013136364c Bug#54416 MAX from JOIN with HAVING returning NULL with 5.1 and Empty set
The problem there is that HAVING condition evaluates const
parts of condition despite the condition has references
on aggregate functions. Table t1 became const tables
after make_join_statistics and table1.pk = 1, HAVING is
transformed into MAX(1) < 7 and taken away from HAVING.
The fix is to skip evaluation of HAVING conts parts if
HAVING condition has references on aggregate functions.

0e6560398c Bug#54477: Crash on IN / CASE with NULL arguments
Incorrect handling of NULL arguments could lead to a crash on
the IN or CASE operations when either NULL arguments were
passed explicitly as arguments (IN) or implicitly generated by
the WITH ROLLUP modifier (both IN and CASE).

Item_func_case::find_item() assumed all necessary comparators
to be instantiated in fix_length_and_dec(). However, in the
presence of WITH ROLLUP modifier, arguments could be
substituted with an Item_null leading to an "unexpected"
STRING_RESULT comparator being invoked.

In addition to the problem identical to the above,
Item_func_in::val_int() could crash even with explicitly passed
NULL arguments due to an optimization in fix_length_and_dec()
leading to NULL arguments being ignored during comparators
creation.

b36a028224 Bug#50389 Using intersect does not return all rows
In process of record search it is not taken into account
that inital quick->file->ref value could be inapplicable
to range interval. After proper row is found this value is
stored into the record buffer and later the record is
filtered out at condition evaluation stage.
The fix is store a refernce of found row to the handler ref field.

ec281a3c34 Fixed some bugs in the Maria storage engine
- Changed default recovery mode from OFF to NORMAL to get automatic repair of not properly closed tables.
- Fixed a rase condition when two threads calls external_lock and thr_lock() in different order. When this happend the transaction that called external lock first
  and thr_lock() last did not see see the rows from the other transaction, even if if it had to wait in thr_lock() for other to complete.
- Fixed that one can run maria_chk on an automatcally recovered tables without warnings about too small transaction id
- Don't give warning that crashed table could not be repaired if repair was disabled (and thus not run)
- Fixed a error result from flush_key_cache() which caused a DBUG_ASSERT() when one was using concurrent reads on non transactional tables that was updated.

storage/maria/ha_maria.cc:
  Changed default recovery mode from OFF to NORMAL to get automatic repair of not properly closed tables.
  Start transaction in ma_block_get_status() instead of in ha_maria::external_lock().
  - This fixes a rase condition when two threads calls external lock and thr_lock() in different order. When this happend the transaction that called external lock first and thr_lock() last did not see see the rows from the other transaction, even if if it had to wait in thr_lock() for other to complete.
  Store latest transaction id in controll file if recovery was done.
  - This allows one to run maria_chk on an automatcally recovered tables without warnings about too small transaction id
storage/maria/ha_maria.h:
  Don't give warning that crashed table could not be repaired if repair was disabled (and thus not run)
storage/maria/ma_blockrec.h:
  Added new function "_ma_block_get_status_no_versioning()"
storage/maria/ma_init.c:
  Added hook to create trn in ma_block_get_status() if we are using MariaDB
storage/maria/ma_open.c:
  Ensure we call _ma_block_get_status_no_versioning() for transactional tables without versioning (like tables with fulltext)
storage/maria/ma_pagecache.c:
  Allow one to flush blocks that are pinned for read.
  This fixed a error result from flush_key_cache() which caused a DBUG_ASSERT() when one was using concurrent reads on non transactional tables that was updated.
storage/maria/ma_recovery.c:
  Set maria_recovery_changed_data to 1 if recover changed something.
  Set max_trid_in_control_file to max found trn if we found a bigger trn.
  The allows will ensure that the control file is up to date after recovery which allows one to run maria_chk on the tables without warnings about too big trn
storage/maria/ma_state.c:
  Call maria_create_trn_hook() in _ma_setup_live_state() instead of ha_maria::external_lock()
  This ensures that 'state' and trn are in sync and thus fixes the race condition mentioned for ha_maria.cc
storage/maria/ma_static.c:
  Added maria_create_trn_hook() and maria_recovery_changed_data
storage/maria/maria_def.h:
  Added MARIA_HANDLER->external_ptr, which is used to hold MariaDB thd.
  Added some new external variables
  Removed reference to non existing function: maria_concurrent_inserts()

0823afc8bf Bug#53859: Valgrind: opt_sum_query(TABLE_LIST*, List<Item>&,
Item*) at opt_sum.cc:305
      
Queries applying MIN/MAX functions to indexed columns are
optimized to read directly from the index if all key parts
of the index preceding the aggregated key part are bound to
constants by the WHERE clause. A prefix length is also
produced, equal to the total length of the bound key
parts. If the aggregated column itself is bound to a
constant, however, it is also included in the prefix.

Such full search keys are read as closed intervals for
reasons beyond the scope of this bug. However, the procedure
missed one case where a key part meant for use as range
endpoint was being overwritten with a NULL value destined
for equality checking. In this case the key part was
overwritten but the range flag remained, causing open
interval reading to be performed.

Bug was fixed by adding more stringent checking to the
search key building procedure (matching_cond) and never
allow overwrites of range predicates with non-range
predicates.

An assertion was added to make sure open intervals are never
used with full search keys.

Some of the server implementations don't support dates later
than 2038 due to the internal time type being 32 bit.
Added checks so that the server will refuse dates that cannot
be handled by either throwing an error when setting date at 
runtime or by refusing to start or shutting down the server if 
the system date cannot be stored in my_time_t.

f3a8307397 Bug #48537: difference of index selection between rpm binary
and .tar.gz, windows vs linux..

On Intel x86 machines index selection by the MySQL query
optimizer could sometimes depend on the compiler version and
optimization flags used to build the server binary.

The problem was a result of a known issue with floating point
calculations on x86: since internal FPU precision (80 bit)
differs from precision used by programs (32-bit float or 64-bit
double), the result of calculating a complex expression may
depend on how FPU registers are allocated by the compiler and
whether intermediate values are spilled from FPU to memory. In
this particular case compiler versions and optimization flags
had an effect on cost calculation when choosing the best index
in best_access_path().

A possible solution to this problem which has already been
implemented in mysql-trunk is to limit FPU internal precision
to 64 bits. So the fix is a backport of the relevant code to
5.1 from mysql-trunk.

  Configure check for fpu_control.h

0a35e5bd18 A 5.1-only version of fix for bug #46947 "Embedded SELECT
without FOR UPDATE is causing a lock".

SELECT statements with subqueries referencing InnoDB tables
were acquiring shared locks on rows in these tables when they
were executed in REPEATABLE-READ mode and with statement or
mixed mode binary logging turned on.

This was a regression which were introduced when fixing
bug 39843.

The problem was that for tables belonging to subqueries
parser set TL_READ_DEFAULT as a lock type. In cases when
statement/mixed binary logging at open_tables() time this
type of lock was converted to TL_READ_NO_INSERT lock at
open_tables() time and caused InnoDB engine to acquire
shared locks on reads from these tables. Although in some
cases such behavior was correct (e.g. for subqueries in
DELETE) in case of SELECT it has caused unnecessary locking.

This patch implements minimal version of the fix for the
specific problem described in the bug-report which supposed
to be not too risky for pushing into 5.1 tree.
The 5.5 tree already contains a more appropriate solution
which also addresses other related issues like bug 53921
"Wrong locks for SELECTs used stored functions may lead
to broken SBR".

This patch tries to solve the problem by ensuring that
TL_READ_DEFAULT lock which is set in the parser for
tables participating in subqueries at open_tables()
time is interpreted as TL_READ_NO_INSERT or TL_READ.
TL_READ is used only if we know that this is a SELECT
and that this particular table is not used by a stored
function.

Test coverage is added for both InnoDB and MyISAM.

This patch introduces an "incompatible" change in locking
scheme for subqueries used in SELECT ... FOR UPDATE and
SELECT .. IN SHARE MODE.

In 4.1 (as well as in 5.0 and 5.1 before fix for bug 39843)
the server would use a snapshot InnoDB read for subqueries
in SELECT FOR UPDATE and SELECT .. IN SHARE MODE statements,
regardless of whether the binary log is on or off.

If the user required a different type of read (i.e. locking
read), he/she could request so explicitly by providing FOR
UPDATE/IN SHARE MODE clause for each individual subquery.

The patch for bug 39843 broke this behaviour (which was not
documented or tested), and started to use locking reads for
all subqueries in SELECT ... FOR UPDATE/IN SHARE MODE.
This patch restores 4.1 behaviour.

This patch should be mostly null-merged into 5.5 tree.

  which lock type to be determined belongs to prelocking list.
sql/sql_base.cc:
  Changed read_lock_type_for_table() to return a weak TL_READ
  type of lock in cases when we are executing SELECT (and so
  won't update tables directly) and table doesn't belong to
  statement's prelocking list and thus can't be used by a
  stored function. It is OK to do so since in this case table
  won't be used by statement or function call which will be
  written to the binary log, so serializability requirements
  for it can be relaxed.
  One of results from this change is that SELECTs on InnoDB
  tables no longer takes shared row locks for tables which
  are used in subqueries (i.e. bug #46947 is fixed).
  Another result is that for similar SELECTs on MyISAM tables
  concurrent inserts are allowed.
  In order to implement this change signature of
  read_lock_type_for_table() function was changed to
  take pointers to LEX and TABLE_LIST objects.

8ede529b36 Bug#52005 'JOIN_TAB->dependent' may be incorrectly propageted for multilevel outer joins
There are two problems:
1. In simplify_joins function we calculate table dependencies. If STRAIGHT_JOIN hint
is used for whole SELECT we do not count it and as result some dependendecies
might be lost. It leads to incorrect table order which is returned by
join_tab_cmp_straight() function.
2. make_join_statistics() calculate the transitive closure for relations a particular
JOIN_TAB is 'dependent on'.
We aggregate the dependent table_map of a JOIN_TAB by adding dependencies from other
tables which we depend on. However, this may also cause new dependencies to be
available after we have completed processing a certain JOIN_TAB.
Both these problems affect condition pushdown and as result condition might be pushed
into wrong table which leads to crash or even omitted which leads to wrong result.
The fix:
1. Use modified 'transitive closure' algorithm provided by Ole John Aske
2. Update table dependences in simplify_joins according to 
   global STRAIGHT_JOIN hint.
Note: the patch also fixes bugs 46091 & 51492

1d0acc7754 Bug #53830: !table || (!table->read_set ||
bitmap_is_set(table->read_set, field_index))

UPDATE on an InnoDB table modifying the same index that is used
to satisfy the WHERE condition could trigger a debug assertion
under some circumstances.

Since for engines with the HA_PRIMARY_KEY_IN_READ_INDEX flag
set results of an index scan on a secondary index are appended
by the primary key value, if a query involves only columns from
the primary key and a secondary index, the latter is considered
to be covering.

That tricks mysql_update() to mark for reading only columns
from the secondary index when it does an index scan to retrieve
rows to update in case a part of that key is also being
updated. However, there may be other columns in WHERE that are
part of the primary key, but not the secondary one.

What we actually want to do in this case is to add index
columns to the existing WHERE columns bitmap rather than
replace it.

c2ebb0ac88 Bug #42064: low memory crash when importing hex strings, in
Item_hex_string::Item_hex_string

The status of memory allocation in the Lex_input_stream (called
from the Parser_state constructor) was not checked which led to
a parser crash in case of the out-of-memory error.

The solution is to introduce new init() member function in
Parser_state and Lex_input_stream so that status of memory
allocation can be returned to the caller.

Server crashes on 64bit linux with 'double free or corruption'
message, on 32bit mysql-test-run silently fails on bootstrap

for init_settings struct in _db_end_ function.
The fix is to remove superfluous FreeState() call.
Additional fix:
fixed discrepancy of result file when

Single-table DELETE crash/assertion similar to single-table
UPDATE bug 14272.

Same resolution as for the bug 14272:
Don't run index scan when we should use quick select.
This could cause failures because there are table handlers (like federated)
that support quick select scanning but do not support index scanning.

- Some bugs fixed in opt_range() where we table->key_read was wrongly used



.bzrignore:
  Ignore new xtstat binary
mysql-test/r/index_merge_myisam.result:
  Update results (old result was wrong)
mysql-test/suite/binlog/r/binlog_stm_binlog.result:
  Added drop table first
mysql-test/suite/binlog/r/binlog_stm_unsafe_warning.result:

scripts/make_binary_distribution.sh:
  Removed type from last commit
sql/item_create.cc:
  Don't require row based logging when using RAND() with INSERT
sql/opt_range.cc:
  Revert wrong patch from Oracle:
  - As QUICK_RANGE_SELECT uses it's own 'file' handler to the tables, one can't use 'table->key_read' as a flag to detect if index only read (keyread) is used or not
  - Don't set keyread if keyread is already enabled
  - Don't disable key read, if we didn't enable it ourselves
  - Simplify code (and ensure that we do proper cleanup of index only read)
sql/opt_range.h:
  Added flags to detect if the range optimizer enabled index only read (key read) or not
sql/opt_sum.cc:
  Use our more optimized macros
sql/sql_lex.h:
  Added 'readable' function to check if we are in a sub query function or not (not normal query or sub query in FROM clause)
sql/sql_select.cc:
  Use our more optimized keyread macros
  Added ASSERTS early
  Simplify code on eliminate_item_equal()
  Fixed that substitute_for_best_equal_field() doesn't core dump in case of out of memory conditions.
  Removed not needed test for 'field->maybe_null()'
  Replaced master_unit()->item with is_subquery_function() (More readable)
sql/sql_update.cc:

feb03a82f2 Fix for bug#52051: Aggregate functions incorrectly returns
NULL from outer join query
      
      Problem: optimising MIN/MAX() queries without GROUP BY clause
      by replacing the aggregate expression with a constant, we may set it
      to NULL disregarding the fact that there may be outer joins involved.
      
      Fix: don't replace MIN/MAX() with NULL if there're outer joins.
      
      Note: the fix itself is just
      - if (!count)
      + if (!count && !outer_tables)
          set to NULL
      
      The rest of the patch eliminates repeated code to improve speed
      and for easy maintenance of the code.

sql/opt_sum.cc:
          Fix for bug#52051: Aggregate functions incorrectly returns
          NULL from outer join query
            - optimising MIN/MAX() queries without GROUP BY clause by
          replacing them with a constant, take into account that
          there're may be outer joins involved.
            - repeated code for MIN/MAX optimization in the opt_sum_query()
          eliminated by introducing new functions that read MIN/MAX values
          using index and combining MIN/MAX cases to one.

330864fcda Bug #49756 Rows_examined is always 0 in the slow query log for
update statements
      
Only SELECT statements report any examined rows in the slow
log. Slow UPDATE, DELETE and INSERT statements report 0 rows
examined, unless the statement has a condition including a
SELECT substatement.
      
This patch adds counting of examined rows for the UPDATE and
DELETE statements. An INSERT ... VALUES statement will still 
not report any rows as examined.



sql/sql_class.h:
  Added more docs for THD::examined_row_count.
sql/sql_delete.cc:
  Add incrementing thd->examined_row_count.
sql/sql_update.cc:
  Add incrementing thd->examined_row_count.

6d0425b18d Bug#50939: Loose Index Scan unduly relies on engine to
remember range endpoints

The Loose Index Scan optimization keeps track of a sequence
of intervals. For the current interval it maintains the
current interval's endpoints. But the maximum endpoint was
not stored in the SQL layer; rather, it relied on the
storage engine to retain this value in-between reads. By
coincidence this holds for MyISAM and InnoDB. Not for the
partitioning engine, however.

Fixed by making the key values iterator 
(QUICK_RANGE_SELECT) keep track of the current maximum endpoint.
This is also more efficient as we save a call through the
handler API in case of open-ended intervals.

The code to calculate endpoints was extracted into 
separate methods in QUICK_RANGE_SELECT, and it was possible to
get rid of some code duplication as part of fix.
