
The problem was that the server did not robustly handle a
unilateral roll back issued by the Resource Manager (RM)
due to a resource deadlock within the transaction branch.
By not acknowledging the roll back, the server (TM) would
eventually corrupt the XA transaction state and crash.
The solution is to mark the transaction as rollback-only
if the RM indicates that it rolled back its branch of the
transaction.

When running Stored Routines the Status Variable "Questions" was wrongly
incremented. According to the manual it should contain the "number of
statements that clients have sent to the server"
Introduced a new status variable 'questions' to replace the query_id
variable which currently corresponds badly with the number of statements
sent by the client.
The new behavior is ment to be backward compatible with 4.0 and at the
same time work with new features in a similar way.

The crash was caused by freeing the internal parser stack during the parser
execution.
This occured only for complex stored procedures, after reallocating the parser
stack using my_yyoverflow(), with the following C call stack:
- MYSQLparse()
- any rule calling sp_head::restore_lex()
- lex_end()
- x_free(lex->yacc_yyss), xfree(lex->yacc_yyvs)
The root cause is the implementation of stored procedures, which breaks the
assumption from 4.1 that there is only one LEX structure per parser call.
The solution is to separate the LEX structure into:
- attributes that represent a statement (the current LEX structure),
- attributes that relate to the syntax parser itself (Yacc_state),
so that parsing multiple statements in stored programs can create multiple
LEX structures while not changing the unique Yacc_state.
Now, Yacc_state and the existing Lex_input_stream are aggregated into
Parser_state, a structure that represent the complete state of the (Lexical +
Syntax) parser.

Before this fix, the lexer and parser would treat the ';' character as a
different token (either ';' or END_OF_INPUT), based on convoluted logic,
which failed in simple cases where a stored procedure is implemented as a
single statement, and used in a multi query.
With this fix:
- the character ';' is always parsed as a ';' token in the lexer,
- parsing multi queries is implemented in the parser, in the 'query:' rules,
- the value of thd->client_capabilities, which is the capabilities
negotiated between the client and the server during bootstrap,
is immutable and not arbitrarily modified during parsing (which was the
root cause of the bug)
If during a FLUSH PRIVILEGES the server fails to load the new privilege
tables, the error message is lost. This patch is a back port from 5.1 which
adresses this issue by setting the server in an error state if a failure
occurrs.
This patch also corrects an incorrect variable assignment which might
cause an error state to be reverted by coincidence.
sql/sql_parse.cc:
* Set error state if acl_reload or grant_reload fails.
* Fix bad variable assignment which cancels previous error status.
The bool data type was redefined to BOOL (4 bytes on windows).
Removed the #define and fixed some of the warnings that were uncovered
by this.
Note that the fix also disables 2 warnings :
4800 : 'type' : forcing value to bool 'true' or 'false' (performance warning)
4805: 'operation' : unsafe mix of type 'type' and type 'type' in operation
These warnings will be handled in a separate bug, as they are performance related or bogus.

2 distinct values.

Here is the scenario that causes the failure.(by Mats)
1. The to-be corrupt log event (let's call it X), is split into two
packets B and C on the network level (net_write_buff()). The parts
are X = (x',x''). The part x' ends up in packet B and part x''
ends up in packet C. Prior to the corrupt event X, the event Y has
been written successfully, but has been split into two packets as
well, which we call (y',y'').
2. The master sends packet A = (y'',x') to the slave, increases the
packet sequence number, the slave receives the packet, but fails
to reply before the master gets a timeout.
3. Since the master got a timeout, it reports failure, and aborts
sending the binary log by exiting mysql_binlog_send(). However, it
leaves the buffer intact, still holding y'' (but not x', since the
write_pos is not increased).
4. After exiting mysql_binlog_send(), the master does a
disconnection of the client thread, which involves sending an
error message e to the client (i.e., the slave).
5. In this case, net_write_buff() is used again, but this time the
old contents of the packet is used so that the new packet is
D = (y'',e). Note that this will use a new packet sequence number,
since the packet number was increased in step 2.
6. The slave receives the tail y'' of the Y log event, concatenates
this with x' (which it already received), and writes the event
(x',y'') it to the relay log since it hasn't noticed anything is
amiss.
7. It then tries to read more bytes, which is either e (if the length
given for X just happened to match the length given for Y, or just
plain garbage because the slave is out of sync with what is
actually sent.
8. After a while, the SQL thread tries to execute the event (x',y''),
which is very likely to be just nonsense.
The problem can be fixed by not resetting net->error after the call of
mysql_binlog_send, so the error message will not be sent and the connection
will be closed.
sql/sql_parse.cc:
Do not reset net->error, if net->error == 2, we should not try to use the connection again
When read_only option was enabled, a user without SUPER privilege could

FLUSH TABLES WITH READ LOCK fails to properly detect write locked
tables when running under low priority updates.
The problem is that when trying to aspire a global read lock, the
reload_acl_and_cache() function fails to properly check if the thread
has a low priority write lock, which later my cause a server crash or
deadlock.
The solution is to simple check if the thread has any type of the
possible exclusive write locks.

The root cause of the issue was that the CREATE FUNCTION grammar,
for User Defined Functions, was using the sp_name rule.
The sp_name rule is intended for fully qualified stored procedure names,
like either ident.ident, or just ident but with a default database
implicitly selected.
A UDF does not have a fully qualified name, only a name (ident), and should
not use the sp_name grammar fragment during parsing.
The fix is to re-organize the CREATE FUNCTION grammar, to better separate:
- creating UDF (no definer, can have AGGREGATE, simple ident)
- creating Stored Functions (definer, no AGGREGATE, fully qualified name)
With the test case provided, another issue was exposed which is also fixed:
the DROP FUNCTION statement was using sp_name and also failing when no database
is implicitly selected, when droping UDF functions.
The fix is also to change the grammar so that DROP FUNCTION works with
both the ident.ident syntax (to drop a stored function), or just the ident
syntax (to drop either a UDF or a Stored Function, in the current database)

mysql-test/t/innodb.test:
trans table specific test added
mysql-test/t/mix_innodb_myisam_binlog.test:
multi-update and multi-delete of mixure of ta and not-ta tables tests added (relates to bug_23333).
mysql-test/t/multi_update.test:
testing another branch of mult-delete: send_eof() (binloggin there), send_error (early return)
sql/sql_class.h:
a new flag to designate the fact the statement's error has been handled.
The flag is checked by ::send_error() methods (multi_update and _delete classes)
sql/sql_delete.cc:
expanding multi_delete::send_error to
1. early return if error_handled == t
2. binlogging locally if there was a non-trans table modified side effect
sql/sql_parse.cc:
adding multi_update::send_error which can perform binlogging and rollback job in needed
sql/sql_update.cc:
issues relating to
1. bug_27716 with zeroing of `updated' to serve as the flag of early return from send_error().
The flag is changed to be a new member error_handled; also moved outside binlogging branch.
The reason for this change is that bug_23333 fixes were pushed after the bug_27716's and they
left this flaw (also no test coverage).
2. bug_30763 with assertion on trans_safe. I decide to make 2 liner fix for that bug here instead of to remove
those two assertions. This new bug test case is the same as for multi-update on the mixure of tables.
The rational for this fix:
presumption for mutli_update::trans_safe to be set to zero at
multi_update::multi_update or multi_update::initialize_tables() is incorrect.
trans_safe := false should happen only when a non-transactional table gets modified.
Therefore, at initialization the member must be be set to true.

active_mi has been reset (shutdown) at the time of quering with
SHOW SLAVE STATUS so that
at handling of SHOW an attempt to read its members segfaults.
Fixed with checking the value of active_mi before to call show_master_info()
Merely send_ok() is invoked when active_mi does not exist.
A test can not be easiely written.
Notice, there are more analogical cases in the code which require a similar
treatment (to be reported as a bug separately).
sql/sql_parse.cc:
Ignore reporting and send only OK if master info struct has been destoyed.
As this must be at shutdown merely a warning is sent to the client.
The problem was that aborted_threads variable was updated
twice when a client connection had been aborted.
The fix is to refactor a code to have aborted_threads updated
only in one place.
sql/mysql_priv.h:
Make do_command() a private function.
sql/sql_parse.cc:
1. Make do_command() a private function;
2. Update aborted_threads in the only one place.
Use view db name as thread default database, in order to ensure
that the view is parsed and prepared correctly.

When dumping database from a 4.x server, the mysqldump client
inserted a delimiter sign inside special commentaries of the form:
/*!... CREATE DATABASE IF NOT EXISTS ... ;*/
During restoration that dump file was splitten by delimiter signs on
the client side, and the rest of some commentary strings was prepended
to following statements.
The 4x_server_emul test case option has been added for use with the
DBUG_EXECUTE_IF debugging macro. This option affects debug server
builds only to emulate particular behavior of a 4.x server for
the mysqldump client testing. Non-debugging builds are not affected.
mysql-test/r/mysqldump-compat.result:
Added test case for bug #30126.
mysql-test/t/mysqldump-compat.opt:
Added test case for bug #30126.
mysql-test/t/mysqldump-compat.test:
Added test case for bug #30126.
sql/sql_parse.cc:
Fixed bug #30126.
The mysqldump client uses the "SHOW CREATE DATABASE" query to
obtain the "CREATE DATABASE" statement from that database.
The 4.x server doesn't recognise that query, and mysqldump
forms the "CREATE DATABASE" statement from scratch.
That statement was formed incorrectly.
To enforce the mysqldump client to create that statement from
scratch, debugging code has been added to the mysql_execute_command
function: in tcase of the --loose-debug=d,4x_server_emul option,
the server returns parse error to client to emulate old behaviour.
The 4x_server_emul test case option has been added for use with the
DBUG_EXECUTE_IF debugging macro. This option affects debug server
builds only to emulate particular behavior of a 4.x server for
the mysqldump client testing. Non-debugging builds are not affected.
client/mysqldump.c:
Fixed bug #30126.
The init_dumping_tables function has been modified to output semicolon
outside of commentaries.
