warnings after uncompressed_length
UNCOMPRESSED_LENGTH() did not validate its argument. In
particular, if the argument length was less than 4 bytes,
an uninitialized memory value was returned as a result.
Since the result of COMPRESS() is either an empty string or
a 4-byte length prefix followed by compressed data, the bug was
fixed by ensuring that the argument of UNCOMPRESSED_LENGTH() is
either an empty string or contains at least 5 bytes (as done in
UNCOMPRESS()). This is the best we can do to validate input
without decompressing.

It turns out that this test case no longer fails with the discrepancy
in numbers that was the original cause for disabling this test (and showed
potential genuine issues with the query cache). Therefore
this test is being enabled after some minor adjustment of error codes and
messages.
Details:
1. Add missing "disconnect <session>"
2. Take care that the disconnects are finished when the test terminates
3. Replace error names by error numbers
4. Minor beautifying of script code
Field_time::get_time() did not initialize some members of
MYSQL_TIME which led to valgrind warnings when those members
were accessed in Protocol_simple::store_time().
It is unlikely that this bug could result in wrong data
being returned, since Field_time::get_time() initializes the
'day' member of MYSQL_TIME to 0, so the value of 'day'
in Protocol_simple::store_time() would be 0 regardless
of the values for 'year' and 'month'.

In UNION if we use last SELECT without braces and this
SELECT have ORDER BY clause, such clause belongs to
global UNION. It is parsed like last SELECT
part and used further as 'unit->global_parameters->order_list' value.
During DESCRIBE EXTENDED we call select_lex->print_order() for
last SELECT where order fields refer to tmp table
which already freed. It leads to crash.
The fix is clean up global_parameters->order_list
instead of fake_select_lex->order_list.

Problem: using LOAD_FILE() in some cases we pass a file name string

Problem: storing "SELECT ... INTO @var ..." results in variables we used val_xxx()
methods which returned results of the current row.
So, in some cases (e.g. SELECT DISTINCT, GROUP BY or HAVING) we got data

data from the last row of the previous group.
Fix: use val_xxx_result() counterparts to get proper results.

The --hexdump option crashed mysqlbinlog when used together
with the --read-from-remote-server option due to use of
uninitialized memory.
Since Log_event::print_header() relies on temp_buf to be
initialized when the --hexdump option is present,
dump_remote_log_entries() was fixed to setup temp_buf to point
to the start of a binlog event as done in
dump_local_log_entries().
The root cause of this bug is identical to the one for
bug #17654. The latter was fixed in 5.1 and up, so this
patch is backport of the patches for bug #17654 to 5.0.
Only 5.0 needs a changelog entry.
client/mysqlbinlog.cc:
Fixed dump_remote_log_entries() so that temp_buf is initialized
as it may be used later by Log_event::print_header() if the
--hexdump option is present.

Multiple-table DELETE from a table joined to itself may cause
server crash. This was originally discovered with MEMORY engine,

another (delete on the fly optimization).

EXPLAIN EXTENDED of nested query containing a error:
1054 Unknown column '...' in 'field list'
may cause a server crash.
Parse error like described above forces a call to
JOIN::destroy() on malformed subquery.
That JOIN::destroy function closes and frees temporary
tables. However, temporary fields of these tables
may be listed in st_select_lex::group_list of outer
query, and that st_select_lex may not cleanup them
properly. So, after the JOIN::destroy call that
st_select_lex::group_list may have Item_field
objects with dangling pointers to freed temporary
table Field objects. That caused a crash.

The issue of the current bug is unguarded access to mi->slave_running
by the shutdown thread calling end_slave() that is bug#29968
(alas happened not to be cross-linked with the current bug)
Fixed:
with removing the unguarded read of the running status
and perform reading it in terminate_slave_thread()
at time run_lock is taken (mostly bug#29968 backporting, still with some
improvements over that patch - see the error reporting from
terminate_slave_thread()).
Issue of bug#38716 is fixed here for 5.0 branch as well.

Bug #40925: Equality propagation takes non indexed attribute
Query execution plans and execution time of queries like
select a, b, c from t1

"b = a" and "a = b" are not same.

1) BUG#43309 - Test main.innodb can't be run twice
Detailed revision comments:
r4701 | vasil | 2009-04-13 17:03:46 +0300 (Mon, 13 Apr 2009) | 6 lines
branches/5.0:
Fix Bug#43309 Test main.innodb can't be run twice
by making the innodb.test reentrant.
mysqldump.test is designed to run with concurrent inserts
disabled. It is disabling concurrent inserts at the very
beginning of the test case, and re-enables them at the
bottom of the test. But for some reason (likely incorrect
merge) we enable concurrent inserts in the middle of the test.
The problem is fixed by enabling concurrent inserts only
at the bottom of the test case.
to wrong results
3 problems found with DES_ENCRYPT/DES_DECRYPT :
1. The max length was not calculated properly. Fixed in fix_length_and_dec()
2. DES_ENCRYPT had a side effect of sometimes reallocating and changing
the value of its argument. Fixed by explicitly pre-allocating the necessary
space to pad the argument with trailing '*' (stars) when calculating the
DES digest.
3. in DES_ENCRYPT the string buffer for the result value was not
reallocated to the correct size and only string length was assigned to it.
Fixed by making sure there's enough space to hold the result.

This is not a guarantee that we will not see test timeouts (the random failures noted in the bug),
but it should significantly reduce the chances of this occurring.
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.

Testcase for BUG#43973
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.

Original commentary:
Bug #37348: Crash in or immediately after JOIN::make_sum_func_list
The optimizer pulls up aggregate functions which should be aggregated in
an outer select. At some point it may substitute such a function for a field
in the temporary table. The setup_copy_fields function doesn't take this
into account and may overrun the copy_field buffer.
Fixed by filtering out the fields referenced through the specialized
reference for aggregates (Item_aggregate_ref).
Added an assertion to make sure bugs that cause similar discrepancy
don't go undetected.
